Abstract—In rabbits feeding, a minimum fibre intake is essential 
to avoid digestive disorders. However, this concentration of fibre is 
not easy to obtain when formulating feeds, without reduction of 
nutritional value. The incorporation of olive cake as a source of fibre 
can allow a better balance between different fibre fractions and 
reduce health disorder. However, for a practical use of any raw 
material, it is necessary to know its chemical and nutritive value. The 
objective of this study was to assess the nutritive value of three-stage 
olive cake for growing rabbits. As well, the nutritive value of sun-
dried three stage olive cake (TSOC) for growing rabbit was studied 
by comparing 3 diets containing increasing incorporation level of 
COC (0, 10 and 20%) in substitution to basal diet. Three groups of 12 
rabbits (individually caged) were fed ad libitum the three diets. The 
faecal digestibility of the diets was measured between 42 and 46 days 
of age. Chemical analyses were conducted at INRA Toulouse (UMR 
1388 GenPhySe, France).The average chemical composition shows 
that TSOC is a fibre source since it contains (% DM) 78.7% of NDF, 
55.4% of ADF and 24.3% of ADL. The substitution of 20% of basal 
diet by three stage olive cake reduced the digestibility of organic 
matter, crude protein and NDF from 67.8 to 55.3%, 80.4 to 75.3%, 
31.5 to 18.4% (P<0.001) respectively. The digestible energy (DE) 
content of the olive cake estimated by regression was 2.94±0.52MJ 
DE/kg DM. Protein digestibility of three stage olive cake was 
estimated at 37.0%, corresponding to a digestible crude protein 
concentration of 22.4±6 g DP/kg DM. Crude olive cake could be 
considered as a moderate source of nutrients for growing rabbit but a 
good fibre source.
