Results From One And Two Implants Compared With Yearling Cattle On Summer Pasture, R. Pruitt, A. Fleck, E.F. Smith, L. Corah, Clenton E. Owensby Jan 1978

Results From One And Two Implants Compared With Yearling Cattle On Summer Pasture, R. Pruitt, A. Fleck, E.F. Smith, L. Corah, Clenton E. Owensby

Kansas Agricultural Experiment Station Research Reports

Reimplanting Ralgro in mid-July after implanting in late April did not improve daily summer gains compared to a single implant.


Weaning Calves Early From Drylot, M. Mckee, G. Fink Jan 1978

Weaning Calves Early From Drylot, M. Mckee, G. Fink

Kansas Agricultural Experiment Station Research Reports

Percentage Simmental and Hereford calves gained slightly more (13 lbs./hd) while nursing their mothers than 83 herd mates that were weaned early at 49 (+27) days of age. Percentage Simmental cows whose calves were weaned early had a higher conception rate than percentage Simmental cows that nursed calves (93% vs. 89%) Dams of calves weaned early rebred 17.6 days sooner than nursing dams.


Effect Of Aureomycin And Rumensin On Performance Of Finishing Heifers, Jack G. Riley, Ronald V. Pope Jan 1978

Effect Of Aureomycin And Rumensin On Performance Of Finishing Heifers, Jack G. Riley, Ronald V. Pope

Kansas Agricultural Experiment Station Research Reports

We used 210 yearling Hereford heifers to evaluate the efficacy of Aureomycin and Rumensin fed alone and in combination. Each product is cleared by the FDA for use in feedlot rations as an individual feed additive, however, additional clearance must be obtained to use the two products in combination in the same ration. Aureomycin effectively controlled live abscessed, and Rumensin improve feed efficiency by 8.7%.


Predicting Cattle Performance From Mathematical Models, B.E. Brent, A. Chestnut, P. George Jan 1978

Predicting Cattle Performance From Mathematical Models, B.E. Brent, A. Chestnut, P. George

Kansas Agricultural Experiment Station Research Reports

Tables based on a mathematical model are presented that allow cost of gains by steers at various weights to be calculated. An example illustrate how to use the tables to help with economic decisions.
