    Lamb feeding experiments
    (Kansas Agricultural Experiment Station, 2011-04-28) Menzies, C.S.; Erhart, A.B.
    Lambs used were finewool wethers purchased from Phelps White, Roswell, New Mexico. Average purchase weight of 648 head was 75.8 lbs.; cost was $23.50 per cwt. Lambs were trucked to Garden City, arriving October. They sheared an average of 4.6 lbs. wool each October 27 and 28. Alfalfa hay and field chopped corn and sorghum forages were fed until lambs went on test. Total cost of lambs on test (initial cost, trucking, feed cost, and shearing charges minus estimated wool value) was $22.30 per cwt.

    Comparison of ram, wether and ewe market lamb slaughter and carcass characteristics
    (Kansas Agricultural Experiment Station, 2011-04-28) Kropf, Donald H.; Menzies, C.S.; Harrison, D.L.; Anderson, L.
    Lambs used were sired by Hampshire rams the first two years; by Hampshire, Suffolk, Southdown, Dorset, and Rambouillet rams the third year. All lambs were from western ewes and were individually slaughtered as they reached 95 lbs. Carcasses were graded and chilled carcass weights were obtained after a 48-hour chill. Fat thickness measurements were taken over the loin eye muscle at the ¼, ½, and ¾ points and loin eye cross-sectional area was determined.

    Changes in beef carcass composition with changes in animal weight and finish
    (Kansas Agricultural Experiment Station, 2011-04-28) Tuma, H.J.; Kropf, Donald H.; Kolstad, S.P.; Mackintosh, D.L.
    Information on animal growth and development, although complex and not fully understood, is necessary to determine the stage at which a beef animal will produce the most desirable carcass. True growth involves an increase in the structural tissues (muscle, bone and organs) and should be distinguished from increases by fat deposition. Optimum time to slaughter animals is when muscle growth and quality are at their most desirable combination.

    Improving beef cattle through breeding
    (Kansas Agricultural Experiment Station, 2011-04-28) Smith, W.H.; Schalles, R.
    The purebred Shorthorn cattle breeding project was continued during 1966 according to the original breeding program. Two inbred lives were established in 1949. The Wernacre Premier line is now in the fifth generation of inbreeding and the Mercury line, in the third generation. Inheritance of production traits in beef cattle are studied to evaluate effects of inbreeding and to explore the feasibility of using inbred lines to improve production traits of beef cattle.

    Sorghum grain as the only protein source in all-concentrate steer finishing ration; value of oyster shell in an all-concentrate ration
    (Kansas Agricultural Experiment Station, 2011-04-28) Smith, E.F.; Richardson, D.; Drake, C.L.; Brent, B.E.
    The National Research Council (publication 1137) recommends 10% protein (90% dry matter) to finish yearling steers. Sorghum grain in Kansas usually contains about 9 to 11 percent protein, although it may vary considerably depending on the variety, soil, weather and other variables (samples have ranged from 6 to 17%). Research has shown that under certain conditions, all-concentrate rations may be practical. Since low protein roughage is not used, a 10 percent protein ration can, in many cases, be formulations from sorghum grain alone.

    Investigations of milk-fat lamb production practices for western Kansas, Colby.
    (Kansas Agricultural Experiment Station, 2011-04-28) Menzies, C.S.; Banbury, Evans E.; Spaeth, C.W.
    A flock of approximately 450 commercial finewool ewes is maintained at the Colby Branch Experiment Station. Ewes are purchased in early spring in Southwest Texas as yearlings and replaced after producing six lamp crops. The current flock consists of ewes that produced first, second, and fourth lamb crops. Purebred Hampshire rams are used. All lambs are sold for slaughter.

    Time required to change yearling steers from roughage to high grain ration; using Stilbestrol as an implant and in the feed; worming yearling steers
    (Kansas Agricultural Experiment Station, 2011-04-27) Hall, M.C.; Smith, E.F.; Nelson, S.
    Sixty yearling steers were removed from bluestem pasture October29, 1965 and trucked six miles to the KSU beef cattle research barn where they received prairie hay and had access to a self-feeder of 50% bran and 50% dry rolled sorghum grain. October 30 they were weighed and divided into three lots of 20 steers.

    The effect on artery clamp for dehorning cattle
    (Kansas Agricultural Experiment Station, 2011-04-19) Drake, C.L.; Smith, C.W.
    Forty horned yearling heifers owned and fed by a cooperating feeder were used. Allotment was by gate cut into four groups of 10 each. Each group was weighed before being dehorned. Treatments follow: 1.) Control-not dehorned. 2.) Dehorned using clamp; arteries pulled. 3.) Dehorned without dehorning clamp; arteries pulled. 4.) Dehorned without dehorning clamp; arteries not pulled. After one hour, bleeding from several animals was so severe that dehorning clamps were used and arteries were pulled. All cattle were placed in on large lot and fed the same ration. The trial lasted 22 days.

    Poloxalene as a bloat preventative for beef steers grazing immature alfalfa
    (Kansas Agricultural Experiment Station, 2011-04-19) Drake, C.L.; Perry, H.B.; Smith, E.F.; Good, D.L.
    Poloxalene has proved to be an effective agent to prevent legume bloat in cattle, however, intake of the compound at regular intervals during the day is important. Intake twice daily at approximately 12-hour intervals has been shown to control bloat. This presents a management problem with beef cattle under most grazing conditions. This trial tested the effectiveness of poloxalene administered to beef cattle grazing immature alfalfa in a molasses-salt block and as “Bloat Guard” mixed with rolled sorghum grain fed free choice in a self feeder.

    Value of chlortetracycline-sulfamethazine supplementation for beef calves after being weaned and shipped
    (Kansas Agricultural Experiment Station, 2011-04-19) Drake, C.L.; Smith, E.F.; Perry, H.B.; Good, D.L.; Richardson, D.
    The number of cattle concentrated in small areas is increasing in Kansas. Conditioning new cattle is a major problem in some operations. This experiment studied effects of adding a combination of chlortetracycline-sulfamethazine on weight gain, feed efficiency and general health when fed to beef calves after they were weaned and shipped.

    Concrete and dirt surfaces compared for fattening beef cattle
    (Kansas Agricultural Experiment Station, 2011-04-19) Drake, C.L.; Smith, E.F.; Perry, H.B.; Lipper, R.I.; Larson, G.H.
    The Animal Husbandry and Agricultural Engineering departments cooperate in this project. The response of cattle with water applied as “artificial rain” on a concrete and a dirt surfaced lot is being studied. Ways to collect and handle feedlot runoff also are being studied. Two lots identical in size (42’ x 92’) were used. The dirt lot had a 16’ x 24’ concrete apron; both lots had fence-line bunks. Two trials are reported.

    The value of adding graded levels of gelatinized sorghum grain to a fattening ration
    (Kansas Agricultural Experiment Station, 2011-04-19) Drake, C.L.; Brent, B.E.; Deyoe, C.W.; Post, H.B.
    Reports from several experiment stations have aroused much interest in the value of “steam processing” or “flaking” grain for beef cattle. During the process, some gelatinization or cooking of the grain occurs. This trial studied the addition of various amounts of completely gelatinized sorghum grain to fattening steers rations.

    The value of sorghum grain, corn and wheat fed individually and in varying combinations in beef cattle finishing rations
    (Kansas Agricultural Experiment Station, 2011-04-19) Richardson, D.; Smith, E.F.; Brent, B.E.; Clary, F.G.
    Sorghum grain is the predominant grain produced in Kansas for livestock. In general, sorghum grain may be expected to produce a rate of gain similar to corn and greater than wheat when fed to beef cattle. However, it is not normally as efficient from the standpoint of pounds required per pound of gain. Two feedlot trials have been conducted to determine the value of feeding mixtures of sorghum grain and corn or wheat.

    Adapting roughages varying in quality and curing processes to the Nutrition of Beef Cattle: Urea vs. Soybean meal in wintering and finishing rations for beef steers
    (Kansas Agricultural Experiment Station, 2011-04-19) Richardson, D.; Smith, E.F.; Brent, B.E.
    It is generally recognized that a readily available source of energy (preferable grain) must be in the ration of ruminants for efficient synthesis of protein from nonprotein nitrogen. Therefore, nonprotein nitrogen has been used primarily in finishing (high grain) rations. Although urea is used rather extensively, there is practically no information on the minimum amount of readily available energy (grain) needed for efficient utilization. This test was designed to compare soybean meal (natural protein) and urea (nonprotein nitrogen) on an equivalent nitrogen basis in wintering and finishing rations of beef steers calves. During the wintering phase, they were fed sorghum silage (made from sorghum that produced 85 bu. Grain per acre), 2lbs of average quality alfalfa hay, supplement and 0, 3 or 6 lbs. of added grain. In the finishing phase, 2 pounds prairie hay per head daily replaced the sorghum silage. The alfalfa hay was continued and all animals received a full feed of sorghum grain.
