“…It is well known that the yolk color is depended upon the characteristic of feed. In other study (Chong et al, 2008), PKM decreased the yolk color score with higher level (25%) of supplementation, but no influence with lesser level (12.5%) of supplementation. Therefore, substantially lower (5%) level of PKM supplementation in this study could be a reason why the same PKM did not induce change in yolk color score.…”

“…Therefore, it is believed that the PKM inclusion contributed, in certain extent, for stimulating feed intake in this study. Several laying hen studies (Perez et al, 2000;Chong et al, 2008) reported increased feed intake by PKM inclusion in diets. However, there was a report (Zanu et al, 2012) which showed no difference in feed intake by dietary PKM inclusion.…”

“…Therefore, supplementation of its respective enzyme, mannanase has been recommended (Wu et al, 2005;Sundu et al, 2006). In addition, several poultry studies (Sundu et al, 2006;Chong et al, 2008;Zanu et al, 2012) showed that the appropriate level of PKM inclusion had encouraged the feed intake in laying hens. Therefore, it was hypothesized that the PKM might act as a stimulator of feed intake in the old aged hens.…”

This study was conducted to evaluate the effect of dietary β-mannanase supplementation and palm kernel meal (PKM) inclusion (5%) on laying performance, egg quality and nutrient utilizability of laying hens with 73 weeks of age. A total of 240 Lohmann brown laying hens with average 77.5% egg production were randomly allocated with 60 hens per treatment, 4 replicates per treatment and 15 hens per replicate. Experimental design was a completely randomized design with 2 × 2 factorial arrangement, with the factors being (1) two levels of PKM (0 vs. 5%) and (2) with or without dietary β-mannanase (480 IU/kg of diet CTCzyme ® ) supplementation. All hens were housed in cages (35 cmW × 35 cmD × 40 cmH) with 2 hens per cage for six weeks feeding trial. Laying performance was recorded daily during feeding trial. Egg quality, nutrients utilizability and blood assays were done at the end of feeding trial. Egg production was improved (P<0.05) by both dietary PKM inclusion and β-mannanase combined supplementation. Either β-mannanase or PKM did not affect feed intakes and feed conversion ratio of all diets. Egg weight of hens fed diet containing 5% of PKM had heavier (P<0.05) eggs compared with hens fed without PKM. Albumen height was improved (P<0.05) by dietary mannanase supplementation. Crude fat utilization of 5% PKM diet was higher than that of no PKM diet regardless of β-mannanase supplementation. Both DM and total carbohydrate utilization were decreased (P<0.05) in hens fed 5% PKM diet. Serum IgG and yolk IgY contents of PKM groups were lower (P<0.05) than those of no PKM groups. This result showed that 5% PKM diet, independent of dietary β-mannanase supplementation, was able to improve egg production. In addition, dietary β-mannanase supplementation could be used for improving the albumen height of eggs.

“…The colour of the egg yolk increased significantly (P < 0.05) (Afolabi et al 2012). Chong et al (2008) described the significantly lighter colour of the yolk when extracted palm kernel pomace was added in the feed for laying hens at an amount of 250 g•kg -1 . Supplementation of the feeding dose with 10-100 g•kg -1 linseed cake increased the level of thiocyanate in blood serum.…”

The effect of a diet supplemented with sea-buckthorn pomace on the colour and viscosity of the egg yolk

Sea-buckthorn pomace is a very valuable product which contains not only important nutrients but also high-quality oils. The question addressed in the present study was to what extent the diet containing the sea-buckthorn pomace would affect the viscosity and colour of egg yolk measured in the CIELAB system. The feeding mixture for laying hens was supplemented with 20; 50 and 100 g•kg -1 of sea-buckthorn pomace. As a result, colour indices of the egg yolk such as L*, a* and b* changed significantly (α = 0.01). The greatest relative enhancement was observed for indicator a* for the red colour. Visually, this corresponds to the more intense orange colour of the egg yolk. The addition of sea-buckthorn pomace to the diet for laying hens resulted in a larger increase in indicator ∆E* (CIE total colour difference) compared to the control group. Colour indicator h ab is the only indicator whose value oscillated around that determined for the control group. The addition of sea-buckthorn pomace to the diet resulted in an increase in colour indices a*, b* and C * ab. Indicator ∆E* also increased significantly with an increasing amount of sea-buckthorn pomace in a diet. Egg yolks were darker, had more intense red and yellow colours, and showed lower viscosity which are all features preferred by the consumer.

“…Also in previous studies, enzyme complex supplementation in palm kernel meal diets could improve growth performance in broilers (Chong et al, 2008) and pigs (Ao et al, 2011). Application of a carbohydrase cocktail to facilitate the breakdown of non-starch polysaccharides in 5% palm kernel meal diet could improve the growth performance and energy and nutrient digestibility in finishing pigs (Ao et al, 2011).…”

: This study evaluated whether dietary supplementation of tapioca could alleviate the negative effects of palm kernel meal (PKM) on growth performance and meat quality in growing and finishing pigs. In experiment 1, 120 73-dold crossbred growing pigs [(Yorkshire × Landrace) × Duroc], with an average body weight of 31.7±4.5kg, were used in a 3-week trial. In experiment 2, 120 108-d-old crossbred finishing pigs [(Yorkshire × Landrace) × Duroc], with an average BW of 52.6±4.2kg were used in a 10-week trial. Treatments were: CON, a corn-soybean meal-based diet; PKM, 8% PKM, and TPKM, 8% PKM and 10% tapioca. No difference was observed in growth performance or meat quality among treatments in growing pigs. In finishing pigs, no difference was observed in growth performance or meat quality among CON and TPKM dietary treatments. Finishing pigs fed PKM decreases in final BW and ADG compared with those fed CON. Meat quality was not affected by dietary treatments. In conclusion, dietary supplementation of tapioca alleviated anti-nutritional effect of PKM on growth performance in growing and finishing pigs. Thus, the PKM with tapioca could be an available alternative energy source to reduce the cost of pig diets.
