摘要： Protein sources in livestock feed include cottonseed meals (CSM) or rapeseed meals (RSM). However, their use in feed diets is restricted due to anti-nutritional elements such as free gossypol or glucosinolate. The main objective of this study was to determine the effect of microbial fermentation of total mixed ration (TMR) with CSM/RSM on the growth performance and meat quality of Hu lamb. Fifty-one male Hu lambs (4 months old) with a 22.51 kg body weight were randomly assigned to three treatments and fed unfermented TMR with soybean meal (control group), FTMR (fermented total mixed ration) with CSM or RSM, respectively. The experiment lasted 97 days. Growth performance, rumen fermentation, and meat quality were measured. Overall dry matter intake (DMI), average daily gain (ADG), and final body weight (FBW) were similar among treatments (p > 0.05). There were no significant differences in the lightness (L*), redness (a*), and yellowness (b*) of longissimus thoracis (LT) muscle meat. There were no significant differences between the FTMR-CSM/RSM and control groups in drip loss, cooking loss, cooking percentage rate, or shear force of LT muscle meat. Lambs fed FTMR-CSM had significantly higher rumen fluid total volatile fatty acid values than those in control or FTMR-RSM groups (p < 0.05). Meat from lambs fed FTMR-RSM had a higher level of saturated fatty acids than lambs fed the control diet. The LT muscle meat of lamb fed FTMR-CSM had more unsaturated fatty acids than the control group (p < 0.001). In conclusion, FTMR with cottonseed or rapeseed meal can be fed without causing any adverse effects on Hu lamb.
