Effect of bacterial protein meal grown on natural gas on growth performance and carcass traits of pigs

Abstract

Bacterial protein meal (BPM), a new protein feedstuff produced by bacteria (Methylococcus capsulatus, Alcaligenes aci-dovorans, Bacillus brevis and Bacillus firmus) grown on natural gas, was evaluated as a protein source for pigs. Two growth trials were conducted, one with growing-finishing pigs and one with pigs from weaning until slaughter. In Exp. 1, 18 pigs fed restrictively (26.0 and 109.4 kg initial and final weight) were used to determine the effect of dietary inclu-sion of BPM (0, 60, or 120 g kg -1
