INFLUENCE OF BUILDERS SAND ON THE TME OF LINSEED FOR POULTRY

The TME of whole or ground linseed with or without builder's sand was determined using precision-fed Single Comb White Leghorn roosters. Exc reta were collected 24 and 48 h after initial feeding. It was observed that the TME of ground linseed was higher than that of whole linseed. Feeding builder's sand resulted in greater TME (P < 0.05) compared to feeding the grain alone in either whole or ground form. However, ther e was no effect of grinding when builder's sand was fed. The data sugg est that dietary supplementation of poultry feed with builder's sand c an be alternative to grinding oil seeds. (C) 1998 Elsevier Science B.V .
