Effects Of Two (Diptera: Culicidae) Mosquito Control Agents On Growth And Reproduction Of Red-Winged Blackbirds (Agelaius Phoeniceus), Joann M. Hanowski, Gerald J. Niemi, Ann R. Lima, Ronald R. Regal

Journal of the Minnesota Academy of Science

We compared red-winged blackbird (Agelaius phoeniceus) reproductive success and nestling growth in 1988 in 10 wetland site treated with methoprene and 10 sites treated with Bacillus thuringiensis israelensis (Bti) to 30 sites that had never received any mosquito (Diptera: culicidae) control treatment. No differences were detected between reference and treatment sites for clutch size, egg volume, growth rates, or fledge weight. The probability that an egg survived to the nestling stage was greater in methoprene-treated than reference sites. No other differences were detected among sites for reproductive success estimated using the Mayfield method. We conclude that treatment of the wetlands …

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 Jan 1997

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 Jan 1997

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.
