Effect of pearl guinea fowl eggshell ultrastructure and microstructure on keets hatchability. [PDF]

Poult Sci, 2023
Variability in shell structure is an evolutionary mechanism in birds that enables them to adapt to specific environmental conditions. This variability may also occur within the same species under the influence of individual indicators, such as the age or

Photoperiodic-dependent histomorphological changes in the excurrent duct system of helmeted guinea fowl subjected to short day (8L:16D), long-day (16L:8D) light/dark cycles and exogenous melatonin. [PDF]

Vet Anim Sci, 2023
Highlights • Therein, we have investigated the potential influence of varying photoperiods (short-day 8L: 16D) and long-day (16L: 8D) artificial lights and exogeneous melatonin on the excurrent duct system (i.e., epididymis and ductus deferens) of ...

Genomic Analyses of Unveil Helmeted Guinea Fowl (Numida meleagris) Domestication in West Africa. [PDF]

Genome Biol Evol, 2021
Domestication of the helmeted guinea fowl (HGF; Numida meleagris) in Africa remains elusive. Here we report a high-quality de novo genome assembly for domestic HGF generated by long- and short-reads sequencing together with optical and chromatin ...
