The nutritive value and yield of forage legumes and barley harvested as immature herbage, hay and straw were measured in two experiments. The voluntary feed intake of peas at all stages of maturity and immature herbage from woollypod vetch was substantially lower than that of common vetch and chickling. At each stage of maturity barley was less digestible than all the forages except immature peas. Despite exceptionally cold weather in February/March 1985, yields of common vetch were higher in 1984/85 than in 1985/86 when there was less rain. Peas yielded the most hay, and chickling yielded less seed and straw than common vetch, peas and barley. Yields of digestible dry matter from straw and seed exceeded those from hay but protein yield at the two stages was similar. Mechanical baling substantially reduced the yields of baled hay but these losses would be reduced to less than 10% if the residues were grazed. E. F. Thomson, S. Rihawi y N. Nersoyan: Valor nutritivo y rendimientos de algunas leguminosas forrajeras y la cebada cosechados como herbaje inmaduro, heno y paja en al noroeste de Stria.R E S U M E N Se realizaron dos experimentos para medir el valor nutritivo y el rendimiento de las leguminosas forrajeras y la cebada cosechados como herbaje, heno y paja. La toma de alimento voluntaria de las arvejas en todas las etapas de madurez y el herbaje inmaduro de veza de vaina lanuda fue bastante inferior a la de la veza comun y la guija. En cada etapa de madurez, la cebada resulto menos digerible que todos los forrajes salvo las arvejas inmaduras. A pesar de un clima de excepcional fri'o en febrero/marzo de 1985, los rendimientos de la veza comun fueron superiores en 1984/85 a los correspondientes a 1985/86, cuando hubo menos precipitaciones. Las arvejas produjeron la mayor cantidad de heno, y la guija produjo menos semilla y paja que la veza comun, la arveja y la cebada. Los rendimientos de materia seca digerible en las dos etapas fueron similares. El prensado mecanico redujo considerablemente los rendimientos del heno prensado pero estas perdidas se reduciri'an a menos del 10% si se pastaran los residuos.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
