ABSTRACT
Two experiments were evaluated, the efficacy of multienzymes (Natuzyme) in weaned piglets (Experiment 1) and in 3 periods (starter - grower - finisher) fattering pigs. The results from these two experiments supplementation multienzyme in weaned or nursery feed and all whole 3 periods of fattening feed, showed improvement in digestibility of carbohydrate and protein in feed components and remarkable improvement in body weight, daily weight gain, better feed efficiency, lower feed cost per kilogram body weight and increasing in both net profit per head and economic benefit return over those fed the unsupplemented control group. Superior multi-properties effect of Natuzyme improves the digestibility of corn/soya diets, increasing the effectiveness of host enzyme and improvements in nutrient utilization and animal performance in both weaned and fattening pigs.
Key words: Piglet, fattening pigs, multienzyme, digestibility, growth, feed efficiency, net profit, economic benefit return
