I receive many questions about the egg test described in the chapter on pet food ingredients in the book "Boilies".
Basically it is a method of working out whether a mash or any pelleted feed can be included in the mix without compromising the mechanics of the mix.
There are mash that are in themselves ready-made mixtures to be rolled by adding only eggs and liquids.
Obviously the test can be done with pellets only after having ground them with a suitable mill, reducing them to flour, while with the ornithological birdfoods, you can also try without micronizing, bearing in mind that reducing the grain size always helps the mechanics on the table.
Egg test simplified version:
Crack a medium egg and add the mash a little at a time, until you get the best consistency for extruding and rolling.
If we have achieved the result with 100-130 grams of mash, it means that the product rolls perfectly without any additions and corrections and can therefore be included in the mix in high dosages (50-70%).
If we have reached the result with less than 100 grams, it means that the product is rich in starch and can be added up to a maximum of 40% and corrected with appropriate protein ingredients (such as skimmed milk).
If, finally, we have used more than 130 grams, it means that the product is very high in protein and that it lacks starch, so it can be used to make mixes to be rolled with little liquid, at a maximum of 30%, or corrected by adding starchy flours such as corn.
In the article we have always referred to "mash" but the test can also be done with dog and cat food, pelleted food for pigs or dairy cattle, etc. This is a way of understanding how the feed is used and how it can be used.
This is a way of understanding how there is a whole world of semi-processed products that are almost ready-made, nutritious and complete mixes, simply by micronising them with the aid of a grain mill.
This practical tool allows us to create the mix directly by mixing the various flours together and micronising the pellets at the same time.
This practical and very economical solution, given the wholesale price of some pellets, allows us to make large volumes of very interesting bait.
