Preference By Sows For A Partially Enclosed Farrowing Crate, P. A. Phillips, D. Fraser, B. K. Thompson
Housing and Confinement of Farm Animals Collection
A preference testing apparatus was designed to give sows continuous access to three farrowing crates with different degrees of visual enclosure. A ‘fully enclosed' crate had solid black panels on the sides and top of the crate, a ‘solid-sided’ crate had the side panels only and an ‘open crate’ had no solid panels over the crate's tubular framework. The crates radiated from a central area sufficient for sows to enter or leave any crate freely. Video recording was used to determine sow position from 3 days before to 6 days after farrowing. The results indicated that younger sows (second or …

Discovery Of Selected Water Dispensers By Newborn Pigs, P. A. Phillips, D. Fraser
Housing and Confinement of Farm Animals Collection
Newborn pigs in 86 litters were offered drinking water from four types of dispenser to determine how quickly each design would be discovered. On average piglets discovered water within about 24 h from an exposed water surface (bowl or cup), whereas discovery time was delayed to more than 72 h with nipple or push-lever dispensers. A prototype dispenser with a wide bowl and continuous bubbling action reduced (P < 0.05) average discovery time to about 14 h.
