Effect of feed additive "Exogenous Enzymes" on growth performance of Maghraby Camels

This experiment aimed to evaluate the effects of a mixture of exogenous enzymes (ZADO (R)) from anaerobic bacteria on growth performance, feed intake, nutrient digestibility and blood parameters. Eighteen growing Maghraby camels averaged, 268.83 kg body weight; 1.5-2 years. Camels were randomly divided into 3 equal groups (6 in each) of similar weight and age, which were offered complete rations with tow levels of ZADO (R) product. The first group was Zero g/h/d (control), the second group take 20 g/h/d of ZADO (R) and the third group 40 g/h/d, over a period of 90 days. Results indicated that 40 g supplementation showed the best response in DM and OM digestibility. Carbohydrate results showed significantly effects of ZADO (R) supplementation on crude fiber and Nitrogen free extract in R40 being, 78.23 %, 80.60% and R20 being, 75.56%, 77.23%, respectively with insignificant difference between R20 and C ration. NDF digestibility was significantly with R40 (75.77%) followed by R20 (72.99%) and C (71.17 %). Blood parameters of control and tested groups of camels were in normal range with slight decrease in total lipid. Total body gain and average daily gain (ADG) significantly differed among experimental groups being 61.87, 84.82 and 88.65 kg and 0.69, 0.94 and 0.98, in C, R20 and R40 kg, respectively. Data related to feed intake as DM, TDN showed insignificant difference among groups of camels. It could be concluded that growing male Maghraby camels fed on the diet containing ZADO (R) performed better than those offered the control ration. Moreover, adding ZADO (R) in camel ration (40g/h/d) was the better, as confirmed by the highest body weight gain, most of blood metabolites and digestibility. [Adel E. M. and Hassan EL-Metwaly.
