Adaptation of the rearing boars to low-cost, environmentally safe technology in unheated premises

Abstract

The dynamics of the development of pig breeding in recent years indicates that when housing the breeding stock and rearing young animals in premises with traditional technology and the use of artificial microclimate complicates the technological process of production of pig breeding and creates a number of significant problems. Typical problems for industrial complexes, pedigree plants, breeders and large agricultural enterprises for the production of commercial pork are high production costs and high production costs. The existing systems for raising young pigs have fundamental shortcomings, among them: systems for the removal and disposal of environmentally hazardous liquid manure, microclimate disturbances, crowding in a pigsty; limited movement, slotted floors; frequent change of premises or technology groups; increased stress due to imperfect technology of maintenance and lack of biological adaptation and inadequate care for sows. In this regard, a scientifically and economically sound search for new adaptation methods was needed aimed at increasing the body's stability and maintaining its high productivity at pedigree farms, pedigree producers and various agroformations for the production of pig production. In the materials the results of studies of the adaptation of the boar to the growing conditions and feeding with the introduction in the diet of green hydroponic feed and its impact on their growth and development. The positive influence of the method of differential feeding with the introduction in the diet of green hydroponic feed, when using a multi-technological equipment for single-phase rearing boars in the conditions of low-cost, energy preservation, environmentally friendly technologies long non-replaceable on a deep litter of straw with a sandy base in unheated areas. Key words: single-phase rearing boars, reproductive qualities, hydroponic green fodder, low-cost technology, unheated premises.
