The objective of this study was to estimate the impact of somatic cell count (SCC) in early lactation (SCCel) [measured between 5 to 14 d in milk (DIM)] of dairy heifers on test-day milk yield (MY) during the first lactation.In total, 117,496 four-weekly test-day records of 14,243 heifers were used....

Twenty-eight Simmental-cross steers weighing 200 (+/- 20.5) kg were used to evaluate grass and whole plant lupin silages in terms of growth rate, dry matter (DM) intake and carcass characteristics. The chemical composition of the silages was determined and Dacron bag procedures were used to estimate...

In Experiment 1, 24 multiparous cows in early lactation were given a basal diet for ad lib. intake consisting of 24.3% (DM) maize silage, 25.9% whole crop barley silage, 33.1% lucerne silage and 16.7% of a protein supplement. Raw barley grain, or barley flame roasted to reduce its rate of rumen degr...

The following studies were designed to evaluate plasma elimination kinetics of intravenously administered antipyrine, acetaminophen and lidocaine among 9 healthy adult horses and 9 healthy drug-free humans (3 each per drug group), in order to compare potential species differences in drug-metabolizin...

OBJECTIVE: To determine a range of limb loading activity for healthy adult horses confined to box stalls in an equine veterinary teaching hospital and determine the effects of hospital environmental factors on load rates and daily limb loading patterns. ANIMALS: 6 mature healthy horses of various ag...

OBJECTIVE: To derive pharmacokinetic data for 3 amikacin dosing regimens in guinea pigs and to determine whether the antibacterial activity of 15 mg/kg of body weight given twice daily is equivalent to administering the drug more frequently. ANIMALS: 10 guinea pigs in pharmacokinetic trials, and 10 ...

The effects of dietary particle size on the prevalence and severity of gastric ulcers were examined in 80, individually housed Yorkshire pigs (24.1±2.9 kg) fed ad libitum on finely ground (particle size 578±1.89 μm), maize-wheat diet for 2 weeks. All pigs were examined endoscopically, and ulcers ...

Osteopontin has been identified as a marker of metastasis formation and its increased expression has been correlated with the malignancy of cancer. In this study we provide evidence that increased expression of osteopontin may also be associated with progression of Bcr-Abl-expressing leukaemia cells...
