What is the objective of on-farm ventilation system?
Constant air movement and renewal
is a type of ventilation system commonly used in pig housing to manage the indoor environment and provide optimal conditions for the pigs.
Tunnel ventilation
Effective in hot climates or during hot seasons, as it can help to reduce heat stress in the pigs by providing a cooler environment.
Tunnel ventilation
Purpose of Ventilation System
- To remove excess heat
- To remove excess moisture
- To minimize dust
- To provide oxygen for respiration
must be designed and constructed for the health and well- being of the pigs in order to obtain maximum performance and savings in labor costs.
Hog houses
The long axis of the building must order be laid in an _______-______ direction to protect the animals from direct sunlight
East-west direction
It can accommodate non- pregnant and pregnant sows, gilts, and piglets. It can also be used for growing-finishing operation.
Conventional or all-purpose housing system
This system combines several farm operations into one building.
Conventional or all-purpose housing system
This system provides the animal with proper space and comfort during each phase of its life cycle.
Lifecycle housing system
This system is designed to to provide animals with proper space requirements, maximize labor efficiency, and promote better biosecurity
Lifecycle housing system
The life cycle housing system is composed of the following units:
- pregestation and boar,
- gestation,
- farrowing and nursery
- and growing-finishing
Four unit of lifecycle housing system
- Boar unit
- Gestation unit
- Farrowing unit
- Growing-finishing unit
must have sufficient space to accommodate mating activities.
Breeding house
For Pregestation and Boar unit
• The air moisture level (relative humidity) should be maintained at about __%.
• Approximately __-__ hours of light should be maintained daily.
70%
16-18%
House for recently bred, pregnant gilts and sows in individual stalls to prevent injury, feed competition, and unnecessary stress that may lead to failure in fertilization or abortion.
Gestation unit.
Transfer pregnant animals to this unit one week before the expected farrowing date.
Farrowing unit
Important points to consider in Pens for sows with piglets
- Protection of piglets against crushing
- A good view of the sows and piglets
- Reachability of the piglets
- Adjustability of the pen
- Cost of labor
Piglets may stay here until weaning because of its elevated slatted floor.
Elevated Farrowing Pen
This is the pen in which the sow and piglets stay up to weaning. The piglets could stay in this pen even after weaning up to market weight.
Farrowing Rearing Pen
It is a movable for a sow with her piglets during the first 2-3 weeks. After which, the crate is removed.
Farrowing Crate
• This is not advisable for a large groups. One litter per pen will be enough to get good results. Space requirements depends on the transfer weight.
Pens for Weaners
Adopt an “all-in, all-out”’ scheme per pen. Animals can be housed in conventional pens with concrete floor and partition walls made of either concrete, round bars, or G.I. pipes.
Growing-finishing unit.
It is also called the feeding/lying box/stall. Stalls and tethers are normally cleaner when the rear half of the floor area is slatted.
Individual housing
Stimulation to come in heat. Heat is more visible (sows mount each other). Simple design of building can be used separately when exercise and/or dunging is outside.
Group housing
