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

Ddvp (Shell Dichlorvos) For Weanling Pigs, B A. Koch, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Recent reports indicate that a low level (25 parts per million of active ingredient) of 2,2 dichlorovinyl dimethyl phosphate (DDVP) increases growth of weanling pigs. The trial reported here was designed to measure such response in pigs from Dichlorvos-fed sows and also in pigs from sows not receiving Dichlorvos during late pregnancy.; Swine Day, Manhattan, KS, September 25, 1969


Lysine Supplementation For Growing-Finishing Swine Rations, B A. Koch, Robert H. Hines Jan 1969

Lysine Supplementation For Growing-Finishing Swine Rations, B A. Koch, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

The protein level and protein quality of swine rations consisting primarily of grain can be changed by adding either protein like soybean meal or individual amino acids like lysine. Protein requirements are based on individual amino acids that compose the protein. Amino acid most lacking in grain proteins is lysine, so lysine is the most limiting amino acid in growing-finishing rations made up primarily of grain. Feeding trials reported here were designed to: (1) compare corn and sorghum grain, (2) determine the value of 0.1% of lysine added to the ration, (3) compare performance of barrows and gilts and ...


Effect Of Oxytocin On Parturition In Sows, G H. Kiracofe, Robert H. Hines Jan 1969

Effect Of Oxytocin On Parturition In Sows, G H. Kiracofe, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

The hormone oxytocin (a hypothalamic neurosecretion that is stored in the posterior pituitary gland) stimulates' uterine contractions during natural parturition. Commerical oxytocin has been used to induce labor or to intensify uterine contractions during difficult or prolonged labor in sows. This test evaluated use of one level of a commercial oxytocin during normal parturition.; Swine Day, Manhattan, KS, September 25, 1969


Low-Level Antibiotics In Growing-Finishing Swine Rations., B A. Koch, Robert H. Hines Jan 1969

Low-Level Antibiotics In Growing-Finishing Swine Rations., B A. Koch, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

The new K-State facilities for growing-finishing swine seemed ideal to re-evaluate various antibiotics as low-level feed additives. The first trial reported here was with the first pigs fed in the new barn. They also were the first farrowed in the new farrowing house, and the first raised in the new nursery. The trials were designed to: (1) compare rations with and without an antibiotic at a low level, (2) various antibiotics and combinations of antibiotics and (3) to determine the need for extra feeder space.; Swine Day, Manhattan, KS, September 25, 1969


Simple And Complex Pig Starters Compared, B A. Koch, Robert H. Hines Jan 1969

Simple And Complex Pig Starters Compared, B A. Koch, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Baby pigs have the ability to grow rapidly and efficiently. Creep rations at an early age enhance their potential. Most commercial creep rations contain feedstuffs to increase palatability and acceptability. Are these ingredients necessary or will rather simple starters produce similar gains? Five starters were compared, varying from a simple corn-milo- soybean meal ration to a ration containing several palatability aiding ingredients--from 10 days of age to weaning at 28-35 days; and from 6 weeks to 10 weeks of age.; Swine Day, Manhattan, KS, September 25, 1969


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

Ddvp (Shell Dichlorvos) For Pregnant Sows, 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 ...


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

Animal Protein As A Source Of Unidentified Growth Factors For Swine., 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


The Effect Of Protein Level And Added Amino Acids In Sorghum Grain-Soybean Meal Rations For Swine, 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, 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


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

Heat - Extruded Sorghum Grain For Growirig - Finishing Swine., 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 ...


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

Corn Vs. Sorghum Grain For Growing-Finishing Pigs, 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, 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, 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


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

Growing - Finishing Rations Supplemented With Zinc - Proteinate, 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


Effects Of Varying Sorghum Grain Soybean Meal Ratios And Added Methionine On Swine Gains, Feed Efficiency And Carcass Composition And Quality, 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, 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 ...


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

Estrus Synchronization In Swine: Trials With Aimax (I.C.I. 33,838), 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
