Bunk Attendance Of Feedlot Cattle Monitored With Radio Frequency Technology, D. J. Gibb, T. A. Mcalllister, C. Huisma, R. D. Wiedmeier
Management and Monitoring of Farm Animals Collection
Bunk attendance of 72 feedlot cattle (412 ± 23.6 kg) was monitored for 86 d using radio frequency technology. Late morning and late afternoon were confirmed as primary ad libitum feeding periods. The system detected differences (P < 0.005) in feeding behaviour in response to level of feeding and frequency of meals.

Initial Test Of A Farrowing Crate With Inward-Sloping Sides, D. Fraser, P. A. Phillips, B. K. Thompson
Housing and Confinement of Farm Animals Collection
A farrowing crate was designed with sides spaced well apart (1150 mm) at the sow's standing height but angled inward near the floor to restrict the sow's lying area and to prevent the sow from dropping suddenly onto one side. Survival and body-weight data were collected for 20 farrowings in the prototype crate and for 18-20 farrowings in each of 3 other crate types. No significant differences were found in stillbirth rate, other deaths to 14 days, or average piglet weight gains, but gains were somewhat more variable in one of the conventional designs which interfered with the piglets' access …
Preference Tests Of Ramp Designs For Young Pigs, P. A. Phillips, B. K. Thompson, D. Fraser
Preference Tests Of Ramp Designs For Young Pigs, P. A. Phillips, B. K. Thompson, D. Fraser
Housing and Confinement of Farm Animals Collection
Preference experiments were used to identify features of ramp design that influence the voluntary use of ramps by young pigs. In seven experiments, groups of pigs, aged 7-8 wk, were given free access to four different ramps simultaneously. The animals' behavior was monitored to identify the amount of time spent on the ramps and the number of pigs that failed to use specific designs. Slope, in the range of 20-32° from the horizontal, had a major influence on the pigs' behavior, with the shallower slopes attracting more use than steep ones. Pigs preferred ramps with angle-iron cleats (cross-laid on the …
