The weaning time is a crucial period in the management of piglets. The risk of development of post-weaning diarrhoea (PWD) in piglets is high. PWD is the cause of serious economic losses in pig herds. Since 2006, the use of antibiotic growth promoters for prevention of diarrhoeal diseases in piglets has been banned. This measure also led to the investigation of alternative suitable feed supplements that would be reasonably efficient in protecting and sustaining animal health and performance. Various natural materials such as probiotics, prebiotics, organic acids, zinc and plant extracts have been tested as effective alternatives to antibiotics. Recently,...

Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of paratuberculosis (Johne's disease) in ruminants. Paratuberculosis can cause severe economic losses and is acknowledged as one of the most important diseases of ruminants today. High amounts of MAP can be shed in the faeces of infected individuals and can survive for a long period in the environment. In the presented trial, baled grass silage was inoculated with a MAP-suspension, and the viability of MAP was studied over time. Samples from the bales were taken at increasing intervals and subsequently tested for the presence of MAP...

Fresh and frozen seafood products (fish, shellfish, crustaceans, molluscs) in wide use in Croatia and typical of the Mediterranean diet, were examined for the presence of microbiological contamination through the winter and summer seasons. Total bacterial counts of aerobic mesophilic bacteria (AB), aerobic psychrophilic bacteria (AP), Salmonella spp., Enterobacteriaceae, Escherichia coli, Staphylococcus aureus, sulphite-reducing clostridia (SRC), Listeria monocytogenes, Vibrio cholerae and V. parahaemolyticus were measured. The microbiological quality of individual samples varied widely between animal species and...

The study was carried out on nine sexually mature male rats of the Wistar breed weighing approximately 250 g each. Animals were anaesthetized with thiopental sodium injected intraperitoneally (30 mg/kg of body weight). The animals were then injected with Fast Blue tracer into the right trapezius muscle. After a survival period of five weeks the rats were transcardially perfused with buffered paraformaldehyde. The following tissue blocks were collected: spinal cord (cervical and thoracic part) with spinal ganglia and whole brain with medulla oblongata. The tissues collected were cut into 12 μm-thick cryostat sections, which were viewed under a fluorescent...

Penetrating cranial injury due to gunshot in a dog: a case report

A ten-month old, male Black and Tan Coonhound dog was referred with ocular bleeding due to gunshot injury. His mental state was normal. A computed tomography revealed that the bullet was planted in the left cranium. It was presumed that the trajectory of the bullet penetrated from the right medial angle of the eye to the orbit, and changed its track to caudo-dorsal by penetrating the cranium, ending up at the left cranium. The bullet was removed by lateral rostrotentorial craniectomy. No complications were observed during a one-year follow-up except the blindness in the right eye. This is a rare case of gunshot-induced traumatic brain injury featuring...
