Common Black-Headed Gull In Nebraska, Loren Padelford, Babs Padelford

Nebraska Bird Review

About noon on 18 November 1985 B.J. Rose (14937 N St., Omaha, Neb. 68137) saw a gull flying over the Hartford Sand & Gravel Co.'s sandpit lake, a mile north of Venice, Douglas Co. Because of the size and flight pattern he expected it to be a Kittiwake, but when he got the binoculars on it he saw the white wedge along the outer wing, similar to that of a Bonaparte's. However, except for the white outer primaries, the underwings were uniformly dark. It was an adult winter-plumaged bird with a dark spot behind the eye, bill brownish color (not …

1985 Christmas Count

Nebraska Bird Review

The Christmas count includes 101 species, two more than last year, and three species (compared to two last year) were recorded as present during the count period but not recorded on the count day on any count. Two additional localities (Beaver Valley, northwest Boone Co., and Norfolk) brought the total reporting areas to ten. Fourteen species, compared to eighteen last year, were reported from all localities this year. The total investment count this year was 124,642, compared to 345,092 last year and 43,652 in 1983. The Red-winged Blackbird count for Omaha last year was 255,806; this year it was 32. …

Genetic Parameter Estimates For Reproductive Traits Of Male And Female Littermate Swine, R. O. Bates, D. S. Buchanan, R. K. Johnson, R. P. Wetteman, R. W. Fent, L. K. Hutchens

Department of Animal Science: Faculty Publications

Reproductive traits of purebred and crossbred pigs produced in a four-breed diallel mating system using the Duroc, Landrace, Spotted and Yorkshire breeds were collected for five consecutive farrowing seasons (two farrowing seasons/year) beginning in fall 1976. Paternal half-sib heritabilities and genetic correlations for testicular traits (120 boars from 36 sires), serum testosterone (TE) and luteinizing hormone (LH) concentrations before and after treatment with gonadotropin releasing hormone (GnRH; 131 boars from 37 sires) and breeding performance traits (151 boars from 38 sires) were estimated. Heritability estimates were generally small to moderate except for sperm/gram testis (SGT), LH concentrations before (LH0) and …

Approximating Prediction Error Variances For Multiple Trait Sire Evaluations, S. A. Greenhalgh, R. L. Quaas, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The coefficient matrix for multiple trait (milk, fat, and protein) mixed model equations may be too large to obtain prediction error variances from inverse elements. The commonly used reciprocals of diagonal elements may not be accurate approximations when sire relationships or multiple traits are included since much information is contained in off-diagonal elements. Approximations incorporating increased information from coefficient matrix were compared with actual prediction error variances for multiple trait evaluations for milk, fat, protein, and dollar value (relationships included) of 229 Ayrshire and 248 Brown Swiss bulls. Six approximations were selection index using number of daughter records, inverses of …

Genetic Change In Milk Yield Estimated From Simultaneous Genetic Evaluation Of Bulls And Cows, L. Dale Van Vleck, R. A. Westell, J. C. Schneider

Department of Animal Science: Faculty Publications

Genetic trend for milk yield in the artificially sired Holstein population in the northeastern United States was estimated from solutions for simultaneous genetic evaluations of bulls and cows for an animal model using mixed model equations and including all known relationships among the population by years of birth of 1960 to 1980 (1978 for bulls). First lactation milk records of 1,074,971 artificially sired cows sired by 6000 bulls in 20,065 herds were used. Averages of estimated genetic value by year of birth were similar from solutions after 10, 20, and 30 rounds of iteration of the mixed model equations. The …

South Dakota Custom Feeding Program, J.J. Wagner

South Dakota Beef Report, 1986

Seventy-five preconditioned steer calves representing 14 different owners and a variety of breeds were placed on feed at Longacre Farms. Wentworth. South Dakota. in late November and early December. Average days on feed for the 15 groups of five head was 191 (range 181-2071. Average daily gain was 2.6 lb head per day (range 2.26-2.83). Feed efficiency was 8.2 lb dry matter per pound of gain. Feed cost averaged $35.53 per cwt. gain and nonfeed cost averaged $11.84 per cwt. gain. Average cost of gain excluding interest was $47.37 per cwt. (range 43.16-53.741. Average loss was $85.00 per head (range …

Respiratory Viruses And Antibodies In Preconditioned South Dakota Feeder Calves, M.L. Vickers, R.H. Pritchard

South Dakota Beef Report, 1986

Nasal swabs and blood samples were taken from a t o t a l of 400 calves on a preconditioning evaluation program during 2 years. Fifty calves from each of four South Dakota ranches were divided into preconditioned (PC) and control (CO) groups and sampled both on the ranch and in the feedlot. The preconditioning program followed the recommendations of the South Dakota Beef Cattle Improvement Association and the Extension Service and included vaccination with live virus vaccines for infectious bovine rhinotracheitis (IBR), bovine viral diarrhea (BVD) and parainfluenza-3 virus (PI3). In both years, viruses were isolated from calves on …

Mechanical Treatment And Burning For High Quality Range Forage, F.R. Gartner, E.M. White, R.I. Butterfield

South Dakota Beef Report, 1986

Annual yields of western wheatgrass and total vegetation were increased on a clayey range site following mechanical treatment. More important to the range manager, year t o year variability in forage production was reduced, since soil moisture is stabilized. Yields of Japanese brome, an annual grass, increased from the second through the fourth growing seasons after treatment. Three consecutive years of abundant fall precipitation beginning in 1980 probably triggered seed germination of this invader plant. Prescribed burning of the mechanical range treatments drastically reduced production of Japanese brome and increased forage quality. Both quantity and quality of western wheatgrass increased …

Pricklypear Cactus Control In Western South Dakota, J.R. Johnson, W.L. Tucker, C.E. Stymiest, E.J. Bowker

South Dakota Beef Report, 1986

In a range improvement study, both liquid and pelleted forms of Picloram were effective in controlling pricklypear cactus. Higher rates of chemical hastened control and gave more complete control. At lower rates, cactus was recovering in 1985, the fourth year of study, suggesting that higher rates may be most cost effective. In 1983 noncactus vegetation response was minor. In 1984, "all perennial grass" production increased by more than 50% (312 lb/A) at higher rates of Picloram. Shifts in "cool season" and “warm season" grass components were nonsignificant. In 1985, "cool season grass" was not generally affected by treatments, but "warm …

Effects Of Body Condition On Reproductive Performance Of Beef Cows, P.A. Momont, R.J. Pruitt

South Dakota Beef Report, 1986

Cows were fed differing nutritional levels before and after calving to create a wide range of cow body condition or fleshiness prior t o calving and at the beginning of the breeding season. Cows that were fleshier prior t o calving and when turned on pasture in early May (30 days prior t o the beginning of the breeding season) had a higher cycling rate in early May, June and July. Cows maintaining or increasing slightly in body condition (precalving to early May) tended to have a higher cycling rate during the breeding season than cows which lost body condition …

Effects Of Bull Exposure On Postpartum Intervals And Reproductive Performance In Beef Cows: A Progress Report, C.D. Naasz, H.L. Miller, B.A. Petijean, R.H. Haigh

South Dakota Beef Report, 1986

The effects of bull exposure on time from calving until estrus, conception rates and calving interval were studied for mature beef cows. In the spring of I985 and 1986, cows were randomly allotted to one of two treatment groups. Cows were exposed to vasectomized bulls after calving until breeding or no bull exposure. Cows were heat detected twice daily and blood samples were collected weekly to determine progesterone levels. Heat detection data and progesterone levels indicated onset of estrous cycles occurred earlier in bull exposed cows than non-exposed cows. Conception rates to a timed insemination were not different between the …

Flow Cytometry Evaluation Of Testis And Sperm Cells And Growth Performance Of Bulls Implanted With Zeranol, B.E. Ballachey, H.L. Miller

South Dakota Beef Report, 1986

Effects of preweaning zeranol implants on reproductive function and growth performance were studied in 45 Simmental-Angus bulls. At slaughter, flow cytometry measurements were made on testicular and sperm cells to determine the effects of zeranol on spermatogenesis. There were no differences in weaning or slaughter weights due to implants. Nonimplanted bulls had larger scrota1 circumferences and heavier testicular weights than bulls given one or two implants. The testes of implanted bulls had a lower proportion of developing germ cells relative to nonimplanted bulls. The DNA in sperm from implanted bulls was structurally less stable (i.e., more susceptible to denaturation) than …

Evaluation Of Holstein Bull Sperm Quality By Flow Cytometry, B.E. Ballachey, L.K. Jost, D.P. Evenson

South Dakota Beef Report, 1986

Frozen semen samples from Holstein bulls were measured by the sperm chromatin structure assay (SCSA), a new procedure utilizing flow cytometry for the valuation of sperm quality. Fertility ratings of the bulls were known based on their use in artificial insemination matings. Values obtained by the SCSA were highly correlated (r= -.58 P<.01 with bull fertility ratings. Results of this research indicate the SCSA may be a valuable technique for measurement of sperm cell quality and detection of suboptimal fertility in bulls.

Performance Of Flank Spayed Rumen Autografted Heifers, David L. Whittington

South Dakota Beef Report, 1986

Flank spaying of intact yearling heifers has been a routine procedure for ranchers for several years. Most recently a new technique called rumen autografting has created a lot of interest with ranchers. The technique involves implanting or grafting a small piece of ovarian tissue into the outside lining of the rumen wall. A trial was initiated on May 14, 1986, to compare summer grazing performance of intact flank spayed and rumen autografted heifers with and without a growth implant. The 231 crossbred heifers were randomly allotted to the trial and grazed together for 99 days as one herd. The results …

Effects Of Anabolic Implants On Reproductive Function, Carcass Characteristics And Performance In Postweaned Beef Bulls, S.J. Gordon, H.L. Miller, D.H. Gee, B.A. Petithean

South Dakota Beef Report, 1986

Angus bulls averaging 620 lb were used to study the effects of implants on performance, carcass characteristics and reproductive parameters of intact males. Sixty-six bulls were randomly assigned to four treatments. These treatments were (1) nonimplanted, (2) implanted with 36 mg of Ralgro every 60 t o 70 days, (3) implanted with 220 mg of Synovex-S every 60 t o 70 days, (4) implanted with 24 mg of Compudose every 180 days. Body weights were taken a t the initiation of the trial and every 28 days. Blood samples were collected v i a jugular venipuncture weekly for 9 weeks …

Comparison Of Ralgro, Compudose And Synovex-C Implants On The Growth Performance Of Yearling Steers, D.L. Whittington

South Dakota Beef Report, 1986

Growth response to a single implant was measured in yearling steers grazing native range on two ranches in South Dakota. The steers (724 head) were randomly allotted on each ranch to either a Ralgro, Compudose, Synovex-S or no implant treatment. Implants were administered according to manufacturers recommendations. The yearlings were weighed at the time of implanting in the spring and again 116 t o 148 days later. The ears of the steers receiving Compudose were palpated at the end of the trial to determine retention. The weight advantage of implanted steers over controls ranged from 12.1 t o 30.1 lb. …

Comparison Of Ralgro, Compudose And Synovex-C Implants On The Growth Performance Of Suckling Calves, D.L. Whittington

South Dakota Beef Report, 1986

Growth response to a single implant was measured in suckling steer and heifer calves grazing native range on three ranches in South Dakota, The steers (628 head) were randomly allotted on each ranch to either a Ralgro, Compudose, Synovex-C or no implant treatment. The heifers (714 head) were randomly allotted on each ranch to either a Ralgro, Synovex-C or no implant treatment. Implants were administered according to manufacturers' recommendations. The calves were weighed at the time of implanting and again 163 days later at weaning. The ears of steers receiving a Compudose implant were palpated at weaning to determine retention. …

Effectiveness Of Albendazole Against Parasites And Cow And Calf Performance, H.L. Miller, J. Berthelsen, B.A. Petitjean, R.H. Haigh

South Dakota Beef Report, 1986

Albendazole was utilized in drench and feed additive form to determine its effectiveness against parasite control, cow weight and conception rate and calf weaning weights. Fecal oocyte number was decreased by administration of Albendazole. Calf weaning weights from treated cows were heavier the first two years (14.5 lb for heifers and 10.5 lb for bulls) but decreased the third year (13 lb and 6 lb for heifers and bulls, respectively). Conception rates were similar between the two groups, with the only difference occurring the third year when control cows had a higher conception rate from the second AI than treated …

Determination Of An Optimal Single Dose Of Famphur Administered Om Combination With Levamisole In A Paste Formulation For Grub Control In Beef Calves, H.L. Miller, R.L. Delay, R. Haigh

South Dakota Beef Report, 1986

Eighty-nine bull and heifer crossbred beef calves were utilized in five treatments t o determine the effect of famphur administered as a paste for grub control. The five treatments were (1) experimental paste-0% famphur or control (A), (2) experimental paste-14.4% famphur (B), (3) experimental paste-21.6X famphur (C), (4) experimental paste-28.8% famphur (Dl and (5) Warbex famphur pour-on plus tramisol levamisole gel (El. In all treatments in which famphur was administered (B, C, D and E) effective control of grubs was accomplished. Weight gains were 355, 360, 384, 355 and 356 lb for bulls in groups A, B, C. D and …

The Status Of Horn Fly Resistance In South Dakota, Emmert R. Easton

South Dakota Beef Report, 1986

Ear tags containing the organophosphate insecticide chlorpyrifos have been effective in the control of resistant horn flies in three western South Dakota localities during 1986. Resistance levels of 50-fold to pyrethroid insecticide were detected in horn fly populations at Cottonwood, Colome and Sturgis.

The Release Of Insects Sterilized By Colbalt 60 To Control A Wild Population Of Stable Flies At The Sdsu Beef Cattle And Sheep Nutrition Unit In Brookings, Emmert R. Easton, Michael A. Catangui

South Dakota Beef Report, 1986

Sterile stable flies were released weekly a t the SDSU Beef Cattle and Sheep Nutrition Unit at Brookings from July 24 through September during the summer 1986 season t o eliminate wild populations of insects. Flies that were sterilized were marked with a dye so when recaptured by an insect net or a sticky trap they could be differentiated from wild, normal or fertile flies. A trend toward reduced f l y numbers was observed 3 weeks following the first release. A 1:5 ratio of sterile to wild flies was achieved in 6 weeks.

The Fly Buster. A Combination Mineral Feeder/Spray Device For The Control Of The Horn Fly And The Face Fly On Pastured Cattle, Emmert R. Easton

South Dakota Beef Report, 1986

A combination mineral feeder/spray device was evaluated as a different approach for the suppression of horn and face flies under range conditions in east central South Dakota during the 1985 season. Ravap, Ectrin and Ciovap were applied at the rates of 1.25. .05 and 1.0%, respectively, to Black Angus cattle in three separate pastures with the spray device containing Morton's Farm and Ranch T-M and salt containing iodine and other trace minerals. Cattle in a fourth pasture that were not treated were used as the control. A canister containing Freon 12 acts as a propellant to force the insecticide under …
