Utilization of Mixed and Complete Rations by Lactating Camels

Seven lactating camels (B.VVL 516.00±20.92 kg) in their second/third lactation were randomly divided into two groups. First group ‘MR’ of 3 camels was fed on mixed ration consisting of dry moth chara, dry khejri leaves and minerai mixture (74.3:25.0:0.7) while second group ‘CR’ of 4 camels was fed on complete ration consisting of dry moth chara, khejri, wheat straw and concentrate ingredients (35.3:25.0:30.0:9.7) for a period of 92 days. The MR lost 332.5g/d body weight while CR could achieve ADG of only 27.2g/d. Significantly higher (P<0.0l) digestibility of CP and EE were observed in CR as compared to MR camels. The DCP and TDN intakes (g/kg W^0.75) were 10.51 and 89.32g respectively in CR which were significantly higher (P<0.01) than the respective values of 4.88 and 63.83g in MR. The apparent absorption of sodium, potassium, calcium and phosphorus were similar between 2 groups except magnesium which was higher (P<0.01) in MR. Serum biochemicals and electrolytes did not differ between 2 groups except serum magnesium. It was significantly (P<0.01) higher in MR than CR which could be attributed to higher (P<0.01) Mg absorption (65%). It was concluded that feeding of complete ration maintained body weights, milk yield and improved nutrient utilization In lactating camels although higher cost was involved.
