Performance Of Young Pigs As Affected By Energy Density Of And Method Of Adding Fat To Rations, G L. Allee Jan 1977

Performance Of Young Pigs As Affected By Energy Density Of And Method Of Adding Fat To Rations, G L. Allee

Kansas Agricultural Experiment Station Research Reports

One hundred twenty-six crossbred pigs averaging 11.7 kg. (25.7 lbs.) were used to determine the effects of energy density (added fat or fiber) and calorie-protein, calorie-lysine, and calorie-nutrient ratios of rations on pig performance. The basal sorghum-soybean meal ration contained 16.0% crude protein, 0.80% lysine, 0.70% calcium, and 0.60% phosphorus. Soybean oil was the fat source and cellulose the fiber source. Adding 6% fat and maintaining a constant calorie-lysine, calorie-protein, or calorie-nutrient ratio increased (P<.05) average daily gain and improved (P<.05) feed efficiency, compared with gain and efficiency of pigs fed the basal ration. Pigs fed rations containing 6% fiber had similar average daily gain and feed efficiency as did pigs feed the basal ration.; Swine Day, Manhattan, KS, November 10, 1977


Solar Energy For Preheating Ventilating Air, C K. Spillman, F V. Robbins, B A. Koch Jan 1977

Solar Energy For Preheating Ventilating Air, C K. Spillman, F V. Robbins, B A. Koch

Kansas Agricultural Experiment Station Research Reports

The basic concept of the solar energy collector- storage system for preheating ventilating air is sound, and it should be an economic alternative as energy becomes less available and/or more expensive. Based on current energy prices it can't be justified on a strict economic basis without large tax credits. We plan to continue research, working with other scientists, to develop it so that functional and reliable units can be constructed when our national energy situation demands such a solar energy system.; Swine Day, Manhattan, KS, November 10, 1977


Stress Susceptibility In Pigs Selected For Muscling, J D. Wheat, Donald H. Kropf, Robert H. Hines Jan 1977

Stress Susceptibility In Pigs Selected For Muscling, J D. Wheat, Donald H. Kropf, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Duroc swine selected for muscling seemingly are more susceptible to stress than are ordinary pigs. The highly significant difference in serum creatine phosphokinase (CPK) levels (an average score of 30.07) in those pigs and levels (18.88) in control-line pigs indicates that pigs selected for increased muscling are more susceptible to stress because exercise causes CPK levels to be proportionately higher in their blood serum than would be the case were the pigs not under stress.; Swine Day, Manhattan, KS, November 10, 1977


Pseudorabies, D A. Schoneweis Jan 1977

Pseudorabies, D A. Schoneweis

Kansas Agricultural Experiment Station Research Reports

Pseudorabies has been talked and written about so much the last few years that it seems that there isn't anything left to be said. It may be that so much has been said about the disease that now is the time to review the disease as it relates to Kansas swine producers. First of all, I'd like to discuss briefly two factors that need to be clarified: (1), pseudorabies is not to be confused with rabies--there are no recorded instances of humans being affected by the virus; and (2), pseudorabies is not a new disease. First reported in ...


Efficiency Of Buquinolate In Growing-Finishing Swine Diets, Robert H. Hines Jan 1977

Efficiency Of Buquinolate In Growing-Finishing Swine Diets, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

A feeding trial utilizing one-hundred and twelve growing-finishing Duroc pigs was conducted to evaluate the effect of buquinolate (0, 30, 60, or 90g/t) in their diets on growth, efficiency, and carcass quality. Pigs fed 30g/t or 90g/t buquinolate gained four percent faster than did control pigs; however, the feed required per pound of gain was the same. Carcass quality was similar for all treatment groups.; Swine Day, Manhattan, KS, November 10, 1977


Use Of Oats And Fat In Swine Grower Rations, Robert H. Hines Jan 1977

Use Of Oats And Fat In Swine Grower Rations, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Two feeding trials involving 112 Yorkshire weaned pigs (25 lbs.) were conducted to study the use of oats and fat in grower rations. Adding 3% fat (soy oil) to the fortified corn-soybean control ration reduced daily feed intake, but improved feed efficiency. Incorporating 40% oats in a fortified corn-soybean meal grower ration resulted in similar pig performance for rate of gain, daily feed intake, and feed efficiency even though the ration contained 6.5% fiber. Pigs fed a diet containing 40% oats and 5% fat gained 5% faster and were 10% more efficient than pigs fed the control ration.; Swine ...


Feeding Barrows And Gilts Three Protein Sequences To Heavier Market Weight, Robert H. Hines Jan 1977

Feeding Barrows And Gilts Three Protein Sequences To Heavier Market Weight, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Forty-eight Yorkshire barrows and 48 Yorkshire gilts were fed separately three protein sequences to a finish weight of 250 to 260 lbs. Barrows gained faster and were more efficient on protein sequence B (16% protein diet from 100 to 135 lbs.; then 14% diet to finish weight) and C (same as B except that barrows were switched at 210 lbs. to a 12% diet to final weight) than on A (16% protein diet from 100 lbs. to final weight). Gilts gained fastest and were most efficient when fed sequence A. Both barrows and gilts gained slower after attaining the weight ...


Exhaust Air From A Farrowing House Used To Heat A Greenhouse, J K. Greig, C K. Spillman, B A. Koch Jan 1977

Exhaust Air From A Farrowing House Used To Heat A Greenhouse, J K. Greig, C K. Spillman, B A. Koch

Kansas Agricultural Experiment Station Research Reports

Exhaust air from the Kansas State University swine farrowing house provides most of the heat needed in a greenhouse adjacent to it. The air apparently is not toxic to any of the vegetable plants tested. Tomato plants in the exhaust-air-heated greenhouse have grown faster and bigger, come into yield sooner, and produced several times more tomatoes than have plants grown in the control greenhouse heated by propane.; Swine Day, Manhattan, KS, November 10, 1977


Iron Dextran And Farbegen Compared As Methods Of Preventing Iron Deficiency Anemia In Neonatal Pigs, D A. Schoneweis, G L. Allee Jan 1977

Iron Dextran And Farbegen Compared As Methods Of Preventing Iron Deficiency Anemia In Neonatal Pigs, D A. Schoneweis, G L. Allee

Kansas Agricultural Experiment Station Research Reports

The experiment suggests that a primary need of the neonatal pig is iron and that hematinics such as cobalt and liver extract are of little value if iron is insufficient.; Swine Day, Manhattan, KS, November 10, 1977


Iron Dextran And Iron Dextran-Gentamycin Combined, Compared As Methods Of Preventing Iron-Deficiency Anemia In Neonatal Pigs, D A. Schoneweis, G L. Allee Jan 1977

Iron Dextran And Iron Dextran-Gentamycin Combined, Compared As Methods Of Preventing Iron-Deficiency Anemia In Neonatal Pigs, D A. Schoneweis, G L. Allee

Kansas Agricultural Experiment Station Research Reports

Giving an iron iron dextran-gentamycin combination to young pigs had no advantages over giving them iron dextran alone, as measured by hemoglobin levels, packed cell volumes, or weight (when 28 days old).; Swine Day, Manhattan, KS, November 10, 1977


Antibiotics - Yes Or No?, J E. Mosier Jan 1977

Antibiotics - Yes Or No?, J E. Mosier

Kansas Agricultural Experiment Station Research Reports

From January, 1976, to January, 1977, I served as chairman of a subcommittee of the National Advisory Food &Drug Consultants charged with examining several issues concerned with the "Use of Antibiotics in Animal Feeds". It was through the activities of this subcommittee that I have had the opportunity to review papers and to hear presentations and discussions by many knowledgeable people concerning such use. Most of you are fully cognizant that the use of antibiotics in animal feeds originated from the observations of Jukes and Stokstad in 1949. Subtherapeutic levels are used for increasing weight gain, improving feed efficiency, and preventing or controlling animal disease. In 1973 in the United States, 20.8 million pounds of antibiotics were produced--12.6 million destined for medicinal use and 8.2 million pounds for nonmedical use, primarily in animal feeds.; Swine Day, Manhattan, KS, November 10, 1977


Ksu Aerobic Swine Waste Handling System - A Progress Report, B A. Koch, G L. Allee, R I. Lipper, Robert H. Hines Jan 1977

Ksu Aerobic Swine Waste Handling System - A Progress Report, B A. Koch, G L. Allee, R I. Lipper, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

At the KSU swine research unit, the aerobic oxidation waste-disposal system continues to function satisfactorily. Though problems and maintenance are minimal, routine observation and maintenance are necessary to prevent development of problems. Odor is not a problem. Waste fluid can be spread on fields any time that soil is not too wet and--regardless of wind direction or humidity conditions--nearby neighbors do not complain. Pigs are performing satisfactorily in all buildings. Flies are easily controlled, suitable sanitation is easily maintained, and working conditions are satisfactory.; Swine Day, Manhattan, KS, November 10, 1977


Scrotal Measurements And Visual Scores Of Boar Testicle Size Correlated With Testicle Weight, Duane L. Davis, Robert H. Hines Jan 1977

Scrotal Measurements And Visual Scores Of Boar Testicle Size Correlated With Testicle Weight, Duane L. Davis, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Scrotal measurements and visual scores of testicle size were determined for 59 boars used in nutrition and physiology studies. The best predictors of testicular weight were visual scores (average of 3 observers) and partial-circumference measurements. Though visual score was an accurate predictor within groups scored at the same time, it was not a dependable predictor when it included combined scores of groups scored at different times.; Swine Day, Manhattan, KS, November 10, 1977


Efficacy Of Iron Proteinate Fed To Sows In Meeting The Iron Needs Of Baby Pigs, D A. Schoneweis, G L. Allee Jan 1977

Efficacy Of Iron Proteinate Fed To Sows In Meeting The Iron Needs Of Baby Pigs, D A. Schoneweis, G L. Allee

Kansas Agricultural Experiment Station Research Reports

Two trials involving 33 litters of pigs and more than 1,300 blood samples demonstrated that feeding iron proteinate (250 PPM) to the sows during the last one-third of gestation and lactation is not an effective way to supply the iron needs of baby pigs if they have limited access to the sows’ fecal material.; Swine Day, Manhattan, KS, November 10, 1977


Restricting Energy Intake Of Gestating Sows With 50% Alfalfa Meal Ration, G L. Allee, B A. Koch, Robert H. Hines Jan 1977

Restricting Energy Intake Of Gestating Sows With 50% Alfalfa Meal Ration, G L. Allee, B A. Koch, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Gestating Yorkshire sows and gilts were randomly assigned to two dietary treatments immediately after a 25-day breeding season until females were brought to the farrowing house between 105-110th day of gestation. Sows and gilts fed the 50% alfalfa meal ration performed similarly to those fed the basal ration in regard to number of pigs farrowed, pigs weaned, and weights at birth, 14 and 28 days. The reduced caloric intake by sows fed 50% alfalfa meal was not detrimental to farrowing or reproductive performance.; Swine Day, Manhattan, KS, November 10, 1977


Flavor Enhancers And/Or Vitamin C In Growing-Finishing Rations, B A. Koch, G L. Allee, Robert H. Hines Jan 1977

Flavor Enhancers And/Or Vitamin C In Growing-Finishing Rations, B A. Koch, G L. Allee, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Supplemental vitamin C fed at two different levels (550 or 1,100mg, per kg, of diet) did not improve animal performance at the swine research center. Adding apple flavor or sodium bicarbonate did not change results.; Swine Day, Manhattan, KS, November 10, 1977


Blended Dried Bakery Product In Swine Starter Rations, G L. Allee Jan 1977

Blended Dried Bakery Product In Swine Starter Rations, G L. Allee

Kansas Agricultural Experiment Station Research Reports

A growth trial, a digestion trial, and a preference trial were conducted to evaluate a blended dried bakery product (BDBP) as an ingredient in swine starter rations. Replacing 0, 10, 20, or 30% corn with BDBP had no effect on average daily gain or feed efficiency. When given a choice, pigs preferred a ration containing 20% BDBP. The energy and protein digestibilities in BOBP were 91.5% and 87.88%, respectively.; Swine Day, Manhattan, KS, November 10, 1977


Comparison Of Anthelmintic And Anti-Bacterial Agents Fed Weanling Pigs Reared On Pasture, B A. Koch, S M. Kruckenberg, Robert H. Hines Jan 1977

Comparison Of Anthelmintic And Anti-Bacterial Agents Fed Weanling Pigs Reared On Pasture, B A. Koch, S M. Kruckenberg, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Forty-eight Yorkshire pigs averaging 35 lbs. were used to compare their performance under these feeding sequences: (A) mecadox plus banminth, received until weighing 75 lbs., followed by terrarnyci n to 125 lbs.; (B) worming with tramisol initially and feeding ASP-250 until weighing 125 lbs. To market weight, pigs in both treatment groups were fed a nonmedicated finisher diet. Rate of gain was similar for both treatments; the sequence A pigs, however, required 6% fewer lbs. of feed per pound of gain. Pigs fed banminth had, after 35 days, no ascarid scars in their livers and no ascarids in their intestines ...


Calcium Phosphorus Levels For Developing Boars, J G. Greer, Duane L. Davis, Robert H. Hines Jan 1977

Calcium Phosphorus Levels For Developing Boars, J G. Greer, Duane L. Davis, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Forty-two boars averaging 67 lbs. were used to study how various levels of calcium and phosphorus in their feed affected their development. Calcium-to phosphorus ratios of 1.2 to 1 were maintained in all treatment diets, which ranged from a low of .55% calcium and .45% phosphorus to a high of 1.30% calcium and 1.05% phosphorus. Seven treatment groups were replicated three times. No significant differences were observed for average daily gain, feed efficiency, carcass length, and backfat. Based on this trial, it appears that 0.55% calcium and 0.45% phosphorus is adequate for optimum growth of ...


Rations Containing Sorghum, Corn, Or Wheat With 0 Or 4% Added Fat For Weaned Pigs, G L. Allee Jan 1977

Rations Containing Sorghum, Corn, Or Wheat With 0 Or 4% Added Fat For Weaned Pigs, G L. Allee

Kansas Agricultural Experiment Station Research Reports

One hundred eight crossbred, weaned pigs averaging 10.0ks (22.1 lbs.) were used to compare rations containing sorghum, corn, or wheat with 0 or 4% added fat (tallow) on performance of young pigs. There were no significant differences in average daily gain or feed efficiency among pigs fed sorghum, corn, or wheat with no added fat; and adding 4 % fat to the rations did not affect gain but did result in a slight improvement in feed/gain.; Swine Day, Manhattan, KS, November 10, 1977


Effect Of Choline Supplementation To Corn-Soybean Meal Rations On Pig Performance, G L. Allee Jan 1977

Effect Of Choline Supplementation To Corn-Soybean Meal Rations On Pig Performance, G L. Allee

Kansas Agricultural Experiment Station Research Reports

Eight-four crossbred gilts initially averaging 8.2 kg. (18.0 lbs.) were used to evaluate the effects of supplemental choline to corns-soybean meal rations on pig performance. Four levels of choline were fed during each ration phase (starter, grower, finisher). The trial was terminated when pigs within a replicate averaged approximately 100 kg. (220lbs.). Supplemental choline had no significant effect on average daily gain or feed efficiency.; Swine Day, Manhattan, KS, November 10, 1977


Blended Dried Bakery Product In Swine Finishing Rations, G L. Allee Jan 1977

Blended Dried Bakery Product In Swine Finishing Rations, G L. Allee

Kansas Agricultural Experiment Station Research Reports

Eighty-four crossbred pigs averaging 43.6 kg. (95.9 lbs.) initially were used to evaluate the use of a blended dried bakery product (BDBP) in rations for finishing pigs. Replacing 0, 10, 20, or 30% of the sorghum in the basal ration with BDBP resulted in a small increase (0.06-0.08 lbs./ day) in average daily gain of the pigs and significantly improved their feed efficiency. Twenty percent BDBP appeared to give the best results; however, 30% had no adverse effects.; Swine Day, Manhattan, KS, November 10, 1977


Effect Of Grain Source And 0 Or 4% Added Fat On Performance Of Finishing Pigs, G L. Allee Jan 1977

Effect Of Grain Source And 0 Or 4% Added Fat On Performance Of Finishing Pigs, G L. Allee

Kansas Agricultural Experiment Station Research Reports

Seventy-two crossbred finishing pigs averaging 55.9 kg. (123.0 lbs.) were used (in a 3 x 2 factorial design) to compare performance when fed sorghum, corn, or wheat with 0 or 4% added fat (tallow). There were no significant differences in average daily gain or feed efficiency among pigs fed sorghum, corn, or wheat. Adding 4% fat (to each grain ration) resulted in a slight improvement in gain and an improved feed efficiency. Pigs fed wheat with 4% fat added showed The greatest improvement in daily gain and feed efficiency.; Swine Day, Manhattan, KS, November 10, 1977
