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.

Abstract. The purpose of the study is to determine the effect of zeolite honguruu on the growth and development, digestibility and metabolism of geese in the conditions of Yakutia. During the experiment, research methods generally accepted in poultry farming were used. Live weight – by weighing birds, digestibility and metabolism according to the method of VIZH, VNITIP. The scientific novelty of the research was to find the possibility of involving natural zeolite in the feed ration of young goose young in the conditions of Yakutia. For carrying out the experiments, we formed 3 groups of geese of 20 animals in each analogue method. Therefore, we determined the effect of zeolite on growth, development, physiological state, and digestibility of nutrients. The purpose of the research is to identify the degree of safety when using zeolite in poultry farming and to obtain an environmentally friendly product for human nutrition. The use of zeolite contributed to an increase in gross increase in live weight by 14.13 % and 19.22 %. So, the supplement contributed to an increase in average daily growth during all periods of cultivation: in 60–70 days – 7.85 % and 15.24 %; in 70–80 days – by 21.73 % and 28.30 %, in 80–90 days – by 13.61 % and 15.76 %. During the experiment, the control group of geese accounted less than the experimental groups of birds – 14.14 % and 19.22 %. A physiological experiment was conducted to determine the effect of zeolite honurin on metabolism. It was found that the additive contributes to better digestion of nutrients in terms of dry matter by 0.9 % and 1.58 %, organic matter by 0.83 % and 1.38 %, protein by 0.64 % and 0.92 %, fat by 0.84 % and 1.58 %, fiber by 0.33 % and 2.21 %, and nitrogen-free extractives by 0.96 % and 1.42 %. During the experiment, it was found that the nitrogen balance in all geese was positive but had differences in the degree of deposition in the body. So the experimental geese of the experimental groups exceeded their peers from the control group by 3.47 % and 5.56 %, respectively. Thus, the use of zeolite zeolite is positive for the growth and development, digestibility and metabolism of geese.

Since changes in linear measurements and the live weight of animals are manifested in a very multifaceted way, it is difficult to imagine their study and accounting using a single universal method. This problem can be solved by using a variety of methods and techniques for studying the individual development of the body. This article is devoted to the study of the features of growth and development in purebred breeding and interbreed hybridization based on the study of the intensity of live weight growth, the dynamics of average daily increases in relative growth rate and linear measurements of experimental animals.

The purpose of research is increase the efficiency of the use of nutrients for rations by Simmental breed bulls with various doses of Vetosporin Suspension. Bulls were fed by probiotic in the amount of 0.1; 1 and 2 ml per 10 kg of live weight. It has been established that the use of rations including the feed supplement studied, in the feeding of experimental groups, promoted an increase in feed intake. Thus, the young growth of the three experimental groups exceeded the analogues of the control group for the consumption of hay grass by 37-118 kg (1.47-4.68%), green weight – by 31-71 kg (1.74-3.98%). Concentrates, molas-ses, fodder, and salt were given to the animals in the same amount. It can be stated that feeding to the Simmental bulls of different doses of the Vetosporin drug suspension had a positive effect on the digestibil-ity of the nutrients of the diet and their assimilation by the body. It is evident that in animals of experimental groups there is a certain superiority in certain indices over analogues of the control group. In this case, the animals of group I were inferior to the experimental groups by a digestibility factor of 1.03-2.24%, raw fat by 0.43-0.77%. For the rest of the indicators, there was a similar trend. When fattening Simmental bull calves, full-fledged and, importantly, balanced feeding was organized. Taking this into account, the use of probiotic fodder supplement, Vetosporin Suspension, contributed to greater consumption of all types of feed, nutrients and energy by animal test groups. In this case, the greatest effect was observed with the use of an approved additive in a dose of 1.0 ml per 10 kg of alive weight.

The response of calves to varying amounts of whole milk, as revealed by two experiments at the University of Reading farm at Sonning, is considered as a study of growth and development.In the first experiment, which had been carried out between 1944 and 1951, seventy-five Shorthorn calves were divided into three groups (A, B and C) reared on 90, 65 and 40 gal. respectively. The treatments produced significant and prolonged differences in live weight.A second experiment, carried out between 1952 and 1954, consisted of twenty-eight Shorthorn and twenty-eight Friesian calves in four groups (I–IV) reared on 100, 79, 57 and 35 gal. respectively. Very much less response to the treatments was found in live weight, and the effects on thirteen body measurements were even smaller, though still statistically significant. A marked difference in the response of the two breeds was apparent, the Shorthorns showing greater treatment effects in live weight and most of the body measurements.

In order to carry out the planned research, an experiment was carried out on repair young animals of the laying chickens of the «Hayseks Brown» cross from the one day-old age. For this purpose, in the conditions of the farm «Berkut» of the Drohobych district of the Lviv region, an industrial herd of hens in the amount of 10 thousand heads was formed. Poultry was kept in cages with free access to food and water. The temperature and light modes corresponded to the recommended standards and the content met the requirements of the technology. All poultry received a complete food, balanced for all nutrients and biological active substances. We have studied the dynamics of growth and development of chicken egg production of line cross «Hayseks brown» from day age to the age of peak performance. During the experiment, the study of the intensity of metabolic processes in the body of 6, 35, 90, 120, and 150 day-olds, i.e., in critical periods when there is intense growth of feathers and juvenile molten (30–60 days), the beginning of the oviposition (120 days) and the beginning of an intensive oviposition (150 days). In these age periods, the level of soluble proteins, amine nitrogen, and the activity of alanine and aspartate aminotransferases were determined in liver tissues, cuticles of the muscular stomach, gastrointestinal mucosa, gastrointestinal mucosa, duodenum and pancreas. During the growth and development of chickens, there are critical periods associated with intense growth of feathers (21–35 days), juvenile strain (70–84 days) and the beginning of oviposition (119–126 days). The highest protein content was found in liver and pancreatic tissues (11.08–13.8 mg/g), lower (by 40%) in the tissue of mucous membranes of the glandular stomach and duodenum and 4–5 times lower content in the tissue, the cuticles of the muscular stomach of the chicken in all the periods of growth we were studied. The age dynamics of changes in the activity of AlAT and AsAT was uneven in the tissues according to the study. Reduced AlAT activity at the 30-day age, similar to protein concentration, which is characteristic of liver tissue, 12-gullet mucosa and pancreatic of chicken. The results of biochemical studies are related to changes in the physiological state and magnitude of gains. During the growth of repair young poultry, in the critical periods of growth and development, it is necessary to deliberately affect the processes of protein metabolism by enhancing the processes of digestion and assimilation of nutrients and biologically active substances of fodder and the sufficient introduction of free amino acids by the use of exogenous enzyme preparations.

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. Key words: growth, development, gain, ontogeny, measurements, indexes, age changes.

Анализируется воздействие микробиологического препарата «ЭМ-Курунга» на рост и развитие карликовых кроликов первых трёх месяцев жизни. Исследуется влияние данного препарата на живую массу крольчат, гнезда, прирост живой массы, а также на индекс сбитости и показатели крови крольчат. В качестве объекта исследования выступили крольчата пород карликовый баран и карликовый заяц. Проведённые исследования показали, что подопытные животные отличались незначительным преимуществом при оценке прироста живой массы. При оценке живой массы гнезда прослеживается тенденция к незначительному увеличению под воздействием биологически активной добавки «ЭМ-Курунга». Индекс сбитости под воздействием препарата не изменился. Количество эритроцитов и гемоглобина у подопытных животных было выше, чем в контрольных группах. Все полученные данные свидетельствуют, что воздействие препарата на исследованные показатели незначительно и недостоверно. The effect of the microbiological preparation "EM-Kurunga" on the growth and development of pygmy rabbits of the first three months of life is analyzed. The effect of this preparation on the live weight of infant rabbits, nests, body weight gain as well as on the blockiness index and blood values of infant rabbits is studied. The object of the study was infant rabbit of the pygmy ram and pygmy hare breeds. Conducted researches have shown that experimental animals had a slight advantage in assessing the body weight gain. When assessing the live weight of the nest, there is a tendency to slightly increase under the influence of the biologically active supplement "EM-Kurunga". The blockiness index under the influence of the preparation did not change. The numbers of red blood cells and hemoglobin in the experimental animals were higher than in the control groups. All the obtained data indicate that the effect of the preparation on the examined indicators is insignificant and unreliable.
