Logistic regression to estimate the welfare of broiler breeders in relation to environmental and behavioral variables
Provedor de dados: 70
Autores: Pereira,Danilo F; Oliveira,Sandra C. de; Penha,Nárima L. J.
The increasing demand of consumer markets for the welfare of birds in poultry house has motivated many scientific researches to monitor and classify the welfare according to the production environment. Given the complexity between the birds and the environment of the aviary, the correct interpretation of the conduct becomes an important way to estimate the welfare of these birds. This study obtained multiple logistic regression models with capacity of estimating the welfare of broiler breeders in relation to the environment of the aviaries and behaviors expressed by the birds. In the experiment, were observed several behaviors expressed by breeders housed in a climatic chamber under controlled temperatures and three different ammonia concentrations from...

The Potential Effects on United States Agriculture of an Avian Influenza Outbreak
Provedor de dados: 31
Autores: Brown,   Scott; Madison,   Daniel; Goodwin,   Harold L., Jr.; Clark,   F. Dustan.
The U.S. poultry industry has spent considerable resources to date preparing for an outbreak of avian influenza in this country. This research quantifies the potential effects of two alternative avian influenza scenarios on the poultry industry. In addition, this research looks at effects on other agriculture sectors including the loss of feed demand from an outbreak and the impacts on aggregate measures like farm income and consumer food expenditures. The economic sector model maintained by the Food and Agricultural Policy Research Institute (FAPRI) is employed for these scenarios.

How Highly Pathogenic Avian Influenza (H5N1) Has Affected World Poultry-Meat Trade
Provedor de dados: 31
Autores: Taha,   Fawzi A.
In 2003, outbreaks of the highly pathogenic avian influenza (HPAI) H5N1 virus had a major negative impact on the global poultry industry. Initially, import demand for both uncooked and cooked poultry declined substantially, due to consumers’ fear of contracting avian influenza by eating poultry meat. Consumer fears adversely affected poultry consumption in many countries, leading to lower domestic prices, decreased production, and lower poultry meat exports. These reductions proved to be short-lived, as prices, consumption, production, and exports returned to preoutbreak levels in a relatively short time. As consumers gained confidence that poultry was safe if properly handled and cooked, world demand for cooked poultry increased. The cooked poultry share...

Agricultural Household Response to Avian Influenza Prevention and Control Policies
Provedor de dados: 31
Autores: Beach,   Robert H.; Poulos,   Christine; Pattanayak,   Subhrendu K.
Recent outbreaks of highly pathogenic avian influenza in Asia, Europe, and Africa have caused severe impacts on the poultry sector through bird mortality and culling, as well as resulting trade restrictions and negative demand shocks. Although poultry producers play a major role in preventing and controlling avian influenza, little research has examined the influence of their farm-level decision making on the spread of the disease. In this study, we describe farm behavior under livestock disease risk and discuss data and analyses necessary to generate sound empirical evidence to inform public avian influenza prevention and control measures.

Location of Production and Consolidation in the Processing Industry: The Case of Poultry
Provedor de dados: 31
Autores: Goodwin,   Harold L., Jr.
The poultry industry is the most vertically integrated of U.S. agriculture and food production and is rapidly progressing toward being one of the most concentrated.  In 2002, the top 15 broiler states accounted for 94.4% of U.S. production.  From 1982-2002, the top four broiler firms had a fivefold increase in Ready-to-Cook (R-T-C) pounds, a tripling of plants and four-and eight-firm concentration ratio increases of 27.9% to 48.2% and 44.1% to 66.6%.  In a broad sense, chicken became more affordable, appealing, and available; total R-T-C pounds increased from 234 to 663 million pounds between 1982 and 2002.

Autores: Nyars,   Levente.
Magyarország földrajzi fekvése miatt a fehérjeforrások beszerzési költségei magasabbak és a baromfihúsexport is költségesebb a szállítás miatt, de a fűtési és hűtési költségek is magasabbak, mint például Hollandiában, Brazíliában. A globalizáció kihívásai elől a magyar baromfiágazat sem térhet ki. Az árversenyben a nagy kapacitások, az olcsó munkaerő és az olcsó takarmány nagy előnyt jelent. A magyarországi alapanyag-termelés helyzetét nehezíti, hogy a gazdaságok döntő része nem rendelkezik földterülettel, vagyis nem képesek megtermelni a takarmányt, és gondot okoz a keletkezett trágya elhelyezése is. A hazai vágócsirke-termelés középtávon 230 ezer tonna körül alakul. A magas takarmányárak, valamint a „nem-termelő” beruházások költségvonzata miatt a hazai...

Mass Balance Applied to Brazilian Conventional Broiler Houses during One Production Cycle
Provedor de dados: 89
Autores: Migliavacca,A; Yanagihara,JI.
ABSTRACT Brazil plays an important role in global poultry production as it is the world's largest chicken exporter and the third largest broiler producer. Despite the development achieved by the Brazilian broiler industry as a result of the integrated production system, many obstacles still need to be overcome, in particular, housing environment. In this regard, detailed knowledge of the inputs, outputs, and primary waste generated by broiler production cycles is essential to establish a baseline for energy balance research studies and to develop environmental solutions. This article proposes a mass balance of conventional broiler houses of southern Brazil sheds in order to predict their outputs, but that may also be applicable to other regions with...

Photogrammetry: a Non-Invasive and Objective Method for Detecting Locomotion Problems in Broiler Chickens
Provedor de dados: 89
Autores: Mendes,AS; Paixão,SJ; Sikorski,RR; Bonamigo,DV; Morello,MG; Ponzoni,RAR.
ABSTRACT Locomotion problems in broiler chickens can cause economic losses of up to 40% of the total revenues due to carcass condemnation and downgrading at processing. Leg disorders, such as femoral lesions, tibial dyschondroplasia, and spondylolisthesis, substantially impact the welfare of chickens as these disorders can prevent birds from reaching the feeders and drinkers, thus reducing feed and water intake. The most important issues related to broiler welfare reported in the last two decades are their growing sensitivity to metabolic and locomotion problems due to the fast growth rates and inactivity. Traditional methods for the determination of gait score include the manual scoring of animal behavior in the broiler house. Recorded video images can...

Locomotion deficiencies in broiler production cause poor welfare and lead to change in drinking and feeding behavior with consequent loss in weight gain. This research aimed to assess locomotion deficiencies in broiler chicken by analyzing the vertical peak force on both feet during walk. A chamber was built with an inlet ramp, a horizontal walkway in the middle and an outlet ramp. In the walkway a thin mat with piezoelectric crystal sensors was placed to record the step vertical peak force of the feet while walking on the force platform. The measurement system consisted of a mat with electronic sensors and software that allowed real time recording of the forces and the processing and analysis of data. Footage was taken from two digital video cameras and...

Animal-based agriculture, phosphorus management and water quality in Brazil: options for the future
Provedor de dados: 63
Autores: Shigaki,Francirose; Sharpley,Andrew; Prochnow,Luís Ignácio.
Eutrophication has become a major threat to water quality in the U.S., Europe, and Australasia. In most cases, freshwater eutrophication is accelerated by increased inputs of phosphorus (P), of which agricultural runoff is now a major contributor, due to intensification of crop and animal production systems since the early 1990s'. Once little information is available on the impacts of Brazilian agriculture in water quality, recent changes in crop and animal production systems in Brazil were evaluated in the context of probable implications of the fate of P in agriculture. Between 1993 and 2003, there was 33% increase in the number of housed animals (i.e., beef, dairy cows, swine, and poultry), most in the South Region (i.e., Paraná, Rio Grande do Sul, and...
