Abstract: The purpose of the present study is to investigate the effect of different additive supplementations on weaning rabbits, given individually or in a combination, on growth performance, carcass traits, some blood biochemical parameters and cecum microflora. One hundred and sixty weaned New-Zealand White rabbits (NZW), at 5 week of age, weighing an average of 653g, were divided into equal eight groups ( 20/ each), Rabbits in group one received basal diet. Rabbits of groups 2, 3, 4 received diet supplemented with sodium gluconate (SG) 4g/kg diet, mannan 1g/kg diet or potassium diformate (KDF) at 4.5 g/kg diet, respectively. While, rabbits of groups 5, 6, 7 and 8 received diet supplemented with a combination of (SG+MOS), (SG+KDF), (MOS+KDF) and (SG+MOS+KDF), respectively. The rabbits houses were made of available local materials (mud, wood etc...,). Rabbits were fed ad libitum on pelleted ration contain 17.7% Crude protein, 2531 kcal/kg Metabolizable energy (ME), 12.7% Crude fiber. The study was conducted during fattening period (5-13 weeks of age) from April to June 2012.
The results showed that supplementation with additives, individually or in mixture, significantly increased e marketing body weight and body weight gain compared to the controls. However, feed conversion improved in all treated groups. Feed intake was insignificantly increased in all treated groups. Carcass traits was improved significantly in all treated groups. Hemoglobin concentrations, white blood cells counts, albumin, aspartate aminotransferase and alanine aminotransferase increased significantly in all treated groups compared to the control group. Hematocrit values, total protein and creatinine increased insignificantly in all treated groups compared to the control groups. Significant reduction was observed in blood pH and urea nitrogen compared to the control. Count of E.coli, total anaerobic bacteria, cecum pH and ammonia concentration significantly decreased in all treated groups compared to the control. However, lactobacilli account and total volatile acids were significantly increased while mortality rate decreased in all treated groups. Economical efficiency improved in groups received the additives.
It was concluded that using of sodium gluocnate, mannan and potassium diformate ,either separate or in combination, in diet of weaning rabbits had beneficial effects throughout the growing period such as decreased in cecum microflora, improved hematological parameters and productive traits.
Key words: sodium gluconate, mannan, potassium diformate, rabbit performance
