The purpose of this study was to analyze the associations among fluctuating asymmetry, duration of tonic immobility, heterophil-to-lymphocyte ratio, and one-legged standing, crooked toes, or footpad dermatitis in chickens. In experiment 1, cocks (n = 96; 36 wk old) from 11 Spanish breeds and a White Leghorn population that showed one-legged or normal standing were used. There were no significan...

Genetic adaptation and response to selection depend on genetic variation within and between populations, whereas characterization of the population is a first step towards its improvement. This study demonstrates that variation in genotypes observed in reproductive performance observed among the Nigeria indigenous chicken under the tropical ambient temperature could be explained by the differen...

The seasonal influence on the seminal characteristics of Shikabrown breeder cocks was evaluated weekly during the three seasons in Northern Guinea Savannah zone of Nigeria. Semen samples were analyzed by gross and routine laboratory methods for volume, motility, concentration, colour, percent dead and percent total abnormality. The highest volume and concentration values of 0.50±0.03ml and 3.60...

Three approaches are currently used for devising identity-based encryption schemes. They build on pairings, quadratic residues (QR), and lattices, respectively. Among them, the QR-based scheme proposed by Cocks in 2001 is notable in that it works in standard RSA groups: its security relies on the standard quadratic residuosity assumption. But is has also a number of deficiencies, some of them h...

The aim of this study was to propose equations to predict changes that occur over time in the angular position of the bones during motion and the angular velocity of the bones in forward motion as a consequence of tibiotarsal rotation (TTR) in ostriches aged 14 months. Twenty-four normal 14-month-old ostriches (12 cocks and 12 hens) and 20 birds with TTR (9 cocks and 11 hens) were used in the s...

The experiment aimed to study the influences of drinking natural saline water on thermoregulation, blood constituents and semen quality of White Leghorn cocks under heat stress in desert conditions. A total number of 60 cocks (22-wk-old and body weight of 1555 g ± 36.11) were divided randomly into four equal groups which in turn divided randomly into three equal replicates. The 1 st treatment (...

The Cocks Identity Based Encryption (IBE) scheme, proposed in 2001 by Clifford Cocks, has been the standard for Quadratic Residue-based IBE. It had been long believed that this IBE did not have enough structure to have homomorphic properties. In 2013, Clear, Hughes, and Tewari (Africacrypt 2013) created a Cocks scheme derivative where they viewed ciphertexts as polynomials modulo a quadratic. W...

Twenty healthy ostriches (ten cocks and ten hens), and twenty birds with tibiotarsal rotation (nine cocks and 11 hens) (14 months old) were isolated, hooded and weighed. A run (50 m x 2.5 m) was divided into sections marked 5 m, 10 m, 15 m and 20 m. Time taken for each bird to pass these points was recorded and speed computed. The degree of tibiotarsal rotation in the right foot was mean +/- SE...

Exposing a pregnant mammal to stressors causes behavioral and physiological alterations in her offspring ("prenatal stress"); however, elucidation of the underlying mechanism is hindered by an inability to control maternal compounds that may affect the fetus. We designed this experiment to determine if the autonomously developing chicken embryo could be developed as a model for prenatal stress....
