Yeast in Growing-=Finishing Rations with Two Protein Level Comparisons

In a previous report ( A.H. Mimeo Series 62-7 ) yeast culture was evaluated as an additive to good growing-finishing swine rations. Yeast did not have an effect on daily gain; however, feed efficiency was improved 6 per cent when 2 per cent yeast was included in the ration. If yeast has an enzyme action and digestion value, the yeast should improve a ration that is formulated with less crude protein than normally provided. An experiment was designed to compare levels of yeast and two levels of crude protein

Supplemental L-Lysine in Milo Rations for Growing-Finishing Swine

Nutritionists are interested in L-lysine addition to swine rations because; (1) L-lysine is an essential amino acid in the diet for best growth, (2) cereal grains and soybean meal are comparatively low in lysine, (3) proper balance of amino acids in the ration is important for good growth and feed conversion. Some experimental results suggest lysine is not a replacement for protein in the ration but should be added to rations already adequate in crude protein, (4) L-lysine can now be produced by a fermentation process which has lowered the cost

Portable Feeding Stalls

Feeding stalls aid a restricted feeding program. Feeding stalls are used to provide a place for sows to consume their feed with a minimum of interference from other animals. Many stall plans appear to provide an entire four-sided pen for each sow. These stalls may be more elaborate and costly than necessary. A simple stall made of a small partition is probably adequate to keep the sows apart. The stalls in the photos illustrate four different types

Wet Versus Dry Methods of Feeding Growing Finishing Swine Rations

Swine are fed many different types of rations and there are many methods of feeding swine throughout the world. Apparently there is no one best way to feed swine. Wet complete mixed rations are limited-fed to some extent in other countries, Reasons for this type of feeding are available labor, limited feed supply, and feeding to produce a particular type of hog for the market. The most widely accepter method in the United States is self-feeding either complete mixed rations or free-choice corn and protein supplement. Wet rations are not generally fed in this counti because labor is high priced or not available, equipment is not available to automatically feed wet rations, and there is no particular market price advantage. Several questions have been asked in regard to wet feeding modern swine rations. The trend is toward automation and feeding hogs in confinement which offers more flexibility in the method of feeding. If automatic equipment were available to feed the wet rations with little or no increase in labor, would more swine producers prefer this method over their present setup? What is the performance of pigs fed the wet rations? If pig performance is satisfactory, can automatic equipment be developed and economically used for this type of feeding? Research Information is needed before these questions can be properly answered. This experiment was designed to study the performance of the pigs fed wet or dry rations

Yeast in Growing-Finishing Swine Rations

The culture used in the following experiment was stated by the company to be live cell yeast grown on cereals and dormantized at low temperatures so as not to kill or injure the live cells or destroy any of their natural values. The finished yeast culture was a dry stabilized meal that readily blended with other feed ingredients in a complete mixed ration. The yeast culture was added for possible digestive enzyme action and additional source of B vitamins. Enzymes may be helpful in the breakdown and utilization of complex carbohydrates, fat and protein. The purpose of this experiment was to evaluate the yeast as an additive to swine rations

More Testing Needed

The purebred swine business, like farming or any other business, must be progressive, sensitive to change, and always looking for new and better ways to grow and prosper. The ideas presented in this article are not especially new, in fact, good swine producers have already put most of these ideas into practice. However, some breeders still use production programs and salesmanship of ten years ago and now have a second rate program. The decision must be made—shall the program remain second rate or can some newer information, particularly that regarding accepted testing programs be put into use

Free-Choice Feeding with Combinations of L-lysine, Methionine and Fat in Protein Supplement

The trend in feeding growing-finishing swine seems to be toward feeding a complete mixed ration. However, many swine producers prefer to feed shelled corn and protein supplement free-choice. There are advantages and disadvantages to both methods and either method can be used for profitable production. Recent major emphasis on research has been on complete rations. More research is needed on additives in protein supplements which are formulated for free-choice feeding. The following experiment was designed to compare complete mixed rations and free-choice rations with combinations of L-lysine, methionine and yellow grease

Proper Location of Feeder and Waterer - Outside Versus Inside Comparisions

Has planning been adequate in regard to the best location of the feeder and waterer within the growing-finishing pen? Perhaps there is adequate planning, but most of the emphasis is placed on the convenience for the manager. Good managers know the performance of pigs, especially young pigs, is sub-optimal when the feeders and waterers are improperly located. Cold or hot temperature and other adverse weather conditions have an influence on pig performance. We have observed that our experimental pigs are extremely reluctant to go outside to eat or drink after a sudden drop in temperature during the winter. Some units for confinement rearing of pigs have been designed with the feeders outside (usually along the end of the pen for the convenience of filling), while other units have been built with the feeder inside. Could this difference in location have any effect upon the growth and feed efficiency of the pigs? The purpose of this experiment was to determine what effect location of feeders and waterers had upon pig performance

Effect of Iron, Lysine, Vitamins and an Antibiotic in Water on Growing-Finishing Swine

Several studies have been conducted at this station with nutrients or additives in the water, but studies have not been made on treatments with several nutrients and additives in combination. If water is used as a means of feeding nutrients, then it is reasonable that several nutrients could be fed in the water. The following experiment was conducted as a preliminary investigation on the effects of several nutrients and an antibiotic in water

Diets for Early Weaned Pigs

Several expensive ingredients are normally included in baby pig rations for optimum performance of the pigs. Some of these ingredients are rolled (hulled ) oats, dried skimmilk, dried whey, sugar and high levels of antibiotics. They are added to improve palatability, increase digestibility of the ration and protect the pigs from scours and harmful microflora. Most of the rations are highly fortified with vitamins. All of these materials, plus pelleting, make the ration rather expensive. Studies at the Minnesota station have shown that pigs do well on the sophisticated rations, but the response over a more simple ration is not always enough to pay the cost of these more expensive ingredients. An experiment was initiated here to study diets for young pigs. The study is expected to last several years and cover several aspects of the nutrition for young pigs. The first trial was designed to compare com-soybean meal-type rations with a ration containing some rolled oats, dried skimmilk and sugar as well as some corn, soybean meal, minerals, vitamins and an antibiotic
