Some of the properties and the amino acid compositions of the histones of calf thymus, calf liver, fowl erythrocytes, and of a protamine-like material isolated from rooster sperm were described. The amino acid compositions of the histones were rather similar except that no methionine was found in the fowl erythrocyte histone. In the fowl, histones are found in the somatic chromosomes and protam...

After introducing the jeopardy card game Fowl Play, we present equations for optimal two-player play, describe their solution with a variant of value iteration, and visualize the optimal play policy. Next, we discuss the approximation of optimal play and note that neural network learning can achieve a win rate within 1% of optimal play yet with a 5-orders-of-magnitude reduction in memory requir...

data related to yazd native fowls (obtained during 2000-2008) yazd native fowls were made use of in the present study. the investigated traits consisted of body weight at 8 (bw8) and 12 weeks (bw12), age at sexual maturity (asm), egg number during the first three months of production period (en) and the mean egg weight at 28, 30 and 32 weeks of age (ew). the genetic and phenotypic parameters we...

the objective of the present study was to evaluate the genetic structure and diversity of 16 generations of native fowls of west azerbaijan province, iran using the pedigree data collected between 1994 and 2012. inbreeding coefficient (f), pedigree completeness index (pci), parameters of the probability of gene origin and other parameters related to the genetic structure were estimated using th...

Background and Aims: Inclusion body hepatitis (IBH) is one of the most important reemerging diseases in many countries with intensive poultry industries. In Iran, the etiological agent of IBH (fowl adenovirus) has not been yet confirmed. The aim of this study was the molecular detection and identification of fowl adenovirus involving IBH in chicken flocks in Iran. Materials and Methods: Polymer...

Fragmentation of the world's most intact forest landscapes will likely increase severity Human Wildlife Conflict (HWC). The way these threats affect top predators involves a series complex social and ecological relationships, which are not completely understood, thus require socio-ecological studies. aim this study is to examine factors that tolerance local people towards endangered Black-and-c...

To assess genetic diversity and maternal origin of Turkish and Iranian native chicken breeds, we analyzed the mtDNA D-loop sequences of 222 chickens from 2 Turkish (Denizli and Gerze) and 7 Iranian (White Marandi, Black Marandi, Naked Neck, Common Breed, Lari, West Azarbaijan, and New Hampshire) native chicken breeds, together with the available reference sequences of G. gallus gallus in GenBan...

The signal transduction pathways involved in the regulation of the acrosome reaction and motility of fowl spermatozoa were investigated. The motility and acrosomal integrity of fowl spermatozoa in TES/NaCl buffer, with or without homogenised inner perivitelline layers (IPVL), prepared from laid fowl eggs, was almost negligible at 40 degrees C. In the presence of 2 mmol CaCl(2)/l at 40 degrees C...
