Effect of clonidine on carcass composition of growing pigs and approach to the mechanism of the effect
Sixty growing pigs (Daroc (Landrace (Yorkshine) were used to study the effect of clonidine on carcass composition and its mechanism. The results showed that supplementation of 0.5 mg/kg clonidine to feed increased lean meat percentage and eye muscle area of pigs by 5.29%(P<0.01) and 8.41%(P&a...

| Summary: | Sixty growing pigs (Daroc (Landrace (Yorkshine) were used to study the effect of clonidine on carcass composition and its mechanism. The results showed that supplementation of 0.5 mg/kg clonidine to feed increased lean meat percentage and eye muscle area of pigs by 5.29%(P<0.01) and 8.41%(P<0.01), weight of the longissimus dorsi, biceps femoris and quadriceps femoris by 13.77% (P<0.01), 11.11%(P<0.05) and 8.93%(P<0.05), and decreased fat percentage and back fat thickness by 9.53%(P<0.01) and 10.34%(P<0.05), respectively. In serum, GH and IGF-1 level were raised (P <0.05), urine nitrogen and triglyceride concentration decreased (P<0.05), and free fatty acids increased (P<0.05). In subcutaneous fat tissues, the malic dehydrogenase and glucose-6-phosphate dehydrogenase activities were lowered (P<0.01), and the hormone sensitive lipase activities improved (P<0.05). |
