| Abstract | ||||
| The present research work was carried out at Maryout Research Station where results from feeding and metabolism Irials were utilized 10 investigate the energy required for maintenance of goats. Twenty male Sahrawi goats were used. The animals weights ranged from (25 t038 kg). Twelve experimental rations were formulated using barley grains, commercial concentrate mixture and wheat straw in order to achieve the planned varying levels of energy and OCP within the permissible DM intakes. The plan of feeding was to establish 12 combinations of TON and OCP levels eilher at recommended, above or below maintenance requirements of sheep. being. 27.8 9 TDNI Kg W 0.73 and 2.3 9 DCPlKgW 0.73. . Animal pe~orm~nce varied ~etween a weight loss of -0.18 to a ~in of +0. 12g/day/Kg. while nitrogen retention ranged from -104 to +386 mg/kg W' Iday. Appropriate regression models were used for the estimation of maintenance energy requirements for the maintenance of body weight. The predicted values were 32.11 g TDNII<.~ wo.73/day. 29.799 TDN/kg w07s/day, 491 KJ ME I kg w07J/day), 459 KJ ME Il<.g woo 5/day.141 kcal DE Il<.g Wo 73/day and 131 kcal DE II<.g WO.7S Iday. All these values were within the range recommended by several authors for other breeds of goats, but were slightly higher than those of Egyptian sheep. It is hoped that future experiments will determine the energy and DCP requirements for goats during their growth, lactation and pregnancy taking body composition into consideration. | ||||
