The effect of age of pre-ruminant calves on starch digestibility

Popis výsledku v původním jazyce

Apparent starch digestibility (ASD) was studied in an experiment with five Czech red spotted breed male calves in the age of 9 to 91 days. Animals were fed on a milk replacer containing 5 % of wheat starch. Digestibility was determined in 23 three-day balance periods using the chromic oxide indicator method. The average estimated value of ASD was 0.934 ? 0.00536. Starch digestibility changed highly significantly (P<0.01) with age of calves. The dependence of determined values (Y) on age in days (X) wasexpressed by the 2nd degree parabola equation with a maximum on Day 54. The most marked increase was observed in the first weeks of the experiment, from Day 9 to Day 28 0.0064 per day (P<0.05). It is of interest that even in very young animals starch wasmore digestible than it was expected.
