Fermentation profiles and degradability measurements in extrusa diet samples collected from brome-suppressed and undisturbed pastures and their relationship to weight gain of steers

Autor: E. E. Grings, M. Blümmel, M. R. Haferkamp

Publikováno v: Canadian Journal of Animal Science. 84:105-111

The effects of suppression of annual bromes (Bromus japonicus Thunb. and Bromus tectorum L.) by atrazine application on the nutritive quality of extrusa diet samples (EDS) collected from the esophagus were investigated, and EDS quality estimates were

Efficiency of production in cattle of two growth potentials on northern great plains rangelands during spring-summer grazing

Autor: Michael D. MacNeil, Don C. Adams, M R Haferkamp, E E Grings, R E Short

Publikováno v: Journal of Animal Science. 74:2317

A study was conducted to evaluate the effect of sire growth potential, steer age, and cow size on intake, growth, and production efficiency in grazing cattle. Data were collected on 24 cow-calf pairs during each of four summers (1989 to 1992) and on

Effects of time of weaning, supplement, and sire breed of calf during the fall grazing period on cow and calf performance

Autor: R E Short, E E Grings, D. C. Adams, M R Haferkamp, R K Heitschmidt, Michael D. MacNeil

Publikováno v: Journal of Animal Science. 74:1701

A 4-yr experiment was conducted to determine effects of protein supplementation, age at weaning, and calf sire breed on cow and calf perfor- mance during fall grazing. Each year 48 pregnant, crossbred cows nursing steer calves ( x calving date = Apri
