Determination of protein and dry matter digestibility of diet in three plant meals by in-vitro study and their effect on broiler performance
Message:
Abstract:
The experiment was conducted to determine dry matter and protein digestibility of rations containing soybean meal، rapeseed meal and cottonseed meal by Hydroenzyme XP on in-vitro and effect on broiler performance. For determination of protein and dry matter ration digestibility prepared two samples from per diet. This three hundred Twenty-four day old Lohman chickens in three treatments by 4 replicates and 27 chickens in each that were modulated in complete random design (CRD). Treatments include: 30 percent of cottonseed meal، soybean meal and rapeseed meal. In soybean meal in-vitro protein digestibility were dramatically greater than cottonseed meal in both starter and grower diets (P<0. 05). In-vitro digestibility of dry matter was significantly higher in soybean and rapeseed meals than that in cottonseed meal in grower Period، (P<0. 05). Feed intake were dramatically greater in soybean meal than cottonseed meal (P<0. 05). Average body weight was significantly higher in chicks fed with soybean meal than rapeseed meal in grower Period (P<0. 05)، Also average body weight in chicks fed with rapeseed meal was greater than cottonseed (P<0. 05). Index of production increased significantly in chicks fed with soybean meal treatment in comparison to cottonseed treatment in grower period (P<0. 05). Breast weight was significantly higher in soybean and rapeseed meals than that in cottonseed meal in grower Period، (P<0. 05). Final results in this experiment have shown that showed that there is no significant difference between rapeseed meal and soybean meal treatments in many factors such as feed intake، breast weight and dry matter digestibility in 42 days of age.
