Bone morphogenetic proteins (BMPs) and the growth factors (GDFs) play an important role in ovarian folliculogenesis and essential regulator of processes of numerous granulosa cells. BMP15 gene variations linked to various ovarian phenotypic consequences subject to the species, from infertility to improved prolificacy in sheep, primary ovarian insufficiency in women or associated with minor subf...
The average twin lambing rate of Bayanbulak sheep is 2% to 3%. However, a flock of sheep with a close genetic relationship and an average of 2 to 3 lambs per birth has been found recently. To determine the major genes controlling the prolificacy of the flock in the present study, the flock was designated A while 100 normal Bayanbulak sheep were randomly selected to comprise the control flock B....
Abstract The objective of this work was to evaluate the effect interaction between feeding level (FL) and body condition score (BCS) on reproductive parameters Pelibuey hair sheep (Ovis aries). experimental units (64 ewes) were randomly assigned one four treatments: low score; high score. significant pregnancy lambing rates. ovulation, estrus returning, pregnancy, prolificacy BCS FL lambing, fu...
The purpose of this study was to assess the ovulatory response and embryo production after repeated superovulation of selected high-prolificacy Rasa Aragonesa ewes at the end of their reproductive life. A total of 211 superovulatory treatments were performed during the breeding seasons of 3 consecutive years. Ewes were given the same gonadotrophin treatment up to three times at intervals of at ...
Small Tail Han sheep is a widely bred farm animal in China which has attracted lots of attention due to their high prolificacy and year-round estrus. However, the molecular mechanism of its fecundity remains unrevealed. The FecB gene polymorphism has been found to be associated with the ovulation rate and litter size of sheep. In the present study, we constructed an iTRAQ-based quantitative pro...
