A 4.5-kg urachal abscess involving the umbilical arteries was diagnosed in a 12-week-old Holstein heifer. The urinary bladder wall was adhered to the mass, and there were multiple adhesions of the jejunum, which were associated with incomplete extra-mural obstruction. Adhesiolysis was completed. One...

The objective of this paper is to describe the 1000 head grower/finisher swine research unit and how it addresses the research needs associated with the growing and finishing phases of pork production, including integration of manure studies with studies of other production variables. The facility u...

When designing both regional and herd-specific mastitis control and research programs, recent knowledge about the distribution of clinical and subclinical pathogens, as well as the frequency of adoption of mastitis prevention practices have to be considered. The objectives of this study were to esti...

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....

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 ...
