Abstract:
The aim of this study was to find out the potential of agricultural and food industry wastes as the constituents of pig feed to improve pigs’ performance and to reduce the feeding cost. This study was conducted at Manokwari Regency, West Papua Province. The agricultural and food industry wastes were collected from two traditional market, and four small-scale food industries. All materials used as feed were proximately analyzed to determine their nutritional values. Average daily gain, feed consumption and feed coversion ratio were taken to determine the pigs performance. Feed cost using local market prices was estimated in knowing the ability of agricultural and food industry wastes to substitutes commercial feed. The result of this research indicates that the use of agricultural and food industries wastes as an alternative components of pigs’ feed to substitute the commercial feed do not reduce the pigs’ performance and production. Among three feeds that use of agricultural and food industry wastes, feed with the combination of 75% waste and 25% commercial feed had the best feed conversion ratio, namely 2.36. On the other hand, a mixture of 25% wastes and 75% commercial feed was the most economic one, and able to reduce the feeding cost of grower pig up to 48.00%.Key words: agricultural waste, food industry wastes, grower period, pig, feed

Abstract:
Radiometric control of products involved in the food chain is an important part of ongoing quality control of products related to food and feed. Content of primordial and anthropogenic radionuclides in some products directly determines their quality and further methods of usage. The most common way of intake of radionuclides in the human body is ingestion (80 %) through contaminated food and water. The foods of animal origin are largely represented in the human diet. Therefore radiation control of animal feeds and animal products will contribute to producing food for human nutrition without or with low risk for health. This paper presents the results obtained by gamma spectrometric analysis of mineral additives and mixtures for pig nutrition, from imported and domestic production. In most samples examined, activity levels of natural and radionuclides made during production were in accordance with the regulations. A certain number of tested mineral supplement samples had increased levels of activity of 238U (640- 2100 Bq/kg), which was not in accordance with applicable regulations.

Abstract:
The aim of this study was to determine the growth performance and carcass characteristics of growing-finishing pigs fed diets formulated on net energy (NE) basis with or without exogenous enzyme supplementation. Twenty-four pigs with an initial body weight (BW) of 25 kg were randomly allotted one of three treatments; a barley-based control diet formulated on a digestible energy (DE) basis (Diet A), control diet formulated on an NE basis (Diet B), and Diet B + multicarbohydrase enzyme (Diet C). Pigs were offered their respective diets in a 3-phase feeding program. Individual pig BW and feed disappearance were monitored once every 2 wk. Pigs were slaughtered when they reached 100 kg BW to determine carcass characteristics. During phase 1, an improvement (P = 0.02) in feed intake was observed in pigs fed Diet C compared with Diet B. In phase 3, pigs fed Diet B showed improvement in daily gain (P = 0.02) and feed efficiency (P = 0.05) compared with Diet A. Overall, when compared with control diet, pigs fed Diet B showed significant improvement in daily gain (P = 0.05) and feed efficiency (P = 0.01). In conclusion, the results indicate a better growth performance with diets formulated using the NE system. Moreover, enzyme supplementation had no effect on the overall performance of pigs.

Abstract:
Abstract Four commercial feed additives (CFA) were evaluated for efficacy in detoxifying deoxynivalenol (DON) in diets fed to 144 nursery pigs (BW 9.80+/- 0.5kg; 2 gilts, and 2 barrows/pen). Six test corn-soybean-meal based diets were: 1) positive control (PC), formulated with clean corn (NC), 2) formulated with contaminated corn (5.5 ppm DON), 3) NC with enzyme+binder1 (NCB1), 4) NC with clay (NCC), 5) NC with enzyme+binder2 (NCB2) and 6) NC with sodium metabisulfite (NCP). Diets were allocated to pens (n = 6) based on BW and fed ad-libitum for 4-wk; BW and feed intake were monitored weekly. At the end of wk-1, one pig/pen was euthanized for tissue collection. Assayed DON concentration for PC, NC, NCB1, NCC, NCB2 and NCP were 0.38, 2.3, 2.3, 2.3, 2.4, and 1.9 ppm, respectively. Diet effects were only observed for ADG and G:F in wk-1; pigs fed NCP had higher (P = 0.01) ADG compared to pigs fed NC and NCC, whilst pigs fed other diets had intermediate and similar ADG (P > 0.05) to pigs fed NC or NCC. Pigs fed NCP showed higher (P = 0.02) G:F relative to pigs fed other diets. The final BW was 31.3, 30.8, 30.4, 30.8, 31.1 and 32.2kg for PC, NC, NCB1, NCC, NCB2 and NCP-fed pigs, respectively. There were no (P > 0.05) diet effects on ADFI throughout the study. There was no (P > 0.05) diet effects on liver and spleen weight, jejunum morphology and concentration of plasma creatinine and urea. Ceca digesta concentration of citric acid was higher (P = 0.03) in pigs fed NCP than pigs fed NCB2. In conclusion, the lack of differences between PC and NC suggested pigs were tolerant to higher DON levels than the regulated dietary maximum of 1 ppm. Improved ADG and G:F due to NCP vs. NC was transient and was not linked to physiological responses.

Abstract:
One hundred and forty-four individually housed, entire male (Large White × Landrace) weaner pigs (28 days; 7.3 s.d. 0.1 kg) were individually housed and allocated to a 26-day feeding trial of 2 by 2 by 3 factorial design. The factors were (1) feed processing method (meal or steam pelleted), (2) feed form (dry or liquid), and (3) enzyme addition (basal diet, or basal diet plus 300 ppm xylanase or 100 ppm phytase). Five days post weaning, two pigs were removed from each treatment. The basal diet was formulated to be marginally adequate for pigs of this age, providing 13.8 MJ digestible energy (DE)/kg DM and 0.79 g available lysine/MJ DE. The diet contained 0.81% Ca, 0.44% non-phytate-P and 0.31% phytate-P. Compared with pigs fed dry diets, pigs fed liquid diets consumed less feed (70 ± 14.2 g/day; P < 0.05) had a lower daily gain (49 ± 12.5 g/day; P < 0.05) and as a consequence had a lower 26-day weight (1.1 ± 0.4 kg; P < 0.05). However, pigs fed liquid diets had a better feed conversion efficiency (adjusted to the same DM content as dry feed) than pigs on dry diets (1.16 versus 1.20 ± 0.02; P < 0.05). Steam pelleting the diets had no effect on feed intake or daily gain, but did improve feed conversion ratio (1.14 versus 1.22 ± 0.02; P < 0.05). The poorer growth on liquid feeds appeared to result from the feeding method imposing a degree of restriction on feed intake. Xylanase or phytase supplementation did not significantly affect non-starch polysaccharide levels in the diets or growth performance. Phytase supplementation increased (P < 0.05) daily intake, daily gain and 26-day weight, of pigs fed dry diets, but not those fed liquid diets. The results indicated that when diets were fed in liquid form, prior steam pelleting of the diets and enzyme supplementation did not provide additional benefit.

Abstract:
The continued genetic improvement for lean tissue growth rate and efficiency of pig production has allowed the liberal feeding of modern pigs without adverse effects on carcass quality or food conversion efficiency, even at heavy slaughter weights (Cole and Chadd, 1989; Webb, 1989). This genetic improvement has, however, been associated with a reduction in appetite so that the food intake of modern genotypes of pigs cannot be precisely assessed from the prediction equations established for the older and fatter genotype of pigs. The present experiment was designed to measure voluntary feed intake in order to facilitate the establishment of nutrient requirements and feeding strategies for modern pig genotypes.

Abstract:
The provision of creep feed to suckling pigs is considered to stimulate early food intake as well as health post weaning. However, Barnett et al. (1989) found no effects of creep feeding on post-weaning performance. Research by Pajor et al. (1986) indicated that there is a high variability in creep feed intake both among and within litters. This variability in creep feed intake is probably the main cause of disagreement on the effects of creep feed provision. The objective of the present study was to assess the effect of creep feed consumption on individual food intake characteristics and performance of group-housed weaned pigs. Chromic oxide was added to the creep feed to identify piglets that consumed food during the suckling period. In the piggery, IVOG®-feeding stations were used to measure individual food intake after weaning.

Abstract:
Abstract An experiment was conducted to test the hypothesis that feed flavor and feed sweetener improve growth performance of weanling pigs. One hundred twenty-eight pigs (5.97 ± 0.55 kg) were allotted to 4 treatments with 4 pigs per pen and 8 pen replicates per diet. A 3-phase feeding program was used. In all phases, a control diet was formulated based on corn and soybean meal, and 3 additional diets were formulated by adding feed flavor (500 mg/kg), feed sweetener (150 mg/kg), or their combination to the control diet. Fecal scores were visually assessed using a score from 1 to 5 (1 = normal feces to 5 = watery diarrhea). Experimental diets were fed to pigs for 6 wk. Data were analyzed using SAS with pen as the experimental unit. Diet was the fixed effect and replicate was the random effect. Results indicated that overall average daily feed intake (ADFI) was greater (P &lt; 0.05) and overall average daily gain (ADG) tended to be greater (P &lt; 0.10) for pigs fed the diet containing feed sweetener compared with pigs fed the control diet (Table 1). The observed improvements in ADG and ADFI also resulted in greater (P &lt; 0.05) final body weight for pigs fed the feed sweetener diet compared with pigs fed the control diet. Inclusion of feed flavor, feed sweetener, or the combination of feed flavor and sweetener in diets did not affect fecal scores of pigs, but inclusion of feed flavor resulted in reduced overall frequency of diarrhea (P = 0.05). In conclusion, supplementation of feed sweetener improved growth performance and feed flavor supplementation to diets ameliorated post-weaning diarrhea of weanling pigs from d 1 to 42.

Abstract:
The ability of pigs to consume sufficient nutrients for optimal performance is an important consideration in commercial pork production. Nutrient intake levels are directly related to voluntary feed intake. Voluntary feed intake in pigs is influenced by several factors including environmental conditions (e.g. thermal and social conditions), animal status (e.g., age and physiological status), and feed and feeding conditions (e.g. bulkiness of the feed and feed form). Although the individual effects of many of these factors on voluntary feed intake have been investigated and quantified, little has been done to characterize their interactive effects. Under commercial conditions, voluntary feed intake is clearly influenced by multiple factors at any one time. Thus, there is a need for a means to accurately quantify voluntary feed intake in pigs as affected by the different interacting factors. Until quantitative effects of these interactions are established it is suggested that feed intake be monitored. This can be achieved by obtaining feed intake on representative groups of pigs.

Abstract:
ABSTRACT An in vivo experiment was performed with pigs to study the inhibitory effect of fermented feed on the bacterial population of the gastrointestinal tract. Results demonstrated a significant positive correlation between pH and lactobacilli in the stomach contents of pigs in dry feed as well as in the stomach contents of pigs fed fermented feed. Furthermore, a significant positive correlation between the pH and the numbers of bacteria in the familyEnterobacteriaceae in the contents of the stomach of pigs fed dry feed was found. In the stomach contents of pigs fed fermented feed, a significant negative correlation was found between the concentration of the undissociated form of lactic acid and the numbers of Enterobacteriaceae. The numbers ofEnterobacteriaceae in the contents of the stomach, ileum, cecum, colon, and rectum of pigs fed fermented feed were significantly lower compared with the contents of the stomach, ileum, caecum, colon, and rectum of pigs fed dry feed. The numbers of total lactobacilli were significantly higher in the stomach contents of pigs fed fermented feed and in the ileum contents of one pig group fed fermented feed compared with the contents of pigs fed dry feed. However, the influence of lactobacilli on numbers of Enterobacteriaceae could not be demonstrated. It was concluded that fermented feed influences the bacterial ecology of the gastrointestinal tract and reduces the levels of Enterobacteriaceae in the different parts of the gastrointestinal tract.

Abstract:
A theory of growth and feed intake in the pig is proposed and the results of five experiments to test it are reported here. An attempt is first made to describe the potential growth in pigs, that is, growth under non-limiting conditions; the conditions needed to allow potential growth to be retained are then considered. Two ways of providing non-limiting feeding conditions are discussed: a single balanced feed and a set of feeds given as a choice. In addition, a model which predicts the voluntary feed intake of pigs is also developed and tested in experiments. The results from pigs offered single feeds in the first two experiments were consistent with the predictions of the model, which were that the rate of feed intake would increase as the protein content of the feeds was decreased. The size of the increase depended on the ability of the pig to lose heat. In these experiments, when pigs were offered a pair of feeds as a choice, a combination of which was non-limiting, the results suggested that this method cannot be successfully used to attain the potential growth of pigs. The diet selection results were characterised by a considerable variation in the diets selected by individual pigs, and only some pigs achieved what was estimated to be their potential rate of growth. It was suggested that pigs which failed to select a non-limiting diet did not have the necessary chance to choose. Experiment 3 evaluated a simple method of ensuring that pigs are given both the necessary choice, and the chance to choose. This was achieved by giving them the opportunity to sample the single feeds, which were to be offered as a choice, alone on alternate days for a short period of six days. Subsequently, pigs given a choice between two feeds were able to select a non-limiting diet. Experiment 4 incorporated the method established previously and consisted of a severe investigation into the rules of diet selection. It was concluded that pigs are able to avoid excess of nutrient, in this case protein, intake or to select the best possible diet in less favourable conditions, ie. a choice between two limiting feeds. The last experiment consisted of an extended test of the theory that a pig will select a diet which is a reflection of its degree of maturity, state and sex. Pigs made fat and delayed in growth in one period were subsequently given the opportunity to recover on a pair of feeds offered as a choice. The diets selected by the fat pigs satisfied their requirements for compensatory protein gain allowing only a slow rate of lipid gain. In addition, they met the different growth and fattening requirements by the two sexes. All these findings are discussed in relation to the use of choice-feeding as an independent test of other estimates of resource requirements, as a feeding technique when the potential growth of pigs is to be observed and as a help in predicting the feeding behaviour in pigs.

Abstract:
The purpose of this thesis was to investigate, in a series of four experiments, the factors that are important for the control and prediction of die voluntary food intake of growing pigs fed poor quality foods. The aim of experiments 1 and 2 was to provide a severe test of two current conceptual frameworks available for die understanding and prediction of food intake. Framework 1 assumes that intake will be that which allows genetic performance to be achieved. If this is not achieved then it is assumed to be because mere is a constraint to food intake (e.g. the bulk content of the food) operating. Framework 2 sees intake as being a consequence of a process of optimisation, such that biological efficiency (rate of net energy ingested per litre of oxygen consumed) is maximised. The experiments tested areas where the frameworks differed in their predictions of intake on poor quality foods. Experiment 1 tested the effect of ambient temperature on die intake of foods of differing bulk content, experiment 2 tested the effect of a period of reduced growth on die subsequent intake of foods of differing bulk content. The results of both experiments were in closer agreement with the predictions of framework 1. It was concluded that die results provided no evidence that the idea that intake on poor quality foods in young growing pigs is constrained by gut capacity should be rejected. Experiment 3 investigated die effect of giving foods of differing bulk content on die short term feeding behaviour (STFB) of growing pigs. It was expected that differences in bulk content between die foods would result in different levels of intake mat would be reflected as differences in STFB.

Full text
Abstract:
In order to describe the ontogeny of solid food consumption by pigs and determine its influence on weight gain, before and after an abrupt weaning at 4 weeks of age, individual feed consumption was measured using a technique that combined load cells and video images. Feed consumption varied greatly both between and within litters. Within litters, consumption was positively correlated with birth weight, and with early weight gains. This suggests that greater feed intake was typical of larger and more mature pigs rather than reflecting compensation for poor milk intake by smaller litter-mates. Within-litter differences in weight gain during the two weeks after weaning were positively correlated with birth weight but not correlated with pre-weaning creep feed intake. Creep feed intake appeared to contribute to pre-weaning gains and these were correlated with post-weaning gains; however a more direct affect on post-weaning gain could not be detected.

Abstract:

Hampshire crosses of different genotype and sex were used to investigate the effects of rearing system, feed and handling on sensory quality, consumer preference and cooking loss. A selected and trained panel carried out descriptive tests. Two preference tests were carrieout by, in each case, 200 consumers.

The genotype had a major effect on sensory quality in all four studies irrespective of rearing system, feed and sex. In three of the four studies pork from RN¯ carriers scored higher for juicines, tenderness, acidulous taste and meat taste intensity.

Sex showed contradictory effects on sensory quality, while rearing system and feed had minor effects on sensory properties of pork.

Hams (M. biceps femoris) from pigs reared outdoors scored lower for juiciness and acidulous taste than hams from pigs reared indoors. Loins from pigs organically reared (KRAV) scored lower for juiciness and higher for crumbliness than ones from pigs conventionallreared.

Loins (M. longissimus dorsi) aged four days from conventionally fed pigs were juicier than ones from silage-fed pigs. When loins were aged eight days there was no difference in juicines while acidulous taste became weaker and tenderness and meat taste intensity increased.

In the case of loins stored frozen one year, those from silage-fed pigs scored higher for acidulous taste and off-flavour than those from conventionally fed pigs.

Cooking, thawing and total loss data showed minor and contradictory differences between genotypes, sexes, rearing systems and feeding regimes.

Organically and conventionally produced loins were equally liked and loins from RN¯ carrier pigs were preferred to loins from non-carriers.

Abstract:
Three experiments were conducted to assess the efficacy of including selected feed additives in the diet of weaning and grow-finish pigs. Experiment 1 utilized 24 crossbred grow-finish pigs and measured the effect of added EHY on DM, N, and energy digestibility. There were no differences in DM, Energy, and N digestibility between diets 1 through 4. Experiment 2 utilized a total of 36 crossbred pigs [18 barrows, 18 gilts] in order to determine if preference would be shown when presented with naturally-contaminated corn. There were three dietary comparisons, Control vs Diet 2 (Comparison 1), Control vs Diet 4 (Comparison 2), and Diet 2 vs Diet 4 (Comparison 3). A preference was shown for the control diet over Diet 2, as well as for the control diet over Diet 4. Experiment 3 utilized a total of 24 crossbred pigs [12 barrows, 12 gilts] in order to measure the effect of contaminated corn on performance and DM, energy, and N digestibility. DM, energy, and N digestibility were affected by corn quality.

To evaluate the effect of chromium yeast (CY) and ractopamine (RAC) on performance, carcass characteristics, meat quality, and blood, an experiment was conducted with 96 commercial castrated crossbred pigs with an average initial body weight of 75.07 ± 3.9 kg. Animals were distributed in a randomized-block experimental design with six treatments, eight blocks and two animals per stall. The treatments consisted of feeding plans (FP) in two phases: from 0 to 14 days; and from 14 to 42 days of age, respectively, composed of diets: Control/Control (CD/CD); Chromium yeast/Amino acids (CY/AA); Chromium yeast/Amino acids + Ractopamine (CY/AA+RAC); Control /Chromium yeast (CD/CY); Control/Amino acids + Chromium Yeast (CD/AA+CY); and Chromium Yeast/Amino Acids + Ractopamine + Chromium Yeast (CY/AA+RAC/CY). The greatest final weight and daily weight gain (P<0.0001) were observed in the animals subjected to CY/AA+RAC+CY. Feeding plan CY/AA+RAC provided an intermediate final weight and daily weight gain, similar to those obtained with the use of CY/AA+RAC+CY, CD/CD, CY/AA and CD/CY, but greater than CD/AA+CY. The pigs fed CY/AA+RAC+CY showed a greater fasted body weight (FW) (P<0.0001) as compared with CD/CD, CY/AA, CD/CY and CD/AA+CY. Feeding plan CY/AA+RAC provided an intermediate FW, similar to that obtained with the use of CY/AA+RAC+CY, CD/CD, CY/AA, but greater than CD/AA+CY. The evaluated FP did not influence (P>0.05) daily feed intake. The best feed-conversion results (P<0.0001) were obtained with CY/AA+RAC+CY and CY/AA+RAC. A larger loin-eye area was found in pigs subjected to CY/AA+RAC as compared with the use of CD/CY. The greatest muscle fiber diameter (P<0.011) was found in the pigs subjected to CY/AA+RAC+CY and CD/CY, which were higher than the group fed CD/CD. The liquid loss due to thawing determined in the meat of the pigs subjected to CD/CD was lower (P<0.009) than that observed with the use of CY/AA+RAC. A higher value of Cie a* was determined in the meat of the animals subjected to CY/AA+RAC as compared with CY/AA+ RAC+ CY. The pigs fed CY/AA+ RAC+ CY had a brighter meat than the other animals. The lowest TBARS concentration (P<.001) was observed in the meat of pigs subjected to CY/AA+RAC in relation to the group that consumed CY/AA. A greater concentration of myristic fatty acid (FA) (14:0) was found in the groups that received CY/AA+RAC as compared with the group fed CY/AA+RAC+CY. The pigs that received the FP with CY/AA+RAC+CY and CD/CY displayed greater levels of linoleic FA (18:2n6) in the longissimus dorsi muscle, as compared with the pigs fed CY/AA. The feeding plans did not affect the evaluated blood parameters (P>0.05). The use of chromium yeast and ractopamine or alone promoted positive alterations in the development of muscle cells in the pigs and in the meat quality, which should be considered when this mineral is used. The association of chromium yeast with ractopamine revealed improvements in the animal performance.
Para avaliar o efeito do cromo levedura (CrL) e ractopamina (RAC) em rações sobre o desempenho, características da carcaça, qualidade de carne e variáveis sanguíneas, foi realizado um experimento com 96 suínos machos castrados híbridos comerciais com peso corporal médio inicial de 75,07 ± 3,9 kg, distribuídos em delineamento experimental em blocos casualizados, com seis tratamentos, oito blocos e dois animais por baia. Os tratamentos foram constituídos de planos nutricionais (PN) em dois períodos consecutivos: período 1 de 0 a 14 dias e o período 2 de 14 a 42 dias, respectivamente, compostos pelas rações: Controle/Ração Controle (RC/RC); Cromo levedura/Aminoácidos (CrL/AA); Cromo Levedura/Aminoácidos + Ractopamina (CrL/AA+RAC); Controle/Cromo Levedura (RC/CrL); Ração Controle/Aminoácidos + Cromo Levedura (RC/AA+CrL) e Cromo Levedura/Aminoácidos+Ractopamina+Cromo Levedura (CrL/AA+RAC+CrL). Maior peso final (PF) e ganho de peso diário (GPD) (P<0,001) foi observado para os suínos submetidos ao PN CrL/AA+RAC+CrL. O PN CrL/AA+RAC proporcionou PF e GPD intermediário, semelhante aos obtidos com o uso de CrL/AA+RAC+CrL, RC/RC, CrL/AA e RC/CrL e superior ao PN RC/AA+CrL. Os suínos alimentados com o PN CrL/AA+RAC+CrL apresentaram maior peso de jejum (PJ) (P<0,0001) quando comparados aos PN RC/RC, CrL/AA, RC/CrL e RC/AA+CrL. O PN CrL/AA+RAC promoveu PJ intermediário, semelhante ao obtido com o uso de CrL/AA+RAC+CrL, RC/RC, CrL/AA e superior ao RC/AA+CrL. Os PN avaliados não influenciaram (P > 0,05) o consumo diário de ração. Os melhores resultados de conversão alimentar (P<0,001) foram obtidos com os PN CrL/AA+RAC+CrL e CrL/AA+RAC. Maior área de olho de lombo foi determinada nos suínos submetidos ao PN CrL/AA+RAC quando comparado a utilização de RC/CrL. Maior diâmetro da fibra muscular (P<0,011) foi verificado nos suínos submetidos aos PN CrL/AA+RAC+CrL e RC/CrL sendo estes superiores ao grupo consumindo RC/RC. A perda líquida por descongelamento determinada na carne dos suínos submetidos ao PN RC/RC foi inferior (P<0,009) a obtida com o uso do PN CrL/AA+RAC. Maior valor Cie a* foi determinado na carne dos animais submetidos ao PN CrL/AA+RAC quando comparado ao PN CrL/AA+ RAC+ CrL. Os suínos submetidos ao PN CrL/AA+ RAC+ CrL apresentaram maior tonalidade na carne frente aos demais animais. Menor concentração de TBARS (P<0,001) foi verificada na carne dos suínos submetidos ao PN CrL/AA+RAC frente ao grupo consumindo ração CrL/AA. Maior teor de ácido graxo (AG) mirístico (14:0) foi verificado para os suínos submetidos ao PN CrL/AA+RAC quando comparado ao grupo CrL/AA+RAC+CrL. Os suínos que receberam os PN com CrL/AA+RAC+CrL e RC/CrL apresentaram maior concentração de AG linolêico (18:2n6) no músculo Longissimus dorsi, frente aos suínos do PN CrL/AA. Os PN não influenciaram as variáveis sanguíneas avaliadas (P>0,05). O uso de cromo levedura e ractopamina promoveram alterações positivas sobre o desenvolvimento de células musculares nos suínos e na qualidade da carne que devem ser consideradas quando da utilização do mineral e o uso em associação a ractopamina revelou melhorias sobre o desempenho dos animais.

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.
