“…An investigation using microsatellite markers reported the three groups of Egyptian chickens (Eltanany et al, 2011). Ramadan et al (2011) compared the phylogenetic differentiation between two Egyptian chicken breeds with mtDNA D-loop region. However, there are few works to evaluate the genetic diversity on Egyptian native chickens using mtDNA sequences.…”

This study was aimed to evaluate the genetic diversity of Egyptian native chickens by using mtDNA sequence polymorphism. A 546-bp fragment of the mtDNA D-loop region was sequenced for a total of 36 Egyptian native chickens with 14 reference sequences from DNA databank. Of the Egyptian chickens 5 haplotypes were identified. Haplotype diversity and nucleotide diversity of the Egyptian native chickens were 0.5635±0.0845 and 0.00123± 0.00108, respectively. The Egyptian native chickens were distributed within one clade, which were closed to the haplotypes from Indian subcontinent and Southeast Asia. Most of Egyptian native chickens were classified into the haplotype E1, which contains 63.9% of individuals followed by E4 (16.6%), E5 (11.1%), E2 (5.5%) and E3 (2.7%), respectively. These findings indicate that the maternal lineages was involved in the origin of domestic chicken in Egypt may have roots in Indian subcontinent and other Southeast Asia. The genetic information from this study will probably pave the way to further studies for evaluation, preservation and improvement of Egyptian native chickens as genetic resources in the future.

“…Since the D-loop region evolves much faster than other regions of the mtDNA genome, it is the most valuable and sensitive region that is suited to genetic variation studies within species (Niu et al, 2002). The efficiency of mtDNA D-loop in genetic variation assessment has been reported with White Leghorn, Plymouth Rock, and Rhode Island Red chickens in Japan (Harumi et al, 2004), Korean chickens (Lee et al, 2007), Japanese native chickens (Oka et al, 2007), and Egyptian local chickens (Ramadan et al, 2011). The aim of this research is to investigate the potential genetic diversity in the newly characterized Saudi chicken lines Hajar1 and Hajar2 and other exotic Indian, Chinese, Japanese, Mediterranean and commercial chicken populations, using a mtDNA marker-based technique, and to construct a phylogenetic tree with them.…”

“…mtDNA has been used intensively because it has proved suitable for phylogenetic comparisons within and among closely related species (Avise & Zink, 1988). The mtDNA polymorphism has largely been applied for understanding genetic relationships in chickens ( Lee et al, 2007;Ramadan et al, 2011;Bondoc, 2013) and other avian species (Patel et al, 2010;Kerr, 2011).…”

This study was conducted to assess genetic diversity of Hajar1 and Hajar2 local Saudi chicken lines using mitochondrial DNA (mtDNA) D-loop partial sequences. One hundred blood samples were obtained equally from Hajar1 and Hajar2 Saudi chicken lines as 50 samples from each line. The D-loop region was partially amplified from genomic DNA with a conserved primer set, and the fragments were sequenced. Eight published reference mtDNA sequence data from the GenBank were used for comparisons, and multiple alignments were performed. The most common haplotype was assigned as a basic sequence for comparing within each line. Entropy plot and conserved region analysis were performed. Genetic distances and neighbour-joining (NJ) phylogenetic trees were estimated. The results indicated haplotype variations within and between local Saudi chicken lines, which could explain the phenotypic variation reported earlier. A close genetic relationship was shown between the Saudi local chicken lines. Unique conserved regions and nucleotide substitutions were observed between the two lines. Both lines have a close relationship with the reference Asian local chicken population, especially local Chinese and Indian chicken breeds. The current results are considered the first report of mtDNA sequence diversity for Hajar1 and Hajar2 lines. Further detailed molecular genetic studies of both lines are indispensable to genetic conservation and development. ______________________________________________________________________________________

“…Indigenous chickens have desirable traits such as disease resistance, pleasantly flavoured meat and eggs, and the ability to withstand adverse environmental conditions (Ramadan et al, 2011;Padhi, 2016). Crossing indigenous strains with exotic commercial ones could take advantage of high egg production in the exotic strain and the adaptation of the indigenous strain to the Egyptian environment.…”

A crossbreeding experiment was conducted between the Sinai (SI), an indigenous Egyptian strain, and the exotic Lohmann Brown (LB) breeds of chickens. A total of 790 chicks were produced in four genetic groups, namely SI x SI, LB x LB, SI x LB, and LB x SI. The objective was to estimate the direct additive effect (gi), individual heterosis (hi), and maternal additive effect (gm) for growth and reproduction traits. Direct additive effects were positive (P ≤0.01) for bodyweight (BW) at 4, 8, and 12 weeks old in favour of SI. For egg production traits, gi was positive for age at sexual maturity (ASM) and age at which the first 10 eggs were produced (P10), but negative for mean 10 egg production (MP10), egg number at 90 days (EN90),mean egg number at 90 days (MEN90), and egg mass (EM). The estimates of heterosis (%) were high for BW and daily gain except for BW0. Maternal effect estimates of BW and daily weight gain were significant (P <0.05) only for bodyweight at hatching (BW0), bodyweight at 4 weeks old (BW4) and daily weight gain from four to eight weeks old (DWG4-8). Thus, the Sinai and Lohmann Brown crossbreed produced favourable heterosis on the growth of the chicks. As an adapted indigenous strain, SI should be regarded as a dam line in crossing with LB, which has greater genetic potential for growth. Use of LB as a sire strain in conjunction with Sinai would increase egg production from the resulting hybrid chickens.
