Animal reproductive biology

Edited by: Professor Fuller Bazer
for Journal of Animal Science and Biotechnology

Regarding animal agriculture, reproductive efficiency is a major limitation in many cases to economic success of the livestock enterprise. In this Special Issue devoted to reproductive biology, the papers present results from very basic discovery research that advances understanding of cross-talk between the uterus and conceptus in swine and ruminants and rodents to translational research and technological advances that enhance efficiencies and success of strategies for reproductive management of breeding programs. The findings represent contributions of research with livestock species that are relevant to both animal agriculture and to the biomedical community as small human babies tend to suffer from adult onset of metabolic diseases.

  1. Inadequate delivery of nutrients results in intrauterine growth restriction (IUGR), which is a leading cause of neonatal morbidity and mortality in livestock. In ruminants, inadequate nutrition during pregnanc...

  2. Osteopontin (OPN; also known as Secreted Phosphoprotein 1, SPP1) is a secreted extra-cellular matrix (ECM) protein that binds to a variety of cell surface integrins to stimulate cell-cell and cell-ECM adhesion...

  3. Litter size and birth weights are limited by uterine capacity, defined as the ability of the uterus to maintain the appropriate development of some number of conceptuses. Uterine capacity is the result of the ...
