FAM II Lecture 44

What is being shown?

Can increase or decrease susceptibility to infection; coronavirus, salmonella, clostridium, general gut integrity

Surveillance; geographic information systems (GIS); test prior to movement; stop movement orders/embargo

Fenbendazole; Hygromycin B

Local + regional challenges; economic impact of disease; desired level of protection; impact of vxn on production

Robenidine; salinomycin; semduramycin; sulfadimethoxine; sulfadimeth + Orm

Watch for early signs to prevent spread; get dx: report unusual signs esp. w/ ^ mortality; submit samples to state lab

Critical part of infection control + prevention; 1: healthy young, 2: healthy old, 3: quarantined; 4: sick

Administered individually; needs adjuvant; less immunogenic; less protective; requires booster

Type of production - layers, breeders, meat birds, chickens vs turkeys; maternal Ab decay; age to market

Negative production effects short term; disease potential; roll-over; reversion to virulence

Amprolium; bambermycin; decoquinate; diclazuril; halofuginone; lasalocid; monensin; narasin; nicarbazin; zolene

Vaccine interactions (timing of vaccinations)

Intense _ produces uniformity in phenotype esp. in relation to desirable production char., but reduces survivability

Amprolium; bambermycin; diclazuril; halofuginone; lasalocid; monensin; sulfasimethoxine; sulfadimeth + Orm; zolene

Erythromycin

Fenbendazole; piperazine

Voluntary state/federal cooperative testing + certification program; commercial poultry (ckns, tkys, waterfowl)

Bacitracin; Ceftiofur; Erythromycin; Gentamicin; Neomycin; Pen G; Sulfas; tetracyclines; Tylosin; Virginiamycin

Be careful about obtaining birds from neighbors; quarantine new birds (40-45d); know warning signs of infectious dz

Don't haul disease around; always clean vehicles, crates, equip.; don't borrow disease from neighbor; avoid tool sharing

Bacitracin; Ceftiofur; Erythromycin; Gentamicin; Lincomycin; Neomycin; Pen G; Spectinomycin; Sulfas; Tetracyclines

Mass administration; better immune response; better protection

Breeding flocks, hatching eggs, hatcheries, chicks, poults, poultry dealers, exhibition birds, small/backyard flocks

Limited production effects; no disease potential; no roll-over; no chance for reversion

Enzyme linked immunosorbent Assay (ELISA) - antibody levels (titers)

Decreases disease resistance

Permethrin; Tetrachlorvinphos

Gamebirds; objective: testing to ensure freedom from specific dz: pullorum, fowl typhoid, salmonella enteriditis

Amprolium

Give birds + meds a chance; encourage to drink, eat, move; ^ temp + ventilation rate; FARAD

Tylosin; Virginiamycin

Fenbendazole; hygromycin B; piperazine

Only use approved meds - all poultry considered food animals; choose meds based on effectiveness; admin precisely

Test, euthanize + dispose; test + control; ring vaccination

Specific dz: mycoplasmosis (MG, MS, MM), avian influenza (H5/H7); certified disease free + clean status

Permethrin; tetrachlorvinphos

What is being shown?

Keep your distance; isolate birds from visitors + other birds; keep it clean; change clothes, clean boots, tools, equip.

Permethrin; Tetrachlorvinphos

Genetic or age resist.; innate: cough, mucus, enzymes, skin, mucosa, stomach acid; Passive + acquired: Ab-med., cellular
