Influence Of Post-Ai Nutrition On Blood Urea Nitrogen, Progesterone, And Pregnancy, George Perry, Brandi Perry, Josh Nelson, Julie Walker, Cody Wright
Influence Of Post-Ai Nutrition On Blood Urea Nitrogen, Progesterone, And Pregnancy, George Perry, Brandi Perry, Josh Nelson, Julie Walker, Cody Wright
South Dakota Beef Report, 2007
Research has shown that changes in nutrition can have an effect on reproductive performance. Our objective was to determine the effect of post-AI nutrition on BCS, blood urea nitrogen (BUN), progesterone, and pregnancy rates. Forage-developed Angus-cross bred heifers (n = 336) were synchronized with the Select Synch+ Controlled Internal Drug Releasing device (CIDR) protocol (d -7 100 μg GnRH and CIDR; d 0 25 mg PG and removal of CIDR). Estrus was detected for 72 h and heifers bred by AI 12 h after being detected in estrus; heifers not in detected in estrus were bred by AI and given …

Effect Of Weaning Date On Performance Of Beef Cows, R. J. Pruitt, P. A. Momont
Effect Of Weaning Date On Performance Of Beef Cows, R. J. Pruitt, P. A. Momont
South Dakota Beef Report, 1994
Records from 92 mature crossbred cows calving in March and April were used to determine the effect of weaning calves 40 days earlier than the traditional weaning time on cow weight change, body condition, and reproductive performance. When calves were weaned early (September 14 versus October 231, their dams gained more weight from September 14 to early December and had higher body condition scores in December than the dams of later weaned calves. The two nutritional treaments imposed after calving were important in explaining the effects of earlier weaning on cow reproductive performance. For cows that were fed grass hay …

Serum D-Β-Hydroxybutyrate And Urea Nitrogen As Indicators Of Beef Cow Nutritional Status, P.A. Momont, R.J. Pruitt, R.H. Pritchard
Serum D-Β-Hydroxybutyrate And Urea Nitrogen As Indicators Of Beef Cow Nutritional Status, P.A. Momont, R.J. Pruitt, R.H. Pritchard
South Dakota Beef Report, 1988
Mature Simmental x Angus crossbred cows were fed differing levels of nutrition before and after calving (mid-March to early May) to determine if blood serum levels of d-β-hydroxybutyrate (BHB) and urea nitrogen (SUN) could be used as indicators of nutritional status. Visual condition scores and condition score change were used as subjective appraisals of cow nutritional status. BHB levels prior to calving were elevated for cows close to calving and those carrying male fetuses. SUN levels prior to calving were higher for thin cows that were losing body condition. If on a low plane of nutrition after calving, BHB values …
Effects Of Body Condition On Reproductive Performance Of Range Beef Cows, R.J. Pruitt, P.A. Momont
Effects Of Body Condition On Reproductive Performance Of Range Beef Cows, R.J. Pruitt, P.A. Momont
South Dakota Beef Report, 1988
Mature Simnnental x Angus crossbred cows were fed differing Levels of nutrition from December to May in each of 3 years to create a wide range in cow body condition or fleshiness at the beginning of the calving season (beginning mid-March) and when turned to summer pasture (early May)1 month prior to the beginning of a 60-day breeding season ( early June). Cows that were fleshier in March, May or June cycled earlier and conceived earlier. Being thin in May or June had a more detrimental effect on pregnancy rate for cows that calved late in the calving season. A …

Effects Of Body Condition On Reproductive Performance Of Range Beef Cows, R.J. Pruitt, P.A. Momont
South Dakota Beef Report, 1987
Simnental-Angus crossbred cows were fed differing Levels of nutrition from December to May in each of 3 years to create a wide range in cow body condition or fleshiness at the beginning of the calving season (beginning mid-March) and when turned to summer pasture (early May) 1 month prior to the beginning of the breeding season (early June). Cows that were fleshier in March, May or June cycled earlier. Cows that were fleshier at the beginning of the breeding season calved earlier the following years. For cows that calved Late in the calving season, body condition prior to calving, in …

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.
