Conteúdo: | Conventional digestibility trials were conducted to evaluate relationships between forage intake and fecal physical characteristics of nine harvested forages of diverse chemical properties fed separately to steers. Fecal physical charactreristics evaluated were average daily defecation size (organic matter, percentage of body weight), average daily defecation frequency, and average daily fecal output (organic matter, percentage of body weight). Defecation frequency and fecal output were significantly (P<.05) correlated with forage intake (r = .81, r = .97, respectively). Based on our regression data, it appears forage intake (organic matter, percentage of body weight) for cattle can be predicted directly from total fecal output. However, this relationship shoulkd receive further study with a wider variety of forages since our data are onconsistent with other studies. Defecation frequency may have potential for monitoring trends and relative differences intakes of grazing ruminants.
