Using protein-vitamin-mineral supplement derived from local sources in feeding young pigs.

摘要

A supplement of 20% meat-bone meal, 20% microbial protein, 30% peas, 26% wheat and 4% chalk was added to the commercial ration found lacking in 5% energy and 26% crude protein but in a 9% surplus of cellulose. For pigs given the original ration and pigs given the supplemented ration (groups of analogous pairs), body weight gain averaged 4.2 and 6.3 kg respectively in days 1-10 of the experiment, 3.7 and 4.8 kg in days 11-20, and 11.21 and 16.2 kg in days 21-30, with group differences being significant.
