The Effect of Dried Chicory Root Added to the Restrictive Feed Ration of Rabbits on Health Status, Performance and Caecal and Carcass Traits

Popis výsledku v původním jazyce

Two experiments were carried out to analyse the effect of the addition of chicory roots to the restrictive feed ration on growth, caecal and carcass traits, and sanitary risk index (SRI). A total of 180 Hyplus rabbits (28 d of age; Experiment I) were randomly allocated to one of 3 groups (AL, R, and RC; 60 rabbits per group; 5 rabbits per cage) and fed a standard weaning diet. AL rabbits were fed ad libitum between 28 and 70 d of age; R rabbits were restrictively fed from 28 to 42 d of age (70% of the AL group), and then fed at a level of 80% of the AL group for 3 days before being fed ad libitum until 70 d of age; RC rabbits were offered the restrictive feed ration (70, 80 and 90% of the AL rabbits from 28 to 49, 49 to 56 and 56 to 63 d of age, respectively) with the addition of dried chicory root. Afterwards, RC rabbits were fed ad libitum without the addition of chicory root until 70 days of age. In addition, 30 additional Hyplus rabbits (28 d of age) were randomly allocated to one of 3 groups (AL, R, and RC; 10 rabbits per group; individually housed; sacrificed at 49 d of age) and used to assess the caecal traits. A total of 240 Hyplus rabbits (36 d of age; Experiment II) were randomly allocated to 2 groups (AL and RC; 120 rabbits per group; 5 rabbits per cage) and fed the above-mentioned diet. AL rabbits were fed ad libitum between 36 and 78 d of age; RC rabbits were offered the restrictive feed ration (70, 80 and 90% of the AL group from 36 to 57, 57 to 64 and 64 to 71 d of age, respectively) with the addition of dried chicory root. Afterwards, RC rabbits were fed ad libitum without the addition of chicory root until 78 days of age. In R rabbits, the caecal pH was higher (+0.3 unit) and total VFA concentration lower (-47 umol/g, P<0.05) than in AL rabbits.
