饲粮能量水平对产蛋前鹌鹑生长发育的影响

The Effect of Different Energy Level in Feed on Growth and Development of Quails before Laying Period

试验研究了不同能量水平饲粮对蛋鹌鹑产蛋前体重的影响。试验分3个处理组，产蛋前鹌鹑分育雏期（O～18d）和育成期（19～39d）2个阶段，各组饲粮代谢能水平分别为：A组，育雏期11．70MJ／kg，育成期11．40MJ／kg；B组，育雏期12．20MJ／kg。育成期11．90MJ／kg；C组，育雏期12．70MJ／kg，育成期12．40MJ／kg。结果表明，A组育雏期末体重极显著高于B、C组（P〈O．01）；A组育成期末体重最高，且极显著高于C组（P〈O．01），A组在产蛋前期，各阶段累计采食量均大于B、C组。饲粮低代谢能水平的A组鹌鹑生长发育最好。

Two groups of quails at rearing stage（0N 18 d）and grown stage（19～39 d） were fed under different energy levels in feed to study the effect on their body weight. The results showed that the body weight of quails at rearing stage underll. 70 MJ/kg of metabolized energy level in feed was very significantly higher than that of quails at rearing stage under 12.20 MJ/kg and 12.70 MJ/kg of metabolized energy level in feed and the body weight of quails at grown stage under 11.40 MJ/kg of metabolized energy level in feed was very significantly higher than that of quails at grown stage under 12.40 MJ/kg of metabolized energy level in feed. The accumulation intake of quails before laying period under 11.70 MJ/kg（at rearing stage） and 11.40 MJ/kg（at grown stage）of metabolized energy level in feed was higher than other two treatments, which indicates the low metabolized energy level in feed is beneficial to growth and development of quails.
