1

what are the 5 diseases seen in young chicks?

1. yolks infection
2. septicaemia / salmonellosis
3. starvation
4. aspergillosis
5. rotavirus

2

what are the two causes of yolk sac infection?

infection of eggs via omphalitis / navel infection
environmental spread

3

what is the main agent that causes septicaemia in young chicks?

salmonella app

4

what are the main Sx of starvation in young chicks?

high mortality, lethargic chicks, empty gizzard on PM or gizzard containing bedding material

5

what causes aspergillosis?

aspergillus fumigatus

6

how do chicks become infected with aspergillum?

via feed, bedding or environment

7

what are the main Sx of aspergillosis in chicks?

gasping, weight loss, mortality

8

how do chicks become infected by rotavirus?

via eggshell or environmental contamination

9

what are the main Sx of rotavirus infection in chicks?

depression, dropped wings, closed eyes, huddling, ruffled feathers, death

10

how is rotavirus infection in chicks Tx and Px?

Tx = disinfectant in drinking water or via spray
Px = frequent egg collection with cleaning and good hygiene

11

which game bird spp chicks does rotavirus affect?

pheasants and partridge

12

what 4 diseases mostly affect growing game bird poults?

1. Spironucleosis / Trichomoniasis
2. Coccidiosis
3. Parasites
4. Enteritis / Dysbacteriosis

13

what are the three causal agents of Spironucleosis / Trichomoniasis?

Spironucleus meleagridis
Trichomonas gallinae
Hexamita

14

what are the Sx of Spironucleosis / Trichomoniasis infection?

watery D+ (often yellow, frothy), dehydration, weight loss, lethargy

15

how is Spironucleosis / Trichomoniasis Dx?

Spironucleus = smear of duodenum / ileum
Trichomonas = smear of caecum

16

how is Spironucleosis / Trichomoniasis Tx and Px?

Tx = AntiB
Px = environmental hygiene, appropriate stocking density

17

what is the main spp isolated in coccidiosis of growing game bird poults?

E. colchici in caecum

18

when is coccidiosis most common in growing poults?

15d to 16wks

19

what are the main Sx of coccidiosis in growing poults?

weight loss, lethargy, ruffled feathers, dropped wings

20

how is coccidiosis Tx and Px?

Tx = toltazuril or amprolium
Px = in-feed coccidiostat drugs

21

what are the main enteric and respiratory parasites that affect growing poults?

enteric = ascaris, capillaria
respiratory = syngamus trachea

22

what does enteritis / dysbacteriosis cause?

scour seen in growing poults at 22/23wks leading to dehydration

23

what are the 4 main endoparasites of breeding gamebirds?

Syngamus trachea
Heterakis gallinarum
capillaria spp
ascarid spp

24

what is Heterakis gallinarum the intermediate host for?

histomonas meleagridis - 'blackhead'

25

what are the three main respiratory diseases of breeding gamebirds?

Mycoplasmosis
Coronavirus
Newcastle disease

26

which two mycoplasma spp affect breeding gamebirds?

M. gallisepticum and M. synovviae

27

what are the main sx of mycoplasmosis in breeding gamebirds?

swelling of infraorbital sinuses / eyes / nose, ocular discharge, difficulty breathing, egg drop, lameness

28

how is mycoplasmosis of gamebirds Tx and Px?

Tx = AntiB, macrolides
Px = vaccines used off-license

29

how do the sx of coronavirus differ in young vs. adult gamebirds?

Young = swollen kidneys, rate deposition in organs
Adult = sudden death, egg drop, rates in kidneys
