20 American strain Rex rabbits were slaughtered to study the characteristics and correlations of carcass and meat quality. The results showed: the average weight,commercial skin weight,dressing percentage,right hind leg weight,length and circumference length were 2.533 kg,0.410 kg,60.70%,0.182 kg,30.69 cm and 18.04 cm respectively about 150 days.
The results show as follows: Compared with contrasts, white yak’s meat quality is better. It has the characteristics with higher protein(21.87g/100g, P<0.05), lower fat(1.79 g/100g,P<0.05) and abundant mineral materials,especially iron (6.60 mg/100g,P<0.01).
Bystudies on growth development,slaughter traits and muscle quality in Taihe silkies and local yellow chickens,the results show:Body weight in Taihe silkies are lower significantly than that in Local yellow chickens on different stage,slaughter rate in Taihe silkies are also lower singnifcantly than that of Local yellow chickens,but muscle quality(meat colour,tendness degree) are better obviously than Local yellow chickens.
The experiment was conducted to evaluate the effects of chromium picolinate (CrP) on growth performance, pork quality of swine. Moreover, the experiment applied molecular means, mainly RT-PCR (reverse transcription-polymerase chain reaction), to exploit the molecular mechanism of CrP.
The experiment was conducted to evaluate the effect of dbcAMP on regulating the carcass composition and meat feature in pigs by subcutaneous injecting and basic diets supplementing dbcAMP with different dosages.
