Abstract

A study was conducted to determine the effect of probiotics Lactobacillus acidophilus (Lactic acid bacteria) on performance of broilers chickens. One hundred and twenty (120), one-day old broiler chicks of Abor Acre Plus strain were divided equally into 4 groups with 3 replicates of 10 birds each. Chickens were housed in double open-sided pens measuring 1.0—1.2 m for 42 days. Feed and water were provided ad-libitum. There were four dietary treatments. Dietary treatments were T1-1.45×109 CFU probiotic/kg basal feed, T2-1.09×109 CFU probiotic/kg basal feed, T3-7.25—108 CFU probiotic/kg basal feed and T4-No probiotics supplementation (control). Feed intake and weight gain were recorded weekly. Total body weight gain was significantly higher (P<0.05) in T1 (1621.44±53.91 g) when compared to T2, T3 and T4; 1407.67±10.23 g, 1258.87±21.49g and 1261.38±63.54 g respectively. Feed consumption was higher in T3 (4131.10±264.59g) but differences were not-significant (P>0.05). Serum cholesterol level was significantly (P<0.05) lower in T1 (3.29±0.26 Mmol/dl) and highest in T4-control (4.34±0.24Mmol/dl). Consequently, dietary supplementation of probiotic in broiler chicken feed at 1.45×109 CFU/kg for 42 days enhanced weight gain with better feed conversion ratio and reduced serum cholesterol.
