Growth Performance For Four Breeds Of Swine: Crossbred Females And Purebred And Crossbred Boars, D. G. Mclaren, D. S. Buchanan, R. K. Johnson

Department of Animal Science: Faculty Publications

Purebred and two-breed cross (F₁) boars were mated to F₁ females to produce all possible three- and four-breed cross pigs involving the Duroc, Yorkshire, Landrace and Spotted breeds. Individual post-weaning average daily gain (ADG), age at 100 kg (AGE) and probed backfat thickness at 100 kg (BE) data were collected on 3,456 pigs. A total of 213 pens with an average of 15.58 pigs per pen was evaluated for post-weaning feed-to-gain ratio (F/G) and average daily feed consumption (ADF). Genotype x environment interactions, specifically breed x year-season farrowed and breed X parity (for ADG), were found to …

Agribusiness Skills Required By Secondary Vocational Agriculture Students As Perceived By Nebraska Vocational Agriculture Instructors And Agribusiness Managers, David Ray Spotanski

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

The study was conducted to determine what skills are required for a vocational agriculture student to gain employment in a Nebraska agribusiness as perceived by 36 Nebraska vocational agriculture instructors and 180 Nebraska agribusiness managers. A mailed survey was used to collect data for the survey. The survey return rate for the agribusiness respondents was 78 percent and the return rate for the vocational agriculture instructors was 86 percent. The Likert Method of Summated Ratings was used to rate 40 agribusiness skills on a scale of 1 to 9. Means, standard deviations and analysis of variance were computed for each …

Population Dynamics Of The Parasites In Fundulus Zebrinus In The Platte River Of Nebraska, John J. Janovy Jr., Eugene Lee Hardin

John J. Janovy, Jr. Publications

The population dynamics of 7 parasite species or ecotypes were studied in the plains killifish, Fundulus zebrinus, at a single collection site in the South Platte River of Nebraska, U.S.A., for 5 yr. Parasites were: Myxosoma funduli (gill), Trichodina sp. (gill), Gyrodactylus bulbacanthus (gill), Urocleidus fundulus (gill), Gyrodactylus stableri (body surface), and Neascus sp. (= Posthodiplostomum; eyes and body cavity). Parasite densities, prevalences, and variance/mean ratios are reported for 22 samples, totaling 447 fish, over the summer months. Positive correlations were obtained between density and both standardized prevalence and log-transformed variance. Urocleidus fundulus populations were relatively stable with …

Nebraska Bird Review

PELICAN WITH SANDHILLS CRANES. On 17 October 1986, about 1:30 PM, I took a call from Mrs. Darrol Sukraw from Stapleton, who reported a flock of Sandhill Cranes (approximately 100 birds) that contained a single Whooping Crane. After questioning her about the description of the white bird, I felt her observation might be valid and asked her which direction the birds were traveling.

She informed me that the flock had just passed over Stapleton and was flying directly South down highway 83, toward North Platte. This is a distance of about 30 miles. Hoping that I could verify the Whooping …

Individual Heterosis And Breed Effects For Postweaning Performance And Carcass Traits In Four Breeds Of Swine, D. G. Mclaren, D. S. Buchanan, R. K. Johnson

Department of Animal Science: Faculty Publications

Individual heterosis and direct and maternal breed effects for postweaning average daily gain (ADG), off-test age (AGE) and probed backfat thickness (BF) were estimated from data on 1,664 pigs produced in a complete diallel mating system involving the Duroc, Yorkshire, Landrace and Spotted breeds. The same genetic parameters were estimated for various carcass traits by analyses of data collected on 269 barrow carcasses. Significant breed x environment (i.e., year-season farrowed, parity and sex) interactions were found for ADG, AGE and BF. Specific heterosis estimates for ADG and AGE were all highly significant and reasonably consistent among crosses. Overall heterosis for …

A Red-Naped Sapsucker In Sioux County, Nebraska, Mark A. Brogie, Ellen L. Brogie

Nebraska Bird Review

The Red-naped Sapsucker (Sphyrapicus nuchalis) has recently been recognized as a valid species (American Ornithologists' Union, 1985). Its inclusion in the avifauna of Nebraska is based on three birds, all taken in September in the northwestern corner of the state during the years 1919 and 1920 (Bray et al. 1986). Bray et al. (1985) give detailed accounts of these specimens and present an over-view of the species in Nebraska. The following, along with being the first spring record of the species in Nebraska, represents the first verified occurrence of this species in the state since 1920.

Black Rail In Knox County, Nebraska, Mark A. Brogie, Ellen L. Brogie

Nebraska Bird Review

BLACK RAIL IN KNOX COUNTY. NEBRASKA

The Black Rail (Laterallus jamaicensis) is apparently an extremely rare spring and fall migrant in Nebraska (Johnsgard, 1980). No breeding evidence for this species exists for the state. although several field guides show Nebraska at the northern edge of this rail's breeding range. A description of a Black Rail seen 22 April 1980 in Lancaster Co. (NBR 48: 88 is the only accepted record (Class III) of this species in the state (Bray et al., 1986). Whitney et al., 1978) makes no mention of this species for South Dakota. although Iowa …

Insects In Some Nebraska Crops As Food For Pheasant Chicks, R. W. Whitmore, K. P. Pruess, R.E. Gold

Nebraska Bird Review

Insect biomass was estimated for crops grown on an organic, a dryland, and an irrigated farm from 1 June to 15 July, the time period assumed important for Ring-necked Pheasant (Phasianus colchicus) nesting and chick dependence on insect food. Differences due to farming system were not detected. Total insect biomass production during the season was 2,555, 2,173, and 338 mg per square m for oats-sweetclover, oats, and sweetclover, respectively. Leafhoppers were the most abundant insects in oats and oats-sweetclover, with plant bugs the most abundant in sweetclover. Mean standing crop biomass (mg per square m) of only those …

Macgillivray's Warbler In Cedar County, Nebraska, Mark A. Brogie, David A. Stage

Nebraska Bird Review

MacGillivray's Warbler (Oporornis tolmiei) is considered by Johnsgard (1980) to be a rare spring and fall migrant in western Nebraska. with most records from the Panhandle. but reported from as far east as Platte Co. Bray et al (1986) consider it regular and cite a specimen taken in Boone Co.. Whatever the status. this warbler is infrequently encountered in Nebraska. and separating this species from Mourning Warbler (Oporornis philadelphia) can often be difficult. Some authorities believe the two to be conspecific, although Hall (1979) found very few hybrid specimens and Salt (1973) found that they did …

Karyotypic Analysis Of Five Rodents And A Marsupial From Belize, Central America, David W. Burton, John W. Bickham, Hugh H. Genoways, Timothy J. Mccarthy

University of Nebraska State Museum: Mammalogy Papers

Karyotypes and chromosomal banding patterns of six species of small mammals from Belize are presented and discussed in light of relevant data in the literature. Individuals of Heteromys desmarestianus had FN values of 72, which differs from previous reports. G-bands were obtained and compared to fluorescent bands (DAPI) and with the location of NOR sites. The karyotypes of Peromyscus mexicanus, Sigmodon hispidus, Oryzomys couesi, and Ototylomys phyllotis are identical to the karyotypes for these species described in the literature. Active NORs were located on four pairs of chromosomes in O. phyllotis and fluorescent bands obtained with the …

Leafy Spurge Control

Leafy spurge, an aggressive plant, continues to spread in Nebraska greatly reducing the carrying capacity of grazingland. Control on a large area is costly and difficult. Small patches should be treated before they spread and become a more costly problem. The ideal time to treat leafy spurge in much of Nebraska is from mid-May to early June. Leafy spurge is easily spotted at this time as the tops of plants are a …

Effects Of Planting Date On Development Of Net Blotch Epidemics In Winter Barley In Pennsylvania, Leslie M. Delserone, H. Cole Jr.

University of Nebraska-Lincoln Libraries: Faculty Publications

The influence of planting date on fall and spring net blotch epidemics (caused by Pyrenophora teres) was evaluated with the winter barley cultivar Pennrad. Experiments were conducted in Centre County, Pennsylvania, in 1982 and 1983 and in Lancaster County, Pennsylvania, in 1983. The three planting dates evaluated corresponded to the recommended date as well as dates I wk earlier and later than recommended for each specific location. Planting date had a significant influence on fall net blotch epidemics, with the greatest and least disease severities observed in the earliest and latest plantings, respectively. When spring environmental conditions were warm …

Importance Of Attractant Qualities For Improving A New Coyote Delivery System, Steven M. Ebbert, Daniel B. Fagre

Great Plains Wildlife Damage Control Workshop Proceedings

Changes in effectiveness and nontarget species selectivity of a new system for delivering ingestible substances to coyotes (Canis latrans) were examined by systematically varying odor type and quantity used to attract coyotes to the device. The new delivery system's efficacy was comparable to the M-44 in our tests in south Texas. A synthetic lure improved the effectiveness of the delivery system when applied in amounts of 0.10 cc or 0.50 cc. Varying odor type did not increase the incidence of desirable coyote behavior, such as biting, but did increase rates of visitation.

Control Of Ecosystem Processes By Prairie Dogs And Other Grassland Herbivores, James K. Detling, April D. Whicker

Great Plains Wildlife Damage Control Workshop Proceedings

Black-tailed prairie dogs in the mixed-grass prairie at Wind Cave National Park, South Dakota, create habitat patches characterized by altered species composition, lower standing crops of plants, but higher forage quality. Native wildlife species such as bison, pronghorn, and elk preferentially feed on these prairie dog colonies and likely derive nutritional benefits from doing so.

The Lure Crop Alternative, Steven D. Fairaizl, William K. Pfeifer

Great Plains Wildlife Damage Control Workshop Proceedings

Lure crops are proposed as an alternative to scaring waterfowl. The lure crop works on the principle of permitting waterfowl to feed undisturbed for the duration of the damage season in an unharvested field of their choice thereby utilizing trampled grain. Waterfowl from adjacent areas are encouraged to use the lure crop through the use of scaring devices placed in protected fields. General criteria for implementation of a lure crop project and specific criteria for lure crop purchases are presented. Factors contributing to a successful lure crop and problems which reduced lure crop effectiveness are identified. Benefit/cost analysis of lure …

Aerial Hunting Takes Sheep-Killing Coyotes In Western Montana, Guy Connolly, Bart W. O'Gara

Great Plains Wildlife Damage Control Workshop Proceedings

This paper reports limited data to document that depredating coyotes were shot from a helicopter in western Montana in 1976. Coyotes marked themselves by puncturing diphacinone-filled collars on the necks of sheep they attacked. Subsequently, 11 coyotes were shot from a helicopter on 3 ranches where collared sheep had been attacked. Six coyotes contained diphacinone and thus were confirmed as having recently attacked or fed on collared sheep.
