Effects Of Body Condition On Reproductive Performance Of Beef Cows, P.A. Momont, R.J. Pruitt
Effects Of Body Condition On Reproductive Performance Of Beef Cows, P.A. Momont, R.J. Pruitt
South Dakota Beef Report, 1986
Cows were fed differing nutritional levels before and after calving to create a wide range of cow body condition or fleshiness prior t o calving and at the beginning of the breeding season. Cows that were fleshier prior t o calving and when turned on pasture in early May (30 days prior t o the beginning of the breeding season) had a higher cycling rate in early May, June and July. Cows maintaining or increasing slightly in body condition (precalving to early May) tended to have a higher cycling rate during the breeding season than cows which lost body condition …
Effects Of Level Of Energy Supplement In Early Winter And Level Protein After Calving On Beef Cows Grazing Native Range, R.J. Pruitt
South Dakota Beef Report, 1986
Simmental-Angus crossbred cows grazing native range near Cottonwood, SD, were fed two precalving levels of energy supplement and two postcalving levels of protein supplement. Cow weight change and reproductive performance were similar for all treatments. Although calves from cows supplemented with higher levels of energy gained faster from birth to early May, gains to weaning were similar for all treatments.
