South Dakota Beef Report, 1995
A study utilizing 64 Angus and Simmental multiparous beef cows was conducted to evaluate the administration of MGA-PGF on the onset of estrus, conception rate, and to determine blood serum hormone profiles (P, & LH). Cows utilized were at least 30 days postpartum and stratified by age, breed, and days postpartum into two groups: a treatment group (n=32) which received MGA orally for 14 days and a control group (n = 32) which did not receive MGA. Cows in the study were bled weekly for 9 weeks to monitor serum P, levels. Cows with serum P4 ≥ 1 ng/mL were …
Effect Of A Blood Meal/Corn Gluten Meal Supplement After Calving On Performance Of Cows Grazing Native Range, R. J. Pruitt, J. S. Heldt
Effect Of A Blood Meal/Corn Gluten Meal Supplement After Calving On Performance Of Cows Grazing Native Range, R. J. Pruitt, J. S. Heldt
South Dakota Beef Report, 1995
A spring grazing trial was conducted to determine the effect of a supplement with lower rumen degradability (sometimes referred to as escape protein or bypass protein) than soybean meal on cow and calf performance. Three supplement treatments based on corn, soybean meal and blood meallcorn gluten meal were fed to 70 Simmental-Angus crossbred cows grazing native range from early April to late May. There was no advantage to the escape protein as measured by cow weight change, reproductive performance or calf gain. Corn supplemented cows performed similar to soybean meal supplemented cows.
Evaluation Of Wheat Middlings As A Supplement For Beef Cows Grazing Native Winter Range, J. S. Heldt, R. J. Pruitt, R. H. Haigh, D. B. Young
Evaluation Of Wheat Middlings As A Supplement For Beef Cows Grazing Native Winter Range, J. S. Heldt, R. J. Pruitt, R. H. Haigh, D. B. Young
South Dakota Beef Report, 1995
Two winter grazing trials were conducted at the SDSU Cottonwood Research Station near Cottonwood, SD, to compare wheat middlings to soybean meal and corn-soybean meal supplements. In consecutive years, grazing trials from December to February were conducted using Simmental x Angus crossbred cows grazing two pastures with differing amounts of available forage and fed four supplemental treatments that were balanced to provide the following amounts of crude protein (Ib) and metabolizable energy (Mcal) per cow daily: 1) soybean meal .75 and 2.40, 2) low wheat middlings .75 and 4.76, 3) corn-soybean meal 1.50 and 9.40, and 4) high wheat middlings …
