mating records
max 2(week
check sperm quaility

- H.parasuis - glasser - serous fib
- Mycoplasma species . Fibrinous polyarthritis, pericarditis, pleuritis,peritonitis
- Other: E.coli, staph
Septic laminitis:
- Techono, splitting hoof, injury, foot rot, lameness
- Treat: AB, better florrs, biotin
104.Most frequent disturbances of sexual maturation in gilts. ’On farm’ diagnostic methods
and methods of prevention/therapy
Cyclic disturbance:
- Infantile ovary
- Juvenile ovary
- Juvenile ovary and uterine tract
Background:
- AI at first heat
- silent heat
- housing tech - too big groups, no moving, no free range
- feeding - low prot
- mycoestrogens fusarium
- Nutritional disorder
- Congenital tremors, salt poisoning in swine
congenital:
-Myoclonia congenita, shaking piglet, dacing piglets.
- Types:
A1- all, swine fever, cerebral hypoplasia and spinal cord, spinal cord hypomyelinogenesis.
A2- piglets, PCV1,PCV2, hypomyelinogenesis
A3- male piglets - death
A4- cross breeds, all
A5- Organophosphate exposure
B - unknown cause
Salt poisoning:
- Water supply
- try to drink, blind wandering, meningitis, pressing head, nose twitch
Treat - rehyd
- Congenital skin diseases in swine
- Epitheliogenesis imperfecta
- Hypoplasia pf skin, legs, flank, spine - Dermatosis vegetans
- Landrace, recessive, growing lesions - papules to papillomas, club feet, death - Pityriasis rosea:
- Landrace, sporadic, multiple piglets from same litter
- lower abdomen, chest, inne thigh, back,neck
- papules in a ring, scales, secondary infection
113.Phases of puerperium in sows
Puerperium - from farrowing to cycle. 28-40 days, 4-5w - for proper involution.
heat 4-5 days after weaning stops.
Lactation, myometrial contraction, pathogens.
- Non-infectious skin diseases in swine
Thrombocytopenia purpura:
- Suckling, type 2 hypersen, death suddently or weak, purple bruses.
- Transfer piglets to other sows, use other boar, cull sow.
Parakeratosis:
-Zinc def, 2-4m piglets, lower weight, macules on their stomach, papules with crusts, secondary infections.
Treat: change feed, treat secondary
Other:
- sunbruns, necrosis by chemicals
- food allergy
- injury, abscesses, photosensitivity
- Parenteral drug administration and sample collection techniques in swine
Parenteral:
- Iron def, salt posisoning
- Intraperitoneum.
Sample collection:
–feces, blood (ear,jugular, v.cava cranialis, urine, oral fluid, swabbing nose and tonsils.
- Oral drug administration in swine
Oral: colostrum, formula, milk powder.
With suckling reflex - baby bottle
No suckeling:
-Tube, lub
