متن کاملPoultry Egg Incubation: Integrating and Optimizing Production Efficiency
Due to its central position in the production chain, in-ovo development is influenced by pre-incubation factors that affect the quality of embryonated eggs and incubation conditions themselves, and both may influence egg hatchability and chick quality, as well as bird survival, growth performance, and phenotype in the field. The evolution of the incubation process over the years is characterize...
متن کاملIssues Concerning Food Safety in Poultry and Egg Production: Issues Concerning Salmonella and Campylobacter in Poultry Symposium
Four or 5 decades ago one of the main concerns was to extend the shelf life of refrigerated processed poultry. Some Salmonella analyses were done but primarily indicator organisms were used. At that time Campylobacter were not yet recognized as a foodborne (poultryborne) enteropathogen. At present, both of these microorganisms are routinely tested for both by cultural and rapid, high tech metho...
متن کاملAnimal model estimation of additive and dominance variances in egg production traits of poultry.
An animal model analysis was used to estimate simultaneously additive (sigma 2a) and dominance (sigma 2d) variances for egg production traits within three White Leghorn lines. The data consisted of information for three generations on egg number (EN) produced at 18 to 25 (EN1), 26 to 65 (EN2), and 18 to 65 wk of age (EN3); egg weight (EW) measured at 30 to 35 (EW1) and 40 to 45 wk (EW2); and eg...
متن کاملEvaluation of egg production after adoption of biosecurity strategies by backyard poultry farmers in West Bengal.
AIM On the basis of identified source of major bacterial infections at four agro-climatic zones in West Bengal the cost-effective biosecurity strategy was formulated for backyard poultry farmers. The aim of the present study was to assess the adoption. So, the study was aimed to detect the adoption level of the formulated biosecurity strategy to mitigate the Salmonella and Escherichia coliweek ...
