Gut Microbiota Concerning Reproductive Health of Domestic Animals

Anoop Kumar, Ashutosh Mishra, Pratyanshu Srivastava, Amrita Priyadershi, Ajoy Ghosh & Anupam Soni · Journal of Advances in Biology & Biotechnology · 2025

The animal gut microbiota made up of trillions of gastrointestinal tract microorganisms functions as a crucial part of metabolic processes as well as immunity and reproductive health. The microbiome–gut–reproductive axis (MGRA) demonstrates how gut microbial patterns regulate rep...

High-Rise Syndrome Associated Stillbirth and Obstructive Dystocia in a Pregnant Rhesus Macaque (Macaca mulatta)

Adhithya Muththuswamy J., Uttam Kumar Sahu, Brijesh Kumar, Pratyanshu Srivastava, Anurag Patel, Mahima Porwal, Vishnu Vadera, Mayank Singh, A. M. Pawde, Vandana & Narayanan Krishnaswamy · Journal of Scientific Research and Reports · 2026

Stillbirth in non-human primates represents failure of the maternal–fetal–placental unit and may result from abnormal fetal presentation, maternal compromise, or trauma. In rhesus macaques, mean gestation length is approximately 166 ± 3 days, and normal neonatal birth weight rang...

Comparative Study of Estradiol-Supported In-vitro Maturation in Hariana and Sahiwal Oocytes under Weekly and Bi-Weekly Protocols

Anoop Kumar, Atul Saxena, Mukul Anand, Ashutosh Mishra, Amrita Priyadershi & Pratyanshu Srivastava · Journal of Advances in Biology & Biotechnology · 2025

Estradiol is a key hormone that helps in the development and growth of bovineoocytes, playing an important role in in-vitro maturation (IVM) outcomes for cattle. This study evaluated the effects of estradiol supplementation at concentrations of 0.5 μg/mL, 1.0 μg/mL, and 1.5 μg/mL...
