The effect of farrowing crate heat lamp location on sow and pig patterns of lying and pig survival.

Three experiments were conducted to study sow and pig behavior during the 1st 3 d after birth and pig survival during the 1st 2 wk after farrowing. In Exp. 1, 23 sows were housed in conventional farrowing crates that were divided into five sections: a .5- x 1.5-m front creep section and the remaining area divided into four sections, .75 x 1.05 m each. Air temperature was maintained at 19 degree...

Initial Test of a Farrowing Crate with Inward-Sloping Sides

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 w...

An ellipsoid farrowing crate: its ergonomical design and effects on pig productivity.

An ellipsoid farrowing crate was designed and compared to the conventional rectangular crate with regard to its effect on sows' production traits. The main features of this crate are its oval horizontal frame and bowed vertical bars. Thirty-two sows farrowed in each system. Those in the ellipsoid crates raised 318 pigs and those in the rectangular crates raised 304. Stillbirth rate was lower in...

Incidence of lameness and abrasions in piglets in identical farrowing pens with four different types of floor

BACKGROUND Lameness in piglets is a major animal welfare issue. Floor abrasiveness is a common cause of superficial injury in piglets in farrowing pens. The abrasion achieved may act as a gate for infections, which in turn may induce development of infectious arthritis. In this study, the influence of improvements of the floor quality and of increased ratios of straw in identical farrowing pens...

Floor temperature preference of sows at farrowing.

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 degrees C (+/-3.5), 29 degrees C (+/-1) and 35 degrees C (+/-1). Eighteen sow...
