Deterioration of foods for animals considers variation from the normal quality, considering the changes of organoleptic traits, nutritive values and for hygienic accuracy of food. The bad effects of adulterated food are shown in achieving worse production results in animals, incidence of metabolism disorder and illness, as well as losing animal life. Besides the bad influence of adulterated food, on the less utilization of nutritions ingredients it has bad effects on the fattening as well, antinutritions ingredients: phytate, oxalate, some structure carbohydrates, pentosan, etc. Considering all these facts, the aim of our examinations was that with addition of different additives into the diets for animals, we have influence on improving hygienic accuracy of food as well as improving utilization of feeding substance from food. The examination were done during the experiments of feeding poultry: laying hens, turkeys, chickens. Mineral adsorbents (zeolites) and enzymes (phytasa) were used as additives. The main results of examinations presents following: laying hens had better carryning capacity and better eggs quality, with addition of 0,3 or 0,5% zeolites into diets; turkeys with 0,2% zeolites gained better body weights and had better results in surviving; chickens also had better production performances with addition of 0,3% zeolites into the diets. Addition of 0,1% enzymes of phytase into the diets for fattening chickens had well influence to all observed traits. We conclude, that addition of examined additives into the diets for animals is totally warrantable and the reason for that are the results of our examinations.
