Abstract

Eighty weaned Alexandria line male rabbits, about 5 weeks old with an average body weight of 575.4±85.7 g, were randomly distributed into four experimental groups of 20 rabbits each and 5 replicates per treatment (4 rabbits each), fed a basal diet and drinking tab water without additives (Control rabbits, C); 2nd (T1), 3rd (T2), and 4th (T3) groups received drinking tab water supplemented with different probiotic sources  at  1 ml of Grow star, 0.5 ml of FIDAL, and 1 ml of effective micro-organisms (EM1) of the additives mixture per liter, respectively. Experimental period was lasted for 5 weeks until 10 weeks of age. These results showed that a significant increase in body weight and body weight gain of T2 and T3, while feed intake was a significantly increased in T3 as compared to other groups. However, feed conversion ratio mathematically decreased in T1 and T2 groups, while performance index mathematically improved in T2 and T3. Carcass traits and different parts of carcass did not affected by treatments, except head as % and shoulders as %, where those were decreased significantly (P≤0.05) in T2 and T3 groups when compared to control group. Plasma levels of calcium and phosphorus concentrations were higher of rabbits given Grow Star (T1) group than other group's rabbits. Ileum and caecum were more developed in the T3 group, as noted by increasing villi height and the thickness of the tunica muscular and serosa layer. Also, the number of caecal crypt glands was increased significantly in T3 compared to other treatments. Rabbits received FIDAL 0.5 ml or EM1 1 ml/liter of drinking water had significantly (P≤0.05) higher economic efficiency in compared to other groups. Conclusively,  from these results it could be  concluded that using 0.5 ml/l FIDAL or 1 ml/l of effective micro-organisms (EM1) as a water supplementation in rabbits drinking water can be improve productive performance and increase feed utilization without any negative effect on carcass traits and achieve good relative economic efficiency, during summer season. Using Grow Star 1 ml/l of drinking water improved FCR and increased calcium and phosphorus in plasma.
