The exploitation of industrial strains chickens in the Sahelian climate Niger is characterized by a decline performance and significant costs associated with their maintenance. In contrast, local are well adapted to these environmental conditions but poor production performance. Genetic selection could improve productivity. first step determine if genetic parameters growth high enough ensure su...

An investigation was conducted to study the haematological parameters of Nigerian local chicken using a total 100 chickens out which 30 were randomly selected for bleeding. The blood samples subjected laboratory analysis identify their haemoglobin contents, fragility and sedimentation rates as well red cell counts, white counts coagulation time. results indicated that content ranged from 63.82 ...

chicken anemia virus was detected by pcr in tissue samples collected from poultry flocks in gujarat,india. the vp1, vp2 and vp3 gene sequences of cav from anand, gujarat were obtained after cloning thepcr products in pdrive cloning vector. nucleotide sequence alignment with other cav sequencesdemonstrated overall identity of 95-98.8%, 98.8-99.8% and 98.8-100% for vp1, vp2 and vp3 regions,respec...

The study was aimed at evaluation of the applicability of selected microsatellite markers in examining genetic diversity in five Polish local chicken varieties (two groups of native crested chickens, crestless native chickens from Subcarpathian region and two groups of native miniature chickens) and reveal their genetic relationships to five purebreds (Leghorn, Rhode Island Red, Sussex, Greenle...

BACKGROUND Crossed beaks have been reported to occur in Appenzeller Barthuhn, a local Swiss chicken breed. The assumed causes for this beak deformity which are also seen in other bird species including domestic chickens, range from environmental influences to genetic factors. The aim of this project was to characterize the prevalence, the phenotype, and the underlying genetics of crossed beaks ...

Development of an in vitro Eimeria (E.) tenella model could be valuable as a tool for vaccine, coccidiostats or molecular biology research. 1.0 × 10,000 sporozoites per 0.1 mL were inoculated into the allantoic cavity of ten-day-old chicken embryos. The complete life-cycle of E. tenella was accomplished in eight-nine days at 37 °C and 70% humidity. The addition of 100 U insulin to the embryos c...
