Determining The Optimal Isoleucine:Lysine Ratio In Diets For The Segregated Early-Weaned Pig, 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
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 …
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
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 …
Effects Of High Oil Corn And Fat Level On Growth Performance Of Nursery Pigs (1996), J R. Bergstrom, C J. Samland, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband
Effects Of High Oil Corn And Fat Level On Growth Performance Of Nursery Pigs (1996), J R. Bergstrom, C J. Samland, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband
Kansas Agricultural Experiment Station Research Reports
Two studies were conducted to evaluate the effects of adding high oil corn to nursery diets as compared to other sources of fat. The results of both studies suggest that addition of fat to the nursery pig diet, regardless of the source, has no significant influence on growth performance until late in the nursery phase.; Swine Day, Manhattan, KS, November 21, 1996

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

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

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, …
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
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, …

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

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

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

Kansas Agricultural Experiment Station Research Reports
Average daily gain; ADFI; F/G; dressing percentage; tenth rib fat thickness and depth; and color, firmness, and marbling of the longissimus muscle were not influenced by omitting the vitamin and(or) trace mineral premixes from diets during finishing (154 to 247 lb). Thus, omitting vitamin and trace mineral premixes can decrease diet costs without decreasing performance or meat quality of high-lean pigs.; Swine Day, Manhattan, KS, November 21, 1996

The Impact Of Selected Hog Carcass Traits On Prices Received (1996), J Mintert, Steven S. Dritz, Ted C. Schroeder, S Hedges
Kansas Agricultural Experiment Station Research Reports
Hog producers can control the quality of the hogs they market. Through genetic selection and management, producers can have a large impact on hog carcass characteristics such as weight, backfat depth, and loin depth. Determining how much emphasis to place on changing or managing various carcass traits requires knowledge of the trait's value to the individual producer. Results from this study provide information on expected changes in price at one major midwestern packer associated with changes in carcass weight, backfat depth, and loin depth. Number of hogs marketed in each group did not affect net carcass value. However, these results …

Kansas Agricultural Experiment Station Research Reports
Omitting the vitamin and trace mineral premixes and(or) adding 2/3 less supplemental inorganic phosphorus source (from .55% down to .40% total P) to diets during late finishing (191 to 265 lb) had no effect on growth performance, carcass characteristics, or muscle quality in high-lean pigs. Thus, this concept can be used to decrease the cost of feeding terminal-cross pigs to heavy weights, while decreasing excretion of minerals from intensive swine operations.; Swine Day, Manhattan, KS, November 21, 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 …

Kansas Agricultural Experiment Station Research Reports
This study analyzes recent changes observed in pork, farm-to-wholesale and wholesale-to-retail, marketing margins. Although the inflation-adjusted, farm-to-wholesale margin has declined over the last 25 years, the wholesale-to-retail margin has increased. Pork producers need to know why these trends have occurred so they better understand pork marketing margin determinants as they develop policy positions and consider vertical marketing alliances.; Swine Day, Manhattan, KS, November 21, 1996

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 …

Kansas Agricultural Experiment Station Research Reports
Diets that had been processed using standard, long-term, and expander (high shear) conditioning tended to support greater ADG than an unconditioned meal control diet. Pelleting was necessary to maximize efficiency of growth, but only with standard and long-term conditioning. Indeed, the best efficiencies of gain were for pigs fed the expander processed diets, with no additional benefits from pelleting the expanded mash.; Swine Day, Manhattan, KS, November 21, 1996

Kansas Agricultural Experiment Station Research Reports
Pellet size (i.e., 3/32 in., 5/32 in., 5/16 in., and 1/2 in. diameter) had little effect on growth performance during the early stages (d 0 to 5) of the nursery phase. However, the 5/32 in. diameter pellets supported the best efficiencies of gain during the overall nursery (d °to 29) and finishing phases.; Swine Day, Manhattan, KS, November 21, 1996
