Rearing Performance and Carcass Composition of Broiler Chickens Fed Rations Containing Guar Meal at Graded Levels

This study aimed to evaluate how different percentages of guar meal in feed rations for broiler chickens affect their rearing performance and carcass composition. The experiment was conducted a group one hundred sixty Ross 308 broilers randomly allocated four equinumerous groups (K, G4, G8 G12). birds were reared over 42 days with the application three feeding periods: starter (days 1–21), grower 22–35) finisher 36–42). All prepared using maize meal, soybean oil mineral vitamin additives. An experimental factor share rations: K—0%, G4—4%, G8—8% G12—12%. It demonstrated that higher percentage (8% or 12%) had negative effect on chickens’ weight gain intake. receiving supplemented featured conversion levels than those fed which only protein-rich component (p ≤ 0.05). Birds highest (12%) showed significant decrease chilled dressing compared other chickens. A an adverse birds’ muscularity. In addition, it meat DFD (dark, firm dry; pH1 > 6.4), but from dietary point view, contained smallest amount intramuscular fat. To sum up, 4% should be recommended chicken ensure satisfactory composition, including physico-chemical properties muscles.
