What does AiAO mean and why is it used?
All-In–All-Out (AIAO) swine production is a system that keeps animals together in groups. Animals from different groups are not mixed during their stay on the farm. The groups are closely matched by age, weight, production stage and condition.
How long do pigs stay in the nursery?
36 to 46 days
The average time spent in the nursery ranged from 36 to 46 days. Because pigs are typically weaned earlier and enter the nursery at a younger age on large and medium sites, these pigs spent more time in nurseries on average than pigs on small sites (Table 1).
What are the disease prevention advantages of all in all out AiAO management?
One of the greatest advantages of AiAO is that it breaks the chain of infection and prevents disease buildup. infectious organisms have two main sources: other pigs and the environment. in an AiAO system, infection from other pigs is reduced or eliminated because once a group is established, no pigs are added to it.
What is pig flow?
The systematic approach to raising pigs in a multi-site production system, in terms of where the pigs are housed and how long they are fed, is generally called pig flow. This complex process is most often approached in a segmented fashion, not looking at all barns at the same time in relation to each other.
What causes porcine stress syndrome?
Porcine stress syndrome, sometimes called malignant hyperthermia or transport myopathy, is a complex, genetically transmitted myopathy usually triggered by stress or excitement. It also can be triggered by several anesthetics, including halothane, and by depolarizing muscle relaxants.
What does all in all out mean?
This term implies the complete emptying (of animals) of a room, quarters or building, and its cleaning and disinfection (without the animals inside) before introducing a new batch.
What are two signs that your pigs are overcrowded?
An early warning is heads and ears rising and increased crowding within the group. Pigs will often stay in a bunch rather than leave the bunch to get away from the handler. Increasing pressure and aggressiveness towards pigs that are bunching encourages tighter bunching.
