Editorial
Demand of equines throughout the world has decreased during the last few decades mainly due to their lesser work utility. In India also, population of horse and pony breeds has also decreased continuously from 1.50 million to 6.10 million during the last five decade (Livestock Census 2007) which has placed all the four registered pony breeds, namely Zanskari, Spiti, Manipuri and Bhutia into endangered breed category [1]. Animals of each breed are available in small number in different pockets throughout their home tracts. Manipuri pony is believed to be the oldest pony breed in world to be used as “Polo Pony” and at present, its total population in its home tract is around 400 to 1218 only. Exact population of true to breed animals of this breed is not yet clear due to lack of proper breed recording system. Same is the fate of other pony breeds namely Zanskari, Bhutia and Spiti In their home tracts. These pony breeds have acquired some unique characteristics which have enabled them to adopt themselves in the harsh climate and difficult terrains in their home tracts. These ponies are known for their sturdiness, stamina, speed on hilly and difficult terrains, high disease resistance, surefooted animals, and used mainly for riding and as pack animals in cold hilly regions. Zanskari pony is considered the hardiest amongst all the pony breeds and can work in the extremes of altitude and temperature. In view of their unique characteristics, it is an important issue for conservation biologists to conserve these breeds as future requirements of these breeds is not known.
It is well established that populations that have reduced in their demographic sizes, commonly show decreased genetic diversity among them [2-6]. Maintenance of adequate genetic diversity among animals of individual breed or species is quite important for the existence of that breed or species. Further continuous decline in populations can lead to demographic bottlenecks which may promote inbreeding depression [7,8] and hinder a population’s ability to adapt to environmental charges [9,10]. All such conditions are expected to increase a population’s risk of extinction [11,12].
Demographically all the four Indian pony breeds has decreased appreciably but high genetic diversity in terms of allelic richness and heterozygosity, has been observed in them [13-16] which is contrary to the common observations [2-8]. Maintenance of high genetic diversity in these pony breeds could possibly be either due to segregation of small animal clusters of individual breed in different pockets in their home tracts or due to selective breeding strategies adopted by local breeders in the recent past [17,18]. Though Spiti and Zanskari resemble closely to each other but animals of both the breeds have high genetic diversity among them also [16] which seems to be good enough for adapting suitable breeding policies for conservation of all the endangered pony breeds. Question of maintaining this genetic diversity in future is also quite important as further decline in overall population of each breed can lead to complete loss of these breeds. It is pertinent that if timely suitable conservation strategies are not implemented than these breeds may become an extinct breeds in near future.
