The effect of four castrated goat genotypes and sunflower cake supplementation on goat meat quality was determined. Supplemented Boer (BOR) and Xhosa-Boer cross (XBC) goats had significantly higher (P<0.05) SLW and CDM than non-supplemented groups. The Xhosa lop-eared (XLE) and Nguni (NGN) goats had higher pH24 (P<0.05) than BOR and XBC goats. For each genotype, the sunflower cake supplemented and non-supplemented goats had similar a* values, except for the XLE goats. In the XLE goats, the a* values were lower in the sunflower cake supplemented goats. Sunflower cake supplemented BOR goats had higher Lvalues than their non-supplemented counterparts (P<0.05). The sunflower cake supplemented BOR and NGN goats also had higher b values as compared to their non-supplemented counterparts. In comparison with the Boer goat, the XLE and NGN goats had lower CDM, L* and WBF values but generally had higher CL and a* values. Sunflower cake supplementation improved meat quality attributes of the goats.
四种去势山羊基因型和向日葵饼补充料对羊肉品质的影响。补充博尔(BOR)和科萨-博尔杂交(XBC)山羊的 SLW 和 CDM 明显高于未补充组(P<0.05)。科萨垂耳(XLE)和恩古尼(NGN)山羊的 pH24 高于 BOR 和 XBC 山羊(P<0.05)。对于每种基因型,补充和未补充向日葵饼的山羊的 a值相似,除了 XLE 山羊。在 XLE 山羊中,补充向日葵饼的山羊的 a值较低。补充向日葵饼的 BOR 山羊的 L值高于未补充的(P<0.05)。补充向日葵饼的 BOR 和 NGN 山羊的 b值也高于未补充的。与博尔山羊相比,XLE 和 NGN 山羊的 CDM、L和 WBF 值较低,但通常具有较高的 CL 和 a值。向日葵饼补充料改善了山羊的肉质属性。
