Abstract :

Study was conducted to evaluate the effect of different energy rations on their growth performance and carcass characteristics in Kamori goat kids. Kids were grouped into A, B and C groups each consisting of 6 kids. Group A (Control) was fed Medium energy (ME) 2.37 Mcal/kg, group B were fed High Energy (HE) 2.56 Mcal/kg, and group C was fed Low Energy (LE) 2.18 McCall/kg ration for 60 days. Average live weight gain and average daily gain was significantly higher (P<0.05) in group B whereas daily feed intake and feed conversion ratio was significantly lower in group B. The average dressed carcass (Kg) and average dressing percentage was significantly higher (P<0.05) in group A and B than Group C. Group A & B showed significantly higher (P<0.05) hematocrit value. Hemoglobin percent was significantly higher (P<0.05) in group C. TLC was significantly lower in group B than in group A and C. Neutrophils, eosinophils, monocyte, platelet, MCH, MCHC values did not differ significantly (p>0.05) in all groups. Lymphocyte count significantly higher in kids fed with low energy ration as compared to medium energy ration. The MCV of Kamori goat kids in group C was significantly higher than group A and B. There was no significant difference between MCV values of group A and B. Significantly higher (p<0.05) glucose level was in group B followed by group A (control) and group C. There was no significant difference in serum protein levels between all groups. Cholesterol level was significantly higher (P<0.05) in group A & B than C. Uric acid was significantly (P<0.05) higher in group A. No significant difference was observed in BUN between all groups. There was no significant difference in between Net Revenue from Control and Kid feed with H.E. Whereas net loss in revenue was observed in group C fed with low energy rations. It was therefore concluded that feeding high energy ration could be beneficial for goat production. Keywords: Energy, Performance, Carcass characteristic, hematology, Kamori goat Kids
