Item Open Access Corn vs. sorghum, pellets vs. meal, and soybean oil meal vs. a mixed protein for growing-finishing pigs(Kansas Agricultural Experiment Station, 2011-05-06) Koch, B.A.One hundred forty feeder pigs weighing approximately 60 to 80 pounds each and averaging 12 weeks of age were randomly divided by weight into groups of 14 pigs each. The pigs had been vaccinated previously for hog cholera and had been wormed with piperuzine. All pigs had been on concrete from birth and they had been raised under complete confinement. Each group of 14 pigs was placed in a pen 7 feet wide by 28 feet long with 16 feet of the pen under roof. Complete rations, either meal or pellets, were self-fed. An all-steel three-hole self-feeder was used in each pen. Water was always available from automatic waterers.Item Open Access Kansas Swine Improvement Association Testing Station(Kansas Agricultural Experiment Station, 2011-05-06) Koch, B.A.; Moyer, W.A.The seventh group of pigs tested in the Kansas Swine Testing Station completed their test during the 1961-62 winter. The Animal Husbandry Department and the Extension Service cooperation in manging and supervising the station. All expenses incurred in testing are paid by breeders or producers who have pigs tested.Item Open Access Antibiotics in swine growing-finishing rations(Kansas Agricultural Experiment Station, 2011-05-06) Koch, B.A.; Yu, J.T.Pigs used were both barrows and gilts, either Duroc or Black Poland China breeds. All pigs used in the study were approximately the same age when they went on test. The heavier pigs were assigned to lot 4. They were self-fed the basal ration listed in Table 22 while confined on a concrete floor. The ration was ground and pelleted. Water was available from automatic waterers at all times. For nozzles were use dot keep the pigs cool during warm weather. Individual pigs were removed from the test pen when they weighed approximately 230 pounds.Item Open Access Garden City lamb feeding experiments(Kansas Agricultural Experiment Station, 2011-05-06) Hillman, M.; Erhart, A.B.; Menzies, C.The 638 white-face feeder lambs used in these tests were received October 18, 1961, at the Zuni Indian Reservation south of Gallup, N.M. Average purchase weight was 71.2 lbs. per head. They arrived in Garden City, October 20, and weighed 64.1 lbs. per head off the cars.Item Open Access The effects of feeding different levels of dicalcium phosphate to heifers on bluestem pasture(Kansas Agricultural Experiment Station, 2011-05-06) Drake, C.L.; Smith, E.F.; Richardson, D.; Good, D.L.; Follis, D.L.This trial was designed to study the effects of low to high levels of calcium and phosphorus supplementation for heifers grazing bluestem pasture. Forty Hereford heifer calves were divided into four groups at random, and turned into a 140-acre pasture. Each morning the heifers were gathered and separated into four lots and fed the rations shown in Table 14.Item Open Access Improvement of beef cattle through breeding methods(Kansas Agricultural Experiment Station, 2011-05-06) Smith, W.H.; Wheat, J.D.; Spies, H.; Gottlieb, H.A.The purebred Shorthorn cattle breeding program was continued during 1961 according to the breeding program initiated in 1949. Inbreeding of the two lines has been continued. The Wernacre Premier line is in its fourth generation, and the Mercury line will enter its fourth generation of inbreeding during 1962. The inbreeding plan has been basically to continue successive generations of half-sibbing in both lines.Item Open Access Trace-mineral salt for steers on a fattening ration (Concrete and shelter vs. dirt and no shelter) with observations on shrink(Kansas Agricultural Experiment Station, 2011-05-06) Koch, B.A.; Smith, E.F.; Richardson, D.; McCartor, M.M.Previous data reported from this station seem to indicate that supplemental dietary trace minerals may be valuable under certain feeding conditions. Those data also indicated that trace minerals might be related to weight loss during shipping. This study was designed to further determine the value of supplemental dietary trace minerals when cattle were on concrete and had shelter available and when they were on dirt with no shelter.Item Open Access Different methods of managing bluestem pastures(Kansas Agricultural Experiment Station, 2011-05-06) Smith, E.F.; Anderson, K.L.; Koch, B.A.; Drake, C.L.; Boren, Fred W.This experiment was designed to determine the effect of different stocking rates, of deferred grazing, and of pasture burning on cattle performance, productivity of pastures, and range condition as determined by plant population changes. In addition to the yearly report, a summary of cattle gains for the past 12 years of the study is included.Item Open Access Response of fattening steers to oral or injected vitamin A, with observations on shrink(Kansas Agricultural Experiment Station, 2011-05-06) McCartor, M.M.; Koch, B.A.; Smith, E.F.; Richardson, D.; Cox, R.F.Steers used in an antibiotic study and a trace mineral study reported elsewhere in this publication were also used in a study designed to further evaluate the use of supplemental vitamin A during the fattening period. The animals used showed no visual symptoms of vitamin A deficiency any time. However, the diets fed and the management practices followed were similar to those in studies at other stations where supplemental vitamin A was evaluated.Item Open Access Field-conditioned alfalfa hay as it affects the winter performance of weaned heifer calves(Kansas Agricultural Experiment Station, 2011-05-06) Smith, E.F.; Richardson, D.; Fairbanks, G.E.; Thierstein, G.E.; Follis, D.L.; Boren, Fred W.Through cooperative efforts of the Departments of Agronomy and Agricultural Engineering, fourth-cutting alfalfa hay was made available to winter-feed weaned heifer calves. The object of the experiment was to determine the effects of various field-conditioned alfalfa hays on the winter performance of heifer calves.Item Open Access The relation of feathering and overflow fat of lamb carcasses to the grade of the lamb, degree of marbling, and market value of the lamb(Kansas Agricultural Experiment Station, 2011-05-06) Mackintosh, D.L.; Merkel, R.A.; Menzies, C.S.This project was undertaken the spring of 1960 to attempt to determine the relationship, if any, of internal fats, overflow, and feathering to the degree of marbling in the longissimus dorsi muscle, the grade of the carcass, and the relationship of marbling to the palatability of the meat. Eighty-eight lambs were slaughtered in 1960: 120 in 1961; and about 80 will be slaughtered this spring.Item Open Access The value of enzyme preparations added to beef cattle rations(Kansas Agricultural Experiment Station, 2011-05-06) Richardson, D.; Smith, E.F.; Koch, B.A.; Boren, Fred W.This was our second test to determine the value of various enzyme preparations added to beef cattle rations. The first involved amylase and a combination of amylase and protease. Amylase apparently depressed the appetite or feed consumption, which resulted in decreased rate of gain. The combination of amylase and protease appeared to increase rate of gain at the beginning of the test; however, gains decreased as the test progressed and ended with the average daily gain being less than for control animals. This test involved a combination of amylase and protease and also this combination plus cellulose in the wintering phase. One lot received protease only in the fattening phase.Item Open Access The relation of packaging material to the keeping quality of frozen pork(Kansas Agricultural Experiment Station, 2011-05-06) Mackintosh, D. L.; Merkel, R.A.; Hall, J.L.; Harrison, D.L.; Anderson, L.Fresh pork sausage is used by an increasing number of families with home storage units. Several years of research here indicated that with salt, pepper, and sage added before sausage is stored, its maximum storage life is 6 to 9 months at 0 F, and then only when tested packaging materials are used.Item Open Access Heritabilities, genetic, and phenotypic correlations between carcass and live animal traits in sheep(Kansas Agricultural Experiment Station, 2011-05-05) Hillman, M.; Menzies, C.S.; Wheat, J.D.; Mackintosh, D.L.; Merkel, R.A.This is a continuous project to the North-Central-50 Regional Sheep Breeding Project. The Kansas State Project was initiated to determine relationships between various carcass measurements and live animal traits, to estimate heritability of these traits, and to determine how findings may be applied to selection and breeding of meat-type lambs.Item Open Access Diethylstilbestrol implant plus oral Chlortetracycline vs. Oral Chlortetracycline alone for fattening steers(Kansas Agricultural Experiment Station, 2011-05-05) McCartor, M.M.; Koch, B.A.; Smith, E.F.; Richardson, D.; Cox, R.F.Hereford steers used in this study were fed in outdoor dirt lots without shelter. Each steer in lot 23, described in a trace-mineral study reported elsewhere in this publication, received a 24-mg. implant of diethylstilbestrol on the first day of the feeding period. Steers in both lots received 70 mgs. of oral chlortetracycline each day during the feeding period.Item Open Access The effects of added protein to dry rolled and steam rolled sorghum grain fattening rations(Kansas Agricultural Experiment Station, 2011-05-05) Smith, E.F.; Richardson, D.; Cox, R.F.; Follis, D.; Boren, Fred W.Sorghum grain is used extensively in fattening rations for beef cattle. Its protein content reportedly varies from 6 to 12%. Wide differences in protein content result from variety, nitrogen supply in the soil, geographic location, moisture during a given year, and yield per acre. Interest is increasing in the varying protein content of sorghum grain. The main question is whether the protein in sorghum grain can satisfy the entire ration protein for fattening cattle. Objective of this experiment was to determine the value of adding various amount of soybean oil meal to dry-rolled and steam-rolled sorghum grain fattening rations for yearling heifers.Item Open Access Dehydrated alfalfa vs. Vitamin A with and without Aureomycin to cattle rations using sorghum grain(Kansas Agricultural Experiment Station, 2011-05-05) Richardson, D.; Smith, E.F.; Koch, B.A.; Boren, Fred W.The animals’ in this test were used in a previous wintering test to study grain vs. forage type sorghum silage; dehydrated alfalfa as a source of Vitamin A vs. Vitamin A; and Vitamin A with and without Aureomycin. At the end of the test, cracked sorghum grain was added to the ration and the fattening phase was started. Animals that had received dehydrated alfalfa in the wintering phase continued to receive it during the fattening phase and likewise those that received Vitamin A continued to receive Vitamin A. The dehydrated alfalfa contained approximately 50 mgs. of carotene per pound. Assuming 400 I.U. of Vitamin A per milligram of carotene, one half pound of dehydrated alfalfa supplied the equivalent of 10,000 I.U. of Vitamin A; hence, the comparison of one half pound dehydrated alfalfa pellots as a source of Vitmain A with 10,000 I.U. of preformed Vitamin A. each source of Vitamin A was fed with and without Aureomycin. The ration ingredients and average daily consumption are shown in Table 1. Salt and a mixture of salt and dicalcium phosphate were fed free choice.Item Open Access The value of Chlortetracycline for steers on a wintering, grazing and fattening program(Kansas Agricultural Experiment Station, 2011-05-05) Smith, E.F.; Koch, B.A.; Richardson, D.; Boren, Fred W.Twenty good to choice Hereford steer calves from near Ft. Davis, Texas, were randomly divided into two lots. One group served as the control: the other was treated in a similar way except that each animal received 70 mgs. of chlortetracycline (aureomycin) daily.Item Open Access Corn, sorghum grain, wheat, rye, and barley each as a concentrate in complete pelleted rations compared with a standard nonpelleted sorghum grain and alfalfa hay ration for self-feeding fattening lambs(Kansas Agricultural Experiment Station, 2011-05-05) Hillman, M.; Richardson, D.; Cox, R.F.This test duplicates one last year, which was designed to study various grains in complete pelleted rations compared with a standard nonpelleted ration. Previous work has shown that a complete pelleted ration composed of 30 to 40 percent concentrate produced faster, more efficient lamb gains than a nonpelleted ration of the same composition.Item Open Access The effect of added calcium and phosphorus with and without added protein to the ration of steers on bluestem pasture(Kansas Agricultural Experiment Station, 2011-05-05) Drake, C.L.; Smith, E.F.; Tsien, W.S.; Follis, D.L.This experiment was designed to evaluate the desirability of supplementing bluestem pasture as indicated in the title. Forty Hereford steer calves were divided into four lots of 10 each and fed the following experimental rations per head daily: Lot 1. Two pounds of dehydrated molasses (a molasses product dried on soybean hulls) Lot 2. Two pounds of dehydrated molasses and 39.1 grams of dicalcium phosphate. Lot 3. One pound of dehydrated molasses and 1 pound of 41% corn gluten meal. Lot 4. One pound of dehydrated molasses and 1 pound of 41% corn gluten meal plus 29.6 grams of dicalcium phosphate.
