▪ Shortage of water; volume and quality

▪ Heat stress

▪ Stale, wet feed

▪ Mycotoxins and molds

▪ Too low protein

▪ Health status

▪ Stocking density

Causes of decreased feed consumption in lactation

Maintenance LactationGrowth Reproduction

Nutrient partitioning 1st parity sows

▪ Clotting mechanism activates

▪ Increased blood flow

▪ Increased capillary permeability

▪ Enhanced influx of phagocytic cells

• Neutrophils arrive in 30–60 minutes

• Macrophages and lymphocytes 5–6 hours

Impact of inflammatory mediators on claw horn production

▪ Addition of TNF-α resulted in inhibition of keratinocyte

proliferation vs. control over a period of 6d

▪ Inhibition was less pronounced for IL-1α
