Use Of Video Image Analysis, Ribeye Grids, And Linear Ribeye Measurements To Predict And Compare Ribeye Areas From Carcass Left And Right Sides, A.T. Waylan, R.E. Campbell, John A. Unruh
Kansas Agricultural Experiment Station Research Reports
Ribeye tracings from 265 beef carcasses were used to compare ribeye areas from right and left sides. When video image analysis (VIA) was used to determine ribeye area, no difference (P=.48) was observed between right and left sides. However, when ribeye area was determine d by using USDA grids, those on the left side were slightly larger (P<.01) than those on right side. This difference is negligible considering the wide rang e in variation (SD=.68 in2) between right and left side ribeye areas. Ribeye area correlations between VIA and grid result s were high for both right (.96) and left (.95) sides. Linear measures (length, midwidth, and widest width) of ribeyes predicted ribeye area with reasonable accuracy ( R2=.90 and .91). These methods provide several options to determine ribeye area. However, data collectors need to realize that the difference between right and left side ribeye areas may be a greater variable than the sensitivity of the method used.
Delineation Of Geographic Markets For Fed Cattle, Ted C. Schroeder
Delineation Of Geographic Markets For Fed Cattle, Ted C. Schroeder
Kansas Agricultural Experiment Station Research Reports
Determining the extent of geographic markets for fed cattle is important for monitoring performance of the industry. The ability of packing plants to influence prices is determined in part by their ability to segment the market for fed cattle and isolate themselves from plants in other regions. This study analyzed transaction data from 43 U.S. steer and heifer slaughter plants collected by the Grain Inspection Packers and Stockyards Program for approximately a 1-year period during 1992-93. Beef packers procured an average of 64% of their cattle within 75 miles of packing plants, 82 % within 150 miles, and 92% within …

Effect Of Revalor-G On The Performance Of Stocker Heifers Grazing Irrigated, Smooth Bromegrass Pasture For A Full Season, 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.

Kansas Agricultural Experiment Station Research Reports
Thirteen ruminally fistulated steers were used to determine the effect of carbohydrate (CHO) source and degradable intake protein (DIP) on intake and digestion of tallgrass-prairie hay. In general, DIP supplementation had positive effects on intake and digestion, although response varied somewhat with CHO source. Increasing the amount of supplemental CHO generally decreased hay intake, but effects on digestion were dependent on CHO source.

Estimating The Undegradable Intake Protein Content Of Two Forages By Different Commercial Proteases, I.E.O. Abdelgadir, R.C. Cochran, E.S. Vanzant, Evan C. Titgemeyer
Kansas Agricultural Experiment Station Research Reports
We evaluated the potential of several commercially available proteases for use in predicting the undegradable intake protein (UIP) concentrations o f alfalfa and prairie hay. Protease s differed in their estimates o f the rate of forage protein breakdown an d the amounts of different forage protein fractions . At least one protease appeared to yield acceptable predictions of UIP via a short-term, single time-point assay. Assays of this type deserve further consideration for commercial application.

Kansas Agricultural Experiment Station Research Reports
A 35-d experiment was conducted to compare the effects of increasing spray-dried animal plasma and a high protein whey concentrate (73% CP) on starter pig performance. Spray-dried animal plasma and whey protein concentrate replaced dried skin1 milk on an equal lysine basis. Pigs fed increasing spray-dried animal plasma protein had increased ADG and ADFI from d 0 to 7 after weaning, but not for any other period in the study. Increasing whey protein concentrate had no effect on growth perforn1ance in relation to the pigs fed dried skim milk.; Swine Day, Manhattan, KS, November 20, 1997

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

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

Kansas Agricultural Experiment Station Research Reports
Determining the value of silage saved by effectively sealing a horizontal silo requires only a few simple calculations, but it is still a concept that is often overlooked by many livestock producers who store large amounts of silage in that manner. Kansas produces about 3.0 million tons of silage annually, primarily from corn and sorghum. A majority of this silage is made and stored in either bunker, trench, or "drive-over" pile silos . Only 20 to 30% of these silos are sealed after filling. Producers who do not seal need to take a second look at the economics of this …

Kansas Agricultural Experiment Station Research Reports
A total of 307 sows was used to determine the effects of adding 50 ppm of L-carnitine in gestation and lactation diets on sow and litter performance. Addition of 50 ppm L-carnitine in gestation increased both total litter (34.1 vs 32.1 lb) and pig (3.48 vs 3.27 lb) birth weight. Litter weaning weights increased (99.03 vs 90.71 lb) when sows were fed added L-carnitine during gestation. Sows fed added L-carnitine in gestation had increased IGF-I concentrations on d 60 and 90 (71.3 vs 38.0, and 33.0 vs 25.0 ng/ml, respectively). These results suggest that feeding 50 ppm of added L-carnitine …

Productivity has been trending up in the swine industry over the last 15 years. Much of the increased productivity is due to increased pigs/litter and increased market weights. The efficiency of the breeding herd (litters/sow/year) has been trending up in the U.S. but has remained relatively constant in Kansas.; Swine Day, Manhattan, KS, November 20, 1997

Antioxidant Properties Of Liquid Smoke In Precooked Beef Patties, R. Estrada-Munoz, Elizabeth A.E. Boyle, James L. Marsden
Kansas Agricultural Experiment Station Research Reports
Liquid smoke (LS) effectiveness in controlling lipid oxidation and warmed-over flavor (WOF) in beef was investigated. Aroma scores, "α-thiobarbituri c acid (TBA) numbers, and pH values were lower (P<.05) in LS-treated beef patties than in patties without LS. LS has useful antioxidative properties in precooked ground beef patties at the normally recommended percentage of 1.5%. That should reduce undesirable flavor development and product loss.

Kansas Agricultural Experiment Station Research Reports
Agronomic and silage quality traits were measure d for 37 forage sorghum cultivars and three grain sorghum hybrids. The 1995 growing season was characterized by above average rainfall in the spring and early summer, and a hard freeze on September 22. At the time of the freeze, 20 cultivars had reached the early-milk to early-dough stage, 12 were in the bloom stage, and the remaining eight were still in the early- to late-boot stage . The late planting date and low plant populations resulted in below-normal whole-plant D M and grain yields. Plant height s for the grain sorghums were …

Kansas Agricultural Experiment Station Research Reports
This research was designed to develop a set of prediction equations to measure nutrient composition of Kansas sorghum silages using both a portable and a research type near-infrared spectrometer (NIRS). A robust set of equations for dry matter, crude protein, neutral detergent fiber, and acid detergent fiber was developed for a wide range of sorghum phenotypes . NIRS analysis of sorghum silages is feasible with both a tilting filter (portable) and research instrument with a grating monochrometer.

Kansas Agricultural Experiment Station Research Reports
Animal characteristics and sale price data for 1651 bulls sold at 26 Kansas purebred beef sales during 1993 were collected and analyzed to determine which factors affected price differentials for beef bulls. Bull sale price varied, from $650 to $20,000 per head. Regression analysis was used to determine the price differential associated with bull traits and marketing factors. Black bulls in the Simmental, Gelbvieh, and Limousin breeds brought premium s of 15% to 53% compared to their nonblack peers. Conformation, disposition , and muscling affected sell prices. Bulls with lower birth weights and birth weight expected progeny differences (EPD) brought …

Kansas Agricultural Experiment Station Research Reports
In October, 1995, 3,565 head of freshly weaned, British-breed calves were received into a weaning facility in southwest Nebraska. Calves were determined to be preconditioned if they had received both viral an d Pasteurella vaccines prior to weaning (PREWEAN; n = 2,315), and all other calves were considered to have no preconditioning (CRTL; n = 1,250). Cattle were processed within 24 hours of arrival, and booster vaccinations were given when appropriate. Average days on feed at the weaning facility were similar between PREWEAN and CTRL calves (52.4 and 50.3 days, respectively), but average daily gain (2.24 vs 1.87 kb) and …
