Nutritional and physiological studies on improving the utilization of wheat bran in laying hen diets
Abstract: A total number of 72 laying hens Matrouh strain of 32 weeks of age were used to study the effect of using wheat bran in laying diets and the possibility to improve feeding value of wheat bran 'when supplemented with some feed additives. Hens were housed in individual cages and were randomly divided into six equal treatments (12 birds each) and were approximately similar in body weight. Treatment 1 was received the control diet contained 16% CP and 2703 kcal ME/Kg. Treatment 2 was received the basal wheat bran diet(WB-diet) contained 16.01 % CP and 2111 Kcal ME/Kg. Treatments 3,4,5 and 6 were received the WB-diet supplemented with 1.0% sodium sulphate (SS). 0.1% kemzyme (KE) . 1.0% SS plus 0.1% KE. or 0.1% KE plus 1.0% Radish. extract (RE) . respectively. Birds were fed the experimental dietsfor three months . Results showed that WB-diet significantaly reduced .feed intake with no detrimental effect could be found on feed conversion or egg quality. Addition of SS. KE. KE+SS. and KE+RE improved feed conversion by 19.58. 29.72. 21.64. and. 7.53%, respectively compared to hens fed WB-diet without additives. Also, feed additives improved egg weight and egg mass. Addition of KE+SS or KE+RE improved digestion coefficients of CP, CF, NFE and appearent ME. Addition of SS or KE+SS significanltly increased the level of calcium in serum. WB-diet decreased significantly yolk cholesterol. It could be concluded that WB can be used up to 35%in Matrouh laying hen diets, also it can be used Kemzyme sodium sulphate. Kemzyme plus sodium sulphate or Kemzyme plus rad. . extract to improve egg number, egg weight and feed conversion.
