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, …

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

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

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

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 …

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

The Value Of An Artery Clamp To Dehorn Cattle, C.L. Drake, R.R. Schalles, C.W. Smith Jan 1968

The Value Of An Artery Clamp To Dehorn Cattle, C.L. Drake, R.R. Schalles, C.W. Smith

Kansas Agricultural Experiment Station Research Reports

A preliminary trail involving use of an artery clamp and a drawing and description of the clamp are reported in Bulletin 507. This trial involved 42 horned heifers owned and fed by a cooperating feedlot operator. The heifers were individually weighed and placed on these experimental treatments: 1. Control - not dehorned 2. Dehorned using clamp; arteries pulled 3. Dehorned not using clamp; arteries pulled All heifers were placed in one large lot and fed the same ration for 30 days after being dehorned.

High Protein Sorghum Grain With No Added Protein In All Concentrate Cattle Finishing Rations; Urea And Soybean Oil Meal In All Concentrate Rations, E.F. Smith, D. Richardson, C.L. Drake, B.E. Brent Jan 1968

High Protein Sorghum Grain With No Added Protein In All Concentrate Cattle Finishing Rations; Urea And Soybean Oil Meal In All Concentrate Rations, E.F. Smith, D. Richardson, C.L. Drake, B.E. Brent

Kansas Agricultural Experiment Station Research Reports

Trials at several research centers as well as in Kansas (Bulletin 483, page 32) have shown roughage may be satisfactorily omitted from finishing rations for cattle and doing so, often reduces feed required per pound of gain. That has made it feasible to try to finish cattle on all grain diet5, when the grain has sufficient protein, and to omit other protein sources as well as roughage. Other research on this subject is reported in Kansas Bulletins 493 and 507 and on page in this bulletin.

A Comparison Of All-In-One And Conventional Sorghum Silage With And Without Mga For Feedlot Heifers, L.I. Smart, C.L. Drake Jan 1968

A Comparison Of All-In-One And Conventional Sorghum Silage With And Without Mga For Feedlot Heifers, L.I. Smart, C.L. Drake

Kansas Agricultural Experiment Station Research Reports

Silage is being utilized in larger quantities in beef cattle growing and fattening rations. Hammes et al. (1964) showed that higher levels of corn silage can be used because gains from high silage and high grain rations are similar. However, more total digestible nutrients may be harvested per acre and the cost of gain is usually less with silage. Several investigators have shown advantages to certain additives with silage.

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 …
