Effect of once daily milking and concurrent somatotropin on mammary tight junction permeability and yield of cows.
Six pairs of monozygous Friesian twin cows during late lactation were used to assess the effect of once daily milking and bST treatment on yields and tight junction permeability of mammary epithelialExpand

Rumen-protected choline administration to transition cows: effects on milk production and vitamin E status.
We investigated the influence of rumen-protected choline (RPC) supplementation on milk production, lipid metabolism and vitamin E status in dairy cows receiving a silage-based diet. Twenty-sixExpand

Plasmin and plasminogen in bovine milk: a relationship with involution?
A total of 774 individual milk samples were collected from 66 Holstein cows between October 1987 and April 1988. Samples were analyzed for plasmin, plasminogen, and SCC. An increase in SCC from lessExpand

Environmental factors affecting plasmin activity in milk.
A total of 367 milk samples were collected from 43 individual Holstein cows during 1 yr. Samples were analyzed for plasmin activity, total casein, alpha s-casein (alpha s1-casein + alpha s2-casein),Expand

Evaluating multimodal driver displays under varying situational urgency
This paper describes an experiment evaluating all multimodal combinations of such warnings under two contexts of situational urgency to assess their effectiveness both in the presence and absence of critical driving events. Expand

Effects of vitamin E on immune function of dairy cows.
The effect of vitamin E supplementation on the immune function of dairy cows was studied. Twelve cows were assigned to 1 of the 2 experimental groups: control (no vitamin E supplementation), andExpand

Effect of milking frequency and somatotropin on the activity of plasminogen activator, plasminogen, and plasmin in bovine milk.
Six pairs of identical twin cows during late lactation (213 d) were used to study the effect of milking frequency (twice vs. once daily) and bST during once daily milking on the activity ofExpand
