It was found that the average live weight of geese at the beginning of the oviposition was (OS – 3% X OS – 3%): goose – 6.10 kg, goose – 7.30 kg, and (OS – 5% X OS – 5♂): goose – 6,30 kg, goose – 7,37 kg. The average weight of OS–3 goose was 39.5 eggs per head, and OS–5 – 41.4 eggs. At the same time, the average weight of eggs in the 1st group was 154.3 g, and in II – 158.5 g. The indexes of the forms in the I group consisted of: the length of the egg – 84.4 mm, the width – 55.4 mm, the index of form 65.6 in the second group respectively – 84.3 mm; 56.3 mm; 66.7 mm. The study of the incubation qualities of eggs indicates that the higher fertility was in the goose of the second group and amounted to 85.3%, which is 0.9% more compared with the I group. It is known that the yield of caterpillars is dependent on fertility and in the 1st group this indicator was 71.8%, which is 4.3% less than in the second group (76.1%). At 9 weeks of age, males of the II group surpassed their peers from the 1st group by chest covering 1.79%., With a body length of 2.08%, and a kilo length of 7.14%. The same tendency was observed in the shoots of the shin and plyusny, so the males of group ІІ in the first indicator dominated the male and group I by 8,19%; in the second indicator males of the II group dominated the males of the I group by 6.68%. At 9 weeks of age, females of group ІІ grouped over their breasts over their peers from the 1st group by 2.40%, with the body length by 3.21%., With the length of the keel – by 2.34%. Length of the leg and shoulders in the females of the 2nd group were the largest and dominated by females and groups I by the first indicator at 5.26%; in the second indicator, females of the second group dominated the females of the I group by 1.08%. Males at all investigated periods had higher levels of total protein in serum than females. It was found that males at all investigated periods had higher levels of total protein in serum than females. Performance indicators of Ohorin gray geese (Group I) consisted of: carcass weight – 39.5 pc. on the head; the weight of eggs – 154.3 g; fertility – 84.4%; deductibility – 71.8%; the live weight of geese in the 9-week-old age is 4.52 kg males and 3.84 kg females; preservation – 90.7%. Obroshinsky gray goose (group II) are characterized by the highest indexes in relation to the first group: for fertility by 4.8%, fertility by 0.9%, output by 4.9%, live weight of geese at 9 weeks of age (males) – 1.99%, (females) by 0.52%, preservation – 2.90%, egg mass – 2.64%. The highest feather-down raw material was obtained at the age of 18 in geese I group. The basic indices of blood of the examined geese were within the acceptable limits of the norm.

We set the aim to study the effect of the blood influx of large gray geese and legart geese breeds on the productive qualities of the obroshyno breed group of geese in the third generation) and the legarts that have been highlighted in our previous publications. With the descendants of these crosses breeding and breeding work was conducted in the direction of breeding and productive qualities improvement. For our research, four groups of 50 birds each were compiled from the livestock of geese, which were kept separately for the breeding and egg laying periods (from January to May) to ensure proper feeding and retention. The average geese live weight at the beginning of oviposition were: females OS – 6.25 kg, OB – 6.35, OS ♀ (OS ♀ x BC ♂) – 6.45, OB ♀ (OB ♀ x legart) – 6.5; males OS – 7.15 kg, OB – 7.35, OS ♂ (OS ♀ x BC ♂) – 7.45, OB ♂ (OB ♀ x legart ♂) – 7.50 kg. The duration of oviposition was higher in purebred geese (groups I and III) compared to domestic geese (groups II and IV). The average oviposition of the group I geese was highest – 41.0 pcs/head and was dominated by the group II geese by 1.2%. The weight of OS of geese of group III amounted to 40.6 pcs/head and was dominated by local geese of group IV by 2.9%. However, domestic geese (groups II and IV), by weight of eggs, outperformed purebred geese (groups I and III) by 2.1 and 4.5%, respectively. The study of incubation qualities of eggs shows that the fertilization in purebred AB and OS geese (groups I and III) was 83.9% and 83.0%, and the analogues from II and IV groups prevailed by 0.4 and 0.5%, respectively. The higher hatchability of the geese was in hybrid geese (groups II and IV) than in purebred OBS and geese OS (groups I and III). On the basis of the conducted researches the following conclusions were made: 1. The productivity of geese AB of the breed group (group I) is characterized by the following performance indicators: oviposition – 40.6 pcs. per head; egg weight – 153.2 g; fertilization – 83.5%; deductibility – 71.8%; live weight of geese at 9 weeks of age – males 4.05 kg, females – 3.67 kg; conservation – 87.0%. 2. Local geese of OB x legart (group II) had lower productivity rates: by 2.9%, they had a low fertility rate of 0.5%; fertility – 1.5%; live weight of geese at 9 weeks of age: males – 6.7%, females – 4.6%; conservation – 2.0%; at higher egg mass by 2.1%. 3. Geese of the OS of the breed group (group III) are characterized by the following performance indicators: oviposition – 40.6 pcs. per head; egg weight – 153.2 g; fertilization – 83.0%; excretion rate – 71.0%; live weight of geese at 9 weeks of age – males 4.05 kg, females – 3.67 kg; conservation – 87.0%. 4. Local geese OS x ВS (group IV) are characterized by lower indicators, respectively: with a yield of 2.9%, higher fertilization – 0.5%; with a yield of 1.5%; live weight of geese at 9 weeks of age: males – 6.7%, females – 4.6%; conservation – by 2.0%; at higher egg mass by 4.5%.

Abstract. The article presents study outcomes of the natural egg incubation of the high-productive meat cross Cobb 500 under brood hens of the Bantam breed, as well as indicators of the subsequent offspring growth. The purpose of research is to obtain data on the success of natural egg incubation and the subsequent offspring growth of meat cross-breeding of chickens to determine the practicability of studying the parameters of natural incubation with modern technical means, to identify the most important parameters of natural incubation and to develop new temperature conditions for artificial incubation. Method of research. The research was conducted in 2019 on the basis of the hatchery “Galichya Gora” of the FSBEI of Higher education “Voronezh State University”. The brood hens were kept in laboratory conditions in separate coops. Each of the 3 brood hens was laid with 4 eggs of the Cobb 500 cross from one batch. The scientific novelty of the research lies in the fact that the results of natural incubation and the indicators of subsequent offspring growth were studied for meat cross of chickens, to which natural incubation was not previously applied. Video monitoring of the incubation process has allowed to establish a significant motion activity of the brood hens during the incubation process. Results. As a result of the study, it was found that the decrease in egg mass during the incubation period is 12.1 ± 0.20 %, the average weight of the chicken from the initial mass of the incubation egg is 71.2 ± 0.34 %. The offspring was evaluated at 9.8 points according to the Pasgar©Score system. On the 40th day, the live weight of broilers was 2471 ± 19.4 g. Based on the study, it was concluded that natural brooding provides high incubation rates and offspring quality of high-productive meat cross Cobb 500. The practicability of studying the parameters of natural incubation of meat cross eggs with modern technical means is established.

A total of thirty-four Czech Fleckvieh (CF), Charolais (CH) and Charolais × Czech Fleckvieh (CH × CF) bulls with an average weight of 284 kg were included in the experiment and fed ad libitum two mixed diets: MS (based on maize silage) and LCS (based on legume-cereal and lucerne silages) with different concentrations of dietary energy until slaughter at the target live weight of 600 kg. The CF bulls consumed more dry matter (DM) of feed daily than the CH bulls (<i>P</i> < 0.05) and gained weight less efficiently than the CH × CF and CH animals (<i>P</i> < 0.01) during the entire experiment. The killing-out percentage was lower in the CF than in the CH × CF and CH (<i>P</i> < 0.05). The CH bulls received a higher score for carcass conformation and a lower score for carcass fatness (<i>P</i> < 0.01) than the CF bulls, had lower proportions of kidney and cod fat (<i>P</i> < 0.01) than the CH × CF and CF bulls, and produced the highest percentage of high-priced meat (<i>P</i> < 0.05) and the lowest percentage of separable fat (<i>P</i> < 0.001). The bulls on the MS diet were younger than the others at the end of the experiment (<i>P</i> < 0.01), gained weight more rapidly (<i>P</i> < 0.001), consumed less DM (<i>P</i> < 0.001) daily, utilized nutrients more efficiently over the entire experimental period (<i>P</i> < 0.001), and had a higher proportion of internal fat than the LCS bulls. It can be concluded that purebred CH bulls were superior to the other breed groups in most of the traits observed. The intensive diet based on maize silage increased average daily gains, reduced the time needed to achieve the target slaughter weight, and improved the feed efficiency of bulls.

Objective measurements and subjective evaluations of the eating quality of semitendinosus (ST) and longissimus dorsi (LD) roasts were determined for 32 young (12 to 22-mo) purebred Hereford bulls (four groups of eight) fed a high concentrate ration free choice and slaughtered at average weight of 377 kg for group I, 565 kg for group II, 624 kg for group III, 682 kg for group IV. Intramuscular fat as determined by ether extract increased with increasing slaughter weight. Slaughter weight had no effect on most eating quality characteristics evaluated. Although some differences in palatability were determined they were not large enough to be of practical significance. There was a tendency for panelists to rate the texture (grain) of both types of roasts from slaughter weight groups I and II as superior to the texture of comparable roasts from slaughter weight groups III and IV. In addition, panelists frequently noted the presence of fat in the heaviest (group IV) samples. For ST roasts, residual connective tissue differed significantly between group I and the other weight groups which were similar. There was a slight trend toward increased percent cooking losses with increased slaughter weight but differences were only statistically significant for drip loss of ST roasts. Objective measurements of juiciness (water-holding capacity) and tenderness (Warner Bratzler Shear, Kramer Shear) supported the findings from sensory evaluation. These studies provide evidence that slaughter weight of young Hereford bulls over the range of 377 to 682 kg and 12 to 22 mo of age had only minor effects on cooking and eating quality characteristics, with all the beef samples tested rating moderately desirable to desirable.

The purpose of research is increase of beef productivity and beef quality of Simmental calves at introduc-tion in a diet of feeding different doses of the drug Vetosporin suspension. Of the half-yearly animals, 40 males were selected and formed into group IV for the experiment. The differences were only in feeding. The young were fed the studied additive Vetosporin suspension. In this case, the supplement was an addi-tion to the basic diet of animals of the experimental II-IV groups. The volume of the additive added was 0.1; 1.0; and 2 ml per 10 kg of live weight, respectively. Control group I, consumed exclusively a diet that does not contain an additive. Based on the results of the experiment at the age of 18 months. The prevalence of bulls of the experimental live weight over peers was observed, which was 4.4-25.3 kg (0.78-4.67%). The study of the studied indicators after control slaughter in the context of groups showed the superiority of bulls of experimental groups in all the periods studied. It is established that at the age of 15 months. The size of the removable live weight of the youngest of the control group was less by 8.0-19.7 kg (1.75-4.29%) than in the animals of the test groups. In this case, the leading position was occupied by the youngest of group III, the prevalence of which was 0.7-11.7 (0.14 -2.51%). It should be noted that after 3 months a simi-lar picture of the distribution of the studied quantities was observed. As for the output of carcass, we can note the following. Outsider among the animals of the experimental groups was the control group. So the bulls of group I were inferior to those who received the additive by 0.7-1.3%. At 18 months, as well as at 15 months, the dominant position was occupied by gobies of experimental groups. It should be noted that among the animals of the experimental groups the leading place was occupied by the bulls receiving the feed additive in a dose of 1.0 ml per 10 kg of live weight, that is, the youngest of the III group.

A study was conducted in order to estimate the sodium requirements of Japanese laying quail (Coturnix coturnix japonica). In this study, we used 280 Japanese quails at 128 days of age, with an average weight of 9 ± 5.2 g, and an egg production rate of 82.3 ± 0.94%. An experimental design methodology was employed, completely randomized with five treatments and seven replications. Each replicate consisted of eight quails, with a total of thirty-five experimental units. The experimental diets were based on corn and soybean meal, and contained five different levels of sodium (0.08%, 0.12%, 0.16%, 0.20% and 0.24%). The diets were isocaloric and contained equal concentrations of amino acids, with an electrolyte balance of 250 mEq/kg. The parameters we evaluated were feed intake (g/quail/day); egg production per quail per day (%); egg weight (g); egg mass (g/quail/day); and feed conversion by egg mass (kg/kg) and per dozen eggs (kg/dz). In addition, we evaluated the composition of the eggs in terms of the absolute (g) and relative (%) mass of the yolk, albumen and eggshell. We also measured the body weight variation (g) and viability (%) of the quails. There were no significant effects (p>0.05) on the described parameters. No nutritional disorders occurred related to the level of inclusion of sodium in the diets. The inclusion of 0.08% sodium in the diet of laying Japanese quails was satisfactory to maintain egg production and quality without losses in feed intake or feed conversion.

The research work provided a solution to the problem of preserving the gene pool of Obroshyn gray (OS) and Obroshyn white (OB) geese, which will improve and enhance the valuable qualities of the original flock of geese, gain the desired economic characteristics and thus ensure the competitiveness of the industry in modern conditions. The research was conducted in the laboratory of small livestock ISGKR NAAS and on the basis of SE DG "Miklashiv". The main method of breeding is the selection and selection of individuals with high productive qualities in order to obtain the same type of bird that would meet the planned performance parameters. Selection work was carried out by individual mass selection, aimed at consolidating the standard for each breed group of traits. Before the beginning of the breeding period, males and females of both groups were individually assessed by the exterior, typical plumage, live weight. It was found that both Obroshyn gray and Obroshyn white geese were well selected for productive characteristics and showed high fattening and meat qualities. All birds are well adapted to the natural conditions of the western region. Body sex measurements (chest circumference, torso length, keel, and metatarsus) were higher in males of the Obroshyn gray breed group of geese. Males at different ages had higher rates than females. Obroshyn gray geese (group I) outperformed their peers from group II in terms of meat qualities, the weight of uncorked and gutted carcass, and yield of edible parts. The pre-slaughter live weight of carcasses of males of group I (OS) was 4722 g and prevailed over peers of group II (OB) by 2.94%, and the live weight of females was 4149 g and was higher by 4.19%. It was found that the difference in the number of erythrocytes in males and females was insignificant and almost does not change with age, and hemoglobin on the contrary - increases with age. Males in all study periods had higher serum total protein compared to females. The lowest rate was in males and females аt 4 weeks of age, however, there was no statistically significant difference between the groups in the number of erythrocytes, hemoglobin, and total protein content.

Observations were made on 79 Nigerian indigenous (NI) and 24 Large White pigs.There was. a, three-month delay, in growth acceleration in NI pigs as compared with LW pigs. Growth acceleration started at 7 and 4 months for NI and LW respectively. Over all ages studied, NI differed markedly from LW in live weight, body length, height, depth and ham dimen­sions but this difference was much less between males than between females_ In NI ;boars serially slaughtered, live and carcass weights doubled between 7 and 10 months of age while dressing percent and carcass length reached peak values at 10 months. Carcass backfat measurements were higher and more consistent at the shoulder than at the loin or rump. Com­bined longitudinal and dissection studies are needed to elucidate the growth curve, the true genetic potential for growth and the body fat deposition pattern in the NI pigs.

One of the most effective ways of removing HM salts that have entered the digestive tract of fattened animals is the technological method of including adsorbent preparations in their diets, which, binding various toxins, excrete them from the body. The study purpose is to develop a method to increase the meat productivity and quality of meat of young cattle for fattening in a technogenic zone by inclusion of ToxySorb adsorbent in their diets with a high content of heavy metal salts in the amount of 1.25 kg/t of compound feed and lecithin in the amount of 10 g/100 kg of live weight. According to study results, it was shown that when these drugs were fed together in the indicated quantities, it contributed to better detoxification of xenobiotics. The calf bulls of experimental group 3 had the best slaughter indicators, as well as the best consumer, sanitary and hygienic properties of meat products.
