Item Open Access The effect of level of dietary iron on pork muscle characteristics(Kansas Agricultural Experiment Station, 2011-05-06) Kropf, Donald H.; Mackintosh, D.L.; Hall, J.L.; Harrison, D.L.; Hunsader, M.; Ahlschwede, G.A.Muscle color is an important factor affecting shoppers’ choice of pre-packaged meats from self-service display cases. The effect of several levels of dietary iron and of two levels of a chelating agent on pork muscle characteristics was studied.Item Open Access The relationship of certain physical and chemical factors to cooking and sensory evaluations of beef(Kansas Agricultural Experiment Station, 2011-05-06) Moe, D.R.; Kropf, Donald H.; Mackintosh, D.L.; Harrison, D.L.; Anderson, L.A group of 32 wholesale beef ribs, from cattle of known history, ranging in grade from high standard to high good, were used. A longissmus dorsi (rib eye muscle) sample was removed at the 12th rib and used to obtain color, pH, water-holding capacity and cooking data. Another longissimus dorsi sample from the 9-10-11th rib cut was chemically analyzed for protein, moisture and ether extract and buttons (spinous process-distal portion) were removed for penetrometer readings and calcium determinations. The 6-7-8th rib section was roasted, and cooking data (cooking time and losses), sensory evaluations by a subjective panel and objective measures were obtained by personnel of the Department of Foods and Nutrition. Correlation coefficients were calculated between various factors.Item Open Access Different methods of managing bluestem pasture(Kansas Agricultural Experiment Station, 2011-05-06) Smith, E.F.; Anderson, K.L.; 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 performances, 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 14 years is included.Item Open Access The value of dicalcium phosphate, Vitamin A and grinding corn for calves fed prairie hay(Kansas Agricultural Experiment Station, 2011-05-06) Smith, E.F.; Richardson, D.; Curtis, R.G.; Dunn, L.The 60 good-to-choice grade Hereford calves used in this test came from near Fort Davis, Texas. They were assigned 10 to a lot on the basis of weight. All lots received all the prairie hay they would consume, about four pounds of corn each daily, and 1.25 pounds of soybean meal; where Vitamin A (15,000 I.U. daily) and dicalcium phosphate (0.1 pound per head daily) were fed they were mixed with the soybean meal. In the lots fed ground corn it was ground medium coarse or between fine and coarse ground: the modulus of fineness was 4.34.Item Open Access Influence of breeding and length of feeding period on carcass characteristics and palatability of beef(Kansas Agricultural Experiment Station, 2011-05-06) Mackintosh, D.L.; Kropf, Donald H.; Harrison, D.L.; Moore, E.R.; Ahlschwede, G.Sixty-four steer calves owned by Martin K. Eby and sired by the same bull were selected randomly from the 1962 fall calf crop. The calves were randomly selected and sorted into eight groups and placed in the feedlot. The first group was shipped to Kansas City for slaughter. Fifty-six days later Lot 2 was shipped and each 28 days thereafter eight steers were slaughtered for dressing and carcass data.Item Open Access Level of protein for heifer calves wintered on bluestem pasture(Kansas Agricultural Experiment Station, 2011-05-06) DeGeer, C.V.; Smith, E.F.; Richardson, D.; Good, D.L.The 65 heifers used in this study were good-to-choice Herefords purchased near Fort Davis, Texas, assigned to treatments on a random-weight basis. The heifers were rotated between pastures so any differences due to pastures were minimized. Dicalcium phosphate was fed to standardize phosphorus intake between groups.Item Open Access Nutritive value of forages as affected by soil and climatic differences(Kansas Agricultural Experiment Station, 2011-05-06) Richardson, D.; Banbury, Evans E.; Erhart, A.B.; Williams, G.; Russ, Oliver G.; Harbers, L.H.; Loper, D.C.; Cox, R.F.This is a progress report on the second test to determine whether there is a differences in the performance of beef steers due to location, soil, climate, rainfall and/or feed produced in four area of Kansas: Colby, Garden City, Manhattan, and Mound Valley. Forty-eight Hereford steer calves averaging 454 pounds each were divided into four groups of 12. One lot was assigned to each location. Sorghum silage from the same variety (FSIA) and second cutting of alfalfa plus plain salt were used in the wintering phase. Feedstuff analyses are show in Table 36, and results of the wintering phase, in Table 35. Silage has been removed from the ration and sorghum grain added. The animals will be fattened for slaughter.Item Open Access The value of wheat shorts in coarse and fine ground concentrate mixtures for fattening heifers(Kansas Agricultural Experiment Station, 2011-05-06) Smith, E.F.; Richardson, D.; Kramer, J.E.Twenty-four yearling Hereford heifers with a USDA Feeder Grade of about High Good were divided on the basis of prior treatment and on a random-weight basis into four groups of six heifers each. The experimental diet is listed in Table 53. Two lots of six each received wheat shorts to increase the protein content of the corn based ration to 10.5 percent protein, two lots received soybean oil meal in their mixture to raise the protein content to the same level. One lot fed wheat shorts and one lot fed soybean meal received their concentrate mixture fine ground: in the other wheat shorts and soybean meal lots, the mixture was fed in a medium-coarse ground form. The cattle were fed twice daily for about 60 days and then self-fed the latter part of the trial. No roughage was fed about the last 30 days of the trial.Item Open Access The effects of adding protein to dry-rolled sorghum grain fattening rations(Kansas Agricultural Experiment Station, 2011-05-05) DeGeer, C.V.; Smith, E.F.; Richardson, D.; Cox, R.F.; Boren, Fred W.Previous work indicated sorghum grain fattening rations supplemented with 0.5 pound per head daily of soybean oil meal produced less efficient gains but carcasses about equal to those from heifers fed 1 pound of soybean oil meal per head daily. With each increase of 0.5 pound of protein (0.5 lb.-1.5 lbs.) came an increase in average daily gain and an increase in feed efficiency.Item Open Access The value of supplemental copper and cobalt for steers on fattening rations(Kansas Agricultural Experiment Station, 2011-05-05) Gnadt, K.L.; Smith, E.F.; Richardson, D.; Kramer, J.E.; Dunn, L.; Boren, Fred W.Cobalt is one of the more recent minerals discovered to be essential to ruminants. It is necessary for the synthesis of Vitamin B 12 in the rumen. Copper is necessary for hemoglobin formation, along with iron. Corn is considerably lower in copper and cobalt than sorghum grains, according to the National Research Council. Its requirement tables for beef cattle show that 2 to 4 mgs. of copper and .03 to .05 mg. of cobalt are required per pound of feed.Item Open Access Dicalcium phosphate and Vitamin A for calves on winter bluestem pasture, 1962-63 (Project 253-1)(Kansas Agricultural Experiment Station, 2011-05-04) Smith, E.F.; Richardson, D.; DeGeer, C.V.; Boren, Fred W.The 40 steer calves, 10 per lot, used in this experiment were good-to-choice Herefords from near Fort Davis, Texas, assigned on a random-weight basis to their treatments. They were pastured together in a 190-acre bluestem pasture during the winter, penned three times weekly, divided into treatment groups and fed the experimental diets show in Table 40. The lots receiving dicalcium phosphate (0.1 pound per steer daily) and Vitamin A (10,000 I.U. daily) received it mixed with soybean meal.Item Open Access Dicalcium phosphate and Vitamin A for calves on winter bluestem pasture (Project 253-2)(Kansas Agricultural Experiment Station, 2011-05-04) Theurer, L.J.; Smith, E.F.; Richardson, D.; Boren, Fred W.The 40 heifer calves,10 per lot, used in this experiment were good-to-choice Herefords from near Fort Davis, Texas, assigned on a random weight basis to their treatments. They were pastured together in a 190-acre bluestem pasture, penned three times weekly, divided into treatment groups, and fed experimental rations shown in Table 41. Dicalcium phosphate (0.1 pound per heifer daily) and Vitamin A (10,000 I.U. daily), when fed, was mixed with soybean meal.Item Open Access Improving beef cattle through breeding methods(Kansas Agricultural Experiment Station, 2011-05-04) Smith, W.H.; Wheat, J.D.; Spies, H.G.The purebred Shorthorn beef cattle breeding project was continued during 1963 without modification. Inbreeding was continued in the two separate lines, which have remained closed to outside breeding since the study was initiated in 1949. The inbreeding plan has been basically to continue successive generations of half-sibbing in both lines. The Wernacre Premier line is in its fifth generation and the Mercury line, its fourth generations of inbreeding.Item Open Access The effects of feeding different levels of dicalcium phosphate to heifers on bluestem pasture(Kansas Agricultural Experiment Station, 2011-05-04) Drake, C.L.; Smith, E.F.; Spies, H.G.; Richardson, D.; Good, D.L.This trial was designed to study effects of low to high levels of calcium and phopphorus supplements on heifers grazing bluestem pasture. February 18, 1961, 40 Hereford heifer calves, weighing about 400 pounds each, were randomly divided into four groups and turned into a 140-acre pasture. Each morning the heifers were gathered, divided into four lots and fed the experimental rations shown in Table 49. The chemical analysis is presented in Table 48.Item Open Access Level of Vitamin A in beef steer rations: Wintering phase(Kansas Agricultural Experiment Station, 2011-05-04) Richardson, D.; Smith, E.F.; Dunn, L.; Harbers, L.H.Sixty Hereford steer calves were divided into six equal lots. Sorghum silage ad lib. And 1 pound of soybean oil meal per head daily were fed to all lots. Half of the animals (Lots 7, 8, and 9) received 8 pounds of sorghum grain pr head daily; the other half (Lots 10, 11, and 12), 4 pounds per head daily. This phase of the test was to measure performance on two levels of grain and prepare the animals for the fattening phase. At the beginning of the fattening phase, the animals were reallotted to six lots of 10 with five animals from the 8-pound level of grain and five from the 4-pound level.Item Open Access Nutritive value of forages as affected by soil and climatic differences(Kansas Agricultural Experiment Station, 2011-05-04) Richardson, D.; Banbury, Evans E.; Erhart, A.B.; Davidson, F.R.; Williams, G.; Smith, E.F.; Loper, D.C.; Harbers, L.H.; Cox, R.F.It is generally thought that performance of cattle may differ in various parts of the state due to location, soil, climate, rainfall and/or feed produced. This project is an attempt to determine whether such differences exist and, if so, to measure them.Item Open Access The effect of partial wilting on the feeding value of forage sorghum silage(Kansas Agricultural Experiment Station, 2011-05-04) Smith, E.F.; Ward, G.M.; Richardson, D.; Dunn, L.; Boren, Fred W.The object of this experiment was to evaluate forage sorghum (cut at the same physiological stage of maturity) ensiled with varying moisture contents. All forage was cut during two days but ensiled at three different times: immediately after cutting: after drying in the field about 24 hours; and after drying in the field about 48 hours.Item Open Access Slotted floors for swine(Kansas Agricultural Experiment Station, 2011-05-04) Koch, B.A.Slotted floors in all phases of swine production are being widely investigated. Confining pigs on a slotted floor is not a new idea. However, we need to know more about how best to use slotted floors.Item Open Access Cane molasses in rations of growing beef calves. The value of winter shelter for feedlot calves(Kansas Agricultural Experiment Station, 2011-05-04) Smith, E.F.; Richardson, D.; Deyoe, C.W.; Curtis, R.G.; Boren, Fred W.Choice grade Hereford steer calves in this test came from near Alden, Kansas, and were assigned to treatments on a random-weight basis. All lots received the same experimental diet except 10 percent molasses was substituted for grain in the self-fed mixture for two lots. Small adjustments were made to equalize protein and energy intake between molasses and no-molasses lots. The composition of the roughage-concentrate mixture is listed in Table 52; it consisted primarily of ground rice hulls, ground sorghum grain, additives and other nutrients, including additional protein.Item Open Access The effect of processing pork carcasses prior to rigor mortis upon muscle and fat quality(Kansas Agricultural Experiment Station, 2011-05-04) Weiner, P.D.; Kropf, Donald H.; Mackintosh, D.L.; Koch, B.A.The effect of processing pork carcasses before rigor mortis was studied in 21 market-weight swine. The left side of each carcass served as a control and was chilled for 48 hours at 32-36 F before being cut and processed by regular methods. The right sides (treated) were cut and processed within one hour of bleeding.
