28/04/2017: The underestimated uses of fishmeal and fish oil in swine and poultry diets

by Dr Neil Auchterlonie, Technical Director, IFFO

Decades ago fishmeal and fish oil were the mainstay of pig and poultry production, but with the growth of aquaculture from the 1960s onwards these materials have been diverted largely towards feeding fish


With a very broad nutritional profile, their use as feed ingredients for pig and poultry does have large potential advantages, not least of which relate to farmed animal health and welfare. Their high quality is reflected in the market price, but least cost formulations may not always produce higher profit margins once the production benefits are taken into account.

Animal protein sources have been known to provide performance advantages in feeds for the production of both swine and poultry since at least the 1880s, when the rendering industry became established with developments in infrastructure, logistics and technology (Denton, et al., 2005).

Periods when animal protein sources have not been available, and where feeds were vegetable-based, such as during the Second World War, coincided with a dip in production efficiency (Ibid.), so their importance is clear, and more recent science continues to validate the position (e.g. Yun et al., 2005).

Fishmeal, as one of those animal protein sources, has a long history of use as an ingredient in pig and poultry feeds. Records of fishmeal and fish oil as ingredients in pig feed stretch back at least a century (Ashbrook, 1917), and have been known in poultry feeds for a similar length of time.

Today, they are important strategic ingredients in feeds for both animals, where the nutritional benefits provided in weaning and other early life-stage diets are known to extend throughout the production cycle.


Excellent nutritional benefits are provided by fishmeal through the relatively high protein content (62% to >70%, Sauvant et al., 2004) as well as the wide range of micronutrients including the amino acid profile, and the vitamin and mineral composition.

A five percent or less inclusion (dry weight basis) is typical in terrestrial livestock feeds, and a review of the performance advantages including sows, weaning pigs and broilers is provided by Cho & Kim (2011) clearly illustrating some advantages in growth.

Two IFFO-sponsored studies, one in 2009 (conducted by Prof. Haifeng at the Animal Husbandry and Veterinary Research Centre of the Beijing Academy of Agriculture and Forestry), and one in 2014 (conducted by Prof Ma at the China Agricultural University in Beijing) have shown how both fishmeal and fish oil can improve both the growth performance and health of weaned pigs.

Whilst acknowledging the high cost of the material, this work shows that fishmeal and fish oil may also support achievements in improved bioeconomic efficiency of production. Even though fishmeal carries a high value and is a relatively expensive ingredient, therefore, the benefits from its incorporation may outstrip competitor ingredients through an influence on the economic production model to achieve improved profit margins.
