Lameness in breeding swine has a large negative economic impact and is a welfare concern. Pain-related behaviour, such as postural changes, may be used to evaluate the presence and severity of pain in animals. The objective of this work was to determine the effects of flunixin meglumine (FM) and meloxicam (M) on postural changes in lame sows. Lameness was induced in 24 mature sows (Sus scrofa) using a chemical synovitis model. Three treatments were compared: FM (2.2 mg kg; n = 24, intramuscular… 

Sow behavioral responses to transient, chemically induced synovitis lameness

Stable, lying and drinking frequencies seem to be promising sow behavioral tools when transitioning from sound to lame states, and the induced lame foot had no observed effect on lying side preference.

Use of Meloxicam or Ketoprofen for Piglet Pain Control Following Surgical Castration

The findings indicate that the use of these NSAIDs were ineffective at alleviating castration-associated pain in piglets, and the Piglet Grimace Scale (PGS) does have utility as a pain assessment tool in neonatal pigs.

Lameness: a principle problem to sow longevity in breeding herds

This review shows that additional research is still needed, especially studies to accurately evaluate lameness lesions, examine nutrient requirements for optimum foot health, investigate genetic effects on feet and leg conformation, clearly define the supplemental vitamin or / and mineral levels and duration for usage.

A Review of Pain Assessment in Pigs

This narrative review identifies the sources of pain in pigs, discusses the various assessment measures currently available, and proposes directions for future investigation.

Flooring preference and behavior in sound and lame sows

Sows appear to prefer the Mat within 24 h following lameness induction, and lying lateral is likely a more comfortable position than standing or lying sternal in these lame sows.

Identifying physiological measures of lifetime welfare status in pigs: exploring the usefulness of haptoglobin, C- reactive protein and hair cortisol sampled at the time of slaughter

The results suggest that hair cortisol measured at slaughter could provide insight into the welfare status of pigs during their lifetime, and Hp may be a useful indicator of tail lesions in pigs.
