The mortality, a great problem <strong>of</strong> this hybrid on practice in Bulgaria, wasdecrease by 2.50%.2. The meat quality was no influenced by the additive.GENARAL CONCLUSIONSUsing the animal nutritional additives is on the focus <strong>of</strong> many scientists. We have tohave not only a sound knowledge <strong>of</strong> fundamental nutrition <strong>and</strong> background but also farmconditions on practice <strong>and</strong> good underst<strong>and</strong>ing <strong>of</strong> statistics. Institute <strong>of</strong> Animal Sciencein Kostinbrod, Bulgaria, with its working group on nutrition <strong>and</strong> feed technology has agreat experience on using additives in animal nutrition. So <strong>of</strong>ten our trial results areinconclusively. They sometimes could not be published under the scrutiny <strong>of</strong> scientificjournals. But our experience up to now is significant. We have a gained database <strong>of</strong> moreBulgarian <strong>and</strong> not Bulgarian additives by different type <strong>and</strong> kind <strong>of</strong> animals. It couldallow us to go on our experimental work with sure benefit influence for both animalscience <strong>and</strong> husb<strong>and</strong>ry to optimizing animal nutrition, the health <strong>of</strong> animal, level <strong>of</strong>production, reproductive capacity <strong>and</strong> quality <strong>of</strong> products from animal origin.REFERENCES1.
