The influence of the ionization on the air dustiness in the pig weaners
MATĚJKOVÁ, Eva
The observation was performed in brick building for the pig weaners. The stabling was created as group litter pens. The porkers was batten on fodder. The aim of the work was evaluationed microclimate of stable and the influence of the ionization on the air dustiness. The temperature, the relative humidity, the rapidity of atmospheric circulation, the cooling-down temperature and dustiness was measured in the pig house. The ionization was practised in stable and than was evaluation the influence of the ionization on the air dustiness. From the measurement was found out, that the ionization of the air was positive affect low particle concentration of dust. Effect of the ionization on the air was the highest during feeding-time.

The occurrence of Coccidiosis in the intestine of sucking pigs before and after weaning
KOTILOVÁ, Jiřina
In two years of observation, (spring 2006, autumn 2006, spring 2007 and autumn 2007) were being screened for parasites in total 495 faecal samples coming out of three farms from Ceske Budejovice (285 samples of sucking pigs not older then 28 days and 174 samples of piglets not older then 8 weeks). The method used to examine those samples was a flotation-concentrating method (Sheather{\crq}s carbohydrate fusion) and in the year of 2007 was also used a specific aniline-carbol-methyl violet staining method to detect the Cryptosporidium spp. followed by positive molecular characterized (direct sequencing of partial SSU rRNA partial genes and PCR-RFLP at the SSU rRNA). In screened samples were mainly detected parasites named Cryptosporidium spp., found in 4,1% of faecal samples in 2006 and in 2007 in 32,8% faecal samples, out of which 14,4% was found in pre-weaned piglets samples and 26,4% in post-weaned piglets. Based on genotyping provided on positive samples out of the year 2007, using method of sequensing analysis SSU rRNA, was the occurence of C. suis, Cryptosporidium pig genotype II aC. Muris described. High prevalence of Isosporou suis 13,9 % (64/459) was also detected with its appearance, in particular, in pre-weaned piglets 21,4 % (61/285). Further on, some of other identified group was Eimerie spp. 5,7 % (26/459) infecting, in the main, post-weaned piglets 10,9% (19/174) and Giardia intestinalis 2,4 % (10/459). Most of the samples mentioned occured in conditioned faeces and there is no seasonal relationship to the parasital occurance.

Influence of stable environment temperature on sucking-pigs health
PRŮŠOVÁ, Jitka
The aim of the work was determined impact of microclimatic parameters of stabling environment at percentage of pregnant sows, and at health of sucking and young growing pigs. In sucking and young growing pigs were founded weak positive correlation between stabling temperature and mortality of weaning pigs, and weak positive correlation in comparison to humidity. There were founded strong negative correlation between grow up temperature of the environment and percentage of success pregnant sows, and strong positive correlatin in relation to relative humidity. Influence of the cooling ability of the environment and air flow speed were lower than the impact of the temperature.

THE OCCURRENCE OF COCCIDIOSIS IN THE GUTS OF SUCKING PIGS BEFORE AND AFTER WEANING.
ČIVIŠOVÁ, Jana
In the whole, 487 samples have been collected from two farms in the Kladno region during the time periods as following: Autumn 2004, Winter 2005, Spring 2005,Autumn 2005, Winter 2006 and Spring 2006. For the investigation of the parasite presence in the dung the flotation-concentration method (Sheather sugar solution) and specific aniline {--} carbolic - methylviolet colouring according to Miláček and Vítovec (1985) with followed microscopy investigation at 200 - 400× magnification have been used. The infections caused by Cryptosporidium spp., Eimeria spp., Isospora suis, Giardia intestinalis, Trichuris suis, Ascaris suum and Strongyloides ransomi have been found in the samples. For the most part, the infection caused by Cryptosporidium spp. (19.1 %), Eimeria spp. and Isospora suis (5.2 %) have occurred in the breeds. Prevalence of the Giardia intestinalis flagellates have reached to 2.9 % and 5.4 % for nematodes Majority of the positive samples had solid consistency of the dung. The smallest occurrence of the parasites have been diagnosed in the winter 2005. On the contrary the greatest occurrence have been diagnosed in autumn 2005.
