The degu diet consist of plant matter from shrubs and herbs including seeds. The amount of seeds is 20-40% of the whole diet, with a seasonal fluctuation from 5% to over 60% (Meserve 1981; Meserve et al. 1983).
Degus prefer the following fodder plants:
- Erodium cicutarium (introduced weed from Europe)
- Porlieria chilensis (acacia like native shrub)
- Baccharis species (native shrub)
- grasses (e.g. Bromus, Stipa etc.)

In past the Chilean wine palm (Jubaea chilensis) was a wide spread species building large palm forests. Nowadays it's a threatened species and only small forest paches could survive (Gonzalez et al. 2009). One of them is in Ocoa, near Santiago de Chile. Here the degus feed on the nuts of this palm, the so called "coquitos". They are used as energy rich staple food and as reserve for the dry months. I tested this nut and the degus liked it.

The coquitos (they are really little cocosnuts):
Btw. the taste remembers also to the cocosnuts (I had to taste it of course ;-) ).

And the palm:
The photo is from Switzerland. The palms grow here in parks in the mediterranean like southern part near the frontier to Italy.

Suitability as animal food:
In wild the nuts are used by cururos (Spalacopus cyanus, rarely also kept as pet), degus, olive grass mice (Abrothrix olivaceus) and Bennet chinchilla rat (Abrocoma bennetti). In addition also the introduced ship rats (Rattus rattus) feeding on this nuts and they are also heavily harvested by humans. The shell of the nuts is thick and hard, but the degus are used to crack them, also domestic rats (Rattus norvegicus) learn quickly to crack them (here the proof: cracked nuts - the left nut is a coquito and right a macadamia).

Nutritional content:
The nuts contain 3,5 % water, 7,0 % protein, 67,3 % fat, 11,6 % crude fiber und 1,1 % minerals (Masson et al. 2008).
