摘要:

将18 头60kg 左右的杜长大三元杂交猪随机分为两个处理组,分别饲喂高、低能量水平两种日粮,研究不同能量水平对H-FABP 基因表达量及肉质性状的影响。结果表明:高能量水平有促进H-FABP 基因表达的趋势(P > 0.05),高能量水平显著提高了背膘厚(BFT)和肌内脂肪(IMF)含量(P < 0.05)。猪H-FABP 基因表达量与IMF 含量呈显著正相关(P < 0.05);IMF 含量与BFT 呈显著正相关(P < 0.05)。这表明能量水平对H-FABP 基因表达量有一定的影响,可以影响肉质。

Abstract:

In order to explore the effect of energy level on H-FABP gene expression and pork quality, 18 DLY pigs (60 kg) were randomly divided into two groups, which were fed food containing high energy (DE 13.85 MJ/kg, CP 14%) and low energy (DE 12.75 MJ/kg, CP 14%), respectively. All the pigs were slaughtered at the body weight of 100 kg to determine H-FABP gene expression and meat quality traits. The results showed that high-energy food increased H-FABP gene expression (P>0.05). Highenergy food also increased intramuscular fat (IMF) content and back fat thickness (BFT) (P<0.05); H-FABP gene expression was positively correlated with IMF (P < 0.05) and IMF was positively correlated with BF (P < 0.05). These investigations suggested that energy level was able to affect FABP gene expression and meat quality.

Key words: pigs, energy level, H-FABP gene, gene expression, meat quality
