In the first time has been lead the ecological monitoring of sources of water supply of a pig-breeding complex and adjoining human settlements on seasons of year and to develop a method of improvement of water quality for giving to drink pigs. Scientific novelty consists that for the first time in Belarus ecological monitoring of sources of water supply in the conditions of a pig-breeding complex and human settlements adjoining to it is made. Influence of large pig-breeding object on quality of water of the occluded water sources is studied. It is positioned microbial contamination waters depending on remoteness from cattle-breeding object and a season of year

Division of selection area at rest and feeding areas and setting the straw bedding norms for heifers of 6-12 months of age as 2 kg per animal daily, 13-16 months of age – 3 kg and 17-25 months of age – 4 kg promotes increases of average daily live weight gains compared to traditional technological solutions and norms at 6,4%, hemoglobin content – at 3,7%, erythrocyte quantify – at 5,6%

In the article concept and essence of aquaponic systems for production of ecologically clean agricultural production without waste technologies is set forth. A degree of a level of studies of the given рroblem in the countries of the Europe, America, Australia and other countries is set forth too. The expediency of application of similar systems for fuller use of power resources of plants for production of heat of the electric power, an opportunity of production of agricultural production in urban conditions and on the limited ground areas is proved

Rape-cake containing 1,4-1,9% of glycozinolates and 27-30 mMol of erucic acid per 1 kg of dry matter may be implemented in mixed feed KP-1 for calves in amounts of 15% on mass. Feeding animals with mixed feeds KP-1 with rape-cake allows to get the average daily weight gains of 848-865 g at forage spends of 2,49-2,52 forage units per 1 kg of weight gain

Into the programme hen selection of Belarus Autoseksnyj cross there was introduced the indeks of the so-called quality of eggs which is defined by removal defective on quality of a shell of eggs in 30 and 52-week age. The size of variability of an indicator of 16,0-25,4% and hehtability 0,3-0,4 allows to lead selection on increase in an exit of qualitative eggs. Influence on quality of eggs with defects of a shell of age of hens, intensity eggs, weights of eggs, a linear accessory is established

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 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%

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

Usage of preservatives Kormoplus 1 and 2 lets us produce the silage of a highest quality and raise dry substance integrity at 8,7%, protein - at 12-9,4%. The researches determined that cereal silage, prepared with supplement Kormoplus 1 and 2, lets us raise digestibility of dry substance at 5,5% and 3,7%, organic substance - at t 5,5 and 4,0%, fiber- at 16,5 and 15,0% and raise nitrogen sediment at 17,4 and 20,8%. These forages didn't have any negative influence at health and biochemical performance of cow blood
