Large Animal Medicine II Final Exam Flashcards
Swine karyotype is
2n= 38
Now, daily growth of grower finisher pigs went up to
950-1200 g/day
In swine medicine, method to optimize health, welfare, and production in a population of animals through the systematic analysis of relevant data and through regular objective observations such that informed timely decisions are made to improve herd management over time.
Herd Health Management approach (HHM)
Herd health management is based mainly on
Prevention. Based on identification of risk factors for disease
Sows produce colostrum containing that has this to enhance uptake of intact immunoglobulins
anti-trypsin factor
T/F stomach pH in piglets is close to neutral making young piglets susceptible for enteral infections
True
In piglets 2-10 days old, diarrhea, low mortality. Multifocal suppurative and erosive colitis. Confirmed by ELISA of fresh feces. Tx with virginiamycin and tylosin in piglets

Clostridium difficile associated enterotoxemia
Causes enterotoxemia in piglets 2-10 days old. Minimal gross lesions but multifocal suppurative enteritis with large Gram + rods. Isolation and genotyping of a beta 2 toxin is warranted. Tx with bacitracin in sows and salinomycin in piglets. Vaccination is available
Clostridium perfringins type A associated enterotoxemia
Piglets 1 day to 2-4 weeks old postweaning. Virulence includes fimbria, enterotoxins, endotoxins, and capsules. Dams are carriers. Poor sanitiation and chilling play role. Severity is related to dose ingested and immunity from colostrum. Can survive in contaminated buildings and keep infecting. Shivering, watery diarrhea, and vomiting occur. Dx with culture and PCR. Tx with antimicrobials. Practice good sanitation and vaccination twice before farrowing
E. coli (Enteric colibacilloisis)
Acute and fatal entertoxemia of recently weaned pigs. Characterized by edema, sudden death, and neuro signs such as paddlinging and squealing.
Edema disease (colibacilosis)
Several serotypes of E. coli
Usually in confinement raised 1-3 weeks old nursing piglets. When unexposed pigs are placed in contaminated area. Carrier sows are the source. Signs are yellow pasty diarrhea, dehydration, rough hair coat. No response to antimicrobials. Tx with Toltrazuril

Coccidiosis (Isospora suis)
Usually in piglets 1-6 weeks old. Diarrhea, vomiting, non fatal. Enteritis with moderate villous atrophy. Dx with ELISA or FAT of feces.
Rotaviral enteritis
All age groups susceptible but mostly piglets <4 weeks old. Acute form with high mortalitiy and endemic form is less serious. Dx with FAT or IHC on intestine of acutuely affected pigs or PCR of feces.
Transmissible gastroenteritis
Most important strep infection in pigs. Usually nursing or recently weaned piglets. Septicemia, meningitis, polyarthritis, bronchopneumonia. Zoonotic. Isolated from nasal cavity and tonsils of pigs. Eliminate stress and overcrowding. Vaccinate sows. Tx with antibiotics
Streptococcus suis
Syndrome usually within 3 days of farrowing and causes inadequate milk production. Hypogalactia, weakness, anorexia, sternal recumbancy, resistent to allow nursing. Cause unknown. Resolved by proper sanitiation, exercise, and nutrition
Hypogalactia or Mastitis, Metritis, Agalactia (MMA)
In pigs mastitis is most commonly
Enviornmental
Dermatitis usually seen in 4-12 week old piglets. Reddened raised ring shaped lesions usually on ventral abdomen. Dx with exam and no treatment required. Non pruritic and no affect on pigs. Cause unknown

Pityriasis rosea
Abnormalitiy of neonatal pigs with lateral extension of the hind legs with inability to adduct legs. Myovibrillar hypoplasia related to delayed development. Genetic disposition, slippery floors, and PSS are causes. Tx by tying legs together
Splay leg
Inheritied condition. Abscence of discrete areas of skin. Hydroureter and hydronephrosis also seen with condition. Fetuses may be aborted or born.

Epitheliogenesis imperfecta
Treatment for Erysipelas
Penicillin or antiserum
Caused by staphylococcus hyicus. Pigs less than 8 weeks old. Brownish spots with serum or exudate. No pruritis. Isolate affected pigs, and spray pigs with 10% bleach, chlorohexadine, Durvet or dilute iodine
Greasy pig disease (Exudative Epidermitis)
Caused by Brachyspira hyodysenteriae. Mucohemorrhagic diarrhea with marked inflammation limited to the large intestine. Persists in rodents and water. Eradication program in place and replace herds.
Swine dysentery and spirochaetal colitis
Results in septicemia, enterocolitis, and asymotimatic swine. Disease is less common but occurs mostly in weaned pigs. Often appears during stressful events. Tx with carbodox, gentamycin, neomycin, and others
Salmonellosis
Causes septicaemic salmonellosis in swine. Acute onset of outbreak with acute death loss in a group of apparently thrifty pigs
Salmonella chorerasuis
