Abstract
In orderto study slow -release coated cysteam ine on growth perform ance ofgrow ing-finishing pigs and carcass quality,select"Du Chang Da" 120 crossbred pigs were random ly divided into three groups com parison test,exam ine its perform ance, blood physicochem ical slaughter perform ance indicators and targets. The results show that: the experim entalgroup grow ing season,fulloffattening period and average daily gain were increased by 7.34% ,5.09% and 6.32% ;feed conversion ratio were decreased by 4.93% ,3.19% and 4.40% ;average daily feed intake were im proved 2.20% ,1.61% and 1.90% ,butthe difference w as notsignificant.Hip and leg percentage ofthe testgroup,loin eye area and lean meatrate increased by 9.25% ,11.69% and 6.27% ;backfatthickness decreased 13.74% .Testgroup serum GH , T3 levels were increased by 18.68% ,20.63% ,while no significanteffecton the INS and T4.Itshow ed thatdiets after slow -release coated cysteam ine, may by increasing the level of serum GH , T3 and other horm ones, im prove growth perform ance and carcassquality ofgrow ing-finishing pigs.关键词
