The results of tests of a new combined feed additive Bioprotektin-KD based on milk thistle extract with the addition of a complex of bacteria of the genus Lactobacillus and Bifidobacterium to restore intestinal microbiota of animals are presented. Preclinical studies on the effectiveness of the feed additive were conducted on mice with experimental antibiotic-associated dysbacteriosis. Studies on the intestinal microbiota of mice revealed varying degrees of effect of different doses of feed additive on the recovery of resident microflora. The results of pre-clinical studies have proven the harmlessness, non-toxicity and efficacy of the feed additive. Clinical trials of the additive were carried out on productive animals. Its effect on the productivity of black-motley breed cows in a livestock farm in the Belgorod region was studied. The use of the functional feed additive Bioprotectin-KD had a positive effect on the milk productivity of black-motley breed cows. Cows in the experimental groups that received the feed additive had increased their milk yield per lactation by 209.41-499.01 kg compared to the control animals, which was 4.01-8.78%. The quality indicators of milk have increased. The composition of the microflora of the experimental (feed supplement recipients) and control calves was studied. It was found that the quantitative composition of probiotic flora in the intestines of young calves of the control group remained practically unchanged throughout the experiment. The number of indigeneous microflora (lactobacilli and bifidobacteria) increased in the experimental animals. The content of lactic acid microorganisms in the experimental calves began to increase on day 6 of feed supplementation and reached physiological norm on day 30. The safety index of the product has been calculated. The use of the functional feed additive Bioprotektin-KD in conditions of a livestock complex has improved such production indicators as calf survival, average daily weight gain, and milk productivity of cows in the experimental groups of animals as compared to the control ones.

Изучены особенности пищевого поведения коров-первотелок при скармливании ферментативно-пробиотических препаратов. Для изучения влияния пробиотиков на основе целюлозолитических бактерий рубца жвачных проводился опыт в условиях хозяйства Вологодской области. Были сформированы 3 группы первотелок черно-пестрой породы по 12 голов методом пар-аналогов с учетом кровности, удоя матерей за наивысшую лактацию, живой массы, количества дойных дней после отела и суточного удоя. Животные контрольной группы получали основной рацион,  коровам I опытной группы дополнительно скармливали по 50 г на 1 голову в сутки кормовую добавку на основе целюлозолитических бактерий рубца коров, а II опытной — такое же количество добавки на основе целюлозолитических бактерий рубца оленей. Продолжительность скармливания добавок составляла 90 дней. В результате исследований было установлено, что использование ферментативно-пробиотических препаратов положительно повлияло на пищевую активность и уровень молочной продуктивности первотелок. Коровы I и II опытных групп, получавшие дополнительно к основному рациону ферментативно-пробиотические препараты в сравнении с контрольной группой имели более высокие показатели по затратам времени на потребление корма — 8 и 25 мин., соответственно. Время, затраченное на жвачку, у первотелок II опытной группы было больше на 12 мин., чем у животных контрольной группы, в результате индекс пищевой активности у них был выше на 0,026 по сравнению с контролем. Использование добавок способствовало увеличению молочной продуктивности коров I и II опытных групп, по сравнению с контрольной, на 207 и 151 кг. Полученные результаты подтверждают положительное влияние ферментативно-пробиотических препаратов в кормлении коров, так как они способствуют повышению их пищевой активности и молочной продуктивности. The features of first-born cows’ nutritional behavior when feeding enzyme-probiotic preparations have been studied. To study the effect of probiotics based on the ruminants’ cellulolytic rumen bacteria, an experiment on a farm in the Vologda Oblast has been conducted. There were formed 3 groups of black-and-white first-born cows of 12 heads by the method of pairs-analogues, taking into account pedigree, mothers’ milk yield for the highest lactation, live weight, the number of milking days after calving and daily milk yield. The animals of the control group received the main diet, the cows of the I experimental group were additionally fed 50 g per 1 head per day of a feed additive based on cellulolytic bacteria of cow rumen, and the II experimental group were fed the same amount of an additive based on cellulolytic bacteria of deer rumen. The duration of feeding the additives was 90 days. The research found that the use of enzyme-probiotic preparations had a positive effect on the first-born cows’ nutritional activity and milk productivity level. The cows of the I and II experimental groups who received enzyme-probiotic preparations in addition to the main diet had higher indicators for the time spent on feed consumption in comparison with the control group — 8 and 25 minutes, respectively. The time spent on rumination was 12 minutes longer in the first group of experimental animals than in the control group; as a result, their food activity index was higher by 0.026 compared to the control group. The use of additives contributed to an increase in the milk productivity of cows of the I and II experimental groups, compared with the control group, by 207 and 151 kg. The obtained results confirm the positive effect of enzyme-probiotic preparations when feeding cows, as they help to increase their nutritional activity and milk productivity.

Todays is not possible to overcam the problem of the resistance of microorganisms to antibiotics by the development of new antimicrobial agents. Because the new drugs development is quite long process, and the addiction of microorganisms to the antibiotics occurs very fast, in resulting microorganisms become resistant. Prospective direction in solving the problem of antibiotic resistance is the use of bacteriophages, which lytically acting on the pathogens, not causing any toxic effect on the macroorganism. In the article highlight the use of the feed additive Bafasal, which was made on the basis of a specific bacteriophage to serovars of Salmonella, in particular S. enteritidis, S. typhi, S. paratyphi, S. typhimurium, S. branderburg, S. hadar. Poultry of the experimental group were used Bafasal from 1 to 14 days of the experiment, from the calculation on 10 chickens - 50 cm3 of feed additive dissolved to 0,5 % concentration, and from 15 to 35 days - 100 cm3 of Bafasal dissolved to 0,25 % concentration. As a result in the conducted researches was found out that Bafasal causes an increase of weight gain of broilers, feed conversion. In particular, on the 35th day of the experiment, the average daily weight gain of the chickens of the experimental group was on 4,5 % higher than in broilers of the control group, and the conversion of feed in the experimental and control chicken was 1.74 and 1.93 units, respectively. Herewith, in broilers of the control group were not isolated pathogenic microorganisms, including salmonella. In determining the influence of the feed additive on some representatives of the intestinal flora of broilers was found that, the use of feed additive didnt cause changes in total amount lactic acid and bifidobacteria, in broiler of test and control groups, in the glandular, muscular stomach, duodenum, cecum and colon.

A study of the effectiveness of the use of feed additive Liatoxil in vivo in broiler chickens to study the ability of feed additives to improve digestion and affect the digestibility of nutrients. For research was formed on the principle of analogues -day age. Feeding of the control group was carried out with standard feed. Feeding of the experimental group was carried out with standard feed, in which the feed additive Liatoxil was added at the rate of 2 g / kg. The calculation of the digestibility of nutrients of the experimental and control feed was determined by their content in the feed and manure in terms of absolutely dry matter. It is established that the studied feed additive has a positive effect on the digestibility of feed nutrients. As a result of the use of feed additive Liatoxil, the digestibility of organic matter increased by 2.8 % compared to the control. The coefficient of protein digestibility in animals of the experimental group exceeded this indicator of the control group by 4.2 % and was 93.3 % against 89.1 % in the control. The digestibility of crude fat in poultry of the experimental group was 77.8 % and also exceeded by 2.0 % the value of the control group, which was 75.8 %. The studied feed additive did not significantly affect the digestibility of crude fiber, which was 23.3 % in the control and 23.5 % in the experiment. At the same time, the obtained data show that in the animals of the experimental group the digestibility of nitrogen-free extractives was 87.5 %, which is 2.8 % higher than this indicator of the control group.

Abstract The aim of the research was to establish the effectiveness of the use of the feed additive “Lamarin Saldonum.” The feed additive contains Japanese kelp, milk thistle, to increase the milk productivity during the milking period. The studies were conducted on 40 cows of the black-and-white Holstein breed at the age of 2–4 lactation and the amount of milk for the last lactation not less than 7,500 kg. The cows were divided into 4 groups (GE1, GE2, GE3, GC) of 10 heads in each. Cows GE1, GE2, GE3 received 30 days before calving daily feed additive in doses of 0.1, 0.2, 0.3 g/kg, respectively, for 60 days. In the GC animals didn’t receive the feed additive (control group). Control milking was performed every 10 days. Using of feed additive in the ration increased milk productivity. In the 1st month of lactation, the average daily amount of milk in GC was 24.00±0.93 kg, which is 7.4%, 19.6% (P < 0.01), 7.4% less than in GE1, GE2 and GE3, respectively. In the 2nd month, the highest average daily amount of milk in GE2 and GE3, which is 13.4% (P < 0.01) and 4.6% more than the GC, respectively. In the 3rd month, the average daily amount of milk in GE1, GE2, and GE3 was 30.22±2.44 kg, 39.57±2.68 kg, 35.11±2.59 kg, respectively, which is 6.8%, 39.9% (P < 0.01), 24.1% more than in GC. The mass fraction of fat in milk in animals GE1, GE2, GE3 was 0.2–0.92%(P < 0.01) higher than in GC. In the second month of lactation, the mass fraction of protein in GE2 was higher by 0.24% (P < 0.01), in GE3–by 0.14 (P < 0.05) relative to GC. At the 3rd month of lactation, the protein content in milk was 0.29% higher in GE2 (P < 0.001) and GE3-by 0.21% (P < 0.001) than in GC.

Abstract. Title of the paper: Impaet of feed restriction on the growth performance of goat kids The influence of differential feeding levels on growth performance in 72 goat kids "Bunte Deutsche Edelziege" during the pre-weaning period was examined. The 72 animals were assigned to a control group and two experimental groups that received respectively 20% and 40% less milk/less concentrate compared to the control (fed at 2.4 times energy demand for maintenance). The experimental gained animals significantly less relative to the control group. However, during the subsequent realimentation period when all animals were fed at a energy level of 2.4 times maintenance same treatment, the daily weight gain among the kids was in inverse proportion to the level ofmilk deprivation in the pre-weaning phase. The rapid growth among the experimental animals was such that the initial differences in body weight between the experimental and control groups were fully compensated. Growth performance of kids with respect to different levels of concentrated feed was less clear cut and d.ffered significantly only behveen the group that received the lowest feed level relative to all the other groups.
