Growth Performance, Blood Lipid Profile, Relative Organ Weight and Meat Quality of Broilers Fed Corn-Soybean Meal Based Diets Containing Graded Levels of 1,3-Diacylglycerol

This 28-d feeding trial was conducted to evaluate the effects of dietary supplementation with different levels of 1,3-diacylglycerol (1,3-DAG) on growth performance, blood lipids profiles, relative organ weight and meat quality of broilers. A total of 512 male, one-d-old Ross 308 broilers with an average initial BW of 45.28 ± 0.81 g were randomly allotted to 4 treatments. Each dietary treatment consisted of 8 replicate cages, with 16 birds per replicate. The 4 dietary treatments were corn-soybean meal-based diets and supplemented with 0, 0.05, 0.10 and 0.15% 1,3-DAG, respectively. During d 1-14, with increasing the dietary 1,3-DAG levels from 0 to 0.15%, the body weight gain (BWG) was improved (linear, P
