Processing impacting pigs

Why do we process ingredients and diets for pigs

Improve palatability

To reduce detrimental substances like bacteria, toxins, ANF

Improve digestibility

Prevent spillage and/or selection

Reach a proper balance in nutrients

Support function and health of the gastrointestinal tract

Logistic benefits

Meal or pellet

Meal vs poor quality pellet vs screened pellet

pellet diameter of creep feed

Particle Size Distribution

Dry sieving

• weigh sample

• Sieve sample by shaking

• Weighing per sieve

• Weight per sieve as % of total

Wet sieve

• Weigh sample

• Soak sample

• Sieve sample (water + shaking)

• Drying per siev

• Weighing per sieve

  • Weight per sieve as % of total

Effect on particle size on fecal digestibility of energy and protein

the smaller the better

particle size and animal health

ef

effect of particle size on stomach health

compositoin

generally, factors increasing stomach content firmness are therefore expected to be able to prevent gastric lesions

more energy in the diet for GF pigs

A preference for processed ingredints in meal diets

processing of ingredients: oilseed mealsS

processing of the RSM

Processing of the diets

Apparent ileal digestibility - lysine

rate of starch digestion in the small intestine of pigs
