Classic “causes” of pre-weaning diarrhoea

 

1

A range of disease agents – E. coli, TGE, Coccidiosis, Clostridia, Rotovirus etc.

2

Almost any air movement is undesirable >0.2 m/sec (> 50 feet/min)  is  a draught

3

Chilling of the piglets, check lying patterns and creep temperatures (ideally 30•C)

4

Variable temperatures in the creep

5

Damp floors particularly in the creep area

6

Poor colostrum intake

7

No milk in the sows, check udder line – mycotoxins and management

8

Degree of cross-fostering

9

Piglet treatments not been clean enough,  Check cross-contamination between healthy and sick piglets

10

Infection transfer - is there a separate brush and scrape for each room, foot baths, personal hygiene

11

Poor room cleaning between batches

12

Number of sows farrowing each week, application of all-in all out and pig flow

13

Presence of udder oedema

14

Amount of navel bleeding

15

Type of iron injection utilised, more post-weaning scour

16

Vaccine storage protocols

 

As part of the investigation, if post-mortem examinations are required, select an acutely sick piglet, not a chronic piglet which is likely to have secondary infections which may mask the actual causal agent(s).
