Abstract
The study presents the genetic diversity of Katchaikatty Black, an endangered and culturally significant sheep breed of Tamil Nadu. A panel of 25 microsatellite markers recommended for Indian sheep was used for genotyping. Considerable genetic variation in terms of allele diversity and heterozygosity was observed within the investigated breed. A total of 174 distinct alleles were detected across the analyzed microsatellite loci with an average of 6.96 alleles per locus. The average observed and expected heterozygosity values were 0.600 and 0.706, respectively. The positive heterozygote deficiency (FIS) value of 0.171, estimated for this breed may be due to the possibility of Wahlund effect resulting from sampling from different breeding flocks, i.e. different villages and flocks in the same area. A normal L-shaped curve suggested absence of genetic bottleneck in this breed. The information generated will be useful in guiding conservation and management programmes for Katchaikatty Black sheep.
期刊介绍:
Articles published in The Indian Journal of Animal Sciences encompass a broad range of research topics in animal health and production related to cattle, buffalo, sheep, goat, camel, equines, pig, rabbit, yak, mithun, poultry and fisheries. Studies involving wildlife species and laboratory animal species that address fundamental questions about their biology will also be considered for publication. All manuscripts must present some new development and must be original, timely, significant and scientifically excellent. Papers will be rejected if standards of care of, or procedures performed on animals are not up to those expected of humane veterinary scientists. At a minimum, standards must meet the International Guiding Principles for Biomedical Research involving Animals, as issued by the Council for International Organizations of Medical Sciences. (C.I.O.M.S., c/o WHO, CH 1211 Geneva 27, Switzerland). Articles reporting new animal disease must follow GOI directive as given in detail in Guidelines to Authors.
