Abstract

Abstract: 【Objective】The relation between different BMPRIB genotypes in Small Tail Han sheep and FSH receptor and LH receptor mRNA levels during the oestrum was studied 【Method】Semi-quantitative PCR. 【Result】The results showed that the FSH receptor mRNA levels from the right ovary of BB (1.14±0.11) ewes were higher than those of AA (0.44±0.11) and AB (0.36±0.08) ewes (P<0.01). LH receptor mRNA levels from the right ovary of BB (0.42±0.02) ewes were significantly higher than those of AA (0.23±0.02) and AB (0.25±0.04) ewes (P<0.01), but was no significant difference in the left ovary among the genotypes during the oestrum was observed. 【Conclusion】It is concluded that the higher mRNA levels of FSH and LH receptor may be one of the reasons of fecund Small Tail Han sheep.

Key words: BMPRIB, Small Tail Han sheep, FSHR, LHR, Fecundity
