Will Porcine Somatotropin (Pst) Lower Pork Quality? (1989), Melvin C. Hunt, Patter G. Whipple-Van, R D. Klemm, B R. Schricker, Robert D. Goodband, Jim L. Nelssen, Robert H. Hines, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

The types and diameters of muscle fibers from 30 barrows that had received daily injections of porcine somatotropin (pST) or a placebo and were fed dietary lysine at .6, .8, 1.0 or 1.2% were determined. Fiber data indicated that pST slightly increases the anaerobic metabolic potential of longissimus muscle. The higher levels of lysine caused enlargement of muscle cells. Earlier research has shown that this type of muscle biochemistry contributes to development of PSE muscle. Thus, use of pST in certain strains of pigs may lead to reductions in muscle quality.; Swine Day, Manhattan, KS, November 16, 1989

Influence Of Milk Levels Of Beef Cows On Returns: A Simulation Approach, R.R. Schalles, K.O. Zoellner, L.S. Clarke Jan 1989

Influence Of Milk Levels Of Beef Cows On Returns: A Simulation Approach, R.R. Schalles, K.O. Zoellner, L.S. Clarke

Kansas Agricultural Experiment Station Research Reports

Results of four simulated production systems indicated that high levels of milk produced calves that were heavier at weaning, primarily because of an increase in body fat. High levels of milk production, however, were a disadvantage when calves went directly to the feedlot. With slow-growing calves, the fat either had to be depleted postweaning, or the calves had to be slaughtered at less-than-desirable weights in order to maintain desirable carcass fat. High milk intake is more tolerable for calves with fast growth rates, whereas low milk intake is a an economic necessity for calves with slow growth rates. The moderate …

Kansas Agricultural Experiment Station Research Reports

Interseeded grain sorghum and soybeans have been evaluated as a silage crop over a 3year period. In the first 2 years, maximum dry matter (DM) yields occurred at the late-dough stage of the grain sorghum, and interseeded silages had higher crude protein (CP) and acid detergent fiber contents than non-interseeded late-dough stage, grain sorghum control silages. In year 2, seeding grain sorghum and soybeans in alternating IS-inch rows increased DM yield, CP content, and the proportion of soybean plants in the mixture compared to drilled (6-inch spacing) interseeding. Digestibilities of most nutrients were similar in all silages; however, cattle fed …

Effect Of Foraform® On Fermentation Of Alfalfa, Corn, And Forage Sorghum Silages, K.K. Bolsen, A. Laytimi, A.D. Drysdale

Kansas Agricultural Experiment Station Research Reports

Foraform® was evaluated in four trials using alfalfa, corn, and two forage sorghums harvested in 1987 and ensiled in PVC laboratory silos. There was a dramatic crop by Foraform interaction, with Foraform delaying and restricting the fermentations, as expected, in alfalfa and corn. In both forage sorghum hybrids, although the ensiling process was delayed about 24 hours by the Foraform treatment, end-product silages had lower pH values and equal or higher lactic acid levels than untreated silages. Foraform was effective at both 60 to 90 F temperatures in alfalfa, with treated silages having lower lactic and acetic acids, ethanol, and …

Improved Pork Products For The 1990'S (1989), Donald H. Kropf Jan 1989

Improved Pork Products For The 1990'S (1989), Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

The word "improved" in a commercial sense means "altered product characteristics to meet the consumers' real and perceived needs." The pork industry in the 90's must progress toward offering products designed to meet consumer demands instead of saying "this is what we are producing and you'd better buy it." For the pork producer, "improved" means those products that will. increase pork sales. We must realize that the primary nutritional contributions of pork to human diets will be protein and vitamins, especially B-vitamins. Perhaps we should emphasize these more in our advertising, but good flavor, low fat, low salt, and convenience …
