The biological cycles of milk production and reproduction determine dairying profitability
thus making management decisions dynamic and time-dependent. Diseases also negatively …

Fertility in dairy cows has declined over the past five decades as milk production per cow
has increased. Many hypotheses have been proposed to explain this including issues of …

Data derived principally from peripheral tissues (fat, muscle and liver) show that insulin
signals via diverse interconnecting intracellular pathways and that some of the major …

The paper presents an update of our 1993 model of ovarian follicular development in
ruminants, based on knowledge gained from the past 15 years of research. The model …

For heifers, beef and moderate-yielding dairy cows, fertilisation generally exceeds 90%. In
high-producing dairy cows, it may be lower and possibly more variable. The major …

For heifers, beef and moderate-yielding dairy cows, it appears that the fertilisation rate
generally lies between 90% and 100%. For high-producing dairy cows, there is a less …

The establishment and maintenance of pregnancy in lactating dairy cows is a complex
biological event that is influenced by a multitude of factors, from the reproductive biology of …

The 6 to 8-week period centered on parturition, known as the transition or periparturient
period, is critical to welfare and profitability of individual cows. Fertility of high-producing …

STUDY QUESTION Is the metabolic composition of the follicular fluid of women undergoing
assisted reproductive treatment (ART) related to serum composition and BMI and is it …

In pasture-based dairy systems, supplementary feeds are used to increase dry matter intake
and milk production. Historically, supplementation involved the provision of the same …
