Effect of Probiotic and Toxin Binder on Performance, Intestinal Microbiota and Gut Morphology in Broiler Chickens
Journal Title: Journal of Animal Science Advances - Year 2015, Vol 5, Issue 7
Abstract
The effects of an antibiotic growth promoter (oxytetracycline), a probiotic, a mycotoxin binder, and a mixture of the probiotic and mycotoxin binder on growth performance, intestinal microbiota and gut morphology were examined in two hundred and forty 1-d-old Arbor Acre broiler chicks. They were randomly assigned to 5 dietary treatments with 6 replicate groups of 8 birds each. A corn-soyabean-based diet was formulated to serve as the basal diet (negative control, NC) at both starter and grower phases. The basal diet+antibiotic was the positive control (PC). The other test diets were basal diet+1.0% probiotics (PB), basal diet+0.05% mycotoxin binder (MB), and basal diet+1.0% PB and 0.05% MB. Body weight gain (BWG), feed and dry matter intake were significantly (P<0.05) improved in birds fed the PB and MB diets over the NC diet but not up to the PC diet at starter phase only. The Feed Conversion Ratio (FCR) was not influenced by dietary treatments at both starter and grower phases but gain: feed (G: F) was significantly (P<0.05) influenced by dietary treatments at 0 to 35 d, with improved G: F observed in birds fed NC+MB and NC+PB+MB diets. Weight of pancreas was remarkably (P<0.05) higher in birds fed diets supplemented with MB, PB and PB+MB over the controls. The villus height of birds fed NC+PB was significantly (P<0.05) improved than other dietary treatments, while the crypt depth of birds fed NC+PB and NC+MB was significantly (P<0.05) improved over the controls and NC+PB+MB diets. Microflora count in the gut sections showed significant (P<0.05) increase in coliform load in the duodenum, ileum and caecum in birds fed NC diet. However, in the ileum, there was a significant (P<0.05) increase in LAB in birds on NC+PB diet.
