An explicit construction of pairing-friendly hyperelliptic curves with ordinary Jacobians was firstly given by D. Freeman. In this paper, we give other explicit constructions of pairing-friendly hyperelliptic curves with ordinary Jacobians based on the closed formulae for the order of the Jacobian of a hyperelliptic curve of type y = x + ax. We present two methods in this paper. One is an analo...

Two breeds of chickens were used to develop reference family and detect QTLs affecting egg quality traits: cocks of a native Polish breed Green-Legged Partidgenous (GlP) and hens of Rhode Island Red (RIR). During the first 100 days of the laying period, the GlP hens lay about 40 eggs weighting on average 50 g, whilst the RIR flock laid 83 eggs with a mean weight of 60 g. QTL analysis of egg qua...

The chicken domestication process represents a typical model of artificial selection, and gives significant insight into the general understanding of the influence of artificial selection on recognizable phenotypes. Two Japanese domesticated chicken varieties, the fighting cock (Shamo) and the long-crowing chicken (Naganakidori), have been selectively bred for dramatically different phenotypes....

This study was carried out to determine the prevalence of haemoparasites in chickens (Gallus gallusdomesticus) slaughtered at Samaru Live Bird market Sabon Gari Local Government Area Kaduna State, Nigeria. A total 100 blood samples were collected from male and female chickensat point slaughter. The heparinized sample bottles transported Veterinary Protozoology Laboratory Faculty Medicine, Ahmad...
