| Abstract |
A total of forty eight male New Zealand White rabbits (NZW) of 6 weeks of age with an average initial body weight 785 ±28.3g were used to study the effects of Biogen supplementation on growth performance, digestibility of nutrients, chemical composition of soft and hard feces, carcass traits, constituents of blood plasma, chemical and physical composition of meat and economical efficiency. Rabbits were distributed into 4 groups of twelve rabbits each. Diet 1 served as control, while diets B1, B2 and B3 were supplemented with 0.1, 0.15 and 0.2% Biogen, respectively. Results obtained up to 14 weeks of age showed that the final body weight, daily weight gain and performance index increased significantly (P< 0.05 or 0.01) in groups fed diets supplemented with Biogen especially diets B2 and B3. Also Biogen supplementation showed better (P<0.01) feed conversion than the control group. Digestibility values and feeding values as TDN, DCP and ME were significantly higher (P< 0.05 or 0.01) with Biogen supplementation diets (0.15 and 0.2% ) than with the control group. Rabbits fed diets supplemented with 0.15 and 0.2% Biogen execrated higher crude protein in soft feces and lower in hared feces. Crude fiber content of soft and hard feces was the lowest ( P<0.05) in groups supplemented with 0.15 and 0.2% Biogen. Carcass traits was insignificantly affected with Biogen dietary supplementation, expect dressing %, hot and cold weight. The dietary supplementation with Biogen significantly (P<0.01) increased protein % and water holding capacity of rabbit meat. While the tenderness was insignificantly increased. The energy value of the rabbit meat was decreased ( P<0.01) in groups fed diets supplemented with Biogen. The highest economical efficiency value was recorded in group fed diet B2 supplemented with 15% Biogen.
Keywords: Biogen, probiotics, growth promoters, rabbit performance, digestibility, carcass, serum constituents.
