Effects of the probiotic (PRO) Lactobacillus plantarum and of the combination of PRO and the prebiotic (PRE) inulin enriched with oligofructose (2%), and PRO with Lini oleum virginale (O) on counts of lactobacilli and coliforms and enzymatic activities in faeces of rats were studied. The rats (n = 60) were divided into 5 groups of 12 subjects. The animals were fed on a high fat diet (10%) for 8 weeks of experiment. Colon cancer was induced by the application of 1,2-dimethylhydrazine (DMH) twice a week in a dose of 20 mg/kg s.c. in groups G2-G5. The rats in group 1 (control 1) received a diet without any supplements. The rats...

The objective of this study was to verify the hypothesis postulating the location of QTL linked marker for milk performance traits in the proximal section of chromosome BTA1 by analyzing the microsatellite BM6438 alleles from heterozygous sires and the milk performance traits of the investigated cattle. The experiment covered 484 Polish Holstein-Friesian primiparous cows, the progeny of three unrelated sires, including 317 cows ‒ the progeny of two sires with 256/268 genotype and 167 cows - the progeny of a sire with 258/268 genotype. BM6438 polymorphism was determined by PCR and polyacrylamide gel electrophoresis....

Summerling (six-month old) noble crayfish fed two forms of freshly decapsulated (FD) Artemia cysts more than tripled their weight during a 75-day experiment under controlled conditions. Final survival rates were at the level of 90%. Feeding commercially available industrially decapsulated cysts resulted in both poor growth and reduced survival (22.2%). Therefore FD Artemia cysts may be an effective diet for crayfish culture, but dehydrated industrially decapsulated (DID) cysts should be used with caution to avoid products of low quality. That should be considered especially in slow feeders such as crayfish because of leaching of nutrients...

An experiment was conducted to evaluate the effect of pea-based diet fed to growing and finishing pigs on performance, carcass and meat quality. Thirty pigs (Slovak White Meaty or crossbred Slovak White Meaty × Pietrain) were tested for the malignant hyperthermia (MH) syndrome using a DNA based test. Pigs were allotted to control and experimental groups (of 10 pigs each, equal for normal - NN and he-terozygotes - Nn and equal for barrows and gilts) with 2 pigs per pen. Pigs receiving the control treatment were fed soybean meal diets. In all diets fed to experimental pigs the soybean meal was replaced by 30% of raw or extruded pea-based meal balanced...

Czech J. Anim. Sci., 2011, 56(3):127-135 | DOI: 10.17221/1300-CJAS
Allometric growth of body constituents and apparent efficiency of amino acid and nitrogen retention were examined in slow-growing laying-type cockerels (SG) and in fast-growing male broiler hybrids (FG) during the growth period from hatch to Day 22. The respective allometric coefficients for water, protein, (N × 6.25)ash and fat in relation to body weight were 0.971, 1.080, 1.096 and 1.284 for SG chickens and 0.977, 1.099, 0.993, and 1.198 for FG chickens. The respective allometric coefficients describing the relationships of water, fat and ash weight with protein weight were 0.894, 1.014, and 1.186 for SG chickens and 0.893, 0.910, and 1.097 for FG...
Effect of different dietary lipid levels on growth performance, slaughter yield, chemical composition, and histology of liver and intestine of pikeperch, Sander lucioperca

Czech J. Anim. Sci., 2011, 56(3):136-149 | DOI: 10.17221/1298-CJAS
In this study, 16-month-old pikeperch, Sander lucioperca, (initial body weight 280 g) were fed three diets with different lipid levels with the aim of determining the impact on the growth performance, hepatic and intestinal histological structure, chemical composition, and slaughter yield of this species. The fish were fed isoproteinaceous feeds (450 g protein/kg feed) containing 60 g lipids/kg feed (group F6), 100 g lipids/kg feed (group F10) and 180 g lipids/kg feed (group F18). No significant differences were noted among the treatment groups in body weight gain and in the feeding coefficients of experimental feeds (P > 0. 05)....
