Abstract
A study was conducted to investigate the correlation of cecal anaerobic bacterial counts with the cecal length in growing chicks. Half of 160 chicks of five weeks old were housed in cages and the remainings were kept with goats in free-range and allowed to have free access to goat's feed and faeces. All the experimental birds were fed ad libitum on a commercial chick formula diet during the period of 5 to 12 weeks of age. Body weight was larger in birds reared in the cage than in those reared on the field at 8 weeks of age (P<0.05), but vice versa at the end of experiment (P<0.05). The cecal length was longer in field-rearing than in cage-rearing at 6, 9, 10 and 11 weeks of age (P<0.05). The cecal length was correlated with body weight gain in both rearing groups (r=0.816 f3r cage-rearing, r=0.816 for field-rearing). The cecal anaerobic bacterial counts were significantly higher in field- rearing than in cage-rearing at 6, 9, 10 and 11 weeks of age (P<0.05). The cecal length was highly correlated with cecal anaerobic bacterial counts in cage- (r=0.9549) and field-(r=0.9866) rearing. It is concluded that the correlation of increase cecal length with increased cecal anaerobic bacterial counts ted a libelous of goat's faeces in growing chicks.
