ABSTRACT

A 60-day experiment was carried out at Sumitra Research Institute in Gujarat to investigate the effect of dietary supplementation with Ocotea aciphylla essential oil on weaned rabbit growth performance and nutrient digestibility. The experiment used 50 weaned cross-bred male rabbits. The animals were acclimatized for two weeks and fed a basal diet that was adequate in all nutrients based on their requirements. Then, their body weights were equalized and randomly assigned to five treatments, each with ten rabbits. Every treatment has ten replicates, with one animal per replicate. Animals in treatment 1 were fed basal diet without Ocotea aciphylla oil, treatment 2, 3, 4 and 5 were fed same diet supplemented with Ocotea aciphylla oil at 0.1 mL, 0.2 mL, 0.3 mL and 0.4 mL/kg diet. The main chemicals found in Ocotea aciphylla oil were α-pinene (22.60%), α-cymene (12.41%), α-terpinene (10.45%), myrcene (7.53%), α-thujene (6.05%), and limonene (5.10%). The other chemicals obtained were less than 5.00%. The treatment had a significant (P<0.05) effect on the average daily weight increase and feed intake values, which ranged from 19.86 to 26.40 g and 100.3 to 106.9 g, respectively. Dietary supplements improved FCR compared to control, with just 1.20% mortality among rabbits on diet 1 (P<0.05). The nutrient digestibility of dry matter (68.14 - 77.81%), crude protein (59.07 - 68.19%), crude fiber (35.62 - 40.41%), ether extract (47.35 - 50.73%), and nitrogen free extracts (49.18 - 59.94%) varied considerably (P < 0.05) across treatments. Finally, Ocotea aciphylla essential oil can be added to the food of weaned rabbits at a dose of up to 0.4 mL/kg without impairing animal performance.
