THE RELATIONSHIP OF THE PLACEMENT DENSITY OF FATTENING PIGS WITH THEIR PRODUCTIVE QUALITIES
The studies were carried out in the production conditions of a small farm LLC Agro-Vostochny of the Ust-Kalmansky district of the Altai Territory on cross-fed pigs, whose age ranged from 41 days to 6 months. Hybrid piglets were obtained from crossing large white pigs and landrace breeds. The aim of the work is to study the effect of the size of groups of pigs on fattening on their productive qualities in the conditions of small-scale farming. The animals of the experimental groups during the experiment were in the same conditions of feeding and housing. Rations were compiled according to the norms of feeding, taking into account the physiological state of animals and age. Experimental animals during the study period were clinically healthy. The negative aspects inherent in small and medium-sized pig enterprises can be largely eliminated by transferring them to intensive technology. This significantly increases the efficiency of such farms and ensures the possibility of survival in the face of fierce competition with large suppliers of pork [3, 6, 7]. For small farms and peasant farms, a technology has been developed for producing, growing and fattening pigs to slaughter conditions (TB-2-6). Depending on the technology adopted in the farm, fattening groups form from 10 to 30 heads [9, 4, 5]. It is known that the results of fattening pigs, along with feeding, are greatly influenced by the methods of keeping pigs. Most animals for fattening contain groups. The size of groups, the density of placement and the evenness of animals by body weight are important components of the technology of the group content of fattened pigs [1, 8]. The behavior of animals during feeding, watering and rest, as well as their health and sanitary condition of the machine largely depend on the size of the groups, their composition and the density of the pigs. With regard to small farms, we note that there is not enough experimental material to solve this issue. [2].
