Gene expression pattern and molecular mechanisms involved in Shal and Sangsari sheep fertility using RNA-Seq.

Ovulation rate and litter size are the main reproductive traits with high economic value in the sheep breeding industry. In this study, three Shal ewes (multiparous) and three Sangsari ewes (uniparous) at the age of 5 were used. The live weight was between 45 and 50 kg at an extremely body condition score of 3.
