中文摘要

The objective of the study was to determine the effect of feeding different levels of rice hull powder on the behavior of sows. Sixteen LYD crossbred sows of average body weight 200 kg were randomly allocated into 4 treatments. The diet formulation was 100% normal diet as Treatment 1, 85% normal diet: 15% rice hull powder as Treatment 2, 70% normal diet: 30% rice hull powder as Treatment 3 and 55% normal diet: 45% rice hull powder as Treatment 4. Feed was provided ad libitum while feed residue was collected daily at 18:00. During the adaptation period, 24 hours behavior observation was conducted 4 times continuously, with an average 3-4 days once. The results showed that feed intake increased to about 3 kg per day when feeds mixed with rice hull. If the total nutrient intake (or feed intake) in Treatment 2, 3 and 4 was calculated, it would be 2.5, 2.1 and 1.65 kg, respectively. That is, if the sow’s diet was mixed with about 30% rice hull, the sow still can get about 2 kg of concentration feeds. Sows fed high rice hull diet showed lower vacuum chewing activity and dog sitting behavior.
