Broiler diets mainly consist of cereals and protein-rich feed sources; in the EU-27, poultry farming consumes 24% of the total amount of protein-rich feedstuffs. Since the EU produces only 30% of the total quantity of protein crops used for feed, it is necessary to promote the use of traditional European protein crops (beans, peas) for feed in livestock farming. The research aim is to identify economic gains from the production of broiler chicken meat, replacing soybean meal with domestic faba beans and field peas in broiler chicken diets.
Adding field peas and faba beans to the broiler feed ration resulted in a significant live weight increase (5.74-11.95%) at the selling age, a decrease in the feed conversion ratio by 0.61-6.06%, and decrease in the product unit cost (15.34-37.06%) as well as an increase in the production efficiency factor (8.70-48.54), compared with the control group.
The optimum kind of legume species used in the broiler diet was peas, which were added in the amount of 200 g kg , resulting in live weight gain, a decrease in the feed conversion ratio and an increase in the production efficiency factor. © 2017 Society of Chemical Industry.
肉鸡日粮主要由谷物和富含蛋白质的饲料来源组成；在欧盟27国，家禽养殖消耗了富含蛋白质饲料总量的24%。由于欧盟生产的用于饲料的蛋白质作物总量仅占30%，因此有必要促进在畜牧养殖中使用传统欧洲蛋白质作物（豆类、豌豆）作为饲料。研究目的是确定在肉鸡日粮中用国产蚕豆和豌豆替代豆粕生产鸡肉所带来的经济效益。
与对照组相比，在肉鸡日粮中添加豌豆和蚕豆，在出栏时显著提高了活重（5.74 - 11.95%），饲料转化率降低了0.61 - 6.06%，产品单位成本降低了（15.34 - 37.06%），生产效率因子提高了（8.70 - 48.54）。
肉鸡日粮中使用的最佳豆类品种是豌豆，添加量为200 g/kg，可使肉鸡体重增加，饲料转化率降低，生产效率因子提高。© 2017化学工业协会。
