Abstract
The effects of six Lactobacillus strains transformed with a heterologous beta-glucanase gene on the growth performance of broiler chickens were determined in the present study. Chickens fed with a basal diet supplemented with transformed Lactobacillus strains were found to have significantly improved P0.05 body weight body weight gain and feed conversion ratio. Supplementation of transformed Lactobacillus strains to the diet also significantly P0.05 increased the intestinal beta-glucanase activity and reduced the viscosity of intestinal fluid. The apparent metabolisable energy digestibilites of crude protein and dry matter of feed in these chickens were significantly improved by 3.5 0.056 and 3.5 respectively. In addition the feed passage rate of chickens fed transformed Lactobacillus strains was reduced by 2.2 h when compared to chickens fed the other dietary treatments.
