Abstract

Objective: This study investigated the effects of probiotics- Progut® (PG) and/or canola seed (CS), canola meal (CM), and canola oil (CO) on the growth performance, blood components, antioxidant status, and immune response in rabbits.

Design: Randomized controlled study.

Animals: One hundred and twenty rabbits were used.

Procedures: Rabbits were assigned into 8 groups: control non supplemented group and the other supplemented groups including; PG, CS , CS+PG , CM, CM+PG, CO, and CO+PG. Growth performance, liver and kidney biomarkers, lipid profile, antioxidant markers, and immunological parameters were determined at the end of the study.

Results:. CM and CO had the strongest impact on growth performance, as they significantly increased body weight gain and reduced feed intake. PG significantly increased IgM and NO levels and decreased cholesterol level. CS and CM significantly increased leukocyte count , total protein and globulin levels. Additionally, CS increased serum lysozyme activity, whereas CM increased the hepatic GSH levels. CO increased (P < 0.05) the values of total protein, globulin, SOD, GSH, and lysozyme and significantly diminished MDA.

Conclusion and clinical relevance: Supplementation of CS with PG is recommended to obtain good outcomes on rabbits general health, immunity, and performance without adverse effects on lipogram.
