慢性应激对AA肉鸡生产性能和肉质的影响
Effects of Chronic Stress on Production Performance and Meat Quality of Broliors
摘要
Abstract
The purpose of this study was to test the effects of three chronic stress factors on broilers production performance and meat quality. The three chronic stress factors included social isolation group (SIG), high-density group (HDG) ,interference group(IG) and cage free group (control group) . The experimental results indicated that the stress factor had effects on broilers' body weight. Body weight of each group were not significantly different in 6 week age. And the body weight from IG and cage free group were significantly higher than that of SIG and HDG in 7 week age;the body weight from IG and cage free group were significantly higher than that of HDG in 8 week age, and the body weight from cage free group were significantly higher than other three groups in 9 week age and IG were significantly higher than HDG at the same time. Stress factors had no effects on broilers shank girth, but had some effects on broilers shank length. The shank length were not significantly different between each group in 6,7 and 8 week age, but the shank length from cage free group is significantly higher than other groups. Stress factors had some effects on broilers meat quality. The pH value,shear force,crude protein and meat color were not significantly different between each group; but the drip loss from SIG was significantly higher than that of other groups; and the crude protein from cage free group were significantly lower than that of other groups.关键词
