The chemical analysis was carried out in the laboratory of Bromatology, and the in situ digestibility in the fifth Punzara of the National University of Loja. 21 samples of 1 kg were obtained, by means of sampling by conglomerates and the following variables will be studied: dry matter (DM), ash (Cz), crude protein (PC), crude fiber (FC), in situ digestibility and energy content. An analysis of variance was performed, and Tukey's test was applied at 5%. The results have not been differentiated in the content of MS, Cz and FC according to provenance and variety, with mean values of 86.46%, 8.35%, and 73.98% respectively. The PC content varied according to the origin (p = 0.0007), observing the highest percentage in Olmedo with 12.6%; While according to the variety no significant statistical difference has been changed. The in situ degradability indicates the maximum value in the Rosita Iniap 381 variety with 27.02%; meanwhile, according to the origin, the highest percentage corresponded to the samples of the Olmedo canton with 27.51%. Regarding the energy content, the statistically significant difference is observed (p = 0.02), with the highest value in Olmedo (1.20 Mcal / kg DM). It is concluded that the peanut shell has a bromatological composition and nutritional value; so it can be an interesting alternative for the feeding of ruminants, especially in the period of greater scale of forages.
