摘要：
Waste frying oil may serve as a viable alternative to fresh vegetable oils, potentially reducing environmental impacts and animal feed costs. This study aimed to assess the effects of incorporating waste frying oil into sheep diets and to determine the optimal dietary oil concentration. We evaluated intake and apparent d of age; 20 +/- 3.56 kg) in a randomized block design over a 21-d experimental period. The sheep were housed in individual metabolic cages and fed diets with a 50:50 roughage-to-concentrate ratio twice and 8% of the total dry matter. Animals receiving higher concentrations of waste frying oil exhibited lower nutrient intake (p digestibility decreased linearly (p < 0.05) with increasing oil content, except for ether extract digestibility (p = 0.02), which improved. nutrient intake and digestibility.
