The aim of study was to investigate the effect of genotype on carcass measurements and meat quality characteristics of purebred Hair Goat, Saanen x Hair Goat (F(1) and B(1)) kids under an intensive production system. In total, 24 kids were slaughtered at the age of approximately 133 days. Kids were fattened for 56 days immediately after weaning. Hot carcass weights were 6.78, 7.61 and 7.02 kg and dressing percentages were 49.71, 49.27 and 48.78%, respectively (P > 0.05). Differences between genotypes for carcass measurements and indexes were not significant. Effect of genotype on pH measurements, drip loss, water holding capacity, cooking loss and Warner Bratzler shear force values were not significant. Meat lightness values at 0 h, 1 h and 1 day after cutting were higher in crossbred kids than Hair Goat kids (P < 0.05). Redness value was significantly higher in meat samples of Hair goat kids at 0 h, 1 h and 1 day measurements (P < 0.05). Kid genotype had no significant effect on meat sensory characteristics, except tenderness. Panelists gave lower scores for meat tenderness to F(1) and B(1) crosses compared to purebred Hair Goat kids. In conclusion, higher meat lightness values of crossbred kids, at particularly B(1) level, might have a positive effect on the consumer choices.
本研究旨在探讨基因型对集约化生产体系下纯种努比亚山羊和努比亚山羊与萨能奶山羊杂交(F(1)和 B(1))羔羊胴体测量和肉质特性的影响。总共 24 只羔羊在大约 133 日龄时屠宰。羔羊断奶后立即育肥 56 天。热胴体重分别为 6.78、7.61 和 7.02kg,屠宰率分别为 49.71%、49.27%和 48.78%(P>0.05)。不同基因型间胴体测量和指数无显著差异。基因型对 pH 值、滴水损失、水分保持能力、蒸煮损失和 Warner-Bratzler 剪切力值无显著影响。宰后 0h、1h 和 1d 时,杂种羔羊的肉色值高于努比亚羔羊(P<0.05)。宰后 0h、1h 和 1d 时,努比亚羔羊的肉红色值显著高于努比亚羔羊(P<0.05)。除嫩度外,羔羊基因型对肉的感官特性无显著影响。品尝者对 F(1)和 B(1)杂交羔羊的嫩度评分低于纯种努比亚羔羊。总之,杂种羔羊较高的肉色值,特别是 B(1)水平,可能对消费者的选择有积极影响。
