Effect of Using Corn Distiller's Dried Grains With Solubles in Broiler Diets Without or With Adding Galzym on Growth Performance and Some Physiological Parameters

Abstract

The present study was carried out to investigate the effect of using 10 % and 20 % corn distiller's dried grains with solubles (CDDGS) as partial replacement for yellow corn and soybean meal with or without adding 0.05 % Galzym powder on productive performance, some blood plasma parameters and the immune response of broiler chicks. A total number of 240 day-old, unsexed broiler chicks were randomly assigned to six treatments 40 chicks each. The first group was fed basal (starter and grower-finisher) diets without supplements and considered as control (T1) group, the second group was fed as T1 plus 0.05 % Galzym (T2), the third group was fed 10 % CDDGS (T3), the 4 th group was fed as T3 plus Galzym addition, the 5 th group was fed 20 % CDDGS (T5), the 6 th group was fed as T5 plus Galzym (T6). The obtained results showed that final live body weight values increased by CDDGS replacement. The highest final live body weight, total feed intake and total body weight gain values were recorded by the birds fed 20 % CDDGS level with Galzym as compared to other experimental treatments. Also, the lowest total feed conversion values were recorded for the birds fed 20% CDDGS plus Galzym as compared to other experimental birds. The results showed that there were significant increase in the experimental treatments in plasma total protein and total triglycerides values compared with the control treatment. Moreover, there were insignificant increases in total cholesterol values compared with the control group. Also, there were significant decreases in plasma inorganic phosphorus values as compared to the control treatment. The specific immunity against avian influenza disease virus (AIDV) titer was significantly increased when using 10 % CDDGS with Galzym supplementation in the diets after vaccination as compared to other experimental samples. Also, there were insignificant differences in the Newcastle disease virus (NDV) titer after vaccination among all the experimental treatments. It is concluded that using CDDGS up to 20% in broiler diets as partial replacement for yellow corn and soybean meal with or without Galzym supplementation improved growth performance of broiler chicks and enhanced the specific immunity against avian influenza disease virus titer, with no adverse effects on their physiological blood parameters.

Impact of an indigenously produced multi-enzyme complex from Bacillus subtilis KT004404 on growth and blood parameters in broiler chicken

“…The increase in body weight of 37 to 42 days old birds is also an indication of higher feed intake. These results are in agreement with previously conducted studies [ 2 , 31 ]. Feed intake decreases in the birds fed with exogenous enzymes because the nutrient requirement of birds is fulfilled due to enhanced digestibility in birds [ 37 ].…”

“…Arabinoxylans and phytate are anti-nutritional factors hence, the inclusion of enzyme supplements containing xylanase and phytase improve the broiler performance [ 29 , 30 ]. An increase in body weight by the addition of enzymes is also in agreement with numerous previously conducted studies [ 31 , 32 ]. Increase in FCR after the addition of multiple enzymes in the broiler feed indicates improved nutrient utilization [ 33 ].…”

Effect of Adding Citric Acid (Ca) to Corn Distillers Dried Grains With Solubles (Ddgs) Diets on Reproductive and Productive Performance of Rabbits

“…As for DWG, the results showed the same trend of significant (P<0.01) improvement especially with using CA addition in the diets contained DDGs during the whole growing period (5-11 weeks of age) compared to the control group. In this respect, Dorra et al (2013) obtained an increase in final LBW of broiler chicks when corn DDGS (CDDGS) partially replaced yellow corn and soybean meal. The highest values of final LBW and total BWG values were recorded when broilers fed 20% CDDGS level with 0.05% Galzym.…”

“…Thus, in Egypt, DDGS imports have grown in last decade from 81000 MT in 2010 to 158000 MT in 2019 (USDA, 2020). Several attempts have been made, recently, in Egypt to determine the optimal DDGs inclusion levels in the diets of rabbits Hussein and EL Desoky, (2011) and broilers (Dorra et al, 2013) with or without enzymatic and/or organic acids addition to avoid the adverse effects which based mainly on the evaluation of production and economic efficiency of such feed ingredients. Rostamzad et al (2011) considered CA as a growth promoter, acidifier, bacterial inhibitor, antioxidant and antitoxin.…”
