Factors affecting cost of gain of feedlot steers

Influence of Season of Birth and Post-weaning Pasture Gain on Feedlot Performance of Brahman Steers

Growing rate of gain on subsequent feedlot performance, meat, and carcass quality of beef steers.

Eighty Angus and Angus x Simmental steer calves were used in a completely random design to determine the effect of rate of BW gain during the backgrounding period on subsequent feedlot performance, carcass characteristics, Warner-Bratzler shear force (WBSF), and sensory analysis. Animals were stratified by BW and allotted randomly to 1 of 10 pens (5 pens/treatment). Dietary treatments were form...

Feedlot Closeouts for Holstein Steers

Feedlot closeout data is an important tool for measuring cattle performance and management practices for cattle production systems. Often, closeouts are quickly scrutinized by feedlot managers and cattle owners for economics and typical performance measurements and then filed. Unfortunately, a plethora of data that is reported in closeout reports is never adequately analyzed. A dichotomy of dat...

ALPHARMA Beef Cattle Symposium: Factors Affecting Feedlot Profitability

vide data on ruminal pH (pH = 6.21 ± 0.34), liquid outflow rate (LOR = 12.1 ± 4.0 L/kg DM), and ruminally digested OM (rdOM = 39.5 ± 10.3 % DM). The LOR is an index of buffer recycling/kg DMI and rdOM is an index of VFA production/kg DMI. The compliled data also included dry matter intake (DMI = 2.81 ± .87 % LW) and Acetate/Propionate ratio (A/P = 3.18 ± 0.89). Data were analyzed using GLM proc...

Salinomycin Levels For Feedlot Steers and Heifers

A new feed additive, salinomycin, was fed to 70 finishing steers (initial weight of 772lb) and 70 finishing heifers (initial weight of 4951b) for 139 and 145 days, respectively. Salinomycin was fed at 0, 5, 10, 15, and 20 g per ton of a ground corn based diet. Averaged across salinomycin levels, gain was increased 2.6 percent and efficiency of feed use was improved by 7.8 percent. Feed intake w...
