Conteúdo:  A 3 x 2 x 2 x 2 factorial experiment compared soybean meal, urea and biuret as nitrogen sources in lamb finishing diets, and the effect of steam treatment of corn, dehydrated alfalfa meal, diethylstilbestrol implants and their relationships on utilization of nitrogen sources. Steam treatment of corn did not increase rumen microbial activity as measured by concentrations and molar ratios of rumen VFA. Increasing nitrogen retention and lower blood urea nitrogen indiocate that the utilization of nitrogen from cracked corn may be affected by steaming. Steam treatment of corn resulted in 17% faster gains when soybean meal was the primary nitrogen source, but gains were 10% slower when urea was the primary nitrogen source. Steam-treated corn significantly increased carcass grade and dressing percent and lowered carcass shrink. Partial substitution of dehydrated alfalfa meal for dehydrated ground corncobs and lowering of the primary nitrogen sources markedly increased dry matter digestibility and nitrogen retention. This was associated with significantly higher concentrations of ruminal VFA. Lower blood urea nitrogen in conjunction with improved nitrogen retention indicates improved biological value of absorbed nitroegn. Improved dry matter digestibility and nitrogen utilization were reflected in 75% faster gains on 33% less feed per pound of gain and significantly improved carcass grade and yield. Response of lambs to dehydrated alfalfa meal was greatest for most criteria when ure... Mostrar Tudo
