The nutritional problems associated with poultry feeding are complex and require basic as well as applied research. The research topics maintained during the time period of 1989-1996 can be grouped into several categories such as: nutritional effect of amino acids, biological value of protein sources, effect of feed additives, as well as the physiological role of heavy metals. The biological efficiency of a lysine-HCl product produced by microbiological fermentation, as well as the effects on body weight gain of combinations of glycine with lysine and methionine were investigated. The effectiveness on weight gain of methionine-hydroxy-analogue and methionine were compared. The possibility of improving the protein quality of amaranth was studied. Several feed additives (vitamin-B12 containing preparates, defluorized phosphate, Na-butyrate, by-products of the xilite production, ionized water, alginit) were also tested in broiler growth trials. The relationships of nutrition and body composition, as well as the digestive ability of pigeons were also studied. Complex studies were made on the physiological role, tolerance and adverse effects of the heavy metals (cadmium and aluminium) in broiler chickens and laying Japanese quails.
