摘要: Abstract The hypothesis tested by this study was that sheep with divergent estimated breeding values (EBV) for fleece weight differ in gut metabolism and anatomy; regardless of the level intake. Adult Merino wethers contrasting EBVs were fed at two levels intake 7-week periods a crossover design, where wool growth, anatomy evaluated. Regardless intake, genotype affected growth (P 0.05). Increases increased supply nutrients to animal measured end-products process (wool production, live weight, methane) independent genotype. results obtained indicate differences fermentation are not major cause production among different genetic merit when restricted intakes.
