MORA-VALVERDE, David. Evaluation of four levels of mulberry (Morus alba) for organic rabbit fattening. Agron. Mesoam [online]. 2012, vol.23, n.2, pp.311-319. ISSN 2215-3608.

There was  developed a nutritional assessment of four diets  for rabbits whose main component was mulberry, under a supply management system consistent with organic production standards. A pasture housing management system was developed for this specific  organic experimentation. Four levels of mulberry  meal inclusion were evaluated in the full ration:  D1:  45%, D2: 55%, D3 and D4 65%: 75%. Daily weight gains  were reported in the order of 17.65 g/d. Diets D1 and D2, showed the  highest  growth  parameters  compared  to  diets  containing 65% (D3) and 75% (D4) for inclusion. The daily gain average obtained  values of D1: 17.26 g/d, D2: 21.57 g/d, D3: 14.77  g/d and D4: 17.00 g/d. In relation to feed conversion, diets D1 and D2 were more efficient in using feed for purposes than diets D3 and D4 (P <0.05). The total feed cost to bring animals to market weight was in the order of (D1: 2.26 U.S. $/kg, D2: 2.17 U.S. $/kg, D3: 2,49 U.S. $/kg and D4: 2.44 U.S$/kg). The fattening and market time resulted up to 2-3.5 under a feeding system exclusively with concentrates. A balance was detected regarding the reduction in the costs between 45 and 50%.
