  • Effects of protein level, calcium:phosphorous ratio and monensin on performance of finishing steers
    Durham, S.; Riley, J.; Pope, R. (Kansas State University. Agricultural Experiment Station, 1981)
    Ration crude protein levels of 10.4% and 12.0% were fed with or without monensin and with calcium-to-phosphorous ratios (Ca:P) of 1:2, 2:1, or 1:1. Steers fed 10.4% crude protein, a 1:1 Ca:P, and Monensin had highest average ...
  • The effects of Rumensin® and two levels of energy prior to calving on reproductive performance in first calf heifers
    Sprott, L.R.; Corah, L.R.; Riley, J.G.; Kiracofe, G.H. (Kansas State University. Agricultural Experiment Station, 1981)
    Heifers fed low energy diets gained less before calving, took longer from calving to first estrus, and dropped lighter calves. Their conception rates were lower and fewer showed estrus the first 20 days of breeding. Rumensin ...
  • Effects of Sila-bac and Silo Guard on alfalfa silage quality and corn supplementation on steer performance
    Bolsen, K.; Ilg, H.; Hinds, M. (Kansas State University. Agricultural Experiment Station, 1981)
    Inoculant (Sila-bac) and enzyme (Silo Guard) silage additives were evaluated with first-cutting alfalfa silage. Control and treated silages were made in 50-ton concrete stave silos and three types of experimental silos ...
  • The effects of stocking rate and level of winter supplementation on pregnancy rates in spring calving cows in the Kansas Flint Hills
    Sprott, L.R.; Owensby, C.E.; Corah, L.R.; Kiracofe, G.H. (Kansas State University. Agricultural Experiment Station, 1981)
    Pregnancy rates the first 40 days of breeding were lower in cows stocked at less than 6 acres/AU than in those allowed more grazing acres. Supplementation rate during the last 100 days of gestation had little effect on ...
  • Effects of weaning weight on reproductive performance in beef heifers
    Sprott, L.R.; Corah, L.R.; Kiracofe, G.H. (Kansas State University. Agricultural Experiment Station, 1981)
    Fertility during the first two breeding seasons was not affected by the dam's weaning weight, but lightest heifers at weaning reached puberty later, had smaller pelvic areas at calving, more difficult deliveries, had more ...
  • Ensila Plus and Cold-flo additives for corn silage
    Bolsen, K.; Ilg, H. (Kansas State University. Agricultural Experiment Station, 1981)
    Enzyme (Ensila Plus) and non-protein nitrogen (Cold-flo) silage additives were evaluated with whole-plant corn silage. Cold-flo increased ensiling temperatures 6 to 80 F during the first week. Growing steers fed Ensila ...
  • Factors affecting conception after synchronization with Lutalyse® and timed insemination
    King, M.; Kiracofe, G.H.; McKee, R.M. (Kansas State University. Agricultural Experiment Station, 1981)
    With heifers given two injections of Lutalyse 11 days apart, and inseminated 80 hours after the second injection, only 20% in heat before 48 hours conceived compared with 65% that were in heat 48 to 80 hours after injection. ...
  • Fat thickness as an alternative to marbling in beef carcass grading
    Dikeman, M.E.; Kemp, K.E. (Kansas State University. Agricultural Experiment Station, 1981)
    Data from 1669 steers show that equally palatable beef comes from carcasses with Choice marbling OR 0.4 inch of outside fat cover. Including cattle with 0.4 inch of fat and at least Slight marbling in a new choice grade ...
  • Feeding MGA to grazing heifers
    Corah, L.; Brazle, F.; Davidson, J. (Kansas State University. Agricultural Experiment Station, 1981)
    Feeding MGA to grazing heifers suppressed estrus but did not improve gain.
  • Four ear tags evaluated
    Sprott, L.R.; Corah, L.R. (Kansas State University. Agricultural Experiment Station, 1981)
    Four types of ear tags were evaluated for retention over 2 years. Retention was low for one type, and high for the other three types.
  • Growing rations of forage sorghum silage and alfalfa haylage
    Ilg, H.; Bolsen, K.; Dikeman, M. (Kansas State University. Agricultural Experiment Station, 1981)
    Growing rations containing forage sorghum silage (FSS) or equal amounts of FSS and alfalfa haylage were fed to crossbred steer calves for 112 days. Steers consumed more of the FSS + haylage but rate and efficiency of ...
  • Intermittent feeding of Chlortetracycline to finishing cattle
    Riley, J.; Pope, R. (Kansas State University. Agricultural Experiment Station, 1981)
    We used 168 yearling steers in a 139-day finishing trial to evaluate high levels of chlortetracycline (aureomycin) fed for short periods at regular intervals during finishing. Since liver abscess rate was low for all ...
  • NaOH and Ensila plus additives for wheat silage and alfalfa haylage for growing steers
    Bolsen, K.; Ilg, H.; Nuwanyakpa, M. (Kansas State University. Agricultural Experiment Station, 1981)
    Enzyme (Ensila Plus) and alkali (NaOH) silage additives were evaluated with whole-plant wheat silages which were fed with or without alfalfa haylage (45% moisture). Steers fed NaOH silage consumed the most feed but were ...
  • Nutritional effects of beef connective tissue characteristics and eating qualities
    Wu, J.J.; Kastner, C.L.; Hunt, M.C.; Kropf, D.H.; Allen, D.M. (Kansas State University. Agricultural Experiment Station, 1981)
    We compared taste panel and connective tissue characteristics of beef fed a high energy diet with beef fed grass. The high energy diet produced higher USDA quality and yield grades, more rapid weight gain, and increased ...
  • Performance and carcass traits of feeder calves scored for muscling, frame size, and condition
    Dikeman, M.E.; Allen, D.M.; Kemp, K.E. (Kansas State University. Agricultural Experiment Station, 1981)
    Calves with different USDA frame sizes had similar carcass composition and quality when slaughtered within the recommended weight range for their frame size. Large-framed calves had higher dressing percentages and ...

  • The toxicity of liquid supplements containing urea
    Bartley, E.E. (Kansas State University. Agricultural Experiment Station, 1981)
    Liquid supplement manufacturers must provide a product that is effectively utilized and is nontoxic. Toxicity can be reduced if the supplement's pH is below 3.8, but low pH alone does not improve nutritive value. A good ...
