The study was performed on two groups of lambs: control (CG) and experimental (EG) in which diet was supplemented with Saccharomyces cerevisiae yeast extract. At 100 day of life, 13 lambs from each group were weaned, fasted for 12 h and, on the following morning, transported to the slaughterhouse. Lambs were weighed and subjected to blood sampling before weaning (blood sampling time (BST 1), before...
The aim of this study was to assess the relationship between living conditions (microclimate, aerial contaminations, box dimension, access to the paddock/pasture) of horses kept in 3 stables and physiological indicators (protein and its fractions in serum, haptoglobin). The study was carried out for 4 months during autumn and winter in 3 stables. Blood samples were collected from 10 clinically healthy...
The aim of this study was to determine the effect of different variants of pre-slaughter procedures in the winter on body weight loss in broiler chickens, and on the proximate chemical composition and physicochemical properties of meat. At the completion of a six-week rearing period, 240 ROSS 308 chickens were subjected to the following variants of pre-slaughter transport: no transport (N-T), transport...
The aim of this study was to compare the breeding environmental conditions in the box stall stable and the horse-barn. Assessment of the breeding environment was performed on the basis of the stable area and the cubic capacity as well as on microclimate measurements over the autumn and winter period. The results of the study indicate that both the box stall stable and the horse-barn provided a proper...
The aim of the present study was to evaluate the degree of microbial air contamination in three laboratory rooms designed for raising broiler chickens under identical conditions, in the summer and winter. It was found that in identical poultry houses and under identical management conditions, certain differences can be observed with regard to temperature and humidity parameters and the degree of microbial...
Levels of Cortisol in blood serum of 50- and 100-day-old rams of Kamieniecka sheep (K) and its crossbreds (F,) with Berrichon du Cher (KxBCH) and Blackhead (K x B) rams before pre-slaughter handling and after slaughter were determined. No relationship between the Cortisol levels and the genotype of the animals were found. However, age-dependent differences in the concentrations of the hormone (P ≤...
Analysis of 102 Polish Duchenne/Becker muscular dystrophy (D/BMD) patients was performed by multiplex amplification of 22 fragments of the DMD/BMD gene and deletions were found in 55% of the patients. The data obtained using PCR were compared with results of 25 Southern blotting and hybridization experiments with cDNA probes and with immunostaining using anti-dystrophin antibodies. In order...
