Evaluación de cuatro niveles de morera (Morus alba) en engorde de conejo bajo normativa orgánica

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%.
