Evaluation Of Reproduction And Blood Metabolites In Beef Heifers Fed Dried Distillers Grains Plus Solubles And Soybean Hulls During Late Gestation, Chanda L. Engel, H. H. Trey Patterson, Ron Haigh, Jason Johnson, Mindy Hubert, Brandi Perry, George A. Perry
South Dakota Beef Report, 2006
Dried distillers grains plus solubles (DDGS) contain a significant amount of both undegradable intake protein and fat, which have both been shown to increase reproductive performance when supplemented to heifers during gestation. The mechanisms leading to enhanced reproduction when fat or UIP are supplemented have not been fully defined. The objective of this experiment was to evaluate DDGS or soybean hulls (SBH) fed during the last trimester of gestation on circulating concentrations of growth hormone (GH) and insulin-like growth factor-I (IGF-I) and reproductive efficiency. Ninety-five crossbred heifers were grouped by expected calving date, BW, BCS, and randomly assigned to DDGS …
Corn Germ As A Source Of Supplemental Fat For Cows In Late Gestation, Dick Pruitt, Jeff A. Clapper, William B. Epperson, George A. Perry
Corn Germ As A Source Of Supplemental Fat For Cows In Late Gestation, Dick Pruitt, Jeff A. Clapper, William B. Epperson, George A. Perry
South Dakota Beef Report, 2005
To evaluate corn germ as a source of supplemental fat, 217 two to twelve-year-old cows receiving grass hay free choice were supplemented with either 2.75 lb of corn germ (dry basis) or an equal amount of crude protein from soybean meal (0.80 lb dry matter) starting approximately 50 days prior to the first expected calving. Cows were removed from treatment the day they calved and where managed as a group through the breeding season. Supplement treatment did not affect cow weight change or body condition score. Corn germ did not improve any measure of reproduction, including the percentage of cows …
Evaluation Of Dried Distillers Grains With Solubles As A Feedstuff For Heifers In The Last Trimester Fo Gestation, Chanda L. Engel, Hubert H. Patterson, George A. Perry, Ron Haigh, Jason Johnson
Evaluation Of Dried Distillers Grains With Solubles As A Feedstuff For Heifers In The Last Trimester Fo Gestation, Chanda L. Engel, Hubert H. Patterson, George A. Perry, Ron Haigh, Jason Johnson
South Dakota Beef Report, 2005
Ninety-six crossbred heifers were used in an experiment to evaluate the effect of dried distillers grains plus solubles (DDGS), fed in the last trimester of gestation, on heifer performance and reproduction. Animals were blocked by previous heifer development strategy (Antelope Research Station range developed = ANT 1; Antelope Research Station dry lot developed = ANT 2; Cottonwood research station = CTW), stratified by expected calving date, body weight and body condition score, and randomly allotted to one of twelve pens. Each pen was randomly assigned to one of two treatments (6 pens/treatment; 4 pens per block). Treatments were 1) dried …
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 …
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
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 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 …
Effectiveness Of Albendazole Against Parasites And Cow And Calf Performance, H.L. Miller, J. Berthelsen, B.A. Petitjean, R.H. Haigh
Effectiveness Of Albendazole Against Parasites And Cow And Calf Performance, H.L. Miller, J. Berthelsen, B.A. Petitjean, R.H. Haigh
South Dakota Beef Report, 1986
Albendazole was utilized in drench and feed additive form to determine its effectiveness against parasite control, cow weight and conception rate and calf weaning weights. Fecal oocyte number was decreased by administration of Albendazole. Calf weaning weights from treated cows were heavier the first two years (14.5 lb for heifers and 10.5 lb for bulls) but decreased the third year (13 lb and 6 lb for heifers and bulls, respectively). Conception rates were similar between the two groups, with the only difference occurring the third year when control cows had a higher conception rate from the second AI than treated …
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.
