Evaluation of Apparent Metabolic Energy and Comparison of Nutrient Digesibility of Different Sources Sorghum by Feeding Yellow?Feathered Broilers
摘要
Abstract
This study was conducted to evaluate the apparent metabolizable energy ( AME ) and compare the difference of nutrient digesibility of different sources sorghum by feeding yellow?feathered broilers. Twenty four 56?day?old healthy male yellow?feathered broilers were randomly allocated to four groups with six replicates per group and one broiler per replicate according single?factor randomized design. The experimental diets were the American sorghum, Hunan sorghum and Inner Mongolia sorghum to replace 20% corn in the basal diet, re?spectively, and evaluated the AME and compared the difference of nutrient digesibility of American sorghum, Hunan sorghum and Inner Mongolia sorghum. The experimental period lasted for 7 days, including 2 periods of 4?day pre?test period and 3?day test period. The results showed as follows:1) the AME of Inner Mongolia sorghum was the highest, which was significantly higher than that of American sorghum and Hunan sorghum for 12.17% and 15.81% ( P<0.01) . 2) The apparent digesibility of crude fiber ( CF) of Inner Mongolia sor?ghum was the highest, which was significantly higher than that of American sorghum and Hunan sorghum for 23.81% and 27.87% (P<0.01); closely followed by the apparent digesibility of CF of American sorghum, which was significantly higher than that of Hunan sorghum for 3.28% ( P<0.01) . The apparent digesibility of ether extract ( EE) of Inner Mongolia sorghum was significantly lower than that of Hunan sorghum for 0.05%( P<0.01) . There were no significant difference in the apparent digesibility of crude protein ( CF) , dry matter (DM), crude ash (Ash) and nitrogen?free (NFE) of different sources sorghum (P>0.05). In conclusion, the AME of American sorghum, Hunan sorghum and Inner Mongolia sorghum by substitution method are 13.39, 12.97 and 15.02 MJ/kg, respectively. The AME and the apparent digesibility of EE and CF of differ?ent sources sorghum have significant differences, and the apparent digesibility of the other nutrients have no significant differences.关键词
