Swine Notes • Scientific Name – Susscrofa • Other common names – swine, porcine • Monogastric Digestive System (single stomach) • Boar – male pig • Sow – mature female after she has given birth • Litter Size 8-12 • Gilt – immature female pig • Barrow – castrated male pig • Piglet – baby pig
Swine Notes • Gestation – 114-(118 days) – 3 months, 3 weeks, 3 days • Estrus Cycle – 21 days • Body Temperature – 102 degrees farenheit • Lactation – (21)-28 days • Farrowing – sow giving birth (parturition) • Average Daily Gain – approximately 2 lbs. per day. (gilts 1.7 – barrows 1.8+) • Feeder Pig – 50-60 lb pig ready to move into the finishing phase.
Swine Notes • Condition – measurement of body fat on breeding stock animals • Finish – measurement of body fat on market animals (typically measured between the 12th and 13th rib – called backfat) • Ideal backfat on a market hog is ½ inch • Porcine Stress Syndrome (PSS) – genetic condition that results in pigs that are very easily stressed sometimes even to the point of death • PSE – Pale, Soft and Exudative – condition of meat from swine that have been stressed shortly prior to slaughter.
Swine Notes • Paternal traits (father, sire, terminal) • Fast growth rate • Heavy muscling • Efficient Feed Conversion • Maternal traits • Large litter size (prolific) • Heavy milk production • Strong mothering instincts (docile)
