Abstract

In order to investigate the effect of dry sugar beet pulp on the performance of native geese, an experiment was conducted in completely randomized design in 5 treatments and 3 replications, 10 of male and female gosling in each replication. Five dietary treatments included the control group and diets with 5, 7, 10 and 15 percent of sugar beet pulp. During the breeding period, weight gain, feed consumption and feed conversion ratio were evaluated weekly. At the end of the experiment, two geese, one male and one female, were randomly selected from each replicate and killed for carcass traits. The results showed that in consecutive weeks, treats with different levels of sugar beet pulp had the highest average weight gain compare to control group (P<0.05). The treatments containing different levels of sugar beet pulp did not show any significant difference with the control group in terms of feed conversion ratio except for the 1-7 day breeding period. Using of sugar beet pulp reduced the weight percentage of thighs and increased the weight percentage of gut and viscera (P<0.05). The highest weight percentage of the carcass and the lowest weight percentage of gut and viscera were observed in the control group (P≤0.05). Also, the lowest weight percentage of back and neck is observed in the control group (P<0.05). In conclusion, considering of feed cost per kilogram of meat and the better performance of the bird, the use of sugar beet pulp up to 15% in the rations of geese is suggested.
