Nutritional aspects
Nutritional attributes 

Bakery waste, such as stale bread and crumbs, can be dried and mixed for animal feeding. It is rich in fat and carbohydrate, but the protein quality and the vitamin content are low. It has been used as a substitute for grain in rations for all classes of livestock. When bakery waste is fed in large amounts, it must be supplemented with vitamin A, minerals and good-quality protein.

Ruminants 

It has been included up to 30% in cattle rations without affecting palatability.

Pigs 

For pigs it can replace all grain.

Poultry 

As the product is rich in salt, more than 15% cannot be used in poultry rations.

Rabbits 

Stale bread or bakery wastes are traditionally used to feed rabbits in small familial units and backyard systems in the different parts of the World, together with other kitchen, garden or market wastes (Rastogi, 1983; Degen et al., 2009; Christodoulopoulos et al., 2001; Garcia-Lopez et al., 2006).

In balanced diets, bread wastes may completely replace cereals with interesting economic results (Al-Shami et al., 2009) and were included in growing rabbits ration without problem up to 40% of the diet (Ayandiran et al., 2016).

This type of feed is an interesting source of energy (mainly starch) for rabbits but with a low protein content (8-12%) and a quasi absence of fibre (~1% crude fibre). The digestible energy content was estimated between 14.9 and 17.9 MJ/kg DM according to the authors (Ramchurn et al., 2001; Voris et al., 1940.

Whatever the nutritive value, as for many by-products or waste products in general, a special attention must be given the mycological status of the product (absence of mould) and to the absence of mycotoxins (Mézes et al., 2009).
