Twenty-four entire male Kacang kid goats were fed diets containing 3% canola (n=12) or palm oil (n=12) supplements for 16 weeks. The goats had an initial live weight of 14.2±1.46 kg and were fed a mixed ration ad libitum (10.4 MJ/ME and 14% crude protein). There was no difference in feedlot performance due to diet. Inclusion of canola oil reduced (P<0.05) kidney fat weight and increased (P<0.05) linolenic acid (18:3n-3) concentration in the blood plasma, m. longissimus lumborum (LL), liver, and kidney. The palm oil diet increased (P<0.05) myristic (14:0) and palmitic (16:0) acid content in the blood, but this did not alter these fatty acids in the LL muscle. Lipid oxidative substances in the liver and LL from palm oil fed kids were higher (P<0.05) than those from canola supplemented kids. The incorporation of canola oil into the goats' diet increased muscle omega-3 fatty acid content, but lipid oxidation was lowered in the blood and muscle LL.
24 只雄性卡苍山羊接受了为期 16 周的含有 3%菜籽油（n=12）或棕榈油（n=12）补充剂的饮食。这些山羊的初始活重为 14.2±1.46 公斤，自由采食混合日粮（10.4 MJ/ME 和 14%粗蛋白）。由于饮食的不同，肥育性能没有差异。添加菜籽油可降低（P<0.05）肾脏脂肪重量，并增加（P<0.05）血浆、背最长肌（LL）、肝脏和肾脏中的亚麻酸（18:3n-3）浓度。棕榈油饮食增加（P<0.05）血液中肉豆蔻酸（14:0）和棕榈酸（16:0）的含量，但这并没有改变 LL 肌肉中的这些脂肪酸。棕榈油喂养的羔羊肝脏和 LL 中的脂质氧化物质（P<0.05）高于菜籽油补充剂喂养的羔羊。在山羊饮食中添加菜籽油会增加肌肉 ω-3 脂肪酸的含量，但会降低血液和肌肉 LL 中的脂质氧化。
