Comparison Of Dectomax And Valbazen On Beef Cattle Carcass Traits (2006), J.A. Christopher, T.T. Marston, J.R. Brethour, Gerald L. Stokka

Kansas Agricultural Experiment Station Research Reports

The objective of this trial was to determine if types of dewormers affected carcass characteristics. Crossbred steers (n=428) were stratified by weight and ultrasound marbling score and administered either Dectomax (subcutaneous injection) or Valbazen (oral) dewormer. Fecal egg counts indicated that both dewormers cleared internal parasites from the cattle. Carcass data indicated that Dectomax increased fat deposition as measured by 12th rib back fat; kidney, pelvic, and heart fat; and marbling score, when compared with Valbazen. Deworming products may affect carcass traits that are used to value cattle.

Influence Of Facilities On Cow Time Budgets (2006), Joseph P. Harner, John F. Smith, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

A model was developed to evaluate the impact of facilities on cow time budgets. The model suggests that in inadequate facilities overcrowding of the facility by 25% or more resulted because occupancy rate exceeded 100%. The model also is useful in evaluating the impact of time at milking center and milk-ing frequency on cow time budget. In general, the first groups of cows through the milking parlor will have adequate time for resting, feeding, socializing, and watering. The last groups of cows through the parlor, however, do not have adequate time for these activities if the time at the milking …

Efficiency Of Phosphorus Utilization In Dairy Operations (2006), Joseph P. Harner, Michael J. Brouk Jan 2006

Efficiency Of Phosphorus Utilization In Dairy Operations (2006), Joseph P. Harner, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

Efficient utilization of nutrients is a must on modern dairies. Most of the phosphorus arriving at the dairy will either be found in purchased feedstuffs or commercial fertilizer used to raise grain and forage for the dairy. In general, those dairies that purchase all feeds are more efficient with phosphorus utilization than those that grow forage and grain. This is likely due to increased inefficiencies associ-ated with feeding and crop enterprises. Care-ful evaluation of diets to reduce feeding ex-cess phosphorus can reduce phosphorus excre-tion in the manure by as much as 50%. This not only reduces input costs, but also …
