Evaluation Of Procedures To Predict Fat-Free Lean In Swine Carcasses, Rodger K. Johnson, E. P. Johnson, R. Goodwin, J. W. Mabry, R. K. Miller, O. W. Robison, H. Sellers, M. D. Tokach

Department of Animal Science: Faculty Publications

The objectives were to develop equations for predicting fat-free lean in swine carcasses and to estimate the prediction bias that was due to genetic group, sex, and dietary lysine level. Barrows and gilts (n = 1,024) from four projects conducted by the National Pork Board were evaluated by six procedures, and their carcass fat-free lean was determined. Pigs of 16 genetic groups were fed within weight groups one of four dietary regimens that differed by 0.45% in lysine content and slaughtered at weights between 89 and 163 kg. Variables in equations included carcass weight and measures of backfat depth and …

Effects Of Food Quality On Growth And Carcass Composition In Lambs Of Two Breeds And Their Cross, R. M. Lewis, J. M. Macfarlane, G. Simm, G. C. Emmans

Department of Animal Science: Faculty Publications

The effects offood quality, breed type and sex (ram and ewe) on Iamb growth and carcass composition, and their changes throughout growth, were measured. The three breed typeswereScottish Blackface (B; no. = 24), Suffolk (S; no. = 28) and their reciprocal crosses (X; no. 33). The lambs had free access to a nutritionally non-limiting food, H, or a bulky food, L. Each lamb was scanned using X-ray computed tomography to measure the weights offat, lean and bone in the carcass at three degrees of maturity (0·30, 0·45 and 0·65) in live weight. Live weight and food intake data were recorded …

Exogenous Estrogen Boosts Circulating Estradiol Concentrations And Calcium Uptake By Duodenal Tissue In Heat-Stressed Hens, K.K. Hansen, M.M. Beck, S.E. Scheideler, Erin E. Blankenship

Department of Animal Science: Faculty Publications

In the hen, heat stress (HS) disrupts shell calcification and reproductive processes, including hormone synthesis and egg production. Two studies were conducted to investigate palliative effects of exogenous estrogen or dietary vitamin D3 on Ca homeostasis and reproductive physiology during HS. Study 1: Hy-Line W36 hens were randomly assigned to thermoneutral (TN) or HS treatments and to 1 of 7 estrogen treatments: zero (control) or one Compudose 200 implant given 1, 2, 3, 8, 9, or 10 d before onset of HS. With no implant, HS reduced plasma estradiol (E2) and total Ca absorbed (CaT) by duodenal cells (P < 0.05). In TN hens with implants, plasma E2 tripled within 24 h (P < 0.05) and remained elevated (P < 0.05) through d 9. In HS hens with implants, plasma E2 rose 6-fold (P < 0.05) to equal TN+E2 concentrations and remained elevated through d 10. In TN and HS hens with implants, the rate of Ca absorption (CaTR) and CaT increased dramatically; the responses were quadratic and essentially identical. Study 2: Hy-Line W36 hens were provided diets formulated either according to NRC requirements (NRC, 1994), or with the addition of 22,000 IU/kg vitamin D3 (+VD hens). A 24-h HS episode was imposed 2 wk after initiation of the dietary regimen. Duodenal samples were collected for Ca absorption assays after the 24-h HS episode. Both CaTR and CaT in +VD hens were approximately 3-fold higher than in hens in the NVD group (P = 0.102). The results lead to the conclusion that exogenous estrogen, high levels of dietary vitamin D, or both, before a HS episode, are efficacious in alleviating at least some of the effects of HS and should be further investigated.

Linking Wild And Captive Populations To Maximize Species Persistence: Optimal Translocation Strategies, Brigitte Tenhumberg, Andrew J. Tyre, Katriona Shea, Hugh P. Possingham

School of Biological Sciences: Faculty Publications

Captive breeding of animals is widely used to manage endangered species, frequently with the ambition of future reintroduction into the wild. Because this conservation measure is very expensive, we need to optimize decisions, such as when to capture wild animals or release captive-bred individuals into the wild. It is unlikely that one particular strategy will always work best; instead, we expect the best decision to depend on the number of individuals in the wild and in captivity. We constructed a first-order Markov-chain population model for two populations, one captive and one wild, and we used stochastic dynamic programming to identify …

Women’S Work, Child Care, And Helpers-At-The-Nest In A Hunter-Gatherer Society, Raymond Hames, Patricia Draper

Department of Anthropology: Faculty Publications

Considerable research on helpers-at-the-nest demonstrates the positive effects of firstborn daughters on a mother’s reproductive success and the survival of her children compared with women who have firstborn sons. This research is largely restricted to agricultural settings. In the present study we ask: “Does ‘daughter first’ improve mothers’ reproductive success in a hunting and gathering context?” Through an analysis of 84 postreproductive women in this population we find that the sex of the first- or second-born child has no effect on a mother’s fertility or the survival of her offspring. We conclude that specific environmental and economic factors underlay the …

Comparisons Of Angus, Charolais, Galloway, Hereford, Longhorn, Nellore, Piedmontese, Salers, And Shorthorn Breeds For Weight, Weight Adjusted For Condition Score, Height, And Condition Score Of Cows, Jesus Arango, L. V. Cundiff, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Breed differences for weight (CW), height (CH), and condition score (CS) were estimated from records (n &#;&#;12,188) of 2- to 6-yr-old cows (n &#; 744) from Cycle IV of the U.S. Meat Animal Research Center’s Germplasm Evaluation (GPE) Program. Cows were produced from mating Angus and Hereford dams to Angus, Hereford, Charolais, Shorthorn, Galloway, Longhorn, Nellore, Piedmontese, and Salers sires. Samples of Angus and Hereford sires were 1) reference sires born from 1962 through 1970 and 2) 1980s sires born in 1980 through 1987. The mixed model included cow age, season of measurement and their interactions, year of birth, pregnancy-lactation …

Covariance Functions And Random Regression Models For Cow Weight In Beef Cattle, Jesus Arango, L. V. Cundiff, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Data from the first four cycles of the Germplasm Evaluation program at the U.S. Meat Animal Research Center were used to evaluate weights of Angus, Hereford, and F1 cows produced by crosses of 22 sire and 2 dam (Angus and Hereford) breeds. Four weights per year were available for cows from 2 through 8 yr of age (AY) with age in months (AM). Weights (n &#;&#;61,798) were analyzed with REML using covariance function-random regression models (CF-RRM), with regression on orthogonal (Legendre) polynomials of AM. Models included fixed regression on AM and effects of cow line, age in years, season of …

Expelling From Top And Bottom: The Changing Role Of Scatology In Images Of Peasant Festivals From Albrecht Dürer To Pieter Bruegel, Alison Stewart

School of Art, Art History, and Design: Faculty Publications and Creative Activity

During the first half of the sixteenth century, the earliest visual representations of peasant festivals in European art were produced in Germany. These works, all prints, showcase peasants expelling their drink with the result that art historians today, nearly 400 years later, have described these prints as gross and indecent. In their revulsion and distancing from sixteenth-century Germany’s insistently colorful visual and verbal vocabulary, art historians of Northern European art appear to have stressed both the values and preferences of their own twentieth-century culture and that of the sixteenth-century Netherlands rather than those of the society that produced them—sixteenth-century Germany. …

Biotin Deficiency Decreases Life Span And Fertility But Increases Stress Resistance In Drosophila Melanogaster, Anette Landenberger, Hadise Kabil, Lawrence G. Harshman, Janos Zempleni

Lawrence G. Harshman Publications

Biotin deficiency is associated with fetal malformations and activation of cell survival pathways in mammals. In this study we determined whether biotin status affects life span, stress resistance, and fertility in the fruit fly Drosophila melanogaster. Male and female flies of the Canton-S strain had free access to diets containing 6.0 (control), 4.8, 2.5, or 0 pmol biotin/100 mg. Biotin concentrations in diets correlated with activities of biotin-dependent propionyl-CoA carboxylase and biotin concentrations in fly homogenates, but not with biotinylation of histones (DNA-binding proteins). Propionyl-CoA carboxylase activities and biotin concentrations were lower in males than in females fed diets …

Property Valuation May Be Reduced By Proximity To Livestock Operation, J. David Aiken

Nebraska Swine Reports

Livestock odors must be taken into account when counties determine the fair market value of rural residences for property tax purposes. Livestock odors may reduce property values and property valuation. Such reductions may lead to legal nuisance liability claims against livestock producers who are not protected by the Nebraska Right to Farm Act, and may also become a factor in livestock facility zoning decisions.

Coping With Hard Times In Nw Iceland: Zooarchaeology, History, And Landscape Archaeology At Finnbogastaðir In The 18th Century, Ragnar Edvarsson, Sophia Perdikaris, Thomas H. Mcgovern, Noah Zagor

School of Global Integrative Studies: Faculty Publications

During a cooperative archaeological project in NW Iceland (Strandasýsla) involving the Icelandic National Museum and Hunter College of the City University of New York.1990 season, a small rescue excavation at the site of Finnbogastaðir generated a quantifiable collection of animal bones dating to the early modern period, mainly to the 18th century. The 18th c was a period of hardship in much of Iceland, with widespread tenantry, adverse climate, and degradation of many terrestrial landscapes posing severe challenges to poor farmers- perhaps most intensely in the Vestfirðir. The animal bone collection from Finnbogastaðir reflects a multi-stranded subsistence economy involving seals, …

Rabies In Nebraska, David R. Smith, Annette K. Bredthauer

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska is currently experiencing an outbreak of rabies in animals after many years with few cases. The last rabies outbreak in the state peaked in 1981 with nearly 200 animal cases diagnosed that year. After many years with few cases, many people have become complacent about this deadly disease. This NebFact describes rabies in animals and explains how people can protect themselves, as well as their pets or livestock from rabies exposure.
