Abstract
One hundred twenty spring-calving Hereford x Angus cows grazing low-quality tallgrass-prairie forage during the winter of 1998 were fed a 43% crude protein supplement 2, 3, 5, or 7 days a week. Supplement was fed at 4 lb/head daily to cows supplemented daily. The other cows still received 28 lb per week but divided equally among feedings. Cumulative performance (measured by changes in body condition score and body weight) was slightly better with increased supplementation frequency. However, the magnitude of differences in body condition and body weight changes, even for the most extreme treatment comparisons, were relatively small.
Highlights
Where time allows and beef cows are accessible, they often are supplemented daily
Previous research at Kansas State University indicated that reducing supplementation frequency from daily to three times weekly caused only slight decreases in body weight and body condition scores
Our objective was to evaluate the impact of several supplementation frequencies on winter performance of range beef cows
Summary
Where time allows and beef cows are accessible, they often are supplemented daily. Previous research at Kansas State University indicated that reducing supplementation frequency from daily to three times weekly caused only slight decreases in body weight and body condition scores. Our objective was to evaluate the impact of several supplementation frequencies on winter performance of range beef cows. One hundred twenty Hereford × Angus cows were weighed and body condition was scored (1 to 9 scale) on December 7, 1998. Cows were stratified by body condition score and body weight and assigned randomly within the strata to one of three pastures. Cows in other treatments were offered 28 lb of supplement per week but evenly split among the supplementation events. Cows were weighed and body condition was scored again on January 8, on February 8, and
