Abstract

Thirty-six dairy goats (16 Saanen and 20 Alpine) averaging 88 ± 2.3 days in milk were used in a complete randomized block design to evaluate the effects of whole soybeans on nutrient digestibility and on blood parameters. Does were fed corn silage based diets containing 0, 7, 14 and 21% whole soybeans for 63 days. Dry matter intake was linearly reduced (P<0.01). Apparent digestibility of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were linearly reduced (P<0.05). Crude protein (CP) and nonfiber carbohydrates (NFC) digestibility did not changed and ether extract (EE) digestibility had a quadratic effect (P<0.01) with increased whole soybeans. Whole soybeans added to diet increased (P<0.01) blood nonesterified fatty acid (NEFA) concentration before feeding and had no effect on blood glucose levels. Feeding with 21% of whole soybeans affected adversely nutrient digestibility.
