Amosov E.V. - On current issues of animal husbandry development in the Krasnodar region pp. 40-43


Abstract:  The present article is devoted to topical issues of development of animal husbandry in the Krasnodar region. The author examines the positive results achieved by the livestock farmers of the Kuban region by 2016. In the work the analysis of failures and defects that affect the results of operations of animal husbandry farms. The issues of application of the advanced experience in the field of breeding livestock on the territory of Krasnodar region are also being considered. The author believes that it is important to ensure food security of the Russian Federation, because it is a strategic task for overcoming Western economic sanctions and an essential condition to fulfill the goals set by the President of the Russian Federation aimed at import substitution of agricultural products and food products. For the successful solution of these problems, along with further strengthening of the forage and extensive use of the efficient production technologies, the importance lies in the qualitative improvement of herds and breeds of highly productive breeds and systematic improvement of breeding and productive qualities of the existing species. The author believes that in this regard Krasnodar Krai is the leading region of the country. 
Pavlova L., Romanova V.V., Pavlova L.P., Rozhina E. - Distribution and Use of Energy by the Offspring with Different Genotypes pp. 53-59


Abstract: The article is devoted to the processes of the distribution and use of energy by purebred Simmental, Simmental Austrian, and Simmental-Holstein heifers. It was revealed that Simmental heifers of the Austrian selection digested nutrients better than those of other groups. The energy of the digested substances in heifers of different genotypes (purebred Simmental, Simmental Austrian selection, Simmental-Holstein) is 81.6, 82.0, 82.2 %% of the digested energy and 55.75, 58.0, 53.2% % of the accepted (gross energy) respectively. Based on the nutrient digestibility data, the animals of all groups were under the same conditions. They all were fed two times a day and drank from buckets. The diet of the experimental animals consisted of grass hay (4 kg), oat haylage (6 kg) and mixed feed (1 kg). Experimental heifers were accustomed to the rations under study during the preliminary period. The gross energy of feed was calculated by the formula: HE (MJ) = 23.9 cP + 39.8 cG + 20.1 cK + 17.5 CBEV. A comparative analysis of digestibility coefficients showed that inthe group of the Simmental Austrian heifers, the digestibility of dry matter was greater by 3.31% and 6 , 86% (Р0.99) and 5.8%, crude fiber - by 5.9% and 8.63% and BEV - by 1.75% and 5.08%, compared with those of other groups. 
Nikolaeva N.A. - Metabolism of Cows With Different Genotypes When Using the Grain Molass in the Feed Based on the Analysis of Central Yakutia pp. 60-65


Abstract: The results of the experiment on feeding grain molasses in the diets of cows of different genotypes (Purebred Simmentals, Austrian Breeding Simmentals, Simmental-Holstein Hybrids) are presented. The studies were conducted in the FSUE "Red Star" of the Megino-Kangalassky ulus of the Sakha Republic (Yakutia). The positive effect of grain molasses on the digestibility of nutrients, which contributed to the activation of animal metabolism, was revealed. In the I-experimental group of cows (Simmentals of Austrian Breeding) protein digestibility coefficients were higher by 10.33% than in the control group of cows (Purebred Simmentals) and by 8.57% than in the II-experimental groups (Simmental-Holstein Hybrids). This intensified the metabolic processes of cows and improved the use of mineral feed. The feed and the feed remainders were analyzed at the biochemical and mass analysis laboratory of the Yakutsk Research Agricultural Institute. The results of the research and analysis of physiological indicators have allowed to make the following conclusion: the use of grain molasses in the diets of milk cows has raised digestibility of all nutrients. This is due to the fact that the efficiency of metabolism depends on how efficiently the metabolic energy of the feed is used and transformed in the farding bag of cows which is in many ways determined by the composition of the feed. To increase productivity of milk cows, Nikolaeva recommends to use the 13% grain molass in the diet of cows. According to the author, this will allow to avoid the loss of nutrients and thus economize the feed and increase productivity of milk cows.
