Abstract/OtherAbstract:
|
1. Effects of early feeding with a diet containing added putrescine on duck intestinal development and growth performance were examined by a 2 x 2 factorial arrangement with two different feeding times (6 and 48 h) and two levels of putrescine (0 and 025%). 2. A significant main effect of early feeding on increasing body weight (BW) was observed from hatch to 35 d, whereas dietary putrescine had no significant effect on BW. 3. In the first week posthatch, enhanced small intestinal weight and intestinal density (weight of intestinal tissue/unit length of intestine), increased villus length and reduced crypt depth were observed in the early feeding group, while no effect was observed when putrescine was added to the diet. 4. Maltase and sucrase activity and protein/DNA ratio in jejunum were increased by early feeding in the first week, while decreased by putrescine supplementation. 5. In conclusion, early feeding methods have great potential for small intestine development and thereafter enhanced the growth performance of ducks, but dietary putrescine used during this period should be used cautiously to avoid toxicity. |
