New Pork Industry Problems: Pss And Pse, Dan H. Gee
New Pork Industry Problems: Pss And Pse, Dan H. Gee
South Dakota Swine Field Day Proceedings and Research Reports, 1971
Over the past decade the swine producer has made tremendous strides in producing leaner and more heavily muscled hogs which yield a higher proportion of their carcass weight in lean edible portion. The modern pig has excelled his ancestry in total performance, growth, feed efficiency and muscle producing ability. Because of the advances made in nutrition, breeding, and management, the meat type pig of today is more efficient than ever be fore in conversion of feed protein to muscle protein. In addition, the environment under which many pigs are raised has been changed from the customary pasture and dirt lot …

Effect Of Dietary Protein Level On Growth And Carcass Characteristics Of Growing-Finishing Swine Fed To Heavy Weights, Keith E. Gilster, Richard C. Wahlstrom
Effect Of Dietary Protein Level On Growth And Carcass Characteristics Of Growing-Finishing Swine Fed To Heavy Weights, Keith E. Gilster, Richard C. Wahlstrom
South Dakota Swine Field Day Proceedings and Research Reports, 1971
In a previous experiment reported in A.S. Series 71-38, it was found that for growing pigs optimum gain, feed efficiency and carcass quality (meatiness) occurred at different dietary protein levels. It also appeared that the dietary protein level fed during the period of 170 to 250 lb. affected carcass development more than did dietary protein during the early growing phase. Therefore , this experiment was conducted to further study the effect of high and low dietary protein levels for pigs during three growth periods, 50 to 100 lb., 100 to 170 lb., and 170 to 250 lb.

South Dakota Swine Field Day Proceedings and Research Reports, 1971
Antibiotics have been used in swine feeds to improve growth and feed efficiency for approximately 20 years. It was the purpose of this experiment to reevaluate the effectiveness of aureomycin and to determine if a difference in the response to the antibiotic could be obtained if pigs were confined were confined on concrete or in dirt dry lots.
Copper, Zinc And Vitamin E Supplementation In Diets Of Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal
Copper, Zinc And Vitamin E Supplementation In Diets Of Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal
South Dakota Swine Field Day Proceedings and Research Reports, 1971
Pigs gain at a somewhat faster rate when diets are supplemented with copper at a level of 250 parts per million (ppm). Other minerals appear to interact with copper in the metabolism of the pig. It has been observed that zinc supplied in the diet with copper decreased the amount of copper stored in the liver. One of the objectives of this study was to obtain further information on the value of copper in swine diets and to determine the effect of a high level of zinc on liver copper storage. Another objective of this experiment was to study the …
Opaque-2 Corn In A Free-Choice Feeding System For Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal
Opaque-2 Corn In A Free-Choice Feeding System For Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal
South Dakota Swine Field Day Proceedings and Research Reports, 1971
Experiments conducted during the past few years have shown opaque-2 corn to have a higher nutritional value than normal corn. It is known that a higher content of the essential amino acid lysine is one of the reasons for the increased value of opaque-2 corn when fed to swine. Certain other essential amino acids are also present in higher amounts than in normal corn. It was reported at the corn could be fed free-choice to growing swine. The experiment reported herein was conducted to obtain further information on feed consumption and performance of growing-finishing pigs fed opaque-2 or normal corn …

Levels Of Diethylstilbestrol And Types Of Protein Supplements In Ground Ear Corn Diets For Finishing Cattle, L. B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1971
Results of numerous experiments have shown that diethylstilbestrol at 10 mg. daily in the feed of implanted at 30 to 36 mg. improves weight gains and feed efficiency of feedlot cattle. More recently it has been reported that feeding more than 10 mg. daily to heavier cattle results in further stimulation of weight gains and feed efficiency. Feeding of 20 mg. per head daily of diethylstilbestrol is now cleared for feedlot cattle above 750 lb.
Can Beef Quality Be Evaluated?, W. J. Costello, R. J. Berns
Can Beef Quality Be Evaluated?, W. J. Costello, R. J. Berns
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1971
Beef quality is important to the consumer. She wants to serve tender, juicy, tasty beef to her family each time she serves it. If she can consistently serve quality beef, she will serve beef frequently. If she finds that she cannot consistently serve quality beef cuts, she will serve something else. For that reason, beef quality becomes important to every one along the production line between the brood cow and the consumer.

Relative Position Of Farmer-Feeders In The Increasingly Competitive Cattle Feeding Business, D. G. Cox
Relative Position Of Farmer-Feeders In The Increasingly Competitive Cattle Feeding Business, D. G. Cox
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1971
Farmer-feeders can potentially compete with anyone in the cattle feeding business. They have traditionally had many built-in advantages. By feeding the cattle on the farm where the grain and roughage are grown, drying, handling, shrinkage and transportation costs are reduced, and returns can be increased per acre by being able to market roughages and silages through cattle. In addition, there are fewer people obtaining a profit out of both the cattle and the feed when cattle are fed at the source of the feed. Another plus factor that will become increasingly important is that pollution is not as big a …

Complying With Feed Additive And Drug Withdrawl Periods, D. G. Fox, J. H. Bailey
Complying With Feed Additive And Drug Withdrawl Periods, D. G. Fox, J. H. Bailey
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1971
Most drugs are accumulated in excretory organs such as the kidneys and liver , and they are found in higher levels for a longer time in these organs than in other tissue. Due to a continuous excretion of the drugs from these organs, tissue levels are usually rapidly reduced after the drug is no longer fed or injected. The rate of excretion of a drug and its end products from animal tissues must be established before it can be considered for approval by the Food and Drug Administration. Then withdrawal periods that are sufficiently long enough to permit complete or …
