Studies were conducted on two groups of calves during the growing period from 1 to 6 months in conditions of unfavorable respiratory and gastrointestinal diseases. Calves of the experimental group with a diet were given dihydroquercetin and arabinogalactan at a dose of 1 and 75 mg/ kg of live weight / day, respectively. DHQ and AG, in accordance with their biological properties, provided a high level of antioxidant protection, the formation of microbiocenosis and intestinal immunity, correction and control of mineral homeostasis in the body of calves. As a result, there was a normalization and increase in the intensity of protein, nitrogen, lipid, carbohydrate, energy and mineral metabolism, improved the functional state of the liver and increased pathogenetic resistance, which generally had a positive effect on the formation of productive health, viability and resistance of the body to the action of biotic and abiotic environmental factors, safety and average daily growth of calves.

Method for using probiotic feed additive Prolaksim-V with a therapeutic and preventive effect to improve the indicators of live weight gain, feed conversion and the safety of poultry stock was proposed by the authors. Composition of Prolaksim-V feed additive is dominated by species of lactic and propionic bacteria: Streptococcus salivarius LT-1, Lactobacillus acidophilus LT-12, Streptococcus thermophilus LT-9, LT-10 and Propionibacterium freudenreichi LT-8. These bacteria perform an important physiological role in the organism due to their protective and synthetic functions, as well as participation in the final link of the digestive process. Probiotic flora plays a leading role in maintaining and normalizing intestinal microbiocenosis, maintaining non-specific resistance of the body, improving protein and mineral metabolism, etc. deficiency of lactic and propionic bacteria is one of the pathogenetic factors of long-term intestinal dysfunctions. It leads to a violation of mineral metabolism, to the formation of chronic digestive disorders. There is evidence that used bacteria are some suppliers of a number of essential amino acids, primarily tryptophan, as well as vitamins. Protective role of lactic and propionic bacteria in vivo is largely due to the formation of organic acids that prevent the development of putrid and pathogenic forms of microorganisms. The analytical action of these microorganisms is due to the presence of propionic and lactic acids, resulting in a decrease in the pH of the intestinal contents. It was found that the use of probiotic preparation in feeding broiler chickens contributes to an increase in the daily growth of poultry in the experimental groups, compared with the control. There was also an increase in the mass of gutted carcasses, improvement in feed conversion, and an increase in the safety indicators of poultry that receive probiotic together with the general diet.

ABSTRACTThirty-five Charolais × Blue-Grey and Charolais × (Hereford × Friesian) weaned suckled calves which had been reared as either singles or twins and 19 single-reared Luing and Charolais × Luing weaned suckled calves were given silagead libitumsupplemented with either 0·75 or 2·5 kg rolled barley per day during the post-weaning winter. During summer the cattle continuously grazed perennial ryegrass swards. The high level of barley supplementation increased winter live-weight gain by 0·25 kg/day (P< 0·001). During summer the cattle from the low level of feeding gained weight at 0·09 kg/day (P< 0·05) faster than those from the high level of feeding. However, by the end of the summer grazing period the cattle on the low level of feeding were proportionately only 0·97 the weight of the animals on the high level of feeding.During winter the performance of all genotypes was similar, but at pasture the Luing cattle gained less weight (P< 0·01) than the single-reared Charolais-cross genotypes.Twin-reared cattle took 55 days longer to reach slaughter condition, but produced carcasses of equal weight and fatness to those from single-reared cattle.The twin-reared cattle on the high level of feeding and the single-reared cattle on the low level of feeding attained a similar weight, body condition and ultrasonic backfat at turn-out. Thereafter, their herbage intakes and live-weight gains were identical suggesting that previous level of feeding per se is unimportant in determining an animal's subsequent intake and performance. Rather it is the body composition at a given age, irrespective of the pathway followed to attain that composition, that determines performance thereafter. It is also suggested that the inability of cattle to compensate for a reduction in level of nutrition during the first 3 to 4 months of life is due to the lack of potential for fat deposition, and there is thus limited opportunity for nutritional manipulation of body composition at that age.

The purpose of the research is to increase the effectiveness of the supplement Reasil on the growth of milk-fed calves. For the scientific and economic experience, three groups of calves were formed (control, 1 and 2 experi-enced). Groups of animals of 10 heads were formed according to the principle of analogues. The indicators of live weight, growth and blood of calves were studied after Reasil use in a diet: Reasil HumicVet as a liquid form, and Reasil Humic Health – reduced to powder. In the experiment, animals of a black-and-white breed were used. The Reasil feeding in the diet contributed to an increase in the live weight of milk-fed calves in the 1-st and the 2-nd experimental groups at two months of age by 5.65 and 5.48 kg (or by 7.4 and 7.2%), respectively, compared to the indicator of the control group analogues. The average daily growth of calves of the experimental groups exceeded this indicator of control animals by 96 and 82 g, respectively. The blood of calves of the 1st and 2nd experimental groups, showed that hematoglobin was higher by 15.7 and 11.4%, red blood cells – by 16.5 and 15.1%, and the alkaline reserve – by 5.2%, compared with blood of calves from the control group, which indicates the activation of metabolic processes in the body. The total protein amount in the blood serum of animals from the experimental groups increased by 8.4 and 5.9% respectively, compared to the tests of calves from the control group. The albu-min content of animals of the 1st experimental group tested was higher by 5.3%; from the 2nd experimental group there was no significant difference compared to the control. The number of gamma-globulins in the blood of ani-mals of the experimental groups increased, which indicates an increase in defense reaction of animals. The con-tent of calcium in the blood serum of calves from the experimental groups was higher by 8.3 and 5.9%, phosphorus – by 4.8 and 2.4%, which indicates a more effective use of these mineral elements.

Abstract. The purpose of the study is to determine the effect of zeolite honguruu on the growth and development, digestibility and metabolism of geese in the conditions of Yakutia. During the experiment, research methods generally accepted in poultry farming were used. Live weight – by weighing birds, digestibility and metabolism according to the method of VIZH, VNITIP. The scientific novelty of the research was to find the possibility of involving natural zeolite in the feed ration of young goose young in the conditions of Yakutia. For carrying out the experiments, we formed 3 groups of geese of 20 animals in each analogue method. Therefore, we determined the effect of zeolite on growth, development, physiological state, and digestibility of nutrients. The purpose of the research is to identify the degree of safety when using zeolite in poultry farming and to obtain an environmentally friendly product for human nutrition. The use of zeolite contributed to an increase in gross increase in live weight by 14.13 % and 19.22 %. So, the supplement contributed to an increase in average daily growth during all periods of cultivation: in 60–70 days – 7.85 % and 15.24 %; in 70–80 days – by 21.73 % and 28.30 %, in 80–90 days – by 13.61 % and 15.76 %. During the experiment, the control group of geese accounted less than the experimental groups of birds – 14.14 % and 19.22 %. A physiological experiment was conducted to determine the effect of zeolite honurin on metabolism. It was found that the additive contributes to better digestion of nutrients in terms of dry matter by 0.9 % and 1.58 %, organic matter by 0.83 % and 1.38 %, protein by 0.64 % and 0.92 %, fat by 0.84 % and 1.58 %, fiber by 0.33 % and 2.21 %, and nitrogen-free extractives by 0.96 % and 1.42 %. During the experiment, it was found that the nitrogen balance in all geese was positive but had differences in the degree of deposition in the body. So the experimental geese of the experimental groups exceeded their peers from the control group by 3.47 % and 5.56 %, respectively. Thus, the use of zeolite zeolite is positive for the growth and development, digestibility and metabolism of geese.

The drug Argovit developed in the LLC Vector-Vita Research and Production Center has antimicrobial and astringent properties, easily fits into the technology of housing farm animals and poultry in cases of uncomplicated colibacteriosis and is effective in isolated use, it is cheaper than other drugs, which makes it attractive in the modern market of biological products. The purpose of the research was to study the effectiveness of the drug Argovit for the treatment and prevention of gastrointestinal diseases of piglets in comparison with the basic drug Baitril used in the farm. Piglets of the experimental group (n=20) with the syndrome of gastrointestinal diseases have been treated with 1,0 % aqueous solution of the drug Argovit at a dose of 2 ml/kg of live weight 2 times a day until clinical recovery. The drug contributed to a lighter course and reduced the duration of the disease by half, while the livability of piglets reached 90,0 %. There was also a weakening of inflammatory processes in the body of piglets of both groups, which was characterized by the decrease in the level of leukocytes in piglets of the experimental group during treatment from 12,9±0,75 to 10,1±0,89×10⁹/l, and in the control group from 11,3±1,20 to 9,0±0,04×10⁹/l. The platelet content in animals at the beginning of the experiment was slightly higher than the lower limit of the norm in the experimental group by 1,8 %, in the control group by 4,7 %. At the same time, the restoration of homeostasis and the decrease in the level of protein in the blood serum have been observed. It has been found that the use of the drug Argovit to piglets during the suckling period and after weaning improves the morphological and biochemical parameters of blood due to the protective forces of protein by 4,7 %, reduces the phenomena of diarrhea, and as a result increases their livability.

Bacteria of the genus Pseudomonas aeruginosa are widespread microorganisms in pig breeding enterprises of the region, and due to virulent factors and pathogenic properties, in the etiological aspect, it poses a significant threat to the body of various sex and age groups of pigs. In the form of a monoculture, Pseudomonas aeruginosa was isolated in 14.7% of cases, in association with other microorganisms - in 85.2%, and the highest proportion of Pseudomonas aeruginosa was manifested in association with Escherichia coli (47.8%), microorganisms that cause the clinic of gastrointestinal diseases in piglets during suckling and weaning periods. A feature of the epizootic manifestation of pseudomonosis in pigs in the conditions of industrial pig breeding is enzootic outbreaks. In 79.9% of cases, growth is accompanied by the formation of a water-soluble pigment of the phenotazine series pyocyanin on selective nutrient media in isolate colonies, in 80-83 % of cases, on MPA with 5 % defibrinated blood, Pseudomonas aeruginosa colonies cause hemolysis zones. Biochemical activity of P. aeruginosa cultures showed low-expressed biochemical properties, they assimilated glucose and arabinose, galactose to the formation of acid, decomposed urea, had proteolytic properties, liquefied gelatin and peptonized milk for 72 hours, showed phosphatous activity, did not form indole and H2S, cultures producing exotoxin A, with intraperitoneal infection of laboratory animals show maximum toxigenic properties. Pseudomonas aeruginosa isolates exhibit plasma-coagulating and agesive activity. The obtained results of studying the main biological properties of P. aeruginosa isolates can be used for diagnostic studies and anti-epizootic measures in the region.

This article shows data analysis of the correlation between the live weight of Obroshynska gray and Obroshynska white natural groups geese and the weight of the incubation egg, beside this the age repeatability of the live weight of the poultry has been investigated and the correlation variability of the aforementioned indicators and body measurements of the females and males of geese breeds have been analyzed. It was established that the most significant and highly reliable correlation bundles were between live weight and the weight of the incubation egg were detected in one day aged geese. In another researched age periods, these connections were sharply weakened and at 60-day aged geese reached the minimum values and were inconceivable. With the increase of the interval between the comparable age periods and the coefficients of repeatability of live weight were declined. In Obroshinsky gray natural group geese females – the coefficients of repeatability of live weight were depending on age and they ranged from 0.01 to 0.55, in males – from 0.01 to 0.57, and in the bird of the Obroshinsky white natural group geese were from 0,03 to 0.53, and from 0.02 to 0.65 respectively. In 30 to 60 days of aged geese of both sexes of both natural groups the coefficients of repetition of live weight were the highest and reached more than 50% at their high level. This indicates that live weight of geese selection can be carried out already at 30-day aged geese. The highest coefficients of the correlation in the birds of both geese natural groups were observed in all studied age periods between the live weight and the width of the pelvis, the length of the trunk, the length of the keel and the chest covering of the shoulder blades: in females they were within the range of 0.58–0.96, and in males – in the range 0.50–0.96 at P < 0.001 in all cases. However, it should be noted that the correlation of live weight, the length of the body and the length of the keel in both sexes geese from Obroshinsky gray natural group were more significant than in geese from Obroshinsky white natural group, but the correlation bonds between the living weight with the width of the pelvis and the chest covering of the shoulder blades on the contrary, were weaker. The weakest correlation were detected between the live weight and the length of the mold, leg and thigh in the poultry of both sexes of both groups in the 30–60 days aged geese.

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.

1. Twelve castrated male pigs were kept at each of three temperatures and given food at one of three levels of intake. The temperatures and daily food intakes (expressed as g/kg0.73) were 23° (80, 100, 120), 13° (100, 120, 140), 3–5° (120, 140, 160). Growth and nitrogen metabolism were measured during growth from 20 kglive weight until slaughter at gokg live weight, when the body contents of N and fat were estimated.2. Growth rate increased with each unit of daily food intake (I g/kg0.73 live weight) by 7.73 ± 0.74 g/d. This value did not vary significantly with temperature. Daily growth rate was depressed by 17.8 ± 2.3 g for each I° fall of temperature.3. Daily N retention estimated by the balance method exceeded by 2.59 g/d that estimated by the comparative slaughter technique. Both results led to the same conclusion, which echoed that found with growth rate, that there was no significant effect of temperature on the response of N retention to increasing food intake. Taking the mean of the two estimates, N retention at a constant food intake fell by 0.38±0.055 g/d for each I° fall of temperature.4. The N content of the ingesta-free carcass at slaughter fell with each increase in daily food intake by 0.007±0.002%, and the fat content rose correspondingly by 0.116±0.027%. These regressions did not vary significantly with temperature. When considered at a constant food intake, body composition did not alter significantly with temperature.

SUMMARYEwes in body condition scores of 2·4 (thin) or 3·2 (fat) on a 5-point scale and suckling twin lambs were grazed at two stocking rates for the first 16 weeks of lactation. Paddocks were grazed for periods of 2 weeks at densities of 80 and 160 ewes/ha in weeks 1–8 and then 70 and 140 ewes/ha in weeks 9/16 of lactation.Intakes of herbage by ewes were not significantly affected by body condition. Estimation of milk yield by weekly measurement of secretion rates over 4 h failed to demonstrate significant differences due to body condition except in weeks 9, 11 and 12, although there was a tendency throughout for fat ewes to produce more milk. However, the daily growth rates of the lambs during the first 8 weeks and the overall live-weight gains were significantly higher for lambs suckled by fat ewes than for those suckled by thin ewes. Intake of herbage by lambs was not affected by the body condition of the ewes.Herbage intakes, milk yields and lamb growth rates were all significantly higher at the low stocking density than at the high stocking density.
