Choice feeding – whole grain diets for pigs and chickens
Soya beans are roasted in a half metal drum under a fire to eliminate the soya beans natural insect repellant – trypsin inhibitors. The heating de-natures this compound and allows the animals to consume large amounts of soya without adverse effects.
However, for smallÂ chicks maize and roasted soya are milled to a coarse grain in a hammer mill with the sieve removed. A starter mix is made and maize is given to the birds in order to supply them with an option for high protein and high carbohydrate. Layers are given whole grain diets after around 3 months.
All the farm animals are fed grain at 16hrs daily, only once. This is done to allow the digestive system to rest for a period. This is said to promote a healthy digestive system.
For both pigs and chickens are allowed the ‘free choice’ feeding and continuously monitored for their intake of hi-carb and hi-protein. The feed is adjusted according to demand by looking at the appetite of the animals for both feeds withinÂ a 2 hour period. ie. if they finish the maize quickly, more maize is given on the following day. If the roasted soya is consumed more quickly this suggests the animals need more protein.
We are very happy with the results of this type of feeding as it allows us to match the dietary requirements of the animals with minimum cost for labour/transport/milling and mixing.
