Concentration of phytic acid in faeces of calves fed starter diets

Popis výsledku v původním jazyce

Ruminants utilize phytic acid well. Tilt! digestive system of young calves, however, is less developed than that of adult animals. The aim of our study was to decide whether phytic acid hydrolysis in the digestive tract of calves is complete or not. Thus, rectal samples of faeces were collected from 16 crossbred calves fed starter diets. Faeces of calves were sampled at the age of 1, 6 and 13 weeks. In starter concentrates and faeces the phytic acid content was determined by capillary isotachophoresis.Two commercial starters containing 9.17 and 12.80,, of phytic acid per kg of dry matter (37.6 and 50.1% of the total P) were offered ad libitum from the 4(th) day of life, Calves were weaned from milk, at the ae of 6 weeks. Phytic acid was determined in30 out of 37 faecal samples. Its concentration varied widely from I in, to 2.34 g per kg of dry matter. In some samples. the quantity of phytic acid Was insufficient for a precise determination. Phytic acid phosphorus represented 0 to 8.9
