Spray-dried porcine and bovine plasma are equally efficacious and superior than ovine plasma when fed to newly weaned pigs

摘要

Spray-dried plasma (SDP) and similar products have been used by the pig industry for over 20 years to support young pigs prior to and after weaning (Tucker et al. 2011). To date, the comparison of porcine and bovine SDP has shown porcine SDP to produce superior growth performance and lower mortalities after weaning (Torrallardona 2010). However, there are recorded comparisons of ovine SDP with either bovine, porcine or mixed-species plasma in weaner pigs. This experiment tested the hypothesis that porcine, bovine and ovine SDP would be equally efficacious in improving growth performance of weaned pigs.
