摘要

动物遗传资源(AnGR)对所有未来的发展和适应都很重要。这一概念具有保护家畜某些特征以供可持续和未来利用的国际义务。土着番鸭(Cairina moschata)的特征将为AnGR提供信息,也有助于鸭的保护以供将来使用。从尼日利亚中北部5个地理位置获得的200只麝香鸭使用了质量性状、生理参数、血液谱和数量性状进行了鉴定。结果表明:研究区有52.50%、54.00%、51.50%、50.00%、45.00%和35.50%的番鸭体毛、腿、喙、腹、眼、豆呈黑色;50.00%为水平体架,90.50%为掌蹼型,95.00%为无冠型,62.50%为痈型。公鸭和母鸭存在性别二态性,公鸭性别和产地差异显著(p0.05)。不同产地鸭的体重、鸭腿直径、龙骨和翼长以及白细胞、淋巴细胞、红细胞和平均红细胞血红蛋白浓度、血小板和葡萄糖含量差异均显著(p>0.05)。所得信息可为研究地区番鸭的保护和改良育种策略的制定提供指导。

Phenotypic, Physiological and Blood Profile Characterization of Muscovy Ducks (Cairina moschata) In North Central Nigeria
Animal genetic resources (AnGR) are important to all future developments and adaptations. The concept has an international obligation to conserve certain characteristics of domestic animals for sustainable and future use. Characterization of indigenous Muscovy duck (Cairina moschata) would provide information for AnGR and also aid in conservation of ducks for future use. Two hundred (200) Muscovy ducks obtained from five (5) geographical locations in North central Nigeria were characterised using qualitative traits, physiological parameters, blood profile and quantitative traits. The results showed that 52.50, 54.00, 51.50, 50.00, 45.00 and 35.50% of the Muscovy ducks in the study area had black colour with respect to their general body plumage, shank, bill, web, eye, and bean, respectively. 50.00% were of horizontal body carriage, 90.50% had palmate web type, and 95.00% had no crest while 62.50% had caruncles. Sexual dimorphism existed between male and female with drakes having significantly (p<0.05) higher values compared to ducks in all the quantitative traits measured. Physiological parameters were not significantly (p>0.05) different according to sex and origin of the Muscovy duck studied. Comparison of the ducks by origin showed significant (p>0.05) differences in body weight, shank diameter, keel and wing length, and also in white blood cells, lymphocytes, red blood cells and mean corpuscular haemoglobin concentration, platelets and glucose. The information obtained here can serve as a guide on decisions concerning the conservation and development of selective breeding strategies for improvement of Muscovy ducks in the studied area.
