Popis: | In Part I of a two-part study, an experiment was conducted to determine effects of post-extraction algal residue (PEAR) inclusion on nutrient utilization and carcass characteristics in finishing steers. Eighteen Angus × Hereford steers (initial body weight = 549 ± 38.8 kg) were randomly assigned to one of three treatments for the last 35 days prior to harvest: PEAR added to the ration at 1.0 kg organic matter (OM)/day (PEAR), or 1.0 kg OM/day glucose infused ruminally (GR) or abomasally (GA). The basal diet consisted of a standard finishing ration with additional roughage provided in the diet to prevent sudden changes in intake as a result of infusion treatments. Greater dry matter intake (DMI) was observed for PEAR (13.0 kg/d) than GR (10.3 kg/d; P |
