Influence Of Implanting Grazing Steers With Ralgro® Or Synovex-S® Followed By Synovex® Plus™ Or A Ralgro®/Synovex® Plus™ Reimplant Program In The Feedlot On Pasture/Finishing Performance And Carcass Merit (1997), T.R. Fankhauser, Gerry L. Kuhl, D.D. Simms, Gerald L. Stokka, James S. Drouillard, Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

In an 84-day pasture/132-day finishing study using 480 crossbred steers (675 lb), Ralgro® increased (P<.05) pasture gains 9.3% compared to nonimplanted controls. Gains of Synovex-S®-implanted steers were intermediate. Pasture treatments were split into two finishing-phase implant treatments: Synovex® Plus™ or initial Ralgro with a Synovex Plus reimplant on day 56. No interactions occurred between pasture and finishing implants with respect to finishing performance or carcass traits. Steers on the Synovex Plus treatment gained 11.7% faster and 7.9% more efficiently (P<.01) during the first 56 days of the finishing phase than the Ralgro-implanted steers. However , when those steers were reimplanted with Synovex Plus, they gained 22.2% faster and 21.1% more efficiently (P<.01) during the last 76 days. Over the entire 132-day finishing phase, the feedlot reimplant program improved rate (4.0%; P<.06) and efficiency (7.5%; P<.01) of gain compared to Synovex Plus alone. Overall , gains and intakes during the finishing phase were similar for all pasture implant treatments. However, control pasture steers were 4.5% more efficient (P<.08) than Ralgro and Synovex steers during the finishing phase. Neither pasture or finishing implant treatment influenced carcass traits. This study indicates that implanting during grazing may reduce feed efficiency during the finishing phase, especially when a feedlot reimplant program is not used. However, this finding disagrees with several previous research studies where pasture implantation had no effect on feedlot performance.

A Survey Of Purchasers Of Wheat Middlings: Storage, Feeding Practices, And Problems (1997), G.W. Warmann, Keith C. Behnke, Dale A. Blasi Jan 1997

A Survey Of Purchasers Of Wheat Middlings: Storage, Feeding Practices, And Problems (1997), G.W. Warmann, Keith C. Behnke, Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

We surveyed 290 purchasers of wheat middlings (WM) from a single flour mill located in central Kansas to characterize the incidence of transport and storage problems and to determine intended animal us e and method of feeding. Over 30% of the 106 respondents had encountered storage problems with WM; mold, spoilage, and bridging in the storage structure were the most common. Over 75% of the respondents who reported no storage problems purchased WM during the winter months and avoided WM purchases at other times, especially during the summer.

Effect Of Revalor-G On The Performance Of Stocker Heifers Grazing Irrigated, Smooth Bromegrass Pasture For A Full Season (1997), Gerry L. Kuhl, M.D. Reynolds, Robert T. Brandt Jr., Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

A 150-day field study was conducted to evaluate single vs. reimplant strategies for stocker heifers grazing irrigated smooth bromegrass . Three hundred forty-three previously nonimplanted British crossbred heifers averaging 494 lb were assigned to one of seven treatments: 1) no implant-control (NC), 2) Revalor-G® (REVG), 3) Ralgro® (RAL), 4) Synovex-H® (SYNH), 5) REVG/REVG, 6) RAL/RAL, and 7) SYNH/SYNH. Reimplanting (Treatments 5, 6 , and 7) was done on day 75 of the trial. In the first 75 days, all implants increased (P<.05) average daily gain (ADG) compared to NC. For the last 75 days (days 75 through 150), heifers implanted with REVG, REVG/REVG, RAL/RAL, and SYNH gained faster (P<.05) than NC or those implanted with RAL, and SYNH/SYNH. No significant differences occur red among the latter three treatments. Over the entire trial, there was no advantage to reimplanting heifers with REVG or RAL. SYNH/ SYNH heifers gained less (P<.05) than their single -implanted counterparts.

Effects Of Dietary Energy Density And Lysine:Calorie Ratio On The Growth Performance Of Growing Pigs And Subsequent Finishing Performance (1997), J W. Smith Ii, P R. O'Quinn, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

One hundred twenty crossbred gilts were used in a growth trial to evaluate the effects of increasing dietary energy density and lysine:calorie ratio on growing pig growth performance and subsequent finishing performance. Feeding 3% choice white grease and 3.45 g lysine:Mcal ME maximized growth performance of growing gilts. Choice white grease additions and increasing lysine:calorie ratio during growing (65 to 160 lb) did not affect carcass back fat or loin depth at 235 lb.; Swine Day, Manhattan, KS, November 20, 1997

Effects Of Low-Protein, Amino Acid-Fortified Diets, Formulated On A Net Energy Basis, On The Growth Performance And Carcass Characteristics Of Finishing Pigs (1996), J W. Smith Ii, P R. O'Quinn, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen Jan 1997

Effects Of Low-Protein, Amino Acid-Fortified Diets, Formulated On A Net Energy Basis, On The Growth Performance And Carcass Characteristics Of Finishing Pigs (1996), J W. Smith Ii, P R. O'Quinn, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Two hundred eighty-eight gilts were used to determine the effects of corn-soybean meal or low-protein, amino acid-fortified diets, formulated on a net energy (NE) basis on growth perforn1ance and carcass characteristics. Pigs fed high NE grew faster from 105 to 165 lb. However, pigs fed diets with intact protein grew faster and more efficiently during the finishing period and for the entire trial than those fed low protein, amino acidfortified diets. Carcass data revealed that pigs consuming high NE were fatter and had lower percentage lean than pigs consuming low NE. Additionally, longissimus muscle area tended to be greater in …

Effects Of Starch Gelatinization On Weanling Pig Performance (1997), K Hongtrakul, J R. Bergstrom, W B. Nessmith Jr, I H. Kim, Robert D. Goodband, Keith C. Behnke, Jim L. Nelssen, Michael D. Tokach Jan 1997

Effects Of Starch Gelatinization On Weanling Pig Performance (1997), K Hongtrakul, J R. Bergstrom, W B. Nessmith Jr, I H. Kim, Robert D. Goodband, Keith C. Behnke, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

Two hundred and ten weanling pigs were fed diets containing nonextruded corn (14.5% gelatinization; control) or corn that was extruded to provide 38.7%, 52.7%, 64.4%, or 89.3% starch gelatinization in the complete diet. With increasing gelatinization, ADG and ADFI decreased and then increased. but apparent digestibility of DM, CP, and energy increased then decreased. These results suggest that the degree of starch gelatinization has an inconsistent effect on weanling pig performance.; Swine Day, Manhattan, KS, November 20, 1997

Effects Of Sorghum Genotype And Processing Method On Production Characteristics And Growth Performance Of Nursery Pigs (1997), J R. Froeschner, Z J. Cheng, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Three sorghum varieties that varied in starch composition were fed to Phase II and Phase III pigs to determine if feeding sorghum high in waxiness provided a benefit. In addition, each variety was fed as a meal, standard pellet, and an expanded pellet. As level of waxiness increased, pellet durability index increased numerically and the amount of fines produced decreased numerically. In addition, thermal processing of the diets increased the feeding value. Sorghum genotype had little effect on pig performance.; Swine Day, Manhattan, KS, November 20, 1997

Effects Of Source And Level Of Added Chromium On Growth Performance Of Starter Pigs (1997), P R. O'Quinn, R E. Musser, K Q. Owen, S A. Blum, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

A 35-d growth trial was conducted with conventionally weaned nursery pigs to evaluate the efficacy of supplemental chromium (Cr) as either chromium nieotinate (CrNic) or chromium picolinate (CrPic). Neither source nor level of supplemental Cr had any effect on weanling pig growth performance or immune status. Equal levels of CrNic and CrPic produced similar results, except that pigs fed CrPic had higher serum Cr concentrations than pigs fed CrNic. These data suggest no beneficial responses to supplemental CrNic or CrPic in nursery pig diets.; Swine Day, Manhattan, KS, November 20, 1997

Kansas Agricultural Experiment Station Research Reports

The objective of this experiment was to study the influence of tetracycline on the transfer of antibiotic resistance in an in vivo swine model experimentally infected with antibiotic-resistant and antibiotic susceptible Salmonella spp. Tetracycline reduced the amount and duration of shedding of tetracycline- susceptible Salmonella. However, tetracycline had no effect on shedding of resistant Salmonella. We also have evidence that resistance was transferred from the resistant to the susceptible strain of Salmonella.; Swine Day, Manhattan, KS, November 20, 1997

Trends In The Swine Industry: Operations And Marketings (1997), J L. Parcell, Kevin C. Dhuyvetter

Kansas Agricultural Experiment Station Research Reports

Trends in the size of swine operations in Kansas and the V. S. are toward fewer and larger operations. The number of operations in Kansas and the U.S. continues to decline; however, the number of hogs marketed has increased because of an increase in operation size. Kansas producers have increased operation size at a slower rate compared to U.S. producers. Kansas ranks tenth nationally in hogs marketed. A migration of swine production from eastern, central, and northern Kansas to southwest Kansas has occurred in the past 5 years.; Swine Day, Manhattan, KS, November 20, 1997

Historical Economic Returns To Alternative Swine Enterprises In Kansas (1997), R Jones, Michael R. Langemeier

Kansas Agricultural Experiment Station Research Reports

This study examines historical net returns to average Kansas swine producers over the past 16 years. Swine production has been a profitable enterprise. As expected, average returns per head have been higher for farrow-to-finish producers than for feeder pig finishers, and farrow-to-finish producers have nearly always been able to at least cover variable costs of production.; Swine Day, Manhattan, KS, November 20, 1997

Ultrasound Versus Convection Cooking Of Beef Longissimus And Pectoralis Muscles (1997), F.W. Pohlman, J.F. Zayas, Michael E. Dikeman, John A. Unruh Jan 1997

Ultrasound Versus Convection Cooking Of Beef Longissimus And Pectoralis Muscles (1997), F.W. Pohlman, J.F. Zayas, Michael E. Dikeman, John A. Unruh

Kansas Agricultural Experiment Station Research Reports

Longissimus and pectoralis muscles were removed from 10 steer carcasses at 4 days postmortem , aged for 14 days at 4 ÌŠF, then assigned to either ultrasound (ULS) or convection (Conv) cooking to either 144 or 15 8 ÌŠF internal temperature. Ultrasound cooking was faster (P<.05), had greater (P<.05) moisture retention and less (P<.05) cooking loss, and used less energy (P<.05). It also produced muscle samples that required less (P<.05) peak force to shear than those from Conv cooking and resulted in superior (P<.05) myofibrillar tenderness. No significant interactions occurred among cooking method, muscle, or endpoint temperature. As expected, longissimus (ribeye) muscles cooked faster (P<.05) and required less (P<.05) energy and were superior (P<.05) in instrumentally measured texture and sensory tenderness than pectoralis muscles. Cooking to 158EF caused greater (P<.05) moisture and cooking losses, required more (P<.05) time and energy, and degraded (P<.05) instrumental textural and sensor y characteristics. Ultrasound offers a new cooking mode that could increase cooking speed, improve energy efficiency and improve some textural characteristics, compared to conventional cooking.

In experiment 1, 71 calves were blocked by weight and allotted to one of four individually fed treatments: 1) control supplement (2 lb grain creep ) (CS), 2) CS + .27 mg selenium + 500 IU vitamin E, 3) CS + 9.1 mg copper, and 4) combination of treatments 2 and 3. In experiment 2, 80 crossbred beef calves were blocked by weight and allotted to 5 individually fed …

Forage protein characteristics in four grasses were evaluated by the nylon bag method. All of the forages used (Bermudagrass hay, brome hay, forage sorghum hay, and prairie hay) were of relatively low quality, except the Bermudagrass, which was of average quality. The forages differed in the size of different protein fractions and in the rate and extent of protein degradation. Predicted extent of ruminal protein degradation (i.e., ruminal protein availability) was lowest for prairie hay, intermediate for Bermudagrass and forage sorghum hay, and highest for the brome hay.
