Intensive dairy farming in modern conditions is impossible without a solid forage base and the use of high-quality forage resources. A high level of cow productivity presupposes adequate nutrition for the animal at all physiological periods of its life. Due to the fact that cows consume relatively little feed during the first period of lactation, the primary task of livestock breeders is to provide the body of highly productive animals with the necessary amount of energy, protein and other nutrients. The article presents the data of a scientific experiment on the use of non-degradable protein in the rumen PassPro Balance in diets for fresh cows. The feed additive under study contributes to an increase in the level of dry matter consumption by animals. The average daily milk yield of the experimental group, which received the studied supplement, significantly increased by 12.0% (P <0.05) in comparison with the control group. There was also established a tendency to an increase in the fat content in the milk of cows from the experimental group. According to the biochemical analysis of the blood serum of cows, the level of albumin in all animals was within the physiological norm. The content of globulins was below the norm in animals of all groups without significantly significant differences. The activity of the AST and ALT enzymes between the groups did not differ significantly. However, it should be noted that in both groups these indicators were within the normal range. The level of alkaline phosphatase tended to increase in the experimental group by 20.8% in comparison with the control group. Feeding PassPro Supplements Balance in the diets for the experimental group made it possible to receive 2565,00 rubles of additional profit, while the level of profitability of milk production increased by 2.02% relative to control.

The results of research on the use of the feed additive “Ecostimul-2” and natural zeolite from the Khonguruu deposit in the Suntarsky district of the Republic of Sakha (Yakutia) in the rations of lactating cows have been presented in the article. The purpose of the work was to study the influence of feed additives “Ecostimul-2” and zeolite on the digestibility of nutrients and nitrogen metabolism in lactating cows of Kholmogorskaya breed under the conditions of Central Yakutia. Chemical analysis of feed, accounting of dairy productivity of cows has been carried out according to generally accepted methods. The cows of the control group have received the main ration. The cows of the experimental groups have been additionally received to the main ration: the 1st experimental feed additive “Ecostimul-2” in the amount of 200 mg/head/day, and the 2nd experimental group – “Ecostimul-2” in the amount of 200 mg/head/day and zeolite 200 g/head/day. The inclusion in the ration of lactating cows of Kholmogorskaya breed under the conditions of Central Yakutia of feed additives “Ecostimul-2” and zeolite of the Suntarsky deposit together has increased the digestibility of feed in the ration and improved the digestibility of nutrients and nitrogen metabolism. It has been found during the experiment that in cows have been receiving the feed additive “Ecostimul-2” and zeolite with the main ration (the 2nd experimental group) the average daily milk yield was 9,06 kg with a fat content of 3,8 % or was by 10,4 % higher than in the control group. In cows that have been received feed additive “Ecostimul-2” (the 1st experimental group) the average daily milk yield was 8,76 kg with the fat content of 3,77 % or was by 6,8 % more than in the control group.

In order to effectively provide the body of cows with energy during the increasing the milk yield without the risk of acidosis, progressive animal breeders of the Altai Territory include wet flattened corn grain in the composition of concentrated feed. The question of the expediency and economic effectiveness of using wet flattened corn grain for cows of various physiological groups – first-calf heifers and mature animals continues to be debatable. Therefore, a comparative assessment of two options for feeding wet flattened corn grain to cows under the conditions of the Altai Territory is considered promising in modern animal husbandry and is of great practical interest. The purpose of the work was to identify the optimal and economically feasible option for using wet flattened corn grain in the rations of lactating cows. When using wet flattened corn grains in an amount of 7,1 % of the nutritional value of the ration the first-calf heifers during the period of increasing the milk yield, productivity has increased by 20,9 %. The average daily milk yield was 17,3 kg, which significantly exceeded the indicator of the control group (P > 0,95). The inclusion of wet flattened corn grains in the ration of mature cows in the amount of 1 kg for 30–35 days before calving, then 4,5 kg from 15 to 75 days after calving allows us to get the average daily milk yield of 30 kg or 20,3 % higher than that of the control group of herdmates (P > 0,95). The effectiveness of the use of wet flattened corn grain had significant indicators: the total profit from the sale of dairy products of the first-calf heifers of the experimental group amounted to 16 251,3 rubles/head, and from the sale of milk of mature cows of the experimental group it was 30 346,43 rubles/head.

Изучено влияние белково-витаминного минерального концентрата (БВМК) на молочную продуктивность коров и рассчитана экономическая эффективность его применения. Для проведения опыта с учетом количества дней лактации были сформированы 3 контрольные и 3 опытные группы по 10 голов. В I контрольную и I опытную группы вошли животные на стадии раздоя (30—60 дней лактации), во II контрольную и II опытную группы — коровы в середине лактации (150—180 дней), в III контрольную и III опытную — животные в конце лактации (240—270 дней). Для коров опытных групп были составлены рационы с БВМК, которым заменяли пропорциональное количество концентрированных кормов и часть витаминно-минерального премикса. Коровы I опытной группы получали с рационом БВМК «Статус VI» в количестве 1200 г, II опытной — БВМК «Статус I» по 350 г, III опытной — БВМК «Статус I» по 250 г на 1 голову в сутки. Максимальный уровень молочной продуктивности по результатам опыта показали животные II опытной группы. Среднесуточный удой за 60 дней опыта у них составил 46,1±1,11 кг, что больше на 4,7 кг молока, или на 11,4% (P≤0,05), чем во II контрольной группе. В период раздоя среднесуточный удой за 60 дней опыта в I контрольной и I опытной группах был на уровне 36,4±1,37 кг и 42,4±1,22 кг молока соответственно. Достоверное различие (P≤0,01) между ними составило 6,0 кг молока, или 16,5%. Наименьший среднесуточный удой за период опыта показали животные III контрольной (26,4±1,20 кг) и III опытной (28,5±1,53 кг) групп. Различие между ними было менее существенным, чем у коров в период раздоя и в середине лактации, и составило 2,1 кг, или 8,0%. Применение БВМК в кормлении лактирующих коров дало выраженный экономический эффект. Дополнительно полученная прибыль в расчете на 1 голову в сутки составила: в I — 127,4 руб., во II опытной группе — 117,0 руб., в III — 33,4 руб. The influence of PVMC on the milk productivity of cows has been studied and the economic efficiency of its application has been calculated. To experiment, taking into account the number of days of lactation, 3 control and 3 experimental groups of 10 animals each were formed. The 1st control and 1st experimental groups included animals at the milking stage (30—60 days of lactation), the 2nd control and 2nd experimental groups — cows in the middle of lactation (150—180 days of lactation), 3 control and 3rd experimental — animals at the end of lactation (240—270 days of lactation). For the cows of the experimental groups, rations were made with PVMC, which was replaced by a proportional amount of concentrated feed and a part of the vitamin and mineral premix. Cows of the 1st experimental group received a diet of PVMC «STATUS VI» in the amount of 1200 g / head/day, the 2nd experimental group — PVMC «STATUS I» at 350 g / head/day, the 3rd experimental group — PVMC «STATUS I» 250 g / head/day. The maximum level of milk productivity according to the results of the experiment was shown by the animals of the 2nd experimental group. The average daily milk yield for 60 days of the experiment was 46.1±1.11 kg, which is more by 4.7 kg of milk or 11.4% (P≤0,05) than in the 2nd control group. During the period of milking, the average daily milk yield for 60 days of the experiment in the 1st control and 1st experimental groups was at the level of 36.4±1.37 kg and 42.4±1.22 kg of milk, respectively. A significant difference (P≤0,01) between them was 6,0 kg of milk or 16.5%. The smallest average daily milk yield throughout the experiment was shown by the animals of the 3rd control (26,4±1,20 kg) and 3rd experimental groups (28.5±1.53 kg). The difference between them was less significant than in animals during the milk period and in the middle of lactation and amounted to 2.1 kg or 8,0%. The use of PVMC in feeding lactating cows gave a pronounced economic effect. Also, the profit received per head per day was: in the 1st experimental group (milking period) — 127.4 rubles; in the 2nd experimental group (mid—lactation) — 117.0 rubles; in the 3rd experimental group (end of lactation) — 33.4 rubles.

Aim of the research was to study the effect of premix with buffering properties in diets for newborn cows on their milk production, blood biochemical composition, microbiological parameters of scar fluid and its acidity. The experiment was carried out on 2 groups of calving black-motley cows, selected on the basis of the pair-analogue principle with 6 animals each. The first, control group of cows received a ration adopted on the farm. The second group of animals received the same diet, only instead of 0.5 kg of compound feed they used a multicomponent mineral premix enriched with biologically active additives, which has buffering properties, which is very important in the newborn period of cows. Feeding premix with buffering properties in the composition of the main diet to newborn cows contributed to an increase in the consumption of dry matter by animals. Since the cows of the second experimental group consumed more nutrients, a significant increase in the average daily milk yield was found. The studied premix helped establish a tendency to improve metabolic processes in the body of ruminants. In a scientific experiment, a positive effect of the buffer premix on the microbiological parameters of scar fluid, as well as its acidity and acid-binding ability, was established. The consumption of more nutrients was due to a significant increase in average daily milk yields by 9.1%. The results of biochemical studies of blood serum allow us to say that all indicators characterizing the metabolism were within the physiological norm in cows of both groups. Also, a qualitative change for the better in the microbiological parameters of scar fluid was noted. Feeding the studied premix to experienced animals contributed to the additional profit of 4069.8 rubles per head.

Изучено влияние на продуктивность коров нового активатора рубцовой микрофлоры — «МегаБуст Румен» (МБР) на основе инактивированного ферментационного экстракта Trichoderma longibrachiantum и специализированного штамма дрожжей Saccharomyces cerevisiae в двух опытах. В первом эксперименте в опытной группе коровы в транзитный период получали по 100 г/день МБР за 7 дней до отела и с 1 по 150-й день лактации, в остальном содержание и кормление животных опытной (n=10) и контрольной (n=10) групп было идентичным. В среднем в сутки коровы в опытной группе давали молока 41,26±0,91 кг при среднем содержании молочного жира 3,8±0,33% и белка 3,34±0,06%, что на 6,81±0,62 кг молока больше (Р<0,05), чем в контрольной группе (34,82±0,78 кг при среднем содержании молочного жира 3,55±0,13 и белка 3,08±0,09%). Использование МБР в опытной группе способствовало существенному увеличению среднесуточного удоя (+1500 кг) в опытной группе по сравнению с контрольной на 1 голову, пересчитанного на содержание жира 3,5%, за первые 150 дней лактации. Экономический эффект применения МБР — это дополнительный чистый доход на 1 голову за период эксперимента — 40037 руб. Во втором опыте, который проводился на всей группе лактирующих коров, при скармливании на 1 голову в сутки 100 г МБР отмечали повышение добровольного потребления сухого вещества (+2 кг СВ), увеличение среднесуточного удоя (+4,4 кг) на 1 голову в день. Возврат инвестиций в активатор рубцовой микрофлоры на 1 руб. составил 12,7 руб. The effect of new rumen microflora activator — MegaBust Rumen (MBR) on the basis of inactivated fermentation extract Trichoderma longibrachiantum and a specialized strain of yeast Saccharomyces cerevisiae on the cows productivity was studied in two experiments.In the first experiment, in the experimental group, the cows received MBR in the dose 100 g/day in the transit period 7 days before calving and from the 1st to the 150th day of lactation, otherwise the keeping and feeding of the animals of the experimental and control groups were identical. In average, per day, cows in the experimental group gave milk 41.26±0.91 kg with an average content of milk fat of 3.8±0.33% and protein of 3.34±0.06%, which is 6.81±0,62 kg of milk is more (P<0.05) than in the control group (34.82±0.78 kg with an average content of milk fat of 3.55±0.13 and protein of 3.08±0.09%). The use of MBR in the experimental group contributed to a significant increase in the average daily milk yield (+1500 kg) in the experimental group compared to the control for 1 head, calculated on the fat content of 3.5% for the period of first 150 days of lactation. The economic effect of the use of MBR is an additional net income per head for the period of the experiment was — 40037 rubles. In the second experiment, which was conducted on the entire group of lactating cows, when feeding 100 g of MBR per head per day, an increase in voluntary consumption of dry matter (+2 kg DM), an increase in average daily milk yield (+4.4 kg) per 1 head per day were noted . Return on investment in the activator of ruminal microflora by 1 ruble amounted to 12.7 rubles.

Reasil® Humic Vet is a liquid water-soluble feed additive with complex action. The aim of our research was to study the effect of the liquid feed additive "Reasil® Humic Vet" on the productive qualities and the digestibility of nutrients in compound feed by laying hens. The drug was drunk for 14 days with a break between courses of 7 days at a dose of 0.25, 0.50 and 0.75 ml / 1 liter of water. The highest egg production was obtained in chickens, the second experimental group -84.69%. The weight of 1 egg in this group also turned out to be higher than -63, 10 g. All this led to an increase in the egg weight to 31.09 kg, while reducing feed costs to 2.17 kg. The digestibility of organic matter in the experimental groups was 75.45, 75.44 and 75.37%, which is significantly higher than in the control group by 0.66, 0, 67 and 0.59%, respectively (P <0.05). The drug used with a high degree of reliability stimulated an increase in the digestibility coefficients of protein, fat, fiber (P <0.01) in chickens from 1 and 2 experimental groups. Increasing the amount of the supplement to the maximum dose did not significantly affect protein digestibility. Fat, fiber and dry matter in general in the 3rd experimental group had digestibility coefficients, the difference of which with those of the control group was confirmed by biometric processing (P <0.05 and 0.01).

Currently it has become popular to use different feed additives that allow us to increase the indicators of live weight gain by accelerating the metabolic processes in the body of animals, which allows us to take everything from the feed and to the maximum. With the advent of this trend in the market the range of feed additives in different directions has increased. For the research we have selected Vermiculite Expanded as a feed additive. The purpose of the research was to search the dynamics of changes in blood parameters in experimental steers in comparison with the control group against the background of the use of the feed additive Vermiculite Expanded. An assessment of blood parameters of Kazakh White-headed steers against the background of the use of mineral feed additive has been presented in the article. Three groups of steers have been formed for the research: the 1st group has been as a control and received the main economic ration; the 2nd and 3rd experimental groups received the feed additive to the main feeding ration in doses of 10 and 15 g/head for the groups, respectively. On the laboratory base blood tests we were able to search the correlation between morphological and biochemical parameters of blood and the growth rate of experimental steers. The steers of the 2nd and 3rd groups during the experiment had an advantage in blood serum indicators in terms of both total lipids and glucose, in the end, the difference in percentage ratio with the control group was 14,08 % in the 2nd group and 12,60 % in the 3rd experimental group. It is worth noting that the concentration of phosphorus and calcium in the blood was at the high level, which in our opinion reflects the influence of the feed additive Vermiculite Expanded.
