Effect Of Maturity At Harvest On Yield, Composition, And Feeding Value Of Forage And Grain Sorghum Silages, S. Hamma, B. Kirch, B. Downey, J. White, K. Bolsen Jan 1987

Effect Of Maturity At Harvest On Yield, Composition, And Feeding Value Of Forage And Grain Sorghum Silages, S. Hamma, B. Kirch, B. Downey, J. White, K. Bolsen

Kansas Agricultural Experiment Station Research Reports

In the last 2 years, three trials were conducted to determine the influence of hybrid and stage of maturity at harvest on silage yield, composition, and nutritive value for 15 forage and nine grain sorghum hybrids. Agronomic data, such as days to half bloom, plant height, and whole-plant dry matter (OM) and grain yields, were also obtained. In Trial 1, Pioneer 947, Acco Paymaster 351, and DeKalb 25E forage sorghum hybrids had different whole-plant OM and crude protein (CP) contents. Whole-plant OM increased, whereas CP generally decreased with advancing maturity. Hybrid affected both DM intake and CP digestibility. Results indicated ...


Grazing And Feedlot Performance Of Heifers Spayed By Two Methods, S.B. Laudert, Gerry L. Kuhl, A.J. Edwards Jan 1987

Grazing And Feedlot Performance Of Heifers Spayed By Two Methods, S.B. Laudert, Gerry L. Kuhl, A.J. Edwards

Kansas Agricultural Experiment Station Research Reports

Two field trials were conducted to compare the pasture and finishing performance of heifers spayed by the Kimberling-Rupp(K-R) technique or by flank spaying plus autografting a piece of ovarian tissue into the rumen wall (FS+A). In trial 1, neither spaying method resulted in gains of grazing heifers different from that of intake controls; however, FS+A heifers gained 5.1% faster than K-R spayed heifers. In trial 2, grazing gains of heifers spayed by the two techniques were similar. During the finishing phase, no performance difference was found among intact, K-R, or FS+A heifers in trial 1 ...


Effect Of Several Spaying Methods On Grazing Heifer Gains, Gerry L. Kuhl, T. Goehring, B. Ritter, S. Laudert, W. Mccully Jan 1987

Effect Of Several Spaying Methods On Grazing Heifer Gains, Gerry L. Kuhl, T. Goehring, B. Ritter, S. Laudert, W. Mccully

Kansas Agricultural Experiment Station Research Reports

Several spaying and ovarian autografting methods were tested in three field trials with 658 grazing heifers. None of the techniques examined were found to have a beneficial effect on heifer gains compared to intact controls. Heifers' initial weight, frame size, and body condition score were associated with cattle performance; however, their relative impact on gains varied across the three trials.


Effect Of Stocker Receiving Diet On Subsequent Pasture Gains, F. Brazle, Gerry L. Kuhl, D. Harmon Jan 1987

Effect Of Stocker Receiving Diet On Subsequent Pasture Gains, F. Brazle, Gerry L. Kuhl, D. Harmon

Kansas Agricultural Experiment Station Research Reports

Seven diets were fed for 27 days to newly arrived heifers to evaluate their impact on stocker gains during the receiving and pasture periods. The diets were as follows: soybean hulls plus soybean meal; suncured alfalfa plus wheat middlings; dehydrated alfalfa plus grain sorghum; distillers dried grain plus cottonseed hulls; brome hay plus 2 lb protein supplement/day; prairie hay plus 2 lb protein supplement/day; and a commercial receiving ration. During the receiving period, diets of soybean hulls plus soybean meal, distillers dried grain plus cottonseed hulls, and the commercial receiving ration produced the highest cattle gains. The soybean ...


Influence Of Rumen Bypass Fat Fed In A Range Supplement On The Performance Of Cows And Calves Grazing Bluestem Range, L. Corah, B. Cochran, D. Harmon, T. Goehring Jan 1987

Influence Of Rumen Bypass Fat Fed In A Range Supplement On The Performance Of Cows And Calves Grazing Bluestem Range, L. Corah, B. Cochran, D. Harmon, T. Goehring

Kansas Agricultural Experiment Station Research Reports

Adding rumen bypass fat to a range supplement reproductive characteristics, cow weight and condition performance during a 43-day postpartum feeding period.


Effect Of Supplemental Protein:Ratio On The Intake, Digestibility, Fill, And Turnover Of Dormant Bluestem Range-Grasses, T. Delcurto, R.C. Cochran, K.A. Jacques, D.L. Harmon, G. Towne, T.B. Avery, E.S. Vanzant Jan 1987

Effect Of Supplemental Protein:Ratio On The Intake, Digestibility, Fill, And Turnover Of Dormant Bluestem Range-Grasses, T. Delcurto, R.C. Cochran, K.A. Jacques, D.L. Harmon, G. Towne, T.B. Avery, E.S. Vanzant

Kansas Agricultural Experiment Station Research Reports

Feeding a low crude protein (12%) supplement depressed dormant bluestem range-grass fiber digestibility, whereas moderate (27%) and high (41 %) protein supplementation maintained forage digestibility and encouraged intake. Increased intake for moderate and high protein groups appeared to be associated with increased rumen dry matter and indigestible fiber fill.


Effect Of Terramycin® And Bovatec® In Free-Choice Mineral Mixtures On Gains Of Heifers Grazing Native Grass, F. Brazle, Gerry L. Kuhl, D. Harmon, S. Laudert Jan 1987

Effect Of Terramycin® And Bovatec® In Free-Choice Mineral Mixtures On Gains Of Heifers Grazing Native Grass, F. Brazle, Gerry L. Kuhl, D. Harmon, S. Laudert

Kansas Agricultural Experiment Station Research Reports

Supplementing heifers in an intensive-early grazing program with Terramycin ® or Bovatec ® in free-choice, mineral-soybean meal mixtures resulted in Comparable cattle performance. Both feed additive mixtures increased heifer gains about .3 lb per day compared to controls supplemented with a simple mineral mixture.


Effect Of Limited-Creep Feeding Calves Of Spring-Calving Cows Grazing Native Grass, F. Brazle, Gerry L. Kuhl, L. Corah, K. Zoellner Jan 1987

Effect Of Limited-Creep Feeding Calves Of Spring-Calving Cows Grazing Native Grass, F. Brazle, Gerry L. Kuhl, L. Corah, K. Zoellner

Kansas Agricultural Experiment Station Research Reports

Two limited-creep feeding trials were conducted with spring-born, suckling calves on native grass. The high-energy creep rations containing an ionophore were fed during the last 63 or 85 days before weaning in the two trials. Creep intake was limited with salt to about 1.5 lb per calf daily. Calves consuming the limited-creep feeds gained .26 to .31 lb more per head daily and required 4.4 to 5.5 lb of creep per lb of extra weaning weight.
