“…Guinea fowl yolks presented significantly greater (p < 0.001) βcarotene concentrations, approximately 6.75 and 6.94 times greater than those of chicken and quail egg yolks, respectively. These findings corroborated previous works by Onyenweaku et al (2018) who also reported higher vitamin A levels in guinea fowl yolks than in chicken, quail, or turkey yolks. Environmental factors such as feed materials and weather conditions likely contributed to this variation in β-carotene content (Minh et al, 2006;Franco et al, 2020;Goto et al, 2022).…”

The present work evaluated β-carotene content, colour (L*, a*, b*), and consumer preference for egg yolks from chicken, guinea fowl, and quail, sampled from intensive or semi-intensive rearing systems in Ghana. The β-carotene content of guinea fowl yolk was almost seven times greater (p < 0.001) than that of chicken and quail yolks. The yellowness of guinea fowl yolk (82.18; p < 0.01) was approximately 1.5 and 1.3 times greater than that of chicken and quail yolks, respectively. A consumer preference test showed a significantly greater score (5; p < 0.001) for guinea fowl than for the other egg types. The yellowness of egg yolks had strong positive relationship with β-carotene content (r = 0.943; p = 0.216) and consumer preference (r = 0.995; p = 0.064). Therefore, enhancing the yellowness of egg yolks on the Ghanaian market, especially those from chicken, could lead to increased egg consumption in Ghana.

“…The lowest Ca was 160.7 µg g -1 and the highest 1810.0 µg g -1 in egg yolk samples. Our measurements for Ca levels in turkey egg yolks and albumens were higher than those reported by Onyenweaku et al (2018). Calcium is a structural material in the yolk that makes the granular structure of the egg yolk compact insufficiently hydrated and poorly accessible to enzymes and provides effective protection against heat gelation and thermal denaturation (Anton, 2013).…”

Poultry eggs are not only a source of nutrients for embryonic development, but also one of the main sources of food for humans. The demand for turkey eggs is increasing day by day due to their functional properties such as supporting muscle and cell formation and being beneficial to the immune and digestive systems. In addition, it contains essential elements such as iron at a reasonable level, which is among the reasons for the consumer's preference. The data on the element content of free-range turkey eggs, which is such an ancient food, is very scarce. This study focused on determining various element content of freerange turkey egg yolk and albumen by inductively coupled plasma optical emission spectrometry (ICP-OES). Within the scope of the research, sodium (Na), potassium (K), calcium (Ca), phosphorus (P), iron (Fe), manganese (Mn), magnesium (Mg), copper (Cu), zinc (Zn), chromium (Cr), boron (B), aluminum (Al), and lead (Pb) levels were determined in turkey egg yolk (n=52) and albumen (n=52) samples. Phosphorus was the most concentrated element in both egg yolk and albumen. Element contents in yolks were higher than those in albumen, except Na, K, B, Al, and Pb. The element with the lowest concentration was Al in turkey egg yolks, while Mg was the lowest analyzed element in albumens. This study separately exhibited the element content of turkey egg consumers in their preference for egg yolk or albumen

“…It is a ground feeding bird, characterized by a very wide crown, filled with grey-blue bare skin topped by a prominent horn coloured bony casque (helmet) in red brown colour, a feature which is unique in the guinea fowl [45]. The commercial popularity of the Guinea fowl is on the increase; they are used as ornamental birds [26], pest control in crop farms [36], and dietary source of high protein [26,27]. Studies have also shown that the guinea fowl is relatively more resistant to endemic poultry diseases than the domestic fowl [17,35].…”

Hindlimb Skeletal Morphology of the Helmeted Guinea Fowl (Numida meleagridis)

et al. 2023

The Guinea fowl (Numida meleagridis) is a semi-domestic bird whose commercial popularity is on the increase. The gross anatomy of the hindlimbs of 8 helmeted Guinea fowls of equal sexes were studied. The pubic shafts were free, thus they did not fuse ventrally to form a symphysis. The ilium had a quadrilateral and roughly triangular pre and post acetabular wings, respectively. A conspicuous renal fossa was observed in the post acetabular wing. An incomplete concentric obturator foramen, lacking a caudal margin, was formed by the ventral border of the ischium and dorsal border of the cranial pubic shaft, while a prominent ischiopubic fissure was formed by the same bones, caudally. The incomplete concentric nature of the obturator foramen created a common space between it and the ischiopubic fissure. The femoral major trochanter was more proximal than the head, while the minor tro-chanter and the head were on the same horizontal level. The femur lacked a visible pneumatic foramen. The tibiotarsus had a prominent cranial cnemial crest. The fibular spine terminated at the tibia mid-shaft, leaving one interosseous space. An intertarsal sesamoid bone was identified, indicative of an adult skeleton. Crests and channels depicted the hypotarsus. Vascular foramen was identified in the distal extremity of the tibiotarsus. Digit I was oriented to the planter direction. These results, and others, were compared with those of other birds in the available literature, and some morpho-functional paradigm of the Guinea fowl hindlimb skeleton was established.
