Variability in Distillers’ Co-Product Compositions and Their Nutritional Availability for Pigs: Insights from a Systematic Literature Review
Abstract
Simple Summary This study aimed to evaluate the nutritional diversity of distillers’ co-products in pig diets. Two databases were used. The first, based on 49 scientific studies from 2003 to 2022, focused mainly on corn-derived distillers’ co-products, with most analyzing dried distillers grains with solubles (DDGS). Variations in the nutritional composition were noted, especially in the net energy and digestible lysine content, from 2015 to 2022. The second database, created from field surveys in Brazil (n = 1550), analyzed the DDGS samples. The results highlight significant variability in the crude protein and ether extract, emphasizing the need for plant-specific nutritional assessments to improve the sustainability of pig production.
How strong is the evidence?
Evidence Hub reads this as a review, done in animal, not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 1,550 participants or records.
