Detailed explanation-1: -The most satisfactory harvested forage for ewes is good quality alfalfa hay, although other high-quality legumes are almost as good. Alfalfa hay furnishes adequate protein, necessary vitamins and minerals. Other satisfactory harvested forages include legume-grass silage, corn silage and haylage (low-moisture silage).

Detailed explanation-2: -It is important to feed only sheep pellets to sheep. Cattle pellets often contain extra copper, which can be toxic for sheep. And feeding pig or poultry pellets to any ruminant animal is illegal (as they contain some meat or meat product).

Detailed explanation-3: -When forage is fed with the grain, additional evidence shows that whole grain is preferable to pellets. Feed intake is again higher, and the utilization of the forage is improved. The choice of grain will vary by location and in most northern regions, mixed grain or barley is probably the best for lamb feeding.

Detailed explanation-4: -By 10 weeks lambs weigh about 25 kg and their intake of grass will be adding to pasture requirements significantly. Typically they eat around 4% of liveweight per day which is around 1 kg of grass dry matter, increasing by 0.1 kg /week due to weight gain.
