Extract

There is increasing evidence that hunger and frustration of feeding motivation are potential sources of stress for pigs on restricted food levels such as tethered, pregnant sows. However, it is not clear what factor(s) of feeding regimes are critical in this respect. It has been suggested that the hunger of pigs on restricted food allowances may result in part from the use of concentrated foods lacking dietary bulk. This paper reports on 2 experiments conducted to examine the effect of straw as dietary bulk on hunger as measured by operant response rate.
