Item Open Access Fattening heifers for the summer or early fall market(Kansas Agricultural Experiment Station, 2012-01-30) Pickett, A.G.; Weber, A.L.The two preceding tests with heifer calves were conducted without the use of grass. Varying amounts of grain and protein supplements were fed with silage during the winter season and then a full feed of grain was used to finish these heifers for the summer or early fall market. Now that experimental pasture is available, plans are to develop a system of fattening heifers for the summer market or early fall market which uses grass to the fullest extent. Dry lot feeding will continue as a check.Item Open Access Effects of cattle grub treatment.(Kansas Agricultural Experiment Station, 2012-01-30) Bell, F.W.; Dean, G.A.Five heifers in each of four lots of 10 head each were treated with rotenone dust December 11, 1945. The other five heifers in each lot received no treatment for grubs. At the time of treatment a careful count was made of the number of grubs on each of the 10 heifers in each lot. Thus the trial furnishes data on 20 heifers treated for grubs and 20 which were not treated, with all factors of feeding and management being the same in each lot. Another check for evidence of any grubs which might not have been killed by the first treatment was made January 9, 1946. On this date all the heifers previously treated which showed any grubs not destroyed were dusted again with rotenone dust. Each lot of heifers was marketed when they averaged about 850 pounds in weight. Since the feeding trial was to determine the results of different quantities of grain fed to finish the cattle, the dates of marketing the four lots ranged from May 31, 1946 to July 30, 1946.Item Open Access The use of mustard seed oil meal as a protein supplement for fattening pigs in the dry lot.(Kansas Agricultural Experiment Station, 2012-01-30) Aubel, C.E.Protein supplements are essential to profitable pork production whether it be the maintenance of the breeding herd, growing the pigs, or fattening pigs for market. Previous tests at this station have shown the advantage and profit in feeding tankage and other protein supplements with corn or other grains when pigs are fed in the dry lot or on pasture. About a year ago the Department of Animal Husbandry was asked to conduct some experimental feeding tests with mustard seed oil meal. This meal was being produced in a Kansas seed oil extraction plant by expressing the oil from wild mustard seed. The seed had been shipped from northern wheat growing areas, where it had been separated from Spring wheat, which it contaminated very badly. There was a considerable potential supply of this seed and the meal or residue remaining from the oil extraction contained considerable protein, so it was thought that it might have considerable value as a protein supplement for livestock. Consequently the Department of Animal Husbandry became interested and carried on some feeding experiments.Item Open Access The comparative values of foxtail willet seed and shelled corn for fattening spring pigs on alfalfa pasture.(Kansas Agricultural Experiment Station, 2012-01-30) Aubel, C.E.In order to fatten pigs economically it is necessary to feed a large amount of concentrates in the form of grain and protein supplements. Corn is the grain usually employed. When the price of corn becomes very high in relation to other feeds, hog feeders look about for a substitute. In recent times corn has been high in price, and occasionally impossible to purchase. This was the situation a year ago when a purchase of Foxtail Millet seed was made to replace corn. With this seed on hand it was thought advisable to carryon a feeding trial to compare it with corn in efficiency, as the state might be in a position sometime to grow considerable millet. The information thus obtained would then be available and valuable to the swine feeder.Item Open Access Physical balance (proportion of concentrates to roughage) in lamb fattening rations.(Kansas Agricultural Experiment Station, 2012-01-30) Cox, R.F.In several years of experimental studies of physical balance as a factor in determining the value of lamb fattening rations, more than 2000 lambs have been fed, and a wide variety of feeds have been employed. The experimental rations have been made up of feeds ranging from high palatability and nutritive value, such as corn, cottonseed meal, and alfalfa hay, to combinations which have finitely lower nutritive value, particularly the roughages of matured grain varieties of sorghums.Item Open Access Factors influencing rate of gain, quantity of feed consumed and carcass grade(Kansas Agricultural Experiment Station, 2012-01-30) Bell, F.W.; Mackintosh, D.L.; Pickett, A.G.The two lots of heifer calves in this test were selected from 75 range bred heifer calves purchased last fall. The 75 heifers were a uniform group, all of which would be classed as good to choice feeder calves. The 10 heifers in Lot 1 of this test were selected as the least desirable, and the 10 heifers in ,Lot 2 as the most desirable of the 75 head. The sort was made on the evidences of probable gains and carcass grades as indicated by capacity for feed, chest room, bone, heads, muscling and general appearance.Item Open Access Influence of winter rations and gains on subsequent pasture gains.(Kansas Agricultural Experiment Station, 2012-01-30) Pickett, A.G.; Weber, A.D.Many authorities and successful beef cattle producers have held the belief that the safest long-time beef production system was one that kept the producer in business 12 months of the year. This, of course, means wintering, grazing and under certain conditions, feeding some grain. In the past we have not been in a position here at the college to work out details of the various systems of beef production since experiment grazing land was not available. March 1, 1947 we gained possession of 1,143 acres of bluestem grass which will be used to develop the best systems of beef cattle production. Other problems dealing with grass utilization will also be studied.Item Open Access The use of loose salt for fattening pigs on corn, tankage and alfalfa hay in the dry lot.(Kansas Agricultural Experiment Station, 2012-01-30) Aubel, C.E.The Department of Animal Husbandry has recently received a number of requests for information on the need of salt for fattening pigs when the ration was corn and tankage with alfalfa hay or pasture. The answer to these inquiries has always been that pigs did not need salt when they received tankage or some similar protein supplement of animal origin; but if most of the protein supplement was of plant origin as soybean meal, cottonseed meal, alfalfa meal, or linseed meal, salt was advisable.
