The transition from pregnancy to lactation (ie the transition period) is a time of significant
metabolic challenge, with a several-fold increase in a cow's requirement for energy, protein …

In cattle, the majority of pregnancy loss can be attributed to early embryonic loss which
occurs prior maternal recognition of pregnancy on Day 16 (Day 0= ovulation). During this …

This study sought to determine the earliest response of the bovine uterine endometrium to
the presence of the conceptus at key developmental stages of early pregnancy. There were …

The advent of in vitro fertilization (IVF) in animals and humans implies an extraordinary
change in the environment where the beginning of a new organism takes place. In mammals …

Viviparity (live birth) has evolved more than 150 times in vertebrates, and represents an
