Effect of fat sources and combinations on starter pig performance, nutrient digestibility and intestinal morphology.

摘要: Three growth trials and one digestion trial were conducted to compare the effect of dietary fat sources combinations on starter pig performance, nutrient digestibility intestinal morphology. Growth 1 2, utilizing a total 324 weanling pigs (21 +/- 3 d), determine influence addition soybean oil, coconut choice white grease, 50% oil: oil or grease: performance. Diets supplemented with 10% for first 2 wk study 5% final wk. The third trial, 210 pigs, was evaluate effects 75% 25% performance digestibility. Average daily gain feed/gain not changed during 0 but they improved from 5 postweaning when added diets. combination resulted in higher ADG than other combinations.
