Abstract 

The effects of replacing corn and soybean meal with cocoa meal (CF) or palm kernel cake (PKC) in the concentrate on milk intake and yield of goats were evaluated. Five Saanen goats, averaging 2 kg daily milk yield at 60 days of lactation, were assigned to a 5 x 5 Latin square experimental design. The experiment lasted 14 days, with 10 days for adaptation period and four days for sample collection. Diets contained: 36% of roughage (corns silage) and 64% of concentrate, dry matter basis, formulated toyield 13.2% of crude protein. The treatments were as follows: 0, 15 and 30% CF or PKC, all with concentrate (corn and soybean meal). Dry matter, organic matter, crude protein, total digestible nutrients, total carbohydrates and nonfiber carbohydrates intakes decreased as affected by the highest replacement level (30% CF). No significant differences on neutral detergent fiber and ether extract intake were observed. Acid detergent fiber intake differed only between 30% PKC and 30% CF-based diets, with 0.94 and 0.59% body weight, respectively. The 30% CF-based diet showed lower milk production value, as kg/dia (1.208 kg), but similar to 30% PKC-based diet, when corrected for 3.5% fat. Replacing corn and soybean with CF and PKC in the diet of lactating goats is viable up to 9.13 and 18.81% dry matter, respectively.
