Morphometric characterization of Pirot pramenka
Biotehnologija u stocarstvu(2021)
Abstract
The strategy of conservation of endangered sheep populations implies
morphological and genetic characterization, as basic preconditions for their
conservation. The aim of this study was to determine the morphometric
characteristics, their correlations and the index of physical development of
Pirot pramenka, which has the status of the most endangered population in
Serbia. The measuring was performed on 30 sheep, aged 3 years, reared in the
area of Stara Planina. The descriptive statistical procedure was performed
using the statistical package Statistica (version 8). The average height at
the withers was 56.31 cm, body length 62.93 cm, chest width 18.37 cm, chest
depth 25.96 cm, chest circumference 77.59 cm, shin circumference 6.70 cm.
The strongest and significantly positive correlation (P <0.05) was found
between chest depth and height at withers (0.65), body length (0.58) and
body weight (0.56). Pirotska pramenka has slightly higher indices of format,
chest and massiveness, in relation to breeds Vitoroga Zuja and Travnik
Pramenka. These morphometric traits suggest that, compared to previous
research, the body frame of Pirot pramenka sheep did not change
significantly, which means that there were no crosses with other breeds due
to geographical isolation and enthusiasm of breeders to preserve the
indigenous Pirot pramenka which was the starting point for following
authentic brands: Pirot lamb, cheese and carpet. Hence the biological and
moral imperative: to preserve this highly endangered population.
