“…In conclusion, the application of discriminate analysis to morphometric variables in dogs belonging to several Podenco breeds enabled breeds and varieties to be clearly distinguished, as reported for other species Capote et al;Crepaldi et al;Macciotta et al;Rodero et al;Lanari et al;Zaitoun et al;Luque et al;Dossa et al;Marrube et al;Vargas et al;Traoré et al, 2008a;Traoré et al, 2008b).…”

“…The method used here has been applied to goat breeds (Herrera et al, 1996). In general terms, the examination of morphometric variables using discriminate analysis techniques (simple, stepwise, cluster and canonical) has enabled the differentiation of breeds and varieties of various domestic species Capote et al, 1998;Crepaldi et al;2001;Macciotta et al, 2002;Rodero et al, 2003;Lanari et al, 2003;Zaitoun et al, 2005;Luque et al, 2005;Dossa et al, 2007;Marrube et al, 2007;Vargas et al, 2007;Traoré et al, 2008a;Traoré et al, 2008b).…”

SUMMARY:The term Podencos refers to a group of dog breeds from Spain and classification in Group 5 of dog breeds by the Fédération Cynologique Internationale (FCI). The aim of this study was to compare traits morphometric breeds of Podencos; Canario, Ibecenco, Andaluz (small, medium and large) and Orito. Ten morphometric variables were measured in 385 animals (245 females and 140 males), head length, muzzle length, height at withers, rump height, body length, head width, rump width, chest depth, chest girth and the shin circumference. Morphostructural variables were more homogeneous in the Podenco Ibicenco and the Podengo Canario, because for many years there were gradually distinctive trait standards for each breed. The discriminate analysis indicated morphostructural differences between all breeds, as reflected in the significant Mahalanobis distance, and confirmed that the hound Orito may be accepted as a different dog population.

“…For example, the most common native breed in the Kingdom of Saudi Arabia (KSA) is the Ardi goat (Alamer, 2006), which is historically assigned to Arabian deserts and is a plausible descendant of the Hejaz goat (Epstein, 1946). A similarly looking breed is the most common goat breed in Jordan, which is the Black Bedouin (Al-Tamimi, 2005), also known as Dihawi (Zaitoun et al, 2005). On the other hand, the most known goat breed in Syria is the Damascus goat, known sometimes as Shami.…”

ABSTRACT.The present study aimed to analyze genetic relatedness and differentiation of common native goat populations in some countries of the Middle East. The populations were Ardi, Black Bedouin, and Damascus goats in the Kingdom of Saudi Arabia, Jordan, and Syria, respectively. Domesticated goats of the Middle East are mostly related to common ancestors, but there is limited molecular genetic evidence. Four microsatellite DNA markers were genotyped in 89 individuals of the three populations using an automated genetic analyzer. Ardi, Black Bedouin, and Damascus goats exhibited high average allele number and expected heterozygosity of 8.25, 9, and 7.25, and 0.750, 0.804, and 0.779, respectively. F-statistics for population differentiation showed 6.0% of total genetic variation, whereas 94.0% as differentiation between individuals within all populations. The least varied within populations was Ardi goats, then Damascus goats and finally Black Bedouin goats. Furthermore, the Damascus goat population was more differentiated from Black Bedouin goats than from Ardi goats. On the other hand, there was strong evidence of admixture between the majority of Ardi and Black Bedouin goat individuals but little with those of Damascus Goat genetic relatedness and phylogeny goats. Genetic distance between Ardi and Black Bedouin goats was the shortest, whereas it was the longest between Ardi and Damascus goats. The phylogenetic tree clearly revealed the expected degree of differentiation in the three populations. From a genetic conservation point of view, it is recommended to maintain the biodiversity of these distinct populations in case genetic migration of genetic resources and genetic conservation are absent.

“…In Nigeria, morphometric differentiation of indigenous small ruminant populations has been restricted to the use of analysis of variance (Fajemilehin & Salako, 2008). However, such type of analysis has limited power and multifactorial analyses of morphological traits are more appropriate to assess phenotypic variation within and between goat populations; and to appropriately discriminate different goat types because of the joint consideration of all measured morphological variables (Lanari et al, 2003;Zaitoun et al, 2005;Dossa et al, 2007;Traore et al, 2008). This becomes imperative because uncontrolled mating and geographical overlap are leading to the endangerment of breed purity and potentially important reservoir of caprine genetic resources is being put at risk.…”

This study evaluated the usefulness of morphological characteristics to distinguish two important indigenous goat breeds in Nigeria. Fifteen morphometric traits were measured on West African Dwarf -WAD (n = 160) and Red Sokoto -RS (n = 142) goats that ranged in age of up to 19 months and were reared extensively in villages in southern and northern Nigeria. Univariate analysis revealed that the body measures of RS goats were significantly higher than those of WAD goats. Canonical discriminant analysis gave better resolution, as only seven external morphological characteristics of strong discriminating power were extracted. The most discriminant variable between the two goat populations was rump height, followed in order by body length, horn length, face length, chest girth, neck circumference and head width. The discriminant function obtained correctly classified 100% of individuals from the sample of known goat populations. The classification accuracy of the function was cross-validated using the split-sample method, and indicated a 99.7% success rate (99.4% of WAD goats and 100% of RS goats were correctly assigned to their source genetic group). This study indicates that a discriminant tool may be used successfully in the field to separate WAD and RS goats. The present results could be complemented by molecular characterization using DNA markers for better management and conservation strategies of genetic resources for indigenous goats.
