Abstract

This research aims analyze the effect of inoculum dosage of Pleurotus ostreatus and the length of fermentation on the nutritious content of Azolla. The experimental design used completely randomized design in factorial (3 x 3). The first factor is the inoculum dosage, namely : (D1). 3%, (D2).6% and (D3).9% of substrate weight. The second factor is the length of fermentation, namely : (L7). 7 days, (L14). 14 days and (L21). 21 days. Every treatment is repeated for three time. The data found is scrutinized by mode print and it is followed by distance test of multiple Duncan (Steel and Torrie, 1989). The variables observed in research are dry materials, crude fiber, crude protein, cellulose and lignin. The research on the influence of inoculum dosage and the length of fermentation on dry materials content, crude protein and cellulose had not significant effect (P>0.05). On the other hand, crude fiber,and lignin had significant effect (P<0.01). The inoculum dosage of 9% and the fermentation length of 14 days is the best combination treatment and it can reduce the crude fiber amounting to 48.80%, an increase of crude protein amounting to 39.31% and a decrease of cellulose and lignin amounting to 49.86% and 27.66% respectively.

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

The objectives of this experiment were to calculate energy (ME) and crude protein (CP) requirements of Arabic chicken hens in the tropical climates during the early laying period by a choice feeding method. One hundred and thirty-eight of 22-week old Arabic chicken hens were allotted into 12 sheltered pens with 10-14 chicks each. The no free-choice group hens fed a standard diet conforming with the Hy-line Brown Commercial Management Guide, whilst the free-choice group hens fed with a standard diet, an energy-protein rich diet, an energy-rich diet, a protein-rich diet, and an energy-protein poor diet. Feed consumption, energy and protein consumptions, energy (kcal of ME/kg) and protein (g of CP/kg) dietary concentrations were recorded weekly, and egg production was recorded daily. All performance data were taken repeatedly during the first 28 weeks of egg production and were analyzed after summarizing weekly data into seven 28-d periods using the Mixed Procedure in SAS. The dietary treatments had no clear effect on feed and protein consumption but had a significant effect on energy consumption, energy and protein concentrations, and egg production. Energy consumption of the no free-choice group hens was lower than those in the free-choice group hens (1580 vs. 1718 kcal of ME/kg/hen; p<0.05). Energy and protein concentration in the diet of the no free-choice group hens were lower (p<0.01) than those in the free-choice group hens (2814 vs. 3050 kcal of ME/kg and 184 vs. 189 g of CP/kg, respectively). The no free-choice group produced less egg (p<0.01) than those of the free-choice group (56% vs. 61%). Arabic chicken hens consumed more feed from an energy-protein rich diet and an energy-rich diet and consumed less feed from a protein-rich diet and an energy-protein poor diet. Based on the choice feeding, ME and CP requirements for Arabic chicken hens during early egg production were higher than ME and CP contained in the control diet. An average hen day production was higher in the free choice group compared to the control diet group.

Abstract

The present experiment was conducted to estimate the metabolizable energy (ME) and crude protein (CP) requirements of female Arabic chickens under a semi-scavenging system from starter to first egg-laying age. Two hundred and forty-five day-old chicks were allotted into 12 sheltered pens with 20 chicks each. They were offered either control or choice diet and replicated six times. The control group was offered a control diet based on the Hy-line Brown Nutrient Requirements Standard, whereas the choice group was offered a control diet (starter period: 2910 kcal of ME/kg and 19.7% of CP; grower period: 2854 kcal of ME/kg and 17.5% of CP; developer period: 2754 kcal of ME/kg and 16.0% of CP; pre-laying period: 2776 kcal of ME/kg and 16.5% of CP; and laying period: 2814 kcal of ME/kg and 18.4% of CP) together with four other diets (high energy-high protein [3101 kcal of ME/kg and 23.0% of CP], high energy-low protein [3133 kcal of ME/kg and 14.3% of CP, low energy-high protein [2638 kcal of ME/kg and 23.4% of CP], and low energy-low protein [2677 kcal of ME/kg and 14.6% of CP]). Data were analyzed using Proc Mixed of SAS. Results showed that feed intake was significantly lower in choice dietary treatments in all periods, except in the starter period. ME and CP intakes were similar (p>0.05) in all periods. However, ME and CP concentrations in the diet consumed were higher (p<0.05) in choice dietary treatment in all periods, except CP concentration in the starter period. BWG started to be higher (p<0.05) in choice dietary treatment during the developer and pre-laying period. The onset of laying was two days early in choice-fed birds. It can be concluded that free choice feeding on a diet varying in energy and protein had a beneficial effect on the growth rate of female Arabic hens by consuming more a high energy-high protein and a high energy-low protein diet. ME and CP requirements of Arabic hens for starter period were 3026 kcal of ME/kg and 18.8%, for grower period were 3081 kcal of ME/kg and 18.4%, for developer period were 3091 kcal of ME/kg and 18.5%, and for pre-laying period were 3072 kcal of ME/kg and 18.8% to faster the onset of laying.

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
