Summary

Spray-dried plasma improves piglet weight gain and feed intake in the first week post-weaning. It also enhances intestinal structure and reduces E. coli, potentially replacing antibiotics in piglet diets.

Area of Science:

  • Animal Science
  • Nutritional Science
  • Veterinary Medicine

Background:

  • Weaning is a critical period for piglets, often associated with reduced feed intake, growth, and gut health.
  • Dietary strategies are crucial for mitigating post-weaning challenges and improving piglet performance.
  • Spray-dried plasma (SDP) is a protein source with potential benefits for young animals.

Purpose of the Study:

  • To review the effects of spray-dried plasma (SDP) on weaned pigs.
  • To evaluate SDP's impact on feed intake, weight gain, intestinal morphology, and E. coli levels.
  • To assess SDP's efficacy across different weaning ages and its potential as an antibiotic alternative.

Main Methods:

  • A systematic review of 25 scientific papers published within the last 15 years.

  • Analysis of studies examining SDP inclusion in diets for piglets weaned at various ages (14, 21, 28, 35 days).
  • Evaluation of reported data on feed intake, weight gain, small intestine villi height and crypt depth, and E. coli counts.

    • Main Results:

    • SDP significantly improved weight gain and feed intake during the first week post-weaning, particularly for piglets weaned at younger ages (14-28 days).
    • Dietary SDP positively influenced intestinal morphology, increasing villi height and crypt depth when replacing skim milk.
    • Inclusion of SDP led to reduced E. coli populations in the small intestine of pigs weaned at 21, 28, and 35 days.
    • SDP demonstrated potential to replace antibiotics in diets for pigs weaned at 28 and 35 days.

    Conclusions:

    • Spray-dried plasma offers significant benefits for piglet performance and gut health, especially in the early post-weaning period.
    • The efficacy of SDP is influenced by weaning age, with greater benefits observed in younger piglets.
    • SDP is a viable alternative to antibiotics in piglet diets, contributing to improved intestinal health and reduced pathogen load.
