Feeding piglets in alive mass of 20 – 40 kg at intensive production of pork

Abstract

The purpose. To study influence of all-in-one feed for piglets in alive mass of 20 — 40 kg with minimum norm of density of calcium and phosphorus and heightened norm of density of lysine, methionine +cystine and threonine upon change of alive mass of piglets in the age of 61 — 90 day and productivity of feedstuff. Methods. Conventional zootechnical and analytical. Results. Use of all-in-one feed for piglets in alive mass of 20 — 40 kg with minimum norm of density of calcium and phosphorus and heightened norm of density of lysine, methionine + cystine and threonine ensures minimum alive mass of piglets in 90-day’s age at the level of 40 kg in the age from 2 up to 3 months at daily average increase 650 g and conversion of 1,8 kg of feed compound for 1 kg of increase of piglets against 650 g and 2,1 kg at use of standard all- in-one feeds. Conclusions. The gained productivity indexes of piglets conform the requirements of intensive production of pork and are characterized by positive economic efficiency.
