Abstract
Maintaining Cow's critical bodyweight afier calving is crucial for better reproductive
performance. A village research on surge feeding by supplementing tree legume leaves to pregnant cow‘s teed was conducted at lowland in Pasuruan and up-land in Malang. Sixty farmers were randomly allotted in each location as collaborators. Tree legume leaves were fed to cow just after calving up to 3 months as much as 3.50 percent of body weight. The result shows that at lowland during 3 months observation the control group lost 40.95 kg per head while surge feeding
group lost only 18.00 kg per head. At upland location, the control group lost 28.00 kg per head and surge feeding group lost 20.70 kg per head The fact shows that the difference of body weight loss was greater at lowland than upland. This means that surge feeding tree legume leaves produced greater impact at lowland Reproductive performance was better for surge feeding group as indicated by average day of first estrus postpartum At lowland and upland the first estrus post
partum for control group was 101.42 days and 111.09 days after calving respectively. While for surge feeding it were 81 days and 63.58 days after calving respectively. An economic analysis showed that extra return could be generated for surge feeding.
