“…Manwell and Baker (1977) suggested that electrophoretic variants with low frequencies may represent, in many cases, relative recent mutations occurring after divergence of the breeds; this could be the case with the Balami breed. Akinyemi and Salako,(2012) also reported Tf P in Balami breed and the same was also reported for SardiandBeni Ashen sheep breeds in Morocco (Boujenane et al, 2008), and it is reported to be more widely distributed in European sheep breeds (Buis and Tucker, 1983;Zanotti et al, 1990).…”

“…Nei (1972) standard genetic distance (D) obtained in this study (0.034-0.640) indicates the level of genetic differentiation between the breeds. Buis and Tucker (1983) reported D values of 0.181 to 0.308 between different sheep breeds and an average D value of 0.248. Different authors have reported different values of D in different sheep breeds.…”

The study used 100 indigenous sheep comprising 25 Balami, 25 Uda, 25 Yankassa and 25 West African Dwarf breeds reared extensively. The blood samples were taken from Vena Jugularis, processed according to standard procedure and transferrin and haemoglobin examined using cellulose acetate electrophoresis. The observed allele frequencies and genotypes (%) were tested with Hardy-Weinberg's Equilibrium (χ 2

“…Many studies in sheep have already linked these markers to production traits and environmental adaptation (Vicovan and Rascu, 1989;Charon et al, 1996;Salakoet al, 2007). Information on blood proteins has also been extensively used for parentage control (Francois et al, 1992) and to study the genetic relationships among sheep breeds (Buis and Tucker, 1983;Ordas and San Primitivo, 1986;Mwacharoet al, 2002). However, the polymorphism of these important blood proteins had not being linked to survivability traits in the populations of sheep of Northern Nigeria (Balami, Uda and Yankasa sheep).…”

Survivability of lambs in relation to their dam’s haemoglobin variants

et al. 2014

A total of 65 Yankasa, 23 Uda and 16 Balami ewes were mated to 4 Yankasa, 3 Uda and 3 Balami rams in a diallel breeding pattern to produce 192 lambs within 9 genotypes, which were used to study survivability of lambs in relation to their dam?s haemoglobin variants. Blood samples (5ml) were collected from 104 ewes and 10 rams through jugular venepuncture. Electrophoresis was carried out in a Shandon electrophoresis tank on cellulose acetate strips. Each of the 9 lamb genotypes had very high proportion of HbAB. The dam?s haemoglobin type BB (HbBB) were only found in YK X YK, UD X UD, YK X UD, BL X YK and BL X UD lambs at birth and 90-Day. Survivability of lamb that were given birth to by dams with haemoglobin type (HbAB) is highest in the studied populations from birth to 360-Day. Lambs with Hbshould be selected for improved survivability of sheep in Northern Nigeria.

The phylogenetic relationships among 23 local sheep breeds and varieties in East Asia were determined based on allele frequency data for five informative and polymorphic blood protein and nonprotein loci (transferrin, arylesterase, hemoglobin-beta, X-protein, and potassium transport) using electrophoresis and ion-densitometric techniques. Comparatively striking differences in the frequency distributions, especially of hemoglobin-beta and X-protein alleles, were seen between the northern population of the Khalkhas, Bhyanglung, Baruwal, Jakar, Sakten, and five Chinese breeds and the southern population of the Bengal, Kagi, Lampuchhre, Myanmar, and Sipsu breeds. Clustering analyses using UPGMA and NJ methods and principal component analysis, using the data of all populations and loci tested, clearly demonstrated the difference. The two population groups are divided by the boundary of the Himalayas, and each diverged into three subgroups: Mongolian, Tibetan, and Himalayan groups in the north and Indian groups I, II, and III in the south. It was noted that the genetic differentiation of populations was more distinct in the northern group. These findings strongly suggest the existence of at least two large and phylogenetically different gene pools of sheep in East Asia.
