There is increased interest in using sugar beet pulp (SBP) products as forage replacers in equine diets. Previous work (Hyslop et al 1998) has indicated that SBP products may suppress voluntary feed intake (VFI) in ponies when they are the major fibre source at between 550-700 g/kg total diet dry matter (DM). This study examines VFI and apparent digestibility in vivo where soaked unmolassed sugar beet pulp (USBP) was offered as a partial forage replacement to ponies receiving ad libitum grass hay.
Four mature Welsh-cross pony geldings (280 kg LW s.e. 6.6) were individually housed and offered 0.86 kg/d of micronised barley (MB) and given ad libitum access to grass hay (HAY). In addition, ponies were offered either 0, 1, 2, or 3 kg/d USBP (U0, U1, U2 and U3 respectively) according to a 4 x 4 latin square changeover experimental design.
