Pengaruh Suplementasi Probiotik Bakteri Asam Laktat Terhadap Histomorfologi Usus Dan Performan Puyuh Jantan

Abstract

The present study was conducted to investigate the effects of lactic acid bacteria (LAB ) probiotic s supplementation on intestinal histomorpholgy and performance of male quail. The LAB probiotics supplement contained of three strains, those are Lactobacillus murinus, Streptococcus thermophilus, and Pediococcus acidilactici. A total of 96 day-old male quails (DOQ) were randomly divided into four groups of LAB probiotic supplementation r eared for 42 days . O ral supplementation of LAB probiotic were 0 (P0) , 10 7 (P1) , 10 8 (P2) , and 10 9 (P3) CFU/mL/bird/day. Data were analyzed by analysis of variance CRD One-Way Anova continued with Duncan’s New Multiple Range Test (DMRT) . The results showed that LAB probiotic treatment a ffect ed on the intestinal morphology, body weight gain , and feed conversion of male quail (P <0.05). Height of intestinal villi were 288.45±8.18 , 322.72±1.84 , 324.82±2.06 , and 390.80±13.24 (µm) respectively. Width of intestinal villi were 112.82±2.35 , 138.62±2.35 , 162.57±17.15 and 130.72±13.45 (µm) respectively. Depth of intestinal crypts were 61.25±1.49 , 72.50±6.25 , 69.85±4.55 , and 69.05±4.57 (µm) respectively . Feed intake were not different, but resulted difference body weight gain, which wer e 102.85±4.72 , 109.20±4.13 , 115.07±7.61 , and 118.75±2.54 ( g ), respectively . Feed conversion were 4.30±0.43 , 4.26±0.17 , 3.91±0.30 , and 3.79±0.27 , respectively. This study indicated that supplementation of 10 9 CFU / m L / bird /day of LAB probiotic s showed the best result.
