Abstract: Alfalfa from the same plot harvested during the bud stage of maturity (early-cut) and again 2 weeks later (late-cut) during bloom stage was fed to three mature crossbred wethers. Net absorption of amino acids was determined by portal minus jugular concentration times the portal plasma flow adjusted to metabolic size. The animals were fed every 2 hr and received 90% of their ad libitum intake. Animals receiving early-cut alfalfa absorbed 7,440 mg/kg .7 S/day of amino acids as compared with 2,640 mg/kg-TS/day in animals receiving latecut alfalfa hay. The absorption of essential amino acids in mg/kg-7S/day was 6,072 and 2,136, respectively, for animals fed early and late-cut alfalfa. The dry matter intakes and nitrogen retention of animals receiving early-cut alfalfa were greater (P<.05) than those receiving late-cut alfalfa. |
