Summary:
Hydrolysis of food components in animal intestinal tracts may be advanced by adding suitable microbial enzymes. Besides usual food hydrolysis, the addition of microbial enzymes showed also other improvements: degradation of the indigestible parts of meal (e.g. use of less valuable feed), better organoleptic food characteristics, favorable influence on fecal consistency and ecological conditions in inhabitancies. The efficacy of the multienzymatic preparation added to feed loas investigated in chicks fattening during 50 days and in fattening of pigs from 9.5 kg until they reached 25 kg weight. The chicks, that consumed niulticnzyniatic preparation showed the weight gain increase in the range of 0.75-5.33 % and improved feed conversion between 1.92 and 8.34 %. In comparison with control group without enzyme addition, 1.16 % lower weight gain was delected after 28 days of pigs nutrition. However, the feed consumption decreased by 9.83 % and feed conversion increased by 8.46 %. The presented results confirmed the economic justifiability of meal production using the multienzymatic preparation in feed.
