Abstract:

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.
