Resumen

The aim of this work was to study the relationship between soluble fiber and the n-6/n-3 ratio on growing rabbit performance. To this end a factorial design was used with two soluble fibre levels (7.8 vs. 14.4%; LF and HF) and two n-6/n-3 ratios (3.5 vs. 13.4; Ln-3 and Hn-3) resulting in four experimental diets (LF_Ln-3, LF_Hn-3, HF_Ln-3 and HF_Hn-3). A total of 160 rabbits weaned at 26 d of age were used (40/diet). Growth performance and mortality were recorded from weaning to 62 days of age. Two weeks after weaning, the increase in soluble fiber reduced the mortality from 20 to 2.5% (P <0.001), but at the end of fattening period there were no differences (30% on average). From 26 to 39 d of age, feed efficiency increased by 7 % (P = 0.011) in rabbits fed the HF diets as feed intake tended to decrease by 5% (P = 0.10), and no differences in energy and protein digestibility were observed. From 39 to 62 d of age, animals receiving a higher level of n-3 tended to increase weight gain by 4% (P = 0.057) compared to those fed with the lowest level of n-3. In the overall period animals receiving diets with high levels of n-3 tended to weigh 60 g more (P = 0.11) and higher weight gain 3% (P = 0.10) than those who received a lower level of n-3. Moreover, feed efficiency of rabbits receiving the highest level of soluble fiber was 3% (P = 0.040) higher because feed intake tended to decrease by 3% (P = 0.091).
