Goat ovary

Molecular regulation of the hypothalamic-pituitary-gonadal (HPG) axis plays an essential role in the fine tuning of seasonal estrus in Capra hircus. Noncoding RNAs (ncRNAs) are emerging as key regulators in sexual development and mammalian reproduction. In order to identify ncRNAs and to assess their expression patterns, along the HPG axis, we sequenced ncRNA libraries from hypothalamus, pituitary and ovary of three goats.

The goat is an important farm animal. Reproduction is an important process of goat farming. The ovary is the most important reproductive organ for goats. In recent years, an increasing number of long non-coding RNAs (lncRNAs) have been implicated in the regulation of mammal reproduction.

The present study was to determine the expression of proliferating cell nuclear antigen protein (PCNA) in the sheep and goat ovaries. The localization of PCNA was demonstrated in 5µm thick formalin fixed, paraffin embedded tissue sections of sheep and goat ovarian tissue using primary mouse monoclonal anti-PCNA antibody. Staining for PCNA was not observed in pregranulosa cells but observed in the oocytes of primordial follicles. In primary to secondary follicles, positive staining in oocytes and in some granulosa cells was detected.

In this study, oocytes were recovered from 200 numbers of goats’ ovaries from different slaughterhouses for subsequent use in-vitro maturation, enucleation, reconstruction and embryo culture to produce cloned embryos. The collected oocytes were classified into three categories (Grade A, B and C) based on their appearance of homogenous granular ooplasm and layers of cumulus cells surrounding oocytes under a stereozoom microscope. The average oocyte recovery, In-vitro maturation and the enucleation rates were found to be 3.36 per ovary, 60.37 per cent and 75.52 per cent respectively.
