Podcast: Effect of hydrolyzed spray-dried bovine plasma and spray-dried bovine plasma sources on growth performance of weanling pigs

Dr. Charmaine Espinosa, a post-doctoral research fellow in the Stein Monogastric Nutrition Lab, discusses the Effect of hydrolyzed spray-dried bovine plasma and spray-dried bovine plasma sources on growth performance of weanling pigs. Adapted from a poster at the 2022 ASAS Midwestern Section meeting, March 14-16.

Research Report: Digestibility of starch, crude protein and amino acids in three sources of field peas ground at two different particle sizes fed to growing pigs.

Market opportunities for field peas (Pisum sativum L.) have rapidly increased for livestock feed and human food, due of the high nutritional quality of pea protein. However, as is the case with some feed ingredients, differences in soil, varieties, agronomic practices and growing method may change the nutritional characteristics of the peas as well as digestibility of nutrients. In addition, it is possible that differences in the particle size of field peas change the digestibility of energy and nutrients as has been reported for other ingredients. However, information about the effects of particle size of peas on digestibility of starch and amino acids (AA) are limited. Additionally, there is limited research to compare the digestibility of AA among field peas produced in different regions of the U.S. and Canada. Therefore, the objective of this experiment was to test the hypothesis that the apparent ileal digestibility (AID) of crude protein and starch, and the standardized ileal digestibility (SID) of AA in field peas may be affected by the particle size of the field peas and the region where the field peas were grown.
