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

Futures Contracts For Milk: How Will They Work? (1996), Bob Cropp Jan 1996

Futures Contracts For Milk: How Will They Work? (1996), Bob Cropp

Kansas Agricultural Experiment Station Research Reports

The two new milk futures contracts offer dairy farmers and other buyers and sellers of milk and dairy products additional opportunities to manage price risk in an increasingly volatile milk price environment. The availability of these risk management tools is especially important given the market-oriented direction of federal dairy policy. The CSCE and CME contracts differ somewhat in their specifications. Potential hedgers will need to evaluate which offers the best opportunity to lock in prices. Hedgers also should look at the cheese and nonfat dry milk contracts in determining the most appropriate risk management strategy. Strategies may involve using more …

Always consult your veterinarian when making vaccination decisions. The most common errors are failing to give booster immunizations and doing so at the incorrect time. Animal comfort is a greater determinant of production than vaccinations, and to receive the full benefits of nutrition, genetic, and management programs, cow comfort must be maximized. This does not lessen the need for balanced rations that allow the immune system to respond efficiently to vaccines. More is not necessarily better. The best vaccination program for a dairy includes vaccines for the most probable infectious pathogens possibly found in the herd. This combination is different …

Factors Affecting Titratable Acidity In Raw Milk (1996), Karen A. Schmidt, J. Stupar, John E. Shirley, S. Adapa Jan 1996

Factors Affecting Titratable Acidity In Raw Milk (1996), Karen A. Schmidt, J. Stupar, John E. Shirley, S. Adapa

Kansas Agricultural Experiment Station Research Reports

The value of titratable acidity (TA) as an indicator of raw milk quality has been challenged recently, because milk is refrigerated within minutes after it leaves the cow until it reaches the consumer. Also, high milk protein may interfere with the test or confer falsely high TA values. Samples of milk containing 3.8% protein were used to examine the impact of protein on TA. The effects of milk age and bacterial counts also were investigated. Titratable acidity increased as milk protein content increased but the influence of bacterial populations and age were much more dramatic. As bacterial counts increased, TA …

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 …

Effect Of Increasing Urea Level In Protein Supplements On Performance By Beef Cows Consuming Low-Quality Tallgrass-Prairie Forage, H.H. Köster, R.C. Cochran, E.S. Vanzant, K. C. Olson, Timothy J. Jones, Evan C. Titgemeyer Jan 1996

Effect Of Increasing Urea Level In Protein Supplements On Performance By Beef Cows Consuming Low-Quality Tallgrass-Prairie Forage, H.H. Köster, R.C. Cochran, E.S. Vanzant, K. C. Olson, Timothy J. Jones, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Ninety pregnant Angus Hereford cows consuming low-quality, tallgrass-prairie hay were used to evaluate the influence of changing the amount of supplemental degradable intake protein (DIP) derived from urea on body weight and body condition changes, pregnancy rate, and calf performance. Supplemental treatment groups were: 0, 20, and 40% of the supplemental DIP from urea. Supplements were formulated to contain 30% CP . When sufficient DIP was offered to prepartum cows to maximize DOMI, urea could replace up to 40% of the DIP in a high-protein (30%) supplement without causing problems of supplement palatability. However, trends in body weight and condition …

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.

The Effect Of Implants On Gain Of Steers And Heifers Grazing Native Grass, F.K. Brazle Jan 1996

The Effect Of Implants On Gain Of Steers And Heifers Grazing Native Grass, F.K. Brazle

Kansas Agricultural Experiment Station Research Reports

Four trials were con ducted to determine the effect of different implants on steers and heifers grazing native grass pastures for different lengths of time. In addition, two groups of steers were followed through a feeding period to determine if previous implanting had a residual effect on gain. The implanted (Ralgrofi, Ralgrofi Magnum , Synovex Sfi) steers gained faster than the controls; however, no differences in gain occurred among implants. In the finishing group that went on grass at 687 lb, implants had no effect on subsequent feedlot gain. In the second group (on grass at 569 lb and grazing …

Effect Of Feeding Rumen-Protected Lysine With Different Levels Of Soybean Meal To Growing Steers, R.H. Wessels, Evan C. Titgemeyer Jan 1996

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. …

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

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 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 …
