Building a handling course to document sow locomotion when sows are afflicted with different naturally occurring lameness
Sow lameness is a major production disease affecting welfare and profitability. In 2014, Karriker and colleagues created a comprehensive swine lameness diagnostic manual which incorporated several diagnostic tools and pre- and post-mortem assessments.
Evaluating the effects of mitigation strategies on piglet welfare and future productivity after transport during different seasons
As consumer concern for swine welfare, husbandry methods, and antibiotic use in animal agriculture increase, so will the need for U.S. pork producers to demonstrate that current production practices...
Effect of short term high tryptophan diet fed to sows on subsequent piglet behavior
Laws have been passed in several states requiring group housing for pregnant sows. However, the predominant problem with group housing sows is aggression. Different approaches, such as changing group...
Using conveyor belt to load and unload pigs to promote self-movement of piglets
Pigs are not accustomed to climbing sloped ramps. However, sloped ramps are impossible to avoid in regular management and handling practices due to design of the physical facilities at finishing...
Evaluating the welfare of piglets after weaning and transport during heat stress
Weaning is a complex stressor associated with social, environmental and metabolic stress in pigs, that can be compounded by the negative effects of transport and thermal stress. To combat these...
Optimizing on-farm management of non-infectious sow lameness during the farrowing and lactation period
