The histogenesis of the primordial oesophagus was studied to determine the period in which the tunics of the oesophagus developed and became functional in the helmeted guinea fowl (Numida meleagris). Eighteen embryos and nine keets were studied at prehatch and posthatch, respectively. Simple columnar epithelium surrounded by mesenchymal cells was obvious at the 8th day of embryonic development. By the 19th day of embryonic development, the four tunics, tunica mucosa, submucosa, tunica muscularis, and tunica adventitia/serosa, were beginning to differentiate from the mesenchymal cells and also the primordial oesophageal glands appeared as clusters of cells that invaginate from the epithelium. By the 27th day, the tunics were clearly differentiated and the primordial glands were fully developed as evident with positive reaction to Periodic Acid Schiff (PAS). The tunics of the muscularis were not well developed till at posthatch. This study therefore concludes that the primordial oesophagus is active at the late incubation due to mucin secretion by mucous glands but fully functional at posthatch since the tunica muscularis is completely developed at posthatch.

The Impact

This study was undertaken to determine the impact of seasonal variations and different dietary protein levels on production traits, reproductive performance and egg characteristics of Guinea fowl (Numida meleagris) in the Middle belt of Ghana. Twelve (12) males and forty-eight (48) females Pearl Guinea fowls of 12 weeks of age were subjected to isocaloric diet containing 16%, 18%, 20% and 22% crude protein levels.Each group was replicated three times and reared in three seasons (Dry-December-March, Major rains-April-July and Minor rains-August-November) in a 3x4 factorial experiment. Data were analyzed using General Linear Model procedure of SAS.Hen day egg production (HDEP) and egg mass increased (p<0.05), but feed intake, feed conversion ratio, egg weight, fertility and hatchability of incubated eggs were not significantly different (p>0.05) with increasing dietary protein. Egg quality traits did not differ significantly (p>0.05) except egg yolk (p<0.05). Season showed positive (p<0.05) relationship with all production traits as well as fertility of incubated eggs, but not hatchability (p>0.05). Egg internal and external traits were significantly (p<0.05) influenced by season except yolk weight and shell weight (p>0.05).Results demonstrates that increasing dietary protein promoted egg production and reproductive traits in Guinea fowl, nevertheless, 16% crude protein diet is sufficient to support optimum egg production, fertility and hatchability, and egg characteristics. Rainy seasons countenance production traits, fertility and hatchability as well as egg characteristics, thus, breeding should be planned to take advantage of the major rainy season.

Abstract Domestication of the helmeted guinea fowl (HGF; Numida meleagris) in Africa remains elusive. Here we report a high-quality de novo genome assembly for domestic HGF generated by long and short-reads sequencing together with optical and chromatin interaction mapping. Using this assembly as the reference, we performed population genomic analyses for newly sequenced whole-genomes for 129 birds from Africa, Asia, and Europe, including domestic animals (n = 89), wild progenitors (n = 34), and their closely related wild species (n = 6). Our results reveal domestication of HGF in West Africa around 1,300-5,500 years ago. Scanning for selective signals characterized the functional genes in behavior and locomotion changes involved in domestication of HGF. The pleiotropy and linkage in genes affecting plumage color and fertility were revealed in the recent breeding of Italian domestic HGF. In addition to presenting a missing piece to the jigsaw puzzle of domestication in poultry, our study provides valuable genetic resources for researchers and breeders to improve production in this species.

Pathogenic Effects

SummaryEimeria grenieri was isolated from intensively reared guinea fowl in Britain. The oocysts had average dimensions of 21·09 × 15·48 μm and a small micropyle. Three generations of schizonts were found in the small intestine. The first mature schizonts were found in the upper intestine 30 h after inoculation. Second-generation schizonts were seen 48–80 h and third-generation schizonts were present 80–96 h after inoculation. These schizonts were found in the middle and lower small intestine. It was confirmed that gametogony of this species occurs only in the caeca. The pre-patent time was 112 h and the reproductive index from a dose of 6 × 102 oocysts was 8 × 104. Doses of between 1 × 104 and 1 × 106 caused severe depression of body weight gain. Immunity to re-infection developed rapidly. Sulphaquinoxaline at a dose of 0·04% in the drinking water given after inoculation was effective in reducing the pathogenic effects of the disease. Robenidine given in the food at a concentration of 16·5 ppm (50% of the recommended concentration for chickens) was effective in preventing disease caused by E. grenieri.The endogenous life-cycle of E. grenieri was completed in the chorioallantoic membrane of developing chicken embryos.

<p class="jbls-body"><span lang="EN-GB">A total of one hundred and seventy-three fertilized eggs were used for morphometry, gross and histological studies. At day 4 of incubation, the mean body weight of the helmeted guinea fowl embryo was 0.6401 ± 0.0211 g. It was at day 10 of incubation that there was an increase in the whole body weight of the embryo to be 0.8650 ± 0.676 g. The whole brain weight indicated relative increased at day 4 as compared to that of the whole body weight. Graphically, there were steady increase in the body, brain and optic lobe weights. Histologically, cells and neurones that make up the optic lobe is probably as a result of the migration of immature cells from the ventricular neuroepithelium. </span></p>
