Provedor de dados: 70
Autores: Lima,Karla A. O.; Nääs,Irenilza de A.; Garcia,Rodrigo G.; Borille,Rodrigo; Caldara,Fabiana R.
Broiler production is highly dependent on the use of artificial light. The light source may affect the effectiveness of housing conditions due to increasing ambient temperature and concentration of noxious gases. This research aimed to evaluate the effects of different bulb types on the thermal, aerial, and acoustic environment of broiler aviaries. The experiment was carried out at a commercial broiler farm in Dourados, Mato Grosso do Sul State, Brazil. Three aviaries were used, and two flocks of male broilers from Cobb® genetic strain were reared from the first day to slaughter. Each aviary was equipped with a different light source, comprising the adopted treatments (A1 - incandescent light bulb, control; A2 - sodium vapor light bulb; A3 - fluorescent...

ISSUES OF DEMAND SPECIFICATION AND INDUSTRY STRUCTURE IN TURKEYS AND BROILER CHICKENS
Provedor de dados: 31
Autores: Cheney,   Laura Martin; Brown,   A. Blake; Yamano,   Takashi; Masterovsky,   Michael.
Factors unique to the turkey industry suggest that conclusions concerning market structure and demand specification drawn from aggregate poultry data cannot necessarily be extrapolated to the turkey industry.  The Wu-Hausman endogeneity test is used to examine demand specifications and industry structure specifically for turkey meat.  In contrast to general poultry, quantity-not price-is found to be predetermined in demand models that use annual turkey data.  Quarterly demand analysis suggests this result stems from biological cycles that limit a producer's ability to react to price change and the use of a weighted average for determining price and quantity.

Provedor de dados: 31
Autores: Harrison,   R. Wes; Sambidi,   Pramod R.
A national survey of broiler industry executives is conducted to analyze site-specific factors related to the broiler-complex location problem.  Conjoint analysis is used to analyze the broiler complex location decision.  Feed costs, community attitude toward the broiler industry, availability of geographically concentrated growers, unemployment rates, and wage rates were found to be the top five factors affecting broiler company location decisions.  The quality of roads between feed mill and growers; electricity, heating, water, and sewage costs; and the number of potential growers in the region were also found to be important.

Drinking water as a risk factor to poultry health
Provedor de dados: 89
Autores: Amaral,LA do.
In the poultry industry, the use of water with adequate physical, chemical and microbiological quality it is of fundamental importance. Since many birds have access to the same water source, quality problems will affect a great number of animals. The drinking water plays an important role in the transmission of some bacterial, viral and protozoan diseases that are among the most common poultry diseases. Important factors to prevent waterborne diseases in broiler production are the protection of supply sources, water disinfection and the quality control of microbiological, chemical and physical characteristics. Water is an essential nutrient for birds and therefore quality preservation is fundamental for good herd performance. The farmer may prevent many...
