Factors Influencing Fetal Growth And Birth Weight In Cattle, Calvin L. Ferrell

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Fetal growth, as indicated by birth weight, has important influences on animal production. Birth weights lower than optimum are associated with reduced energy reserves, lowered thermoregulatory capability, and increased calf deaths at or near birth. In addition, low birth weights are related to low rates of growth after birth and decreased mature size. Conversely, birth weights greater than optimum are associated with greater calving difficulty. Primarily because of the increased calving difficulty, calf losses at birth and difficulties if rebreeding the cow are increased.

Fetal growth, hence birth weight, is influenced by numerous factors including number of fetuses, sex, parity …

Seasonal And Annual Variation In Weight And Biochemical Content Of The Zebra Mussel, Dreissena Polymorpha, In Lake St. Clair, Thomas F. Nalepa, Joann F. Cavaletto, Mark Ford, Wendy M. Gordon, Marijo Wimmer

United States Department of Commerce: Staff Publications

Zebra mussels, Dreissena polymorpha, were collected monthly from April/May to November in 1990 and 1991 from two sites in Lake St. Clair. The sites were characterized by relatively high and low mussel densities. The following variables were measured: ash-free dry weight (AFDW) per unit shell length (SL), lipid content and classes, carbon content, and nitrogen content. Mussels from the high-density site had a lower AFDW:SL relationship, lower lipid content, and a lower C:N ratio than mussels from the low-density site. Seasonal trends in these variables were consistent between sites and years. AFDW:SL, lipid, and carbon content were highest in …

Chapter 1 The Enigma Of Drought, Donald A. Wilhite

National Drought Mitigation Center: Faculty Publications

Drought is the most complex and least understood of all natural hazards, affecting more people than any other hazard (Hagman, 1984). For the past several decades, we have been reminded again and again of the ravages of drought and the inability of most societies to effectively mitigate impacts in the short term and reduce vulnerability in the longer term. In fact, most scientists would agree that vulnerability to drought is increasing for a number of reasons, the most important of which may be the increasing pressure of an expanding population base on limited water and other natural resources.

13.4.8. Options For Water-Level Control In Developed Wetlands, J. R. Kelley Jr., M. K. Laubhan, F. A. Reid, J. S. Wortham, L. H. Fredrickson

Waterfowl Management Handbook

Wetland habitats in the United States currently are lost at a rate of 260,000 acres /year (105,218 ha/year). Consequently, water birds concentrate in fewer and smaller areas. Such concentrations may deplete food supplies and influence behavior, physiology, and survival. Continued losses increase the importance of sound management of the remaining wetlands because water birds depend on them.

Human activities modified the natural hydrology of most remaining wetlands in the conterminous United States, and such hydrologic alterations frequently reduce wetland productivity. The restoration of original wetland functions and productivity often requires the development of water distribution and discharge systems to emulate …

13.2.11. Increasing Waterfowl Nesting Success On Islands And Peninsulas, John T. Lokemoen

Waterfowl Management Handbook

Waterfowl that nest in uplands in the prairie pothole region have had low recruitment rates in recent decades, primarily because of predation. The loss of breeding waterfowl and their progeny has generated interest in management techniques that safeguard incubating hens and their eggs. Developing islands and peninsulas for nesting waterfowl has potential because these sites are naturally attractive to breeding ducks and geese. In fact, dense nesting colonies of ducks developed on some islands when successful females and a portion of their female progeny returned in subsequent years.

Managers have successfully duplicated the beneficial attributes of islands by developing various …

13.4.13. Management And Control Of Cattails, Richard S. Sojda, Kent L. Solberg

Waterfowl Management Handbook

The response of wetland vegetation to management can only be interpreted by considering an intricate mix of physiological, ecological, and temporal factors. Because cattail management is important for many freshwater marshes, the purpose of this leaflet is to present autecological principles for such management.

A 50:50 ratio of open water and vegetation is a frequent objective when managing cattail marshes in North America. When a particular marsh has been extensively flooded for some time and few cattails remain, managers may wish to foster more cattails to develop such hemi-marsh conditions. The reverse is followed when a marsh is dominated by …

Review Of The Origins Of Agriculture And Settled Life By Richard S. Macneish. Norman And London: University Of Oklahoma Press, 1992. 433 Pages., Alan J. Osborn

Department of Anthropology: Faculty Publications

Excerpt:

Following a brief review of the "environmentalist's" (e. g., Ratzel, de Candolle, Childe, Braidwood, and Flannery) and the "materialist's" (e. g., Marx, Vavilov, D. Harris, Binford, and Cohen) accounts, MacNeish presents his "trilinear theory." It consists of "three hypothetical models and three hypotheticaI sets of causes" for the development of plant domestication and sedentism. This "trilinear theory" is a world culture history similar to the multilinear developmental frameworks proposed "by Julian Steward (The Theory of Culture Chtange: The Methodology of Multilinear Evolution, 1955). MacNeish's multilinear scheme is cross-cut by three developmental stages, i. e., food collectors, transitional …

G93-1172 Starting Cattle, Dicky D. Griffin, Louis Perino, Don Hudson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide gives guidelines to help feedlot operators prepare and establish a plan for starting new cattle on feed that minimizes stress, reduces morbidity (sickness) and improves performance.

An animal's first few weeks in a feedlot can influence performance throughout the entire feeding period. The cattle are adapting to a new environment and may be exposed to disease, some for the first time. It is vitally important to prevent and deal with health problems at this time to prevent loss of performance.

Cattle entering the feedlot encounter a range of problems that arise from several sources, including health and nutritional …

G93-1169 Coalitions For Building Community Understanding (Revised April 1994), Georgia L. Stevens

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide identifies eight steps for coalitions involved in building community understanding and applies them to the issue of school-age child care.

The process of building community understanding is an important one, regardless of the area of concern. As more and more citizens recognize a particular problem, that problem moves from the private to the public domain and requires the involvement of a larger segment of the community. Though this NebGuide deals specifically with the example of school-age child care, the process of involving the whole community is relevant to any area of policy-making.

13.2.2. The North American Waterfowl Management Plan: A New Approach To Wetland Conservation, Angela V. Graziano, Diana H. Cross

Waterfowl Management Handbook

The decline of waterfowl populations and the loss of wetlands are high-ranking environmental concerns in North America. The importance of these issues is reflected in an ambitious wetland recovery plan, the North American Waterfowl Management Plan. Signed in 1986 by the U.S. and Canadian federal governments, the plan features specific strategies to reverse the declines in waterfowl numbers and wetland acreage. The goal is to restore waterfowl populations to a level common to the 1970’s by improving and securing long-term protection of 6 million acres (2.4 million ha) of habitat in 34 areas of major concern.

The key to achieving …

13.3.14. Detrital Accumulation And Processing In Wetlands, Patrick A. Magee

Waterfowl Management Handbook

Wetlands are among the most productive ecosystems on earth (Fig. 1) and are often characterized by lush growths of hydrophytes. However, direct consumption of wetland plants by animals is relatively low, and, therefore, much of the biomass and energy assimilated by hydrophytes becomes detritus or senesced plant litter. Nutrients released by detritus into the water and soil are assimilated by microorganisms, algae, plants, and small aquatic animals. Through this process, energy is transferred from detritus to other biotic components of a wetland. Plant litter ultimately decomposes.

Litter processing is regulated by environmental factors, microbial activity, the presence and abundance of …

13.1.15. Life History And Habitat Needs Of The Black Brant, Dirk V. Derksen, David H. Ward

Waterfowl Management Handbook

The black brant is a sea goose that depends on coastal habitats from high arctic nesting sites in Canada, Alaska, and Russia to wintering areas in the Pacific coastal states, the Baja California peninsula, and mainland Mexico estuaries. Population estimates are based on aerial surveys in Mexico, California, Oregon, and Washington during mid-winter. Despite much annual variability in estimates, a plot of the counts from 1964 to 1992 reveals a significant downward trend in the winter populations (Fig. 1). Three of four major colonies on the Yukon&#;Kuskokwim (Y&#;K) delta declined an average of 60% during the first half of the …

G93-1138 Water Quality And Requirements For Dairy Cattle, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide stresses the importance to the dairy cow of water, an essential but often overlooked nutrient.

Providing insufficient water or water of poor quality to dairy cattle can limit milk production and growth, and can cause health problems. An adequate supply of clean water promotes normal rumen function, high feed intake, digestion and nutrient absorption. Water also maintains blood volume, supplies tissue needs, and makes up about 87 percent of the milk secreted by the cow. The following sections discuss water intake and requirements, water quality and guidelines for proper use of cattle waterers.
