The objective is to evaluate the in vivo digestibility of 3 food rations at based on green fodders, products and by-products of maize and other food ingredients in the grasscutters in captivity. Methodology and Results: 24 grasscutters breeding aged five months divided into three lots of eight were installed in digestibility cages. The average food consumption ranged from 59.19 ± 8.80 g to 145.67 ± 6.44 g for the three rations. The apparent digestive utilisation coefficient (CUDa) in percentage for dry matter was from 78.10 ± 0.01 and 82.19 ± 0.02. That of the protein varied from 87.57 ± 5.69 to 90.83 ± 0.03% and the estimated crude fibre ranged from 74.51 ± 0.07 to 78.44 ± 0.03% for three rations. Conclusions and Application:The ration 2 consists of green fodders, products and by-products maize and other food ingredients is the most consumed and digested by of the grasscutters and ration 3 consists of products and by-products of maize is the least. The food ration 2 can be used by the grasscutters breeders for animal feed to improve the digestibility and performance for sustainable production of grasscutters.
