摘要
This research investigated the effects of cassava residue meal (CRM) and fermented CRM (FCRM) on the growth performance, serum lipid indicators, carcass traits, and meat quality of Huanjiang mini-pigs. One hundred twenty Huanjiang mini-pigs with similar BW (body weight, 8.85 ± 0.64 kg) were divided into three dietary treatment groups: the CON group with a basal diet; the CRM group with a diet containing 5% CRM; and the FCRM group with a diet containing 5% FCRM. The feeding trial was conducted for 30 days. The findings revealed that dietary CRM and FCRM did not influence the growth performance and diarrhea rate of Huanjiang mini-pigs (p > 0.05). Dietary FCRM supplementation increased serum total cholesterol level compared to the CON group while decreasing serum cholinesterase level compared to the CON and CRM groups (p < 0.05). The level of serum low-density lipoprotein-cholesterol was higher (p < 0.05) in the CRM and FCRM groups in regard to the CON group. In addition, CRM and FCRM supplementation reduced (p < 0.05) the backfat thickness and carcass yield of Huanjiang mini-pigs. The meat quality analysis showed that dietary CRM and FCRM improved the meat quality by increasing the intramuscular fat content and redness (a*) value and decreasing the lightness (L*) value. Moreover, the MyHC-IIx expression in the longissimus thoracis (LT) muscle was upregulated (p < 0.05) in the CRM group, while MYHC-IIb expression displayed an increasing trend (p = 0.076) in the FCRM group relative to the CON group. The fatty acid composition in the LT muscle also revealed that the C20:0 level was lower in the CRM and FCRM groups, while the ∑SFA and ∑SFA/∑UFA were reduced (p < 0.05) in the FCRM group relative to the CON group. In summary, dietary CRM and FCRM supplementation improved the meat quality of Huanjiang mini-pigs without affecting growth performance and diarrhea rate. Notably, FCRM exhibited better effects on meat quality than CRM.

这项研究调查了木薯残留粉（CRM）和发酵CRM（FCRM）对Huanjiang Mini-Pigs的生长性能，血清脂质指标，car体性状和肉质的影响。一百二十二十个huanjiang迷你猪具有相似的BW（体重，8.85±0.64 kg）分为三个饮食治疗组：基础饮食的骗局；CRM组，含有5％CRM的饮食；和含有5％FCRM的饮食的FCRM组。进食试验进行了30天。研究结果表明，饮食中的CRM和FCRM不会影响Huanjiang Mini-Pigs的生长性能和腹泻率（P> 0.05）。与CON组相比，与CON和CON组相比，与CON组相比，饮食中的FCRM补充剂增加了血清总胆固醇水平，同时降低了血清胆碱酯酶水平（P <0.05）。与CON组相对于CRM和FCRM组，血清低密度脂蛋白 - 胆固醇的水平较高（P <0.05）。此外，CRM和FCRM补充减少（p <0.05）Huanjiang Mini-Pigs的反脂肪厚度和car体产量。肉质质量分析表明，饮食中的CRM和FCRM通过增加肌内脂肪含量和发红（A*）价值并降低轻度（L*）值来改善肉质的质量。此外，在CRM组中，longissimus thoracis（LT）肌肉中的MyHC-IIX表达上调（p <0.05），而MyHC-IIB表达在相对于CON组的FCRM组中显示出越来越多的趋势（P = 0.076）。LT肌肉中的脂肪酸组成还表明，CRM和FCRM组的C20：0水平较低，而FCRM组的∑SFA和∑SFA和∑SFA/∑SFA/∑FA/∑SFA/∑UFA降低（p <0.05）。团体。总而言之，饮食中的CRM和FCRM补充剂提高了Huanjiang Mini-Pig的肉质，而不会影响生长性能和腹泻率。值得注意的是，FCRM对肉质质量的影响比CRM更好。
