A screening was carried out for CVM, BLAD, DUMPS, bovine citrullinaemia, glycogen storage disease V, and Robertsonian translocations in the cattle population of the Czech Republic. In 406 Holstein sires and 146 Czech Pied (Czech Simmental) sires entering the AI programme in the Czech Republic from 2003-2005, no heterozygous sire for DUMPS, bovine citrullinaemia and BLAD was found. The heterozygote was not found also in the beef sires of Charolais, Limousine, Beef Simmental, Blonde d'Aquitaine, Belgian Blue, Aberdeen-Angus, and Hereford breeds. In 111 elite Holstein females, 21 (18.9%) were heterozygotes...

The aim of this study was to test whether a more pronounced oxytocin release induced by naloxone during milking causes higher efficiency of milk removal. Eight pregnant multiparousHolsteincows from second to fifth lactation were used for this experiment. The experiment was carried out during three consecutive days, i.e. six milkings (three morning and three evening milkings). During first and third evening milking in cross over design (four and four animals) 250 mg of naloxone or 10 ml saline was injected 5 min before the start of udder preparation. During these milkings 2 IU of oxytocin was injected i.v. after stripping and the amount of milk obtained...

The purpose of this study was to evaluate the influence of high lipid concentration in the diet, served as calcium salts of fatty acids from rape, on metabolism and the milk yield of dairy cows during the first third of lactation. 28 dairy cows were divided into experimental (E; n = 14) and control groups (C; n = 14) and monitored within 100 days of lactation since the day of parturition. The diet of both groups had a balanced content of energy and crude protein, while there was a difference in lipid content (C - 3.7% vs. E - 6.99% of dry matter in the diet). Blood and urine samples were taken at the end of 1st, 2nd...

-Lung hemorrhage in a green iguana (Iguana iguana) with chronic metabolic failure: a case report

Vet Med - Czech, 2006, 51(6):356-363 | DOI: 10.17221/5556-VETMED  

A six year old male iguana (Iguana iguana) was brought to our clinic after a fall from a height of 1.5 meters. The patient showed apathy, dehydration, and paresis of all the limbs. Postural reflexes, palpebral reflex, and response to painful stimuli were minimal. The patient had extremely high levels of uric acid (1 734.0 µmol/l) and phosphorus (9.80 mmol/l), ratio of calcium to phosphorus (0.18), leucocytosis (23.3×109/l) with heterophilia (17.10×109/l), and high activity of ALT, AST and CK (2.09, 6.59, and 260.0 µkat/l). Tracheoscopy and pneumoscopy revealed presence of blood clots in the trachea and lungs...
