background: the loop pattern of the small intestine is of considerable importance in categorizing them and the intestine length of the two sex is different. in this respect there is no research performed on pheasant family as guinea fowl. objectives: in this research histomorphology of guinea fowl's small intestine was studied. methods: for this study 20 adult male and female guinea fowls ...

Acute pulmonary edema, splenomegaly, and ascites were observed in a disease outbreak in adult white and pearl guinea fowl. The clinical history and gross and microscopic lesions resembled those described for marble spleen disease of pheasants and avian adenovirus group II splenomegaly of chickens. A small number of intranuclear inclusion bodies were found in liver, spleen, and lung sections of ...

Studies with captive fowl have revealed that they possess greater cognitive capacities than previously thought. We now know that fowl have sophisticated cognitive and communicative skills, which had hitherto been associated only with certain primates. Several theories have been advanced to explain the evolution of such complex behavior. Central to these theories is the enlargement of the brain ...

This study was undertaken to describe the growth pattern of the pearl gray Guinea fowl. Using BW data from hatch to 22 wk, 3 nonlinear mathematical functions (Richards, Gompertz, and logistic) were used to estimate growth patterns of the pearl gray guinea fowl. The logistic and Gompertz models are a special case of the Richards model, which has a variable point of inflection defined by the shap...

The luminance dependence of spatial acuity in domestic fowl was measured directly over stimulus luminances ranging from 0.06 to 57.35 cd m(-2). At the highest luminance, acuity was around 6.5 c deg(-1), in agreement with previous studies in this species. As stimulus luminance decreased, acuity fell with increasing rate to 3.2 c deg(-1) at 0.06 cd m(-2), following the same shape as acuity functi...

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...

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...

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...
