摘要
油脂作为一种高能饲料,一方面为动物提供必需脂肪酸和易被机体吸收利用的能量,另一方面可提高饲料适口性和转化率。但其在储存、加工和利用过程中易发生氧化酸败,日粮中氧化酸败的油脂会破坏畜禽正常的生理功能,降低机体健康水平,造成经济损失,同时导致畜产品存在安全隐患。主要就油脂的营养功能、氧化酸败的机理和日粮油脂氧化对畜禽机体的影响及油脂氧化防控措施进行阐述。
As a high - energy feed for animals, oil provides essential fatty acids and energy which is easily ly oxidized in the process of storage, processing and utilization. Oxidative rancidity of oil in diet can destroy the normal physiological function of animals, decrease the healthy level of the body, cause eco- nomic losses, and it can also lead to the potential safety problem of animal products. The nutritional func- tion of oil, mechanism of oxidative rancidity, the effects of oxidized oil on animals, and oil oxidation prevention and control measures were discussed.
