A comparison of sow and piglet behaviour and productivity in the UMB farrowing pen compared to conventional farrowing crates Progress Report

In recent years there has been a growing interest in the standard of farrowing accommodation for commercial sows in Australia and in many countries around the world. Conventional farrowing crates are used extensively in the pork industry due to the general belief that piglet mortality and morbidity due to accidental crushing by the sow is reduced (Weary et al. 1996). However, restraining the so...

Productivity and Behavior of Sows in Level vs. Sloped Farrowing Pens and Crates

Forty crossbred sows were used in 10 blocks to determine the effects of farrowing pen type and degree of slope on sow-litter performance and behavior. The two pen types were a farrowing pen (2.15 m sow area plus 2.15 x 3 5 m creep area) and a farrowing crate (1.5 x 2.15 m). The two slopes evaluated were level (0% slope) and 8% slope. To collect behavioral data, a sample of litters was videotape...

Effects of Creep Heat Type and Location on Its Usage by Piglets in Farrowing Crates

Comparative tests were conducted in an environment-controlled farrowing room (21 ° C, 70 ° F) to determine the choice of mat heat vs. lamp heat by piglets in farrowing crates. Two widened farrowing crates (2.40 × 2.13 m, 8 × 7 ft.) were used, each equipped with two double-size heat mats (0.6 × 1.2 m or 2 × 4 ft, 120 W capacity each). One mat was powered to provide the localized heat, while the ...

Confinement of lactating sows in crates for 4 days after farrowing reduces piglet mortality.

To reduce mortality among suckling piglets, lactating sows are traditionally housed in farrowing crates. Alternatively, lactating sows can be housed in farrowing pens where the sow is loose to ensure more behavioural freedom and consequently a better welfare for the sow, although under commercial conditions, farrowing pens have been associated with increased piglet mortality. Most suckling pigl...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
