Abstract

The present study aimed to estimate the metabolizable energy (ME) and protein (CP) requirements of Arabic chicken hens during the late egg production period reared under a semi-scavenging system with free-choice feeding. A total of 112 sixty-two-week-old Arabic chicken hens were used. The treatments were control and the choice diet consisted of 6 replicate pens. Control hens received a control diet (2750 kcal of ME/kg and 14.1% of CP) complying with the Hy-line Brown Commercial Management Guide 2011, whereas the choice hens offered control and three other diets (high energy-high protein [3006 and 17.3], high energy-low protein [3089 and 12.7], and low energy-high protein [2656 and 17.0] kcal of ME/kg and % of CP, respectively). Feed, ME, and CP intake, the concentration of dietary ME and CP, and egg production were recorded weekly. Data were analyzed using Proc Mixed of SAS. The feeding method influenced feed intake, CP concentration, and ME concentration but had no significant effect on CP intake, ME intake, and egg production. Weekly feed intake of choice hens was lower than that of control hens (514.03 vs. 551.18 g /hen/week; P<0.03). Dietary concentrations of ME and CP in the choice hens were higher than those in the control hens (2957 vs. 2750 kcal of ME/kg; P<0.001 and 150.6 vs. 14.1 g of CP/kg; P<0.001). Egg production of the choice hens was not significantly higher than that of the control hens (51.17% vs. 46.82%; P>0.05). Feed intake, CP intake, and ME intake decreased significantly at week 66 onward, while egg production decreased at week 65 onward. It can be concluded that Arabic chicken hens in the late egg production period were able to adjust their energy and protein requirements by consuming more from high dietary energy than from a high dietary protein. Based on the choice feeding, ME and CP requirements for Arabic chicken hens during the late egg production period in the semi-scavenging system were 2957 kcal/kg and 151 g/kg and higher than ME and CP contain in the control diet of 2750 kcal/kg and 141 g/kg to maintain egg production. The egg mass and feed conversion ratio were better in the choice hens group.

Abstract

This study aims to utilize a sufficient amount of palm kernel cake (PKC) and buffalo rumen fluid as a source of enzymes to improve the quality of PKC that can be used in broiler feed. The study was conducted in two stages. The first stage was to test the level of buffalo rumen fluid enzyme at various doses (0.0%, 0.75%, 1.5%, 2.25%, and 3.0% (v/w) in PKC incubation to measure dry matter (DM), organic matter (OM), crude fiber (CF), and dissolved glucose total (DGT) contents as hydrolyzed PKC. The second stage was to determine the usage level of hydrolyzed PKC in broiler feed. A total of 288 DOC MB202 strains were randomly allocated to one of five treatments with four replicated cages of 12 birds in a completely randomized design. Treatments were the various level of hydrolyzed PKC as following: 0%, 6%, 12%, 18%, 24%, and 30%. The variables were feed consumption, body weight gain (BWG), feed conversion ratio (FCR), final body weight (FBW), carcass, and digestive organs weight. The level of buffalo rumen fluid enzymes had a significant effect on DM, CF, and DGT content, while it was not significant on OM. The optimum level was 2.25% and it was used in the second stage. The use of hydrolyzed PKC up to 18% was not different (P>0.05) in BWG, FCR, and FBW compared to controls. The use of hydrolyzed PKC up to 24% decreased BWG, FCR, and FBW, but feed consumption did not differ (P>0.05) compared to control. Carcass and digestive organ weight were not affected (P>0.05) by the treatment. It can be concluded that the incubated buffalo rumen fluid enzymes at a level of 2.25% could improve the quality of PKC. The use of hydrolyzed PKC could be applied up to 18% without affecting the performance of broilers
