Small intestine morphology, growth performance and nutrient digestibility of young broilers affected by different levels of dietary putrescine.

摘要: This experiment was conducted to investigate dietary putrescine effects on broiler performance. Treatments were 6 levels of (0, 0.01, 0.02, 0.03, 0.04 & 0.05 %) added a basal diet and fed 4-32 day old broilers. The weekly growth performance recorded, ileal digesta small intestine samples collected at the end 2nd 3rd week age. At 21 d, body weight feed intake increased with 0.03 0.01% supplementation respectively, while conversion ratio not affected. younger age (14 d), decreasing putrescence BW energyprotein digestibility seen.
