This experiment was conducted to study the effect of whole cottonseed meal and whole unprocessed cottonseed as a source of protein in the lactating cows ration. Twenty-one, 75 percent Holstein Friesian milking cows were randomly assigned to 3 dietary treatments according to randomized complete block design. The cows were allowed to grazing in the pasture and received to feed supplements as fallowed: 1) commercial feed (control) 2) 50 percent of the whole cottonseed meal ration 3) 50 percent of the whole unprocessed cottonseed ration at the rate of 1 kg of concentrate per 2 kg of milk yield. Feeding trial lasted for 108 days. The result had shown that milk production and composition of milk from the cows fed whole cottonseed meal were significantly different (P0.05 ) from the cows fed whole unprocessed cottonseed ration. No significant difference between treatment means of feed intake to produce 1 kg of milk yield was obtained. The whole cottonseed meal ration cost was higher than the whole unprocessed cottonseed ration. However, the results indicated that the whole unprocessed cottonseed can provide an economic substitute for the protein source for the milking cow ration.
