There is considerable evidence to indicate the existence of local control of mammary gland involution, but the exact nature of this control has yet to be defined. Stanniocalcin-1 (STC-1) is a newly discovered mammalian hormone that seems involved in

Stanniocalcin-1 is a hormone that possesses both paracrine and endocrine functions and has recently been identified in mammals. While paracrine functions have been determined for several organs, the role of circulating stanniocalcin-1 in cattle is st

Increasing amounts of estrogens in the blood of pregnant lactating cows may be one factor inducing the progressive involution of the mammary gland after the peak of lactation. The present study was undertaken to assess the effects of 17β-estradiol o

Thirty Holstein cows in mid-lactation (158±20 DIM) were given a total mixed ration based on grass silage, maize silage and rolled barley. After a preliminary period of 1 week, this diet was supplemented with nothing (control), unprotected fish oil (

Milk production is a function of the number and activity of mammary epithelial cells, regardless of stage of lactation. Milk yield is generally higher in multiparous cows than in primiparous cows, but persistency is usually greater in the latter grou

The decline in milk yield observed after peak production in dairy animals results from apoptotic death of mammary epithelial cells. In cows, this decrease in milk yield can be accelerated by injection of 17beta-estradiol, thus evoking a possible role

Six midlactation Holstein cows were fed a total mixed ration supplemented with either 4.8% canola meal, 3.3% unprotected canola seeds plus 1.5% canola meal, or 4.8% formaldehyde-protected canola seeds, according to a double 3 × 3 Latin square design
