A microbial muramidase improves growth performance and reduces inflammatory cell infiltration in the intestine of broilers chickens under Eimeria and Clostridium perfringens challenge.

The objective of the present studies was to evaluate muramidase (MUR) supplementation in broilers under Eimeria and/or Clostridium perfringens challenge. For this, 2 experiments were conducted. Experiment 1.

Efficacy and safety profile of a subtilisin protease produced by fermentation in to be used as a feed additive.

The efficacy and safety of a novel Subtilisin protease from a produced in was investigated in broiler chickens, and a range of toxicological tests, respectively. The production strain culture supernatant was not found cytotoxic in a Vero cell assay. Subtilisin was non-mutagenic and non-clastogenic in tests, and did not exhibit irritating potential to the eye or skin in / models.

Quantifying the effect of coccidiosis on broiler performance and infection outcomes in the presence and absence of control methods.

A systematic review and meta-analysis was conducted to investigate the role of Eimeria species, dose and inoculation time, on performance and infection outcomes of different broiler strains infected for different study durations. The meta-analysis addressed E. acervulina, E.
