Diverse combinations of forages with different nutrient profiles and plant secondary compounds may improve intake and nutrient utilization by ruminants. We tested the influence of diverse dietary combinations of tannin- (sainfoin-Onobrichis viciifolia; birdsfoot trefoil-Lotus corniculatus) and non-tannin- (alfalfa-Medicago sativa L.) containing legumes on intake and diet digestibility in lambs. Freshly cut birdsfoot trefoil, alfalfa, and sainfoin were offered in ad libitum amounts to 42 lambs in individual pens assigned to 7 treatments (6 animals/treatment): 1) single forage species (sainfoin [SF], birdsfoot trefoil [BFT], and alfalfa [ALF]), 2) all possible …

Consider the following scenarios: To cut the costs of ranching a researcher explores feeding cattle ammoniated straw in winter. Some of the cows maintain themselves on the diet while others lose weight, produce less milk and fail to conceive. A producer in Missouri plants a pasture rich in legumes and high in crude protein, yet his cattle prefer moldy hay and endophyte infected tall fescue to the legumes. Why do animals behave this way? Animals are thought to prefer foods that are palatable but what is palatability? We define palatability as the interrelationship between a food's flavor and postingestive feedback …
