| Description
| - Zjišťovali jsme dostupnost fytátového fosforu (P) u nosnic krmených dietou založenou na kukuřici a sojové mouce. Stravitelnost fytátového P byla vyšší u nosnic věku 47 týdnů (53%) než u nosnic věku 20 týdnů (24%). Exkrementy starších nosnic obsahovaly významně méně P fytátu (3,1 mg/g sušiny) než exkrementy mladších nosnic (4,5 mg/g sušiny). Specifická aktivita fytasy (na 1 g) v žaludku, sliznici střeva a slepých střevech byla vyšší u starších než u mladších nosnic. Vysoká celková fytasová aktivita byla zjištěna v slepých střevech mladších (347 mikromol/h) i starších (632 mikromol/h) nosnic. Nízká byla v žaludku (47 a 102 mikromol/h) a střední v tenkém střevu (226 a 264 mikromol/h). (cs)
- The availability of phytate phosphorus (P) was determined in hens fed a maize-soybean meal diet. The availability of phytate P was higher in 47–wk–old hens (53%) than in 20–wk–old hens (24%). The excreta of older hens contained significantly less phytate P (3.1 mg/g DM) than that of younger hens (4.5 mg/g DM). Specific activity (per g) in the stomach, intestinal mucosa and caeca was higher in 47-wk-old hens than in 20-wk-old hens. A relatively high total phytase activity was found in the caeca of both young (347 micromol/h) and old (632 micromol/h) hens compared to that in other digestive segments, with little activity in the stomach (47 and 102 micromol/h, respectively), and intermediate in the small intestine (226 and 264 micromol/h, respectively).
