A research was done to study body performance responses of selected Donggala cows to different dietary crude protein content of concentrate feed. Twenty selected Donggala cows with an initial body weights range of 278.6(36.97) kg were used. The animals also had body condition score of 2.63(0.29), body length of 129.85(6.38) cm, shoulder height of 124.8(5.74) cm, bust of 157.45(8.7) cm, and hip width of 37.83(3.4) cm. The animals were arranged in a 4 x 5 randomized block design with 5 dietary treatments differing in crude protein content of concentrate feed (12, 14, 16, 18 or 20 percent). Animals grouping was based on their initial body weights. During the experiment which lasted for 8 weeks, the animals were fed on a ration consisting of 25 percent elephant grass and 75 percent concentrate mix. Results of the experiment indicated that total and daily animals body weight gain, and changes in body condition scores were significantly affected (P 0.05) animals body dimension measures. It may be concluded that the best dietary protein content of concentrate feed for an optimum body performance in Donggala cows before mating is 18 percent.
