“…The results suggested that 1X enzyme concentration provided efficient degradation of diet with 6% fiber, which in turn made ample availability of bind nutrients, helpful for the production of eggs. The results of the present study were in inconsistent with the findings of [8,10,18,21,22]. They reported nonsignificant effect of enzyme supplementation on the egg production of the layers.…”

“…Enzymes addition is reported to increase hen day production (%) and egg weight from age of 31st week to 66th week with low ME diet and with high ME diet [10] In old age, layers birds are in downswing of their production curve. During this period the feed intake of the birds remains constant while the egg production decreases which results in decreased profitability/bird.…”

One hundred and twenty white leghorn layers of 80 weeks having uniform body weight were randomly divided into 15 experimental units of 8 birds each and reared under standard managemental conditions. Five treatments (each having three replicates) i.e. control T1 (commercial layer mash), T2 (layer mash having 6% fiber + 1X enzyme), T3 (layer mash having 8% fiber + 1X enzyme), T4 (layer mash having 6% fiber + 2X enzyme) and T5 (layer mash having 8% fiber + 2X enzyme) were randomly allotted to experimental units. Egg production, egg weight and feed consumption were recorded for eight weeks. Egg mass, feed conversion ratio/dozen egg and feed conversion ration/kg egg mass was also calculated. Data was analyzed statistically using analysis of variance technique under completely randomized design. Treatment means were compared using least significant test. It was found that egg production increased significantly by the T2 but was non-significant with the control group. The different treatments showed significant decrease in feed consumption as compared with control group. Significant improvement in egg mass was found in control group and was non-significant with T2 and T4. There was significant effect of enzyme supplementation on feed conversion ration/dozen egg and feed conversion ratio/kg egg mass. T2 and T4 showed best feed conversion ratios per dozen and per kg egg mass. Maximum profit/bird was observed in T2 followed by T4, T5, T3 and T1, respectively.

“…Currently, in a study increasing palm kernel meal to 30% resulted in increased Lactobacillus spp. and reduced coliform/ Escherichia coli counts (p≤0.005), and lower (p≤0.05) excreta pH [ 24 ]. This effect can cause some beneficial effects on performance of digestive system in birds and might be attributed to prevention of pathogens from colonizing in digestive tract via competitive exclusion [ 23 , 25 ].…”

Aim:The aim of this study was the assessment of various levels of date palm kernel (DPK) on the growth performance of broilers.Materials and Methods:A 250-day-old broiler chicks were randomly selected and categorized into five groups (50 chicks/group) contained A (control), B, C, D and E fed with 0%, 1%, 2%, 3% and 4% levels of DPK in balanced ration, respectively, for 6 weeks. Feed and water intake were recorded daily in the morning and evening. The data for feed intake, water intake, live body weight, and feed conversion ratio (FCR) were recorded from all birds regularly. The carcass weight and percentage obtained via six slaughtered birds were randomly selected from each group. Finally, economic aspects of the rations evaluated.Results:The most feed intakes of broilers were recorded in Group A (3915.1 g) that was significantly higher than Groups D and E. The highest water intake was in Group E (9067.78 ml) that was significantly higher than Group A and control group. Live body weight was highest in Group E (979.85 g) than Groups B, C, and control group. The best growth weights were determined significantly in Groups D (1921.96 g) and E (1935.95 g). The lowest FCRs were indicated significantly in Groups D (1.97 g/g) and E (1.92 g/g) than Groups B and A. The highest carcass weights were recorded in Groups D (1214.01 g) and E (1230.88 g) that were significantly more than other groups. Dressing percentages in Groups D (61.76%) and E (62.17%) were higher than other groups (p<0.05). The net profits (Rs.) in Groups A, B, C, D and E were indicated 27.01, 32.77, 36.78, 43.47 and 44.51 per broiler, respectively.Conclusion:It was concluded that the high levels of DPK (3-4%) significantly decreased broiler feed intake and increased water intake, live body weight, growth weight, carcass weight, dressing percentage, net profit per bird and also had positive effects on growth of broilers.

“…PKC has been widely studied for use as a source of protein and energy in both laying hens and broiler chickens. It has been suggested that the incorporation of PKC in broiler or laying hen rations at the optimal level of 20%-30% as a partial replacement for corn and soyabeans results in a reduction in the cost of poultry feed (Alimon and Wan Zahari, 2012;Yusrizal et al, 2013;Chen et al, 2015). Mohamed et al (2012) suggested that utilisation of PKC as poultry feed ingredient at higher inclusion levels become limited due to its high fibre and shell content.…”

Potential of Feeding Crude Palm Oil and Co-Products of Palm Oil Milling on Laying Hens` Performance and Egg Quality: A Review

Crude palm oil (CPO) and the main co-products of palm oil milling, namely palm kernel cake (PKC) and palm oil mill effluent (POME) have considerable potential nutritive value for laying hens. This review was conducted to study the effect of CPO, PKC and POME as feed ingredients on growth performance of laying hens and egg quality traits. CPO provides high caloric levels, and its inclusion in laying rations enhances the absorption of oil-soluble vitamins. High carotenoids (500-700 ppm) content in CPO improves egg quality by increasing the fatty acid content and colour intensity of egg yolk. Laying hens can tolerate up to 20%-30% PKC in the diet with no adverse effects on growth performance or egg quality traits. POME can be used as a feed ingredient for laying hens, and the recommended optimal level of inclusion is 10% of the total ration. However, due to high levels of fibrous matter in PKC and POME, further biotechnology treatments are needed for better utilisation in laying hens' rations to yield optimum egg production.
