The helmeted guineafowl, Numida meleagris , is a member of the Galliformes (King & McLelland, 1975). This order includes the domestic fowl, Callus domeslicus , which has undoubtedly dominated research studies in poultry production generally. Many of the anatomical studies in birds have been carried out using the domestic fowl, with comparatively little mention of other genera. Although the genera in the Galliformes have very many similarities, few anatomical differences have been shown to exist. For example, Crowe & Crowe (1979) have found some striking differences between the blood supply to the head and neck of the guineafowl and the domestic fowl.
The guineafowl has become a popular poultry bird in Nigeria, and has been said to rank second to the domestic fowl, despite its seasonal breeding pattern. The further improvement of this genus in our poultry production has necessitated increased studies into its nutritional requirements, management procedures and disease prevalence. In line with this improvement is the need for anatomical data on the female reproductive organs as a basis for the breeding and selection programme. The aim of this study is to describe the macroscopic arterial blood supply to the reproductive organs of the guineafowl.  相似文献

The wild boar, Sus scrofa, is not a typical member of the Egyptian wild fauna, although it appears to have lived in the Nile Delta and other suitable regions in the north of the country. However, historic populations were probably of mixed origin, including feral domestic pigs. It is incorrect, as is sometimes still done, to include the wild boar in the iconographic bestiary of Ancient Egypt and assume that the domestic pigs of Ancient Egypt derive from local wild boars.  相似文献

This article examines flooding and resilience in two riverine systems in the premodern Eastern Mediterranean. Flooding represents a distinct type of short-term cataclysmic events (SCEs) because of its frequency and long-term predictability which facilitates societal adaptation. We discuss the sources for premodern floods and their limitations before surveying Mesopotamia and Ancient Egypt as case studies. Both societies are compared with regard to their environment and how it shaped local flood management practices. We argue that although floods caused short-term societal disruption in these societies, they also stimulated the reorganization and regeneration of economic resources. Both Mesopotamian and Egyptian societies systematically managed and mitigated their risks and were, in general, resilient to flooding events.  相似文献

The eggshells of the cormorant (Phalacrocorax carbo), domestic fowl (Gallus domesticus), gannet (Sula bassana), guinea fowl (Numida meleagris), greater flamingo (Phoenicopterus ruber), and shag (Phalacrocorax aristotelis) have been separated into two groups on the basis of the composition of their outer stratum. In the domestic fowl, guinea fowl and greater flamingo the outer stratum is an organic cuticle while in the sea-birds it is an inorganic cover rich in vaterite. The calcareous deposits on the membranes of eggs of the domestic fowl which are shell-less at oviposition have been shown to consist essentially of the vaterite form of calcium carbonate. Reasons for the occurrence of this polymorph of calcium carbonate are discussed with relation to the physiology of the birds.  相似文献

Dream interpretation was regarded by ancient peoples in Mesopotamia, Egypt, Greece, and Rome as an art requiring intelligence and, sometimes, divine inspiration. It became a motif in literature. It was treated as a science by philosophers and physicians. Dreams were thought to come either as clear messages, or as symbols requiring interpretation. In a method called incubation, the dreamer could sleep in a sacred place in expectation of a dream that would elucidate a problem for which the dreamer desired guidance. Dream-books listing images and their meanings were popular. Historians reported leaders' famous dreams that affected the course of events. Very few ancient writers were skeptical of dreams; Cicero was one. Dream interpretation was an honored profession with exponents such as Artemidorus of Daldis. Ancient dream traditions and beliefs can provide perspective for consideration of more recent theories of dream interpretation.  相似文献

The molluscan fauna of the Persian Gulf has recently been relatively well documented, yet there are few records of heterobranch sea slugs (opisthobranchs) from the Arabian parts and no report from the Iranian waters. Here we report for the first time the occurrence of one of these molluscs in the northern Persian Gulf (Bandar Abbas, Iran). Sacoglossan specimens were collected in association with the seaweed, Caulerpa sertularioides. Since morphological attributes were not adequately reliable for species identification, molecular approaches were carried out. Maximum-likelihood and Bayesian Inference analysis of partial DNA sequences of the mitochondrial cytochrome c oxidase subunit I (COI) locus were used for DNA barcoding of large-bodied specimens of Elysia. All Persian Gulf specimens were genetically confirmed as Elysia cf. tomentosa sp. 5, one of at least five morphologically similar but genetically distinct species in the taxonomically challenging and unresolved E. tomentosa complex. This species has previously been recorded only from Australia and Thailand and our finding adds another distant point to the geographic distribution of this species.  相似文献

Crow calls of red jungle fowl (Gallus gallus) were analyzed for the purposes of (a) determining the extent of commonality and variability of acoustic features within and between individual roosters, and (b) characterizing the modal crow call of this species. Comparisons were made between crow calls of jungle fowl and those of domestic fowl to assess the extent to which domestication has affected these motor patterns.  相似文献

Dynamics of Trade in the Ancient Mesopotamian "World System"   总被引:1,自引:0,他引:1  
Maritime trade in the Arabian Gulf connected Mesopotamia with societies in the Gulf and with the Indus during the Bronze Age. This article explores the Gulf trade in light of shifting consumption patterns and of various political forces at work within and between regions, in order to define the socioeconomic place of the trade in center-periphery relations. Through time the consumption of certain commodities, notably copper and grain, became deeply embedded in the changing political economies of Mesopotamian and Gulf societies, and the trade formed a basic economic dimension of center-periphery relations in western Asia. At the same time, other forces—political, military, and cultural—configured center—periphery relations in western Asia as deeply as the economic ones, and provided the context within which the trade occurred. Using the Gulf trade as an example, the article offers a framework for considering the political and cultural, as well as economic, character of ancient center-periphery systems.  相似文献

In species with duplicated major histocompatibility complex (MHC) genes, estimates of genetic variation often rely on multilocus measures of diversity. It is possible that such measures might not always detect more detailed patterns of selection at individual loci. Here, we describe a method that allows us to investigate classical MHC diversity in red jungle fowl (Gallus gallus), the wild ancestor of the domestic chicken, using a single locus approach. This is possible due to the well-characterised gene organisation of the ‘minimal essential’ MHC (BF/BL region) of the domestic chicken, which comprises two differentially expressed duplicated class I (BF) and two class II B (BLB) genes. Using a combination of reference strand-mediated conformation analysis, cloning and sequencing, we identify nine BF and ten BLB alleles in a captive population of jungle fowl. We show that six BF and five BLB alleles are from the more highly expressed locus of each gene, BF2 and BLB2, respectively. An excess of non-synonymous substitutions across the jungle fowl BF/BL region suggests that diversifying selection has acted on this population. Importantly, single locus screening reveals that the strength of selection is greatest on the highly expressed BF2 locus. This is the first time that a population of red jungle fowl has been typed at the MHC region, laying the basis for further research into the underlying processes acting to maintain MHC diversity in this and other species.  相似文献

Summary The domestic fowl is reported to be extremely resistant toE. coli endotoxemia. We reported (Merrill et al., 1978) that in our hands this species displayed a lowlevel sensitivity similar to that seen in mammals. The discrepancy between previous reports and our recent findings could result from 1) seasonal differences in the responses of the domestic fowl to endotoxemia, 2) the age and nutritional status of animals used in these various studies, and/or 3) the toxicity of the different endotoxins used. Since there is a paucity of information regarding seasonal influences on the responses of experimental animals to shock and trauma, we have extended our earlier studies (conducted in October, fall group) to each of the remaining seasons of the year.Overnight, fasted, unanesthetized white Leghorn roosters (N=38) weighing 2.44±0.6 kg were injected intravenously with anE. coli endotoxin suspension (2.5 mg/kg). A separate group of birds (N=8) were injected with 0.9% saline. Plasma glucose, lactate, corticosterone, arterial blood gases and pH and selected hemodynamic variables were monitored for 24h or until death. Only four of eleven endotoxemic fall birds survived 24 h (LD64). All winter birds (N=9) survived the challenge (LDO), while seven of nine spring and summer-challenged animals (N=9 each group) survived for 24 h (LD22 both groups). The preterminal hypoglycemia and progressive lactacidemia seen in similarly-challenged mammals did not occur in any group. Plasma glucose levels in the fall group (least resistant) were significantly lower than in all other groups. The winter group (most resistant) showed the highest glucose levels. Elevation of plasma corticosterone following the endotoxin challenge was greatest in the winter group and least in the fall group. Similar corticosterone increases were seen in the spring and summer groups. We conclude that resistance to endotoxemia in the domestic fowl is influenced by the season of the year and that such seasonal influences are reflected, in part, by circulating levels of glucose and corticosterone.  相似文献

The chicken lysozyme gene encodes a hydrolase that has a key role in defence, especially in ovo. This gene was resequenced in global chicken populations [red, grey, Ceylon and green jungle fowl (JF)] and related bird species. Networks, summary statistics and tests of neutrality indicate that although there is extensive variation at the gene, little is present at coding sites, with the exception of one non‐synonymous site. This segregating site and a further fixed non‐synonymous change between red JF and domestic chicken populations are spatially close to the catalytic sites of the enzyme and so might affect its activity.  相似文献

Excavations below the A.D. 79 destruction levels in two houses at the Roman town of Pompeii, Italy included programmes of sieving and flotation for the recovery of biological remains. In addition to the usual finds of charred plant material and bones representing crop processing or food waste, and mineralised remains from sewage, were numerous burnt offerings. Cones and seeds of stone pine, fruit such as fig and grape and nuts such as walnut and hazel were present in many of them. Some of the offerings contained burnt bone, with the heads and feet of cocks (male domestic fowl) being particularly well represented. There was some change in the plants and animals used for the burnt offerings with time. These offerings could be related to domestic worship described in literary sources and depicted as offerings on altars in Pompeiian wall paintings at shrines to the Lares (household gods). The burnt offerings resulted in the preservation by charring of fruit that are not usually burnt during their processing for consumption. They also presented a taphonomic problem because re-worked charred material from burnt offerings was likely to have been a major component of other charred assemblages from the sites.

In April 1978 a total of 26565 drosophilid flies were collected in Egypt. Of ten species five are new records for Egypt, while two previously reported Drosophila species were not found. Seven of the species belong to the genus Drosophila and are known to be partly, or wholly, domestic.For the first time Drosophila subobscura is reported from Egypt. The species was collected at low frequency in an orchard near Alexandria, and one specimen was trapped in a city park in Cairo. Judged from the gene arrangements of 41 males studied, Egyptian Drosophila subobscura seem likely to be derived from recent immigrants from the south coast of Asia Minor.  相似文献

An investigation (clinical, immunological and epidemiological) of the workers of various fowl-farms was carried out in various regions of Kazakhstan for a number for years; the sera of domestic fowl and birds was studied as well. On the basis of examination of 6264 persons the greatest percentage of ornithosis was revealed among the workers of the slaughter house and the shop for the processing of the fowl. Examination of 4749 sera of bird blood showed that the highest incidence of ornithosis was among doves and ducks (43.2 and 11.6%), and the least--in chickens (5.3%); there proved to be a direct relationship between the infection of man and birds. Thus, it was shown that domestic fowl and also doves served as the source of ornithosis infection; foci of ornithosis were revealed in a number of Kazakhstan regions as a result of these investigations.  相似文献

T he earliest appearance of the Hoopoe in history is a painting of the bird perching with other species on the št -bush ( Acacia nilotica Del.). This painting is on the walls of the tomb of Knumhotpe at Beni Hasan, Egypt, and dates from the XIIth Dynasty ( circa 1900 B.C.). A fine coloured drawing of this bird by Howard Carter has been published by the Egypt Exploration Society1. The Egyptian artist has rendered his subject well: it is fairly true to nature except that the tail is represented as forking. I have searched in vain for further pictures of this striking bird in other Egyptian paintings, and the supposed mention of it in a papyrus of the reign of Sety II ( c. 1205 B.C.) cannot be maintained. In this document the writer complains that his dates will not ripen, for they are attacked by three species of birds, in the morning, at noon and at eventide respectively. The late Sir Gaston Maspero identified the first of these birds with the Hoopoe, but as the bird is not frugivorous his identification cannot stand1.  相似文献

By a variety of electrophoretic procedures it has been found that Gallus gallus , whether as jungle fowl or as chickens, differs consistently from Sonnerat's jungle fowl, G. sonnerati , in three egg white proteins: G3 ovoglobulin, G2 ovoglobulin and glutamyl peptidase. The electrophoretic patterns of egg white hybrids between G. gallus and G. sonnerati are identical to those obtained after simpiy mixing the egg whites; there is no evidence for hybrid protein zones. Although Japanese data on serum amylase can be interpreted as indicating introgressive hybridization in the origin of the domestic fowl, so far the egg protein data are negative in this respect.  相似文献

The Green‐legged Partridgelike (GP) fowl, an old native Polish breed, is characterised by reseda green‐coloured shanks rather than yellow, white, slate or black commonly observed across most domestic breeds of chicken. Here, we investigate the origin, genetic relationships and structure of the GP fowl using mtDNA D‐loop sequencing and genome‐wide SNP analysis. Genome‐wide association analysis between breeds enables us to verify the genetic control of the reseda green shank phenotype, a defining trait for the breed. Two mtDNA D‐loop haplogroups and three autosomal genetic backgrounds are revealed. Significant associations of SNPs on chromosomes GGA24 and GGAZ indicate that the reseda green leg phenotype is associated with recessive alleles linked to the W and Id loci. Our results provide new insights into the genetic history of European chicken, indicating an admixd origin of East European traditional breeds of chicken on the continent, as supported by the presence of the reseda green phenotype and the knowledge that the GP fowl as a breed was developed before the advent of commercial stocks.  相似文献
