Management Of Prairie Dog Populations In Wind Cave National Park, Richard W. Klukas

Great Plains Wildlife Damage Control Workshop Proceedings

Since the late 1920's there have been periodic control programs on black-tailed prairie dogs in Wind Cave National Park. The most recent control effort, which began in 1982, resulted in the reduction of total dogtown acreage from 2,000 to 750 acres. Recent studies carried out within the park have provided managers with more soundly based justification for carrying out control programs. The same information also points to the importance of maintaining prairie dog populations at or above certain minimum levels and the need for integrating this control program with several of the other resource management programs being carried out in …

Maternal And Nutritional Contributions To Infant Rats’Activational Responses To Ingestion, Brian H. Bornstein, Leslie M. Terry, Joseph A. Browde Jr.

Department of Psychology: Faculty Publications

Infant rats deprived of food, maternal care, and the opportunity to suckle display a dramatic behavioral activation and vigorously ingest when provided milk through oral cannulas. These experiments assessed which components of deprivation are important in producing these responses to milk. Nutritional deprivation alone, with or without the presence of an active maternal female, appears to be sufficient to produce ingestion. Behavioral activation, on the other hand, appears to require both nutritional deprivation and deprivation from a maternal female. The effect of maternal stimulation on later behavioral reactivity was not a function of the pups’ opportunity to suckle. However, active …

Genetic Parameters For First Lactation Milk Yields At Three Levels Of Herd Production, J. C. De Veer, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

A multivariate linear model was used to estimate sire variance and covariance components and residual variance components for first lactation milk yield and logarithms of yield at three herd production levels using Restricted Maximum Likelihood with the Expectation- Maximization algorithm. Data for four separate analyses were 305-d, mature equivalent first lactation milk records from cows sired artificially in the northeastern United States that freshened in 1970, 1971, 1976, and 1984. Respective numbers of records for each year were 42,618, 40,207, 33,581, and 34,196. Corresponding numbers of sires were 298, 289, 305, and 313. Herd production level was defined by mean …

Aspects Of Selection For Performance In Several Environments With Heterogeneous Variances, D. J. Garrick, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Dairy cattle evaluation schemes routinely assume homogeneous variance with respect to environment. Increasing evidence suggests the presence of systematic changes in variance components associated with mean level of performance. Best linear unbiased prediction procedures that account for heterogeneity are reviewed. The consequences of incorrectly assuming homogeneity for evaluation are demonstrated for a progeny test and an artificial breeding program that screens dams of sires from heterogeneous populations. Selection assuming homogeneity can be very efficient when heritability, and therefore accuracy of selection, is greatest in the more variable environment. Conversely, appreciable reduction in response results when heritability is greater in the …

Chapter 25 The Role Of Government In Planning For Drought: Where Do We Go From Here?, Donald A. Wilhite

National Drought Mitigation Center: Faculty Publications

During the twentieth century, governments have typically responded to drought by providing emergency, short-term, and long-term assistance to distressed areas. Emergency and short-term assistance programs are often reactive, a kind of "band-aid" approach to more serious land and water management problems (Rosenberg, 1980; Hamer, 1985; Wilhite, et al., 1986). Actions of this type have long been criticized as inefficient and ineffective by the scientific community and government officials, as well as by recipients of relief. Long-term assistance programs are far fewer in number, but they are proactive. They attempt to lessen a region's vulnerability to drought through improved management and …

Farm Consolidation In The Northern And Central States Of The Great Plains, Bradley H. Baltensperger

Great Plains Quarterly (through 2013)

During the past half century, American agriculture has been revolutionized and rural America has been dramatically transformed. The industrial revolution had arrived in American agriculture in the 1840s when machines and animal power began replacing some hand tools wielded by humans. But not until the 1930s, when petroleum-driven machines rapidly displaced both animal and human power, did this revolution intensify sufficiently to have significant impacts on rural life and farm numbers. Since that time, reliance on farm-produced inputs-fertilizer, seed, energy-has given way to dependence on purchased factors of production. The commercial aspects of farming have nearly obliterated the subsistence components. …

Scientific Research Programmes: Toward A Synthesis And Evaluation Of Crm Archaeology, Alan J. Osborn

Department of Anthropology: Faculty Publications

Archaeologists involved in conservation archaeology and/or cultural resource management have frequently been confronted with the dilemma described by Fowler (1982). Cultural resource management projects most generally have to be conducted within a restricted geographical area within a specified period of time. Many archaeologists have chosen to deal with the resource management dilemma in one of three ways. First, there are those that have chosen to view cultural resource management primarily as a professional service. Practitioners of "service" archaeology conduct archaeological surveys and excavations in order to determine the frequency, location, and extent of cultural remains within a specified area. Investigations …

Relationships Between Rate Of Growth, Catheptic Enzymes And Meat Palatability In Young Bulls, Chris R. Calkins, S. C. Seideman, J. D. Crouse

Department of Animal Science: Faculty Publications

Relationships between rate of growth, endogenous muscle enzymes and meat palatability were investigated in 48 young (13 mo) Angus bulls. After backgrounding for 4 mo, bulls were placed on a high-energy diet for 30 d, at which time they were assigned randomly to one of three feeding treatments: 1) high energy (ad libitum-fed), 2) maintenance energy (restriction-fed to maintain body weight) or 3) sub-maintenance energy (restriction-fed to lose .68 kg/d). Cattle were slaughtered after 30 or 60 d on trial. Cathepsins B and H and β-glucuronidase in the longissimus muscle were quantitated at slaughter. Serum hydroxyproline, longissimus muscle collagen, taste-panel …

G87-849 Vaccinations In Sheep Flocks, Dale M. Grotelueschen

University of Nebraska-Lincoln Extension: Historical Materials

High economic return per dollar invested can result from proper flock health management. Vaccinations are part of health management.

A preventive health program in modern sheep production systems is advisable. High economic return per dollar invested can result from proper flock health management. Health management is much more than a vaccination program. Vaccinations themselves are considered for a variety of reasons. These include disease risk management and strict prevention. Vaccinations may also be indicated in situations where management practices other than vaccine administration do not produce optimum health or economic benefits.

It is not feasible to outline one vaccination program …

G87-851 Improving Reproductive Performance And Productivity Of Beef Herds, Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

NebGuide discusses management practices that can be used to improve reproduction and productivity of beef herds. The major objective of cow-calf producers should be to wean a calf from each cow every year. The average calf crop weaned in Nebraska is estimated at 80 calves weaned per 100 cows in breeding herds. A realistic goal is 90 to 95 calves weaned per 100 cows.

Effect Of Level Of Protein And Supplemental Choline On Reproductive Performance Of Gilts Fed Sorghum Diets, C. V. Maxwell, R. K. Johnson, W. G. Luce

Department of Animal Science: Faculty Publications

A total of 214 gilts was used (two trials) to determine the effect of protein level and choline supplementation during gestation on weight gain, conception rate and subsequent reproductive performance. The gilts were fed either a 12 or 16% crude protein sorghum-soybean meal diet containing either a high supplemental choline level or no supplemental choline in a 2 • 2 factorial arrangement of treatments Conception rate was not influenced by either protein or choline level. Choline supplementation increased pig weight at 42 d of age (P<.14) and litter weight at 21 (P<.12) and 42 d (P<.1). Gilts fed the 16% protein diet produced larger pigs at 42 d (P<.13) and heavier litters at birth, (P<.l) 21 d (P<.14) and 42 d (P<.05) than gilts fed the 12% protein diet. A larger choline effect on litter size and pig and litter weight was observed for gilts fed the 12% protein diet than for those fed the 16% gestation diet, although the protein-choline interaction was not significant for any traits measured. The incidence of spraddle leg condition was low and was not affected by level of dietary protein or supplemental choline.
