Item Open Access The comparative value of mustard seed oil meal and dehydrated brome grass meal in protein feed mixtures as a supplement to shelled corn for fattening fall pigs in the dry lot.(Kansas Agricultural Experiment Station, 2012-01-30) Aubel, C.E.Swine experiment I, page 43, reported the results of feeding mustard seed oil meal to fattening pigs on alfalfa pasture, when mixed with tankage and other protein supplements. Pigs were fed with protein supplement mixtures in which the mustard seed oil meal composed as much as 50 percent of the supplement. The results of feeding it in such large proportions were so satisfactory that it was desired to ascertain whether it were possible to increase further the amount of mustard seed meal in the mixture with tankage and still get good results. Consequently two lots of pigs were fed with an increased percentage of mustard seed oil meal. In addition last year in connection with some other studies there was produced at the Kansas Experiment Station some dehydrated brome grass meal. This meal had a protein content of about 20.9 percent. As there was no information at hand concerning the use and palatability of brome grass meal in swine feeding, it was thought advisable to compare it with dehydrated alfalfa meal.Item Open Access The use of loose salt for fattening pigs in the dry lot.(Kansas Agricultural Experiment Station, 2012-01-30) Aubel, C.E.At the Livestock Feeders' Day last year, data were presented on the use of loose salt in swine fattening rations when the pigs were self-fed free choice a ration of shelled corn, tankage, and alfalfa hay. It was shown that loose salt, self-fed to pigs provided no advantage in producing faster gains or in improving the efficiency of the rat ion. In the test reported on last year the entire protein supplement, aside from the alfalfa was of animal protein. Since present-day hog supplements are largely mixtures of plant and animal protein feeds, it was thought that information would be desirable on the influence of feeding salt when a supplement of such a composition was fed.Item Open Access Mustard seed oil meal as a protein supplement for fattening pigs on alfalfa pasture.(Kansas Agricultural Experiment Station, 2012-01-30) Aubel, C.E.Last year at the Livestock Feeders' Day, results of experiments were given on the use of mustard seed oil meal as a protein supplement for fattening pigs in the dry lot. The results showed that mustard seed oil meal was an excellent protein feed when mixed with tankage and other protein supplements and self fed free choice. Generally the gains were somewhat cheaper than where tankage alone was fed, but the gains were not quite so rapid. In the tests reported last year the mustard seed meal made up as much as 50 percent of the protein mixtures, in some of the lots. With mustard seed meal proving to be so satisfactory for dry lot feeding, it was thought desirable to obtain data on its efficiency in the pasture feeding of spring pigs.Item Open Access The relationship of physical balance to energy value and tissue formation in sheep(Kansas Agricultural Experiment Station, 2012-01-30) Cox, R.F.; Mackintosh, D.L.; Smith, E.F.; Hughes, J.S.Several years of physical balance studies with sheep rations have been completed. During the course of these years, more than 2500 lambs have been used in the experiments. A wide variety of feeds have been employed in these tests also. The feeds composing the experimental rations have varied widely in nutritive value and palatability. In spite of this fact, the results of these experiments have been in agreement with remarkable consistency. While many levels of physical balance have been studied, recent trials have been limited to proportions of concentrates to roughage ranging from extremes of 35 percent to 65 percent up to 55 percent to 45 percent.Item Open Access The effect of bicarbonate of soda in reducing digestive disorders and death losses in feeder lambs.(Kansas Agricultural Experiment Station, 2012-01-30) Cox, R.F.Among a number of means tested in an effort to minimize digestive disorders and death losses in lambs caused by “over-eating disease” baking soda appeared to be effective to some extent. At the Garden City Branch Agricultural Experiment Station, two lots of lambs recently were put on feed to check this. This experiment was completed in March and a detailed report of the results appears in Table III of the Sheep Investigations section of this bulletin.Item Open Access Effect of grinding on the nutritive value of grain sorghums for fattening steer calves.(Kansas Agricultural Experiment Station, 2012-01-30) Smith, E.F.Livestock feeders have often called attention to the large amount of sorghum grains passing through cattle when the whole grain is fed. Small hard grain, when not broken by chewing, seems to escape digestion altogether. The question, therefore, has arisen as to the best method of feeding grain sorghums for the most efficient utilization by fattening cattle.Item Open Access Fattening heifers for the summer or early fall market, 1947-48.(Kansas Agricultural Experiment Station, 2012-01-30) Pickett, A.G.; Smith, E.F.Eight lots of heifers are being used in the current test. All eight lots have been wintered on a daily ration of 20 pounds Atlas sorgo silage, full access to prairie hay in racks, and 8 protein supplement. Dehydrated brome grass and dehydrated alfalfa pellets and a combination of dehydrated brome grass and cottonseed meal were compared with the standard oil seed meals and with mustard seed meal. In addition to the above ration, lots 1 to 5 inclusive received 2 pounds ground shell corn.Item Open Access Factors influencing rate of gain, amount of feed consumed and carcass grade(Kansas Agricultural Experiment Station, 2012-01-30) Bell, F.W.; Mackintosh, D.L.; Pickett, A.G.This is the second trial to study the effect of differences which can be observed in feed calves classified as good to choice. The two lots in this trial were sorted from the 100 range-bred heifer calves purchased last November for feeding experiments at this station. This was a very uniform shipment of calves with no plain ones in the group. Sorting for the two lots of calves was made on apparent differences in capacity for feed, chest room, muscling, bone, and general appearance. The individual calves also were graded by using a standard feeder chart.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 in this trial were selected from 75 range-bred heifer calves purchased in November, 1946 for feeding tests at this station. These calves were a uniform group classified as good to choice feeder calves. The 10 calves in Lot 1 were selected as the probable poorer gainers, and the 10 calves in Lot 2 as the probable better gainers. The sort was made on the evidences of probable gains as indicated by body capacity, chest room, muscling, bone and general appearance. Sorting on the basis of these characteristics resulted in heaver average initial weight of the calves in Lot 2. The calves also were graded individually by using a standard feeder chart. Lot 1 graded average good, and Lot 2 low choice.Item Open Access Fattening heifers for the summer or early fall market.(Kansas Agricultural Experiment Station, 2012-01-30) Pickett, A.G.The two preceding tests with heifer calves were conducted without the use of grass. Varying amounts of grain and protein supplement were fed with silage during the winter season and then a full feed of grain was used to finish the.se heifers for the summer or early fall market. With experimental pastures available, grass is being used to the fullest extent in developing a system of deferred feeding for fattening heifers.Item Open Access Influence of winter rations and gains on subsequent pasture gains.(Kansas Agricultural Experiment Station, 2012-01-30) Pickett, A.G.; Smith, E.F.This test began with good to choice steer calves. The purpose is to use bluestem grass to the best advantage in producing beef. Two of the lots were fed out at the close of the first season's: grazing And the other three lots have been wintered and will be grazed a second season.
