| Popis: | In this study, we used the Manchurian golden breed of quails. We assessed the efficacy of the food additives of the phytase from Obesumbacterium proteus encapsulated in the recombinant Yarrowia lipolytica yeast, which was supplied at a concentration of 500 phytase activity units per kg of the feed. One hundred fifty one-day-old quails were distributed into six treatment groups. The results showed that adding the O. proteus encapsulated phytase to the quails’ diets improved live weight, body weight gain, and feed conversion compared to those in the control groups and the groups using a commercial phytase from Aspergillus ficuum. The results obtained during the experiments indicate a high degree of assimilation of phytate-containing feeds if the encapsulated phytase was fed by the quails compared to that in the other groups. We can conclude that the class D encapsulated phytase is an expedient additive to the diets possessing better kinetic features compared to the PhyA and PhyC classes phytases when it acts inside the quail’s chyme. |
