The effect of duration of removal from grazing on body weight in sheep measured with an automated weighing system
Short-term body weight (BW) loss or gut-fill loss is a well-known issue in animal experimentation, which is usually controlled by consistent methodology between sets of weighings within experimental environments (Scott 2011; Whiteman et al., 1954). However, a review of literature provides few examples where the methodology states the length of time of feed and water restriction. Electronic identification (EID) and automated weighing crates enable weight data to have greater practical potential with the use of precision livestock farming techniques. Sheep handling, including weighing to relatively high precision, typically involves a number of hours of removal from food and water. There is little information on weight loss following removal from grazing over a short time period, but gut-fill can account for 12-23% of total BW (Hughes, 1976). The aim of this study was to quantify and characterise short term weight loss when sheep are removed from grazing.
