Technological means of increasing the productivity of pigs

Abstract

Goal. To create a complex of stimulating technological equipment for keeping and feeding pigs, which will make it possible to increase their productivity. Methods. The obtained research results were processed using zootechnical, economic, and statistical Methods. Results. A machine for keeping sows and piglets was developed, the advantage of which was the ability to combine nests for stress-free keeping of young animals after weaning and the formation of new groups for growth, and to improve conditions for feeding and motor activity of piglets. Production testing of the developed equipment showed that the live weight of young pigs at the age of 28 days in the control group was 8.23±0.32 kg, in the experimental group — 8.54±0.38 kg; at the same time, the survival of piglets in the control group was 91.66±2.22%, and in the experimental group — 93.75±1.92%. A universal feeder for piglets was also developed, which contained a bunker and a round trough for concentrated feed, rigidly fixed on a master vertical axis, which was installed in bearing assemblies on a cross-shaped frame. In addition, a lattice container for coarse and green fodder was attached to the outer wall of the bunker, and removable containers with vermiculture were fixed to the stops of the bottom of the trough with fasteners. At the age of 60 days, the live weight of a piglet in the control group was 20.45±0.33 kg, and the piglet kept in such a machine was 24.35±0.43 kg; the survival rate of young animals in the control group was 89.58±1.88%, and in the experimental group — 93.75±1.01%. Conclusions. The developed complex of stimulating technological equipment, which included a machine for keeping sows and piglets and a universal bunker feeder, helped to increase the growth energy of pigs, their preservation, and adaptability.
