High-tech camera helps protect sows and piglets
Agricultural Research Service (ARS) scientists and collaborators are using 3-D imaging to protect newborn piglets by monitoring adult female pigs' behavior.
SowBridge Educational Series continues to provide quality programming
SowBridge is designed to improve the understanding and application of various tools and techniques involved in daily care of the breeding herd and piglets.
Growth rate and lameness in replacement gilts
Does a high growth rate really increase the risk of osteochondrosis and lameness?
Temporary nurse sows: How to increase the number of teats on batch farrowing systems
The article explains how to manage nurse sows in 3-week batch farrowing systems with a practical example.
Energy and lysine requirements of sows during transition and lactation
The SID Lys:ME ratio during lactation depends on a milk yield and the body weight of the sow.
The ideal farrowing facilities (2/2): feeding and environmental control systems
This time, Joan Wennberg discusses the different feeding and environmental control systems in the farrowing house with Heraclio Corchón and Javier Lorente
Frequency and time of gestation feeding and their subsequent effects on farrowing performance
Effect of feeding time and frequency during gestation does not affect farrowing performance.
Different colours on sow cards
Sometimes, when working on the farm, we have to get up close to the sow to check its card in order to know its productive cycle. Or, whilst carrying piglets to be fostered, we ask ourselves, will that sow be a second parity one?
Different feeding levels during wean-to-estrus and first week of gestation of sows
High feeding level during the wean-to-oestrus may increase farrowing rate but also may increase stillborn rate and reduce piglet birth weight.
Pathological evaluation of claw lesions in culled sows from a Greek herd
Sow laminitis may frequently occur, causing production of low quality hoof horn.
Arginine and amino acids supplementation in gestating gilts
Arginine and other amino supplementation in gestating gilts improve farrowing and litter performance in low prolificity sows (≤14 total piglets born).
The ideal sow herd structure does not have a triangular shape any more
Traditional culling policies have a threshold number of farrowings after which sows are culled —after weaning. But, what would happen if this policy were to be modified to actually consider the performance of each sow?
Walking through sow housing and tools available
"Walking Through Sow Housing and Tools Available" - PORK Academy - Dr. Tim Safranski, University of Missouri, from the 2017 World Pork Expo, June 7 - 9, 2017, Des Moines, IA, USA.
How efficient are the current hyper-prolific lactating sows? (2/2)
In the previous paper, the effects of nutrient restriction and consequent catabolism during lactation on sow reproduction yield have been addressed. In the present paper, the efficiency of sows in using energy from feed and body mass is considered.
Introduction of replacement gilts to PRRS-positive sow herds
A study was performed including 69 PRRS-positive sow herds with the aim of comparing the use of PRRSV MLV and quarantine facilities with the PRRSV status of replacement gilts at first insemination.
