The Soft Corn Problem

Making the most of the soft com is a problem that confronts tho corn growers of Iowa. Many of our people have the idea that soft corn is practically worthless but that is very far from tho truth, indeed

Is the Appetite of Swine a Reliable Indication of Physiological Needs?

The pig is farrowed with a fairly definite set of specifications for development all wrapped up in their mystery in a two to three pound bundle of throbbing, active stuff. And yet before the pig sought the outer life apart from the womb of his dam, these specifications were enclosed in the minutest bit of protoplasm, the impregnate ovum resulting from the union of two germ cells, one from the male and the other from the female

Forage Crops Save Protein Supplements

Forage crops are essential in good and economical summer rations for growing and fattening swine. They provide a way to cut down the cost of gains, inasmuch as they cut down on the requirement of meat meal tankage and other desirable protein supplements which are usually high in price. At the same time they enlarge opportunities for the quicker, more profitable raising of better and healthier pigs

Corn Oil Cake Meal for Growing and Fattening Pigs

Corn oil cake meal is really a residue of the germs of corn grain which remains after most of the oil is extracted therefrom. The particular corn oil cake meal which we used in our test is a by-product from the manufacture of glucose. These four main products are made from the corn grain: Glucose, corn oil, gluten feed, and corn oil cake meal. It is with the latter that we are to deal

Corn supplements and substitutes for fattening lambs

This test was planned to determine the advisability of adding a protein supplement to a basal ration of shelled com, corn silage, alfalfa hay and block salt for fattening range lambs; to compare the relative value of linseed oil meal, velvet bean feed meal and peanut meal as protein supplements added to the same basal ration; and to note the practicability of replacing the shelled corn in the basal ration with corn gluten feed, a corn by-product. Linseed oil meal is a well established and popular supplement to corn widely used for lamb feeding. Velvet bean feed meal and peanut meal are comparatively new supplements, neither being fed to any great extent to live stock in the corn belt. However, both velvet beans and peanuts have been used in the southern states with fairly good results

Iodine, a Factor in Feeding Young Growing Swine

Iodine is now generally believed to be absolutely essential for the proper growth and development of the mammalian organism, and its use in animal feeding is becoming more and more general, particularly in goitrous regions

The acid-base balance in animal nutrition, I. The effect of certain organic and mineral acids on the growth, well-being and reproduction of swine, II. Metabolism studies on the effect of certain organic and mineral acids on swine

The question of the balance between acid and base-forming mineral elements in foodstuffs has figured more or less prominently in discussions of rations for both man and animals during the last decade. Based principally on the work of Forbes, Sherman and Gettler , and Castle, there has developed a considerable tendency to emphasize the necessity for a balance between potential acid and base in the mineral constituents of rations. In this preliminary discussion human dietary standards will figure, as well as rations for animals, but in reporting our conclusions we shall avoid the too common error of applying data obtained with one species to other species

Baby beef production

Methods employed and results secured in baby beef production work at Walnut Ridge Stock Farm, E. M . Cassady and Son, proprietors, Whiting, Iowa, with the Animal Husbandry, Section of the Iowa Agricultural Experiment Station co-operating. The ranch cattle owner has reduced the selling age.of his steers from four and five years to two-year-olds, yearlings, and to a relatively large extent, calves, depending upon conditions of climate\u27 and feed, and demands from feeders of the corn belt. The corn belt farmer contends with high priced land, feed and labor. Outside of the field of purebred beef cattle production his operations are very largely limited to the feeding of cattle purchased from the range, usually thru the central market. Some farmers have been raising their own cattle for feeding purposes. They find the conditions of high priced land, feed, arid labor favorable in some respects to baby beef production

Feeding the Brood Sow

The brood sows represent in a large measure the backbone or the swine herd, hence their correct nutrition and handling are of dollars and cents Importance

Successful Swine Rations for the Corn Belt

Just how much or protein and mineral supplements should be fed with corn to swine or various sizes, ages, and classes is the big question which this circular considers. Up-to-date practice is reflected in the rations presented; furthermore, these rations have been tested In actual practical feeding trials under the experimental supervision of the animal husbandry section of the Iowa Agricultural Experiment station
