Effects of the Dietary Replacement of Soybean Oil with Rubber Seed Oil on the Growth Performance, Carcass Trait, and Status of Lipid Metabolism in Pekin Ducks

The objective of this study is to determine the effects dietary replacement soybean oil (SO) with rubber seed (RSO) on growth performance, carcass trait, and lipid metabolism in Pekin ducks. A total 160 1-day-old ducks were randomly allocated four experimental treatments fed diets different ratios SO RSO as follows: 3:0 (control), 2:1, 1:2, 0:3. Dietary supplementation had no effect their performance; however, it significantly decreased yield abdominal fat (p < 0.05). As increased, plasma TG, CHO, LDL-C, HDL-C contents Additionally, fat, triglycerides, cholesterol liver breast reduced Liver n-3 PUFA levels linearly increased 0.05), while n-6/n-3 increasing Moreover, resulted gene expressions FABP1, ME1, SREBP1c, FASN, DGAT2, HMGCR there was an expression ABCA1 0.05) In conclusion, deposition enhanced without affecting performance
