Abstract :
The scope for using sunflower cake in ration formulation was tested in 6 horses employed for equine tour-ism. Three experimental diets providing the same amount of proteins and energy as the control diet were formulated using rising doses of sunflower cake (SD3: 0.3 kg; SD6: 0.6 kg and SD10: 1.0 kg). Digestibility evaluation using internal markers showed that rising sunflower cake doses reduced digestibility of nutrients. Statistical analysis using the diet effect demonstrated a significant reduction in dry matter (DM) (P=0.0006), ether extract (EE) (P=0.0001), crude fibre (CP) (P=0.0279), neutral detergent fiber (NDF) (P=0.0247) and acid detergent fiber (ADF) (P=0.0269) digestibility. Comparison of the two internal mark-ers acid insoluble ash (AIA) and acid detergent lignin (ADL) showed better digestibility values for all measures using ADL. Also glucose and urea showed statistical differences due to diet effect.
