Unlike most mammals, chicken lactate dehydrogenase isoenzymes cannot be separated using the 'Titan-Gel' electrophoresis. However, using isoelectric focusing at a pH range of 3.0 to 9.0, a good and clear separation of all five isoenzymes was achieved. Generally, three characteristic groups were seen: (a) those having a cathodic domination (breast muscle and(More)
Hematology and serum chemistry measurements were performed on blood specimens from 12 male Dunkin-Hartley hairless guinea pigs Crl:IAF(HA)BR and 10 haired Dunkin-Hartley male guinea pigs Crl:(HA)BR. Significantly higher activities of alanine aminotransferase, aspartate aminotransferase, amylase, and creatine kinase were observed in the hairless guinea pigs(More)
Cystitis, urethritis and pyelonephritis in cattle most commonly result from ascending urinary tract infection with Corynebacterium renale, Corynebacterium cystidis, Corynebacterium pilosum or Escherichia coli. We describe the clinical, bacteriological, clinical-pathological and epidemiological findings in a dairy cattle herd with urinary tract infection(More)
The effect of long term hyperthermia on enzyme levels in the chicken heart and breast muscles, brain, kidney, liver and lung were studied. Three weeks old chickens were exposed to environmental temperature of 24 degrees C (control group) and 32 degrees C (experimental) for a duration of 5 weeks, after which the birds were sacrificed, organs removed,(More)
Ca soaps of fatty acids (CSFA, 0.5 kg/d) were added to the diet of lactating cows for 170 d, and production, body condition score and blood lipids were examined. Production of fat-corrected milk was increased by 1.5 kg/d owing to increase in both milk and fat production. Over 250 d lactation, production of fat-corrected milk was enhanced by 1.3 kg/d. Body(More)
The effects of a sudden addition of a large quantity of readily fermentable carbohydrate to the feed ration of pregnant heifers are described. Clinical and pathological changes caused by the resulting disease were confined to the digits and skin. The 4 acutely affected heifers were reluctant to get up or move (group II). They tended to lie down or stand(More)
Beagle dogs were examined during the subclinical phase of canine ehrlichiosis under controlled conditions. Emphasis was placed on gathering data before artificial inoculation with Ehrlichia canis, and comparing these data with those of the subclinical phase of the disease. In this study all dogs were clinically healthy throughout the 6 month examination(More)
A qualitative field test for determining the blood level of the enzyme gamma-glutamyltransferase is described for the evaluation of colostral ingestion. The method for enzyme determination is based on dry chemistry technology, and a simple 37 degrees C incubator and colour chart for estimating the activity. There were good correlations between results(More)
