This paper shows the results of production and chemical compo­sition of cow’s milk on a farm MILKO-HF, Prilep, R. Macedonia with capacity of 100 cows of Holstein-Frisian breed divided into two groups (control and experimental). In control group I which was fed in a standard way of nutrition (ration used on the farm), average daily production of milk per cow ws 22.49 kg with the following chemical composition of milk: average daily content of milk fat is 3.75%, protein 3.57%, lactose 4.65%, nonfat dry matter 9.56% and total dry matter 13.31%. In experimental group II which were fed with the ration according to normatives, average daily production of milk per cow is 24.04 kg with the following chemical composition of milk: average daily content of milk fat is 3.99%, protein 3.57%, lactose 4.65%, non-fat dry matter 9.58% and total dry matter 13.57%. The obtained results show the increase in milk production for 1.55 kg-6.89% and better chemical composition of milk in the experimental group of cows. Thus, dry matter was increased from 13.31% to 13.57%-1.95%, milk fat content from 3.75% to 3.99%-6.4%, nonfat dry matter from 9.56% to 9.58%-0.21%, while the content of protein and lactose stayed on equal level. It was determined that the normed nutrition has influenced on production increase and better chemical composition of milk without unnecessary spent high level of nutrient i.e. nutrition of cows according to recommended normative.

Research has been carried out to study the influence of "ProBioKorm Uz", a biologically active feed additive, on the development and physiological characteristics of rabbits of ‘New Zealand’ breed. During the experiment, 2 experimental and a control groups were formed. Adding "ProBioKorm Uz" to the main feed at the rate of 1% and 2% had an increase in experimental group rabbits’ live weight. Average live weight of them was higher by 5,7 %-3.8% than in the control group. Feed units composed 1.59%, dry matter 0.56 kg (3.61%) and crude protein 0.11 kg (3.59%) compared with the control group. Rabbits of experimental groups had higher indicators of erythrocytes concentration by 0.34-1.00 1012/l (10.34-19.53%), leukocytes - by 0.370-0.46 109/l (5.66-8, 06%), as well as a high level of hemoglobin by 7.42-11.08 g/l (6.81-10.08%) and total protein - by 2.40-4.48 (3.64-6, 42%).

Milk production under grazing conditions is carried out in the intertropical region of hot climates due to its low production cost. The Tropical Milking criollo breed (LT) is characterized by its hardiness in this region, and its high milk quality and cheese yield. Grazing supplementation can increase milk production; however, it can also change its chemical composition. The effect of supplementation with commercial feed in LT cows was evaluated concerning the quantity and physicochemical traits of their milk by lactation. The treatments used were feeding based only on grazing para grass (Brachiaria mutica) and grazing plus 1 kg supplementation with 20 % protein commercial feed for every 5 kg of milk produced daily. The daily milk production per cow increased from 5.82 ± 0.18 to 7.10 ± 0.18 kg due to supplementation. Dry matter intake was similar in both treatments. The concentration of fat, protein, lactose, non-fat, and total solids did not suffer modifications (p > 0.05), but the daily production of each component per cow increased in animals supplemented due to the multiplicative effect of the amount of milk. The number of calvings affected milk production, fat, and ureic nitrogen in milk, and somatic cell count (p ≤ 0.05). It can be concluded that the supplementation used in this study was enough to increase milk production by 22 %, without modifying its chemical composition.

It was found that the inclusion of water enriched with molecular hydrogen into the diet of a long-tailed chinchilla changed the fur quality indicators. In animals of the experimental group, the guard and downy hairs were thinner than in the control group. The length of downy hair in the experimental group was higher, the number of hairs in the follicle in the chinchillas of the experimental group was greater than in the control group, besides, the hair was stronger and softer. The animals of the experimental group showed less tendency to gnaw out fur. When considering the data on the chemical composition, it was found that in the dry matter of the hair of the animals of the experimental group, there were less organic substances, and there were more minerals in comparison with the animals of the control group.

Anaerobic fungi were orally dosed to lactating buffaloes to study their effect on the digestibility of a diet (composed of 50% wheat straw and 50% concentrate along with six kg maize green/animal/day), rumen fermentation patterns and milk production. Group I (control) was administered with fungus-free anaerobic broth, while group II and III were administered with Orpinomyces sp. C-14 or Piromyces sp. WNG-12 (250 ml; 3-5 days of growth/animal/ week), respectively. Milk production was higher in group II and III (8.42 and 8.48 kg/d) than in the control (8.03 kg/d) with virtually the same feed intake (i.e. 11.50 and 10.62 and 11.79 kg, respectively). There was an increase of 6% fat-corrected milk yield/animal/day in group II and III, respectively compared to the control. The milk fat was higher in the fungal culture administered groups than in the control group. The digestibility of dry matter, crude protein, neutral detergent fibre, acid detergent fibre, cellulose and digestible energy also increased significantly in group II and III. The pH and ammonia nitrogen were lower, whereas total volatile fatty acids, total nitrogen, trichloroacid precipitable nitrogen and number of zoospores/ml of rumen liquor were higher in group II and III when compared to the control. Hence, it can be stated that rumen fungi can be used as a direct-fed microbial in lactating buffaloes, to enhance the digestibility of wheat straw based diets leading to higher production.

В условиях Якутии опытным путем доказано положительное влияние использования кормовых добавок из местных ресурсов в рационах дойных коров на переваримость питательных веществ, использование энергии и повышение молочной продуктивности. Рацион коров состоял из сена разнотравного (10,0 кг) , силоса овсяного (18,0 кг) и комбикорма (2 кг). Животные I опытной группы с хозяйственным рационом получали рецепт №1 из ячменя «Тамми» (27%), овса «Покровский» (35%), пивной дробины (32%), минерального премикса «Мегамикс» (1%), пробиотического препарата «Хонгуринобакт» (2%), поваренной соли (1%). Коровы II опытной группы получали рецепт №2 из ячменя «Тамми» (31%), овса «Покровский» (25%), пивной дробины (38%), минерального премикса «Мегамикс» (1%), пробиотического препарата «Хонгуринобакт» (2%), поваренной соли (1%). Высокий уровень переваримости питательных веществ у коров II опытной группы, по сравнению с животными контрольной и I опытной групп, установлен в отношении сухого вещества на 1,0 и 1,5%, органического вещества — на 2,8 и 2,0%, сырого протеина — на 3,3 и 2,0%, сырого жира — на 2,3 и 1,5%, сырой клетчатки — на 3,0 и 2,0% и БЭВ — на 0,5 и 1,3%. Выявлено, что при одинаковой переваримости коровы контрольной группы потребляли меньше валовой энергии на 4,8 и 3,5 МДж, хуже переваривали энергию на 2,0 и 1,5 МДж. При сравнительно одинаковых потерях энергии выход обменной энергии у коров I опытной группы был выше на 1,5 и 1,1 МДж, чем у сверстниц. За 238 дней лактации получено молока больше, чем от коров контрольной, на 238 кг, или на 10,5% (Р<0,01), и I опытной групп — на 95,2 кг, или на 4,0% (Р<0,05). In the conditions of Yakutia, the positive effect of the use of feed supplements from local resources in the diets of dairy cows on the nutrients digestibility, energy use and an increase in milk productivity has been experimentally proven. The cows' diet consisted of herb hay (10.0 kg), oat silage (18.0 kg), and compound feed (2 kg). The animals of the 1st experimental group with the bulk moulding compound diet received recipe No. 1 from Tammi barley (27%), Pokrovsky oats (35%), brewer's pellet (32%), Megamix mineral premix (1%), probiotic preparation Khongurinobact (2%), sodium chloride (1%). Cows of the II experimental group received recipe No. 2 from Tammi barley (31%), Pokrovsky oats (25%), brewer's pellet (38%), Megamix mineral premix (1%), probiotic preparation Khongurinobakt ( 2%), sodium chloride (1%). A high level of digestibility of nutrients in cows of the II experimental group, in comparison with animals of the control and I experimental groups, was established in relation to dry matter by 1.0 and 1.5%, organic matter by 2.8 and 2.0%, crude protein — by 3.3 and 2.0%, crude fat — by 2.3 and 1.5%, crude fiber — by 3.0 and 2.0% and nitrogen-free extractive substances — by 0.5 and 1.3%. It was found that with the same digestibility, the cows of the control group consumed less gross energy by 4.8 and 3.5 megajoule, and digested energy worse by 2.0 and 1.5 megajoule. With comparatively equal energy losses, the yield of metabolic energy in cows of the I experimental group was higher by 1.5 and 1.1 megajoule than in their herdmates. During 238 days of lactation, milk was obtained more than from the control cows by 238 kg, or 10.5% (R<0.01) and the experimental group I — by 95.2 kg, or 4.0% (R<0.05).

Studies are devoted to the study of the qualitative indicators of the muscle tissue of bulls of brown Swiss breed, depending on the technology of cultivation. It was established that the highest content of dry matter and protein was characterized by the meat of animals of the first experimental group, contained according to the traditional technology using feeding. Their superiority in the dry matter content in the total meat sample of animals of the II and III groups was 0.9 (P<0,001) and 0,45%, respectively, and in the protein content –1.64 (P<0,001) and 0,75% (P<0,001). The ratio of protein / fat was higher in the bulls of the first control group and amounted to 1,09 against 0,95 and 1,03 in the second and third groups. An analysis of the biological usefulness of the protein showed that in the longest back muscle in the content of tryptophan, animals of group I surpass analogs of group II by 11,1 mg%, and in the content of  hydroxyproline are inferior to them by 1,9 mg%. The highest protein-quality index was in bulls of group I, which were grown using feeding, the superiority of which over analogues of group II was 5.85% (P<0,001). Animals of the third experimental group occupied an intermediate position in this indicator and exceeded their peers of group II by 3,77% (P<0,05).

The article presents experimental data on the effect of nickel citrate obtained using nanotechnology on the biochemical parameters of cows’ blood. The animals were divided into 3 groups. Group I was the control one. The animals of the II and III experimental groups received a feed additive of nickel citrate in the amount of 0.1 and 0.3 mg/kg of dry matter of the diet daily during the ninth month of lactation and the first two months after calving. It was found that the addition of both doses of nickel citrate to the transition cows diet contributed to positive changes in some biochemical parameters. A decrease in the content of lipid hydroperoxides, TBA-active products, as well as phenolic compounds was revealed. It should be noted that supplementation cows with nickel citrate in the first month after calving led to a significant increase in the content of lipid hydroperoxides by 15.1% in the third experimental group (P<0.01) against decrease in the level of TBARS by 14.8% compared with the control group (P<0.05). Feeding cows of nickel citrate in the amount of 0.1 mg/kg of dry matter stimulated the binding of free phenols and increased the concentration of their conjugated compounds, particularly phenolglucuronides, in the blood of animals of experimental group II by 20.2% (P<0.05). Instead, the use of nickel citrate in the amount of 0.3 mg/kg of dry matter contributed to a more pronounced activation of detoxification function with increasing concentrations of phenolsulfates and phenolglucuronides in the blood of animals of experimental group III compared with animals of control group by 23.1 and 21.2% (P<0.05).
