Evaluation Of Ground Corn Germ As An Energy Source In Nursery Diets, C W. Hastad, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz Jan 2001

Evaluation Of Ground Corn Germ As An Energy Source In Nursery Diets, C W. Hastad, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Two hundred eighty nursery pigs (initially 30.9 lb) were used in a 21-d growth assay to determine the energy value of ground corn germ relative to corn oil in nursery diets. Increasing dietary corn oil linearly decreased average daily feed intake and improved feed efficiency. However, pigs fed diets containing ground corn germ meal had similar gain and feed efficiency as those fed the corn-soybean meal diet without added fat. These results suggest that the added energy provided by corn germ is not utilized as well as that from corn oil.; Swine Day, Manhattan, KS, November 15, 2001

Evaluating Cloves As A Potential Substitute For Antimicrobials In Nursery Pig Diets, R G. Main, J Ernest Minton, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

We conducted two trials to evaluate the effects of feeding graded levels of cloves to weanling pigs as a substitute for antimicrobials. In the first trial, improvements in ADG were observed in pigs fed the lowest level of clove addition (0.5%) and for those fed carbadox (50 g/ton). The higher levels of clove inclusion (1.0% and 2.0%) tended to reduce feed intake. A second trial was conducted evaluating performance of pigs fed diets containing 0.125%, 0.25% and 0.5% cloves (a different batch than used in trial 1). The was no ADG improvement from ...

Effects Of A Direct Fed Microbial (Dmf-4) And In-Feed Antimicrobials On Pig Performance In A Commercial Finishing Facility, R G. Main, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 1,000 barrows were used in a 98-day trial conducted in a commercial research facility to determine the influence of a direct fed microbial with and without intermittent treatments of oxytetracycline (OTC) at 400 g/ton. The direct fed microbial was compared to a negative (no feed antimicrobial) and positive control (bacitracin methylene diasalicylate (BMD) at 30 g/ton, alternated with intermittent treatments of OTC at 400 g/ton). No significant differences between the four treatments were observed for any of the growth, efficiency, or carcass parameters evaluated. These results suggest that further work in quantifying the ...

The Influence Of Dietary Energy Level On The Response To Betaine, M G. Young, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 2001

The Influence Of Dietary Energy Level On The Response To Betaine, M G. Young, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 800 pigs were used to evaluate the influence of dietary energy level on the response to betaine in finishing pig diets. Dietary treatments were arranged in a 2 × 2 factorial with or without betaine and two energy density levels as the main effects. No betaine × energy interactions (P>0.05) were observed for the entire feeding period (51 to 210 lb) or for any of the three dietary phases. Pigs fed the high energy diets with added fat had (P<.05) greater ADG, lower ADFI, and improved F/G compared with pigs fed the low energy diets without added fat. Adding betaine to the diet had no influence on pig performance.; Swine Day, Manhattan, KS, November 15, 2001


Influence Of Different Equipment Protocols On Particle Size Determination Of Ground Corn, J C. Woodworth, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach, Steven S. Dritz Jan 2001

Influence Of Different Equipment Protocols On Particle Size Determination Of Ground Corn, J C. Woodworth, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Two experiments were conducted to determine the influence of the tapping bar and sieve agitators (balls and brushes) on determining mean particle size and standard deviation of ground corn. Tapping bar had no influence (P>0.10) on mean and standard deviation; however the presence of balls and brushes on sieves decreased (P<0.002) mean particle size and increased (P<0.0001) standard deviation. These results suggest that balls and brushes should be used when determining mean particle size to assist particle flowability. More research should be conducted to determine the effects of the tapping bar and sieve agitators over a wider range of particle sizes.; Swine Day, Manhattan, KS, November 15, 2001

The dietary treatments consisted of a control diet (no added niacin) or the control diet with 12.5, 25, 50, 100, or 500 g/ton of added niacin. Increasing dietary niacin decreased ADFI and improved F:G for the overall study. Increasing dietary niacin improved carcass shrink, ultimate pH, drip loss percentage, and loin color. Increasing dietary niacin up to 50 ppm improved feed efficiency, but higher concentrations (up to 50 ppm ...


Effects Of Ingredient And Whole Diet Irradiation On Nursery Pig Performance, J C. Woodworth, M J. Webster, B W. James, D E. Real, Joel M. Derouchey, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz Jan 2001

Effects Of Ingredient And Whole Diet Irradiation On Nursery Pig Performance, J C. Woodworth, M J. Webster, B W. James, D E. Real, Joel M. Derouchey, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Two trials were conducted to determine the effects of irradiation of individual ingredients or the whole diet on growth performance in nursery pigs. The response was similar for both trials with pigs fed diets containing irradiated spray-dried animal plasma or soybean meal having increased (P<0.05) ADG compared with pigs fed the control diet with no irradiated ingredients or the complete diet that was irradiated. Also, ADFI (P<0.05) was higher for pigs consuming the diet with irradiated soybean meal compared with those fed the irradiated whole diet. Pigs fed irradiated spray-dried animal plasma also had superior F/G (P<0.05) compared with those fed diets containing irradiated microingredients or if all ingredients had been irradiated before manufacturing. Therefore, irradiation of certain feed ingredients can improve growth performance in nursery, whereas irradiation of all ingredients in the diet or the whole diet does not enhance performance.; Swine Day, Manhattan, KS, November 15, 2001

Utilizing Infrared Thermography To Predict Pork Quality, T E. Lawrence, M F. Spire, Michael E. Dikeman, Melvin C. Hunt, S B. Hogge, B W. James

Kansas Agricultural Experiment Station Research Reports

Three experiments using 63 pigs were conducted to determine if infrared thermography could segregate pigs based on subsequent pork quality. Pigs were subjectively classified as either “hot” or “normal” based on infrared surface temperature of the loin region prior to slaughter. In the first experiment 18 market weight pigs were transported, imaged by infrared thermography and slaughtered immediately after 1 to 4 h of lairage. Differences in meat quality were detected; hot pigs had lower a* (less red) and chroma (less intense red color) values, and higher hue angle (less red/more yellow) values, all of which indicate ...

Evaluation Of Different Copper Sources As A Growth Promoter In Swine Finishing Diets, C W. Hastad, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Two trials were conducted to determine the effects of added copper from copper sulfate or copper chloride on performance of growing-finishing pigs. A total of 2,277 pigs with an initial weight of 71.6 lb were used in a commercial research facility in southwest Minnesota. Adding copper to the diet improved performance during the first two weeks in the finishing barn regardless of copper source or level. The results of these experiments indicate that low levels of copper chloride or copper sulfate (50 to 100 ppm) can be an effective and economical growth promoter when fed for the first ...


Comparison Of Bioaerosol Sampling Methods For Swine Barns, B Z. Predicala, J E. Urban, S B. Jerez, Ronaldo G. Maghirang, Robert D. Goodband Jan 2001

Comparison Of Bioaerosol Sampling Methods For Swine Barns, B Z. Predicala, J E. Urban, S B. Jerez, Ronaldo G. Maghirang, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Two bioaerosol sampling methods (Andersen sampler and filtration sampler) were compared. The two samplers were used to assess the bioaerosol loads in two swine finishing barns. They were similar in terms of the species of microorganisms sampled. The persistent strains of microorganisms were various species of the following genera: Staphylococcus, Pseudomonas, Bacillus, Listeria, Enterococcus, Nocardia, Lactobacillus, and Penicillium. However, the use of Andersen sampler resulted in significantly higher bioaerosol concentrations than the filtration sampler. Thus, it appears that filtration sampling can be used for a qualitative survey of bioaerosols in swine barns while the Andersen sampler is suitable for both ...

Comparison Of Yellow Dent And Nutridense Corn Hybrids For Nursery Pig Diets, C W. Hastad, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 315 nursery pigs (initially 33.5 lb) were used in a 21-d growth assay to compare relative energy values of ‘Nutridense’ and ‘Nutridense Low Phytate’ corn compared to Yellow Dent corn. Dietary treatments consisted of a 3 × 3 factorial with three sources of corn with 0, 3, or 6% added fat. Increasing the energy density of the diet with added fat or higher energy corn varieties (Nutridense or Nutridense-LP corn) linearly improved feed efficiency. The linear improvement in feed efficiency allowed us to calculate the energy content of the Nutridense corn varieties relative to ...


Interactive Effects Of Carnitine Status, Dietary Carnitine, And Added Fat On Growth Performance Of Weanling Pigs, J C. Woodworth, K Q. Owen, J Lopez, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach, Steven S. Dritz Jan 2001

Interactive Effects Of Carnitine Status, Dietary Carnitine, And Added Fat On Growth Performance Of Weanling Pigs, J C. Woodworth, K Q. Owen, J Lopez, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Two experiments were conducted to determine the interactive effects of carnitine status (with or without carnitine in diets fed to sows in gestation and lactation), and added fat and dietary carnitine in nursery diets on growth performance of weanling pigs. Feeding sows diets containing carnitine in gestation and lactation had no effect on growth performance of their pigs through 27-d after weaning. A carnitine by fat interaction (P<0.05) was observed for ADFI from d 0 to 7 and ADG from d 0 to 27 in Exp. 1 with pigs fed carnitine and no added fat appearing to have the best performance. In exp. 2, added carnitine had little effect on growth performance, whereas added fat improved feed efficiency. In conclusion, no benefit to growth performance was observed from adding both carnitine and fat to the diet of weanling pigs in these experiments.; Swine Day, Manhattan, KS, November 15, 2001

Kansas Agricultural Experiment Station Research Reports

A total of 360 pigs were used in two experiments to determine the effects of decreasing particle size of soybean meal on nursery pig performance. In Exp. 1, pigs were fed diets containing 34% extrudedexpelled soybean meal ground to 965, 742, or 639 microns. In Exp. 2, pigs were fed the same diet containing solvent extracted soybean meal ground to 1226, 797, or 444 microns. Decreasing soybean meal particle size did not influence pig growth performance in either study.; Swine Day, Manhattan, KS, November 15, 2001


The Relationship Between Body Condition Score And Backfat In Gestating Sows, M G. Young, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 2001

The Relationship Between Body Condition Score And Backfat In Gestating Sows, M G. Young, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Backfat and body condition score were measured on 731 sows in a commercial swine facility to assess the accuracy of feeding sows in gestation based on body condition score. Body condition score was poorly correlated (r2 = 0.19) with backfat thickness. For example, sows assessed with a body condition of 3 ranged in backfat from 0.3 to 0.9 in. (7.5 to 23 mm). This illustrates the need to find a more objective method of measuring body condition (such as ultrasound) in order to properly adjust feeding levels and thus reduce variation in backfat of sows.; Swine Day ...


Effects Of Feeding Graded Levels Of Ractopamine (Paylean Tm) On Pig Performance In A Commercial Finishing Facility, R G. Main, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 2001

Effects Of Feeding Graded Levels Of Ractopamine (Paylean Tm) On Pig Performance In A Commercial Finishing Facility, R G. Main, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 880 pigs were used in a 21-day trial conducted in a commercial research facility to determine the influence of feeding graded levels (0, 4.5, 6.75, and 9.0 g/ton) of ractopamine HCl (PayleanTM, Elanco Animal Health) on pig performance and carcass composition. Ractopamine supplementation improved ADG 17 to 22% and F/G 12 to 20%. Increasing ractopamine dosages resulted in improved F/G, but similar ADG. With the exception of a tendency to increase yield, carcass parameters were not different among treatments. Ractopamine supplementation resulted in improved economic returns ($2.55 to $3.20 ...

The Optimal Threonine:Lysine Ratio To Maximize Growth Performance Of Nursery Pigs, B W. James, J C. Woodworth, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Joel M. Derouchey, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 210 pigs (initially 18.2 lb and 25 d of age) were used in a 21-d growth assay. The seven treatments consisted of a basal diet (14.1% CP) with increasing levels of threonine (45, 50, 55, 60, 65, and 70% of 1.07% apparent digestible lysine) and a negative control containing 0.97% lysine. Increasing dietary threonine improved feed efficiency; however, there was no improvement in growth performance between pigs fed 0.97 and 1.07% apparent digestible lysine. Therefore, these results suggest the requirement for apparent digestible threonine is approximately 60% of lysine for 18- ...
