Abstract:
Copper (Cu) status of cattle raised in different soil zones of Saskatchewan was examined with emphasis on the relation between liver Cu concentration in pregnant cows, stage of pregnancy and fetal liver Cu status. Whole fetuses and livers from adult animals were obtained during routine slaughter operation at a local packing plant. Twenty percent of steers, 54% of pregnant cows, 52% of heifers and 77% of nonpregnant cows had liver Cu levels less than 25 mg kg−1 dry matter (DM). Hypocuprosis was most marked in cattle originating from northern regions of Saskatchewan. Fetal liver Cu concentration depended on the dam liver Cu concentration and on stage of pregnancy and could be represented as: Fetal liver Cu concentration (mg kg−1 DM) = 217.5 + 0.023 [(age of fetus (days) × dam liver Cu concentraiton (mg kg−1 DM)]. During gestation the level of Cu progressively increased in the fetal liver and decreased in maternal liver. Liver Cu levels of fetuses from dams with liver Cu greater than 25 mg kg−1 DM were higher (P < 0.05) than those in fetuses from dams with liver Cu levels lower than 25 mg kg−1 DM. Dam liver Cu status did not influence fetal liver, kidney, heart and brain weights or the Cu concentration of fetal kidney, heart or brain. The magnitude of hypocuprosis in cattle in Saskatchewan is extensive and emphasizes the importance of adequate Cu nutrition in pregnant cattle with respect to maintaining acceptable fetal Cu status.

Abstract:
Hepatic copper (Cu) storage was determined in grazing sheep and cattle supplemented with copper oxide powder, oxidized Cu particles or Cu-calcium EDTA. Cu storage was significantly increased when particles or the EDTA complex were given, but responses in hepatic Cu concentration were small in animals given copper oxide powder. Sheep dosed with copper oxide particles retained particles in the abomasum at 44 days from dosing, but those given copper oxide powder did not retain measurable quantities in the abomasum and excreted about half the dose in the faeces within 4 days of administration.

Abstract:
Abstract Trace minerals (TM) are required for many biochemical processes and support optimal animal growth. However, as animal genetics and feed technologies in the beef industry have advanced, our understanding of the TM requirements of modern cattle has lagged. Recently, Zn and Cu have emerged as potential targets for better understanding the interaction between nutrition and growth-promoting technologies like anabolic implants and β-agonists (BA). Both Zn and Cu are phosphodiesterase inhibitors, potentially maintaining cAMP concentrations, potentiating the BA signal. Zinc supplementation well above national recommendations can improve ADG or HCW in finishing cattle during the BA feeding period, and N retention is increased by both Zn and BA supplementation, suggesting a major role for Zn is in protein accretion. Interestingly, Cu status of feedlot steers appears to affect ADG during the BA period, where steers with moderate liver Cu and 10 mg Cu/kg diet DM gaining more than steers with high or low Cu status. Anabolic implants likely improve growth through altering protein deposition, degradation and satellite cell proliferation, processes that can be linked to Cu and Zn metalloproteins. Implanting cattle decreases both plasma and liver Zn, and heifers receiving a long-lasting implant had greater HCW when supplemented with 100 mg Zn/kg DM when compared with 30 mg Zn/kg DM. It is apparent Cu status and supplementation also affect the response to hormone implants. Steers supplemented with 20 mg Cu/kg DM had greater liver Cu concentrations and a lesser response to an implant than steers supplemented with 10 mg Cu/kg DM. Current state of knowledge suggests TM status and diet concentrations can impact the response to growth promoting technologies. Much remains to be learned about cattle requirements for dietary TM, and the appropriate TM concentrations to optimize feedlot cattle performance.

Abstract:
The nutrient content of diets consumed, using a bite count technique, and the performance of beef cows and their calves grazing spruce and pine clearcuts in the southern interior rangelands of British Columbia on continuously and rotationally grazed pasture systems were evaluated in a 3- to 5-yr study. Forage species and plant parts ingested by cows were collected by hand clipping to simulate the diet. Nutrient composition of each sample forage was determined chemically and the nutrient levels of cattle diets were estimated from the bite counts of forages consumed and the chemical composition of the clipped samples. Dietary deficiencies, based on estimates of dietary intake of cows and chemical composition of samples, were noted for protein and phosphorus during August and September (rotational grazing); sodium during September; iodine, copper and zinc throughout the grazing season with the exception of zinc in the September diet of rotationally grazed cows. Selenium was adequate to excessive in the diet. Cow diets consisted of from 50 to 72% grass, from 23 to 42% forbs and from 4 to 20% shrubs. The diversity of diet components maintained nutrient levels of the diet above those provided by grass alone. Weight gains of cows and calves were obtained at monthly intervals for 3 yr and seasonally for 5 yr. There were no significant differences in cow performance among years or between grazing treatments. Cows gained an average of 0.22 kg d−1 over a 90-d grazing period. Average daily gains of cows decreased from 0.55 kg in July to −0.21 kg in September. Calf gains were significantly different between treatments over 5 yr. Calf gains averaged 0.92 kg−1 d on the continuously grazed pastures vs. 0.83 kg d−1 on those rotationally grazed. Total beef production of saleable beef (calves) under the continuous and rotational grazing system was 72.7 kg ha−1 and 65.3 kg ha−1, respectively.

Abstract:
ABSTRACT: Copper is an essential micromineral in animal feed; however, when consumed in excess, it can cause liver necrosis, hemolytic crisis, hemoglobinuric nephrosis and death in cattle. Although uncommon in this species, copper poisoning occurs as a result of exacerbated supplementation, deficiency of antagonist microminerals, or previous liver lesions. An outbreak of chronic copper poisoning is reported in semi-confined cattle after supplementation with 50 mg/Kg of dry matter copper. The cattle showed clinical signs characterized by anorexia, motor incoordination, loss of balance, jaundice, brownish or black urine, diarrhea and death, or were found dead, 10 to 302 days after consumption. Of the 35 cattle that died, 20 underwent necropsy, whose frequent findings were jaundice, enlarged liver with evident lobular pattern, black kidneys, and urinary bladder with brownish to blackish content. Microscopically, the liver showed vacuolar degeneration and/or zonal hepatocellular centrilobular or paracentral coagulative necrosis, in addition to cholestasis, mild periacinal fibrosis, apoptotic bodies, and mild to moderate mononuclear inflammation. Degeneration and necrosis of the tubular epithelium and intratubular hemoglobin cylinders were observed in the kidneys. Copper levels in the liver and kidneys ranged from 5,901.24 to 28,373.14 μmol/kg and from 303.72 to 14,021 μmol/kg, respectively. In conclusion, copper poisoning due to excessive nutritional supplementation is an important cause of jaundice, hemoglobinuria, and death in semi-confined cattle.

Abstract:
Sewage sludge contains a range of essential and non-essential elements for livestock nutrition, many of which are toxic at elevated levels. Where sludge is applied to the surface of pasture regularly, contaminants principally heavy metals will accumulate in the surface layer (Davis et al 1988), and may represent a potential health hazard for grazing animals through the direct ingestion of contaminated soil much greater than that from plant uptake. Whilst it is known that soil ingestion can supplement mineral intake with benefits to grazing animals in some situations, the potentially toxic effects of ingesting soil from heavily sludged pastures are of principal concern (Stark 1988). Bearing in mind the strategic importance of grassland for sludge disposal, it must be demonstrated whether existing soil metals limits (DoE 1988) will adequately protect grazing animals. The principal objective of the trial was to study animal growth performance as well as mineral balance from a diet with elevated copper levels derived from a sludge treated soil. Lambs were used for their greater sensitivity to copper than cattle, and the length of the trial simulated the normal finishing period of five months for lambs on pasture.

Abstract:
Dermatophilosis is an economically important disease prevalent in Nigeria. It is a skin disease that affects mainly cattle, sheep and horses, but also goats, dogs and cats, many wild mammals, reptiles and, occasionally, humans. The disease is caused by the bacterium Dermatophilus congolensis, which is a member of the order Actinomycetales with a great potential for causing severe economic losses in cattle. In recent time, there have been cases of ineffective treatment to this disease in Nigeria. The various control strategies for Dermatophilosis are discussed in this paper. Recommendations for control of Dermatophilosis in Nigeria on short term include ecto-parasite control by regular use of insecticide/acaricide in dips with added 0.03% copper sulphate or 1% solution of alum (potassium aluminium sulphate) spray. Infected animals should be isolated and treated with effective antibiotics or culled, while use of barb wire in the construction of cattle paddocks should be discouraged. Adequate nutrition should be provided for the animals all year round. Long term measures include gradual genetic upgrading of susceptible breeds with fairly resistant ones such as N’dama, Muturu and Keteku.

Abstract:
The nature of the mineral supply of certain biogeochemical provinces and their correlative interactions within biological organisms determine the degree of development of immunosuppressive states in animals. So we studied the level of minerals in the samples of hair and blood in cattle in the «mother-offspring» system and established the nature of the correlation of cobalt, zinc, iron and copper. It has been proven that low levels of cobalt (cows - 429.30 ± 4.05 nmol/l and calves - 430.80 ± 5.60 nmol / L) and zinc (cows - 7.21 ± 0.20 pmol/l and calves - 7.60 ± 0.15 pmol/l) against the threshold values of iron (cows - 17.90 ± 1.30 pmol/l and calves - 18.40 ± 1.80 pmol/l) and copper (cows - 13.90 ± 1.80 pmol/l and calves - 14.08 ± 1.05 pmol/l) in the blood caused hematopoietic function impairment and led to the development of mild hypochromic anemia (erythrocytes: cows - 6.01 ± 0.40x1012/l and calves - 6.36±0.50x1012/l) in animals in the «mother-offspring» system. In addition, metabolic disorders caused by nutritional deficiency of zinc contributed to a decrease in the synthesis of alkaline phosphatase (cows - 87.90 ± 5.10 U/l and calves - 126.80±4.02 U/l), exacerbating the disorder of erythropoietic function of red bone animal brain. A long-term imbalance of copper and zinc in the nutrient substrates of the studied animals was revealed, as evidenced by the results of a mineralogram of hairline samples (copper: cows - 13.910 ± 0.67 mg/kg and calves - 12.609 ± 0.70 mg/kg; zinc: cows - 57.960 ± 0.90 mg/kg and calves 60.315 ± 0.99 mg/kg), which ultimately led to a deficiency of zinc in the body, leading to the development of an immunosuppressive state (Ig M: cows - 0.99 ± 0.15 mg/ml and calves - 1.64 ± 0.05 mg/ml; Ig A: cows - 0.30 ± 0.05 mg/ml and calves - 2.05 ± 0.10 mg/ml).

Abstract:
Managing the mineral nutrition of free-range grazing livestock can be challenging. On farms where grazing animals are infrequently yarded, there are limited opportunities to administer trace element supplements via feeds and concentrates. In New Zealand, where the majority of sheep, cattle, and deer graze pasture year round, inadequate intake of cobalt, copper, iodine and selenium is prevalent. Scientists and farmers have developed efficient strategies to monitor and treat these dietary deficiencies. Supplementation methods suited to grazing livestock include long-acting injections, slow-release intraruminal boluses, trace element-amended fertilisers, and reticulated water supplies on dairy farms.

Abstract:
Abstract Optimal mineral nutrition is required for cattle reproduction, immune function, and structural development. Formal evaluation of the current mineral status of California beef cattle is currently lacking. In 2017, a survey was initiated that evaluated a panel of 10 different minerals in 14 counties across California. Samples were collected from 555 cattle at 50 different ranches. Region of the state significantly affected herd mineral status. Herd use of supplements was also significant, and increased most blood levels of the mineral(s) targeted for supplementation. Forage source was idiosyncratic on its effect of mineral status. Previous blood survey data showed selenium to be widely deficient in California cattle in the 1970s and 1980s, but in this case, it was generally adequate in all areas of California. This indicates a good producer understanding of where supplementation is needed. Copper deficiency was more widespread in the southern region when compared with further north. Zinc deficiency was seen ubiquitously statewide, with 36% of animals being deficient. Manganese has been largely ignored in California. This study is the first known documentation of manganese levels in the state. Sampling found 92% of cattle fell below critical manganese levels. However, further research to better define manganese critical levels is probably warranted. The status of other minerals is presented.

Abstract:
The effect of a low-Cu diet supplied to gilts during pregnancy and early lactation on dams and their offspring was obtained in seven pairs of first littermate gilts. They were housed in stainless steel metabolism cages in a controlled environment and fed semi-purified diets containing either 2.13 or 12.25 ppm Cu from 30 days of gestation through two weeks of lactation. Feed intake was restricted to 2 kg/day during pregnancy and 4 kg/day in the first two weeks of lactation. Reproductive performance of gilts was measured. Balance studies were conducted at 30, 60 and 100 days of gestation. Mineral levels in the plasma of gilts and piglets, and in colostrum and milk were determined. The low-Cu diet did not affect (p $>$ 0.05) weight changes during pregnancy. The duration of parturition was shorter for low-Cu than for control gilts (3.19h vs 5.71h, p 0.05). Low-Cu gilts had lower plasma Cu in early- and mid-gestation and farrowed piglets with lower plasma Cu and higher plasma Zn concentrations (p 0.05). Plasma Cu and Fe levels of newborn piglets were lower than those of their dams (p 0.05). Low-Cu gilts had lower Cu and higher Zn content in colostrum and also lower Cu in milk than control gilts (p 0.05). Colostrum was richer in Cu and Zn than milk (p 0.05). Higher dry matter digestibility was observed in low-Cu gilts during early gestation (p 0.05). Compared to control gilts, the low-Cu gilts tended to have higher Cu and Zn retention which was achieved by reduction of fecal Cu and Zn excretion. Utilization of minerals appeared to increase as pregnancy progressed.

Abstract:
Experiments were conducted to determine effects of feeding whole cottonseed (WCS), expander solvent cottonseed meal (CSM), or a combination of these, as well as other factors on blood gossypol concentrations in cattle. In an 84 d trial, lactating cows were fed zero, 900 or 1800 ppm total gossypol (TG) in diets from WCS and/or CSM. Plasma gossypol (PG) in cows receiving 1800 ppm TG plateaued at 3.28 μg/ml after 28 d. However, by 28 d, erythrocyte fragility increased for cows receiving WCS diets. Plasma chemistry, vitamin A, body temperatures, and respiration rates were within normal ranges. Serum vitamin E levels increased with cottonseed in diets. Milk yield and FCM higher (P < 0.05) for cows fed 13.5% WCS and 7% CSM diet than controls. Feed efficiency and milk fat and protein percentages were not influenced by diets. In another study, young Holstein steers were fed diets during five consecutive treatment periods of 28 d each. The following was shown: (1) A basal diet with 15% Upland WCS resulted in average TG intakes of 9.08 g/d. (2) When varying concentrations of dietary iron (5 treatments) were fed with 15% WCS, PG and plasma total gossypol response (PG/TG intake) decreased as iron in diets increased. (3) Five diets with 15% cottonseed in the whole, cracked, roasted, roasted and cracked, or extruded forms showed that roasting or excluding WCS reduced FG in seed up to 86%. The PG concentration was higher (P < 0.05) for the whole and cracked diets, but plasma total gossypol response (PTGR) increased over controls for the cracked and roasted treatments. (4) When varying amounts of WCS and CSM (6 treatments) were fed up to 14 and 9% of the diet, respectively, PG concentration was higher (P for diets with 14% than 7% WCS. The PTGR was not affected by CSM supplementation for the 7% WCS treatments. (5) When feeding of four diets with 15% cottonseed as whole Upland, cracked Upland, whole Pima, or cracked Pima seed, PG and PTGR were higher for the Pima than Upland diets. Performance for the 28 d periods was not altered by treatments.

Abstract:
Four studies were conducted using high water soluble carbohydrate (WSC), sweet (SM) and low WSC, regular (RM) pearl millet and high WSC (SS) and low WSC (RS) sorghum cultivars. The first and the second studies evaluated the chemical composition and ensiling characteristics of those cultivars. Millet cultivar had no effect on pH. SM silage contained less neutral and acid detergent fiber than RM silage. SS cultivar had less pH than RS cultivar at any ensiling period. RS silage contained greater acid detergent lignin and less non protein nitrogen than SS silage. The third and the fourth studies investigated the feeding value of SM and SS silages. Cows fed SM silage produced milk with greater fat concentration, energy corrected milk, 4% fat corrected milk, and solid corrected milk yield than cows fed corn silage. Milk fat was greater, while milk yield and lactose concentration were less for cows fed SS silage than cows fed alfalfa silage. In conclusion, there is a good potential for pearl millet silage as a source of forage for dairy cows. Further investigations are required to optimize the feeding value of sorghum silage.
Quatre études ont été conduites utilisant deux variétés de millet perlé [i.e. riches en glucides solubles (GS) (MS) et pauvre en GS (MR)] ainsi que deux variétés de sorgho [i.e. riches en GS (SS) et pauvre en GS (SR)]. Les première et deuxième études évaluèrent la composition chimique et les caractéristiques d'ensilage des différentes variétés. La variété de millet n'eut pas d'effet sur le pH. L'ensilage de MS contenait moins de fibre NDF et ADF que l'ensilage de MR. La variété de SS avait un pH inférieur au SR à tout moment lors de la période d'ensilage. L'ensilage de SR contenait une quantité supérieure de lignine et moins d'azote non protéique que l'ensilage de SS. Les troisième et quatrième études investiguèrent la valeur nutritive des ensilages de MS et SS. Les vaches soignées à l'ensilage de MS ont produit du lait plus concentré en gras, énergie du lait corrigée, 4% gras du lait corrigé et rendement en solides du lait corrigé que les vaches soignées à l'ensilage de maïs. La concentration en gras du lait était la même tandis que le rendement en lait et la concentration en lactose furent inférieurs pour les vaches soignées à l'ensilage de SS comparativement à celle soignées à l'ensilage de luzerne. En conclusion, il y a un grand potentiel pour l'ensilage de millet perlé en tant que source de fourrage pour les vaches laitières. D'autres études seraient nécessaires pour optimiser les valeurs nutritives de l'ensilage de sorgho.

Two trials were conducted to evaluate the effects of crude glycerin in feedlot cattle. The objectives of this research were to determine the effects of crude glycerin on animal performance, carcass characteristics, ruminal metabolism, and diet digestibility when fed in steam-flaked corn finishing diets. Trial one utilized crossbred heifers (n = 373) fed finishing diets containing 0, 2, 4, 8, 12, or 16% crude glycerin. Feeding heifers crude glycerin at 8% or less of the diet resulted in improvements in body weight gain and feed efficiency. Dry matter intake decreased linearly (P < 0.001) when glycerin was included at increasing levels from 0 to 16%. Average daily gains of heifers fed crude glycerin increased when glycerin was fed at 2, 4, or 8% of diet DM, but reductions in ADG were noted when glycerin increased to 12 or 16% (linear, P = 0.013; quadratic, P = 0.010). Feeding glycerin had a quadratic effect on G:F, and was optimal when fed at 2% of DM (P = 0.46). Hot carcass weights increased when glycerin was fed at 2, 4, and 8% of the diet, but decreases in HCW were observed with 12 and 16% crude glycerin (linear, P = 0.009; quadratic, P = 0.006). Low concentrations of glycerin can be fed without negatively impacting animal performances. Trial two consisted of a 3 × 3 Latin Square and utilized cannulated crossbred steers (n = 9) fed finishing diets containing 0, 2, or 4% crude glycerin. Apparent total tract digestibilities of DM, OM, starch, CP, and crude fat were unaffected by the addition of glycerin at 0, 2, or 4% of cannulated steer diets (linear, P > 0.51). Apparent total tract digestibilities of NDF tended to decrease as glycerin concentrations increased to 2 and 4% (linear, P <0.13). Ruminal pH increased as glycerin concentrations increased (linear, P < 0.05), and concentrations of butyrate and valerate decreased (linear, P < 0.03). Acetate production also tended to decrease when glycerin increased from 0 to 2 or 4% of the diet (linear, P =0.06). Collectively, these results suggest that glycerin may negatively influence fiber digestion.

Abstract:
Dairy cattle breeding is one of the main suppliers of protein and animal fat, it is one of the most important branches of agriculture and plays a primary role in providing adequate nutrition for the population. During the purposeful work on harmonization of the national regulatory framework with international legislation, special attention is paid to scientific developments in the way of full implementation of Russian livestock production in the global trading system. The recommendations of the International Committee for Registration of Animals (ICAR) (Global Standard…, 2017; Trukhachev et al., 2017) are the methodological basis for the introduction of the generally accepted organizational principles for the recording and evaluation of the productive qualities of animals. One of the stages of this process was implementation in 2015-2017. in the Stavropol State Agrarian University of research projects, especially significant for the agro-industrial complex of the Russian Federation in the direction of ensuring import substitution in animal husbandry (genetic material), which envisage the development of a regional model for the formation and management of highly productive genetic resources for dairy cattle. The object of the research was cattle (cows) of the North Caucasian population of the Ayrshire breed (n = 550), from which, based on the analysis of the materials of the primary zooveterinary records, groups of cows with 3-fold milking were formed to study the daily dynamics of fat and protein content in raw milk samples I, II and III milking, n = 240) and 2-fold milking (I and II milking - 180 cows). In the process of performing monthly analyzes of the quality of individual milk samples obtained from pedigree cows taken for 2- or 3-fold milking, it was found that a certain pattern is observed in the diurnal dynamics of fat and protein content in milk, which probably has a general biological nature and largely depends on the technological factor - the multiplicity of milking cows, which coincides, basically, with the regularities described in the methodology of the International Committee for Registration of Animals (ICAR). The nature of the dynamics of the concentration of fat in milk at 2- and 3-fold milking has, though a different mathematical form, but they have a general tendency: the fat in milk for milking cows, as a rule, is 10.77–10.98 % lower, than II and III milking. The variability of the protein concentration in milk during the day is the same as the fat dynamics, though it is less expressed than of fat and accounts 0.88%.
