Two management systems were evaluated in terms of the effects on
calf growth, on calf weight produced per cow per year, and on reproductive
performance of fall calving cows. The alternative management
systems tested were twin foster calf production and, delayed weaning,
production of single suckled calves weaned at the...
Two management systems were evaluated in terms of the effects on
cow condition score and body weight changes and calf growth rates. The
management systems evaluated were winter supplementation of energy,
winter creep feeding and delayed weaning. The calves used in this study
were born in September and October of...
A trial was conducted May 1 to September 4, 1989 at the Eastern
Oregon Agricultural Research Center (EOARC) Burns, OR to examine the
effects of strip or continuous grazing management on the diet and
performance of steers grazing native flood meadows. The objective was
to determine if strip grazing would...
Three studies were conducted to evaluate: 1) rotationally grazed forage for late-summer stockpiling; 2) effects of lactation on self-fed supplement intake; and 3) influence of cow age on hand-fed supplement intake. For the first study, treatments consisted of non grazed, 2X and 3X grazed. Crude protein of forage grazed 3X...
Traditional season-long livestock grazing strategy on western riparian areas
has been identified as one of the factors affecting rangeland productivity as well
as wildlife habitat in riparian zones. As alternatives to summer season-long
grazing, summer short-duration grazing (without haying), and fall short-duration
grazing (following haying), were considered in this study...
This study evaluated the influence of cattle stocking density on botanical composition of diet, diet preference, and cattle performance on the Zumwalt Prairie in Northeastern Oregon. In each of two years, 192 cow-calf pairs (549.27 kg, BCS = 4.89) and 48 yearling heifers (383.34 kg, BCS = 5.02) were stratified...
Two trials were conducted to evaluate changes in the quantity, quality, and moisture of available forage in the pasture, and shrub utilization by cattle during a 30-d late summer grazing period (Trial 1) and the effect of cow age (experience) on grazing distribution and diet composition (Trial 2) in mountain...
