Effect of duration of PMSG treatment on induction of oestrus, pregnancy rates and the complications of hyper-oestrogenism in dogs.

In anoestrous bitches, the use of 5 or 10 days of daily PMSG treatments (20 i.u./kg/day) before a single injection of hCG (500 i.u./dog) did not affect the timing of induced pro-oestrus (4-6 days) but did result in a greater incidence of conception (3 of 6 vs 6 of 17), a high rate of successful pregnancy (50% vs 0%), lower preovulatory oestrogen concentrations, and reduced incidence of complications due to hyper-oestrogenism such as thrombocytopenia (0% vs 29%). These results suggest an advantage of 5 over 10 days of priming with PMSG, at the doses used before hCG injection, for induction of fertile oestrus in bitches.

[Clarification of teat stenoses in cattle by ultrasound].

Ultrasonography and radiography were used as an adjunct to clinical examination in the evaluation of 73 obstructed teats in 63 dairy cows. The images obtained with a 3.5 MHz and a 5 MHz linear array transducer were compared with radiographs and correlated with findings obtained at surgery. Ultrasonography and radiography allowed a correct assessment of the lesions in 68 respectively 58 teats. In five cases the obstructive lesions in the teat canal were not clearly discernible when ultrasonography was used. Radiography was the method of choice for the evaluation of the teat canal and small mucosal folds in the milk cistern. Ultrasonography was the method of choice for the detection of obstructive lesions at the base of the teat; all 14 of these cases were assessed correctly using ultrasonography versus three of 14 when radiography was used. Ultrasonography is a useful tool for the practitioner to evaluate obstructive teat lesions.

[Urinary incontinence in spayed female dogs: frequency and breed disposition].

A follow up study was performed in 412 spayed bitches in order to determine the incidence of urinary incontinence. The period between the operation being performed and the survey being made varied between 3 and 10 years. 83 animals (20.1%) were incontinent independent of the surgical procedure (ovariectomy versus ovariohysterectomy). The onset of incontinence varied between immediately to 12 years with an average period of 2.9 years after surgery. 57 of these incontinent bitches were treated with ephedrine or estrogen. In 73.7% a good response was achieved with ephedrine and a further 23.7% showed some improvement. Generally ephedrine was more successful than estrogen in the treatment of incontinence. There appears to be a strong connection between body weight and the incidence of incontinence. Of bitches with a body weight of less than 20 kg only 9.3% were incontinent. Whereas in bitches with a body weight of more than 20 kg the incidence was 30.9%. Of the breeds Boxers showed a high incidence of incontinence (65%) while breeds such as German Shepherds (10.6%) or Dachshunds (11.1%) showed a low incidence in relation to the average incidence rate (20.1%).
