Incorporating green roughages trifolium alexandrinum l. and avena sativa l. into ration was studied in rabbits. Seventy-five "New Zealander X Californian" kits weaned at 30 and 35 days of age were divided into 5 pens to receive one of five diets: four experimental and a control diet. Experimental diets were based on the distribution at will of green roughages complemented with a commercial, concentrate at rates of 40 and 60% of kits daily needs while the control diet included only concentrate. Live body weights at the end of the trial ranged from 2, 21 kg to 2, 30 kg and weight daily gains were between 26, 9 and 32, 7 g/j. Furthermore, mortality rate was below 4% for all regimens. Trifolium alexandrinum l. + 60% concentrate resulted in the best growth performances among experimental diets. These performances were comparable to those observed in control kits. Meat of kits receiving Trifolium alexandrinum l. + 60% concentrate was rich in water, minerals and myoglobine and had low content in collagéne and fat and consequently was highly rated for its sensorial quality.
