Animal protein represents a high quality ingredient. However it cannot be used freely in all production systems as there are certain restrictions. In poultry nutrition, meat and bone meal (animal protein), blood products (animal protein) and protein derived from insects can be used. This option makes it possible to formulate diets with these raw materials if their price is favorable when compared to proteins of vegetable origin,.
On August 2021, Commission Regulation (EU) 2021/1372 repealing the ban on feeding non-ruminant farmed animals with animal-derived protein was published in the Official Journal of the European Union.
This authorisation does not allow the use of animal proteins of ruminant origin and does not allow protein recycling within the same species.
↳ This implies that in poultry nutrition, meat and bone meal(animal protein), blood products (animal protein) and insect-derived protein may be used.
This alternative makes it possible to formulate feed with these raw materials including animal protein if their price is favorable when compared to other protein sources.
This article intends to make a short review of these protein concentrates and their characteristics which are the following:
Very digestible
Rich in amino acids and phosphorus
High in vitamins
A summary of the nutritional characteristics of some of these raw materials is presented in Table 1, along with the most commonly used protein concentrates:

Meat and bone meal
Meat meals constitute a set of products that due to their origin and composition, can have different nutritional characteristics.
Variable proportions of slaughterhouse by-products are used in its manufacture, including:
Meat trimmings
entrails
Inedible organs
Hair, hooves or digestive contents are not used in the production of meat meal
↳ When bones are included in meat meal, it is considered as meat and bone meal.
To ensure sanitization during manufacturing, the product ...
