Although you will find as numerous systems of pig production as you will find individual farms, these may be split into two major types: indoor or outside pig production.
Indoor pigs farms feature herds of pigs stored inside a relatively small, carefully controlled area, usually with some type of heating and cooling, frequently with liquid feeding systems, and (progressively) 'high health". Scalping strategies are frequently known to as factory' or 'intensive' production.
Outside pigs feature breeding pigs (sows and litters) being continued free-draining arable fields for a couple of years per site, using 'arks' and electric fencing. Greater than a third from the United kingdom herd are increasingly being stored by doing this, by having an growing quantity of pigs being elevated to slaughter weight outdoors too.
Both systems get their 'pros' and 'cons': let us begin by analyzing the positive options that come with both.
Inside you will find the benefit of environment control: piglets could be born and elevated in the right temperature adult creatures could be stored awesome within the summer time and warmer during the cold months - additionally they do not get the chance to obtain sunburnt and air flow, especially the appearance of draughts, so harmful to pig health, could be controlled. You may also control the feed consumption of located pigs, and therefore are able to better reduce wastage (essential in nowadays of growing feed costs) - it is also simple to install computer controlled feeding techniques, for example automatic sow bird feeders and liquid feeding for fattening stock. Indoor farms tend to be productive than outdoors given the opportunity to control feed and atmosphere - you can acquire a greater degree of supervision and measurement and for that reason control of the numerous variables within an indoor situation. You can also establish and keep a higher health status for the herd, considerably reducing disease risks and challenges.
Outdoors though, you'd take advantage of much reduced capital costs, lower running costs, a genuine marketing benefit in nowadays when 'freedom food', 'outdoor bred' as well as 'organic' hold sway over customers who may be convinced to spend reasonably limited cost for such environment friendliness. There's a concept of greater welfare functioning for that outside pig (natural, able to better express it's 'inner pig'. Finally there is the very real benefit of using pigs like a 'break crop' 'cleaning' and fertilising a bit of arable land looking for weeding and refreshing.
Advantages, but how about the disadvantages?
Inside, the setup cost is three occasions greater (on the per sow basis) compared to an outside unit. Energy cost is high, and slurry disposal can generate problems (although welcomed through the arable boys once spread and integrated into the soil), and definitely a substantial cost. Our prime population density of the intensive farm has it's own problems too: illnesses spread like wild-fire whenever they access the herd, and also the smell could possibly get offensive, especially on hot days. Welfare factors are important too - it's simpler to fall foul from the law inside than out (stocking densities and environment enrichment spring to mind).
Outdoors, the greatest troubles are lower productivity and extremes of weather (on my small outside unit I viewed water freeze because it arrived on the scene of the four inch valve on the bowser one winter). Getting quality employees are an growing problem too - every single day outdoors isn't always idyllic. Vermin control and also the health status from the herd is really a potential problem too, out of the box the control over the feeding herd should that be stored outdoors (appetite control, feed conversion, growth rates and feed wastage all will be large challenges which will require a healthy premium cost to warrant).
That's it. "Shifts and roundabouts" as the saying goes - "six of 1 and six from the other". Most likely the best is really a compromise - well-designed structures and slurry management systems, with pipeline given body fat pigs (using dairy waste for instance), loose housing and a lot of hay. Toss in some high welfare features like Electronic Sow Bird feeders and lots of environment enrichment, and keep a higher health status, maybe you will have the very best of both mobile phone industry's? One factor I understand without a doubt is the fact that pigs get as miserable once we do on snowy, icy, wet and windy days, and, like us, they find draughts and temperature equally uncomfortable.
