Immobility of pigs is a reason for emergency slaughter. The goal of this project was to determine the proportion of emergency slaughters due to immobility in pigs. In a selected pig slaughter facility, emergency slaughters were monitored in the period between 1997 and 2002 and the numbers of pigs slaughtered due to immobility reasons were monitored. The conclusion was that the proportion of sows slaughtered due to immobility reasons is high (31.3%) in comparison to other pigs (9.7%) and this difference was found to be statistically significant (P < 0.01). The objective of the project was also to determine the causes of immobility in emergency...

The aim of the present work was to determine the most frequent causes of emergency slaughters in pigs and the trends of future development. Records from emergency slaughters of pigs all over the CzechRepublic were studied for the period of 1997-2002. The causes of emergency slaughters were divided into the following groups: infectious diseases, respiratory diseases, digestive diseases, musculoskeletal diseases, complications post partum, diseases of miscellaneous aetiology. The trends of future development were determined as an index equal to the ratio of relative occurrence of the findings during the period of 2000-2002 to the same figures...

The aim of the present study was to correlate the milk production and the kinetic variables in milk of cephalothin administered to goats. Twenty healthy creole goats in milk production were used. Cephalothin was administered by intravenous route (20 mg/kg b.w.). Milk samples were collected at 0.25, 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 8.0 and 12.0 hours postadministration of the antibiotic. Cephalothin concentrations were measured in milk samples by high performance liquid chromatography. The values (mean ± standard error) of milk production collected during 24 hours previous to the administration of the antibiotic were 761.5 ± 111.1 ml....

The objective of the present study was to investigate the importance of the antioxidant enzymes; glucose-6-phosphate dehydrogenase (G6PD), glutathione reductase (GR), superoxide dismutase (SOD), glutathione peroxidase (GP) and catalase (CAT) in defense against toxic reactive oxygen species (ROS). For this purpose, comparative studies were performed on the antioxidant enzyme activities in red cells of rainbow trout (Oncorhynchus mykiss) between flow-through and recirculated breeding systems G6PD, GR and SOD activities were found significantly lower in reuse system than flow-through system. But, GP and CAT activities were increased significantly...
Tuberculous lesions in pig lymph nodes caused by kaolin fed as a supplement

An increased incidence of tuberculous lesions in head and mesenteric lymph nodes from slaughtered pigs weighing about 115 kg was recorded in a herd of pigs kept in two farms A and B in the CzechRepublic. Tuberculous lesions were more frequently (P < 0.01) diagnosed in pigs from Farm A (10.4%) than from Farm B (1.1%). The follow-up investigation of potential sources of infection on Farm A revealed that the piglets were fed kaolin from a nearby mine as a supplement. Among 20 samples from the pigs' environment, atypical conditionally pathogenic mycobacteria (ACPM) were detected in four samples as follows: dust (n = 2), pig faeces...
Kaolin, bentonite, and zeolites as feed supplements for animals: health advantages and risks

Feeding kaolin as a supplement to pigs for prevention of diarrheal diseases has been introduced into some farms in the CzechRepublic. Peat was used in the 1990s for a similar purpose; however, most farmers ceased feeding peat as a supplement because of its frequent contamination with conditionally pathogenic mycobacteria, esp. with Mycobacterium avium subsp. hominissuis. The aim of the present paper is to review available literature from the standpoint of the advantages and disadvantages related to feeding kaolin as a supplement to animals. Its positive effects exerted through the diet primarily consist in its adsorbent capability...
