中文摘要：
饲料加工过程中含水量的变化对饲料成品的质量、饲料加工效率以及动物的生长性能都有较大的影响。通过42 d的笼养试验考察了不同水分含量的颗粒料对肉鸡生长性能的影响。选用240只雄性罗斯334×708型肉鸡进行了单因素完全随机的笼养代谢试验,试验用育雏料、育成料和育肥料的水分含量13%、14%、15%和16%。结果表明：在0~14 d育雏阶段,颗粒饲料含水量对肉鸡平均日增重（ADG）、平均日采食量（ADFI）、饲料转化率（FCR）没有显著的影响。在15~35 d育成阶段,随着饲料水分的增加,肉鸡的ADG、ADFI降低,FCR升高,14%水分含量以上的颗粒料对肉鸡的ADG、AD-FI影响显著（P〈0.05）,对于FCR影响不显著（P〉0.05）。在36~42 d育肥阶段,随着饲料水分的增加,肉鸡的ADG、ADFI降低、FCR升高,14%水分含量以上的颗粒料对肉鸡的ADG、ADFI影响显著（P〈0.05）,15%水分含量以上的颗粒料对FCR的影响显著（P〈0.05）。
英文摘要：
Previous researches have shown that moisture content can affect feed quality, productivity and animal performance. In order to reasonably evaluate the effects of moisture content on broiler per- formance, a 42 d cage study was conducted. A total of 240 broiler chicks （10 birds per cage） were used in a randomized block design with male which includes 4 levels of moisture content（13%. 14%. 15% and 16%） of feed. The result shows that in the start period （1~14 d）, there were no significant ef- fects on ADG, ADFI and FCR. In grower period （15-35 d）, ADG and ADFI decreased following a lin- ear behavior with the increasing of moisture content, and the effects were significant when the mois- ture was over 14% （P〈0.05）. FCR increased with the increasing of moisture content, but the effects were not significant （P〉0.05）. In finisher period （36-42 d）, ADG and ADFI decreased following a lin- ear behavior with the increasing of moisture content, and the effects were significant when the mois- ture was over 14% （P〈0.05）. FCR increased with the increasing of moisture content, and the effects were significant when the moisture was over 15% （P〈0.05）.
