The experiment consisted of two sub-trials, conducted to assess the productivity of broiler chickens fed on the different level of PKC (palm Kernel cake) diet, and growth responses of broilers fed the diets based on pellet and mash form. In main trial, a total of 175 day old male chicks (Cobb500) was randomly distributed into 7 dietary treatments [D1, D2, D3(10%), D4(15%), D5(20%), D6(25%), D7(30%) ], with five replicates and five birds per replicate in a CRD. Birds were fed commercial starter diet up to 21 days and then finisher or test diet supplemented with PKC was provided the birds ad libitum from 22 to 35d. Results of main trial showed that feed intake (FI), live weight (LW), feed conversion ratio (FCR) and mortality (%) of broilers were unaffected (P>0.05) by feeding commercial diet until 21d. The FI, LW, body weight gain and mortality of broilers fed on test diets were also unaffected (P>0.05) between treatment except for FCR from 22 to 35 d. Birds fed on control (D1& D2) diets had a better (P<0.05) FCR than the birds fed on other diets from 22 to 35d. Results of second sub-trial showed that broilers preferred the pellet (P) diet to the mash (M) diet at 42d, as the FI of broilers was higher (P<0.01) on P than the M diet, with no influence on the LW, FCR and mortality. It can be deduced that PKC can be used successfully up to 30 % in the broiler diet as a cheap source of protein supplement to replace other costly protein sources for poultry production. 1486792959.php
