Abstract
The objective of the present study is to investigate the impact of dietary probiotic administration on growth parameters, carcass parameters, serum biochemical constituents and immune responsiveness in growing rabbits. A total number of 54 rabbits aged 4 weeks were allocated randomly into three experimental treatments with levels of dietary probiotic (0, 1 and 2%). The probiotic containing 2.67 x 1011 CFU/g of Bacillus licheniformis. There were 9 replicates of each dietary treatment with 2 rabbits each. Dietary probiotic had no significant effect on body weight gain, feed conversion ratio, carcass % and carcass parts percentages including front%, mid%, hind %, skin %, and head%. Also, dietary probiotic supplementation had no significant impact on internal organs including heart, testes, lunges, kidney and thymus, while liver % was reduced due to dietary 2% probiotic in growing rabbits. Probiotic supplementation had insignificant impacts on all blood biochemical traits including total protein, albumin, globulin, cholesterol, triglycerides and urea in fattening rabbits. Dietary probiotic supplementation had a beneficial impact on cell-mediated immunity at 24 h post-injection of phytohemagglutinin P (PHA-P) into the left ear in growing rabbits. It could be concluded that dietary probiotic had a positive impact on cell-mediated immunity, while growth parameters, carcass traits, and serum biochemical constituents were not affected.
