Effect Of Cyclosporine On The Rate Of Renal Function Recovery After Renal Transplantation, Francis Dumler

Henry Ford Hospital Medical Journal

To assess the effect of cyclosporine therapy on the rate of renal function recovery after renal transplantation, patients with no clinical evidence of rejection and who were treated with either cyclosporine or azathioprine in addition to steroid therapy were studied (n = 74). Of the patients with immediate renal function (n = 57), those receiving organs from living, related donors had a faster recovery rate of glomerular filtration than patients with cadaveric grafts (azathioprine, 15 ± 2 versus 7 ± 1 mL/min/day, P = 0.0001; cyclosporine, 14 ± 3 versus 6 ± 1 mL/min/day, P = 0.001). Recipients of cadaveric …

Diversity Of Coprophagous Scarabaeidae (Coleoptera) In Grazed Versus Ungrazed Sandhills Prairie In Western Nebraska, Mary Liz Jameson

University of Nebraska State Museum: Entomology Papers

Baited pitfall traps were used to compare the dung-feeding Scarabaeidae (Coleoptera) of a grazed versus an ungrazed sandhills prairie in western Nebraska. Traps yielded 14,832 coprophagous Scarabaeidae over a 4-week sampling period in 1987. Canthon ebenus (Say), C. pilurarius (L.), Onthophagous hecate Panzer, and O. pennsylvanicus Harold were the dominant species on both prairies. The Shannon-Wiener diversity index indicated that diversity was slightly higher on the grazed site, whereas the Margalef diversity index showed the diversities to be nearly the same. Activity and foraging by scarabs (as measured by trapping success) were found to be most closely correlated with temperature …

Changes In Mule Deer Size In Utah, Dennis D. Austin, Robert A. Riggs, Philip J. Urness, David L. Turner, John F. Kimball

Great Basin Naturalist

Trends in age-specific, eviscerated carcass weights were determined for hunter-harvested yearling and two-year-old buck mule deer. Carcass weights declined over an 11-year period from two areas of similar management, but with independenly collected data sets. Carcass weights also declined between the opening and second weekends of the hunt. Management implications are discussed.

Comparison Of Yearling Steer Gains In Early Summer Under Season-Long Native, Season-Long Crested Wheatgrass And June-Deferred Native Grazing Systems, P.S. Johnson, J. J. Wagner, M. J. Goetz, J. Cantrell

South Dakota Beef Report, 1989

Season-long native, season-long crested wheatgrass and June-deferred native grazing systems were compared with regard to average daily gains, gains per acre and total gains. Due to drought conditions, the typical 4-month spring-summer season was reduced to a season of approximately 2 months beginning in June. Few differences were detected between the systems for ADG in each month or over the season. Gains per acre were greatest (P<.05) on crested wheatgrass pastures (33.75 Ib/acre), but no differences were detected between native pastures (1 0.61 -1 6.61 Ib/acre) regardless of whether they had been grazed for 2 months or one (using similar stocking rates). This study indicates that, using weight gain data from 1989 and a 2-month grazing season, the greatest potential gain for the season is realized with a system where cattle graze crested wheatgrass in June and native pastures in July. If this system was applied on 320 acres crested wheatgrass and 640 acres excellent condition native pasture, it would have the potential to produce approximately 23,196 Ib of gain on yearling steers compared with season-long (June-July) production of 9,408 Ib on @I0 acres and 14,112 Ib on 960 acres native pasture.

Effects Of Restricting Intake On Carcass Traits Of Young Steers, R. H. Pritchard, D. H. Gee, M. R. Robbins

South Dakota Beef Report, 1989

Feedlot performance and carcass characteristics were compared when steer calves were fed energy dense diets ad libitum (AL) or restricted (RI) to achieve constant growth rates. AL steers grew more rapidly (P.e.10) than RI steers, 2.93 vs 2.74 Ib per head per day. For the period from 98 days to slaughter (AL = 89 days, RI = 99 days), AL steers consumed more dry matter daily than Rl steers. Restricting intake did not affect feed conversions or total dry matter consumed while in the feedlot. Steers were slaughtered at similar final weights. Intake level did not affect carcass weight, rib …

Estrous Synchronization Of Heifers Using Mga And Prostaglandin: Ranch Results, T. B. Goehring

South Dakota Beef Report, 1989

total of 315 yearling heifers were exposed to an estrous synchronization program which consisted of feeding MGA for 14 consecutive days (.5 mg per head per day), followed by a prostaglandin injection 17 days after the last day of MGA feeding. Two hundred forty-seven (78%) of the heifers were detected in heat and artifically inseminated within 5 days after the prostagllandin injection. Response rate ranged from 75 to 84% between ranches and years.

Comparison Of Melengestrol Acetate And Prostaglandin With Two Injections Of Prostaglandin For Estrous Synchronization In Beef Heifers, H. L. Miller, J. J. Wagner, R. L. Hanson

South Dakota Beef Report, 1989

Crossbred beef heifers were used to compare conception rate when synchronizing estrus with melengestrol acetate (MGA) and prostaglandin or two injections of prostaglandin. Melengestrol acetate was fed to one group of heifers for 16 days and prostaglandin injected 16 days after MGA removal or two injections of prostaglandin given 11 days apart in the other group. The MGA group had a higher conception rate (Pc.05) to timed Al, but there was no difference between the two groups for the breeding season. It appears MGA with prostaglandin results in increased conception to a timed insemination.

Evaluation Of Controlled Release Chromic Oxide Boluses And Alkaline Peroxide Lignin As Marker Methods To Determine Forage Intake Of Grazing Ruminants, P.A. Momont, R. J. Pruitt, R. H. Pritchard

South Dakota Beef Report, 1989

Twenty Hampshire ram lambs used in a digestibility trial were administered controlled release chromic oxide intraruminal boluses to evaluate chromic oxide and alkaline peroxide lignin in combination as potential markers for determining intake of ruminants grazing dormant winter range. Lambs were fed ad libitum mature prairie grass hay and provided .1 Ib crude protein from one of four supplements. The ability to predict fecal output using chromic oxide boluses and diet digestibility using alkaline peroxide lignin were not affected by supplemental treatments. Chromic oxide concentration in the feces was not affected by the time of sampling. The amount of chromium …

Moderate Versus High Protein Diets For Finishing Yearling Steers, J.J. Wagner, R. Hansen

South Dakota Beef Report, 1989

Sixty-four yearling crossbred steers (864 Ib) were utilized to study moderate versus high protein finishing diets. Diets were formulated to contain 11.25 or 12.25% crude protein on a dry matter basis. Differences observed for all performance and carcass traits were not significant. Steers on the 11.25 and 12.25% crude protein diets consumed 22.29 and 22.26 Ib dry matter per head daily, gained 2.83 and 2.90 Ib per head daily and required 7.91 and 7.69 Ib dry matter per pound of gain, respectively. Diets formulated to contain 11.25% crude protein appear adequate for finishing heavy yearlings.

Increasing Profit On Dairy Farms, G R. Olney, Warren Standing

Journal of the Department of Agriculture, Western Australia, Series 4

Farmers continually make decisions on all aspects of their farms that influence profit. For dairy farmers these include the number of cows, calving pattern, level and type of supplementary feeding, area of each pasture type and fodder crop, and the areas for hay or silage, or both. The extent and type of the beef sideline operations also influence the overall profitability of the farm.

The WesternAustralian Dairy Farm Model (WADFM) is a whole farm model developed by the Western Australian Department of Agriculture to help farmers maximise profits by considering all effects of such decisions on the farm.

Formulation Of A Management Scheme For The Swordfish Fishery Of The Eastern Caribbean, Harold F. Upton

Marine Affairs Theses and Major Papers

During the 1983 season, two U.S. longline vessels initiated the first attempts at the commercial exploitation of swordfish in the Eastern Caribbean. In 1986, the number of U.S. vessels participating in the fishery surpassed 40 with landings of nearly two million pounds per season. The sudden influx of participants and technology to the region has resulted in a variety of user conflicts and associated policy issues. Major areas of concern involve the conservation of a heavily exploited resource and the distribution of benefits which accrue from resource exploitation among the resource-adjacent island states and U.S. fishing operations. This study examines …

Changes With Time In The Availability Of Soil Applied Zinc To Navy Beans And In The Chemical Extraction Of Zinc From Soils, J. D. Armour, G. S.P. Ritchie, A. D. Robson

Food Science and Nutrition

The effect of the incubation of zinc (Zn) applied to the soil on Zn uptake and the Zn concentrations in chemical extractants was studied. In a glasshouse experiment using a Zn-deficient gravelly sandy loam, the effect of recently applied Zn was compared with that of Zn incubated with the soil for 15 days at 40°C on growth and Zn uptake by navy beans (Phaseolus vulgaris cv. Gallaroy). At the second harvest (33 days after sowing), the dry weight of shoots of recently applied Zn was consistently higher than that of incubated Zn, except at the highest rate of 1 …
