PROTEIN-RICH FEEDSTUFF WITH RESISTANCE TO LOWERED DIGESTIBILITY DUE TO HEAT DAMAGE

摘要

Protein-rich feedstuffs which contain at least one protein feed material and either betaine or at least one feed product which contains betaine are resistant to reduction of digestibility as a result of heat damage during drying.

主权项

1. A process of making a protein-rich feedstuff, said process comprising:
(i) mixing (a) at least one protein feed material with (b) betaine or at least one feed product which contains betaine, to obtain a mixture; and (ii) drying said mixture, to obtain said protein-rich feedstuff, wherein: the protein-rich feedstuff comprises the betaine in an amount of not less than 3.5 grams of betaine per 100 grams protein in the protein feed material; and the protein-rich feedstuff comprises at least 20 wt. % protein on a dry matter basis.
