In the process of monogastric animal feeding, including pigs, the special role is played by the quality of coarse grain crops as they compose 70-75% of swine ration structure. Determination of fodder productive effect on fattening swine was realized in the conditions of the Republic of Belarus. The basis of the analyzed fodder was formed by fodder grain of extra fine grade. Research results showed the following: inclusion of extra fine grade barley (Hordeum vulgare) and wheat (Triticum aestivum) (chosen in accordance with the standard of the Republic of Belarus) into all-in-one mixed fodders SK-26 and SK-31 for fattening swine made it possible to obtain higher productive capacity of the experimental animals in comparison with the identical mixed fodders containing barley and wheat of other grades (chosen in accordance with All-Union State Standard 28672-90); in the experimental groups the average daily weight gain in course of the fattening period was on 34 grams higher, and the average selling weight of 1 head - on 4,1 kg than in the control group. Swine which were fed with the presented mixed fodders with grain extra fine grade showed fewer deviations from the rated value of metabolism (blood serum protein and its fractions, calcium, phosphorus, acid capacity) in comparison with the control groups

Research of possibility of application of sapropel (putrid mud) of the Chervonnoe lake (the Republic of Belarus) in diets of bred and milking sows as one of the ingredients of mixed fodders, as well as the evaluation of its influence of sow development and digestibility of nutritive elements were studied. Application of dry sapropel a source of energy, protein, mineral and vitamin nutritive elements for mixed fodder production rendered the positive influence on sows productive qualities: there was stated the increased number of born piglets on o,5 heads with a higher growing capacity; there was noted the increasing of coefficients of nutritive elements metabolism (crude protein – on 2,7%, crude fat – on 2,9%, free-nitrogen extracts – on 1,3%, and dietary fibre – jn 4,7%) with the simultaneous increasing of nitrogen, calcium, and phosphorous uptake by sows. Nutritional value of the analysed sapropel was 0,23 fodder units and 3,13 MJ of exchange energy per 1 kg of dry matter. Inclusion of 3% sapropel into mixed fodders for pregnant and suckling sows promoted the increasing of quantity of pigs at a birth, body weight of one pig to 3-week age and has ensured young growth with higher energy of growth. Use of sapropel in mixed fodders for sows makes active a metabolism and promotes increase of digestibility of the basic nutrients of a rations

Results of determination of yielding capacity, chemical composition of initial weight and silage quality of forages prepared from the binary mixtures of Japanese millet (Panicum curs-galli var. frumentaceum), millet (Panicum) and saccharine sorghum (Sorghum saccharatum) realized in the conditions of the Republic of Belarus were presented. Research results showed that the binary mixture of saccharine sorghum with blue lupine (Lupinus angustifolius) in ratio of 70% + 30%, respectively made it possible to obtain the highest efficiency (62,4 t/ha of green material, 15,1 t/ha of dry matter, 13,1 t/ha of fodder units). Mixed sowing of millet, Japanese millet and saccharine sorghum with blue lupine surpassed in productivity the single-crop sowing on 15,5-32,6%. It was established, that the silage produced from the mixture of sorghum and Japanese millet with lupine had higher energy and protein nutritive value: 0,86 and 0,98 fodder unit, respectively; 9,77 and 9,92 mJ of exchange energy per 1 kg of dry matter, respectively; 103, 3 and 108,4 grams of digestible protein per 1 fodder unit. High nutritive value and the best palatability of trial silos promoted the increasing of milk yield on 4,4-5,4% in comparison with the control tests. Haylage which was produced from drought resistant crops had high energy nutritive value: per 1 kg of dry matter there was noted 9,40-9,48 mJ of available energy, 0,89-0,94 fodder units with fodder unit provision with 102-114 grams of digestible protein

In the conditions of the Republic of Belarus there was analyzed the efficiency of feeding of a new protein vitamin and mineral additive containing national local protein and mineral raw material sources in diets of 12-16-month old heifers. Instead of sunflower extraction cake the heifers were fed with the protein-vitamin and mineral additive which contained rape grain (Brassica napus), lupine (Lupinus) grain as well as mineral and vitamin additives based on halites, phosphogypsum, phosphate, sapropel and premix in dose of 20-25% by weight as a part of mixed fodders. The additive was used against the background of rations with green mass from a cereal and leguminous mixture - 56-57%, mixed fodder - 36-37%, molasses - 6-7%. In accordance with nutritional value indexes the proposed additive rendered the positive influence on forage consumption, indexes of ruminal digestion, as well as on the morphological and biochemical blood composition. It application made it possible to obtain daily average weight gains of animals at the level of 812-827 grams within forage expenses of 7,0-7,2 сentner of fodder units. Inclusion of the protein vitamin and mineral additive with local protein and mineral raw materials in rations of calves made it possible to lower the mixed fodder cost price on 12-15% and the cost price of 1 centner of gain during the summer period - on 11-13%.

Determination of the optimal doses of selenium inclusion into premix structure for breeding boars for the maintenance of their higher producing capacity was realized in the conditions of the Republic of Belarus. Selenium lack in boar rations caused the degenerative changes in seminal glands, low male germ cells concentration and lowering of spermatozoon motility, which subsequently decreased their producing efficiency. Research showed, that selenium inclusion in premix KS-1 structure in quantity of 30 mg per 1 kg in comparison with premix in 20 mg dose have improved the yielding productivity of mature boars: the average quantity of male germ cells per one ejaculate increased on 17,2%, the average quantity of born pigs from per one sow increased on 4,8%. The additional profit per one boar was on 6,06% higher than in control experiment

Appraisement of new mixed fodder formulas for the fattening performance test was realized in the conditions of the Republic of Belarus by the example prevailing in the country Large White breed. Barley (Hordeum vulgare) proved to be one of the main components in swine feeding in Belarus. Forage wheat in mixed fodders for the fattening performance served a basic energy source and contained less dietary fibre than barley, as well as less concentration of antinutrients which interfere with digestion of rations than others crops (rye, triticale). Soybean and sunflower oil meal were included into analysed mixed fodders as the protein sources. Application of new mixed fodder formulas for fattening control realization according to the technical specifications of the Republic of Belarus 600039106.044 - 2007 was realized by the example of gilts of pigs of Large White breed. Research results showed that new studied formulas made it possible to obtain the higher intensity of swine development indices (on 52-72 grams) in comparison with the traditional formulas of mixed fodders (technical specifications of the Republic of Belarus 06093149.065-2000). New mixed fodder recipes did not render harmful effect on health and safety of livestock. At the same time, the analysed recipes of mixed fodders did not authentically influence the carcass indicators (carcass length, fat thickness, loin eye area, ham weight, slaughter yield)
