A large variety of fattening units can be found over the country. It ranges from small farm fattening units where the farmer feeds 5 – 30 lambs or cattle weaners at a time to large commercial feedlots with standings of up to 50 000 cattle at a time.
The small feedlots usually feed the animals about twice a day by hand, while the big commercial feedlots use automated machinery that automatically feeds the animals every hour of the day and night.
The commercial feedlots also use a different type of growth promoters to achieve a better average daily gain, but because these products are very expensive their use in small fattening units is limited.
