| Well being of animals had been historically a public concern, since the beginning of human kind history. As world's population grows there is a need for food including meat. In the last decades there has been a great improvement in poultry production based on the careful control of several aspects, among which nutrition and management (environment, health and rearing systems). Nowadays, the search for good welfare conditions is a global tendency in animal production; however issues surrounding farm animal welfare or well-being, such as definitions, measurements, interpretation, and perception, continue to be controversial. It is known that the result of a broiler not adequately housed is a direct loss in production which leads towards a thought that... |

| 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... |

| 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. |

| ABSTRACT A study was conducted to investigate the influence of selenium nanoparticles (SeNPS) and inorganic selenium supplementation in the drinking water on behavior, performance, and immunity of Arbor Acres® and Ross®308 broilers exposed to E. coli O157:H7 1.6 × 108 challenge at the 10th day of age. 180 one-day-old female broilers were divided into six groups, each with 30 chicks. G1 and G4 were supplied with 1 mL SeNPS 100 mg.L-1/L, G2 and G5 were supplied with 1 mL inorganic selenium 100 mg.L-1/L, and G3 and G6 were supplied with non-supplemented water. Where, G1, G2, and G3 were Arbor Acres®, while G4, G5, and G6 were Ross®308 broilers. A total of 1280 samples (160 sera, 160 intestinal swabs and 960 organ samples including liver, spleen, bursa, heart,... |

| In the Brazilian meat production scenario broiler production is the most dynamic segment. Despite of the knowledge generated in the poultry production chain, there are still important gaps on Brazilian rearing conditions as housing is different from other countries. This research study aimed at analyzing the variation in bird skin surface as function of heat distribution inside broiler houses. A broiler house was virtually divided into nine sectors and measurements were made during the first four weeks of the grow-out in a commercial broiler farm in the region of Rio Claro, São Paulo, Brazil. Rearing ambient temperature and relative humidity, as well as light intensity and air velocity, were recorded in the geometric center of each virtual sector to... |

| 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.... |
