Scientific Name – Sus scrofa 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 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. 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. Paternal Fast growth rate Heavy muscling Efficient Feed Conversion Maternal traits (father, sire, terminal) traits Large litter size (prolific) Heavy milk production Strong mothering instincts (docile) Diagrams Parts (27) Bones (24) Wholesale Cuts (5) Ear Notching (10) How would piglets behave on a sow with lactation failure?
