EFFECT OF COPPER SULPHATE AND ZINC SUPPLEMENTATION IN RATION ON GROWTH PERFORMANCE AND IMMUNE RESPONSE OF BROILER CHICKEN

Abstract

A feeding trial was conducted on 150 day-old Lohman meat broiler chicks for a period of 28 days in the poultry farm of Sher-e-Bangla Agricultural University, Dhaka. The aim of the study was to assess the efficacy of copper sulphate and zinc supplementation. The production indexes viz. feed intake, body weight, body weight gain, FCR, dressed weight, dressing percentage, internal organs weight, hematological parameters and survivability of broiler on three replication of five treatments group containing 10 birds each group was recorded and compared.The chicks were assigned to 5 treatments groups of T 1 (control), T 2 (antibiotic), T 3 (CuSo + Zn (8mg +30mg)) and T 4 (CuSo 4 + Zn (12mg +40mg)) and T 5 (CuSo 4 4 + Zn (16mg +50mg)) randomly.The results showed that there was significant difference (P<0.05) on the feed intake, final live weight, glucose, cholesterol, internal organs and hematological parameters among different treatment groups. The higher body weight found in CuSo

+ Zn (8mg +30mg)T treated group compared to other groups and values were followed in an ascending order in T 3 4 ,T 5 T 2 , and T group. The dressing percentage, body weight gain, feed conversion ratio, showed no significant (P>0.05) difference among all treatment groups. The better FCR (1.33±0.05) found inT 1 group. The dressing percentage in T (76.00±0.11) group was higher than other group. The result indicated that effects of supplementation of copper sulphate and zinc in blood constituents had significant effect except monocyte, eosinophil, basophil, and MCHC concentration which were non-significant (P>0.05). The control group (T 5 ) showed higher values of White blood cell (WBC) than other treated group. Higher feed intake found in T (2499.62±8.83g) group compared to other groups. However, superior final live weight (1856.67±78.38g) obtained in T 5 3 3 2 group where birds fed with CuSo

+ Zn (8mg +30mg) compared to those other treatment and control group. Birds fed with CuSo 4 + Zn (8mg +30mg)T 3 supplemented diet achieved superior result.
