Abstract
The probiotic effects of Lactobacillus rhamnosus strain CF (Chen Fu) on growth performance, meat quality, and microenvironment in specific pathogen-free (SPF) chickens were investigated and compared with Enterococcus faecium. One-hundred-eighty 7-day-old SPF chickens were randomly assigned into 3 groups with 3 replicate pens of 20 chickens each. Group 1 served as a control that was fed a basal diet without probiotics supplementation. Groups 2 and 3 were fed the basal diet supplemented with L. rhamnosus CF and E. faecium, respectively. On d 12 and 24, BW, ADG, feed conversion ratio (FCR), dressing percentage (DP), and apparent digestibility of crude protein (AD-CP) were calculated. Meat color, fat content, shear force, water content, and pH value of breast and thigh muscles; ammonia, urea nitrogen, and uric acid content in plasma; pH value, Enterococcus, Lactobacillus, and E. coli in ceca; and ammonia emission were determined. Compared with group 1, group 2 exhibited higher BW, ADG, AD-CP, DP, cecal Lactobacilli, and muscle fat content (P < 0.05) as well as lower FCR, muscle water content, plasma ammonia, pH value, E. coli, and Enterococcus in ceca, and ammonia emission (P < 0.05), and group 3 exhibited higher BW, ADG, AD-CP, DP, and muscle fat content (P < 0.05), as well as lower FCR, meat color, plasma ammonia, E. coli and Enterococcus in ceca, and ammonia emission (d 24) (P < 0.05). Compared with group 3, group 2 exhibited lower plasma ammonia level, E. coli, and pH value in ceca and ammonia emission (P < 0.05) and higher AD-CP, meat color, pH value in thigh muscles, fat content in breast muscles, and number of Lactobacillus in ceca (P < 0.05). Thus, L. rhamnosus CF improves growth performance, meat quality, and microenvironment and is a potential probiotic additive in chickens.
