摘　　要：选用 2 0 kg左右的“杜长”元杂交猪 2 4头 ,随机分成 1个对照组、 3个试验组 ,试验组分别添加环腺苷酸制剂 (二丁酰 c AMP) 10 mg/kg(试验 1组 )、 2 0 mg/kg(试验 2组 )、 30 mg/kg(试验 3组 ) ,进行饲养试验、屠宰试验和肉的品质测定。结果表明 :添加二丁酰 c AMP,能提高生长育肥猪的生长性能和改善肉脂品质。以添加二丁酰 c AMP2 0 mg/kg效果最好 ,与对照组相比 ,日增重提高 11.80 % (P <0 .0 1) ,料重比降低 16 .4 % (P <0 .0 1) ,胴体瘦肉率提高 8.12 % (P <0 .0 5 ) ,眼肌面积增加 11.98% (P <0 .0 5 ) ,平均背膘厚下降 18.90 % (P <0 .0 1) ;大理石纹评分提高 11.6 6 % (P <0 .0 1) ;肌肉间脂肪含量提高 2 8.88% (P <0 .0 1)。growing and finishing pigs(Duroc×Landrace 20 kg initially)were assigned into one control group and three test groups Fed basic diet supplemented with dbcAMP10、20、30 mg/kg for test group 1,test group 2,and test group 3 respectively The results showed that dbcAMP can improve the growing performance,the carcass characteristics and meat features of growing and finishing pigs It shows that supplement with dbcAMP 20 mg/kg,comparing to the control group,ADG increasing about 11 80%(P<0 01) and and FCR decreasing about 16 4%(P<0 01);the lean meat percentage increasing about 8 12%(P<0 05) and the rib eye areas increasing about 11 98% (P<0 05),the mean backfat depth decreasing about 18 90% (P<0 01) It also shows that the marbling grade of musclar increases 11 66%(P<0 01),and the content of intramusclar fat increases 28 88%(P<0 01)
