Evaluation of Lactobacillus Plantarum Additive on Growth Performance, Excreta Microbiota, Nutrient Digestibility, Gas Emission, and Meat Quality in Ross308-Broilers

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)

Supplemental Effect of Lactobacillus Plantarum on the Growth Performance, Nutrient Digestibility, Gas Emission, Excreta Microbiota, and Meat Quality in Broilers

The goal of this study was to investigate the effects of Lactobacillus plantarum (L. plantarum) supplementation on the growth performance, nutrient digestibility, gas emission, excreta microbiota, and meat quality in broilers. A total of two hundred eighty-eight, one-day-old Ross-308 chicks (mixed sex) were randomly allocated to one of two treatments with eight replicated cages (18 chicks per cage). For a period of 35 days, control treatment chicks were fed commercial corn-soybean meal-based (CON) mash form diet, whereas, LP (Lactobacillus plantarum) - chicks were fed CON with 0.10% L. plantarum supplement. The dietary inclusion of 0.10% L. Plantarum supplementation has a trend to increase the body weight gain (BWG) of broilers at day 7(p=0.079) and significantly increased at day 21 (p=0.011) and the overall trial period (p=0.037) compared to the CON diet. In addition, 0.10% L. plantarum supplementation to basal diet significantly decreased H2S (p=0.046) concentration. Also, it has significantly increased the excreta Lactobacillus population (p=0.041) and reduced the E. coli count (p=0.054) compared to the CON diet. However, throughout the trial there were no significant differences observed on nutrient digestibility of dry matter, nitrogen, and gross energy, as well as meat quality traits in broilers, fed 0.10% L. plantarum diet. In summary, the inclusion of L. plantarum supplementation has a beneficial effect on growth performance, excreta microbiota, and gas emission. From this, we conclude that 0.10% of L. plantarum could be a potential feed additive to enhance poultry production.(AU)
