Essay

Object - the industrial technology of pork, male pigs - manufacturers, sows (single, sow in farrow, sow in lactation), young growth of pigs, pigs, pigs without sow. The purpose - to investigate influence extract of processing on the chemical compound and power nutritiousness of a grain of barley, wheats, corn, peas, a soya and lupine; to learn the chemical compound, nutritiousness and digestibility juice of lucerne and products of its processing; to establish optimum amount of input extracts grain forages, juice of lucerne and products of its processing, and also sugar beet in mixed fodders of pigs of different sexual and century groups; to prove optimum terms of absence of pigs from sows at use of nonconventional forages in conditions of industrial technology; to investigate different regime milk feeding sows and to give them a scientific - practical substantiation; to define efficiency feeding nonconventional forages at cultivation of pigs with different weight at birth and absence; To develop practical recommendations for use of nonconventional forages in feeding pigs. Methods - zootehnical , physiological, hematological, biochemical, etological, biometric. Novelty - For the first time theoretically is proved and the effective system of feeding of pigs in conditions of the industrial technology of pork is experimentally proved on the basis of the developed methods of reception of nonconventional forages and effective their ways feeding to male pigs - manufacturers, sows, pigs and young growth at cultivation and fattening. Digestibility nutrients, payment of a forage, parameters of hematology, lethal and meat qualities of pigs for the first time is investigated at cultivation and fattening them on mixed fodders with the different contents of nonconventional vegetative protein and carbohydrate forages. The expediency of use regime milk feeding sows and cultivation of pigs with different weight is experimentally established at birth and absence. The optimum circuit of use of nonconventional forages in feeding male pigs - manufacturers is offered, their positive influence on quality of sperm, fecundating sows and an effective utilization of the frozen sperm is shown. Industrial tests of the developed systems of feeding of pigs are spent and introduced into manufacture in facilities the Belgorod, Zhitomir, Poltava, Vinnitsa and Kiev regions, and also used in educational process and research work. Area - animal breeding.
