Energy Sources Spends on Growing Pigs at Weaning at Industrial Complexes in Winter Period

Abstract

Researches carried out on piglets at growing area determined that productivity and safety of young animals in winter period at all the studied variants of reconstruction was higher than that of kept in typical rooms with traditional management technology. The most effective of the studied variants of reconstruction was the one where the hanging ceiling was made of siding (PVC panels) and was 2,2 m height, the air intake was done from the gallery via 2 openings (0,4 m x 0,4 m) taking place on the level of floor. Animals of this breed group surpassed animals kept in the typical section on: live weight - at 2,4 kg, on average daily weigh gain - at 31 g (10%), on safety - at 6%. Energy spends counted per 1 c of weight gain went down at 16,06 thousand rubles (2,2 times lower) compared to typical rooms.
