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

Good detection of estrus is critically important in dairy husbandry. Incorrect detection of
estrus is related to loss of profit due to extended calving intervals, milk loss, veterinary costs …

Dairy cows are especially vulnerable to health disorders during the transition period, when
they shift from late pregnancy to the onset of lactation. Diseases at this stage affect not only …

The cause of low fertility in dairy cows is multifactorial. Poor nutrition during the dry and early
postpartum periods results in reduced glucose, insulin, insulin-like growth factor (IGF-I) and …

Contents There is evidence that the reproductive performance of dairy cows has declined as
milk yields have increased over the last 40 years. Identifying the precise cause (s) of this …

There is much debate about possible antagonism between high milk production and
reproductive performance. This paper reviews methods of measuring reproductive …

After 80 years of the commercial application of artificial insemination (AI) in the cow, the
method still has numerous benefits over natural insemination including worldwide gene …

The primary objective of this randomized controlled experiment was to evaluate the
insemination dynamic and reproductive performance of cows managed with a targeted …

A general belief across the dairy community, both scientific and commercial, is that of an
antagonistic association between milk production and reproductive performance of dairy …

Infertility has been often correlated to a rising milk yield in high producing dairy cattle. The
aim of the present study was to evaluate, using logistic regression procedures, the effects of …
