Abstract:

The aim of the present study is to characterize the productive capability of Utrerana and to compare the relationships among parameters determining the internal and external quality of the egg, through canonical correlation analysis. A flock of 68 Utrerana hens and a control group of Leghorn hens (n = 17) were housed individually to allow individual identification of eggs and for the assessment of egg quality characteristics. Almost all variables showed differences when both breeds were compared, except for white height, yolk diameter, yolkL* and yolk pH (p > 0.05). Only minor diameter, whi

This study aimed to develop a tool to validate multivariety breed egg quality classification depending on quality-related internal and external traits using a discriminant canonical analysis approach. A flock of 60 Utrerana hens (Franciscan, White, Black, and Partridge) and a control group of 10 Leghorn hens were placed in individual cages to follow the traceability of the eggs and perform an individual internal and external quality assessment. Egg groups were determined depending on their commercial size (S, M, L, and XL), laying hen breed, and variety. Egg weight, major diameter, minor diame

Abstract:

Herein we examined the effects of yolk size and ovulation order on the fertilisation of yolks within double-yolked (DY) duck eggs. Single-yolked (SY) duck eggs had high fertility (89.98%), whereas in DY duck eggs fertility was low (51.9% yolks). The yolks closer to the airspace (Yolk 1) in DY eggs had higher fertility (68.82% vs 34.98% for Yolk 2; P < 0.001). When only one of the two yolks was fertilised, Yolk 1 was fertilised in 99.12% of those eggs. Yolk 1 is presumed to be the first ovulated. The higher fertility of Yolk 1 is consistent with a primacy effect where the first ovulation has

Abstract. In this work the cholesterol content of chicken eggs produced by two lines (high and low weight) representing the 31st generation of selection for divergent growth was studied. Divergent selection for body weight at 8 weeks of age resulted in changes in egg size and consequently in the weight of egg components. Higher values (P≤0.001) were observed in eggs from the high weight (D+) line for egg weight, albumen, yolk and shell weight. Percent yolk was greater (P≤0.001) and percent albumen was lower (P≤0.001) in eggs from the low weight (D−) line. Eggs from the D− line contained lower

Color also is a major sensory factor that helps consumers determine food quality and its possible health benefits. For example, highly colored egg yolks can only come from healthy laying hens fed a well-balanced, nutrient-rich diet. Consumers associate an intense yolk color with healthy, nutrient-rich food. There is a growing market request for eggs with rich yolk coloring. The purpose of the current study was to evaluat

ISA Brown hens were fed diets supplemented with the synthetic carotenoids Carophyll Red and Carophyll Yellow at 20 and 15 mg/kg, respectively, lutein at 250 mg/kg, and the algae Chlorella at 12.5 g/kg. The synthetic carotenoids, lutein, and Chlorella significantly increased egg weight (P &lt; 0.001), shell weight (P&nbsp;&lt; 0.001), and thickness (P = 0.017) and decreased the yolk/albumen ratio (P = 0.035) of the eggs. Lutein but not the Carophylls or Chlorella significantly increased the shell breaking strength (P = 0.032). Furthermore, the carotenoids and Chlorella significantly

Characteristics are presented on eggs of the maleo, Macrocephalon maleo, which are compared with data from other megapodes. Maleo eggs contain an extremely large amount of yolk which, on average, accounts for 61.9% of the egg contents weight, which is much higher than in eggs of the Australian brush-turkey, Alectura lathami (50.1%), and the malleefowl, Leipoa ocellata (52.6%). A higher yolk content leads to an elongation of the egg and a higher relative egg weight. The results suggest that eggs of burrow-nesting megapodes contain more yolk than eggs of mound-building species.
