Blood profiles of Etawa crossbreed goats fed concentrates substitution diet with bread waste

Abstract

This study aims to determine the maximum level of the use of bread waste as a substitute for concentrates on feed utilization by livestock through blood profiles consisting of the amount of hemoglobin, erythrocyte numbers, hematocrit levels and leukocyte numbers. The material used in this study was 15 lactating Etawa crossbreed goats. The experimental design used was a randomized complete block design with 3 treatments and 5 replicates. The feed treatment given was forage and concentrate with a composition of 20:80 with ration treatments namely P1 = Silages 20% + Concentrates 64% + Bread waste 16% + Zeolite 2%, P2 = Silages 20% + Concentrates 56% + Bread waste 24% + Zeolite 2%, P3 = Silages 20% + Concentrates 48% + Bread waste 32% + Zeolite 2%. The observed variables were hemoglobin level (g/dL), erythrocyte count (million/μL), hematocrit level (%) and leukocyte count (thousand/μL). Data were analyzed using analysis of variance. The results showed that the treatment had no significant effect (P>0.05) on the blood profile which included hemoglobin levels, erythrocyte numbers, hematocrit levels and leukocyte numbers. Substitution of 24% bread flour in the ration gave the highest blood profile calculation results among the three treatments. The amount of Hemoglobin (g/dL) of P1, P2 and P3 were 8.88; 10.05 and 8.94. Erythrocyte numbers (million/μL). P1, P2 and P3 were 14.23; 15.92 and 14.59 respectively. Hematocrit levels (%) P1, P2 and P3 were 28.3; 30.98 and 28.72. Leukocyte numbers (thousand/μL) of P1, P2 and P3 were 13.68; 18.00 and 17.3. The conclusion of this study is that bread flour can be used as a substitute for concentrate up to 32% level in the ration and can maintain the blood profile of lactating Ettawa crossbreed goats in a normal state.
