One of the main branches of agriculture in the Republic of Sakha (Yakutia) is productive horse breeding. In this regard, we can use the valuable raw materials that the horse gives due to its high adaptability to local conditions. The development of productive horse breeding in particular dairy horse breeding under the conditions of the Republic of Sakha (Yakutia) would allow providing the population with natural, dietary food and more efficient use of land resources. The purpose of the work is to study the effect of zeolite and zeolite-sapropel feed additives in the ration of mares of Megezhek breed on the milk productivity and quality of kumiss under the conditions of Central Yakutia. Two scientific and economic experiments have been carried out where the influence of zeolite from the Suntar deposit (experiment 1) and zeolite-sapropel feed additives (experiment 2) on the milk productivity and physiological parameters of mares of Megezhek breed has been studied. The optimal doses of the effect of zeolite and zeolite-sapropel feed additives on the profi tability of kumiss production have been determined. It has been found in the first scientific and economic experiment that when adding 0,4 g of zeolite per 1 kg of live weight to the daily ration of lactating mares the level of profi tability of milk production increased to 20,4 %, and when adding 0,5 g per 1 kg of live weight the profi tability index increased to 21,5 %, compared to 13,7 % in the control group. In the second scientific and economic experiment the infl uence of the zeolite-sapropel feed additive on the intensity of digestion and assimilation of nutrients in the mares’ rations has been determined. The analysis of the experimental data indicates a high economic efficiency of using zeolite-sapropel feed additive in the 2nd and 3rd experimental groups of mares, where the level of profi tability of production was equal to 27,34 and 32,33 %, respectively, compared to 16,09 % in the control group.

Introduction. When creating the Simmental beef breed of cattle during many years carried out researches to study the effectiveness of the use of meat Simmentals of foreign selection in crossbreeding with cows of Simmental breed of domestic selection. Were created the herds of the desirable type by breeding "in themselves" animals, that meet the requirements of the target standard, formed a genealogical structure. Now carry out the work with related groups of cattle of the created Simmental meat breed, which are the basis for the creation of further lines, but the growth and development of animals of different related groups have not been sufficiently studied. Therefore, the study problems of growth and development of repair heifers of different related groups has not only theoretical, but also practical importance. The purpose of our researches was to study the dynamics of linear growth and weight development of heifers of different related groups of the created Simmental meat breed. Research materials and methods. The researches was carried out on heifers of different related groups of the created Simmental meat breed in PJSC "Dniprovske" of Boryspil district of Kyiv region. To analyze the growth and development of heifers were formed groups of animals depending on their belongings to related groups of 15 heads in each: I Group – Metz 5290; II – Achilles 369; III – Abricot 58311; IV – Huxla 19223; V – Hercules 8942 and VI – Signal 120. Research results. It was determined, that heifers of the II group, which belong to the related group of Achilles 369, by live weight at all ages of periods surpass to peers. Thus, at 18 months of age the advantage of heifers of the II group by live weight in comparison with to peers of the I, III, IV, V and VI groups was 4.1; 3.0; 5.0; 14.1 and 11.4 kg. In heifers of related groups Hercules 8942 and Signal 120, the coefficients of variability of live weight at birth in which were the lowest, and in the following age periods they little changed, therefore at 18 months of age in these heifers they were the highest, comparison with analogues, and was to 8.4 and 9.2%, respectively. When studying the exterior of heifers of different related groups it was determined, that newborn heifers of the I group, which belong to the related group of Metz 5290, surpass their peers in height indicators. Their the height at the withers and the height at the sacrum were 74.0 and 79.1 cm, which is 0.6; 1.3; 2.1; 3.2 and 2.6 cm and is 0.3; 1.2; 2.9; 3.6 and 3.2 cm more than in analogues of the II, III, IV, V and VI groups, respectively. The best indicators of latitudinal measurements had the heifers of the III group, which belong to the related group Abricot 58311. In heifers of this group the width of the chest was 17.6 cm, width in the hip joints – 21.8 cm, width in the hips – 18.1 cm, and width in the ischial tubercles – 12.6 cm. The depth of the chest and the girth of the chest behind the shoulder blades were the highest in heifers of the I group, which belong to the related group of Metz 5290. They were 32.2 and 79.6 cm, respectively. When analyzing the measurements of heifers at 18 months of age, it was determined, that the height indicators had advantage by heifers of the II group, which belong to the related group of Achilles 369. Their, the height at the withers and height at the sacrum were 124.5 and 129.8 cm, which is 0.3; 1.3; 2.5; 5.3 and 4.2 cm and is 0.9; 2.2; 4.1; 6.6 and 5.9 cm more than in analogues of the I, III, IV, V and VI groups, respectively. The best indicators of latitudinal measurements had the heifers of the III group, which belong to the related group of Abricot 58311, since they had increases of measurements width of the chest, width in the hip joints, width in the hips and width in the ischial tubercles for the period from birth to 18 months of age the highest comparison with peers. Such indicators as depth of the chest and the girth of the chest behind the shoulder blades were highest in heifers of the II group, which belong to the related group of Achilles 369. Their increases of measurements depth of the chest and the girth of the chest behind the shoulder blades for the period from birth to 18 months of age also were highest comparison with peers and were 35.5 and 94.2 cm, respectively. Conclusions. It was determined, that the animals of the related group of Achilles 369 at all ages of periods had a large live weight in comparison with their analogues. The lowest coefficient of variability of live weight at 18 months of age was in heifers of the related group Abrikot 58311 and amounted to 6.5%. Heifers of the related group of Achilles 369 had the highest indicators of the following measurements: height at the withers (124.5 cm), height at the sacrum (129.8 cm), depth of the chest (67.4 cm), girth of chest behind the shoulder blades (173.1 cm) and oblique length of body (146.4 cm). The highest latitudinal measurements were observed in the heifers of the related group Abrikot 58311. Thus, the width of the chest was 49.9 cm, the width in the hip joints was 42.2 cm, the width in the hips was 43.3 cm, and the width in the ischial tubercles was 29.2 cm. Heifers of the related group Metz 5290 had the highest half-girth croup (110.2 cm) and girth of metacarpus (18.4 cm).

The use of clinoptilolite is an effective means of increasing the gain and live weight of calves. The application does not cause difficulties in the methods of introducing the additive to calves. Natural clinoptilolites of various deposits are presented in a wide range on the feed additives market. Aims: The objective of the work was to study the effectiveness of natural mineral clinoptilolite on physiological and zootechnical indicators of growth and development of calves. Methodology: The study was carried out on 39 clinically healthy Holsteinized black-and-white calves selected at random, 13 animals per group. For 85 days, the calves of the experimental group received a basic diet enriched with natural mineral clinoptilolite to increase the efficiency of growth and development at a dosage of 25-50 and 50-100 g / head / day. Blood samples were taken from the jugular vein at the end of the supplement feeding (n = 5) for physiological, biochemical and immunological studies. Results: In the course of the study, it was found that in the experimental groups there were higher gains in live weight by 7.3 and 4.7% in comparison the control, and low feed costs per 1 kg of gain. Feeding clinoptilolite promoted an increase in the concentration of Ca in the blood of calves of the dairy period by 14.2% (p <0.05), an increase in phagocytic activity by 4.87 (p <0.05), the phagocytic number was higher by 0.20 (p < 0.05) units. Conclusion: The totality of the information presented confirms the physiological adequacy for calves to the introduction of natural mineral clinoptilolite in the indicated dosages.

Crop maturity at harvest affects the intake potential of maize silage. A short feeding trial with young beef heifers (Browne, Bryant, Beever and Thorp, 1998) identified a significant depression in intake when low DM silage was fed, yet no significant effect on live weight gain was recorded. The objective of this experiment was to determine if these results were repeated in a longer intake study using finishing beef cattle and to examine the effect of maize maturity on carcass quality.Forage maize was harvested at three stages of maturity (LOW, MED and HIGH) during September 1997. At each stage of maturity, the crop was cut and ensiled in a separate AgBag during one day, without the use of an additive. The respective silage DM concentrations were 297, 339 and 393 g/kgFWt.

Currently, the existing literature sources on the use of feed additives “Tetra+” and “Glimalask” do not fully reflect the data on the comparative study of their infl uence on the physiological state, meat productivity and pork quality of fattened young pigs. Under the conditions of the Lower Volga region comprehensive researches were carried out in a comparative aspect to improve meat productivity and pork quality through the use of feed additives “Tetra+” and “Glimalask” in the diets of young pigs on fattening. The purpose of the work was to increase the productive and pork quality of young pigs on fattening due to the use of feed additives “Tetra+” and “Glimalask” in their diets. The research was carried out in the period from 2012 to 2019. The experimental part of the work took place under the conditions of the stud farm named after Lenin in the Surovikinsky district in the Volgograd region. The object of research was young pigs of Large White breed. The positive influence of feed additives on the digestibility and use of nutrients in diets, meat productivity and pork quality, physiological indicators and economic effectiveness of pork production has been proven. It has been found that the level of profi tability of pork production was higher in the experimental groups in comparison with the control group by 5,03 and 4,48 %, respectively. At the same time the highest effectiveness has been obtained from the animals of the 1st experimental group, which received the feed additive “Tetra+” in the diet, which allowed to increase the live weight gain by 6,74 %, the level of profitability by 5,03 %. Thus, the feed additive “Tetra+” was the most effective.

One of the ways to increase meat resources is to improve the condition of livestock on farms in the Russian Federation. This is due to the fact that when the fatness of the animal increases, the meat yield in the carcass increases. The purpose of the researches was to establish the features of the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed. In order to achieve this purpose two groups of steers-analogs of Hereford breed (control and experimental) at the age of 6 months per 10 head in each have been formed. The time of the experiment was: the preparatory period of 22 days and the main one 275 days. Steers of the control group have received the main farm ration, and steers of the experimental group have received the main ration and feed protein additive Biovitel for 30 days with 10-days interval at the dose of 100 g per head during the sixth month. The results of researches on the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed have been refl ected in the article. The addition of the feed additive Biovitel to the main ration of the experimental group of steers helped them to achieve a higher live weight and higher average daily gains under the same environments of feeding and housing in all age periods. By the end of the experiment (15 months) the experimental group of steers have reached the live weight of 430,2 kg, which was higher by 19,9 kg or 4,9 % compared to the control group of steers. In order to improve the quality of beef and increase its production more intensive rearing of steers of Hereford breed with the use of feed protein additive Biovitel has been justifi ed. The recommended dose is 100 g per head. This dosage allows you to achieve the average daily gain of 967,5 g and the average live weight of 430,2 kg by 15 months of age, reduce the prime cost and increase the profi tability of beef production.

Изучены рост и развитие телок помесей горского скота с русской комолой породой в горной зоне Республики Дагестан. Доказана эффективность использования высокогорных пастбищ крупным рогатым скотом. Установлено, что молодняк помесных животных по сравнению с аборигенным скотом имеет более высокую живую массу при рождении на 1,2 кг, или на 6,9. При отъеме в 8месячном возрасте помесные телки имели живую массу 156 кг против 140 кг у аборигенного горского молодняка, что на 16 кг, или 11,4 больше. В 12, 15 и 18месячном возрасте живая масса помесных телок составляла 220,2 кг, 267 и 321,4 кг, соответственно, или на 27,1 кг, 36,4 и 45,1 кг больше по сравнению с горским скотом. Среднесуточные приросты помесного молодняка в среднем за период выращивания телок составили 556 г против 475 г, то есть они были выше на 17 по сравнению с горскими аборигенными телками. Промеры статей телосложения животных тоже были в пользу помесных. Высота в холке у помесей достигала в возрасте 8 мес 85,3 см, в 12 106,5 и в 18 мес 110,5 см, а у аборигенных телок горского скота высота в холке была значительно ниже по сравнению с помесями и составляла 79,8 см, 93,4 и 103,8 см, соответственно. В 18месячном возрасте телки горского скота уступали по высоте в холке помесям на 6,7 см, или на 6,4. Исследования свидетельствуют об эффективном использовании высокогорных пастбищ Дагестана помесным скотом. Такой подход к ведению мясного скотоводства в условиях горной зоны Республики Дагестан позволит увеличить производство дешевой и высококачественной говядины.Growth and development of hill cattle heifers and their cross breeds with Polled Russian breed are researched. Efficiency of utilizing mountain grass is proved. It is ascertained that cross breed young stock live weight at birth exceeds that of native ones by 1,2 kg or 6,9. Cross breed heifers at ablactation had live weight of 156 kg at 8month age versus 140 kg of native ones, which is 16 kg or 11,4 higher. Live weight of 12, 15, and 18month cross breed heifers was 220,2 kg, 267 kg, and 321,4 kg, respectively, which is 27,1 kg, 36,4 kg, and 45,1 kg greater in comparison with mountain cattle. Average daily gain of cross breed animals was 556 g versus 475 g, which is 81 g or 17 higher in comparison with mountain heifers. Shoulder height of cross breed heifers was at the age of 8 months 85,3 cm, 12 months 106,5 cm, and 18 months 110,5 cm, while mountain cattle height was sufficiently lower in comparison with cross breeds and was 79,8 cm, 93,4 cm, and 103,8 cm, respectively. At the age of 18 months mountain heifers were inferior to cross breeds by 6,7 cm of shoulder height, which is 6,4. The study reveals high efficiency of utilizing Dagestan mountain grass by cross breed cattle. Such approach to beef cattle farming provides for increase of cheap and high quality beef production.
