Variation and frequency of supernumerary teats, litter size, histological features and the fibroblast growth factor 2 (FGF-2) gene expression pattern in goats.

Theriogenology 2022 Feb 26;179:141-148. Epub 2021 Nov 26.

Department of Animal Science, Isfahan (Khorasgan) Branch, Islamic Azad University, Isfahan, 81595-158, Iran.

Historically, female domestic goats carrying multiple kids are mostly unable to express sufficient nursing ability due to a limited number of functional teats. Therefore, the functional teat is an important component in prolific goat breeding, and plays a key role in the future health of their kids. With this motivation, we wanted to investigate the phenotypic features, litter size, histology of adult female mammary glands, and the gene expression profile of the fibroblast growth factor 2 (FGF-2) gene in goats.
