Upgraded technology of pigs reproduction, breeding and fattening with elements of stress-free keeping at medium-capacity pig farms

This article presents an experimental design of a pig farm for reproduction, breeding and fattening of 6000 pigs per year. The facility was used for testing an upgraded three-phase AC (?) technology with stress-free elements of pigs fattening. A detailed description of all phases of the technological process is given and the main requirements for this technology are provided. The article presents the main technological parameters which served as the basis for necessary calculations, technological planning and a scheme of a hog house general plan. Graphic models of pigs live weight growth are proposed.
