Beef Cattle Commercial Feedlot Studies Trial 1—Effects On Steer Performance Of Variable Protein Levels, Implanting, And Worming, Jack G. Riley, K.F. Harrison, D.L. Good
Kansas Agricultural Experiment Station Research Reports
A 112-day trial used 280 mixed-breed yearling steers to study effects of varying protein levels in finishing steers rations. Crude protein content ranged from 15.1 percent for the first 28 days to 8.9 percent crude protein the final 28 days. Feeding a 15.1% crude protein ration for 28 days and a 13.2% crude protein ration the second 28 days or feeding a 13.2% crude protein ration for the first 56 days did not significantly improve total gain compared with feeding an 11.2% crude protein (control) ration.

Kansas Agricultural Experiment Station Research Reports
Six native Bluestem pastures and spring-calving cows were used to evaluate effects of burning and fertilizing pastures. Two pastures were controls, two were burned, and two were burned and fertilized with 40 pounds of urea nitrogen an acre applied aerially. Average daily gain of the calves did not differ significantly among pastures. Pounds of beef produced per acre was significantly higher from the burned, fertilized pastures, which supported heavier stocking rates with increased herbage production.

Effects Of Various Uterine Treatments On Calving-To-Conception Interval, G. Kiracofe, G.R. Brower, R.R. Schalles
Kansas Agricultural Experiment Station Research Reports
Cows were given intrauterine infusions of enzymes, antibacterials, bacteria, or a combination of enzymes and antibacterials after calving to study basic changes in the post-partum uterus and effect on rebreeding. The group given nitrofurazone, an antibacterial compound, had the highest conception rate; however, calving-to-conception interval was lengthened. Combining proteolytic enzymes with the nitrofurazone gave an intercal to conception similar to that of control cows. Nitrofurazone caused this uterine lining to erode. Combining enzymes with nitrofurazone prevented some of the erosion. Innoculating the uterus with bacteria (Lactobacillus acidophilus) after calving did not affect the calving-to-conception interval.

Kansas Agricultural Experiment Station Research Reports
Energy appears to be the limiting factor in the rations studied. Three lbs. of milo was superior to 1 1/2 lbs. of soybean meal when date of breeding was considered. In the second trial 3 lbs. of alfalfa and 6 lbs. of milo was superior to 3 lbs. of alfalfa hay and 3 lbs. of milo. Delaying feeding grain until after calving did not give satisfactory results. Possibly additional energy was supplemented too late to be effective.

Adapted Rumen Microorganisms (Arm) For Feedlot Cattle, Jack G. Riley, K.K. Bolsen, D.L. Good
Kansas Agricultural Experiment Station Research Reports
Two trials using 200 mixed breed steers were conducted to determine effects of 0,3, 6, or 12-ounce drenches of Adapted Rumen Microorganisms (ARM) on subsequent feedlot performance. An 85 percent concentrate ration was fed for 90-days before drenching with ARM. Steers receiving the 12-ounce treatment in trial gained 14.4 pounds more per head during the next 60-day feeding period. The 3 and 6-ounce treatments were less beneficial . The 12-ounce treatment in trial 2 produced a highly significant (P<.01) 15% increase in rate of gain and a 12.5% increase in efficiency compared with the control group.

Wind Chill For Cattle, D.R. Ames
Kansas Agricultural Experiment Station Research Reports
Cattle hides were exposed to cold-wind combinations ranging from -10 ÌŠF to 35 ÌŠF and 0 to 35 mph. Heat flow through hides (including hair) was measured and plotted as a function of wind velocity. Prediction equations for heat flow at different cold-wind combinations were formulated and compared with the human wind-chill index used by the U.S. Weather Bureau. Results indicate that wind-chill effects for humans and cattle are similar at low wind velocities (less than 25 mph) but differ at wind velocities greater than 25 mph. over the range of wind velocities studied, a cubic relationship was found for …

Kansas Agricultural Experiment Station Research Reports
Respiratory diseases of weanling calves are a continuous problem for ranchers. Each case is estimated to represent a $10 to $20 loss through veterinary costs, decreased gains, and death losses. There is also some question as to the effectiveness of certain preventative treatments. Few reliable experiments have compared medicative and management procedures of disease preventions. We evaluated preweaning vaccinations and weaning management practices.

Meat Shrinkage, J. Leising, H. Tuma
Meat Shrinkage, J. Leising, H. Tuma
Kansas Agricultural Experiment Station Research Reports
Meat shrinkage is a major problem for the beef industry. Shrinkage (loss in weight) results from many factors: improper chilling, low humidity, not packaging, poor sanitation, or excessive ageing time. Most beef is chilled overnight (16-20 hrs.) at cooler temperatures of 25 to 40 ÌŠF. internal temperatures after 20 hours chill vary from 55 ÌŠto 70 ÌŠF depending on cooler conditions and carcass weight. During a normal chill cycle, beef carcasses shrink 6 to 12 pounds or 1-2% for 600-pound carcass with the shrink depending on many cooler and carcass factors. Various methods have been used to reduce moisture evaporation …

A New Approach To Polioencephalomalacia (Pem), B.E. Brent, K.S. Lusby, J.A. Kobuszewski, J.C. Parks
Kansas Agricultural Experiment Station Research Reports
Polioencephalomalacia (PEM) is a disorder of the ruminant central nervous system characterized by sudden onset and rapid death. At autopsy, the brain may be swollen and cerebral cortex degenerated. Early symptoms may include disorientation and muscular in coordination. Affected animals may push against fences or other objects with their heads. More commonly, they are found dead or in a coma. If central nervous system damage is not excessive, animals with early symptoms respond to massive injections of thiamine, but may not recover coordination.

A convenient method to control flies in cattle manure is adding an insecticide to the ration. The chemical passes through the digestive tract and effectively controls fly larvae in the manure. It may also influence animal performance. We added an insecticide at 50 p.p.m. to a high roughage growing ration and to an all-concentrate finishing ration and measured performance by growth, feed intake, and feed efficiency in steers and heifers.
Starea, Urea, Or Soybean Meal As A Protein Source In Growing And Finishing Cattle Rations, L.L. Tucker, L.H. Harbers
Starea, Urea, Or Soybean Meal As A Protein Source In Growing And Finishing Cattle Rations, L.L. Tucker, L.H. Harbers
Kansas Agricultural Experiment Station Research Reports
Use of urea in beef cattle rations, particularly in rations containing high levels of roughage (growing-type rations), has been limited by urea's toxicity, segregation and mixing problems, palatability, and poor use by animals. We compared soybean meal, Starea® (44% protein equivalent), Starea ® (60% protein equivalent), a milo-urea pellet, and a urea-infused milo berry material as protein (nitrogen) supplements in growing-type rations. Animals used in a nitrogen-balance study were then fed a 70% concentrate ration, receiving the same sources of protein.

Kansas Agricultural Experiment Station Research Reports
During the winter of 1970-71, 63 six-year-old, non-lactating, pregnant Hereford cows were divided into eight groups to compare a soybean meal-sorghum grain supplement with supplements containing either urea, Starea 44 (an expansion-processed mixture of sorghum grain and urea), or sorghum grain only (Bulletin 546, 1971, p. 28). Cows were fed each morning six days a week, 7 days' feed each six days. They had access to water, a salt-mineral-vitamin mix (55.1% salt; 36.7% dicalcium phosphate; 8.2% vitamin A premix) fed free-choice, and native winter pasture (table 38).
