日粮中添加稻壳粉对雏火鸡生长性能、体尺指标、内脏器官发育和经济效益的影响

试验旨在研究日粮中添加稻壳粉对雏火鸡生长性能、体尺指标、内脏器官发育和经济效益的影响。选取体重接近的1日龄贝蒂娜雏火鸡100只，随机分成2组，每组5个重复，每个重复10只，公母各半。对照组饲喂基础日粮，试验组饲喂添加稻壳粉的基础日粮，试验期8周。结果表明，与对照组相比，试验组平均日采食量（ADFI）无显著变化（P>0.05），但体重及平均日增重（ADG）极显著显著增加（P<0.01），料重比极显著降低（P<0.01）；试验组心脏重有增加的趋势（P=0.09），腺胃重显著增加（P<0.05），肌胃重极显著增加（P<0.01）；试验组和对照组体尺指标、脏器指数、肠道重量和长度均无显著差异（P>0.05）。56日龄时，试验组每只火鸡比对照组经济效益提高39.4%。综上所述，在雏火鸡日粮中添加稻壳粉，具有提高雏火鸡生长性能及经济效益的作用。

Effects of Rice Husk Powder on Performance,Body Size Traits,Internal Organs Development and Economic Benefit of Young Turkey

The purpose of this experiment was to study the effect of adding rice husk powder on the growth performance, body size traits, development of internal organs and economic benefits of young turkey. 180 young turkeys with similar body weight were selected and randomly divided into two groups, with each group having 5 replicates, each replicate of 10 birds. The control group was fed with basal diet, the experimental group was fed with basal diet added rice husk powder. The experiment lasted 8 weeks. The results showed that there was no significant difference in avarage daily feed intake (ADFI) between control group and experimental group (P>0.05).Compared with control group, the body weight and avarage daily weight gain (ADG) of the birds in experimental group increased extremely significantly (P<0.01), while the ratio of feed intake and daily weight gain (F/G) decreased extremely significantly (P<0.01); The heart weight of the birds tended to increase (P=0.09), whereas the proventriculus weight significantly increased (P<0.05), and the gizzard weight extremely significantly increased (P<0.01) in experimental group. There were no significant differences in body size traits, organ index, intestinal weight and length of the birds between control group and experimental group (P>0.05). The economic benefit of each bird in experimental group at 56 days of age was increased by 39.4% compared with control group (P<0.05). In summary, adding rice husk powder in young turkey's diets could improve the growth performance and the economic benefits of turkey.
