As a result of the conducted researches it was determined that replacement of milk in diets for suckling calves with whole milk substitute Komnilakt-50/2101 allows to significantly reduce the price and increase profitability of pedigree heifers growing that corresponds demands of the standard of classification for young cattle of 3 months of age on live weight of 90-105 kg at planned live weight of cows of 500-600 kg

The article deals with the prevention problem of digestive system diseases in pig-breeding and therapeutic measures perfecting for these diseases. In article are given new methods of prevention without using antibiotics

In given article natural resistance of geese during the spring-and-summer period is considered at inclusion in a diet coenzyme B12. Namely, dynamics bactericidal, lysozyme activity of blood of geese, dynamics of phagocytosis activity, the general fiber in blood whey, dynamics of fiber gamma-globuline fraction and reliability of distinction between groups is resulted

The present research deals with slaughter and morphological characteristics as well as physical and chemical properties of meat of young hogs taken off fattening estimated bearing relationship to back fat thickness of sow. The above data have been obtained in the commercial swine production farm specialized in three-way rotational crossbreeding in its breeding programme

In the article showed results of the researches of the influence on productive longevity of cows of such factors, as a linear belonging, a genotype of the father, type of selection are stated. The lead researches have shown, that more longer duration of use characterized the animals belonging to line Siling Trajdzhun Rockit 252803 - 4,5 lactations. Among daughters of various bulls the greatest term of productive use daughters of the bulls the Silach 158 - 5,0 lactations differed. At the maximal deviation in efficiency of ancestors (6001-7000 kg of milk) longevity of their daughters was the greatest and has made 4,18 lactations. The greatest influence on duration of economic use of cows was rendered by specific features of bulls (32,2%) and a linear accessory -12,0%. While the selection variant practically does not influence longevity of animals - a share of influence of 3,7%

In the experiment with swine there was studied the influence of ultra-violet and various doses of narrow-band red radiation on efficiency and safety of animals. It has been established, that efficiency and safety of animal skilled groups in comparison with animals of control group has risen. Use of an ultra-violet and narrow-band red irradiation with frequency rate of inclusion of red light three times has a day allowed to raise average alive mass of young plants of pigs on 2,5 kg or on 9,1% (Р less than 0,01), a daily average gain - on 9,6%(Р less than 0,001) and safety of animals - on 10%

Efficiency of level increase of colostrums' full value and natural resistance of calves at the expense of application additive stimulating immunity a preparation «Erakond» is proved in the article. Optimum doses and ways of application of a preparation are established

It is established, that application of laser radiation of low intensity of infra-red area of a spectrum together with a constant magnetic field (an exposition 180 seconds) promotes correction of immunity of an organism of newborn calves that leads to increase in intensity of growth, and decrease in disease of young growth

On the basis of the data analysis of morphological and biochemical blood traits it was determined that blood indices of all groups of pigs didn't break the limits of physiological norms. Pigs of Canadian selection differ by high metabolism intensity and immunity of organism

Application in diets of producing bulls of the increased doses of vitamins and trace elements promotes the increasing of indexes of their reproductive ability on 6,3-12,4% and natural resistance on 3,3-8,8% during the winter and summer periods, and also allows to receive profit on 1 ruble of expenses 3,7 rubles
