The study evaluated the effects of sire breed (SB: Vienna Blue (VB) and Burgundy Fawn (BF)), parity order (P: 1 = nulliparous, 2 = primiparous, ≥3 = multiparous), slaughter season (SS: spring, summer), and gender (G: males, females) on the meat quality of rabbits reared under an organic production system. They originated from VB and BF sires mated with females derived from a mix of crossbreds (medium- to large-sized breeds). Rabbits were 46 ± 6 days old, they were housed in groups of five in collective cages, fed a pelleted diet, and slaughtered at a live weight of 2.8 ± 0.13 kg. The hind leg meat samples (from 30 VB and 28 BF crossbred...

The aim of this in vitro study was to determine the effect of lead chloride (PbCl2) on rabbit spermatozoa motility and morphology. Lead concentrations in the medium ranged between 0.45 and 11.17 μg/ml; incubation time was 240 min (analyzed immediately after Pb addition followed by 30, 60, 120, 180, and 240 min), and temperatures of the culture environment were 22°C (laboratory), 4°C (refrigerator), and 37°C (incubator). Results were compared with a control group without Pb addition. After 30 min of culture at 22°C, a negative effect of Pb was noted as spermatozoa motility significantly decreased in groups with higher concentrations....

Bovine mastitis is a major disease affecting dairy cattle worldwide. The milk collected from cows with different type of inflammation, including mastitis, is characterized by an increased number of somatic cells (SCC), especially polymorphonuclear cells (PMN). It was proved that the antibacterial activity of PMN generates reactive oxygen species and nitric oxide-derived metabolites. The accumulation of the reactive species correlating with a decrease in the antioxidant activity specific for milk can lead to oxidative and nitrosative stress. The aim of this study was to evaluate the antioxidant/oxidant status in normal cow's milk and in subclinical...

The aim of this study was to compare the effect of four anaesthetics on haematological and biochemical blood profiles in burbot Lota lota L. Blood profiles of burbot were evaluated 10 min and 24 h after anaesthesia with tricaine methanesulfonate (MS 222) (100 mg/l), clove oil (33 mg/l), 2-phenoxyethanol (0.3 ml/l), Propiscin (1 ml/l) and compared to non-anaesthetized control. The tested anaesthetics had no effect on haematological profile of burbot. The exposure to clove oil, 2-phenoxyethanol, and Propiscin significantly (P < 0.01) influenced the level of ammonia and glucose. The level of lactate was significantly (P <...

The effects of thermal manipulation (TM) during late ostrich embryonic development on hatchability, body weight, biochemical and hormonal changes, and the ability of hatching chicks to cope with thermal challenge in days 6-8 of age were examined. At 35 days of incubation, two hundred fertile eggs were weighed and divided into two equal groups with five replicates. The first group was exposed to 36.5°C and 25% relative humidity (RH) (control), while the second group was exposed to 38.5°C and 45% RH for 3 h daily in days 35-37 of incubation (thermal manipulation). At days 6-8 of age, the hatched chicks from each treatment were randomly divided into two...
