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

Bacterial protein meal (BPM), a new protein feedstuff produced by bacteria (Methylococcus capsulatus, Alcaligenes acidovorans,Bacillus brevis and Bacillus firmus) grown on natural gas, was evaluated as a protein source for pigs. Twogrowth 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 inclusionof BPM (0, 60, or 120 g kg-1), replacing protein from soybean meal on growth performance and carcass traits. Adding60 and 120 g kg-1 BPM to diets reduced (P on growth performance during the finishing or overall periods. Both levels of BPM improved amino acid and lysine utilization(P contrast, both levels of BPM tended to increase carcass meatiness. In Exp. 2, 48 pigs (11.4 and 107.2 kg initial andfinal weight) were used to evaluate increasing levels of BPM (0, 50, 100, or 150 g kg –1) on growth performance and carcasstraits from weaning at 34.5 days of age until slaughter. Bacterial protein meal reduced ADG (linear P the period from weaning until five weeks post weaning and during the period from weaning until slaughter. Increasinglevels of BPM tended to increase overall feed/gain. Also, BPM increased backfat firmness (linear P percent carcass lean (linear P fat area in cutlet (linear P with the control. In conclusion, up to 120 g kg –1 BPM in diets for pigs from 26 kg live weight until slaughter hadno adverse effect on overall growth performance or carcass lean or fat content. Up to 150 g kg –1 BPM to diets for pigsfrom weaning until slaughter reduced growth rates during the piglet period and increased carcass fat content due tomarginal dietary lysine levels. Bacterial protein meal gave a dose dependent improvement in the utilization of total aminoacids and lysine and the quality of back fat determined as fat firmness and fat color

Technical and Economic Performance of Alternative Feeds in Dairy and Pig Production

A major cost component in livestock production is feed, which suggests improved feed efficiency as a promising strategy to improve both competitiveness and environmental sustainability. This study has investigated the technical and economic efficiency of using two alternatives to the standard feeds in livestock production in Norway. Data was generated from two controlled feeding experiments involving dairy cows and finishing pigs. In the dairy cow experiment, grass silage optimal in protein content was compared to silage lower in protein content in rations to moderately yielding cows. In the pig experiment, imported soybean meal was compared to rapeseed meal in diets to finishing pigs. From Data Envelopment Analysis, we did not find significant within group as well as between group differences in technical efficiency of animals under different feeding strategies. Under the assumptions of the study, however, a feeding regime based on low protein silage was found to be cheaper (–9% to –10%) for moderately yielding dairy cows, suggesting that Norwegian milk production could be based on the low protein silage fed ad libitum. On the other hand, despite reducing feed costs, a feeding regime based on rapeseed meal was less profitable, although statistically insignificant, than soybean meal for finishing pig production. Therefore, the nutritional value must improve and/or the price of rapeseed meal drop before it becomes an economically acceptable replacement to soybean meal.publishedVersio
