Ten-Year Summary Of K.S.I.A. Swine Testing Station Data, Robert H. Hines Jan 1969

Ten-Year Summary Of K.S.I.A. Swine Testing Station Data, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Swine testing stations "performance prove" breeding lines for genetic progress in the swine industry. The phenotype of a boar is a combination of his genetic ability and environment (nutrition, health, and etc.). Thus by using central test stations where all pigs are housed in similar pens and fed the same rations, the effect of environment is reduced so the genetic ability is more accurately appraised. The Kansas Swine Testing Station first tested hogs for Kansas Breeders the fall of 1958. Since then about 100 breeders have participated in the test station.; Swine Day, Manhattan, KS, September 25, 1969


Ddvp (Shell Dichlorvos) For Pregnant Sows (1969), B A. Koch, Robert H. Hines Jan 1969

Ddvp (Shell Dichlorvos) For Pregnant Sows (1969), B A. Koch, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Most recent laboratory and research station reports have indicated that 2,2 - dichlorovinyl dimethyl phosphate (DDVP) (Shell Dichlorvos) fed at low levels to pregnant sows in late gestation favorably affects newborn pigs. A field study we reported last year showed no favorable effect among over 200 litters. More than 600 barrows were checked at slaughter and no difference was detected in slaughter age between pigs from treated or untreated sows. Trials reported here involve sows and gilts in the K-State research swine herd. Trial 1 was those farrowing in March; trial 2, those farrowing in May.; Swine Day, Manhattan, KS, …


Growing-Finishing Rations Supplemented With Zinc-Proteinate (1968), B A. Koch, Donald H. Kropf, Robert H. Hines Jan 1968

Growing-Finishing Rations Supplemented With Zinc-Proteinate (1968), B A. Koch, Donald H. Kropf, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

The need for zinc in swine rations has been firmly established. Likewise the inter-relationships between dietary zinc and other minerals, especially calcium, have been well authenticated. However, there are still many unanswered questions concerning zinc and its place in the swine diet.; Swine Day, Manhattan, KS, September 26, 1968


Heat-Extruded Sorghum Grain For Growing-Finishing Swine (1968), G L. Cowman, C W. Deyoe, B A. Koch, H B. Pfost, Robert H. Hines Jan 1968

Heat-Extruded Sorghum Grain For Growing-Finishing Swine (1968), G L. Cowman, C W. Deyoe, B A. Koch, H B. Pfost, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

This paper is a progress report of a research project initiated this past year designed to study the effects of heat and pressure processing of sorghum grain on the performance of swine. The theoretical reasoning behind this approach was to increase the utilization of sorghum grain by chemical and/or physical starch damage with the application of certain degrees of heat and pressure during processing. The starch granules, which contain complex forms of chemically stored" energy, must be broken-up and reduced into simple units of glucose in the digestive tract of the pig before absorption can occur.; Swine Day, Manhattan, KS, …


Effects Of Varying Sorghum Grain Soybean Meal Ratios And Added Methionine On Swine Gains, Feed Efficiency And Carcass Composition And Quality (1968), Donald H. Kropf, L H. Kasten, B A. Koch, Robert H. Hines Jan 1968

Effects Of Varying Sorghum Grain Soybean Meal Ratios And Added Methionine On Swine Gains, Feed Efficiency And Carcass Composition And Quality (1968), Donald H. Kropf, L H. Kasten, B A. Koch, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Limited work is available on proper protein levels in swine rations when sorghum grain is a major ration component. Remarkable improvement has been made in gaining ability, feed coversion and muscling in swine. Because of continued improvements in these characteristics due to breeding and selection, we need to periodically re-evaluate the requirements for protein and amino acid levels in swine rations. A deterioration in muscle quality' (color, firmness and marbling) seems to be associated with production of lean pork. This prompted a detailed study of muscle quality, carcass composition, feed/gain ratio and gain rate as affected by varying ratios of …


Corn Vs. Sorghum Grain For Growing-Finishing Pigs (1968), B A. Koch, G Cowman, Robert H. Hines Jan 1968

Corn Vs. Sorghum Grain For Growing-Finishing Pigs (1968), B A. Koch, G Cowman, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Kansas swine growers are quite sure' that corn-fed growing-finishing pigs will outperform those fed sorghum grain. Just as many others feel that sorghum grain is equal to corn in swine rations. Most of the time sorghum grain is lower in price per pound than corn. Research results suggest that corn and sorghum grain are quite similar in chemical composition and in feeding value. Sorghum grain is more variable in crude protein content than corn. One recent comparison between corn and sorghum grain is summarized in this report.; Swine Day, Manhattan, KS, September 26, 1968


Barrow, Gilt Comparisons -- Gains And Carcass Composition At Various Ration Protein Levels (1968), Donald H. Kropf, L H. Kasten, B A. Koch, Robert H. Hines Jan 1968

Barrow, Gilt Comparisons -- Gains And Carcass Composition At Various Ration Protein Levels (1968), Donald H. Kropf, L H. Kasten, B A. Koch, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Many studies have reported that barrows gain more rapidly than gilts, but gilts excell in carcass muscling and trimness. Recently, considerable interest has been directed toward determining ration protein needs of barrows compared to gilts, with a strong possibility that these protein needs differ. If this is true, feeding barrows and gilts separately may be recommended.; Swine Day, Manhattan, KS, September 26, 1968


Ddvp (Shell Dichlorvos) For Pregnant Sows (1968), B A. Koch, G L. Cowman, Robert H. Hines Jan 1968

Ddvp (Shell Dichlorvos) For Pregnant Sows (1968), B A. Koch, G L. Cowman, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Recent laboratory and research station reports have indicated that 2,2-dichlorovinyl dimethyl phosphate (DDVP) (Shell Dichlorvos) fed to pregnant sows late in gestation may have a favorable effect on the newborn pigs. This study was designed to attempt to measure that effect in terms of increased production or improved efficiency in a commercial herd. The commercial swine herd of Arnold and Bob Rose (Cawker City, Kansas) was used in this study which was financed by the Shell Chemical Company. The Rose herd is one of the larger outstanding commercial pork producing units in Kansas. For all practical purposes it is an …


The Effect Of Protein Level And Added Amino Acids In Sorghum Grain-Soybean Meal Rations For Swine (1968), B A. Koch, R D. Howard, Donald H. Kropf, Robert H. Hines Jan 1968

The Effect Of Protein Level And Added Amino Acids In Sorghum Grain-Soybean Meal Rations For Swine (1968), B A. Koch, R D. Howard, Donald H. Kropf, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

More information is needed on the optimum level of protein in sorghum grain-soybean meal rations for swine. Theoretically the protein value of a swine ration should be improved if the most limiting amino acids are added. This experiment was conducted to determine the most favorable level of protein in sorghum grain-soybean meal rations and the effect of added lysine and methionine.; Swine Day, Manhattan, KS, September 26, 1968


Animal Protein As A Source Of Unidentified Growth Factors For Swine (1968), B A. Koch, G Cowman, Robert H. Hines Jan 1968

Animal Protein As A Source Of Unidentified Growth Factors For Swine (1968), B A. Koch, G Cowman, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Most authorities agree that the value of a protein source is determined by its content of essential amino acids. On that basis soybean meal compares favorably' with the other commonly fed animal protein sources. However, there is some evidence, especially in the poultry research literature, that certain animal protein sources may contain unidentified growth factors. This report describes a trial in which two different animal proteins were fed at the 5% level in place of soybean meal in growing finishing-swine rations.; Swine Day, Manhattan, KS, September 26, 1968


Estrus Synchronization In Swine: Trials With Aimax (I.C.I. 33,838) (1968), G Kiracofe, B A. Koch, Robert H. Hines Jan 1968

Estrus Synchronization In Swine: Trials With Aimax (I.C.I. 33,838) (1968), G Kiracofe, B A. Koch, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Several methods of synchronizing estrus have been tried in swine. One of the oldest and most commonly used natural methods is weaning pigs from a group of sows simultaneously. When this is done, the majority of sows will show estrus 3 to 7 days later if the sows have been nursed for at least 3 weeks. This method is effective and highly fertile; however, in some cases it is not practical to breed at this time and a natural method of synchronization in gilts is not available.; Swine Day, Manhattan, KS, September 26, 1968
