[Effect of a short-term diet based on precooked corn flour on the muricidal behavior of male SM Wistar rats].
The aim of this research is to observe if the lack of cerebral serotonin, obtained by a diet almost devoid of tryptophan (precooked yellow corn meal) is able to trigger the muricide behaviour in male Rats naturally non-muricide. To determine the tryptophan content in the food used and in 4 types of selected maize flour (Zea mays: indurata, indentata, opaque/2 and synt. marano), 3 different methods have been used (ion-exchange chromatography, spectrofluorometry, spectrophotometry). The muricide behaviour, or the interspecific attack, has been tested by comparison Rat-Mouse. The results show that the feeding with a diet "short term" (4 days), composed of precooked corn meal, with a very low content of tryptophan, induces the appearance of muricide or aggressive behaviour towards the Mouse in more than half of the Wistar Rats, bred in a room constantly lighted by sodium steam light. The appearance of the above-mentioned behaviour is connected with the decrease in cerebral serotonin.
