Effects of Level of Nutrition on Milk Yield and Composition Effects of Level of Nutrition on Milk Yield and Composition of Cows Fed Natural Grazing and Offered Different Supplements, in South Kordofan, Sudan ABSTRACT: Three feed ingredients that were locally used as supplements and fed to dairy cattle were offered to three groups of dairy cows while one group was considered as control and left on the natural grazing only and another one was offered a ration formulated to meet maintenance and production requirements. Milk quantity and its composition were monitored for 40 days. The results showed that supplementation of cows with 1.5 kg of any feed ingredient resulted in increment of milk production compared with those left on the natural grazing alone. Supplementation with oil seed cakes or cotton seeds was better as supplements than sorghum grains in promoting milk production. The highest performance was achieved with the group was fed 1.0 kg of formulated ration. The milk yield increased linearly (p
