The article contains the experience of the development of the methodology and the computer program for calculation of regional and local systems of pigs hybridization at the example of the Rostov region (Russia). Crossing the GP lines for F1 should be organized in multiplier farm, which may be separate farms and to be part of large commercial farms. For the production of F1 in a multiplier farm, we must breed a purebred specialized paternal and a maternal line, selected on the effect of combining ability. For the successful functioning of the system of hybridization, it is necessary to build a genetic pyramid, including breeding and genetic centers (nucleus farm), multiplier farm, reproducing the baseline. The article gives a detailed calculation of sow population of levels of P, GP, GGP for maternal and paternal breeds of pigs. The program uses user-defined parameters of pigs productivity, of the simulated population, and the parameters characterizing the intensity of selection of young animals. To ensure annual production of 1,822 million pigs in the Rostov region it is necessary to provide the availability of brood stock in the amount of 89 thousand heads, 6 800 heads in the structure of grandparent flocks (GP), 730 heads in the structure of the Grand-Grand-parent stock (GGP), excluding sows second maternal and paternal breeds

The article provides an overview of the results of experimental works of the authors on the use of different methods of fractionation of Lucerne juice to obtain feed additives

The problem of industrial poultry farming is the emergence of a growing birds’ arthritis. Inflamed joints are usually seen in poultry and accompanied by the inability to take food and water. The most characteristic of this problem in broiler chickens, young chickens of egg cross, i.e. birds of a short period of use. This is the reason for their rejection of the herd. Culling chickens are 10%, which furthermore reduces the total amount of livestock and leads to a reduction in the cost-effectiveness of growing birds. The analysis of our data gives a reason to believe that the main reason for culling poultry is acute inflammation of the joints or arthri-tis. According to the authors to ensure optimal rearing program, which should include the prevention of premature retirement of birds not only due to infectious diseases, but also the prevention of metabolic disorders and the exclusion of factors that could cause disruption of immunological reactivity. Currently, this program needs to be improved, which is particularly important in relation to vaccine pre-vention

Results of the use of plant protein feed additives containing pumpkin paste and soybean seeds of different varieties for quail are presented in the article. It was established that the use of such additives on the basis of Valens soybean allowed to receive higher growth parameters than groups treated with Vilan soybean additive

The article is concerned with the use of functional feed additives from pumpkin fruits and alfalfa juice for the poultry industry. In the study of laying hen it has been found that the use of a feed additive in-creased pumpkin paste content in serum and egg yolk carotenoids is more than two times, and the concentration of vitamin A in these tissues increased slightly, not exceeding 20%. Livability and productivity of poultry increased and average expendable fodder per head per day decreased. Economic calculation showed that the use of pumpkin paste reduces the cost of production of eggs. The use of alfalfa juice coagulates in diets for broiler chickens resulted in an increase in the concentration of carotene in the liver by 22,7-46,8% relative to control. The juice addition also increased the content of vitamin A in the liver by 27.9%, increase the safety and efficiency of the bird. The authors draw certain conclusions from experiment results that the use of functional additives in poultry from the fruit of pumpkin and alfalfa juice is an alternative to synthetic vitamin preparations and produce a more environmentally friendly products

This review contains the information about the role of annelids in maintaining soil fertility. Recommendations based on authors’ experience and scientific literature are given for vermicultivation, biomass use of Californian worms in animal husbandry and vermicompost use in crop production. Furthermore, detailed description of the methods of cultivation of worms is given

The work on the development of technology for production of feed additives from soybean seeds and fruits of pumpkin has shown that the use of sodium bisulfate and lactic acid bacteria provide a high content of carotene in pumpkin paste (948 mg / kg and 819 mg / kg, respectively), and grinding soy before drying protein and vitamin supplements raises safety of carotene without destroying the urease

It was established that water absorption of soybean seeds does not depend on the variety. And in the beginning it has an active character, providing the increase in mass of seeds on 80-140% after 12-14 hours. Subsequently, hydration intensity decreases and mass reaches 110-160% of the original. Electroactivated water increases the level of hydration in comparison with tap water (anolyte – 10-18%, catholyte – 5-9%). Furthermore, in the process of germination of soybean protein content increased by 4-12% and fat – 7-16%. Inhibitor content thus decreases by the same amount, and does not depend on the variety. Thus, consideration of the varietal characteristics of soybean seeds during germination allows how to reduce energy consumption for processing and to reduce the degree of destruction of nutrients

In the work, we have presented the information of elaboration of a manufacturing process of Mycocel feed additive with the cellulolytic activity for poul-try industry. Manufacturing process includes follow-ing steps: stock culture maintenance and storage of Trichoderma lignorum 81-17, growing fluid culture of microscopic fungus in sucrose yeast extract me-dium, feed additive with cellulolytic properties out-put and quality control, packaging, storage and disposal of waste. We have shown that the Mycocel is non-toxic feed additive for protozoa and warm-blooded animals (laboratory mice and quails). This study demonstrated total population livability in the experimental group with feed additive. Quail body-weight of experimental group was higher by 6% as compared to the control and feed consumption per 1 kg of live weight of bird was 3,58 kg, 7,5% lower than the control

Based on the analysis of 422 samples of compound feeds and grain for processing of different farms of the Krasnodar region, we have established the level of their natural mycotoxin contamination and also identified prevailing combinations. Regularities of the frequency of contamination have been presented as well
