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

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

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 …

Kansas Agricultural Experiment Station Research Reports

A 21-day growth trial was conducted to determine the threonine: lysine ratio necessary to optimize growth performance of the 25 to 50 Ib pig reared in a high-health, segregated early-weaning (SEW) system. Ten experimental diets, including two levels of lysine (.75% and 1.10% apparent digestible lysine) and five apparent digestible threonine:lysine ratios (40, 47.5, 55, 62.5, and 70%), 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 threonine requirement for the SEW:-reared, 25 to 50 lb pig is approximately 55% of digestible …

Dietary Total Sulfur Amino Acid Requirement For Optimal Growth Performance And Carcass Characteristics In Finishing Gilts (1996), J A. Loughmiller, Michael D. Tokach, Evan C. Titgemeyer, I H. Kim, J R. Bergstrom, J W. Smith Ii, Robert D. Goodband, Jim L. Nelssen Jan 1996

Dietary Total Sulfur Amino Acid Requirement For Optimal Growth Performance And Carcass Characteristics In Finishing Gilts (1996), J A. Loughmiller, Michael D. Tokach, Evan C. Titgemeyer, I H. Kim, J R. Bergstrom, J W. Smith Ii, Robert D. Goodband, Jim L. Nelssen

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 …

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 …

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, …

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 …

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 …

Financial Performance Measures For Kansas Beef Cow Farms (1996), Michael R. Langemeier Jan 1996

Financial Performance Measures For Kansas Beef Cow Farms (1996), Michael R. Langemeier

Kansas Agricultural Experiment Station Research Reports

Financial performance measures assist managers in making strategic plans and tracking progress in relationship to a farm's goals. Kansas Farm Management Association data were used to compute average financial performance measures by herd size for beef cow farms. Farms with over 200 cows derived a larger percent of their income from beef cow production, tended to be large r in terms of gross farm income and total assets, were more profitable, and had lower debt ratios. Differences in financial performance among beef cow farms suggest that comparisons should be made only with herds that are similar in size.

Comparisons Among Crossbred Beef Cattle For Growth And Carcass Traits (1996), K.M. Andries, R.R. Schalles, D.E. Franke, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Data from 5 years of a long-term, rotational crossbreeding project were used to compare breeds for growth and carcass traits. The traits of interest were direct and maternal birth and weaning weights, gain on feed, hot carcass weight, ribeye area, marbling score, and slaughter age. Angus, Brahman, Hereford, Charolais, Simmental, and Gelbvieh breeds were involved. Simmental and Gelbvieh were used as terminal breeds, so maternal effects were not calculated for them. Brahman breeding caused an increased direct birth weight of the calves, but the maternal influence of Brahman decreased birth weight. No difference occurred in maternal weaning weight among the …
