The age of farrow in piglets and its effect on the comparative characteristics of hematological, biochemical indices and average daily growth

Abstract

Piglets are weaned gradually, on the first day of weaning the piglets are only allowed to suckle 5 times, on the 2nd day 4 times, on the 3rd day 3 times and on the 4th day 2 times, and in 5th and 6th days only once. On the 6th day after weaning, the sows are removed from the pens and moved to another place, the weaned piglets being left in the pen where they grew for a few days. If the piglets are taken out of the pen on the same day as the sow, they become very agitated, often losing their appetite, with corresponding negative consequences. For efficiency in breeding sows, piglets at 21-28 days or even younger are also often weaned. The study of hematological and biochemical blood indices showed an increase in the amount of erythrocytes. The average daily gain was higher in piglets that were kept in smaller numbers in pens. The participation of the Great White, Durok and Landrace breeds in the given complex plays a very important role in fattening. No abnormalities, illnesses or deaths were reported.
