The Relationship

Genetic diversity and the relationship between genetic distance and geographical distance in red jungle fowl and 14 Chinese indigenous chicken breeds were evaluated using 29 microsatellite loci. The number of alleles per locus ranged from 2 to 25 and the average expected heterozygosity and PIC of all loci were 0.6683 and 0.50, respectively. The average number of alleles per locus ranged from 3.41 in Gushi chicken breed to 6.28 in Wannan Three-yellow chicken breed. The overall expected heterozygosity of 15 Chinese chicken breeds was 0.6686 ± 0.0254 and all breeds showed relatively large heterozygosity. The average of genetic differentiation among populations was 16.4% (<I>P</I> < 0.001). Red jungle fowl and Gushi chicken had distant genetic relationship from other breeds, while Huainan Partridge and Tibetan chicken were more closely related with other breeds. The results did not provide enough support for a significant correlation between the genetic and geographical pair-wise distances.

Males And Females

The anatomical structure of phonation in the domestic chicken Gallus gallus (red jungle fowl, forma domestica) of both sexes was studied to determine sex variations in structures. Ten (10) birds, involving 5 males and 5 females were obtained from a local market for student demonstrations and used for this study. Tracheal rings were observed to be made of circular cartilages numbering thirty and above with the distal most (1/5) tracheal rings narrowed, calcified and fused as the tympanum making part of the Syrinx. The rings become calcified and somewhat collapsed through the bronchial bifurcations. When squeezed, the trachea collapsed completely between fingers but could at releasing the fingers be raised up due to elastic components separating the rings from one another. Other structures involved in vocalization includes straps of muscles. Male structures involved in respiration and vocalization were well formed compared to those of the female. Both tracheobronchialis lateralis and ventralis muscles were thicker than those of the female. Male tracheobronchialis ventralis and dorsalis muscles were well formed and spindle shaped. However, the female tracheobronchialis muscles were seen to be wider compared to the male. The vocal organs (voice box) were seen to be arbitrarily triangular in structure at the bifurcation of the trachea in both sexes. The male Syringeal walls were thinner and were seen to have marked inter Pessula space. The Pessulus mark an abrupt change from the circular trachea to strongly elliptical entrances to the bronchi. It was concluded that the differences in the thinness of syringeal walls coupled with differences between the males and females in other tracheal muscles might be responsible for the stronger vocalization in the male.

Chicken Breeds

The genomic variability of local Italian chicken breeds, which were monitored under a conservation plan, was studied using single nucleotide polymorphisms (SNPs) to understand their genetic diversity and population structure. A total of 582 samples from 23 local breeds and four commercial stocks were genotyped using the Affymetrix 600 K Chicken SNP Array. In general, the levels of genetic diversity, investigated through different approaches, were lowest in the local chicken breeds compared to those in the commercial stocks. The level of genomic inbreeding, based on runs of homozygosity (FROH), was markedly different among the breeds and ranged from 0.121 (Valdarnese) to 0.607 (Siciliana). In all breeds, short runs of homozygosity (ROH) (<4 Mb in length) were more frequent than long segments. The patterns of genetic differentiation, model-based clustering, and neighbor networks showed that most breeds formed non-overlapping clusters and were clearly separate populations, which indicated the presence of gene flow, especially among breeds that originated from the same geographical area. Four genomic regions were identified as hotspots of autozygosity (islands) among the breeds, where the candidate genes are involved in morphological traits, such as body weight and feed conversion ratio. We conclude that the investigated breeds have conserved authentic genetic patterns, and these results can improve conservation strategies; moreover, the conservation of local breeds may play an important role in the local economy as a source of high-quality products for consumers.
