Attainment of puberty is a key developmental event influenced by genetic and environmental factors. In examining age at attainment puberty, we observed closely related rams from the Davisdale line whose daughters differed in which they attained puberty. A candidate gene approach was used to identify mutations that may underlie these differences. Four with divergent phenotypes for their daughter's onset were selected whole-genome sequencing. The coding regions genes known roles regulating...

Buffalo, the premier dairy animal in India, suffers from slow growth rate, delayed puberty, and silent heat. It is not known whether delay puberty such animals due to expression of hypothalamus-pituitary-gonadal functions.

The Anti-Müllerian Hormone (AMH) is a member of the transforming growth factor beta (TGF-β) superfamily, playing significant role in cell proliferation, differentiation and apoptosis. In females, AMH secreted throughout their reproductive life span from ovaries, whereas males it by gonadal cells at very early stage testicular development. promising marker ovarian reserve women can be used to measure female lifespan. present study, we cloned sequenced GC rich gene Indian riverine buffalo (...

Summary Previous studies have suggested that growth‐hormone‐releasing factor (GRF) enhanced growth and advanced puberty onset along with hormonal changes in buffalo heifers ( Bubalus bubalis ). However, it is not known to what extent exogenous GRF could influence blood metabolites minerals bring about heifers. Therefore, we planned investigate the effect of bovine (bGRF) on during a 3‐month pre‐treatment period, 9‐month treatment period 1‐month post‐treatment period. Six were treated...
