Behaviour of pre-parturient sows housed in intensive outdoor or indoor systems. Repositório Alice
HÖTZEL, M.J.; MACHADO FILHO, L.C.P.; COSTA, O.A.D..
This work compared the behaviour of pre-parturient sows housed in intensive confined and outdoor systems, during the morning and afternoon prior to delivery. Eight sows were kept individually in farrowing crates or in paddocks with access to fresh pasture from 8 to 10 days before expected parturition. All outdoor sows built a nest within 24 hours before farrowing. On the morning and afternoon before farrowing they spent 6.5% of the time collecting grass and 7.5% of the time organizing the nest. Outdoor sows were observed more often than confined sows rooting (4.60% vs. 0.25%), feeding (10.2% vs. 3.0%), standing (51% vs. 13%) and walking (8% vs. 0%). Indoor sows redirected the nesting behaviour to other behaviours like attempts to dig the ground, nosing,...

DAIRY '96, PART I: REFERENCE OF 1996 DAIRY MANAGEMENT PRACTICES AgEcon
Ott, Stephen L..
The NAHMS Dairy '96 Study was designed to provide both participants and the industry with information on the nation's dairy animal population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid sample yielding 2,542 producers. Included in the study were 20 states that represented 83.1 percent of the U.S. milk cows as of January 1, 1996. NASS interviewers collected data for Part I via a questionnaire administered on-farm from January 1 through 26, 1996. Contact for this paper: Steven Ott

DAIRY '96, PART II: CHANGES IN THE U.S. DAIRY INDUSTRY: 1991-1996 AgEcon
Ott, Stephen L..
The NAHMS Dairy '96 Study was designed to provide both participants and the industry with information on the nation's dairy animal population for education and research. This report contains demographic changes of the U.S. and world dairy industry from a historical perspective from data provided by the National Agricultural Statistics Service (NASS), Census of Agriculture, and Foreign Agriculture Service. Results of two NAHMS national studies overview changes in the U.S. dairy industry in the 5-year period of 1991 to 1996. The 1991 National Dairy Heifer Evaluation Project included herds of 30 or more milk cows and heifer-rearing operations in 28 states representing 83 percent of U.S. milk cows. NAHMS Dairy '96 described dairy production for operations...

DEVELOPMENT AT THE URBAN FRINGE AND BEYOND: IMPACTS ON AGRICULTURE AND RURAL LAND AgEcon
Heimlich, Ralph E.; Anderson, William D..
Land development in the United States is following two routes: expansion of urban areas and large-lot development (greater than 1 acre per house) in rural areas. Urban expansion claimed more than 1 million acres per year between 1960 and 1990, yet is not seen as a threat to most farming, although it may reduce production of some high-value or specialty crops. The consequences of continued large–lot development may be less sanguine, since it consumes much more land per unit of housing than the typical suburb. Controlling growth and planning for it are the domains of State and local governments. The Federal Government may be able to help them in such areas as building capacity to plan and control growth, providing financial incentives for channeling growth...

Housing, pasture management and roughage supplementation: on the pre-weaning growth of goats in the tropical Northeast of Brazil. Repositório Alice
OLIVEIRA, E. R. de; LIMA, F. de A. M.; PANT, K. P..
Abstract: This experiment was undertaken with 100 adult does of an undefined but most com- mon type of goats called "sem laça definida" (SRD). The does were divided into four equal groups (each of 25 does) of comparable age and weights. These were allotted to four treatments as follows: native "caatinga" pastures with either (1) ground fIoor or (2) raised slatted fIoor system of housing; cleared pastures with raised fIoor system of housing either (3) without or (4) with ad libitum supple- mentation of green elephant grass (Pennisetum prtrpureum Schum.) only during dry months. Data on 250 kids born to these do es over a period of two years and maintained under the saIne treatment as their mothers were analysed for their pre-weaning growth were studied....

Is agricultural zoning exclusionary? AgEcon
Gottlieb, Paul D.; Rudel, Thomas; O'Neill, Karen; McDermott, Melanie.
In rapidly suburbanizing areas, minimum lot sizes of ten acres or greater are often used to discourage residential development and to maintain agricultural critical mass. Because of significant development pressure in these places, there is a good chance these lot size regulations will bind. Such “down-zoning” often appears alongside the purchase of agricultural and conservation easements that reduce housing development even more. Whatever the benefits of such policies for agriculture and the environment, they raise obvious concerns about housing supply and affordability. The issue of affordability should be analyzed at the regional scale, since we would normally expect some high-income, low density enclaves to exist within any metropolitan area....

MARGINAL PRICE OF LAKE RECREATION AND AESTHETICS: AN HEDONIC APPROACH AgEcon
Lansford, Notie H., Jr.; Jones, Lonnie L..
Efficient allocation of water requires knowledge of water's value in both consumptive and nonconsumptive uses. This study estimates the marginal value of water in lake recreational and aesthetic (RA) use. An hedonic price equation (employing the Box-Cox functional form) indicates lake front location, distance to lake, and scenic view are significant RA characteristics of housing. Water front properties command a premium price for the private access they offer. Beyond the water front, the marginal RA price falls rapidly with increasing distance, becoming asymptotic to some minimum. Twenty-two percent of housing price is found to be attributable to the RA component.

Meta Analysis in Model Implementation: Choice Sets and the Valuation of Air Quality Improvements AgEcon
Banzhaf, H. Spencer; Smith, V. Kerry.
We document the sensitivity of welfare estimates derived from discrete choice models to assumptions about the choice set. Such assumptions can affect welfare estimates through both the estimated parameters of the model and, conditional on the parameters, the substitution among alternatives. Our analysis involves estimates of the benefits of air quality improvements in Los Angeles based on discrete choices of neighborhood and housing. We further illustrate the use of meta analysis to document and summarize voluminous information derived from repeated sensitivity analyses.

Profile of Hired Farmworkers, A 2008 Update AgEcon
Kandel, William.
Hired farmworkers make up a third of the total agricultural labor force and are critical to U.S. agricultural production, particularly in labor-intensive sectors such as fruits and vegetables. The hired farmworker labor market is unique because it includes a large population of relatively disadvantaged and often unauthorized workers, a portion of whom migrate to, and within, the United States. Recent economic and demographic trends, such as changing agricultural production methods that permit year-round employment, expanding immigrant populations in nonmetropolitan counties, and growing concerns over U.S. immigration policies, have elicited increased interest in hired farmworkers. This 2008 profile serves as an update to the 2000 Economic Research Service...

The impact of large-lot zoning and open space acquisition on home building in rural communities AgEcon
Gottlieb, Paul D.; O'Donnell, Anthony; Rudel, Thomas; O'Neill, Karen; McDermott, Melanie.
Local governments in the United States use a wide range of tools to preserve rural landscapes. Some of these tools, like the purchase or transfer of development rights, are generally welcomed by farmers and other large landowners. Other tools, like increasing the minimum lot size in a town’s agricultural zone, are more controversial because they are believed to have negative effects on landowner wealth. In this contentious policy environment, it would be useful to know which land use tools actually work to control residential growth, thus achieving the consensual objective of rural preservation. It is reasonable to suppose that large-lot zoning and open space preservation will both reduce the number of homes in a community when it is fully developed....
