Summary

The nutritive value and the influence on digestibility and pellet feed intake of mango tree (Mangifera indica L.) and black mulberry (Morus nigra L.) leaves fed ad libitum were studied using growing California rabbits.
An increase in ingested crude fibre (very low in commercial pellets), total dry matter consupmtion in both experimental groups (pellets and mango tree leaves - P + M, pellets and black mulberry leaves - P + BM) and a decrease in pellet intake (-28.5 %) in the P + BM group were observed.
The green leaves as a supplement to the control diet pellets (P) significantly reduced the protein digestibility (P < 0.05) in the P + BM group and the ether extract (P < 0.01) and energy digestibility (P < 0.05) in both experimental groups (P + M and P + BM), whereas crude fibre digestibility improved in both experimental groups (significantly in the P + BM group).
The green leaves in combination with commercial pellets had no negative effect on animal health during the experiment and are recommended as an alternative source of crude fibre.

Key words: mango leaves; black mulberry leaves; digestibility; growing rabbits
