ADSC 2010 Lecture 37Outline of Last Lecture I. Management of BreedingII. Management During GestationIII. Management at FarrowingIV. Management During LactationV. Care of Baby PigsOutline of Current Lecture I. Selling to Grower/FinisherII. Farrow-to-FinishIII. Multiplier/PurebredIV. Swine DiseasesA. Bacterial/ViralB. NutritionalCurrent Lecture: I. Selling to Grower/Finisher- Not labor intensive- End of nursery phase (40-60 lbs.) to slaughter (250-290 lbs.)- Requires less physical management- Hogs confined and on full-feed (ad libitum)- Walk through, listen for coughing- High feed requirements- Normally divided into phases- Grower: 50-100 lbs. or 3 months old- Finisher: 100-260 lbs. or 6 months old.- Protein: 16% (grower)  14% (finisher)II. Farrow-to-Finish: most common in US- Encompasses all aspects of production- End product: slaughter hog- Don’t share profits- High labor / management requirements- High feed requirementsIII. Multiplier/Purebred- Little purebred in current industry, mostly composite “lines”- Similar to farrow-to-finish phase as far as feed requirements- End product: breeding stock (boars/gilts)- Also produce some slaughter hogs (cull gilts and barrows)- Greater requirement for skilled management than any other phase/segment- Higher investment due to cost of superior geneticsIV. Swine DiseasesA. Bacterial/Viral1. Pseudorabies (mad-itch) – viral – Herpes virus Young pigs High temperature, convulsion, paralysis in pigs Abortion, infertility, weak pigs in adults Vaccinate sows prior to breeding season2. Swine Dysentery (bloody scours) – bacterial Inflammation of intestine (lining of colon) Bloody diarrhea / black stool 8-14 week old pigs (increase in death loss) Spread with contact of contaminated feces Treat with antibiotics and sulfa drugs in the water3. Transmissible Gastroenteritis (TGE) – Viral  Scouring (yellow) / vomiting Increased mortality in young pigs (7-10 days old Treatment: isolate sows, make sure that pigs get colostrum, sanitation, vaccinate sows4. Atrophic Rhinitis – Bacterial Respiratory: destruction of cilia and turbinate bones in the nose Persistent sneezing/bleeding (death generally due to pneumonia) Treatment: antibiotics and sulfa drugs in the feed or waterB. Nutritional1. Anemia Iron deficiency Weak pigs, problems with temperature regulation Inject IM at 3-4 days2. Porcine Epidemic Diarrhea Virus (PEDV) – Viral England, China, Korea, Japan, US Similar to TGE, not zoonotic Extreme death loss Extremely contagious: transmitted fecal/oral route Primarily a problem in pigs: >90% mortality Dehydration extremes, huge outbreak in
