High-Oil Oat Groats for Weaned Pigs
Posted in: Prairie Swine Centre by admin on January 1, 2007
After weaning, young pigs need highly palatable, digestible diets, devoid of antinutritional factors and with high digestible energy (DE) content. Feed ingredients corresponding to that description are generally expensive and choice is quite limited. One alternative could be oat groats (dehulled oats) with high oil content. Oat groats are well consumed and digested by young pigs and have the highest lysine content among all the cereal species used in swine nutrition (Van Barneveld et al., 1998; J. Sci. Food Agric. 76, 277). The specific objective of this study was to determine the nutritional value of high-oil oat groats and their effect on the growth performances of weaned pigs. The groats contained 95 g oil, 159 g crude protein and 3,724 kcal DE/kg DM. Weaned pigs fed for 4 weeks (7 to 22 kg) with diets containing graded levels (0, 15, 30, 45%) of oat groats, incorporated at the expense of wheat and soybean meal (85%-15%), presented average daily gains similar to those obtained with wheat. In conclusion, high-oil oat groats can replace wheat in diets for weaned pigs because of the high protein content and the relatively good quality of the oat proteins.
