Sexing in guinea fowls (Numida meleagris).
Despite the potentials and contributions of guinea fowls to economic and social life in Ghana, accurate sex identification in these birds is still a major problem. Three hundred and sixty guinea fowls (180 birds per sex) were used in determining a more accurate and farmer friendly sexing technique. The sexing methods explored were vent, biometric, and molecular techniques. Vent sexing was accom...
متن کاملMethods for Cryopreservation of Guinea Fowl Sperm
Conservation of indigenous poultry species is an important part of the new Hungarian agricultural strategy. Semen cryopreservation is the most practical method for the long term storage of poultry genetic material. The objective was to compare four protocols for cryopreservation of guinea fowl sperm (slow and fast programmable, freezing in nitrogen vapor, and pellet) and three cryoprotectants (...
متن کاملA comparative analysis of microbial profile of Guinea fowl and chicken using metagenomic approach
Probiotics are live microbial feed supplements that promote growth and health to the host by minimizing non-essential and pathogenic microorganisms in the host's gastrointestinal tract (GIT). The campaign to minimize excessive use of antibiotics in poultry production has necessitated development of probiotics with broad application in multiple poultry species. Design of such probiotics requires...
متن کاملNovel Avian Coronavirus and Fulminating Disease in Guinea Fowl, France
For decades, French guinea fowl have been affected by fulminating enteritis of unclear origin. By using metagenomics, we identified a novel avian gammacoronavirus associated with this disease that is distantly related to turkey coronaviruses. Fatal respiratory diseases in humans have recently been caused by coronaviruses of animal origin.
متن کاملIdentification and sequence analysis of Tapasin gene in guinea fowl
Aim: An attempt has been made to identify and study the nucleotide sequence variability in exon 5 exon 6 regions of guinea fowl Tapasin gene. Materials and Methods: Blood samples were collected from randomly selected birds (12 guinea fowl birds) and Tapasin gene amplified using chicken specific primers designed from GenBank submitted sequences. Polymerase chain reaction conditions were standard...
