The nation-wide distributed poultry industry is crucial to cover the growing protein demand of the population in Chile. In fact, the domestic production and consumption of eggs shows a straight-line increase during the past 10 years, with a particular preference for white eggs consumption. In terms of local production, there is not sufficient information about the levels and parameters related to the quality of eggs. In this context, the objective of the work was to describe in detail the internal and external quality of white eggs in a series of poultry farms in the central zone of Chile through the measurement of different quality parameters throughout the laying cycle of hens. Thus, eight producers have been requested to provide 15 white eggs in each of the following age ranges: 20, 40, 60, 80, 100 and 120 weeks. Findings confirmed significant statistical differences among producers for all the variables analyzed. Regarding the external quality attributes of eggs, it was found that, on average, the weight increased in the course of weeks from 52.27 g in week 20 to 65.57 g in week 80 and 64.4 g in week 100; decreasing afterwards to 62.41 g in week 120. Resistance to breakage decreased steadily from 4.53 kg in week 20 to 3.23 kg in week 120; and thickness of shells did not present any trend related with the age of hens, varying only 0.01 mm between the different weeks (0.40 mm - 0.41 mm). Concerning the internal quality parameters eggs, there is no pattern established regarding the height of albumin and the Haugh Units over time, since values of both variables decreased between weeks 20 to 60, then increased in 80 and 100, and finally decreased again in the last range of weeks (minimum values of albumin height and Haugh Units were 5.81 mm and 72.24 UH, and the maximum were 6.76 mm and 83.67 UH in height of albumin and Haugh Units, respectively). Likewise, there is no pattern defined in the pigmentation of yolk, starting at 8.57 (according to DSM “YolkFan” colorimetric range) and ending at 8.60. The results of weeks 100 and 120 of this study differ from findings described in literature, as the values of the variables decreased. However, they are expected to increase after the moult. Consequently, it was determined that there is no linear relationship between the variables of this study and the age of hens. There are clear differences between the values proposed by commercial manuals for each strain and the average of values obtained by producers who used them....

The aim of this study was to characterize the quality of the white shell egg in commercial poultry establishments in Chile and its relationship to certain factors of production, for which a sampling among the top 10 egg producers in the country was performed. Each participating company was requested to provide samples of eggs from hens of different ages, which were evaluated for weight and strength and thickness of the eggshell. In addition, the oyster shell used as a source of calcium in the diet of laying hens in various enterprises, in terms of particle size and calcium content was evaluated. The resulting data showed that egg weight increased along with the age of the birds, while the strength of their shells fell steadily. The eggshell thickness remained stable with increasing age across different companies. The relationship between the average of all participating establishments for different variables by linear regression and correlation coefficients were evaluated. It was further determined that the components with greater influence on the eggshell strength are its thickness, as well as the age of the hens together. As for the oyster shell particle size, was found that none of the participating egg producers meet the requirements proposed by the manuals of genetic lines used. However, it was possible to conclude that the calcium content of the oyster shell is relatively stable between samples given by the different companies....

año 2012 mientras que en Chile esta cifra superó los 89,1 kg el año 2013. En ambos casos, las carnes con mayor representación en el consumo fueron las prevenientes de ave y cerdo. En nuestro país la industria avícola concentra sobre el 46% de las...
Meat is an important food for the human population because it provides all the essential amino acids for the body and high bioavailability vitamins and minerals. The worldwide consumption of meat reached 42.9 kg per capita in 2012 while in Chile this cipher exceeded 89.1 kg in 2013. In both cases, the meats with greater representation in consumption were those from poultry and pork. In our country the poultry industry represented the 46% of total tonnage produced and the 85% of this meat was from broiler chicken for 2013. Although much of the meat poultry products were destined for internal consumption, the 16% were exported to Mexico, United States, China, Hong Kong and the European Union. The Food and Agriculture Organization of the United Nations and the World Health Organization agree that the responsibility of producing safe foods and suitable for consumption is distributed throughout all stages of the food chain, encompassing primary production, processing and trade activities. For this reason, the poultry industry must adopt rules and guidelines established by the Codex Alimentarius Commission in their production processes by implementing quality assurance systems, such as Best Production and Manufacturing Practices and the Hazard Analysis and Critical Control Points system. For primary production, Best Production Practices includes actions to ensure the safety and suitability of meat as well as to encourage a production that considers ethical aspects and modern consumer needs such as environmental protection, animal welfare, etc. Even though poultry industry possess a quality management system that incorporates a Manual of Best Production Practices for poultry farms developed in 2003, the guidelines proposed by this document may not be adequate to deal with the new challenges in food safety and quality. In order to update concepts of the Best Production Practices for the fattening of broiler chickens, a review of current recommendations and new approaches of reference organizations such as the Codex Alimentarius Commission as well as national and international institutions oriented to encourage the protection of consumer health, production efficiency, animal welfare, among other areas that have a direct impact on poultry meat quality was held. As result, the recommendations identified and agreed with the national poultry industry were incorporated into a new Manual of Best Production Practices for the fattening of broiler iv chickens, including eleven chapters that cover the following topics: infrastructure and facility design, biosafety, health and animal welfare, food and nutrition, food manufacturing, pest control, transportation, traceability, staff and communities....
