The steady increase in the price of protein feed ingredients and the retraction of antibiotics from diets has encouraged nutritionists to search the alternatives for protein source and functional feedstuffs that can substitute the role of antibiotic growth promoters in poultry production. With crude protein of 24-30%, in vitro protein digestibility of 80% and proportion of essential amino acids of 47%, seed from ripe papaya may be exploited as the alternative protein feed ingredient for poultry. Moreover, the growth promoting effect, antimicrobial and antiparasitic activities, and immunomodulatory and antioxidative activities may confirm the potential of papaya seed as a functional feedstuff that could replace the role of antibiotic growth promoters for poultry. The in-depth study is needed to further elucidate the functionalities of papaya seed onpoultry. This review provides the updates on the nutritional contents of papaya seed, the potential of papaya seed as an alternative to conventional protein-rich ingredient, the growth-promoting effect of feeding papaya seed, the antimicrobial and antiparasitic activities of papaya seed, antioxidative activities of papaya seed, and the immunomodulatory activity of papaya seed on poultry.
蛋白质饲料原料价格的稳步上涨以及日粮中抗生素的停用，促使营养学家寻找蛋白质来源和功能性饲料的替代品，以替代抗生素生长促进剂在禽类生产中的作用。成熟木瓜种子粗蛋白含量为24 - 30%，体外蛋白质消化率为80%，必需氨基酸比例为47%，可作为禽类的替代蛋白质饲料原料加以利用。此外，其促生长作用、抗菌和抗寄生虫活性以及免疫调节和抗氧化活性，可能证实木瓜种子作为功能性饲料的潜力，它可以替代抗生素生长促进剂在禽类中的作用。需要深入研究以进一步阐明木瓜种子对家禽的功能。本综述提供了木瓜种子营养成分的最新信息、木瓜种子作为传统富含蛋白质成分替代品的潜力、饲喂木瓜种子的促生长作用、木瓜种子的抗菌和抗寄生虫活性、木瓜种子的抗氧化活性以及木瓜种子对家禽的免疫调节活性。
