dc.description.abstractThe effect of microbial phytase in corn/soybean meal diets for broilers on performances and tibia characteristics were investigated. The trial was carried out on 200 Arbor Acres broilers of both sexes divided into four groups. The broilers were fed with complete mixtures with different levels of P (0.80 and 0.57% total P and 0.46 and 0.25% available P), with or without phytase. Reduction of the dietary total and available P levels for experimental broilers induced lower body mass and gain as well as higher fed conversion. However, by introduction phytase into diets negative effects of phosphorus reduction were, to some extent alleviated. Addition of phytase into diets decreased serum Ca and increased serum P. Reduction of the dietary P level had no significant effect on serum Ca, but had negative effects on serum P (p (lt) 0.01). The obtained results of bone analysis show that phytase was effective in increasing investigated parameters, but no significant differences were found among groups.en
dc.description.abstractIspitivan je uticaj mikrobijalne fitaze dodate smešama na bazi kukuruza i sojine sačme na proizvodne rezultate i čvrstinu tibije brojlera. Brojleri podeljeni u 4 grupe, su hranjeni obrocima sa različitim količinama P (0,80 i 0,57% ukupnog P i 0,46 i 0,25% iskoristivog P), bez ili sa dodatkom fitaze. Smanjivanje sadržaja P u smešama izazvalo je proporcionalno smanjivanje telesne mase, dnevnog prirasta i pogoršanje konverzije hrane, dok je dodatak fitaze doprineo poboljšanju vrednosti ispitivanih parametara. Dodatkom fitaze uočeno je smanjivanje koncentracije Ca, odnosno povećanje koncentracije P u krvi. Smanjivanje sadržaja P u smešama, nije imalo značajan uticaj na koncentraciju Ca, ali je značajno negativno uticalo na koncentraciju P u krvi (p (lt) 0,01). Dodatak fitaze u smeše sa smanjenom količinom P nije značajno uticao na koncentraciju Ca i P u krvi. Dodatak fitaze u smeše sa adekvatnim i smanjenim sadržajem P doprineo je povećanju čvrstine tibije, sadržaj pepela i Ca u tibiji. Dodatak fitaze nije imao posebno izražene efekte na sadržaj fosfora u tibiji.sr
