摘要:

A new chemotherapeutic agent, pipemidic acid, was used to treat 14 dogs and 2 cats with recurrent urinary tract infection caused by multiresistent strains ofEscherichia coliandProteusspp. Bacterial culture of the urine after treatment revealed disappearance of the microorganisms in all patients.

摘要:

Lymph node biopsy was performed on animals older than nine months on a dairy farm which carried 223 animals and was severely affected by paratuberculosis. Biopsies were examined histologically and bacteriologically for the presence ofM. paratuberculosisinfection. In this way Paratuberculosis infection was diagnosed in 29 animals, in which other diagnostic methods (serum complement fixation test, intradermal johnin test and microscopic examination of the faeces) produced negative results. The value of lymph node biopsy is the early detection of infected animals. In the two years after the biopsies, no further cases of clinical paratuberculosis were detected on the affected farm, although infection withM. paratuberculosispersisted.

摘要:

Forty‐one dairy cows were fed a low (LCa ‐ 13 g/d) and a high (HCa ‐ 83.5 g/d) calcium ration in the 8 weeks prior to parturition and the effect on the Ca mobilization rate around parturition was studied. Plasma Ca values were stable in the LCa group around parturition. In the older cows of the HCa group a very slight decrease in the mean plasma Ca was observed: 2.58 mmo1/1 at 12 ‐ 36 h ante partum decreased to 2.38 mmol/l at parturition.

摘要:

The influence of a low and a high prepartum calcium (Ca) intake on Ca mobilization rate around parturition was studied in 44 dairy cows fed a ration sufficient for. 1.90 times maintenance requirements during the dry period. The plasma Ca level declined on the day of parturition in the group fed the low Ca intake (LCa: 26.4 g/d) as well as in the group fed the high Ca intake (HCa: 87. 2 g/d). Plasma Ca levels of the 11Ca group were lower at parturition. and in this group 1 cow had milk fever after parturition. In the HCa group 6 cows had a plasma Ca level ≤ 2.0 mmo1/1 at parturition and/or 10 h post‐partum (pp), versus 1 cow in the LCa group. Na2EDTA was intravenously infused at 10 h pp to induce hypocalcaemia to a level of plasma Ca not bound to EDTA of approximately 1.0 mmol/l. The LCa groups tended to require more Na2EDTA than the HCa groups, however the difference was significant only in the younger cows. After the Na2EDTA infusion 7 cows of the HCa group and I of the LCa group did not recover spontaneously and needed to be treated. The mean plasma PTH levels of the LCa group ante‐partum were slightly higher than those of the HCa group. The Ca level of the prepartum ration did not influence urinary hydroxyproline excretion, which suggests that the Ca intake of 26.4 g/d was too high to stimulate bone turnover.

摘要:

The farrowing index is an important parameter for the evaluation of sow productivity. The value of the farrowing index calculated over a relatively short period of time and converted to a yearly basis, depends largely on the number of litters produced during this period. Random differences in the numbers of litters produced in subsequent periods will strongly influence the farrowing indices of these periods.

摘要:

The results of a retrospective study of 23 goat kids with delayed swayback are reported. Principal clinical signs were ataxia, loss of postural control, spasticity of the hindlimbs, and muscular weakness, often progressing to permanent recumbency. Denervation of skeletal muscles was demonstrated by electromyography in 2 kids. Three kids slowly recovered during hospitalisation.

摘要:

Literature concerning the ototoxicity of the antiseptic combination chlorhexidine/cetrimide chlorhexidine/cetrimide (Savlon®): effects on equilibrium and hearing (Savlon®) is reviewed The ototoxic effectsare illustrated by the results of our own experiments in guinea pigs. The impetus for this article was the observation of vestibular dysfunction in 15 clinical cases (12 dogs and 3 cats), in 8 of which it was confirmed that the ear canal had been rinsed with this drug combination in the presence of a ruptured tympanic membrane.

摘要:

An outbreak of caseous lymphadenitis in which three herds of goats were involved is described. Corynebacterium pseudotuberculosis was shown to be the causative organism. The outbreak was associated with imported goats. As this first report ofC. pseudotuberculosiscausing caseous lymphadenitis as a clinical entity in small ruminants in the Netherlands, clinical and epizootiological aspects as well as possible methods of control are discussed.
