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

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 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

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

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

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 …

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

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

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 …

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

Comparisons Among Crossbred Beef Cattle For Growth And Carcass Traits, 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 …

Fate Of Fumonisins In Cattle Fed Contaminated Feed, R.A. Thakur, N. Wallace, J. Scott Smith, Tiruvoor G. Nagaraja Jan 1996

Fate Of Fumonisins In Cattle Fed Contaminated Feed, R.A. Thakur, N. Wallace, J. Scott Smith, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

Fumonisins are water-soluble carcinogenic mycotoxins produced by many species of Fusarium molds. Fumonisins occur widely in corn, making them a problem in corn-based feed. Their toxicity has been established in many species. However, their effects on cattle and the potential of carryover to the human diet through beef has not been studied extensively. A 30-day cattle feeding study was conducted by feeding fumonisin-contaminated corn grits dosed at 400 g/g fumonisin B1 (FB1) and 130 g/g fumonisin B2 (FB2) to 3 steers averaging 480 lb. Premortem analysis involved urinalysis; tests for liver functionality; and analysis of the blood, urine, and feces …

Bacterial Flora Of Liver Abscesses From Feedlot Cattle Fed With Or Without Tylosin, A.B. Beharka, L.H. Carroll, A.P. Raun, S.B. Laudert, J.C. Parrott, Tiruvoor G. Nagaraja, M. M. Chengappa Jan 1996

Bacterial Flora Of Liver Abscesses From Feedlot Cattle Fed With Or Without Tylosin, A.B. Beharka, L.H. Carroll, A.P. Raun, S.B. Laudert, J.C. Parrott, Tiruvoor G. Nagaraja, M. M. Chengappa

Kansas Agricultural Experiment Station Research Reports

Fusobacterium necrophorum was the predominant bacterial isolate from liver abscesses of feedlot cattle fed with or without tylosin. The major difference in the bacterial flora of liver abscesses between cattle groups was the higher incidence of Actinomyces pyogenes in the tylosin-fed cattle. Because the minimum inhibitory concentration of tylosin was not different between bacterial isolates from cattle in the two treatments, we concluded that continuous feeding of tylosin does not induce resistance. The source of A. pyogenes infection and significance of A. pyogenes interaction with F. necrophorum in tylosin-fed cattle are not known.

Effect Of Feeding Rumen-Protected Lysine With Different Levels Of Soybean Meal To Growing Steers, R.H. Wessels, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

To test the efficacy of rumen-protected lysine and methionine, six steers (486 lb) were used in a 6 4 incomplete Latin square design and fed corn-urea diets (85% concentrate) alone or supplemented with 2 or 4% soybean meal to give dietary crude protein levels of 12.5, 13.2, and 14.0% (as fed-basis). Each diet was fed with or without 5 g/day Smartamine-ML (rumen-protected lysine and methionine). Steers were fed to gain 2.6 lb/day. Nitrogen retention increased linearly, from 30.7 g/day (0% soy) to 35.5 g/day (4% soy) as the level of soybean meal and, thus, crude protein, increased in the diet. …

Supplementing Growing Holstein Steers Fed A Corn-Urea Diet With A Mixture Of Essential Amino Acids Increases Performance, R.H. Wessels, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Six ruminally cannulated Holstein steers (550 lb) implanted with Revalor-S were infused abomasally with water or a mixture of six amino acids in a crossover experiment (two 14-day periods) to evaluate effects on nitrogen balance. The mixture was comprised of amino acids that potentially may be limiting in lightweight steers, namely (g/day): lysine (5.3), methionine (3.3), threonine (3.2), tryptophan (1 .0), histidine (2.1), and arginine (5.5). Steers were fed at levels just below ad libitum intake. The diet contained 86% rolled corn, 10% prairie hay, 3% mineral and vitamin premixes, and 1% urea (as-fed). Amino acid infusion increased nitrogen retention …
