Forty-five weaner Chinchilla rabbits (42-d-old, average weight 619 g) randomly assigned to three equal treatments, control with no probiotic and the other two with probiotics (107 CFU/g concentrate) Lactobacillus acidophilus and Lactococcus lactis. They were reared in individual cages and fed on ad libitum concentrate and wilted Lucerne (Medicago sativa) up to 91 d of age. Compared to control L. acidophilus improved weight gain (24.5 vs. 22.5 g/d, P < .05), whereas it was intermediate with L. lactis. Both probiotics improved the feed conversion ratio (3.91 and 3.96 vs. 4.34, P < .05) but no effect on dry matter intake (95.8 and 92.7 vs. 98.0 g). Dry matter and organic matter digestibility improved with L. acidophilus (72.8 vs. 67.0%, P < .05), whereas it was intermediate with L. lactis. Probiotics also improved (P < .05) digestibility of crude protein (82.7 vs. 74.9%) and neutral detergent fibre (41.9 vs. 29.4%). Nitrogen utilization improved with reduced faecal excretion in probiotics-supplemented groups. Probiotics had non-significant effect on carcass traits and fatty acid profile (P > .05). Thus L. acidophilus supplementation enhanced digestibility and utilization of nutrients, weight gain and feed conversion ratio with no negative effect on carcass traits and fatty acid profile.
