Abstract
A feeding trial of 3 months was conducted to study the growth performance of Malabari kids fed complete diets containing spent cumin (Cuminum cyminum) seeds. Eighteen Malabari kids of three to four months of age were procured from University Goat and Sheep Farm, Mannuthy and divided into three groups and randomly allotted with three complete rations. T1 (Control)- Complete feed containing CP- 16 per cent, TDN- 60 per cent, T2- Complete feed incorporating 10 per cent spent cumin seeds and T3 – Complete feed incorporating 20 per cent spent cumin seeds. All the dietary treatments were isocaloric and isonitrogenous. Average daily gain and total weight gain were 33.13 g and 2.78 kg, 40.67 g and
3.41 kg and 46.23 g and 3.88 kg, respectively for kids fed T1, T2 and T3 and the values were significantly higher in T3 compared to control but kids fed with T2 has similar growth rate as that of control and T3 group. Total dry matter intake of kids was 20.01, 21.65 and 24.75 kg, respectively for T1, T2 and T3 and they were similar. Feed conversion efficiency for kids fed T1, T2 and T3 was 7.23, 6.47 and 6.50, respectively and the values were similar. A digestibility trial of five days was conducted at the end of the feeding trial. Digestibility coefficient of nutrients in the experimental rations 68.17, 72.87 and 72.99 per cent for DM, 66.86, 74.12 and
73.88 per cent for CP, 56.99, 63.44 and 65.84 per cent for CF, 77.17, 77.84 and 81 per cent for EE, 75.78, 79.88 and 77.7 per cent for NFE, 49.29, 55.05 and 59.15 per cent for NDF and 36.94, 46.85 and 48.33 per cent for ADF for T1, T2 and T3, respectively. There was a significantly higher (p<0.05) DM and ADF digestibility in T2 and T3 compared with T1. Digestibility of CP and CF was significantly less (p<0.01) in T1 when compared to T2 and T3. There was no significant difference was observed among the groups in the digestibility of EE, NFE, OM and NDF studied. The haematological and serum biochemical parameters such as haemoglobin, serum total protein, calcium, phosphorus, Albumin, ALT, blood urea nitrogen and creatinine did not show any significant difference between the treatments and the values were within the normal range reported for the species. But the AST concentration was significantly higher in T3 compared to T1 and T2. However, the values were within the normal range reported for the species. The feed cost per kg body weight gain for the kids fed T1, T2 and T3 were Rs. 164.87, Rs. 136.09 and Rs.133.12, respectively and there was no difference in cost/kg gain between the groups. Critical evaluation of the results obtained in the present study revealed that kids fed with diet containing 20 per cent spent cumin seeds (T3) had significantly higher ADG and total body weight gain compared to control but kids fed with complete feed containing 10 per cent spent cumin seeds has similar growth rate as that of control and T3 group. Feed cost per kg gain for kids fed T3 was numerically better than control and similar to that T2 though not significant. Therefore, it could be concluded that spent cumin seeds at 20 per cent level can be included cost effectively in complete feed ration without compromising growth performance.
