The aim of this study was to compare the growth performance parameters, carcass quality, and meat traits in broiler chickens fed on diets containing legume seeds and rapeseed meal as an alternative to soybean meal. In this study, 448 male ROSS 308 chicks were divided into subgroups: a control group (I) fed on soybean meal (SBM), and six experimental groups II-rapeseed meal (RSM); III-white lupin (WY); IV-yellow lupin (YL); V-narrow-leaved lupin NLL; VI-pea (Pe); and VII-faba bean (FB). After 42 days of rearing, 10 birds from each group were slaughtered and dissected. The control group was characterized by better growth performance compared to the other groups. In addition, the European Broiler Index was lower in each experimental group compared to the SBM group. A lower dressing percentage was found only in the NLL group. The muscle content in birds from the RSM and FB groups was significantly higher than in the other groups, but the fat content was lower. Meat from SBM group was characterized by the highest protein content, but a reduced content of fat and water in the muscles. The most similar results were found between the control group and the FB group receiving a diet based on faba beans. Furthermore, lupins had a similar effect on the carcass traits when used in the diets. The quality of meat in broilers fed on faba beans with the addition of potato protein and brewers' yeast was similar to that of those fed on soybean meal, because the antinutrients were the lowest in faba bean seeds. Faba beans are proposed as a possible alternative source of protein in poultry diets. Other legume seeds should be analyzed in future studies.
本研究的目的是比较以豆类种子和菜籽粕替代豆粕的日粮喂养的肉鸡的生长性能参数、胴体品质和肉质特性。在本研究中，448只雄性ROSS 308雏鸡被分为亚组：对照组（I）饲喂豆粕（SBM），六个实验组：II - 菜籽粕（RSM）；III - 白羽扇豆（WY）；IV - 黄羽扇豆（YL）；V - 窄叶羽扇豆（NLL）；VI - 豌豆（Pe）；VII - 蚕豆（FB）。饲养42天后，每组宰杀10只鸡并进行解剖。与其他组相比，对照组的生长性能更好。此外，每个实验组的欧洲肉鸡指数均低于SBM组。仅在NLL组发现屠宰率较低。RSM组和FB组鸡的肌肉含量显著高于其他组，但脂肪含量较低。SBM组鸡肉的蛋白质含量最高，但肌肉中的脂肪和水分含量降低。对照组和接受以蚕豆为基础日粮的FB组之间的结果最为相似。此外，羽扇豆在日粮中使用时对胴体性状有类似影响。添加马铃薯蛋白和啤酒酵母的蚕豆喂养的肉鸡的肉质与豆粕喂养的肉鸡相似，因为蚕豆种子中的抗营养物质含量最低。蚕豆被提议作为家禽日粮中一种可能的蛋白质替代来源。其他豆类种子应在未来研究中进行分析。
