This study was carried out to determine whether ruminal fermentation and serum acute phase protein concentrations differed between steers with and without pathology at slaughter. Ruminally cannulated steers (n = 28) were housed with noncannulated steers (n = 250) and randomly assigned to one of ...
Performance by feedlot steers and heifers: daily gain, mature body weight, dry matter intake, and dietary energetics. Performance, DMI, diet composition, and slaughter data from 9,683 pens of steers and 5,009 pens of heifers that were fed high-concentrate diets for 90 d or... R,A,Zinn...
FEEDING OF DEHYDRATED POULTRY MANURE TO STEERS ON PERFORMANCE, BLOOD AND URINE PARAMETERS AND LIVER DRUG-METABOLIZING ENZYME ACTIVITIES The effects of feeding dehydrated poultry manure (DPM) to steers during a 180-day finishing period on performance, blood and urine parameters and liver dru...

Two experiments evaluated carcass characteristics of finishing steers administered the maternal bovine appeasing substance (mBAS) prior to slaughter. In Ex... RF Cooke,NC Kertz,P Autumn,... - 《Journal of Animal Science》 被引量: 0发表: 2024年 Bamboozled: How Americans are being Exploited by ...
Four groups of 18 steers were individually offered ad libitum a pelleted diet that contained 0, 0·25, 1·0, or 4·0 ppm L-644,969 for 12 weeks prior to slaughter. L-644,969 quadratically increased carcass weight (3·7, 9·3, and 8·5%, P < 0·001) and altered the ...
In addition, previous studies reported that supplementation of RPF increased the nutrient digestibility such as protein, lipid or fiber in steers or ewes [38, 39]. Therefore, the greater ADG due to RPF supplementation could be explained by the greater DMI and nutrient digestibility. In this ...
Energy utilization, feedlot performance and fatty acid composition of beef steers fed protein encapsulated tallow or vegetable oils A comparative slaughter feeding trial was conducted with beef steers (initial weight 300 kg) to determine the energy utilization of diets containing protec...

A total of 117 finishing steers were blocked on weight and assigned to 13 groups of 9 animals each comprising a pre-experimental slaughter group and 12 finishing groups arranged in a 6 (feeding treatments) × 2 (durations of finishing) factorial experiment. The 6 feeding ...
Seven hundred sixty-two crossbred steers were used in a feedlot trial to determine the effect of V-Max; on performance, carcass characteristics, and the incidence and severity of liver abscesses. Finishing diets included either V-max; or the combination of Rumensin; and Tylan;. Performance was...
For example, in steers offered concentrates ad libitum over 132 days average daily live weight gain was 25% lower for the second half of the finishing period compared to the first half (Caplis et al., 2005). The decline in daily live weight gain can be attributed to an increase in gut ...
