Resumo
The intention of this study was to analyze the effects of Lactobacillus plantarum (L. plantarum) additive with different nutrient density diets on growth performance, excreta microbiota, nutrient digestibility, gas emission, and meat quality in Ross308-broilers. A total of 576 mixed-sex, 1-d old Ross-308 chicks were randomly allocated to one of four treatment groups with 8 replication and 18 chicks/cage. For a period of 35 days, HD and LD group chicks were fed with commercial corn and soybean meal-based basal diet which contains high and low nutrient density diet, respectively. The other treatment groups LP1 and LP2 chicks were fed with LD+ 0.05% and 0.01 % of L. plantarum, respectively. During day 21 and the overall experimental period, the body weight gain of broilers significantly increased (p<0.05) in HD and L. plantarum groups compared to the LD group. On day 35, broilers fed L. plantarum additive had significantly increased (p<0. 05) the nutrient digestibility of dry matter and nitrogen compared to those fed HD and LD diets. Moreover, dietary inclusion of L. plantarum additive had significantly increased (p<0.05) lactobacillus population and decreased (p>0.05) E. coli and ammonium emission. However, the meat quality traits were not affected by experimental diets. In conclusion, we infer that a low-density diet with 0.1% of L. plantarum additive could serve as an excellent alternative feed additive to enhance the performance of broilers.(AU)
