We tested seven hypotheses regarding the mechanisms by which fluctuating asymmetry (FA) originates. We did this by analyzing data on four bilateral characters measured repeatedly during the development of individual domestic fowl. Immediately posthatching, there was substantial directional asymmetry, which rapidly decreased. We detected FA at significant levels in all characters in the majority...

Iranian native hens are a valuable genetic resource, due to their adaptability to harsh conditions of husbandry and environment in rural area. The genetic parameters for various traits of economic importance were studied in an Iranian Native chicken population under short term selection for egg production and body weight for over 2 years. The parameters studied were body weight at day old (BW1)...

Polymorphisms in 5’-flanking region of prolactin (PRL), exon 2 and exon 5 of prolactin receptor (PRLR) genesand its association with growth and egg traits were examined in breeder hens of Mazandaran native fowlsbreeding station. A single nucleotide polymorphism at site C-2402T and a 24 bp nucleotide sequence insertionat situation -382 in 5’-flanking regions of PRL gene were id...

enteritis due to campylobacter is the most common cause of acute bacterial diarrhea worldwide. in most cases, infection occurs as a result of consuming contaminated water or food, especially raw meat of fowls. campylobacters are saccharolytic and fastidious bacteria. these traits limit the number of available biochemical tests by which isolates may be differentiated. these limitations might, in...

AIM The red jungle fowl is generally considered as one of the endangered Asian wild Galleopheasants due to man-made encroachment of their habitats, coupled with the effect of disease and disease causing organisms like ticks and tick-borne infections. This study aimed to determine the tick fauna of the red jungle fowl and their predilection sites based on developmental stages. MATERIALS AND ME...

With the aim to establish the effect of the product Vemoherb-T (dry extract of Tribulus terrestris L) on egg yolk lipids and serum total cholesterol content, the trial was designed with 30 Pearl gray Guinea fowls, at the age of 32 weeks, randomly distributed in control and experimental groups, 12 female and 3 male each. All birds received the same mixture for breeder Guinea fowls. The tested pr...

Squamous-cell carcinomas, hemangiomas, fibro mas, and papillomas have occurred in the skin of ducks following the local application of a 0.25 per cent acetone solution of methylcholanthrene daily for a period of 1 month (5, 6). The spontaneous disappearance of a high per cent of these neo plasms in the duck has proved to be a feature of considerable interest (7). Attempts have been made infrequ...

Considering the importance of maintaining genetic diversity in native animals, this study conducted to analyse dromedary populations north Kerman province, Iran, using eight autosomal microsatellite markers. Eighty-one blood samples were collected from five different and DNA was extracted. The highest lowest allele number effective alleles shown YWLL08 (21 4) VOLP32 (14.97 3.11), respectively. ...
