Brown hens raised in industrial system, during a natural moult process. The process of spontaneous moult started towards the end of the laying cycle (63 weeks of age) and lasted about seven weeks. Two groups were set up for monitoring: a control group of hens that did not show signs of moult and an experimental group of spontaneously moulted hens. Blood was sampled weekly, from the moment of observing the onset of moult, to the complete re-dressing with feathers, respectively a period of seven weeks. Haematological parameters showed a specific dynamic during this process. This dynamic is dominated by a decrease in red blood cells, packed cell volume and haemoglobin (P<0.05), on the one hand, and a decrease in the white cell number and in the percentage of lymphocytes (P<0.05) on the other. These changes take place predominantly in the first three weeks of the moult period. In the next period of the process, the modified haematological parameters return to the values comparable to those of the control (P > 0.05).","PeriodicalId":9470,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Nevertheless, following simple continuous sutures, the dehiscence rates remain high. Our objectives were to compare the appositional simple continuous sutures with the inverting Cushing sutures, investigating: suture resistance, bursting pressure, lumen diameters on canine cadavers, as well as survival and complication rates in canine clinical cases. Our ex vivo experimental results indicate that: the efforts to which sutures are submitted to in anastomoses are minimal for the Cushing suture, the differences between the bursting pressure measured for the two types of sutures indicate the superiority of the Cushing suture, the difference in size of the anastomoses’ lumen between the two sutures are minimal. The retrospective analysis of intestinal end-to-end anastomoses (123 - simple continuous sutures and 388 - Cushing sutures) revealed 7 anastomotic complications, all following simple continuous anastomoses. Our results reveal the superiority of the Cushing suture, compared to simple continuous suture, which emphasizes the fact that the Cushing suture should be considered a good option when performing end-to-end jejunal anastomoses in canine patient.","PeriodicalId":9470,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

The antibacterial resistance to gentamicin, streptomycin, oxitetracycline, tylosin, amoxacillin-clavulanic acid, marbofloxacin, tulatromycin, cefotaxime and doxycycline was estimated by Kirby Bauer method and multiple antibiotic resistance (MAR) index was calculated. Strains from Staphylococcus (sciuri and warnerii), Shigella spp., Kytococcus sedentarius, Salmonella spp. and Citrobacter freundii genera and species were identified in the collected samples. The most resistant was a S. warnerii strain, but the MAR index was high (0.33) in 50% of the strains. The most efficient antibiotic was cefotaxime and the least efficient was oxitetracycline. The results indicated the presence of antibiotic resistant ubiquitous and pathogenic strains in the investigated pigs which need caution, since they could express pathogenicity under appropriate conditions which low input farming system could provide.","PeriodicalId":9470,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

A 5-0 cotton ligature was placed, provoking an inflammatory response removed after ten days. One group received one session of PDT; another group received 3 PDT; the last one represented the control group, with no treatment. Clinical evaluation was represented by assessing the body weight, mobility index and bleeding. A rat grimace scale was used to determine the pain. The results showed clinical aspects of periodontitis and healing tissue proved microscopically.

Beginning with the first 2 weeks of CBD oil administration, the patient was already experiencing an improvement in her mobility along with general pain remittance and the amelioration of her 3rd degree lameness, quantified by the Colorado Pain Scale. After 5 months of CBD administration, with no seizures recorded, phenytoin therapy was ceased. After 8 months, phenobarbital was also excluded from the therapeutic protocol, thus making CBD an independent the rapeutic molecule.

Shigella spp. growth was inhibited at serum dilutions of ½-1/32 while much lower ½-1/4 dilutions were active against S. sciuri. In untreated pigs, the sera were inefficient in either stopping or totally inhibiting bacterial growth.

The histochemical results showed the presence of mucin-secreting cells in the examined tissues. An intense PAS positive reaction was found in the surface epithelium cells of the gastric mucosa and in the cells lining the gastric crypts in all the three segments. In the deep glandular structures, the cells of the cardiac and fundic glands are PAS negative, while those of the pyloric glands are all PAS positive. For Alcian blue reaction, the cells lining the gastric mucosa and the crypts in the three regions of the stomach were negative. In the glands, the cells of the cardiac and fundic glands were Alcian negative while in the pyloric glands, a limited number of cells arranged in the deep third of the glands showed a weak positive Alcian reaction. In conclusion, the vast majority of glandular cells in the rat's stomach do not synthesize acidic mucins, except for cells in the deep part of the pyloric glands, which synthesize small amounts of such mucins.","PeriodicalId":9470,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.
