Official Feed Control Linked to the Detection of Animal Byproducts: Past, Present, and Future

Abstract

In the context of the expansion of the human population, availability of food, and in extension of animal feed, is a big issue. Favoring a circular economy by the valorization of by-products is a sustainable way to be more efficient. Animal by-products are an interesting source of feed materials due to their richness in proteins of high nutritional value. Prevention and control efforts have allowed a gradual lifting of the feed ban regarding the use of animal by-products. Nevertheless, the challenge remains the development of analytical methods enabling a distinction between authorized and unauthorized feed materials. This review focuses on the historical and epidemiological context of the official control, the evaluation of current and foreseen legislation and the available methods of analysis for the detection of constituents of animal origin in feedingstuffs. It also underlines the analytical limitations of the approach and discusses some prospects of novel methods to ensure food and feed safety.

Nutrition and Animal Agriculture in the 21st Century: A Review of Future Prospects

“…Furthermore, the integration of insects into the feed matrix contributes to the circular economy paradigm by transforming organic waste into invaluable protein resources (Oonincx & Boer, 2012). Historically, animal by-products, such as blood meal and bone meal, have served as notable constituents of animal feed formulations (Lecrenier et al, 2020). These by-products are replete with proteins and proffer a fertile source of essential nutrients for animals.…”

Can insects be used in the nutrition of ruminants?

“…Regarding ruminants, the use of insect-derived PAPs has been much less investigated so far. This is partly the consequence of the legislative framework currently applying in most developed countries (Lecrenier et al, 2020). For instance, under the current European Union (EU) regulations, insect-derived PAPs are only authorised for use in the nutrition of monogastric (aquaculture, poultry, and swine) animals (European Commission, 2017;.…”

Digestion Profiles of Protein in Edible Pork By-Products

“…A large amount of by-products from animals (pig, beef, chicken and fish) are produced, which weigh around 20–50% of the relevant animals [ 1 , 2 , 3 ]. Taking China as an example, approximately 163 million pigs were slaughtered in 2020, producing over 6 million tons of pig blood, 60 million tons of pig bone and almost 1 million tons of viscera [ 1 ].…”
