A 21-day experiment with day-old broilers was conducted in order to assess the effect of phytase supplementation to different cereals-soybean meal based diets on nitrogen, calcium, total and phytate phosphorus excretion and retention. Diets were formulated to contain 4 different cereals (maize, wheat, triticale and barley), 2 levels of dietary calcium (0.6 and 1.0%) and 3 levels of supplemental phytase (0, 500 and 1 000 PU/kg). Nutrient intake, excretion and retention were determined in the first three days of the 2nd and 3rd week of trial. The increasing phytase level resulted in reducing phytate phosphorus excretion and increasing its retention. Significant differences were obtained only in the 2nd week (excretion P < 0.024 and retention P < 0.044). Phytase supplementation significantly influenced total phosphorus excretion in the 3rd week (P < 0.048) and retention in the 2nd week (P < 0.015). The effects of 500 and 1 000 PU/kg were not statistically different from each other. No significant influence of phytase supplementation on nitrogen and calcium excretion and retention was observed.

Minerals And Trace Elements

29 laboratory animal diets from 5 manufacturers for rats, mice, rabbits, guineapigs, primates and dogs were analysed for calcium, total phosphorus, phytate phosphorus, magnesium, sodium, potassium, iron, zinc and copper. Variations between diets for the same species were found to be much larger than differences between means for different species. The analyses were compared with data in the manufacturers' catalogues. The best controlled element was potassium. Most deviations of other elements were distributed in a skewed fashion and quite serious differences between analytical and catalogue data were found. In general, deviations from the catalogue were less than variations between diets. It is recommended that catalogues should give ranges of composition rather than means.

The aim of this study was to investigate the effect of various calcium: total phosphorus (Ca:tP) ratios due to addition of microbial phytase and 1,25-dihydroxycholecalciferol [1,25-(OH)2D3] on the absorption levels of minerals. In a 42-day experiment repeated three times, 144 day-old male broiler chicks (ISA 220) were divided into six groups of eight chicks each. Diets containing two different (1:1 and 2:1) Ca levels were prepared. Groups 1, 2 and 3 received a diet of 1:1 Ca:tP ratio while Groups 4, 5 and 6 a diet of 1:2 Ca:tP ratio. These diets contained 1,25-(OH)2D3 and phytase in levels of 5 µg/kg and 600 FYT/kg, respectively. The faeces was collected to analyse the absorption of minerals. At the end of the study, the absorption levels of Ca, P, Zn, Mn and Cu were increased by the addition of phytase enzyme (p < 0.05). This effect was obvious in the 3rd week. On the other hand, in the 6th week only Ca and P absorption levels were influenced positively by the addition of phytase enzyme. The results proved the positive effect of phytase, an enzyme which is used for increasing the utilisation rate of phytate P, Ca and other minerals in broilers.
