Abstract In typical production system, rumi~lants derive most nutrients from forages. The system of raising cattle and sheep in the fanns of the Desert Development Center (DDC) of the American University in Cairo, depends mainly on grazing practices. Beef and lamb’s meat are produced from forage grazing animals. For acheving more efficient grazing operation, sheep graze on the same fodder crop area wllich has already been grazed by cattle. Alfalfa is the main fodder crop wllich is available all the year round. For better growth and production, additional supple~nentation of concentrates to grazing animals is often recommended. The objective of th~isn vestigation is to study the response of growing calves and lambs to energy supplementation under grazing system in desert agriculture. Two feedmg trials (on cattle and sheep) were carried out at South Tahnr in the farms of the Desert Development Center (DDC), of the American University in Cairo. |
