| Abstract |
This study was conducted to investigate the effect of feeding diets supplemented with seaweed (Ulva lactuca or Gntromorpha intestinalis) on growth performance and some blood hematological and biochemical characteristics of male Baladi rabbits. Eighteen Baladi rabbits at 2 months of age were used and allotted randomly into 3 groups of six animals for each. The initial average live body weight values were 800, 850 and 820 g for the control group, Ulva lactuca group (T1) and Gntromorpha intestinalis group (T2), respectively. Experiment lasted for 120 days. Results indicated that rabbit group fed on Ulva lactuca gained more weight than the control group followed by the Gntromorpha intestinalis group. The control group had more intake than the tested groups. Ulva lactuca group (T1) and Gntromorpha intestinalis group (T2), had significant (P<0.05) increases in digestibility coefficients, nutritive values and metabolizable energy (ME) values compared to the control animals. Ulva lactuca (T1) group achieved the best of both economical efficiency and relative economic efficiency (79.19 and 144.90 %), respectively compared to T2 and control groups.
At the end of the treatment (4 months), all animals were sacrificed and blood was collected for further hematological and biochemical studies. Overall means of red blood cells (RBCs) and hemoglobin (Hb), total protein, albumin, globulin, triglycerides, HDL, LDL, LDH, TBL were not significantly different between animal groups, while white blood cells (WBCs), plasma glucose, total lipids, cholesterol, very low density lipoprotein (VLDL), urea, creatinine, Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and direct bilirubin (DBL), indirect bilirubin (IBL) were significantly (at P<0.05 or P<0.01) different between animal groups. Results revealed that white blood cells (WBCs), total lipids, and indirect bilirubin were significantly (P<0.05) decreased by treatments. On the other hand, significant (P<0.01) increases were found in glucose, total lipids (T1), cholesterol, VLDL, urea, creatinine, AST and ALT enzymes, DBL (T2) in the treated animals than those in control animals, while, other parameters were not significantly affected by seaweed treatment.
So it can be concluded that dietary seaweed particularly Ulva lactuca has positive effect on the productive performances of the growing Baladi rabbits. The hematological and biochemical parameters investigated in this study did not reveal any signs of illness in rabbits due to consumption of rations contained 1% seaweed of their content.
Key words: Seaweed, growing rabbits, digestibility, nutritive value, biochemical parameters.
