Daily Gain

In dairy cattle breeding, selection and breeding work is widely used in order to transfer the pedigree qualities of parents to the offspring and obtain highly productive young animals. In this regard, in the conditions of «Enbek» LLP in the Akmola region, the growth and development of young Simmental breed depending on the origin was studied. Live weight of Litera line young animals at birth was 33.4 kg, at the age of 6 months-174.9, 12 months-251.8, 18 months-387.1 kg, respectively, Wildfang bull 32.0 kg, 165.5 kg, 251.3 kg, 378.6 kg. The average daily gain between the ages of birth and 6 months was increased. With age, the body parameters, height at the withers, increased from 104.3 cm and 103.5 cm to 125.4 cm and 123.9 cm, respectively, from 6 months to 18 months of young animals. According to the physique indices, we can say that the young Simmental breed is balanced. Only some deviations of the leggy index are observed from the optimal indicators. The index of legginess decreases with age by 7.7%, with indicators of 6 months – by 57%, at the age of 18 months-by 49.3%. The extension index for the period from 6 to 18 months increased by 10.5%, respectively, for 6 months-by 103.3%, for 18 months-by 113.8%. With age and an increase in live weight, the body of young animals lengthens, its width increases, the animal becomes deeper and relatively long-legged. Depending on the origin, we suggest using the Litera bull line, taking into account the growth and development of young animals, and the productivity indicators of bulls.

At the present stage of economic development of the Republic of Kazakhstan dairy cattle breeding should be competitive, highly productive and cost-effective, which contributes to ensuring the country’s independence from imports of dairy products. The formation of milk productivity of future cows begins with the preparation of cows for calving and the purposeful rearing of replacement young cattle, based on the achievements of scientific and technical progress, a systematic approach to the production of high-quality products. The researches have been carried out in the farm “Tauelsizdik” in the Eskeldinsky district in the Almaty region in the Republic of Kazakhstan. According to the results of the research, the average daily gain of live weight in 3 months of the post-embryonic period was 458,9±71,9 g in heifers have reared in narrow-sized pens, and 682,2±44,6 g in heifers have reared in group pens. At 3 months of age the live weight of heifers at rearing in narrow-sized pens has reached 76,5±2,5 kg in narrow-sized pens, and 98,3±1,7 kg in group pens (P < 0,001). The data of the experiment have convincingly shown the effectiveness of rearing heifers in group pens. The live weight of heifers at birth was 36,4±1,1 kg, at one month of age – 54,2±1,6 kg, at 2 months of age the live weight increased to 70,2±2,1 kg, at 3 months of age to 87,4±3,3 kg, at 4 months of age to 116,8±3,5 kg, at 5 months of age to 132,7±4,2 kg and at 6 months of age to 157,4±4,6 kg. The indices of lengthiness, chest, hip-chest and blockiness increased up with age, while the indices of high-leg and overgrown decreased down. For example, the lengthiness index has increased with age from 90 to 97 %, the chest index from 62 to 70, and the high-leg index has decreased from 59 to 54, overgrowth from 109 to 108 %.

For the first time, the rationale of using polystim in the technology of calf rearing in private subsidiary plots, on small and medium farms has been scientifically substantiated and experimentally proved to activate the protective and adaptive functions of the body to the keeping conditions and to more fully realize the biological potential of resistance and productivity. Thus, live weight, average daily gain and growth rate of young cattle of the experimental group were higher by the end of the observation period (180 days) than in the control group: in the conditions of personal subsidiary plots by 6.6 kg, 33.3 g and 0.28, on small farms - by 5.2 kg, 20.0 g and 0.08, and with the technology of keeping on a medium farm - by 4.8 kg, 13.3 g and 0.23 (P<0.05 ) respectively. The dynamics of exterior measurements of animals of all groups were similar to the nature of changes in their live weight and their average daily gain. At the same time, the incidence of respiratory organs diseases and the gastrointestinal tract in newborn calves was reduced to 25-40%, the duration of the disease was reduced by 2.45; 1.31 and 1.93 days (P<0.05-0.001).

The origin of an animal determines its productive and breeding traits. It is well known that in dairy cattle breeding a great importance belongs to sires, especially those belonging to the leading lines of Holstein breed. The productive indicators of heifers and fi rst-calf cows the off spring of diff erent lines of Holstein breed and daughters of diff erent sires have been presented in the article. The researches have been carried out under the environments of specialized enterprises for rearing of replacement heifers and milk production. Diff erences have been found in the daughters of diff erent sires in terms of live weight and milk productivity. Accounting for the weight growth of the daughters of sires has shown that the live weight of heifers between the lines Wes Ideal 933122 and Refl ection Sovereign 198998 was not a signifi cant diff erence. Daughters of sire # 511H11283 of the line Refl ection Sovereign 198998 in all age periods had a live weight, absolute and average daily gain, the growth rate of replacement heifers was higher than the daughters of other sires. At one year of age, their live weight was higher than that of heifers-daughters of sires # 11H11596, # 11H11565 and # 511H11422, respectively, by 4,1 % (P<0,001), 3,1 % (P<0,01) and 5,0 % (P<0,001). The daughters of sire # 511H11283 of Refl ection Sovereign line also had a higher yield of calves – 104,8 %. However, the largest number of heifers (75,7 %) has been obtained from the daughters of sire # 11H11565 of Refl ection Sovereign line. In terms of milk yield, signifi cant diff erences have been found between the lines and daughters of diff erent sires. Higher milk yield was obtained from the fi rst-calf cows of line Wes Ideal 933122 (12361±321 kg) and the daughters of the sire Mogul 11H011757 (13587±328 kg). According to the mass fraction of fat and protein in milk, the duration of the period of open days and the number of inseminations, there were no signifi cant diff erences between the studied groups of animals. Thus, the infl uence of specifi c sires on individual productive indicators of daughters has been established.

Abstract. The availability and use of feed that enters the body of pigs depends on the amount and ratio of nutrients in it. Purpose. To determine the effect of different ratios of structural carbohydrates on pig productivity and digestibility of essential nutrients. Methods. Balance experiments were performed on pigs using the diets with nutrients level that corresponded to the need and the norm, and almost the same content of fiber, which differed in structural composition. Indicators of the content of basic nutrients, crude, neutral-detergent and acid-detergent fiber, as well as the ratio of hemicellulose, cellulose and lignin in it were taken into account. The indicators were determined according to the methods of zootechnical analysis. Results. The chemical composition of various bran, hay flour and prepared rations has been studied. It has been confirmed that the lignin content is the lowest in the corn bran and the highest in the barley one, with the highest amount of hemicellulose, a structural carbohydrate that is best broken down by enzymes. The composition of their carbohydrate-lignin complexes and the ratio of their structural carbohydrates have been studied. It was found that the productivity of pigs using fiber in their diet, which is characterized by 12% higher hemicellulose content and 31% lower lignin one, is 46% more than in the control group. It is proved that the introduction of wheat and barley bran, hay flour in the diets of fattening pigs weighing more than 75 kg is economically feasible, given the structural composition of fiber. The average daily gain will be 672 g with the inclusion in the diet of a mineral supplement that will provide the body of animals with all the necessary nutrients. Conclusions. The productivity of pigs largely depends on the content and composition of fiber in their diet. In the period when the live weight of fattening pigs reaches 75 kg, and by the end of fattening (120-130 kg), it is economically feasible to introduce bran into the diet, which implies mandatory control of the content and composition of fiber.

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.

The article provides experimental data on the study of application of two probiotic additives - “Sitexflor - 1” and “SGOL-1-40”, included at different dosages in the diets for young pigs, on usage of the supplied nitrogen and their productivity. Such parameters were taken into account when forming the groups as: weaning time (60 and 45 days), preliminary feeding the mothers with the probiotic supplements under study during the suckling period. The results, characterizing the piglet productivity in case of application of “Sitexflor - 1”, convince that the most effective dose is 30 mg per head per day, which provided an average daily gain of 351 g, which is 7.3% more than the control, primarily due to greater nitrogen retention in the body (by 9.91%), but with lower consumption of energy feed units per 1 kg of gain -4.43 (by 11.4%). The results, characterizing the piglet productivity when applying “SGOL -1-40”, reliably confirm its most effective dosage of 2.5% of the dry matter of the diet, which provided an average daily gain of 404 g, which is 15% more than the control, due to greater nitrogen retention in their body (by 4%). Introduction of “SGOL -1-40” in the diet provided a significant reduction in the cost of energy feed units per 1 kg of gain in comparison with the control by 14.3%. The nitrogen balance in the body of young pigs was positive in both experiments, but the amount of nitrogen retained in the body was different. At the same time, even a greater amount of deposited nitrogen in animals in the first experiment did not allow to achieve the expected live weight increase, and in the second experiment, on the contrary, even surpassed it. Such data indicate that the supplied nitrogen with a diet enriched with a probiotic supplement was more effectively used in the body, exceeding the physiological level of its transformation into products.

Studies of the structure of the interaction of signs with the help of factor analysis is based on the idea of the complex nature of the phenomenon being studied, expressed in the interdependence of individual signs, determined by “internal” hidden causes, forming the specifics of a property, quality. We used the factor analysis method to study the producers’ assessments of the quality of the offspring and to test their bullsons for their own productivity of the Kalmyk and Hereford cattle breeds. The analysis included material from the work of pedigree reproducers and plants in the Kalmyk and Hereford breeds of the Rostov Region. The total number of animals included in the treatment was 96 manufacturing bulls and 272 sons bulls. As a result of the studies, the proposed breeding indices on one basis are quite suitable for the preliminary selection of bullcalves in commodity farms or in pedigree farmers for breeding beef cattle. In order to get a final assessment, we compiled new breeding indices, including two (live weight at 8 and 15 months, live weight at 15 months and average daily gain from 8 to 15 months), as well as three characteristics (live weight in 8, 15 months and average daily gain). These signs are objective, easy to account. According to the estimates obtained for individual bull-sons, it is possible by summing up the values of new factors to identify the bulls’ assessment of the quality of the offspring. Analysis of assessment materials is characterized by high reliability (P > 0.999).

The article is devoted to the study of the intensity of growth and development of quails us-ing a nanostructured preparation. The object of the study was the Texas white quail (n = 45), at the age of 10 days, which were divided into 1 control and 4 experimental groups. Birds from the exper-imental groups were given a complex preparation in various doses and forms to the main diet, con-sisting of compound feed DK-52. It was found that birds are intensively gaining live weight in the first 28 days of feeding. The average daily gains in live weight increased in quails from group 1 by 8.3 %, group 2 – 12.9 %, group 3 – 3.8 % and group 4 – 24.9 % compared with birds of the control group. Starting from the 35th day, there is a decrease in the average daily gain. The best results for both 28 and 56 days were shown by quails in group 4, which received a complex preparation at a dose of 1 % of the diet weight.
