| Abstrak Energy and protein requirements for the Donggala cow cattle in the late stages of gestation increase rapidly compared to the early gestation. This study aims to determine the effect of adding different protein sources to body weight gain and feed efficiency of late-gestation Donggala cattle receiving elephant grass and rice bran. The material used in this study were 16 tails of late-gestation female Donggala cattle with an age of about 3.5-4 years and a body weight range of 300-350 kg. This study used a randomized block design with 4 treatment feeds and each was repeated 4 times. The experimental feeds in this study were elephant grass (Pennisteum purpureum) ad libitum (P0), elephant grass ad libitum plus rice bran (0.5% body weight (BB), in the form of dry matter (BK)/day and 0, 5% BW/day and gamal leaf (Gliricidia sepium) (P1), oil palm cake (P2) and copra meal (P3). The variables observed were daily body weight gain (PBBH) and feed efficiency. The results of the analysis of variance showed that the feed supplemented with different protein sources had a significant effect on daily body weight gain of livestock. Mean daily body weight gain (PBBH) in treatments P0, P1, P2, and P3 were 0.41; 0.63; 0.74 and 0.82 kg/head/day Feed efficiency of Donggala cows at the end of gestation in treatment P0, P1, and P2 always increased with an average of 5.44, 5.61, 6.29 and 6.61, respectively. This shows that a good feed efficiency for Donggala cows at the end of gestation is in the treatment n P3 with a protein source in the form of copra meal.
