The effects of varying densities of lone star tick, Amblyomma americanurn (L.), on measured physiological parameters of beef cattle in a controlled environment was determined. Steers were infested with either 0, 20, 60, or 120 pairs of adult ticks. H

Cattle grazing in the presence of low-level infestations of stable flies (Stomoxys calcitrans L.) may offset reductions of grazing time by increasing their rate of herbage intake, and this may contribute to the determination of economic threshold pop

Grazing beef cows ( Bos taurus L.) were exposed to stable fly ( Stomoxys calcitrans L.) and their reactions were related to ingestive behavior. Three concatenated latin squares (4 × 4) were used to evaluate the effects of stable flies on the behavio

A change-over statistical design with complete balance for first residual effects was used with a tethered grazing technique to evaluate the effects of arthropod ectoparasites on the behaviour of adult Angus beef cows (Bos taurus L.; body-weight (BW)

Ectoparasites, at or above certain levels, usually reduce productivity of infested livestock, however the causative processes are often poorly defined. Irritation from non-biting flies may, for example, interfere with grazing behavior and reduce herb

Rapid inhibition of urokinase in plasma obtained from women in the third trimester of pregnancy was assessed by the addition of 75 IU urokinase per ml plasma, and measurement of residual urokinase activity with PyroGlu-Gly-Arg-pNA after 5 minutes inc
