Subject:
chicken eggs; egg weight; eggs; physical properties; simulation models
Abstract:
... An unusually popular index reflecting the quality of the egg contents and known as the Haugh unit (HU) score is empirical in nature. Because of that, a number of studies appeared that contradict or try to improve this index. In this regard, we set a study that pursued several goals: (i) to trace the rationale for developing the HU index and give it a theoretical reassessment; and (ii) based on the ...

Abstract:
... Egg volume and surface area are reliable predictors of quality traits for both table and hatching chicken eggs. A new non-destructive technique for the fast and accurate evaluation of these two egg variables is addressed in the present study. The proposed method is based on the geometrical transformation of actual egg contour into a well-known geometrical figure which shape most of all resembles t ...

Abstract:
... National nutrition surveys have shown that over half of all adults in Ireland, the United Kingdom (UK), and the United States of America (USA) have low vitamin K intakes. Thus, dietary strategies to improve vitamin K intakes are needed, and vitamin K biofortification of food may be one food-based approach. The primary aim of our study was to establish whether increasing the vitamin K₃ content of h ...

Given that erythropoiesis (blood production) can be equated with early embryonic growth rate, it was hypothesised that blood pigment haemoglobin can act as a specific spectral fingerprint for changes in growth rate. Moreover, by measuring longitudi ...

Abstract:
... Traditionally, the bioavailability of vitamin B-12 (B12) from in vivo labeled foods was determined by labeling the vitamin with radiocobalt (57Co, 58Co or 60Co). This required use of penetrating radioactivity and sometimes used higher doses of B12 than the physiological limit of B12 absorption. The aim of this study was to determine the bioavailability and absorbed B12 from chicken eggs endogenous ...
