Check out these key facts on feeding pigs
Pigs feed on both vegetable and animal products, and can compete directly with humans in this regard.
Careful consideration needs to be given to this factor in local areas where foodstuffs are scarce and it is advisable that in such circumstances pigs are given feed that is not useful to humans. This commonly means by-products and other waste from crop and animal production or swill.
However it is important to note that pig feed needs to contain a good balance of protein, energy, minerals and vitamins. An appropriate balanced ration will keep a pig in good health, develop its weight, and maintain its reproductive capacities.
The type of feed administered will also directly affect meat quality at slaughter. For example if a pig is fed with maize, which contains oily fats, this will make the meat tender.
Feeding in very hot or very cold conditions can reduce the feed intake and thus feeding times need to adapt accordingly. Sufficient local feed and water resources have to be available in areas where smallholder pig production is to be promoted.
One of the challenges is the availability of adequate feedstuffs despite seasonality.
