The influence of dietary inclusion of Plukenetia conophora seed (PCS) on growth, carcass, muscle antioxidant enzymes, fatty acids, meat quality, and sensory attributes of Longissimus thoracis et lumburum muscle in rabbits was examined. Seventy-two, 28 d old male New Zealand rabbits (750 ± 20 g) were randomly allotted to diets containing either no PCS (PCS-0), 2.5% PCS (PCS-2.5) or 5% PCS (PCS-5) for eight weeks, and euthanized. PCS-5 rabbits had higher (P < 0.05) body and carcass weights than the PCS-0 rabbits. Dietary PCS improved feed efficiency in rabbits. Muscle antioxidant enzymes activities and total phenols were higher while muscle cholesterol was lower (P < 0.05) in supplemented meat than the PCS-0 meat. The concentration of C22:6n-3, C20:5n-3 and C18:3n-3 was higher (P < 0.05) in the supplemented meat than the PCS-0 meat. Sensory attributes, carbonyl, and TBARS values and physicochemical properties of meat did not differ among diets. Supplementation of PCS-5 enhances muscle n-3 fatty acids without impairing the sensory properties, and oxidative stability of rabbit meat.
研究了日粮中添加南美油藤种子（PCS）对家兔生长性能、胴体品质、肌肉抗氧化酶、脂肪酸、肉质及背腰最长肌感官特性的影响。选用72只28日龄雄性新西兰家兔（体重750±20 g），随机分为3组，分别饲喂不含PCS的日粮（PCS-0）、含2.5% PCS的日粮（PCS-2.5）和含5% PCS的日粮（PCS-5），为期8周，之后实施安乐死。与PCS-0组家兔相比，PCS-5组家兔的体重和胴体重更高（P<0.05）。日粮中添加PCS可提高家兔的饲料效率。与PCS-0组肉相比，添加PCS组肉的肌肉抗氧化酶活性和总酚含量更高，而肌肉胆固醇含量更低（P<0.05）。与PCS-0组肉相比，添加PCS组肉中C22:6n-3、C20:5n-3和C18:3n-3的浓度更高（P<0.05）。不同日粮组肉的感官特性、羰基值、硫代巴比妥酸反应物（TBARS）值和理化性质无差异。添加5% PCS可提高兔肉的n-3脂肪酸含量，且不影响其感官特性和氧化稳定性。
