Effect of feeding whole wheat or whole oat grain on particle size and whole grains in faeces from lamb

Nørgaard, Peder; Bostad, Elise

Abstract

The aim of the present experiment was to compare faeces characteristics in lamb fed either whole wheat (W) or whole oat grain (O) ad libitum. Nineteen Shropshire lamb were splitted up into 2 equal groups from weaning at 20 kg to slaughter at 45 kg. They were fed whole grains ad libitum plus 100 g protein concentrates per lamb twice daily. The average daily intake of W and O one week before slaughter was 1100 and 990 g, respectively. At that time faeces were collected twice daily during two days, washed in bags with a pore size of 10 µm, dried and sieved into five sieving fractions plus whole grains before canning. Particle length (PL) and width (PW) were measured by image analysis. Data were analysed by proc mixed in SAS 8.2. Proportion of particle dry matter (PM) in faeces dry matter, proportion of whole grains in PM and particles retained in the bottom bowl were affected by grain type (P<0.05). The arithmetic mean PW, the most frequent PW, the median PW and the 95 % PW values in PM excl. whole grains were affected by grain type (P<0.05). O and W grains accounted in average for nine and sixteen percentage of faeces PM, respectively. In conclusion, the ability of the reticulo-rumen to retain whole grain appears to be related to the intake of physical effective fibre
