Determination Of Contract Base Payments To Feeder-Pig Finishers (1996), J L. Parcell, Michael R. Langemeier Jan 1996

Determination Of Contract Base Payments To Feeder-Pig Finishers (1996), J L. Parcell, Michael R. Langemeier

Kansas Agricultural Experiment Station Research Reports

Risks associated with independent feeder-pig finishing have prompted finishers to seek alternative finishing and marketing methods. A means of reducing risk has developed through contract feeder-pig finishing. Research results indicated that slightly risk-averse finishers required contract base payments ranging from $11.00 to $30.00 per head. Strongly risk-averse finishers required contract base payments ranging from $8.50 to $19.00 per head. The lower end of the ranges is for a low-profit finisher. The upper end of the ranges is for a high-profit finisher.; Swine Day, Manhattan, KS, November 21, 1996

Pigs fed diets with soybean oil consumed less feed; grew more efficiently; and had greater last-rib backfat thickness, keratosis, and ulceration in their stomachs than pigs fed diets without soybean oil. Pigs fed diets with NaHC03 tended to eat more feed and had numerically greater ADG, but feed/gain and carcass measurements were not affected. NaHC03 decreased ulceration scores only for pigs fed diets without added fat.; Swine Day, Manhattan, KS, November 21, 1996

Performance Of Weanling Pigs Fed Diets Containing Various Lactose Sources (1996), P R. O'Quinn, J R. Bergstrom, J A. Loughmiller, R E. Musser, W B. Nessmith Jr, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

Two growth trials were conducted to evaluate the effects of replacing the lactose provided by dried whey in the phase II diet with either deproteinized whey or an alternative lactose source, DairyLac 80®. No differences in performance observed among pigs fed diets containing 10% dried whey or deproteinized whey or DairyLac 80®. These trials indicate that deproteinized whey and DairyLac 80® can be used to replace the lactose contained in dried whey for starter pig diets.; Swine Day, Manhattan, KS, November 21, 1996


Effects Of Select Menhaden Fish Meal Fed During Lactation On Sow And Litter Performance (1996), R E. Musser, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz Jan 1996

Effects Of Select Menhaden Fish Meal Fed During Lactation On Sow And Litter Performance (1996), R E. Musser, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 317 lactating sows was fed either a corn-soybean meal diet (l.0%lysine) or a diet with a portion of the soybean meal replaced with 5% select menhaden fish meal on an equal lysine basis. Adding 5% select menhaden fish meal had no overall effect on sow or litter performance. Composition of milk samples collected between d 14 and 16 of lactation was not affected by dietary treatment.; Swine Day, Manhattan, KS, November 21, 1996


Effects Of Spray-Dried Blood Cells In Lactation Diets On Sow And Litter Performance (1996), E Weaver, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz Jan 1996

Effects Of Spray-Dried Blood Cells In Lactation Diets On Sow And Litter Performance (1996), E Weaver, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

High producing sows were used to evaluate the effect of spray-dried blood cells as a dietary protein source on lactation performance and subsequent reproductive performance. No significant differences were observed between sows fed a corn-soybean cells-based diet or a diet containing 2.5% spray-dried blood cells for lactation performance or subsequent reproductive performance. Therefore, spray-dried blood cells can be used as a partial replacelnent for the protein source in lactation diets.; Swine Day, Manhattan, KS, November 21, 1996

Evaluation Of The Total Sulfur Amino Acid Requirement Of Finishing Pigs (1996), J A. Loughmiller, J W. Smith Ii, J R. Bergstrom, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Sixty four gilts (initially 120 lb) were used to evaluate the effects of increasing total sulfur amino acid (TSAA):lysine ratios on growth performance and carcass characteristics. Diets included two levels of lysine (.55% and .70% total lysine) and three TSAA:lysine ratios (60, 65, and 70% of lysine) arranged in a 2 x 3 factorial. A tendency for a lysine x TSAA interaction was observed for ADG and ADFI. Increasing TSAA:lysine ratio decreased ADG and ADFI in pigs fed .55% lysine; however, ADG and ADFI were increased in pigs fed .70% lysine and 65% TSAA:lysine. Pigs fed .70% lysine had improved …

Kansas Agricultural Experiment Station Research Reports

Early-weaned pigs (weaned at 14 d of age) that are managed in a conventional one-site production system and fed a complex segregated early-weaning diet will benefit from the inclusion of a diet acidifier during the first week. However, the data indicate no benefit from including a diet acidifier in semicomplex diets fed during subsequent growth phases.; Swine Day, Manhattan, KS, November 21, 1996

Kansas Agricultural Experiment Station Research Reports

Thirty six Yorkshire gilts (initially 123 lb BW) were used to investigate the effect of dietary carnitine on growth performance, carcass characteristics, fatty acid oxidation, and enzyme kinetics. Dietary carnitine reduced fat deposition in favor of protein deposition, stimulated fatty acid oxidation, induced the expression of pyruvate carboxylase, increased the capacity of pyruvate carboxylase flux, and decreased the capacity of branch chain keto dehydrogenase.; Swine Day, Manhattan, KS, November 21, 1996


Influence Of Lysine Concentration On Growth Performance And Carcass Characteristics Of Finishing Pigs (1996), Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz Jan 1996

Influence Of Lysine Concentration On Growth Performance And Carcass Characteristics Of Finishing Pigs (1996), Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

We used a total of 11,653 pigs to examine the influence of a lysine phase-feeding regimen on growth performance and carcass characteristics in finishing pigs. We found that the lysine regimen did not affect ADG. Also, the low-lysine regimen was adequate for maximizing growth performance and carcass characteristics of barrows. However, the low-lysine regimen was inadequate to optimize feed efficiency in gilts. Further analysis indicated that the largest differences in feed efficiency were for the 115 to 160 lb period in gilts. Later in the growth period, feed efficiency of gilts was similar across dietary lysine regimens.; Swine Day, Manhattan, …


Swine Manure Management (1996), James P. Murphy Jan 1996

Swine Manure Management (1996), James P. Murphy

Kansas Agricultural Experiment Station Research Reports

Manure nutrients help build and maintain soil fertility. Manure also improves tilth, increases waterholding capacity, lessens wind and water erosion, improves aeration, and promotes beneficial organisms. When wastes include runoff or dilution water, they can supply water as well as nutrients to crops. The economic value of manure fertilizer is calculated from its available nitrogen (N), phosphorus (P), and potassium (K) at commercial fertilizer prices. These values change with the costs of fertilizer and handling practices.; Swine Day, Manhattan, KS, November 21, 1996

Kansas Agricultural Experiment Station Research Reports

Eighty pigs, 40 barrows and 40 gilts, on two commercial finishing operations were used to model growth and accretion rates. Major differences were observed between the two farms. This analysis indicates that realtime ultrasound can be used to develop lean and lipid accretion curves for formulating farm-specific diets that optimize lean growth performance in commercial operations.; Swine Day, Manhattan, KS, November 21, 1996

Kansas Agricultural Experiment Station Research Reports

Eighty crossbred gilts (initially 83 lb)were used to examine the effects of 50 ppm carnitine and(or) 200 ppb chromium from chromium nicotinate on growth performance and carcass characteristics. In this trial, adding carnitine and(or) chromiun1 to the diets of high-lean growth finishing gilts did not increase carcass leanness. However, the combination of carnitine and chromium improved the color characteristics of the longissimus muscle.; Swine Day, Manhattan, KS, November 21, 1996


Dietary Lysine Requirement For Optimal Growth Performance And Carcass Characteristics Of Late Finishing Gilts (1996), J A. Loughmiller, I H. Kim, J C. Woodworth, J W. Smith Ii, J R. Bergstrom, K Hongtrakul, W B. Nessmith, R E. Musser, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach Jan 1996

Kansas Agricultural Experiment Station Research Reports

In Exp. 1, increasing dietary lysine from .40% to .70% linearly improved ADG, F/G, 10th rib fat depth, and percentage lean in finishing gilts from 200 to 250 lb. Increasing dietary lysine also tended to improve longissimus muscle area. Results from Exp. 2 indicate no improvement in growth or carcass performance of gilts fed greater than .60% lysine. The combined results of Exp. 1 and 2 indicate that finishing gilts from 200 to 250 lb requires between .60% to .70% (18 to 20 g/d) dietary lysine to maximize both growth performance and carcass characteristics.; Swine Day, Manhattan, KS, November 21, …


Determination Of Contract Base Payments To Feeder-Pig Producers (1996), J L. Parcell, Michael R. Langemeier Jan 1996

Determination Of Contract Base Payments To Feeder-Pig Producers (1996), J L. Parcell, Michael R. Langemeier

Kansas Agricultural Experiment Station Research Reports

Risks associated with independent feeder-pig production have prompted producers to seek alternative production and marketing methods. A means of reducing risk has developed through contract feeder-pig producing. Research results indicate that slightly risk-averse producers required contract base payments ranging from $7.50 to $28.50 per head. Strongly risk-averse producers required contract base payments ranging from $2.50 to $17.75 per head. The lower end of the ranges is for a low-profit producer. The upper end of the ranges is for a high-profit producer.; Swine Day, Manhattan, KS, November 21, 1996


Monthly Variation In Hog Carcass Traits (1996), J Mintert, Steven S. Dritz, Ted C. Schroeder, S Hedges Jan 1996

Monthly Variation In Hog Carcass Traits (1996), J Mintert, Steven S. Dritz, Ted C. Schroeder, S Hedges

Kansas Agricultural Experiment Station Research Reports

Little research has been conducted regarding the impact that time of year when hogs are marketed has on various carcass traits. This study examined monthly variation in a variety of hog carcass traits based upon 1995 slaughter summaries provided by a midwestern hog marketing network. Results indicate that carcass traits did indeed vary throughout the 1995 calendar year. However, given that these monthly variations were observed only during one year, it remains to be seen whether they indicate a seasonal relationship that hog producers can expect to see year after year or specific factors operative only in 1995. Additional years …

Explaining Differences In Efficiency Among Farrow-To-Finish Producers (1996), W W. Rowland, Michael R. Langemeier, Allen M. Featherstone, Bryan W. Schurle

Kansas Agricultural Experiment Station Research Reports

To remain competitive, hog operations will need to continue to improve production efficiency and manage costs. Kansas Farm Management Association data from 1992 to 1994 were used to measure technical, economic, and overall efficiency for 43 farrow-to-finish operations in Kansas. On average, the farms had .89 technical, .75 economic, and .67 overall efficiencies. Efficiency was related positively to the number of litters produced and pounds of pork produced per litter. Efficiency was related negatively to percentage of labor hired, feed conversion rates, and capital investment per litter. Pounds of pork produced per litter and feed conversion had the largest impacts …

Influence Of A Probiotic/Trace Mineral Mixture On Growth Performance And Salmonella Choleraesuis Shedding In Nursery Pigs (1996), Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

We tested a probiotic/trace mineral mixture using a bacterial challenge model in high-health status pigs. We examined the influence of the mixture on growth performance, hematologic parameters, haptoglobin concentration, and Salmonella choleraesuis shedding in nursery pigs. A successful model of S. cholereasuis challenge was established. However, the probiotic/trace mineral mixture did not influence growth performance, bacterial shedding, or other parameters examined in this experiment.; Swine Day, Manhattan, KS, November 21, 1996


Determining The Optimal Isoleucine:Lysine Ratio For The 25 To 50 Lb Pig (1996), J R. Bergstrom, J A. Loughmiller, R E. Musser, W B. Nessmith Jr, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Steven S. Dritz Jan 1996

Kansas Agricultural Experiment Station Research Reports

A 21-day growth trial was conducted to determine the isoleucine: lysine ratio necessary to optimize growth performance of the 25 to 50 lb nursery pig reared in a segregated early-weaning (SEW) system. Ten experimental diets, including two levels of lysine (.75% and 1.10% digestible lysine) and five apparent digestible isoleucine:lysine ratios (45, 50, 55, 60, and 65%), were used in a 2 x 5 factorial arrangement. Growth performance was improved by feeding 1.10% rather than .75% digestible lysine. Also, results indicated that the apparent digestible isoleucine requirement for the SEW-reared, 25 to 50 lb pig is approximately .50% of digestible …


Increasing Valine, Isoleucine, And Total Branched Chain Amino Acids For The Lactating Sow (1996), B T. Richert, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen Jan 1996

Increasing Valine, Isoleucine, And Total Branched Chain Amino Acids For The Lactating Sow (1996), B T. Richert, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

One hundred eighty-five sows were used to evaluate effects of the interrelationship between isoleucine and valine on sow and litter performance. Litter weight and weight gain at weaning increased as dietary valine, isoleucine, and total branched chain amino acids increased. Increasing dietary valine increased concentrations of milk DM and fat. Milk DM, CP, and fat increased as dietary isoleucine increased. Both valine and isoleucine increased litter weights. The independent increases in litter weaning weights from adding valine and isoleucine suggest separate modes of action in the lactating sow.; Swine Day, Manhattan, KS, November 21, 1996

Kansas Agricultural Experiment Station Research Reports

A 14-d growth trial was conducted to evaluate effects of increasing isoleucine: lysine ratios on growth performance of the segregated early-weaned pig. Twelve experimental diets included two levels of lysine (1.15%and 1.50% digestible lysine) and six digestible isoleucine: lysine ratios (40, 45,50, 55, 60, and 65% relative to lysine) in a 2 x 6 factorial arrangement. From d 0 to 14, growth performance was improved by feeding 1.50% digestible lysine. A linear improven1ent in growth performance occurred from d 0 to 7 as the isoleucine:lysine ratio increased. Although a significant quadratic response was not observed, little improvement in pig performance …

Kansas Agricultural Experiment Station Research Reports

In Exp. 1, increasing dietary methionine from .12 to .22% (.10 to .20% apparent digestible methionine) in diets containing excess cystine had no effect on ADG, ADFI, 10th rib fat depth, and longissimus muscle area in finishing gilts from 130 to 190 lb. However, increasing dietary methionine tended to linearly improve feed efficiency. In Exp. 2, increasing dietary methionine from .11 to . 17% (. 10 to . 15% apparent digestible methionine) in diets containing excess cystine resulted in linear improvements in ADG, ADFI, and F/G in finishing gilts from 160 to 230 lb. Quadratic improvements were observed for F/G. …

Kansas Agricultural Experiment Station Research Reports

Finishing gilts (initially 163 lb) were fed .58% total lysine (.50% apparent digestible) and total sulfur amino acid (TSAA) concentrations of .26, .285, .31, .335, and .36% (.225 to .325% apparent digestible). These values represent TSAA: lysine ratios of 45, 50, 55, 60, and 65%. Results suggest a linear decrease in ADG and ADFI along with poorer F/G with increasing TSAA levels. However, gilts fed .285% TSAA (50% of lysine) had the best ADG and F/G. No effect was observed on any carcass criteria. Based on the results of this study, the TSAA requirement is not greater than .285% total …

Kansas Agricultural Experiment Station Research Reports

We evaluated the effects of a modified-live virus vaccine for PRRS virus on nursery growth performance. The pigs used in this study were obtained from a herd with substandard nursery growth performance attributed to PRRS virus infection. We failed to detect the presence of active circulating field strain virus in either the controls or vaccinated pigs. However, we did detect a strain similar to the vaccine virus strain on d 34 after weaning in the vaccinated pigs. The vaccinated pigs had poorer growth performance from d 7 to 14 after vaccination and were lighter in weight for the remainder of …

Kansas Agricultural Experiment Station Research Reports

A 14-day growth trial was conducted to determine the interactive effects of ingredient processing and diet complexity on growth performance of segregated early-weaned pigs. Three processing combinations were used with either a simple or complex diet formulation in 2 x 3 factorial arrangement. Diets were pelleted (control); the corn was moist-extruded, then the complete diet pelleted (extruded); or the complete diet was expanded then pelleted (expanded). An interaction was observed between ingredient processing and diet complexity. Pigs fed the control or extruded diets had improved growth performance as diet complexity increased. However, pigs fed the expanded diets showed little response …

The Effect Of Carbohydrate Source And Extrusion Processing On Growth Performance On Segregated Early-Weaned Pigs (1996), K Hongtrakul, J R. Bergstrom, I H. Kim, W B. Nessmith Jr, Robert D. Goodband, Keith C. Behnke, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

A 21-day growth trial was conducted to determine the effect of various carbohydrate sources with or without moist extrusion processing on growth performance of segregated early-weaned pigs. Treatments included five different carbohydrate sources (corn, corn starch, rice, wheat flour, and grain sorghum) with or without moist extrusion processing in a 2 x 5 factorial arrangement. No interactions were observed among carbohydrate sources and extrusion processing. Growth performance was not improved by extrusion processing. Surprisingly, pigs fed corn had poorer growth performance compared to those fed other carbohydrate sources. These results suggest that corn starch, rice, wheat flour, and grain sorghum …
