The article presents the results of research on the use of feed additives (E-selenium, Butophan OR, Nitamine OR) when keeping chickens in the period of 20–29 weeks of age. It was found that the intensity of egg laying in the experimental groups during the study period was 1,6–2,6% higher than in the control group. Minimum feed consumption (1,33 kg per 10 PCs. eggs) was set in the 2nd and 3rd experimental groups, which was lower than in the control group (by 0,02–0,1 kg). In all experimental groups (except the 1st), 100% safety of livestock was registered. In addition, a significant influence of the studied preparations on the commercial quality of eggs was established. In all experimental groups, the average egg mass was 0,5–2 g higher, and the total egg waste was 2,4–3,8% lower than in the control group. The maximum egg mass was registered in the 2nd, 3rd and 4th experimental groups. Egg incision was minimal (2,4%) in the 3rd experimental group. In the control and experimental (1st, 2nd and 4th) groups, these indicators were 3,28, 2,77 and 2,55%, respectively. There was no egg fight in 3 experimental groups, and in all the others it varied within 1,2–1,73%. Shell abnormalities were registered only in groups 1 and 2 (0,97; 1,19%) versus 1,48% in the control group.

The aim of the work was comparative study of the effect of various amounts of tryptophan in the diet of the herds geese on changes in the parameters of protein metabolism in the blood, their eggs laying capacity and the incubation quality of the eggs, as well as the elimination of herbs and their preservation. The research was carried out during the 4-month reproductive period (December-March) on the gray Obroshino breed group of geese in the research enterprise (SE). The experimental farm (Myklashiv) of the Myklashiv Institute of Agriculture of the Carpathian region of NAAS (Myklashiv village, Pustomytiv district, Lviv region). For this purpose, 4 groups of geese-analogues by age and live weight were selected. The control group did not receive synthetic tryptophan supplements for feed additives. The level of this amino acid in this group amounted to 0.16 g per 100 g of mixed fodder. To the diet of the geese of 2-, 3-, 4-th experimental group additionally injected, respectively, 0.04; 0.09 and 0.14 grams of synthetic tryptophan per 100 g of mixed fodder. The conducted studies have shown that increasing the level of tryptophan in mixed fodders of geese with respect to the norms in force in Ukraine from 0.16 to 0.25 g due to its synthetic analogue per 100 g of mixed fodder during the oviposition period increases the hemoglobin level in the blood by 0.6 g %, white blood cells – by 10.2%, ammonium nitrogen – by 10.5%, stimulates fertility and improves the quality of incubation eggs. While analyzing productivity indices of geese, it should be noted that they were the highest in the 3rd experimental group receiving an additive of 0.09 grams of synthetic tryptophan per 100 grams of mixed fodder. The isolation of the caterpillars was the highest in the 3rd group and amounted to 79.3%. An important indicator, as the egg mass was the largest in the 3rd experimental group and was 172.7 grams or 3.1 g more than in the 1st control geese group. The analysis, namely width and length, shows that the most optimal egg shape index was found in the 3rd experimental group (1.8% higher than in the control group). The thickness of the shell of eggs in the experimental and control groups did not change significantly. It has been experimentally proved that the optimization of tryptophan levels in the feed grain of the gray Obroshin genera of geese in the reproductive period has a significant effect on the hematological parameters and the incubation quality of the eggs.

Poultry farming is one of the major branches of animal husbandry, which develops through concentration, specialization and intensification on the basis of poultry plants and poultry farms. The increase in production of eggs and poultry meat is based on a significant increase in the productivity of poultry with a simultaneous increase in its population with a high payment of feed by production and the increase in labour productivity. The purpose of the work was to study the influence of enzyme feed additives in the diets of laying hens on the quality of eggs. The researches have been carried out in PJSC “Poultry plant Chelyabinskaya”, which produces high-quality chicken eggs obtained from the poultry cross “Loman LSL-classic”. The object of study was enzyme drugs produced by Sunzyme – a multi-enzyme drug that includes xylanase, cellulase and mannase activities. The dosage of enzyme drugs in the feed mixture of laying hens was: Sunfyze 5000 – 80 g/t, Sunzyme – 100 g/t. The results of researches show that in the groups that received enzyme drugs in their diet, egg production was higher than in the control group. So, for the entire period of researches the hens of the experimental groups were significantly superior to the control group in terms of egg production per average laying hen. The largest difference was in hens of the 1st experimental group (enzyme drug Sunfyze) – 10,8 eggs; the smallest in hens of the 3rd group (enzyme drugs Sunfyze and Sunzyme) – 5,7 eggs. In hens of the 2nd experimental group compared with hens of the control group egg production was higher by 7,9 eggs. The best indicators of production efficiency have been obtained in the 1st experimental group of laying hens, which were fed with the enzyme feed additive Sunfyze to reduce the nutritional value of the diet according to the matrix.

Compound feed are subject to requirements for their composition, since they use several types of grains that contain anti-nutritive substances that reduce the digestibility and use of nutrients. One of the tasks of domestic poultry farming is to reduce losses by increasing the digestibility and accessibility of feed. Among the most effective ways to solve this problem is to add enzymes to the feed of poultry. The inclusion of enzyme drugs in the composition of compound feed contributes to the inactivation of anti-nutritive substances, which contributes to an increase in the coeffi cient of digestibility of nutrients. The purpose of the work was to establish the feasibility and eff ectiveness of the enrichment of compound feed used in the production technology of chicken eggs with mixtures of enzyme drugs of domestic production of Amylosubtilin G3x, Cellolux-F and Protosubtilin G3x. Three groups of laying hens with 57 heads in each have been formed: a control group and two experimental groups. The duration of the experiment was 420 days. Laying hens of the control group have been received farm compound feed depending on their age. Laying hens of the 1st experimental group have been received compound feed of the control group enriched with the enzymes Amylosubtilin G3x and Cellolux-F depending on the age. In the compound feed of laying hens of the 2nd experimental group enzyme drugs were additionally introduced depending on the age Amilosubtilin G3x and Protosubtilin G3x. Higher egg production rates have been observed in the 1st experimental group – 357,81 eggs, which was 6,48 % higher than in the control group and 1,84 % higher than in the 2nd experimental group. The weight of eggs of laying hens of the 1st experimental group was 1,85 g or 2,97 % more, and the 2nd experimental group was 0,7 g or 1,12 % more than in the control group. The diff erence between the egg weight in laying hens of the 1st and 2nd experimental groups was 1,85 % or 1,15 g. The lowest feed consumption of 1,37 kg for the production of 10 eggs was in the laying hens of the 1st experimental group, which was less than the indicator of the control group by 10,94 and by 4,2 % than in the 2nd experimental group.

The aim of the studies was to conduct a veterinary-hygienic assessment of changes in the eggs productivity of laying hens, after the use of the “Prinarovskaya supplement of fish (DKR)” in their main diet, which is a homogeneous dry mass made from chilled river fish, by-products of fish processings, as well as grain products (wheat bran). The method of production of the additive in-cludes the following steps: grinding, cavita-tion heating and subsequent drying of the resulting mixture. The studied supplement contains a number of amino acids, vitamins and minerals, etc. The object of the study were laying hens of the LomannLsn-Classic breed at the age of 131 days. “Prinarovskaya DKR” were introduced into the diet of ex-perimental laying hens: of the 1st experi-mental group 8 g of “Prinarovskaya DKR” were introduced per 100 g of the main ration (RR); The 2nd experimental group - 6 g. DKR to main ration; 3rd experimental group - 4 g. DKR to main ration; the control group was fed only main ration - feed PK1-1G_1227 (GOST: R 51851-2001). A veteri-nary-hygienic assessment of the quality of eggs, obtained from laying hens, when feed-ing a new feed additive “Prinarovskaya” was carried out. We kept daily records of laid eggs by groups, the period of the beginning of oviposition. The egg production were calculated of the initial and middle laying hens , the egg production intensity for 120 days. To assess egg productivity, the weight of laid eggs, the egg mass for a certain peri-od of egg laying, and the feed costs per 10 laid eggs were determined. Organoleptic, physical, and chemical methods were used to evaluate egg quality. Egg mass is an important indicator of egg nutrition. GOST 31654-2012 "Food eggs. Technical conditions ”, as well as the requirements for chicken hatching eggs, the minimum weight of food and hatching eggs (45 g) is indicated, below which the imple-mentation and incubation of eggs is not rec-ommended [1]. In studies, the following indicators were taken into account: large and small diameter of eggs, egg density, egg shape index of laying hens of different groups. To assess the state of the internal contents of the egg after opening, the follow-ing indicators were taken into account: pro-tein mass, yolk mass, shell mass, egg vol-ume. An external examination of the eggs as-sessed the condition of the shell, the pres-ence of cracks, growths and depressions. The study indicates a positive effect of the feed additive "Prinarovskaya" on the egg produc-tivity of birds in all periods of egg laying

Currently, many scientists have proven the positive influence of feed additives on the productivity of different types of farm animals including bees since feed additives have a positive effect on the honey productivity of bee colonies and the quality of queen bees. The purpose of our work was to identify the effect of probiotics on the background of the dietary supplement Eracond on the acceptance of larvae and the weight of infertile queens. The scientific and economic experiment has been carried out on bees of Bashkir breed in an apiary located in the village of Nekrasovka in the Kartalinsky district in the Chelyabinsk region. Three groups of queen-rearing colony have been formed three in each. In the 2nd and 3rd experimental groups against the background of dietary supplement Erakond (50 mg/ kg) have been given: in the 2nd experimental group sugar syrup with Lactobacterin three doses per family, in the 3rd experimental group sugar syrup with Vetom 1,1 at the dose of 50 mg/kg. As a result, all the additives in the 2nd and 3rd experimental groups gave a positive result. The greatest effect on all indicators has been obtained with the combined use of 50 % sugar syrup with the addition of Eracond phytopreparation (50 mg/kg) and Vetom 1,1 probiotic (50 mg/kg). Feeding these drugs to queen rearing colonies contributed to the increase in the acceptance of larvae by 23,3 %, compared with the control and by 7,8 % compared with the 2nd experimental group, also had the positive influence on the weight of infertile queens by 11,4 % compared with the control group. The use of Vetom and Eracond contributed to the increase in the egg production of queens by 64,2, 54,9 and 57,0 % compared with the control for three accounting periods as well as the increase in the honey collection by 33,83 % or 4,5 kg.

The present experiment was conducted with 144 Shaver 579 egg laying pullets to compare their performances reared on barn and in cages for a period of 16 weeks from 25 to 40 weeks of age. Feed consumption, feed conversion (FC) and egg weight were significantly higher when reared on barn than in cages. However, hen day egg production (HDEP), egg mass, body weight, livability, albumen index, Haugh unit (HU), yolk index, shape index and egg shell thickness did not differ (P>0.05) between pullets under two different rearing systems. Soiled eggs (p<0.01) and shell breaking strength (P<0.05) were higher for the pullets reared on barn than in cages. In contrast, yolk color score (YCS) was higher (P<0.05) in eggs collected from the cage-reared pullets when compared with the eggs of pullets reared on barn. It is concluded that egg laying pullets can be reared either on barn or in cages successfully in Bangladesh condition without any adverse effect on egg production.Bang. J. Anim.

Aim. Study of the influence of new feed additives on the formation of productivity and quality characteristics in the production of various types of raw materials of animal origin. Material and Methods. Zootechnical, biochemical and mathematical methods of analysis were used in the course of research. The obtained digital material was processed using method of variation statistics, considering the Student-t validation criteria, using the Microsoft Excel software package. Results. As a result of the research, the effectiveness of the use of new feed additives "CoreMix" and "Vitazar" in fattening Kalmyk young bulls has been proved. Over the period of the experiment, the absolute increase in live weight of animals of the I and II experimental groups, who received the tested feed additives, exceeded the control by 8.9 and 18.5 kg, while the feed consumption per 1 kg of the increase in live weight decreased by 0.4 and 0.7 EKE, profit from sales per head was higher by 696 and 1,690 rubles, and the level of profitability increased by 3.1 and 8.2%. The study of the regularities of the formation of beef obtained from young bulls of the Aberdeen Angus breed, when using the new probiotic supplement "Rodafen" in their diets, showed that at the end of feeding, at the age of 18 months, the pre-slaughter body weight in the control group was 463.9 ± 3.29 kg, whereas in the experimental groups that received the test supplement in different doses, this indicator was significantly higher by 3.7%, 4.7% and 3.9%, respectively. For the purposeful in vivo formation of optimal quality indicators of beef obtained from young bulls of the Kazakh white-headed breed, the efficiency of using extruded feed from insects of the Locusta migratoria (ELM) species has been proven. More heavy carcasses were obtained from the young bulls of the experimental group in comparison with their peers from the control group: the superiority in terms of pre-slaughter live weight was 5.8 kg, or 1.41% (P <0.05), in terms of the weight of a fresh carcass – 5.6 kg, or 2.75% (P<0.05). In terms of slaughter weight, the young bulls of the experimental group exceeded the control by 5.4 kg, or 2.53% (P <0.05). In order to increase the energy of growth and meat productivity of the Simmental young bulls, the expediency of using new feed additives "Valopro" and "Ruprokol" has been proved. The introduction of these feed additives into the diet during the rearing period made it possible to obtain a live weight of 439 kg, one kilogram of which contains 403 g of muscle tissue and 429 g of edible parts of the carcass, which is 5-9% higher than in the control. It has been experimentally proven that when fattening large white pigs up to 100 and 120 kg of live weight, it is necessary to maintain the amino acid content at an optimal level by introducing synthetic amino acids, which provides an increase in live weight gain and a decrease in the age of fattening. For the purpose of the intravital formation of high-quality mutton obtained from the Edilbaev breed of rams in the arid Trans-Volga region, the expediency of using a new feed additive containing organic iodine, selenium and silicon in the diets of young sheep has been proven. To improve the quality of rabbit meat, the expediency of using new feed additives based on antioxidants and organic acids has been proven. Conclusion. The expediency of using new feed additives in the production of beef, pork, lamb and rabbit meat has been proven. The use of the proposed feed additives had a positive effect on the feed intake and digestibility of feed, the formation of optimal quantitative and qualitative characteristics of the raw materials obtained, and an increase in the profitability of production.

Relevance and methods. The article assesses the effectiveness of the use of herbal feed additives "Zigbir" (which is positioned as a plant hepatoprotector) on the cows diets in the second half of lactation, how it influence on the digestibility of dietary nutrients, on hfhematological composition of blood serum, on productivity and quality of milk.Results. As a result of research experiment, it was found that the introduction of herbal feed additives into the diet had a positive effect on the digestibility coefficients. So, the concentration of total protein at the end of the period, in the experimental group increased by 5.34 g/l and came into compliance with the physiological norm, the digestibility of organic matter, of crude fat and of nitrogen-free extractives in the experimental group increased by 2.2%, 1.6% and 1.0%, respectively. Although the decrease in the digestibility coefficient of crude fiber by the end of the period occurred in both groups, however, the dynamics of its value in the experimental group was on 3.5% less than the value in the control. The use of the feed additives "Zigbir" in the diet made it possible to bring the indicator of urea concentration closer to the physiological norm, the blood glucose increased by 46.4% and came into line with the norm. The dynamic change of bilirubin in the test groups blood was not as significant as in the control group, the total bilirubin decreased by only 15%, against 36% in animals in the control group. The decrease in milk yield due to the attenuation of lactation in the test group was slower relative to the control group and was lower by 0,6l, the mass of fat share and of protein in the cows milk from the test group was higher by 0.4% and 0.2%, respectively.
