The article presents the results of cross-breeding of mountain cattle with Russian polled breed. The growth and development of the crossbreed and purebred bull-calves of these breeds in the mountainous province of Dagestan have been studied in a comparative aspect. Efficiency of highland pastures use by crossbreed animals in comparison with pure-bred mountain peers has been established. The young cattle was grown according to the technology of meat cattle breeding “cow — calf”. In ablactation, the crossbred bull-calves had a living weight of 191.3 kg versus 159.3 kg in peers of mountain cattle. This figure was higher by 32.0 kg or 20.1% compared to purebred bull-calves of mountain cattle. At 12 months of age, the crossbred animals were also superior in living weight in comparison of young mountain cattle by 40.1 kg or 18.4%. According to this indicator, the advantage in crossbred animals at 15 months of age remained. The live mass of crossbred bull-calves at 18 months of age equaled to 399.5 kg against 332.6 kg of purebred mountain peers, the difference in favor of the former was 66.9 kg or 20.1%. Average daily growth of crossbreed bull-calves during the growing period was 122 grams or 20.8% higher. Young crossbred cattle had a clear advantage in terms of physique. Heavy carcasses with high slaughter yield were obtained from it. The conducted studies indicate the effectiveness of cross-breeding of mountain cattle with Russian polled breed in the mountainous province of Dagestan.

In comparative aspect growth and development, reproductive ability of heifers of Hereford breed at keeping in different rooms at different types of feeding are reflected. Heifers of two experimental groups (2nd and 3rd) in the stable period of maintenance in lightweight premises from birth to 18 months of age on a diet with 15–25 % concentrates, feed costs 2633,3 and 2611,5 K. units (3094,7 and 3019,0 EKE), digestible protein-295,2 and 293,5 kg. it was Revealed that by one and a half years of age, the live weight of heifers of 1–3 groups was 352,20±10,58; 373,70±13,28; 389,30±12,18 kg, which is provided by obtaining an average daily increase of 548–584 g against 475 g in the control group 1 (15,4 and 22,9 %). Economic maturity experienced heifers reached 17–18 months of age, which is 1.5–2 months before the heifers of the control group. In addition, the use of concentrates contributed to the formation of more pronounced meat forms in animals, which distinguish them from their peers of the control group in terms of indices of height, pelvis, downness, bony, broad-bodied. The study of the reproductive function of animals showed that the age of the established sexual cycle of heifers of the experimental groups came 21.4 and 20.6 days earlier than the peers of the control group. The age of fruitful insemination of heifers of the experimental groups is 23.7–40.0 days more than that of the control group peers.

In accelerating the rate of filling the domestic market with meat of domestic production, a pivotal role belongs to pig breeding. To make this industry profitable, it is necessary to take care every day to improve the selection, conditions of housing and feeding of animals. Improving the productive qualities of pigs in order to increase meat production is one of the most important tasks of Ukrainian pig breeding. Pigs are characterized by a high growth rate, due to the accumulation in the body of active, mainly proteinaceous substances, the process of increasing its size and live weight is underway. In the process of growth and development, all economically useful traits are formed. The nature of the growth and development of pigs depends on the genotype, conditions of housing, feeding, etc. Researches of scientists have determined that the linear growth of animals in the process of their development increases at a slower rate than the growth of the living weight, and individual body measurements vary with different intensities. Age changes in the structure of animals are due, to a large extent, to the different intensity of growth of their skeleton at different stages of individual development. In the article it is presented the results of studies of the dynamics of changes in the weight of experimental young animals with optimal and intensive fattening. Experiments have shown that at different levels of fattening up to 100 kg, the animals of breeds of with the Poltava Meaty and the Red White belted had the largest absolute increase, this index continued to increase, and when the animals reached 125 kg, the animals of Myrgorod breed had the smallest absolute increase. Also, changes were made in the linear measurements of experimental animals. The results showed that with the age of the animals the absolute indexes of all measurements increased. The animals of the breed Landrace were superior to their counterparts from other groups along the length of the trunk and the depth of the chest. The chest girth was the largest in the youngster pigs of Myrgorod breed, the animals of Landrace were the tallest at the withers. At an increased level of fattening, the greatest length of the trunk was observed in animals of the Poltava Meaty breed. They also had the highest height at the withers and a small chest girth. Pigs of the Large White breed had intermediate indexes. In terms of the coverage of the brush, there was no significant difference, and the depth of the chest was dominated by pigs of Myrgorod breed.

It is established that milk mares of the Kazakh horse of the Aday breed have on average live weight of 389.2 kg, height at the withers of 139.2 cm, an oblique body length of 142.1 cm, a chest girth of 167.6 cm and a metacarpus girth of 17.5 cm. Mares of the Kazakh breed of the Mangystau population surpass in the live weight and body measurements the peers of Aday offspring. Namely, the live weight was 415.3 kg, the height at withers – 140.9 cm, the oblique body length – 143.4 cm, the chest girth – 170.5 cm and the metacarpus girth - 18.3 cm. In general, mares of the Kazakh horse of the Aday offspring are inferior to the minimum requirements for animals of the elite class in height at withers, the chest and metacarpus girths. At the same time, 90% of mares correspond to the 1 quality class. In stallions – producers of the Kazakh horses of the Aday offspring, the live weight averaged 438.7 kg, and in stud horses the Mangystau population – 449,8 kg. Body measurements in Aday horses were 145.2-147.5-169.8-18.5 cm, in the Mangystau population – 145.6-148.1-172.2-18.5 cm, respectively. Some regularities of growth and development of foals from birth to 30 months of age are established. A scale for the development of young Aday horses has been developed.

The article presents the data obtained as a result of carrying by employees of the Research Institute of sheep and goat breeding, a branch of the FSBSI "North Caucasus FARC", the scientific and economic experience to study the efficiency of a new fodder additive "Organic" on the productive and physiological indices of bull-calves during the completion of growing in the conditions of the farm "Pata" agricultural enterprise in the Karachay-Cherkessia Republic. The statement of the experience and all researches were carried out according to generally accepted methods. In the course of the experiment, the following indices were studied: the chemical compound of forages, the dynamics of a live weight gain in the experimental stock, hematological parameters, control slaughter data, economic indices. Completed researches have shown positive result from the use of the fodder additive "Organic" in bull-calves diets: an increase in the average daily gain of live weight by 25%, a slaughter yield by 1% and a high level of profitability – 27%. Thus, the additional introduction of "Organic" in a diet of young horned cattle in the 2nd experimental group promoted more intensive metabolism, stabilization of a physiological state, increase in productivity and, as a consequence, profitability of beef production. Researches in this direction reveal the latent fodder reserves promoting increase in the productivity of agricultural animals.

Изучены рост и развитие бычков — помесей красной степной с казахской белоголовой породой в равнинной провинции Дагестана. Установлено, что помесный молодняк, по сравнению с чистопородным скотом красной степной породы, имеет более высокую живую массу при рождении на 1,8 кг, или 7,3%. При отъеме в 8-месячном возрасте помеси имели живую массу 210 кг против 187,6 кг у красного степного молодняка, что на 22,4 кг, или 11,9% выше. В 12-, 15- и 18-месячном возрасте живая масса помесных бычков равнялась 291,8 кг, 359,7 и 436,6 кг, соответственно, или на 28 кг, 36 и 45,8 кг больше по сравнению с красным степным скотом. Среднесуточные приросты помесных бычков за период выращивания и откорма составили 760 г, что выше на 12,1% по сравнению с чистопородным красным степным молодняком. После заключительного откорма и убоя помесные бычки дали тяжеловесные туши с хорошим поливом. По массе парной туши они превосходили чистопородных аналогов на 31,3 кг, или 15,6% с преимуществом выхода туши на 2,4%. Убойный выход у бычков опытной группы составил 58,7%, контрольной — 55,8%. От помесных бычков были получены тяжеловесные шкуры массой 27,1 кг, от чистопородных — 21,6 кг, преимущество по этому показателю имели помесные животные 5,5 кг, или 25,4%. Для увеличения производства говядины в равнинной провинции Дагестана рекомендуем скрещивание коров красной степной породы с быками казахской белоголовой породы. The growth and development of bulls of red steppe crossbreeds with the Kazakh white-headed breed in the flat province of Dagestan were studied. It was found that young crossbreed animals in comparison with purebred red steppe cattle have a higher live weight at birth by 1,8 kg or 7,3%. When weaning at 8 months of age, cross-bred bulls had a live weight of 210 kg against 187,6 kg in red steppe young, which is 22,4 kg, or 11,9% higher. At 12, 15 and 18 months of age, the live weight of crossbred bulls was 291,8 kg, 359,7 and 436,6 kg, respectively, or 28 kg, 36 and 45,8 kg more than the red steppe cattle. The average daily growth of cross-bred bulls during the growing and fattening period was 760 g compared to 678 g, that is, they were 12,1% higher compared to purebred red steppe young. After the final fattening and slaughter, the cross-bred bulls gave heavy carcasses with good watering. By weight of the paired carcass, they were superior to purebred counterparts by 31,3 kg or 15,6% with an advantage of 2,4% carcass yield. The slaughter yield of bulls in the experimental group was 58,7%, 55,8% in the control group, respectively, with an advantage in favor of crossbreeds of 2,9%. Heavy skins weighing 27,1 kg were obtained from crossbreed bulls, 21,6 kg from purebred ones, and crossbreed animals of 5,5 kg or 25,4% had an advantage in this indicator. Studies have shown that in order to increase beef production in the lowland province of Dagestan, it is necessary to use crossbreeding of the breeding stock of the red steppe breed with bulls of the Kazakh white-headed breed.

ABSTRACTResults are presented from six trials dealing with aspects of management on the cold ad libitum system of calf rearing using an acidified milk replacer containing over 600 g skim milk powder per kg.Thirty-six calves were housed in pens of six for each trial and were fed through a teat and pipeline from a storage barrel. Acidified milk replacer, pH 5·6, was mixed cold at 125 g/1 and made available ad libitum to 3 weeks. A rationed allowance was given daily, on a reducing scale, over the following 2 weeks with weaning completed at 35 days. A pelleted dry food containing 180 g crude protein per kg, together with water in buckets and barley straw in racks, was available ad libitum throughout. Each trial lasted 8 weeks. Results for the mean of the six cold ad libitum trials involving 216 calves were compared with the mean results of 10 conventional bucket-fed trials carried out separately at the same unit, involving 912 calves. All calves were purchased British Friesian male (bull) calves.Calves on the ad libitum system showed improved live-weight gains of 9·4 kg at 3 weeks, 8·8 kg at 5 weeks and 7·5 kg at 8 weeks, compared with the conventional system. The consumption of milk replacer powder was higher in ad libitum trials at 29·4 kg cf. 12·5 kg by bucket but intake of pelleted dry feed was lower on the ad libitum system at 50·7 kg cf. 71·3 kg to 8 weeks. Calf appearance scores were significantly improved on the ad libitum system which gave the main improvement in performance in the first 3 weeks.

Ad Libitum Intake

Hereford and Angus bull calves were obtained from lines selected for an average of 18 yr for rapid growth on a high-energy diet (concentrate) or a low-energy diet (forage). They were given a typical feedlot diet (70% concentrate and 30% forage) in amounts about equal to 95% of the ad libitum intake and were slaughtered at a liveweight of 500 kg. Effects of breed, or of the selection diet given to the antecedents of the bulls, on rate and efficiency of gain of empty body, carcass, fat, protein, and energy were measured. Selection diet had no effect on rate or energetic efficiency of gain of the empty body or any of its constituents, nor on the distribution of the constituents of the gain between the carcass and the noncarcass portions of the empty body. This suggests that both selection diets exerted the same selection pressure for improved growth rate and feed efficiency when offspring resulting from selection were provided with a common high-energy diet and that either type of diet would, therefore, be appropriate for selecting animals for production systems that use high-energy diets. It was suggested that the main effect of selection was to increase the mature weight of the offspring. Comparing breeds, it was noted that Hereford bulls were heavier at birth, grew more slowly to weaning but more efficiently thereafter, and their carcasses were a smaller proportion of empty live weight than were those of Angus bulls.

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.
