The present study investigated the effect of flaxseed grain or flaxseed oil on ileal microbiota and lipid deposition of cashmere goats. Sixty kid goats (average body weight 18.6 ± 0.1 kg) were allocated to three treatments, fed for 90 days, with control treatment: basal diet (CON, total-mixed ration), experimental treatment: basal diet with added flaxseed oil (LNO), experimental treatment: basal diet with added heated flaxseed grain (HLS). The final body weight, body weight gain, the weight of kidney fat, omental fat, tail fat, and fat tissue, the activity of fatty acid synthetase, acetyl-coa carboxylase, and malic dehydrogenase, and the relative abundance (RA) of and were remarkably higher in the LNO treatment than in the HLS treatment, but the RA showed the opposite result. The content of triglyceride, cholesterol, and low-density lipoprotein cholesterol were significantly higher in the CON and LNO treatments than in the HLS treatment, while the hormone-sensitive lipase activity and the non-esterified fatty acid content showed the opposite result. In conclusion, the flaxseed grain is more efficient than flaxseed oil in ameliorating the blood lipid profiles and it is a potential product for decreasing the lipid deposition of cashmere goats.
本研究调查了亚麻籽或亚麻籽油对绒山羊回肠微生物群和脂质沉积的影响。将60只小山羊（平均体重18.6±0.1千克）分配到三种处理组，饲喂90天，对照处理：基础日粮（CON，全混合日粮），试验处理：基础日粮添加亚麻籽油（LNO），试验处理：基础日粮添加加热的亚麻籽（HLS）。LNO处理组的最终体重、体重增加量、肾脂肪、网膜脂肪、尾脂和脂肪组织重量、脂肪酸合成酶、乙酰辅酶A羧化酶和苹果酸脱氢酶的活性以及 和 的相对丰度（RA）均显著高于HLS处理组，但 RA结果相反。CON和LNO处理组的甘油三酯、胆固醇和低密度脂蛋白胆固醇含量显著高于HLS处理组，而激素敏感性脂肪酶活性和非酯化脂肪酸含量结果相反。总之，亚麻籽在改善血脂方面比亚麻籽油更有效，是减少绒山羊脂质沉积的潜在产品。
