Using Arsoy™ As A Protein Supplement In Growing Cattle Diets (1999), T.T. Marston, K.K. Kreikemeier, L.E. Wankel, G.L. Huck, T.J. Wistuba Jan 1999

Using Arsoy™ As A Protein Supplement In Growing Cattle Diets (1999), T.T. Marston, K.K. Kreikemeier, L.E. Wankel, G.L. Huck, T.J. Wistuba

Kansas Agricultural Experiment Station Research Reports

Arsoy™ Soybean Feed is a by-product from the manufacture of soy protein isolate. It contains nearly 30% crude protein, but there is little documentation about its feeding value. Therefore, we fed basal growing diets of corn silage and stover to 196 crossbred heifers and supplemented those diets with soybean meal, Arsoy, or a combination of soybean meal and high moisture corn to determine the feeding value of Arsoy. Our results suggest that Arsoy can be substituted for soybean meal in growing cattle diets, without any negative impact on animal performance, dry matter intake, or feed efficiency.

Dehydrated Paunch And Vegetable By-Products For Growing Beef Cattle (1999), T.A. Nutsch, R.D. Hunter, James S. Drouillard Jan 1999

Dehydrated Paunch And Vegetable By-Products For Growing Beef Cattle (1999), T.A. Nutsch, R.D. Hunter, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Crossbred beef heifers (avg wt 653 lb) were used in a feeding experiment to determine the relative feed value of dried paunch content, two separate vegetable processing by-products, and combinations of by-products with dryrolled corn. Consumption of the vegetable byproduct diets, both of which contained a high percentage of fat, was less than expected. Performance of cattle fed the by-product diets was less than that of cattle fed high-energy diets comprised of corn. However, when combined with corn, the vegetable by-product yielded performance similar to that of corn alone.

Effects Of Supplementing Limit-Fed, Wheat Middling-Based Diets With Either Soybean Meal Or Non-Enzymatically Browned Soybean Meal On Growing Steer Performance (1999), C.M. Coetzer, E. Coetzer, R.H. Wessels, James S. Drouillard Jan 1999

Effects Of Supplementing Limit-Fed, Wheat Middling-Based Diets With Either Soybean Meal Or Non-Enzymatically Browned Soybean Meal On Growing Steer Performance (1999), C.M. Coetzer, E. Coetzer, R.H. Wessels, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Seventy two individually fed Angus x Hereford steers (660 lb) were limit-fed, 16.7% CP wheat middling-based diets with 1.9 or 3.8 percentage units of additional CP from either soybean meal (SBM) or non-enzymatically browned soybean meal (NEBSBM). A limitfed, rolled corn-based diet (16.7% CP) also was included. Steers were fed once daily for 70 days at 2.25% of BW. The SBM provided 30% bypass protein, and NEBSBM provided 68%. Average daily gain and efficiency improved linearly with increasing level of NEBSBM (P<.05; ADG=2.482 + .106 (increase in % CP); feed to gain=6.26 - .22(increase in % CP)), but not with increasing levels of SBM. Steers fed the wheat middling diets had lower ADG and efficiency than those fed the corn control diet. These data suggest that bypass protein may be first limiting in highconcentrate, limit-fed growing diets composed predominantly of wheat middlings.

Effects Of Modified Tall Oil And Creatine Monohydrate On Growth Performance, Carcass Characteristics, And Meat Quality Of Growing-Finishing Barrows (1999), P R. O'Quinn, B S. Andrews, J C. Woodworth, Robert D. Goodband, John A. Unruh, Jim L. Nelssen, Michael D. Tokach Jan 1999

Effects Of Modified Tall Oil And Creatine Monohydrate On Growth Performance, Carcass Characteristics, And Meat Quality Of Growing-Finishing Barrows (1999), P R. O'Quinn, B S. Andrews, J C. Woodworth, Robert D. Goodband, John A. Unruh, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

A trial was conducted to evaluate the effects of modified tall oil (MTO; .50% of the diet) and creatine monohydrate (CMH; 25 g/pig/day for 10 days prior to slaughter) on performance, carcass characteristics, and meat quality of finishing barrows. Feeding MTO improved ADG and F/G during the growing phase and improved F/G over the entire trial and during the 10 day CMH loading period. Feeding MTO reduced backfat, but neither CMH nor MTO affected other carcass characteristics or meat quality measures at 24 h postmortem. These data suggest that MTO improves performance and reduces backfat with little effect on meat …

Kansas Agricultural Experiment Station Research Reports

Two studies were conducted to evaluate" the effects of pelleting and pellet conditioning temperature of diets containing 5% spray-dried animal plasma (SDAP) on weanling pig growth performance. In Exp. 1, conditioning temperatures evaluated were 140, 150, 160, and 170°F. In Exp. 2, pellet conditioning temperatures were 140, 155, 170, 185, and 200°F. The results suggest that pellet conditioning temperatures above 170°F decrease weanling pig performance from d 0 to 7 after weaning. Pellet conditioning temperature should not exceed 170OF (exit temperature of 180°F) for nursery diets containing 5% SDAP.; Swine Day, Manhattan, KS, November 18, 1999

Influence Of Dietary Supplementation Of Modified Tall Oil And Vitamin E On Bacon Characteristics (1999), A T. Waylan, P R. O'Quinn, J C. Woodworth, S I. Koo, John A. Unruh, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

Seventy-two crossbred (PIC) barrows were used to determine the influence of feeding modified tall oil (MTO, 0 or .5% of diet) and vitamin E (0, 10, or 50 IU/lb of feed) on bacon quality characteristics. Feeding MTO to pigs during both. the growing and finishing phases increased bacon slice firmness. Feeding swine MTO and vitamin E had minimal effects on bacon production, proximate analysis, and quality traits. Therefore, any of these combinations of MTO with vitamin E can be fed to swine to improve carcass traits without affecting bacon.; Swine Day, Manhattan, KS, November 18, 1999

Kansas Agricultural Experiment Station Research Reports

A trial was conducted to investigate the interactive effects of modified tall oil (MTO) and vitamin E on growth performance and carcass characteristics of growing-finishing barrows. Feeding MTO resulted in increased ADG and improved F/G during the growing phase; otherwise dietary treatment did not affect growth performance during the rest of the trial or overall. Feeding MTO also decreased backfat thickness and increased belly firmness. Increasing vitamin E in diets containing MTO decreased drip loss percentage of the loin. These results indicate that MTO may function as a growth promoter; reduce backfat; and in conjunction with vitamin E, itnprove some …

Effects Of Adding And Removing Dietary Fat On Growth Performance And Carcass Characteristics Of Growing-Finishing Pigs (1999), M De La Llata, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

We conducted an experiment using 1,050 growing-finishing pigs to determine the carryover effect of adding and removing fat in diets. The experimental treatments consisted of six different sequence arrangements of diets without fat or with 60/0 added fat. Diets were fed in four phases. During each phase, ADFI and F/G were decreased when fat was added to the diets. Fat inclusion in the diet during one phase had no influence on the response to fat addition during another phase. Back-fat depth was increased and fat-free lean index decreased when fat was added to the diet during all phases, but not …

Influence Of Dietary Supplementation Of Modified Tall Oil, Chromium Nicotinate, And L-Carnitine On Bacon Characteristics (1999), A T. Waylan, P R. O'Quinn, J C. Woodworth, K Q. Owen, John A. Unruh, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

Eighty crossbred (PIC) gilts were used to determine the influence of feeding modified tall oil (MTO, 0 or .5% of diet), chromium nicotinate (0 or 50 ppb), and L-carnitine (0 or 50 ppm) on bacon quality characteristics. Supplementation of MTO improved bacon slice firmness. Dietary additions of MTO, chromium nicotinate, and L-carnitine to diets for growing and finishing swine had minimal effects on other bacon characteristics. Therefore, producers probably can take advantage of any improvements in production or carcass cutability from these feed supplements without affecting bacon quality.; Swine Day, Manhattan, KS, November 18, 1999

Kansas Agricultural Experiment Station Research Reports

An acute Actinobacillus pleuropneumonia challenge was used to study changes in rectal and radiant surface temperatures over 18 h. From 3.5 to 15 h after challenge, rectal temperatures were elevated in challenged pigs compared to nonchallenged controls. From 6 through 18 h after challenge, infrared surface temperature was higher for challenged pigs versus control nonchallenged pigs. Correlation coefficient analysis indicated that surface temperature and rectal temperature were moderately correlated. These results indicate that infrared thermography will detect changes in body surface temperature associated with the acute phase febrile response and has potential as a diagnostic tool for assessing systemic changes …

Kansas Agricultural Experiment Station Research Reports

Synchronizing ovulation enables dairy producers to inseminate cows by appointment rather than after detected estrus. Three different, timed artificial insemination protocols using different combinations of prostaglandin F2α and gonadotropin-releasing hormone were used to synchronize ovulation in 702 lactating Holstein cows. Cyclicity, pregnancy rate, and embryonic survival rate from each treatment were compared. Our results indicate that all three treatments produced acceptable pregnancy rates in first lactation cows. However, for cows in their second or greater lactation, the treatment using prostaglandin F2α 12 days before the Ovsynch protocol improved pregnancy rates more than the other two.; Dairy Day, 1999, Kansas State …

Kansas Agricultural Experiment Station Research Reports

Time requirements for loading a manure spreader and traveling to and from the field varied from 20 to 30 min per load. However, standardizing the data showed that 5 to 7 min were required per 1,000 gal (9,000 lb). The preliminary results of the time motion data indicate about 30 min per cow per year are required for handling manure from a concrete storage basin. These results were consistent among the four dairies evaluated, even though differences existed in operating procedures. These results enable dairy producers to assess labor and equipment needs for performing the various operations associated with hauling …

Kansas Agricultural Experiment Station Research Reports

Administering progesterone to lactating dairy cows has sometimes proven effective in increasing pregnancy rates. In this study, cows were treated with the Ovsynch protocol in addition to supplemental progesterone given for 7 days between the first gonadotropin- releasing hormone (GnRH) injection and the prostaglandin F2á (PGF2á) injection. Conception rates were greater in lactating Holstein dairy cows receiving exogenous progesterone (62.5%) than in controls treated with only the Ovsynch protocol (35.5%). In addition, progesterone supplementation increased embryo survival between 28 and 56 days of pregnancy.; Dairy Day, 1999, Kansas State University, Manhattan, KS, 1999;

Using The Ovsynch Protocol For Prompt Re-Insemination Of Cows Diagnosed Open At Pregnancy Checks (1999), Jeffrey S. Stevenson Jan 1999

Using The Ovsynch Protocol For Prompt Re-Insemination Of Cows Diagnosed Open At Pregnancy Checks (1999), Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Using the Ovsynch protocol to prepare cows for re-insemination proved to be very effective. Its use guarantees that all cows found open at pregnancy diagnosis are reinseminated promptly within 10 days, and the average pregnancy rate of 28.7% in 136 cows was acceptable. Pregnancy rates were not different whether or not estrus was detected in cows at the timed insemination, but they tended to be greater at second services compared to other repeat services. The Ovsynch protocol is an effective tool to use to ensure prompt re-insemination of open cows.; Dairy Day, 1999, Kansas State University, Manhattan, KS, 1999;

A study was conducted to compare performance, morbidity, retreatment percent, and mortality in stressed heifer calves during the receiving and growing phases after receiving either Pyramid™ MLV 4 or Pyramid™ 4+Presponse® SQ on arrival at a feedlot research facility. Vaccination with Pyramid 4+Presponse SQ (a 4-way viral modified live vaccine with a Pasteurella haemolytica bacterin-toxoid) tended to reduce the incidence of bovine respiratory disease (P=.2) and reduced retreatment rate (P<.06).

The original commercial Steam Pasteurization ™ System (SPS 400) involved a sealable moving car by which carcass sides were carried through the steam chamber at standard line speeds. A second generation "static chamber" system (SPS 400-SC) eliminates the mechanical moving car and has been installed in a large beef slaughter facility. We collected data to verify SPS 400-SC's effectiveness at chamber temperatures from 185 to 205EF in a batch process mode (only test carcasses passing through the unit at variable intervals to facilitate collection of research samples) and at 190EF with the system running continuously. Tissue samples were obtained from …
