Morphometric Performances of Thin Tail Sheep with Differences Calpastatin (Cast-1) Genotipees

Abstract

Calpastatin (CAST) is an indigenous inhibitor of calpain that involved in regulation of protein turn over and growth. The objective of this research was to compare the morfometric performances of thin tail sheep with difference of CAST genotipees. PCR-RFLP method was carried out to identify genetic variation of CAST gene. Based on the identification, variation of CAST gene that found were MM and MN with the single Calpain genotype variation, TT. Nine thin tail sheeps from Jonggol were used for this research. The sheeps clustered based on the variation CAST gene, 5 sheeps were MM genotype and 4 sheeps were MN genotype. Variation of CAST gene gave significantly differences in morfometric performances. Sheeps with MM genotype have longer body length, heart girth, wither depth, and rump width than sheep with MN genotype. Sheeps with MM genotype had longer Ossa vertebrae cervicales Ossa vertebrae thoracicaeOssa vertebrae lumbales, Os vertebrae sacrales and Os scapulae.
