An important economic goal of the poultry industry is to increase the productivity. However, the productivity of this industry is threatened by climatic, physical, and social stressors [7]. High temperature in poultry-house reduces feed intake, body weight gain and feed efficiency. Furthermore, high ambient temperature causes the release of corticosterone and catecholemines. Corticoids depress ...

The levels and composition of agricultural dusts are influenced by animal species, production strategy, housing type and ventilation efficiency. Agricultural dust within animal houses is complex and consists of feed particles, microbes and their products, dander, fecal matter, gases, metals and other organic and inorganic components. Livestock and poultry production facilities may be categorize...

VILLAGE POULTRY PRODUCTION IN THE SUDAN. A survey form provided by the Joint FAO/IAEA Division was used to collect data on village poultry production in the Sudan. The production system in the households was based on scavenging indigenous domestic chickens, at times accompanied by pigeons, guinea fowls, ducks or turkeys. The average flock size was 18.8 birds and included 44.3% hens, 10% cocks, ...

IntroductIon In the last half century, significant increases in the productivity of modern poultry stocks have been achieved for both the meat and the egg production sectors of the global poultry industry. Synergies have resulted from advances made in all the major activities of poultry management and housing, nutrition and ration formulation, applying poultry genetics knowledge in commercial b...

Analysis of field data collected over several years in three poultry housing systems (narrow caged-layer houses, high-rise caged-layer houses, and broiler-breeder layer houses) indicated that the baited jug-trap was a reliable method of sampling house flies, Musca domestica L.; sticky ribbons provided additional information on two other fly species. Relative frequency of house fly capture indic...

BACKGROUND A questionnaire survey was conducted to assess the biosecurity and other practices of backyard poultry holdings and knowledge and practices of poultry keepers following an outbreak of highly pathogenic avian influenza (H5N1) virus in poultry in Thimphu city area, Bhutan. RESULTS The study identified 62 backyard poultry holdings in 12 settlement areas, and the owners were subsequent...

The challenges and targets facing the world's poultry science community in the immediate future are reviewed in the context of meeting the dietary needs for animal protein of the world population. The prior need to provide for the increasing demand for cereals, oil seeds, and grain legumes for human consumption is assessed at having a reasonable chance of success. If this need is met, the requi...

The Joint FAO/IAEA Division of the International Atomic Energy Agency has initiated a coordinated research program (CRP) to improve family poultry production in Africa. The program assists 12 scientists working in National Agricultural Research Systems (NARS) during a period of five years with research in the subject. Regular research coordination meetings bring together all participants involv...
