The influence of dietary Tetracarpidium conophorum (African Walnut) seed meal (TCSM) on fatty acids, productivity parameters, and physicochemical properties of breast and thigh muscles in broiler chickens are assessed. A total of 180, 28‐d‐old Arbor acre broiler chickens are randomly assigned to dietary treatments containing 0% (control), 2.5%, and 5% w/w TCSM, fed for 28 d, and euthanized. Dietary TCSM reduces (p < 0.05) feed intake, body weight gain (BWG), carcass weight, and abdominal fat. Diet does not affect feed efficiency and hematological parameters. The control birds have higher (p < 0.05) serum total cholesterol and triglycerides than do the supplemented birds. Diet has no effect on pH, water holding capacity, carbonyl and malondialdehyde contents, and organoleptic properties of breast and thigh muscles. The 5% TCSM has higher redness in breast muscle than do other treatments. Dietary TCSM improves (p < 0.05) the concentration of C18:3n‐3 (4.80–8.76% vs 1.56%), C20:5n‐3 (0.54–0.79% vs 0.39%), C22:5n‐3 (0.64–0.89% vs 0.18%), and C22:6n‐3 (0.75–0.97% vs 0.19%), and reduces (p < 0.05) the fat content (2.15–2.45% vs 3.15%) in breast and thigh muscles. Dietary TCSM enhances muscle n‐3 fatty acids without instigating oxidative deterioration, but reduces BWG in broiler chickens.

饮食补充四叶草(非洲核桃仁)种子可提高肉鸡的肌肉n-3脂肪酸

评估了日粮四叶草(非洲核桃仁)种子粉(TCSM)对肉鸡中脂肪酸,生产力参数以及乳房和大腿肌肉的理化特性的影响。将总共​​180只28日龄的Arbor英亩肉鸡随机分配到含0%(对照),2.5%和5%w / w TCSM的饮食处理中,饲喂28天并实施安乐死。饮食TCSM减少(p  <0.05)采食量,体重增加(BWG),car体重量和腹部脂肪。饮食不影响饲料效率和血液学参数。对照鸟具有更高的(p <0.05)血清总胆固醇和甘油三酯比补充鸟类高。饮食对pH,保水性,羰基和丙二醛含量以及乳房和大腿肌肉的感官特性没有影响。5%TCSM的胸部肌肉发红率高于其他治疗方法。膳食TCSM可提高(p  <0.05)C18:3n-3(4.80-8.76%vs 1.56%),C20:5n-3(0.54-0.79%vs 0.39%),C22:5n-3(0.64-0.89)的浓度(p <0.05) %vs. 0.18%)和C22:6n-3(0.75–0.97%vs.0.19%),并降低(p  <0.05)乳房和大腿肌肉的脂肪含量(2.15-2.45%vs 3.15%)。日粮TCSM可以增强肌肉n-3脂肪酸而不会引起氧化变质,但可降低肉鸡的BWG。
