Safety and efficacy evaluation of a novel dietary muramidase for swine.

The safety of a novel microbial muramidase (Muramidase 007) as a feed additive for swine was evaluated in a target animal safety study (Experiment 1). Forty weanling pigs were allotted to 4 dietary treatments: T1 control group, and 3 groups receiving Muramidase 007 in increasing doses: T2 65,000 (1X), T3 325,000 (5X) and T4 650,000 (10X) LSU(F)/kg feed. The efficacy of Muramidase 007 on growth performance was evaluated in a feeding experiment (Experiment 2).
