Toxoplasmosis was diagnosed in two goat herds in the Czech Republic. The 1996 outbreak in the herd of Angora goats was associated with abortions and births of weak kids. No apparent signs of toxoplasmosis were observed in the herd of White Short-Haired (WSH) goats reared under similar conditions. Seroprevalences of 60% and 66% tested by complement fixation(More)
The in vitro monolayer proliferation assay (MP-assay) described here enables predictive determination of the efficacy of anticancer drugs considered for clinical application. The assay was designed (1) to achieve a high plating efficiency, (2) to adapt in vitro growth as close as possible to in vivo conditions, and (3) to prove that the cells in vitro(More)
From the toxicological point of view, in the last two years melamine and cyanuric acid have become matters of great interest. These substances, especially melamine, have been abused during food and feed adulteration by increasing the content of nitrogen compounds in these products. Melamine and cyanuric acid as individual substances do not pose any serious(More)
Amino acid content before and after heat treatment was assessed in grain of six selected amaranth varieties and four species: Amaranthus cruentus, A. hypochondriacus, A. caudatus and A. hybridus, cultivated in the Czech Republic. High content of Lys and Arg was detected in both heat treated and untreated grains, as well as satisfactory content of Cys and(More)
The average digestibility coefficients of feed mixture nutrients in pigs infected medium severely to severely by the helminths Ascaris suum and Oesophagostomum dentatum were lower in comparison with the post-dehelminthization condition (dry matter by 3.1%, crude protein by 6.7%, fat by 8.9%, nitrogen-free extracts and fibre by 2.2%, organic matter by 3.1%).(More)
The objective of this study was to examine iodine and selenium contents in skeletal muscles of selected species of game animals living in regions with low iodine and selenium contents in the soil and water. Iodine content was determined in 66 samples of skeletal muscles of red deer cut out of the musculus gracilis, 32 samples and 27 samples from the same(More)
The following characteristics were determined in raw and popped amaranth grain: crude protein (158.1 and 168.5 g/kg), ether extract (71.5 and 69.4 g/kg), neutral detergent fibre (NDF) (99.2 and 111.8 g/kg), cellulose (86.6 and 60.0 g/kg) and essential amino acids (Cys 4.2 and 4.1, Thr 6.0 and 6.5, Ala 8.8 and 9.2, Val 6.8 and 7.4, Ile 5.2 and 5.6, Lys 9.2(More)
Urinary iodine concentrations were determined in 672 dairy cows of 22 herds. Less than 20 micrograms per L, 20 to 50 micrograms per L, 50 to 100 micrograms per L and more than 100 micrograms per L were found in 27.5, 24.6, 16.8, and 31.3% of the cows, respectively. In terms of the ICCIDD grading, moderate iodine deficiency was recorded in 68.9% and normal(More)
