“…Maize is one of the most important ingredients of laying hens fed contains lutein, zeaxanthin, which are the main xanthophylls in egg yolks (NRC, 1994). Shin et al (2015) reported that maize contained a high amount of lutein (2,096 μg/100g). Minatel et al (2014) reported that rice contained amount of lutein (243.7 μg/100g).…”

“…Minatel et al (2014) reported that rice contained amount of lutein (243.7 μg/100g). Pigmentation of egg yolks is influenced mostly by layer diet (Colin et al, 2004) and maize is a rich source of xanthophylls (Shin et al, 2015). Natural xanthophylls is well-absorbed by hen intestinal cells (Gouveia et al, 1996) and is transferred to the yolk (Donald and William, 2002) after being released into the circulatory system (Salma et al, 2007).…”

This study aimed of effects of replacing maize with rice or brown rice on laying performance, egg quality, and apparent fecal digestibility of nutrient in Hy-Line Brown laying hens. A total of 200, 25-week old Hy-Line Brown laying hens were randomly assigned to one of 5 treatments, each of which was replicated 4 times. Four experimental diets that were formulated two different grains (brown rice or rice) with two inclusion levels of (15 and 30%) as a replacement of maize. The experimental period was 8 weeks. During the experiment, hens were provided with feed and water ad libitum and were exposed to a 16:8=L:D lighting schedule. There were no differences in feed intake, egg weight, and egg mass during the 8 weeks of the feeding trial among groups. However, hen-day egg production was greater (P<0.05) for Brown rice treatment groups than that for basal and rice treatment groups. In addition, the supplementation of brown rice or rice did not have an effect on eggshell strength, eggshell thickness, and HU during of the feeding trial (Table 4). However, egg yolk color was less (P<0.05) for basal treatment groups than that for among treatment group. ATTD of dry matter (DM) and crude fat were greater (P<0.05) for brown rice 15 treatment than for rice 30 treatment. Crude protein (CP) was greater (P<0.05) for brown rice 15 treatment than for basal treatment. In conclusion, brown rice or rice grains is a good alternative energy feedstuff and can be used in laying hens, totally replacing maize, without any negative effect on the laying performance, egg quality, and nutrient digestibility.

“…The extent of yellowness in egg yolk color is known to be largely dependent on the concentration and type of dietary colorants (e.g., xanthophyll) [35,36]. Therefore, our observation for decreased egg yolk color by feeding diets containing supplemental fat is likely a consequence of replacing corn grains and corn gluten meal, which contain high amounts of egg yolk colorants, with supplemental fat.…”

Objective This experiment aimed to investigate the effect of different sources and inclusion levels of dietary fat on productive performance and egg quality in laying hens raised under hot environmental conditions. Methods A total of 480 Hy-Line Brown laying hens at 31 wk of age were randomly allotted to 1 of 5 experimental diets. The control diet contained 2,800 kcal/kg nitrogen-corrected apparent metabolizable energy with no fat addition. Four additional diets were prepared by adding 2.0% or 4.0% of animal fat (AF) or soybean oil (SO). Energy and nutrient concentrations were consistent among all diets. Diets were fed to hens for 4 weeks. Average daily room temperature and humidity were 26.7°C±1.52°C and 77.4%±4.50%. The heat stress index was approximately 76, indicating that hens were raised under heat stress conditions. Results Final body weight (BW) was greater (p<0.05) for hens fed diets containing 2.0% or 4.0% AF than for those fed the control diet or diets containing 2.0% or 4.0% SO. The BW gain and feed intake were greater (p<0.05) for hens fed diets containing additional AF or SO than those fed the control diet. Eggshell thickness was the greatest (p<0.05) for hens fed the control diet, but the least (p<0.05) for hens fed diets containing 4.0% SO. Egg yolk color was the greatest (p<0.05) for hens fed the control diet, but the least (p<0.05) for hens fed diets containing 4.0% SO. Conclusion Inclusion of supplemental fat (AF and SO) in diets exhibits preventative effects on BW loss for hens raised under hot environmental conditions when energy and nutrient concentrations in diets were maintained. The effects were greater for AF than for SO. However, inclusion of supplemental fat in diets decreases eggshell thickness and egg yolk yellowness, possibly due to a reduction in Ca absorption and intake of egg yolk colorants.

“…Detailed procedures for data collection of productive performance and egg quality have been demonstrated previously [ 14 , 15 ]. In short, laying performance including hen-d egg production, egg weight, egg mass, and soft and broken egg production was recorded daily, whereas feed intake and feed conversion ratio (FCR) were recorded weekly.…”

“…Egg quality was measured with four eggs randomly collected from each replicate at the end of the experiment [ 15 ]. Eggshell color was determined using the eggshell color fan (Samyangsa, Kangwon-do, Republic of Korea; 15 = very dark brown and 1 = very light and pale).…”

ObjectiveThe objective of this experiment was to investigate the effect of dietary β-mannanase on productive performance, egg quality, and utilization of dietary energy and nutrients in aged laying hens raised under hot climatic conditions.MethodsA total of 320 84-wk-old Hy-line Brown aged laying hens were allotted to one of four treatments with eight replicates in a completely randomized design. Two dietary treatments with high energy (HE; 2,800 kcal/kg nitrogen-corrected apparent metabolizable energy [AMEn]) and low energy (LE; 2,700 kcal/kg AMEn) were formulated. Two additional diets were prepared by adding 0.04% (MN4) or 0.08% β-mannanase (MN8) to LE treatment diets. The feeding trial was conducted for 28 d, covering a period from July to August in South Korea. The average daily room temperature and relative humidity were 29.2°C and 83%, respectively.ResultsProductive performance, egg quality, and cloacal temperature were not influenced by dietary treatments. The measured AMEn values for MN8 diets were similar to those for HE diets, which were greater (p<0.05) than those for LE and MN4 diets. However, the AMEn values for MN8 diets did not differ from those for LE and MN4 diets.ConclusionThe addition of β-mannanase to low energy diets increases energy values for diets fed to aged laying hens. However, this increase has little positive impacts on performance and egg quality. These results indicate that dietary β-mannanase does not mitigate the heat stress of aged laying hens raised under hot climatic conditions.
