The levels used in this set of GF diets can be considered as a middle-of-the-road approach. The maximum level of DDGS that can be used depends on quality and availability of the each available product, pig carcass concerns, and of course, individual nutritionist’s preferences and experiences. In the past 20 years or so, corn distillers’ grains with solubles (DDGS) have become another typical U.S. Sorghum and some wheat are also used, where locally available, and canola meal may substitute some soybean meal when it becomes affordable to import from Canada. In all cases, the nutrient composition of the proffered diets is always calculated using the average of the initial and final projected weights for each sub-phase.ĭownloadable PDF: Growing pig feed formula (G1) Feed ingredientsĬorn and soybean meal are traditional staple ingredients used in feeding most pigs in the U.S., especially in the Midwest. Usually, in such cases, a delivery with a different feed is possible every week. Conversely, in large operations, more diets are possible, often depending on how long it takes to empty each building’s feed silo. In smaller farms, only two diets are fed (one G and one F), whereas in very small operations, a single diet may be fed during the whole growing-finishing phase. The first two diets are called growing (G), whereas the last two are called finishing (F). This phase of production comes after that of the nursery one, regardless of pigs being transferred to another facility or raised in wean-to-finish facilities.įor convenience, there are four diets being fed, one for every 25 kg body weight as follows: The growing-finishing phase in pigs ranges from 25 to 125 kg body weight (double figures to get rounded U.S.
