characteristics of balami sheep

Phenotypic characterization of animal genetic resources. The basic descriptive statistics of the morphological traits of WAD, Yankasa, Uda and Balami sheep are presented in Table 1.The biometric traits of Uda and Balami sheep were significantly (p < 0.05) higher than those of WAD and Yankasa, although the latter had superior mean values than the former for all morphometric traits with the exception of EL. Le tableau 2 présente la répartition par sexe et par tranches d’âge de l’échantillon d’étude selon l’échelle de dentition (Hamito, 2009). The Balami is fast growing and attains a weaning weight of 18 kg in 12 weeks. Flocks include multiple females, offspring, and one or more males. Matured males have dewlap Balami is a fast growing animal with a good potential for milk production. AJOL is a non-profit, relying on your support. Selon Hall (1991), les animaux d’origine tropicale sont de grande taille et ne sont longs. Res., 80: 62–67. Philos. Du même auteur, le Balami aurait une origine occidentale que tropicale. Productivity of ewes estimated as weight of weaned lamb per annum or as weight of weaned lamb per kg metabolic weight of ewe per annum increased with the age of ewe to about 55 months of age. Discriminant analysis of morphometric differentiation in the West African Dwarf and Red Sokoto goats. Cependant, pour mieux apprécier ses performances zootechniques, il est important de connaître ses caractéristiques phénotypiques. Multivariate analysis of morphostructural characteristics in Nigerian indigenous sheep, Ital. Institut National de la statistique (INS) (2018). Characterization and conservation of genetic diversity in subdivided populations. En effet, ces auteurs ont trouvé parmi les variables les plus discriminantes la largeur de la tête, la circonférence à la base de queue et la circonférence du museau. In Small Ruminant Research and Development in Africa. Table II. La différence d’effectifs entre les mâles et les femelles peut être à la base de cette situation. While 41.22% of Uda sheep were misclassified as Yankasa sheep, 35.35% of Yankasa were wrongly assigned as Uda sheep, showing the level of genetic exchange that has taken place between the two breeds overtime. Yakubu A., Ibrahim I.A. L’analyse en composantes principales a fait ressortir des corrélations fortes des variables en différents groupes. The quality of rams of local breeds is an important instrument to promote the consumption of meat in the local population [3]. Créé par: Baptiste Morvan. Type of birth, age of dam and sex had significant effects on weights at all ages. La méthodologie a consisté d’abord à faire un recensement des éleveurs, suivi d’un entretien avec ces derniers afin de recueillir leur adhésion. The traits were subjected to principal component (PC) analysis to reduce data dimensionality. Cette figure permet en outre de constater que l’axe 1 est caractérisée par les paramètres HG, HC, TP, P, Lsi, LT, LC, lp, LQ, CBQ, cm, Lb et Lc, le second axe est plutôt caractérisé par LO, lo et lt. En outre, cette figure permet de lire que globalement, tous les paramètres sont en corrélation positive avec le sexe mâle et négative avec le sexe femelle. Hizkel K, Yoseph M, … One of their unique characteristics is that all of the above mentioned sheep breeds are hairy types. The entire locus was found to be polymorphic. Management systems. Similar … En considérant comme variables dépendantes la commune et le sexe et comme variables explicatives les 17 paramètres morpho-biométriques quantitatifs, les deux premiers axes factoriels de l’AFD expliquent 85,8% de la variabilité (Figure 3). Sadly, I talk with people sometimes who say, “I’ve lost my way,” or “I just feel dead inside,” or other similar phrasing. Le Niger est un pays d’élevage par excellence. It targeted the area of choice of the breed including the Regions of Maradi (Azagor, Bermo, Dakoro communes) and Tahoua (Madaoua commune). The age, body weight, scrotal circumference and spermiogram of the rams were studied by standard techniques. The males (rams) have horns while the ewes (female sheep) have no horns. Chez les ovins, où l’embouche ovine est l’un des premiers objectifs des éleveurs, les mâles sont donc prioritairement orientés vers cette spéculation, ce qui diminue leur nombre au sein du troupeau (Traoré et al., 2006). Mean birth weight was 3.3kg and weights at 4 and 10 weeks of age were 7.4 and 12.1kg respectively. Cette différence est d’autant significative au-delà de trois mois. 10, No. Nearest neigh-bour discriminant analysis showed that most Balami sheep (61.45%) were classified into their source genetic group. The Merino sheep and its crossbreeds are the basis of southern hemisphere fine wool production. Technical Bulletin, 23: 11. They are very famous for hair production. Pour cela, et du fait que l’essentiel des variables principales mais aussi supplémentaires ont leurs cosinus carrés élevés sur ces axes, le premier plan factoriel (F1xF2) s’adapte bien pour l’interprétation des résultats de l’analyse. Les ovins représentent 29,6% du cheptel (Niger, 2007) et représentent numériquement la seconde espèce élevée au Niger (Niger, 2014).
