The effect of surgical castration with local anesthesia using lidocaine on neopterin, biopterin, and cortisol blood plasma concentrations in piglets was studied. Three groups of 12 piglets were investigated: one group castrated without lidocaine, one group castrated with lidocaine, and one group left as an uncastrated control group handled in the same way as castrated piglets. Blood samples were collected 4 min before castration, and 1 h and 24 h after castration. The time × treatment interaction (P < 0.01) was detected for neopterin concentrations, yielding the result that neopterin was higher (P < 0.01) in castrated piglets...

The effects of sex and colour type on carcass composition, nutrients content, and muscle fibre characteristics of hind leg meat of nutrias raised under intensive conditions were the focus of this study. Thirty-six eight-month-old nutrias of both sexes with three colour types (Standard nutria, ST; Moravian Silver, MS; and Prestice Multicolour, PM) were studied. Live weight was affected by colour type (P < 0.05) and sex (P < 0.001); however, no effects of these variables were found for the dressing out percentage. Crude protein content was significantly higher in males than in females, whereas crude fat content was higher in females....

The effect of different levels of corn oil (CO) and flaxseed oil (FO) on growth performance, blood characteristics, fatty acid composition, and expression of lipogenic genes in the liver of broiler chickens was studied. Two hundred forty female Cobb-500 broiler chickens at the age of one day (body weight (BW) = 46 ± 4 g) were fed a corn soybean meal based diet containing 5% CO (LC), 3.75% CO + 1.25% FO (FO1), 2.5% CO + 2.5% FO (FO2) or 5% FO (FC). Chickens fed FO1 diet had better BW gain (P = 0.049) and gain/feed ratio (P = 0.006) than those fed LC and FC diets during days 1-21 of age. However, for the whole experimental period...

The impact of applying NuPro® (40 g/kg feed) and levamisole (300 mg/kg feed) in European pikeperch (Sander lucioperca) diets with vegetable oils on growth, immunological, hematological, and blood chemical parameters was assayed. The fish were fed the feed containing sunflower and linseed oils (48 and 21 g/kg feed) (group VO) or this feed with levamisole (group VOL) or NuPro® (group VON). The fourth group was fed the feed with fish oil added in the amount of 69 g/kg feed (group FO). The pikeperch were reared for 56 days. Feeding the fish feed supplemented with levamisole or NuPro® increased the immunological...
Effect of rabbit-origin enterocin-producing probiotic strain Enterococcus faecium CCM7420 application on growth performance and gut morphometry in rabbitsOriginal Paper

The interactions between probiotic bacteria and the immune system in animals are known, but particularly in rabbits have not been sufficiently documented. Therefore the present study deals with the effect of the enterocin-producing probiotic strain Enterococcus faecium CCM7420 on the growth performance and jejunal morphometry in rabbits. Forty-eight weaned rabbits of male sex (NZB breed) at 5 weeks of age were randomly divided into experimental (EF) and control group (CG) with 24 rabbits in each group. Each day of the treatment period (21 days), the rabbits in the EF group were administered a fresh culture of the E. faecium CCM7420...
Pedigree analyses of the Zatorska goose populationOriginal Paper

The structure of the Zatorska breed was estimated in the context of the realized conservation program. The level of genetic diversity and effective population size were estimated as well. The following parameters were evaluated: pedigree completeness index, genetic diversity, inbreeding level, individual increase in inbreeding, generation interval, and parameters connected with general condition of the population. The whole population of the Zatorska breed was housed in an experimental farm of the University of Agriculture in Cracow (Poland). Records were extracted from the studbook. Totally 5514 individuals hatched between 1990-2013 (2835 males and...
