PHENOTYPIC VARIATION OF SOME QUALITATIVE TRAITS IN WEST AFRICAN DWARF GOATS
Description
Each class of livestock has some peculiar qualitative traits and in goats some of these are coat pigmentation, horned/polled, beard/non-beard, wattled/non-wattled. Since the impact of environment is important in phenotypic expression of qualitative traits, it becomes expedient to examine these features in West African Dwarf Goats (WADG) from every climatic region of the world. To accomplish this, a total of 623 WADGs aged between 3 and 4 years reared extensively in Ekiti state region of Nigeria were purposively selected from the three agricultural zones in the state for the examination. Data were collected on coat pigmentation, horns, wattle and beard on sex basis. The commonest pigmentation was black at 31.29%, 35.43% and 34.18% in the three zones and the least encountered was mixed pigmentation at 11.66%, 07.62% and 08.44% respectively. The number without wattles (57%) outnumbered those with wattles (43%). 88% had no beards and 87% were horned. 30% of does had wattles and 59% were horned as against 13% and 29%, respectively in bucks. In all, 2% of doe and 9% of buck had beards. The levels of variation in the traits surveyed in the three Districts indicated that WADGs in the region are predominantly black, not wattled, not bearded and horned.

كل فئة من الماشية لديها بعض الصفات النوعية الغريبة وفي الماعز بعض هذه هي تصبغ المعطف، قرنية/استطلاعية، لحية/غير لحية، مغمورة/غير مغمورة. نظرًا لأن تأثير البيئة مهم في التعبير الظاهري للسمات النوعية، يصبح من المناسب فحص هذه الميزات في الماعز القزم في غرب إفريقيا (WADG) من كل منطقة مناخية في العالم. ولتحقيق ذلك، تم اختيار ما مجموعه 623 من المجموعات الزراعية العاملة التي تتراوح أعمارها بين 3 و 4 سنوات والتي ترعرعت على نطاق واسع في منطقة ولاية إيكيتي في نيجيريا عن قصد من المناطق الزراعية الثلاث في الولاية للفحص. تم جمع البيانات عن تصبغ المعاطف والقرون والقرون واللحية على أساس الجنس. كان التصبغ الأكثر شيوعًا هو الأسود بنسبة 31.29 ٪ و 35.43 ٪ و 34.18 ٪ في المناطق الثلاث، وكان التصبغ الأقل شيوعًا هو التصبغ المختلط بنسبة 11.66 ٪ و 07.62 ٪ و 08.44 ٪ على التوالي. فاق عدد الأشخاص الذين ليس لديهم لحية (57 ٪) عدد الأشخاص الذين لديهم لحية (43 ٪). 88 ٪ ليس لديهم لحية و 87 ٪ قرون. 30 ٪ من الأشخاص الذين لديهم لحية و 59 ٪ قرون مقابل 13 ٪ و 29 ٪ على التوالي بالدولار. في المجمل، كان لدى 2 ٪ من وزارة الطاقة و 9 ٪ من باك لحية. أشارت مستويات التباين في الصفات التي تم مسحها في المقاطعات الثلاث إلى أن WADGs في المنطقة هي في الغالب سوداء، وليست مغمورة، وليست ملتحية ومقرونة.Translated Description (English)

Each class of livestock has some peculiar qualitative traits and in goats some of these are coat pigmentation, horned/polled, beard/non-beard, wattled/non-wattled. Étant donné que l'impact de l'environnement est important dans l'expression phénotypique des traits qualitatifs, il s'accélère pour examiner ces caractéristiques dans les chèvres de la mer d'Afrique de l'Ouest (WADG) de toute région climatique du monde. To accomplish this, a total of 623 WADGs aged between 3 and 4 years reared extensively in Ekiti state region of Nigeria were purposively selected from the three agricultural zones in the state for the examination.

Dans tous les cas, 2 % du bétail et 9 % des barbiches buck had.
