Abstract:
The aim of using any in vitro method is to obtain a good description of the nutritional value of forages as they are fed, which in most cases is on a fresh basis. The in vitro gas production technique has the potential to characterise fermentation pattern of the carbohydrate fractions of forages, and has been used extensively with forage material that has been dried and ground through a 1mm screen. The objective of the present study was to compare the fermentation patterns of fresh and dry forage.

Abstract:
Abstract Winter feeds costs for small ruminants exceeds 50% of the total cost of most small ruminant production systems in the Southeastern U.S. Keeping these feed costs low is one of the most effective and time-tested ways to improve farm profitability. While maintaining an appropriate stocking rate will be critical for sustaining long-term farm productivity, a suite of other management practices is available to assist in this objective. Installing appropriate fence and watering system infrastructure for managing grazing will be critical for improving harvest efficiency and stockpiling forages for utilization when forage growth is limited. Filling gaps in forage production may also be achieved through the strategic use of a number of forage species, including warm-season or cool-season forages and annual or perennial forages. Managing stored forages appropriately during storing and feeding will help minimize feed losses, while producing quality hay will reduce the need for supplementary feeds. With the adoption of these proven practices, sheep and goat production may be optimized by allowing them to harvest their own feed almost year-round in the Southeastern U.S.

Abstract:
Brazil is one the largest soybean and cattle producer worldwide and degrade pasture is one of the major problem in the Cerrado region. Integrated crop-livestock system is a key to increase grower income, to reduce crop yield loss by water deficit during growing season and to reclaim degraded pasture. However, forage production and its quality is important to evaluate under integrated crop-livestock system. The objective of this study was to evaluate forage production and the bromatological composition of different forage species in monoculture and in intercropping with soybean in an oversowing system. A completely randomized block design with four replications in a 5 × 2 + 1 factorial scheme, with five forage species (Urochloa brizantha cv. Marandu; U. ruziziensis; P. maximus cv. Mombaça; P. infestans cv. Massai and P. americanum) and two cropping systems (monoculture and a consortium with soybeans) and a standard treatment (P. americanum in succession with soybeans). The forage productivity and the bromatological composition of the forages were evaluated. The species U. ruziziensis, U. brizantha, M. maximum and P. infestans presented higher forage production capacity, when cultivated in consortium with soybeans and in monoculture, in relation to P. americanum. The cultivation of the forages U. ruziziensis, U. brizantha, M. maximum and P. americanum in monoculture produced higher productivity than that in consortium with soybeans. The forages U. ruziziensis and U. brizantha intercropped with soybean presented a better nutritional value over the autumn-winter period.

Abstract:
This experiment aimed to investigate the associative effects among two low-quality forages (crown daisy, milk thistle) and three agro-industrial byproducts (apple pomace, citrus pulp, tomato peel), by means of an automated gas production (GP) system. All feeds were incubated alone or as 50 : 50 mixtures of each forage with each byproduct. Samples (0.500 ± 0.0010 g) of single feeds or mixtures were incubated for 96 h, in three replicates in individual bottles (310 mL), with 75 mL of buffered rumen fluid. Bottles were vented by an open-close valve when the internal pressure reached 3.4 kPa. The metabolisable energy content of single feeds and mixtures was computed from GP at 24 h and feed chemical composition. Feed substrates were ranked for GP in the following way: byproducts, mixtures, and forages. The two forages did not differ for GP and metabolisable energy content, although differences were observed among byproducts and among mixtures. Both forages interacted positively with apple pomace from 6 h (P < 0.001) to 24 h (P = 0.029) of incubation and with citrus pulp at 12 h (P = 0.005) and 24 h (P = 0.012), whereas no associative effects were detected when forages were incubated with tomato peels. Results suggest that in vitro fermentability of low-quality forages could be efficiently improved by combining these two forages with apple pomace or citrus pulp. These findings are relevant, because the use of low-quality forages and byproducts in ruminant feeding is considered important for improving the environmental and economic sustainability of forage systems in arid and semi-arid areas.

A study on the perception and utilization ofimproved forages grown in natural resource conservation areas was conducted in selected districts of northwestern Ethiopia. This studyaims to investigate the perception of improved forage production and utilization system on natural resource conservation areas inselected areas of northwestern Ethiopia. Primary data was collected from selected households by interviewing using semi-structuredquestionnaire. Field observation and focus group discussion were also employed to enhance the survey data. A total of 180 households(90 from each district) were selected and interviewed. The collected data were analyzed with descriptive statistics using SPSS softwareversion 20. The result indicated that the average land and livestock holding of respondents were 2.24 ha and 5.56 TLU per household,respectively. The most common forage production methods used by the smallholder farmers were broadcasting (41%), cutting (28%)and row seedling (18%) for both districts. For the majority of respondents (44%), the purpose of forage production of respondents wasfor animal fodder. Farmers in the study areas had a good perception about improved forage production as forages due havemultifunction to the household in the form of soil conservation, fodder production, and income generation. Though improved forageshave many roles in the livelihood and environmental management of the study districts, respondents had problems of skill in productionand utilization of forages. This study elucidates that, relevant development and research interventions such as management andutilization of improved forage production should be the future direction of research and development. Sustainable forage developmentand use for nature conservation and is becoming very important to be a livestock feed source if cut and carry system is regularly applied.

Abstract:
In Brazil ruminant production is based mainly on extensive systems in which forages are the most important, if not the only, source of nutrients. The quality of tropical forages declines seriously with advancing maturity and in extensive systems large amounts of forage commonly remain unused after grazing during the wet season (spring/summer). This unused forage could be harvested and sun-dried. During the dry season, there is a lack of feed on pastures and the hay produced from unused forages could provide a cheap alternative to concentrate supplements. The objective of this experiment was to evaluate three commercially available tropical forages as sheep feed in the Piracicaba river region of Sao Paulo State in Brazil.

Abstract:
Forage management underpins the viability of pastoral dairy systems. This review investigated recent developments in forage research and their potential to enable pastoral dairy systems to meet the challenges that will be faced over the next 10 years. Grazing management, complementary forages, pasture diversity, fertiliser use, chemical restriction, irrigation management and pasture breeding are considered. None of these areas of research are looking to increase production directly through increased inputs, but, rather, they aim to lift maximum potential production, defend against production decline or improve the efficiency of the resource base and inputs. Technology approaches consistently focus on improving efficiency, while genetic improvement or the use of complementary forages and species diversity aim to lift production. These approaches do not require additional labour to implement, but many will require an increase in skill level. Only a few areas will help address animal welfare (e.g. the use of selected complementary forages and novel endophytes) and only complementary forages will help address increased competition from non-dairy alternatives, by positively influencing the properties of milk. Overall, the diversity of activity and potential effects will provide managers of pastoral dairy systems with the best tools to respond to the production and environmental challenges they face over the next 10 years.

Abstract:
Intercropping of forage grasses and legumes can increase forage productivity and nutritive value; however, intercropping of corn with warm-season forages has not yet been studied in southeast U.S., thus requiring more information. The purpose of this study was to determine the yield and nutritive value potential of warm-season annual forages intercropped with corn (Zea mays L.) for silage production. Crabgrass [Digitaria sanguinalis (L.)] is considered a weed for corn production systems; however, our study shows that if crabgrass is interseeded with corn, it does not compete for resources and can maintain high corn yields. Forage mass for sunn hemp (Crotalaria juncea L.) was higher than that of cowpea [Vigna unguiculata (L.) Walp.] and crabgrass in 2016, due to a drought in spring and summer, giving sunn hemp a competitive advantage. Crude protein content was higher for cowpea as compared to crabgrass and sunn hemp, due to cowpea’s ability to maintain its vegetative stage and high N-fixation, when compared to crabgrass and sunn hemp. Despite differences in the mass of the intercropped forages, the total herbage mass of the produced silage did not differ in 2016 and 2017. Intercropped forages can be harvested and ensiled with corn for silage production or can be left with the corn residue after harvesting to be grazed on in integrated crop-livestock systems.

International Journal of Tropical Veterinary and Biomedical Research 1, no. 1 (May 1, 2016): 27–37. http://dx.doi.org/10.21157/ijtvbr.v1i1.5078.

Abstract:
Animal production can be more efficient and also sustainable if we reduce CH4 production from ruminal fermentation. One option is to find alternative forages that modify rumen fermentation. CH4 is not only harmful the environment but also means loss to the animals. All of the aspects of the issue is related to the condition of ruminant’s farm in Indonesia. Some other forages that are mainly fed as protein source to ruminants, are: cassava leaves, sweet potato leaves, soya bean leaves, tofu waste, leaves of Artocarpus heterophyllus, Musa paradisiaca L, Ipomea batatas. Roughage sources are hays of Panicum maximum, Pennisetum purpureum, and Setaria sphacelata and the concentrate sources mainly corn, rice bran and cassava waste, and corn cobs. However, there are very limited studies in finding alternative forages that can both increase animals productivity and also reduce CH4 production. Only forages relevant to Indonesia that have been studied in vitro is reviewed in this article, about its potential in reducing CH4 production from rumen fermentation. Even though some forages reduce CH4, it could negatively influence digestibility, hence less productivity. Some studies indicated that it was due to the fat content of the forage while others indicated that the concentration of the bioactive compounds such as condensed tannin influence the side effect of low CH4 ruminal production.

Abstract:
Abstract Fresh forages are the cheapest source of animal feed in world. Small grain cereals (SGC) are the most commonly used fresh forages or ensiled forage. Clovers are the perennial legumes that offer quality forage but their initial dry matter (DM) yield is low. Usually, SGC and clover are sown in mixtures to draw benefits from greater Cut-1 DM yield of cereals and biological nitrogen (N) fixation of clovers. However, mixtures are difficult to manage, compared to monoculture owing to differences in their growth pattern, temporal, spatial and physical requirements. In this review, SGC-clover mixtures are analyzed for their potential herbage DM yield and quality of the produce. Effect of various management factors on the productivity of forage mixtures are well documented. Decisions in managing mixtures, like choice of cereal and cutting time and how they affect the value of the final produce is reviewed. Besides decision, effect of relative proportion and spatial arrangement of intercrops is also deliberated. Special attention is paid to the competition between SGC and clovers and its impact on clover suppression in mixture. At the end conclusions are drawn to optimize production from mixtures.

Abstract:
Twenty alfalfa varieties grown in small plots on raised beds were evaluated for forage production beginning after planting in the fall of 1992. Data from eleven harvests were obtained in 1993 -1995, generally covering the summer months. No variety produced more forage than CUF 101 in each of the three years although Moapa had more tonnage than CUF 101 in two of the years. Moapa and Tillman (101.6% and 100.8% of CUF 101 respectively) had higher total production than CUF 101 during the study, although Tillman had the least production of varieties tested during the third year. The varieties Rio and WL 516 had least amounts of forage production over the three year period. Percentage bloom and plant height were very highly correlated from the July 1993 harvest. Total production from 1993-1994 were similar to the bloom and height of July 1993, as Tillman, Moapa and CUF 101 had the highest percentage bloom, while Rio and WL 516 had the least bloom. Cibola and CW 2981 had greater than 240, 000 crowns per acre following the 1994 season, followed by Tillman and Condor. WL 516, Madera, and ABI 9182 each had fewer than 180,000 crowns per acre. Tillman and Cibola had greater than 120,000 crowns /acre at the end of the third year; all other varieties had fewer. Hopperburn and associated yellows during the fall of 1995 was correlated with both crowns /acre and plant height, although crown numbers and height were not correlated.

Abstract:
Three experiments carried out in the southeast of Mexico (Yucatan) are reported. In the first, yield of P. purpureum increased from 3,760 to 14,526 kgDM/ha with age 6 weeks (young) and 28 weeks (mature). Maturity increased lignin from 43 to 108g/kgDM. Potential degradabilities of leaf and stem were 788g & 782g/kgDM with young, and 725 & 403g/kgDM with mature. Young yielded more potentially degradable DM (70 & 35kgDM/ha/d) than mature. In the second, molasses urea block (MUB) supplementation of bulls grazing during the dry season, did not improve the potential degradability of pasture (525g/kgDM). Estimated pasture intake was 68gDM/kgW0.75 /d, and measured rumen pool size of grazing bulls was 79 gDM/kgW 0.75. Intake of MUB was low (236gDM/d) and only increased rumen NH 3-N from 100 to 128mg/l. Availability of pasture was 255kg DM/animal. It is suggested that need of supplementation could be low if there is sufficient pasture to allow selective grazing. In the third, hay diets of young or mature P. purpureum were studied in six zebu (Bos indicus) bulls fed ad libitum. Intakes were, 91 and 44gDM/kgW0.75/d, digestibilities, 591 and 453g/kgDM, estimated energy intakes 768 and 307kJME/kgW0.75/d and Metabolizable Protein, 4.1 and 1.3g/kgW0.75/d with young and mature forages respectively. Forage maturity resulted in negative N balance (352 vs -113mgN/kgW0.75/d), decreased potential (756 vs 568g/kgDM) and fractional rate (0.07 vs 0.03%) of rumen DM degradation, but gave higher DM degradabilities of the non-soluble fraction (378 vs 283g/kgDM). Forage maturity reduced rumen outflow rates of liquid (0.09 vs 0.05%), and solid (0.038 vs 0.015%) phases, increasing mean retention times of digesta (22 vs 65h), and the rumen pool size (84 vs 120gDM/kgW0.75) and reduced the eating (380 vs 273min) and rumination daily times (433 vs 398min). The Purine Derivatives (PD) excretion in urine reflected differences between diets (651 vs 354mMol/kgW0.75/d). However, rumen Microbial N Supply estimated by the PD method was very low in comparison with estimates from digestibility and N balance measurements. It is suggested this effect could be explained by greater recycling of PD to the rumen and a lower endogenous excretion by zebu cattle.

La situation durable de volatilité des prix du pétrole est considérée à la fois comme une menace et un défi par l'industrie pétrolière. Au cours de cette crise, les compagnies pétrolières ont l’opportunité de se recentrer sur la recherche de solutions de production rentables, ce qui implique souvent l’apport des nouvelles technologies, en plus de l'amélioration des processus.Ce travail présente une avancée pour la synthèse d’une nouvelle génération de fluides de forage pétrolier sans surfactants/émulsifiants pour des applications dans le forage des puits profonds et ultra profonds. Cette nouvelle génération repose sur l’introduction des émulsions de Pickering dans la formulation des fluides de forage. Ces dernières sont des émulsions stabilisées uniquement par des particules solides (dans ce cas des particules de silice). Différents types de nano particules de silice de différentes hydrophobicités ont été utilisées pour stabiliser des fluides de forage de types huile-dans-eau et eau-dans-huile. Ces fluides ont été conçus pour être utilisés dans des conditions hostiles de température et de pression. Par conséquent, une caractérisation expérimentale de leur stabilité ainsi que de leurs propriétés rhéologiques sous ces conditions extrêmes étaient nécessaires. Au cours de ce travail, les profils rhéologiques de ces fluides reflétant leurs capacités de nettoyage du puits, leur coulabilité ainsi que leurs capacités à transporter les débris jusqu'à la surface, ont été établis. D’autre part, la stabilité électrique des émulsions ainsi que leur morphologie (distribution de taille des gouttelettes) ont été étudiées et une comparaison avec celles stabilisées par des agents tensioactifs a été établie. Les fluides ont été exposés à un processus de vieillissement qui permet d’étudier l'effet de l'environnement du réservoir hostile sur la stabilité et la rhéologie des nouveaux fluides préparés. Ces fluides de haute qualité se sont révélés très fiables, offrant une grande stabilité et une capacité à résister à des conditions extrêmes de réservoir. Ils représentent une nouvelle génération de fluides de forage ouvrant la voie à une exploitation optimisée de réservoirs profonds et ultra profonds
This enduring situation of volatile oil prices has been seen as a decline and a challenge at the same time for the oil and gas industry. It is during this slump that the oil and gas companies own the opportunity to focus on cost-effective production solutions, which very often means bringing new technologies and further improving processes.This work presents a novel frontier of surfactant-free drilling and completion fluids for deep and ultra-deep wells. This new generation of drilling fluids is based on the principle of Pickering emulsions (emulsions stabilized solely by solid nano particles). Hydrophobic and hydrophilic silica nano particles were used to stabilize Oil-Based Mud and Water-Based Mud. These fluids were designed to be used under hostile conditions of temperature and pressure. Therefore, a concrete characterization of their stability as well as their rheological properties under HTHP conditions was mandatory. Rheological profiles reflecting the flowability, hole cleaning capacity as well as cutting transport ability of the fluids were established. On the other hand, the electrical stability as well as the morphology (Droplet Size Distribution) of the emulsions were studied and compared with surfactant-stabilized drilling fluids. The fluids were submitted to an aging process allowing one to study the effect of hostile reservoir environment on the stability and rheology of the new fluids prepared.These high quality fluids were seen very reliable offering high stability as well as high capacity to withstand extreme reservoir conditions giving rise to a new generation of drilling fluids allowing breaking the frontiers of deep and ultra-deep reservoirs

Abstract:
The influence of microbial activity on the pattern of gas production and the possibility of developing a protocol for standardising the microbial activity of ruminal fluid were investigated (chapter 2). Firstly, ruminal fluid was diluted 1:2, 1:5, 1:9 and 1:20 (v/v) with buffer solution and the in vitro gas production from cellulose, glucose, hay and ryegrass studied. Gas production at 4, 24 and 120h were significantly decreased as the ratio of buffer solution to ruminal fluid increased. For each substrate, incubation with ruminal fluid diluted 1:2 (v/v) gave a higher (P<0.5) asymptotic value 'B', rate 'C' of gas production and lower lag time than when incubated in the 1:5, 1:9 and 1:20 dilutions. Secondly, the effect of frequency of ovine ruminal sampling on microbial activity and substrate fermentation was investigated. The bacterial DM, bacterial absorbance and blank's gas volume were significantly affected by daily sampling of ruminal fluid. Daily sampling of rumen fluid did not significantly affect the gas production degradability parameters (B,C and Lag) until the bacterial DM fell below 0.09 g DM/10 cm3 strained rumen fluid. Bacterial DM was strongly related to the absorbance of ruminal fluid (R2 = 0.99, p<0.001), suggesting that standardisation of the level of microbial activity between days and laboratory can be achieved by estimating the bacterial DM from the absorbance of the strained ruminal fluid. The influence of donor diet on initial microbial concentration and gas production degradability was studied (chapter 3). Bacterial DM, bacterial absorbance and the blanks' gas volume increased significantly as the ratio of sheep pellet to hay increased. The gas production degradability parameters (B, C and Lag) were also affected by changing the donor diet ratio of sheep pellets and hay. NDF digestibility of cellulose and hay was not significantly affected by donor diet. Bacterial DM was strongly related to the absorbance of ruminal fluid and the blanks' gas volume (R2 = 0.99, p<0.001). These results suggest that changing the ratio of concentrate to hay reduced the initial bacterial concentration and affected the gas production degradability parameters.

Abstract:
Two experiments were conducted to examine the use of peppermint leaves and cinnamon oil on methane production and apparent ruminal digestibility. In experiment 1, 12 jars were utilized in a completely randomized design to conduct three separate 24 hour batch culture experiments. The objective of the batch culture experiments was to examine the effects of the selected natural supplements on methane production. For the first batch culture, jars were randomly assigned to one of the following treatments: 1) control diet (CON); 2) CON plus the addition of peppermint leaves at 3% of the diet (PEP3); 3) CON plus the addition of peppermint leaves at 6% of the diet (PEP6); or 4) CON plus the addition of peppermint leaves at 12% of the diet (PEP12). The addition of the peppermint leaves increased (P = 0.004) oxygen and tended to increase (P = 0.10) nitrogen gas, but had no significant (P ≥ 0.15) effect on methane production. For the second batch culture, jars were randomly assigned to one of the folloiwng treatments: 1) control diet (CON); 2) CON plus the addition of cinnamon oil at 125 mg/L (CIN 125); 3) CON plus the addition of cinnamon oil at 250 mg/L (CIN250); or 4) CON plus the addition of cinnamon oil at 500 mg/L (CIN500). Cinnamon oil decreased (P = 0.002) methane production when added at 500 mg/L which also decreased (P = 0.001) total gas production compared to the other treatments. For the final batch culture, jars were randomly assigned to one of the following treatments: 1) control diet (CON); 2) CON plus the addition of peppermint leaves at 3% of the diet and cinnamon oil at 125 mg/L (3:125); 3) CON plus the addition of peppermint leaves at 3% of the diet and cinnamon oil at 250 mg/L (3:250); or 4) CON plus the addition of peppermint leaves at 6% of the diet and cinnamon oil at 125 mg/L (6:125). The addition of the peppermint leaves at 6% of the diet and cinnamon oil at 125 mg/L significantly decreased nitrogen (P = 0.05) and methane (P = 0.0001) gas production compared to CON and 3:250 treatment. Based on the results of the three batch cultures, experiment 2 utilized four dual-flow continuous fermenters in a Latin Square design to examine the effects of the selected natural supplements on apparent ruminal digestibility and ruminal characteristics. Fermenters were randomly assigned to one of the following treatments: 1) control diet (CON); 2) CON plus the addition of peppermint leaves at 3% of the diet (PEP3); 3) CON plus the addition of cinnamon oil at 500 mg/L (CIN500); or 4) CON plus the addition of peppermint leaves at 6% of the diet and cinnamon oil at 125 mg/L (COMBO). Treatments for experiment 2 had no effect (P ≥ 0.17) on apparent ruminal digestibility of nutrients. There was no significant difference (P ≥ 0.09) in total or individual VFA concentrations, suggesting that the use of peppermint leaves, cinnamon oil, or a combination of the two has no adverse effects on apparent ruminal digestibility. Feeding ruminants a natural supplement such as cinnamon oil, peppermint leaves, or a combination could potentially reduce GHG production when feeding a low-quality, forage based diet.

Full text
Abstract:
The evaluation of ammoniation of mature grass (1/3 Festuca sp, 1/3 Bromus and 1/3 Dactylis sp) as a basal diet for pregnant ewes and its effects on ruminal fermentation were studied. Ammoniation increased the forage dry matter intake (DMI), crude protein (CP), and gross energy digestibility. Ruminal pH and total volatile fatty acid were not affected by ammoniation (P>.05). Individual VFA concentrations were affected significantly. In a third experiment, ammoniated wheat straw was evaluated as a basal diet for wintering pregnant ewes. Ammoniated straw replaced grass hay in the diet. Dry matter intake was not different (P>.05). Final body weight total gain, and fleece weight were higher for controls (P.05). A fourth experiment evaluated how rehydrating wheat straws prior to ammoniation affected utilization by pregnant western white-face ewes. These treatments increased dry matter and crude protein intakes significantly (P.05). Lamb birth weight was not affected by treatment (P=.874) and fleece weight increased (P<.05). Nutritive value of 5 barley and 10 wheat straw varieties was evaluated for ruminants with the in situ technique. Fiesta and Kombar barley varieties exhibited the highest dry matter disappearance (P In a final study, nitrogen and energy balance was measured on lactating western white-face ewes during early and late lactation. Milk production was .683 and .711 L/d during early and late lactation. Efficiency of milk production was .429 and .338 milk L/kg DM consumed for early and late lactation, respectively. Nitrogen balance was positive during both stages of lactation. Milk gross energy and metabolizable energy were 15.13 and 14.16% for early and late lactation, respectively.

Well-educated (the zootechnician, cyberneticist, economist), he is the author of the unique project — variable norms of cattle feeding. It considers concrete conditions of economy, age, productivity, physiological state of animals, conditions of livestock keeping, a season of year, actual availability and quality of forages. After a semi-centennial period a factorial method again has been used by workings out of norms. Volkov’s original views on topical questions of a science and production are stated: about fodder analysis, effective means of grain processing, aminoadducts theory, the advisory help to farms of experimental base of Williams fodder institute, which stuff keeps in mind the creative work of well-known scientist Nikolai Pavlovich Volkov.

Abstract:
available in liquid, viscous, and powdered form on the market of the Russian Federation, there are certain difficulties with their dosage and uniform distribution in silage feeds. This is especially important for preservatives, which are used in small doses. Abroad, this issue is solved by using applicators which allow to make low doses of preservatives in the range of 125-250 ml/t uniformly [1]. In our country, to increase uniformity of preservatives distribution, water is usually added to a small amount of preservatives and they are applied by column centrifugal or diaphragm pumps at the rate of 3–5 l/t of silage raw material. It is not possible to apply preservatives in pure form with available metering pumps, as they cannot ensure uniformity and small doses of their application. In this regard, the installation for forage harvester for fine-dispersed application of preservatives by compressed air was developed in the Federal Williams Research Center of Forage Production & Agroecology. The results of laboratory studies are presented.

Abstract:
According to natural conditions, the non-black earth zone of Russia is the main region of concentration and specialization of meat and dairy cattle breeding, as well as pig and poultry breeding. In the near future, to ensure the food security of the region, including large industrial cities of Moscow, St. Petersburg and others, it will be necessary to produce about 20.8 million tons of milk, 4.6 million tons of meat, 16.6 billion eggs. To produce such a quantity of products, it is necessary to produce about 77 million tons of feed units, including 40 million voluminous and 37 million concentrated feed, including insurance funds and livestock re-production. The most important condition for the effective use of feed is provided with their protein (feed protein) [1–3]. Scientific and practical experience shows that in solving the problem of providing forage with protein, the leading role in the Non-Black Earth Zone belongs to cold and frost-resistant oilseeds, and above all rapeseed. In the Federal Williams Research Center of Forage Production & Agroecology, highly productive varieties have been created, technological bases for their cultivation have been developed, which ensure the seed productivity of spring forms up to 3.5 t/ha and winter crops - up to 6 t / ha of oilseeds. The development and implementation of the rapeseed sowing program in the zone will allow meeting the needs for vegetable oils, producing in the required volumes high-protein supplements in the form of oilcakes and meal for animal husbandry and poultry farming.

Abstract:
The Adaptation Resources for Agriculture Workbook was jointly developed by USDA Climate Hubs and NRCS to support producers, service providers, and educators to manage climate change. The workbook helps producers consider both short-term adaptive management actions (<5 yrs) and long-range strategic plans (5 to 20 yrs, subject to farm type). This workbook pro-motes adaptation through multiple resources including a “menu” of adaptation strategies/approaches and example tactics for cropping and forages, confined livestock, grazing, orchards and small fruit and vegetable production systems. Recent efforts by USDA Climate Hub NRCS Liaisons work to increase the number of examples, and have been documented as Case Studies. These Case Studies are of producers utilizing the 5-step process in the workbook to document their management choices to ameliorate climate change impacts to their operations.

Full text
Abstract:
La géothermie de faible profondeur avec des pompes à chaleur correspond à l’état actuel de la technique et est déjà largement répandue en Suisse. Au sein du futur système énergétique, la géothermie de moyenne à grande profondeur (1 à 6 km) devrait également jouer un rôle important, notamment en matière de fourniture de chaleur pour les bâtiments et les process industriels. Cette forme d’utilisation de la chaleur géothermique nécessite un sous-sol bien perméable, permettant à un fluide – généralement de l’eau – d’engranger la chaleur naturellement présente dans la roche et de la transporter jusqu’à la surface. Dans les roches sédimentaires, cette condition est généralement vérifiée du fait de la structure naturelle, tandis que dans les granites et les gneiss la perméabilité doit être générée artificiellement par injection d’eau. La chaleur ainsi récupérée augmente au fur et à mesure de la profondeur de forage : la température souterraine atteint environ 40°C à 1 km de profondeur et environ 100°C à 3 km de profondeur. Pour entraîner une turbine à vapeur en vue de produire de l’électricité, des températures supérieures à 100°C sont nécessaires. Étant donné que cela implique de forer à des profondeurs de 3 à 6 km, le risque de sismicité induite augmente en conséquence. Le sous-sol peut également servir à stocker de la chaleur ou des gaz, par exemple de l’hydrogène ou du méthane, ou encore à enfouir de façon permanente du CO2. À cet effet, les mêmes exigences que pour l’extraction de chaleur doivent être vérifiées et le réservoir doit en outre être surmonté d’une couche étanche, empêchant le gaz de s’échapper. Le projet conjoint « Énergie hydroélectrique et géothermique » du PNR « Énergie » était avant tout consacré à la question de savoir où en Suisse trouver des couches de sol appropriées, répondant de manière optimale aux exigences des différentes utilisations. Un deuxième grand axe de recherche concernait les mesures visant à réduire la sismicité induite par les forages profonds et les dommages aux structures qui en résultent. Par ailleurs, des modèles et des simulations ont été élaborés dans le but de mieux comprendre les processus souterrains qui interviennent dans la mise en œuvre et l’exploitation des ressources géothermiques. En résumé, les résultats de recherche montrent que la Suisse jouit de bonnes conditions pour l’utilisation de la géothermie de moyenne profondeur (1-3 km), tant pour le parc de bâtiments que pour les processus industriels. L’optimisme est également de mise en ce qui concerne le stockage saisonnier de chaleur et de gaz. Le potentiel de stockage définitif de CO2 dans des quantités pertinentes s’avère en revanche plutôt limité. Concernant la production d’électricité à partir de la chaleur issue de la géothermie profonde (> 3 km), il n’existe pas encore de certitude définitive quant à l’importance du potentiel économiquement exploitable du sous-sol. Des installations de démonstration exploitées industriellement sont absolument nécessaires à cet égard, afin de renforcer l’acceptation par la population et les investisseurs.
