The efficacy and tolerance of Remophan (Spofa), prostaglandin F₂ alpha analogue was examined on 52 mares from individual farms without a visible signs of oestrus (42) or with oestrus only slightly recorded (12). It was found that Remophan was very effective. The side effects were confined to restlessness and a slight perspiration. Remophan may be used in mares under veterinary control if there is a lack of prostaglandin F₂ alpha preparates for horses.
Penile prolapse can be a result of trauma, administration of phenotiazine tranquilizers, habronemiasis, large tumours, neuropathies, equine infectious anemia, purpura hemmorrhagica, spinal cord lesions and infammation (EHV-1, rabies). Penile prolapse is often associated with paraphimosis or results from the relaxation of musculus retractor penis which is caused by senility, severe general debilitation or exhaustion and starvation. Prolonged prolapse can be confused with the penile paralysis or priapizm. This article presents the case of a seven-year-old stallion with irreversible changes in the penile resulting from the lack of veterinary care after trauma as well as general severe debilitation. The lesions involved the glans penis, the free part of the penis and the inner lamina of the preputial fold. Those structures could not be identified for they composed an ulcerative, granulomatous mass with areas of fibrosis which was limited by the fibrotic preputial ring. Considering the irreversible injury of the prolapsed penis and the horse’s inability to copulate or properly urinate, it was referred for phalectomy. In the presented case a direct complication after penile amputation was an abscess of corpus cavernosum penis. One month after surgery, impeded urination resulting from the narrowing of the urethra was observed. Then a plastic surgery of the urethra was performed. Examinations performed three and six months after urethroplasty revealed no disturbances in urination or protruding and retraction of the penile stump. Considering serious consequences that may occur after the penile prolapse, one should immediately provide proper medical treatment, which can help to avoid the development of irreversible changes in the prolapsed organ and preserve the stallion’s reproductive function.
The aim of the study was to investigate the influence of pharmacological synchronization of ovulation and reinsemination on the number of litters in gilts and sows. The investigations were done on 207 gilts and 206 sows. Ovulation was synchronized by the use of Receptal (2 ml/animal) or Chorulon (500 iu/animal). Reinsemination was performed 24 h after the first insemination. It was found that reinsemination and ovulation synchronization significantly increased the number of piglets in litters of gilts and decreased the number of still born piglets. The procedure used did not significantly increase the number of piglets in litters of sows. However, it decreased the percentage of still born piglets.
The investigations concerned the influence of ivermectin on the biological value of the sémen of boars. The quality of the semen was evaluated on the basis of a preliminary estimation of spermatozoa concentration in ejaculates, the percentage of spermatozoa mortality and the morphological picture of spermatozoa. The aim of the study was also to estimate a fecundating value ot the semen by determining the percentage of sows which repeated oestrus after 21 days from insemination with the semen of the experimental boars. A decrease in spermatozoa survival within two weeks after the administration of ivermectin was found.
Komputerowe wspomaganie problemów analityczno-decyzyjnych w budownictwie mostowym wymaga stosowania różnorodnych technologii informatycznych, takich jak bazy danych i systemy wspomagania decyzji, w tym systemy sztucznej inteligencji. Hybrydowe rozwiązania informatyczne, integrujące działania wskazanych technologii, są określane mianem inteligentnych baz danych. W opracowaniu przybliżono uwarunkowania zastosowania inteligentnych baz danych w obszarze budownictwa mostowego. Jako rozwiązanie o szczególnym znaczeniu wskazano dedukcyjne bazy danych, stanowiące połączenie tradycyjnych baz danych z systemami wnioskowania regułowego. Mogą one być z powodzeniem wykorzystywane np. w przedsięwzięciach doboru konstrukcji mostów tymczasowych czy monitorowania stanu obiektów mostowych, a uzupełnione o moduł sztucznej sieci neuronowej dodatkowo wspomagać realizację przedsięwzięć o charakterze predykcyjnym.
The objective of the studies was to evaluate the hygienic quality of raw milk from individual milk producers during a one year period. The total number of bacteria in one ml of milk was evaluated by the use of BACTO-SCAN 8000 equipment. It was found that the percentage of producers of the highest hygienic quality milk (up to 10⁵ bacterial cells/ml of milk) was significantly higher in winter (9.2%) and in spring (12.89%) than in summer (1.57%) and in autumn (1.44%). The highest number of producers of milk of the lowest quality (more than 10⁶ bacterial cells/ml of milk) was in summer and in autumn. It is suggested that the higher percentage of producers of milk of a good quality in winter and spring resulted from better conditions for milk cooling. Probably most milk producers cool milk in cold water or at room temperature. The observed differences in bacterial contamination of milk during a one year period indicate the necessity for using special equipment for milk cooling.
