Specific IgE to proteins from Tribolium confusum (TC), a flour beetle, was detected in 9/125 sera of subjects exposed to rye and wheat flour. TC RAST was not inhibited by Dermatophagoides pteronyssinus, rye or wheat flour. Immunoblot experiments showed specific binding to three proteins from adult TC or pupae, not present in rye or wheat flour. These findings suggest that TC might act as an occupational allergen in a proportion of bakers.

[Nutrient supply of health and sick fluid fed calves].

In the department for calves being fed with fluid feed of a specialised enterprise for calf rearing the daily intake of fluid feed (skim milk improved with milk substitute), concentrated feed and hay of a total of 341 female animals and the daily intake of energy and protein was calculated thereof. The average consumption of nutrients of the 206 healthy calves was compared with some international and national norms for the demand of nutrients. The comparison with some international values of demand and the results of the partial correlation analysis between energy and protein intake and live weight increase showed that the applied nutrition regime (particularly the kind of fluid feed) has resulted in an excessive supply of the calves with proteins and an insufficient supply with energy. This could not be realised from the GDR nutrients norm for the raising of calves published in 1976. Based on theoretical considerations and some recent findings of the science of nutrition we derived values of the protein and energy demand of our own. Subsequently an attempt is made to assess the supply with nutrients for sick calves.

[Effect of diseases on the nutrient intake by suckling calves].

An energy and protein intake test was applied to 341 female nursed calves under production conditions. Their daily intakes of skim milk enriched with milk substitute, fodder concentrates, and hay were recorded and their daily energy and protein intakes calculated. Their feed consumption was characterised by cumulative nutrient intake curves, depending on the time of foremilk feeding (K-I-period). Energy and protein intake figures were related to the findings obtained from daily health control, with the view to defining the effects of pneumonia or diarrhoea on feed intake. Both diseases were found to cause significant reduction in nutrient intake, depending on the given type of disease and severity, with their negative impact having been most markedly shown in the context of dry feed intake. The delay caused to the development of dry feed consumption by diseases of the respiratory and digestive tracts was many times longer than the time of the clinical course. The above observations provided some cues for conclusions regarding the approach to be taken by the veterinarian to diagnosis, therapy, and rehabilitation of affected calves. Certain concepts were derived from the findings as to how to feed calves to forestall developmental disorders.
