Common names

Description 

Hog hairs are more difficult to hydrolyse than feathers. The fibres disintegrate when pressure-cooked (3.5 kg/cm) at 148°C for thirty minutes.

Nutritional aspects
Nutritional attributes 

The processed product is a valuable feedstuff because of its high protein content, but it is deficient in methionine, lysine and tryptophan. The amount of the meal which can be used effectively under ordinary conditions is limited.

Pigs 

Hydrolysed hair seems to be unsuitable for pigs.

Poultry 

The inclusion of more than 2-2.5% in poultry feed does not seem advisable. Also hydrolysed wool has been used as a replacement for soybean meal at levels of 2-5% with good results.
