Floor Temperature Preference Of Sows At Farrowing, P. A. Phillips, D. Fraser, B. Pawluczuk
Floor Temperature Preference Of Sows At Farrowing, P. A. Phillips, D. Fraser, B. Pawluczuk
Housing and Confinement of Farm Animals Collection
A preference testing apparatus was used to provide sows with continuous access to three identical farrowing crates, each with a different floor temperature. The concrete floor under each crate contained copper pipe through which temperature-controlled water was circulated to achieve unoccupied floor temperatures of 22°C (± 3.5), 29°C (± 1) and 35°C (± 1). Eighteen sows were tested in the apparatus. Video recording was used to determine sow position from 7 days before farrowing (Days ‒7 to ‒1) to 14 days after (Days 1 to 14). On Days ‒7 to ‒1, sows showed no significant preference among the three temperatures …
Sow Preference For Types Of Flooring In Farrowing Crates, P. A. Phillips, D. Fraser, B. K. Thompson
Sow Preference For Types Of Flooring In Farrowing Crates, P. A. Phillips, D. Fraser, B. K. Thompson
Housing and Confinement of Farm Animals Collection
A preference-testing apparatus was used to provide sows with continuous access to three identical farrowing crates, each with a different type of flooring. The crates radiated from a central hub area sufficiently large for sows to enter or leave any crate freely. In exp. 1, nine sows from a concrete-floored gestation room were offered crates over concrete, plastic-coated rod, and galvanized metal rod. In exp. 2, sows were pre-exposed for a period of 1 wk to one of the three floors before entry into the preference testing apparatus. Video recording was used to determine sow position from 3 d before …
Sow Preference For Farrowing-Crate Width, P. A. Phillips, David Fraser, B. K. Thompson
Sow Preference For Farrowing-Crate Width, P. A. Phillips, David Fraser, B. K. Thompson
Housing and Confinement of Farm Animals Collection
A preference-testing apparatus was designed to provide sows with continuous access to three farrowing crates of different widths. The crates radiated from a central hub area sufficiently large for sows to enter or leave any crate freely. In exp. 1, nine sows were offered crates of 450-, 600- and 750-mm width at standing height. In exp. 2, 12 sows were offered widths of 450, 750 and 1200 mm, the largest being of sufficient width for the sow to turn around. Video recording was used to determine sow position from 3 d before to 6 d after farrowing. In exp. 1, …
