摘要

Protein feed sources are becoming more and more limited worldwide. Soybean meal, as the primary and most reliable protein source, is becoming increasingly expensive; therefore, there is a need to look for economic alternative protein sources. This trial was conducted to evaluate the effects of graded replacement of soybean meal by sunflower seed meal (SSM) on the performance, egg quality, egg fatty acid composition, and cholesterol content in Rugao laying hens (a local breed). One hundred sixty 28-wk-old laying hens were randomly assigned to 4 groups of 40 birds. Each group was made up of 4 replicate subgroups, with 10 laying hens each. All birds were acclimated to the basal diet for 1 wk. Experimental diets contained 0 (control), 8.26, 16.52, and 24.84% SSM (ME, 8.50 MJ/kg; CP, 33.00%; Ca, 0.26%; P, 1.03%) replacing soybean meal. Feed and water were offered ad libitum for 6 wk. No significant difference (P
