Arthrogryposis In Piglets (1978), H W. Leipold, R Ely, D Schoneweis
Arthrogryposis In Piglets (1978), H W. Leipold, R Ely, D Schoneweis
Kansas Agricultural Experiment Station Research Reports
This report documents experimental reproduction of tetramelic arthrogryposis in purebred Yorkshire swine by breeding trials. Data from the trials indigated arthrogryposis may be due to homozygosity of a simple autosomal recessive gene. No affected pig was observed to be alive at parturition, although most had been alive in utero just prior to delivery. Other than dystocia observed in the sows, no other significant clinical findings were noted. The condition was noted in five litters from two sows which were bred to the same boar. Approximately 25% of the pigs exhibited the clinical signs of arthrogryposis which included malformed rigidly extended …

Select line pigs were compared with those in the control line for growth patterns, production traits, and carcass quality. Heritability and genetic correlations were calculated for certain production and carcass traits after five generations of selection.; Swine Day, Manhattan, KS, November 9, 1978
Evaluation Of A Concentrated Milk Replacer And A Vitamin-Amino Acid-Iron-Electrolyte Supplement On Baby Pig Survival And Performance (1978), D A. Schoneweis, Robert H. Hines
Evaluation Of A Concentrated Milk Replacer And A Vitamin-Amino Acid-Iron-Electrolyte Supplement On Baby Pig Survival And Performance (1978), D A. Schoneweis, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Litters offered a concentrated milk replacer and the vitamin amino acid, iron-electrolyte supplement, weighed the same as control litters at day 10, 14, 21, and 28. Blood analysis revealed no difference in packed cell volume, hemoglobin, or plasma protein between litters offered the supplement and control litters. Survival rate from birth to weaning favored the control litters (93.9 or 85.3%), however all nineteen litters used in this study were healthy with very little scours observed.; Swine Day, Manhattan, KS, November 9, 1978
Using Oral E. Coli Milk Vaccine To Control Colibacillosis (1978), D A. Schoneweis, V Gaeth
Using Oral E. Coli Milk Vaccine To Control Colibacillosis (1978), D A. Schoneweis, V Gaeth
Kansas Agricultural Experiment Station Research Reports
Colibacillosis is still a costly disease to swine producers in spite of new antibiotics and other products and procedures used to prevent or treat the disease. A recent aid in controlling the disease is the oral E. coli milk vaccine developed by Dr. Irvin Kohler. It consists of isolating a pathogenic E. coli from the herd and feeding the organism to pregnant sows to stimulate colostral antibodies. It is a giant step forward from the earlier recommendation of the late Dr. Howard Dunne who suggested taking the bedding and feces from the farrowing house and feeding it to pregnant sows …
Pelleting Corn-Soybean Meal Swine Diets (1978), E R. Skoch, S F. Binder, C W. Deyoe, G L. Allee, Keith C. Behnke
Pelleting Corn-Soybean Meal Swine Diets (1978), E R. Skoch, S F. Binder, C W. Deyoe, G L. Allee, Keith C. Behnke
Kansas Agricultural Experiment Station Research Reports
One hundred forty-six pigs were used to study the effects of steam pelleting a corn-soybean meal diet on pig performance. Treatments included ground meal, meal steam conditioned to 80 C (176 ÌŠF) before pelleting, meal pelleted without steam conditioning, and a meal diet with 2% molasses replacing corn. Steam-conditioning the meal before pelleting resulted in less starch damage, and less electrical energy was required for pelleting. Pellet durability was considerably increased with steam conditioning. None of the processing methods studied caused significant (P<.05) improvement in daily gain, feed efficiency, or energy digestibility for weanling pigs. A significant improvement (P<.05) over the control diet in feed efficiency and energy digestibility, was found with either pelleting treatment for grower-finisher pigs. However, daily gain was not significantly (P<.05) improved.; Swine Day, Manhattan, KS, November 9, 1978

Kansas Agricultural Experiment Station Research Reports
One hundred forty, three-week old weanling pigs were used to evaluate the effects of feeding a heat-processed, predigested liquid diet. In Trial I, pigs were randomly allotted to a dry crumbled diet or a processed liquid diet. The basal corn-soybean meal diet contained 20% protein. A preference trial and a digestion trial were also conducted using the same treatments. A second feeding trial was conducted using a basal diet which contained 30% whey. Treatments consisted of a dry meal diet, a dry meal + water diet, and a processed liquid diet.; Swine Day, Manhattan, KS, November 9, 1978
Performance Of Pigs Fed Corn, Sorghum, Or Wheat With 0 Or 4% Added Fat (1978), G L. Allee
Performance Of Pigs Fed Corn, Sorghum, Or Wheat With 0 Or 4% Added Fat (1978), G L. Allee
Kansas Agricultural Experiment Station Research Reports
We used 96 crossbred pigs averaging 8.3 kg (19.3 lbs.) to compare performances with sorghum, corn, or wheat with 0 or 4% added fat (tallow). The trial ended when pigs averaged approximately 220 pounds. Grain source (sorghum, corn, or wheat) did not affect average daily gain or feed efficiency of pigs during any ration phase (starter, grower, or finisher). Adding fat (to each grain ration) reduced feed intake and improved feed efficiency during each ration phase. The greatest improvement in feed efficiency from added fat was during the finishing phase.; Swine Day, Manhattan, KS, November 9, 1978
Effect Of Fat Thickness And Temperature On Adg And F/G Ratio In Finishing Swine (1978), David A. Nichols, D R. Ames, G L. Allee, Robert H. Hines
Effect Of Fat Thickness And Temperature On Adg And F/G Ratio In Finishing Swine (1978), David A. Nichols, D R. Ames, G L. Allee, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Fat and lean pigs were observed at temperatures of 0(32F), 5(41F), 10(50F), 15(59F), and 20C(68F). In comparing fat and lean pigs no significant differences were observed in feed-to-gain ratio or average daily gain. Pigs housed at 32 and 41F gained significantly slower and less efficiently than those housed at 50, 59, or 68F. No differences in performance were observed among the last three groups. Increased huddling, longer hair coats and increased shivering were observed at the lower temperatures.; Swine Day, Manhattan, KS, November 9, 1978
Studies On The Role Of Solar Ultraviolet Radiation In "Natural" Water Purification By Aquatic Ecosystems, John Calkins, Jeanne A. Barcelo, Perry Grigsby, Stephen Martin
Studies On The Role Of Solar Ultraviolet Radiation In "Natural" Water Purification By Aquatic Ecosystems, John Calkins, Jeanne A. Barcelo, Perry Grigsby, Stephen Martin
KWRRI Research Reports
The possibility that pollution might deplete the stratospheric ozone layer and intensify solar UV at the earth's surface focuses attention on the role of solar UV in the various ecosystems at the earth's surface. Previous studies suggested that solar UV might contribute to bacterial die off in wastewater and the studies reported here were directed toward elucidating the action of solar UV in "natural" waters.
It has been assumed that solar UV action on aquatic ecosystems can be evaluated (using proper models) on the basis of the following four independently measurable quantities: I) the intensity of solar UV at the …
Social Behavior In A Group Of Captive Bobcats : A Study In The Sociability Of Felids, Lon W. House
Social Behavior In A Group Of Captive Bobcats : A Study In The Sociability Of Felids, Lon W. House
Dissertations and Theses
A group of four captive bobcats (Felis rufus), two males and two females, was observed for 102.67 hours over the period of one year. A pilot study was conducted consisting of a minimum of three separate observations for each daylight hour. The remaining observations were concentrated during the early morning hours immediately after feeding, the time of maximum activity and social interaction.
Response Of Yearling Cattle To Burning And Fertilizing Bluestem Pasture And Intensively Stocking Early, E.F. Smith, B. Schalles, L. Harbers, R. Pruitt, Clenton E. Owensby
Response Of Yearling Cattle To Burning And Fertilizing Bluestem Pasture And Intensively Stocking Early, E.F. Smith, B. Schalles, L. Harbers, R. Pruitt, Clenton E. Owensby
Kansas Agricultural Experiment Station Research Reports
Long term (28 years) annual, late spring burning of bluestem pasture produced the most daily gain of all pasture treatments but not significantly more than stocking intensively early. Nitrogen applied to a late-spring-burned pasture did not significantly increase daily cattle gains over those from a similarly burned pasture not fertilized. But the nitrogen increased gain per acre by increasing carrying capacity of the pasture. Performance of animals on pasture stocked at twice the normal rate the first half of the season (intensive stocking early) did not differ from performance under normal stocking (burned with no nitrogen added) for the entire …

Sources Of Forage Adjusted To Temperature Changes For Wintering Cows In Drylot, M. Mckee, K. Kimple, D.R. Ames, C.L. Willms, L.R. Corah
Kansas Agricultural Experiment Station Research Reports
Cows in mid-to-late gestation gained weight when fed either milo stover silage or alfalfa hay-wheat straw but lost weight when the forage source was milo-stover bales. When supplemented with additional corn grain as temperature decreased, cows receiving milo stover stilage or alfalfa hay-wheat straw gained more eight, and cows receiving milo stover bales lost less weight than cows receiving the same forages but fed to NRC (1976) requirements.

Evaluating The Breeding Potential Of Yearling Bulls (Progress Report), L. Corah, G. Kiracofe, V. Bridson, M. Mckee, R.R. Schalles
Kansas Agricultural Experiment Station Research Reports
Although this is based on only ones years' results, it indicates that the breeding potential of yearling bulls can be determined before they are run with a cow herd. In this test one bull sired the majority of the calves and generally was the bull predetermined to be the active breeder. Results of the test suggest that a good, active, breeding yearling bull is capable of breeding more than 12 to 15 cows as is normally recommended. In our studies, one yearling bull sired up to 36 calves in a 45-day breeding season. Possible adverse effects of using a yearling …
The Concept Of Adjusting Energy Level In Maintenance Rations For Cold Weather, D.R. Ames
The Concept Of Adjusting Energy Level In Maintenance Rations For Cold Weather, D.R. Ames
Kansas Agricultural Experiment Station Research Reports
Nutrient requirements for domestic animals (NRC) published by the National Research Council are the best estimates available. For beef cattle, specific tables are listed for animals of different weights and for various stages of the production cycle. Although these values are useful for many situations, there are instances when they should be adjusted. One needed adjustment is energy requirement for maintenance when cattle are exposed to cold and rate of heat production must increase to compensate for increased heat loss. The two factors that determine the rate of heat loss are: (1) the differences between body temperature and environmental temperature, …
