Blood plasma is used in particular in nursery pig diets because of its high digestibility and palatability. A meta-analysis of 75 studies showed that including 4-8% blood plasma in the nursery pig diet can boost feed intake levels by 41 g per day and daily weight gain by 37 g on average (Torralardonna, 2010). Blood plasma, however, can be expensive and many pig producers and nutritionists have searched for a lower-cost alternative
Fast protein:Protein that is degraded in the weaned pig’s stomach and contributes to better performance. Examples: blood plasma and wheat gluten meal.
Earlier studies by Trouw Nutrition showed that post-weaning diarrhoea is reduced when pigs are fed diets containing rapidly digestible protein sources. When using Kinetio Technology, Trouw Nutrition’s research shows that the stomach protein solubility of some protein sources is low, whereas the protein solubility of others is high. The more soluble the protein in the stomach phase, the faster the degradation rate of the protein. Blood plasma is one of the most quickly digestible proteins.
Results indicated that pigs fed Diets 2 and 3 had greater ADFI, ADG and FCR compared with pigs fed the control diet. There was no difference in performance between Diets 2 and 3, but Diet 3 (without blood plasma) was less expensive and resulted in a lower cost per kg gain and a better margin per pig.
