Evaluation of Sow Caliper for body condition measurement of gestating sows
Journal of Swine Health and Production, 2021 Objectives: To evaluate correlation between Sow Caliper measurement and backfat depth (BFD), and to determine the ideal caliper measurement that predicts optimal BFD prefarrowing to support performance of lactating sows. Materials and methods: Multiparous sows (n = 928, Parity 1-9) were group housed in pens from day 35 to 109 of gestation.

Development of a Precision Feeding System with Hierarchical Control for Gestation Units Using Stalls
Applied Sciences, 2023 To obtain good productive performance, sows have different nutrition requirements at different gestation periods. However, in gestation stalls, conventional feeders have large relative errors, management is difficult because of the large numbers of sows,

Results of 15 Years of Precision Feeding of Hyper Prolific Gestating Sows
Animals, 2021 The increase in prolificacy at weaning is less than that at farrowing due to increased loss of piglets. As a result, farmers focus more on solutions that can prevent difficult parturition or a decrease in milk production.

Fecal Estrone Sulfate Profile in Sows during Gestation.
Journal of Veterinary Medical Science, 1999 The aim of this study was to establish radioimmunoassay (RIA) for fecal estrone sulfate (E1S) and to elucidate changes in fecal E1S during pregnancy in the sow. Fecal E1S was extracted on a commercially available solid phase column, and the E1S fraction obtained was subjected to RIA. The sensitivity of the RIA was 8.5 pg/tube.

Group Space Allowance Has Little Effect on Sow Health, Productivity, or Welfare in a Free-Access Stall System [PDF]
, 2014 Free-access stalls allow sows to choose the protection of a stall or use of a shared group space. This study investigated the effect of group space width, 0.91 (SS), 2.13 (IS), and 3.05 (LS) m, on the health, production, behavior, and welfare of ...
