Sow Stalls

 

Sow stalls have become a very contentious issue.  Consumers are becoming more educated about the source of their food and animal welfare is high on the agenda.  Many perceive sow stalls as cruel and unnecessary.

Changes are being made to the size of new sow stalls, requirements for existing installations and the maximum time that a sow can be kept in such stalls.  These requirements are spelt out in the Standards within the Model Code of Practice which are soon to become law.

Given the changes that need to happen, the expense of such modifications and the huge potential for future backlash from consumers in regard to sow stalls, it may pay to look at sow stall free alternatives to secure long term benefits for your business.

Problems with stalls

• Physical disorders such as joint damage, leg weakness and urinary tract infections due to lack of exercise and confinement on hard floors.

• Chronic stress, aggressive and abnormal behaviour due to boredom from excessive periods of confinement.

• Early culling of sows

• Note:  4.1.1 of the Code states that accommodation for pigs must be designed, constructed and managed in such a way that it protects pigs form adverse weather, injuries or other harm.

Benefits of stalls

• Easier for stockpeople to individually supervise and examine animals and feed/water them
• Easier to supervise and control adult pigs efficiently
• Protection of piglets and easier supervision of sows and piglets at farrowing

• Note:  these benefits are for handlers and stockpersons, not in the interest of the welfare of the pigs.
  

The Model Code of Practice states that all new installations of sow stalls must meet the following dimensions;

• Sows  0.6 m x 2.2 m
• Boars  0.7 m  x 2.4 m

All existing installations must now meet theses requirements of the Code:

• 4.1.1 Accommodation for pigs must be designed, constructed and managed is such a way that it protects pigs from adverse weather, injuries or other harm.

• 4.1.3 Sows and boars accommodated individually in stalls must be able to stand, get up and lie down without being obstructed by the bars and fittings of the stalls, lie with limbs extended, to stretch and to be ble to freely undertake such movements.            
  
• Specifically, in the case of sows and boars:

• a) They must be able to stand up at rest in a stall without simultaneously touching both sides of the stall.
• b) When they lie down in the stall their snouts and hindquarters must not simultaneously be touching the ends of the stalls.
• c) If the stall has bars along the top these must not be touching their backs when standing at rest or when they have their heads down feeding.
• d) The placement of drinkers and/or feed/water troughs in the stall must be easily accessible to them, but must not prevent ability to stand, stretch and lie down.
• e) When lying down, any contact with their neighbours in stalls on either side must not result in injury.

Note:  There is no phase out of existing small stalls if they meet the requirements above. There is no requirement to increase the size of these stalls to meet the dimensions for new stall installations. This essentially allows sows to continue to be kept in stalls only a fraction larger than their bodies indefinitely.

The Code also states that:

• 4.1.5 From 10 years after endorsement of the code a sow must not be confined in a stall for more than 6 weeks of any gestation period.

From 2017, for pregnant sows there will be a maximum of 6 weeks (previously 16 weeks) confinement in stalls, after which they will be released into group housing situations with other sows i.e. they will be only be allowed to be closely confined until they are mated and their pregnancy is confirmed. However, there are also provisions within the code to allow the producer to keep sows in stalls for longer periods. At this stage there is no indication of how these requirements will be enforced.

Alternatives to Sow Stalls

• Indoor group housing (smaller groups in large pens)
• Straw based shelters
• Free Range - outdoors

Farrowing Crates

Farrowing crates were conceived in an attempt to reduce the trampling and crushing of piglets by the sow by forcing the sow to lie down slowly and carefully due to the tiny dimensions of the crate.  However, data provided by Australian Pork Limited states that the current industry average for pre-weaning deaths of piglets stands at 13.1% so this figure would indicate that farrowing crates are not as efficient as we are led to believe.  It is plausible then to assume that there would be little difference to mortality rates if the sows were to farrow in straw filled pens.

A carefully designed pen, with one corner made inaccessible to the sow to form a creep area, is a cost effective way to farrow your sows.  The pens must be large enough to allow the sow to turn around and lay down with plenty of room for the piglets to escape her.  Straw bedding not only caters to the sows instinct to nest, it helps keep the piglets warm and dry when the litter is well maintained.  The bedding will also double as a valuable fertilizer on the farm, or a source of income (compost) when the sow is moved on.
