CULTIVATION OF PIGLES TAKING INTO ACCOUNT THE TIME OF WEANING AT LLC "AGROFIRMA ARIANT"
The technology of pork production in LLC "Agrofirma Ariant" of the Uvelsky district of the Chelyabinsk region refers to two-phase. Two-phase technology implies a one-time transfer of piglets during the entire production cycle. The first phase is getting piglets and keeping them with the sow, the second phase is weaning and rearing them. Piglets remain in their pen until they reach a live weight of 25-30 kg, at the age of 25-26 days they are weaned. The sow is transferred to the insemination workshop, and the piglets are left in the same pen so that they are not affected by stress. Piglets are reared with BigDutchman machines. The purpose of the research is to analyze the change in the productive qualities of piglets in the process of their rearing in LLC "Agrofirma Ariant" taking into account the weaning time. To achieve this goal, the productive qualities of piglets were studied at different weaning dates, the reproductive abilities of sows were determined at different weaning times. As a result of the research, it was necessary to prove the economic efficiency of breeding early weaning piglets at the age of 21 days. An experiment was conducted to reduce the timing of weaning piglets from sows from the 26th day to the 21st day. The studies were carried out according to the scheme. The piglets were kept under the same conditions and received the same rations. Weaning on day 26 is the traditional time period commonly used in pig farms. Weaning on day 21 is an innovative approach that should increase cost efficiency and increase the number of farrowings per sow to 2.25-2.3 per year. Studies have shown that reducing the suckling period of rearing piglets by weaning them at 21 days of age compared to 26 days is economically unprofitable, although it is justified, since it leads to a decrease in sucking time, sows do not reduce their weight condition, the number of their farrowings increases to 2.2 per year, which improves reproduction rates.
