Abstract
An on farm investigation has been done from March to September 2023 to investigate local feeds commonly offered for Madura cattle in Bangkalan regency, as well as their feeding value. Socah village was purposively selected in which a total of 30 cattle farmers were designated as location of this study. The observations being made were type of feeds offered, their nutrient content and feeding value as measured for late pregnant cows. Local feeds identified were used to formulate a ration Madura cows in the stage of 7-8 months pregnancy (30 cows) and a comparation was made between those fed on field grass plus rice bran as control group (10 cows), and the other two treatments (B and C) in which 1,0 kg and 2,5 kg of concentrates were used accordingly. The results showed that local feeds commonly used by farmers were as follow: agricultural byproducts (rice straw, maize stover, groundnut peel, mungbean straw, and sweet potatoe leaves, cassava leaves), fresh forages (elephant grass, Indigofera, Sesbania, and Leucaena leaves), concentrates (rice bran, maize bran, tofu waste and soybean hulls). Cows that were given field grass supplemented with concentrate consisted of rice bran (40%), tofu waste (19%), maize bran (31%) and soybean hulls (10%) 45 days before and after calving produced heavier calves than control (21.4, 24.3, 19.4 kg repectively). Cows that were given concentrate supplementation showed shorter open days (81.6 and 71.6 days for treatment b and C) than treatment A (107.3 days). It can be concluded that under better feeding management system through concentrate supplementation resulted in heavier calves at birth and the cows showed oestrus earlier than control group.
