A total of 96 Shaver 579 laying hens of 78 weeks of age were studied for the effects on egg production of dietary supplementation with spirulina (Spirulina platensis). The hens were divided into four dietary treatments with six replications of four birds in each group. Birds of three groups were supplemented with 0.1%, 0.2% and 0.3% spirulina and one group was kept as control. Yolk colour significantly improved (P<0.01) as compared to control, without affecting any other production performances. It is suggested that dietary supplementation of spirulina at 0.2 to 0.3% levels in aged laying hens enhanced egg yolk colour. Bangl. vet. 2017. Vol. 34, No. 2, 71-78

The objective of this study was to compare the effects of feed supplementation of laying hens with manganese from its inorganic and organic sources on performance and some parameters of egg quality. Ninety-six hens at 20 weeks of age were randomly allocated to 4 dietary treatments, each consisting of 6 replicates (4 birds per replicate). The control group was fed unsupplemented basal diet (BD) with only natural background Mn level of 46.4 mg/kg feed. For the three experimental treatments, the BD was supplemented with 120 mg Mn/kg either from Mn-sulphate or Mn-chelate of protein hydrolysate (Mn-Pro) or Mn-chelate of glycine hydrate (Mn-Gly). After 8 weeks of dietary treatments the egg production, egg weight, feed intake, and feed efficiency were not affected by dietary treatments. Regardless of the sources, Mn supplementation to feed resulted in significantly decreased percentages of cracked eggs compared to the unsupplemented control group. The thickness, weight, proportion, and index of eggshell were significantly elevated in all groups supplemented with Mn. The intake of Mn-Gly resulted in considerably increased Mn deposition in egg yolk compared to the control eggs. In the control and Mn-sulphate groups yolk malondialdehyde (MDA) started to increase after 20 and 30 days of egg storage respectively, whereas in eggs from hens given organic Mn-sources this parameter was not affected up to 40 days. Although there were no significant differences in MDA values between the treatments until 20 days of storage, the Mn-sulphate group showed significantly higher MDA concentration in yolks compared to the control group after 30 days of storage. These results demonstrate that supplementation of hens&rsquo; diet with Mn has positive effects on eggshell quality. Feed supplementation with Mn from organic sources appears to be more effective in preventing yolk lipid oxidation during cold storage of eggs than that from Mn-sulphate. &nbsp;

The present study evaluated the effects of dietary supplementation of chitooligosaccharide (COS) on egg production, egg quality and blood profiles in laying hens. A total of 192 Hy-Line Brown laying hens (initial age- 46 weeks) were allocated to one of four treatments with eight replications per treatment and six adjacent cages as replication for eight-weeks study. Dietary treatments consisted of CON, basal diet; COS1, CON + 0.1% COS; COS2, CON + 0.2% COS; and COS3, CON + 0.3% COS. Linear improvement (p Lass Than 0.05) was observed in egg quality and high-density lipoprotein cholesterol (HDL/C) concentration at subsequent weeks. In week 8, linear (P=0.04) improvement was observed in haugh unit of egg with the increase in the dose of COS. In addition, linear effects (p Lass Than 0.05) on eggshell thickness at week 3, 5, 6, 7 and 8 were detected as the level for increased COS. In conclusion, the supplementation of COS in laying hens diets linearly improved the egg quality and the HDL/C concentration. Thus, COS has the potential to be used as a substitute to antibiotics in layer hen’s diets.

This study examined the effects of Mentha arvensis (MA) and Geranium thunbergii (GT) extracts in drinking water on the production performance, egg quality, cholesterol content of egg yolk, proximate composition, and sensory qualities of egg and immunity parameters in laying hens. Ninety-six 28-week-old Hy-Line Brown layers were randomly divided into four dietary treatments for 16 weeks. The dietary treatments were (1) control, (2) T1 (0.01% 1 MA:1 GT), (3) T2 (0.05% 1 MA:1 GT), and (4) T3 (0.1% 1 MA:1 GT). Egg production increased significantly with increasing levels of MA and GT. The egg weight was increased in T2, and the feed intake was highest in T2 and T3 (p < 0.05). The Haugh unit and egg shape index were significantly better in T3 and the control than with other treatments (p < 0.05). The content of yolk cholesterol was significantly lower (p < 0.05) in T2 and T3. On the other hand, there were no significant differences in the egg proximate composition. A significant increase in the serum interleukin 6 (IL-6), tumor necrosis factor (TNFα) and immunoglobulins (IgG and IgA) concentration was observed in the birds fed plant extracts when compared to the control. On average, T2 and T3 showed significantly lower (p < 0.05) concentrations of NH3 gas from the feces as compared to the control. This study suggests that MA and GT supplementation could improve the laying performance, egg quality, and immunity, and decrease the egg yolk cholesterol content in a dose-dependent manner.

The aim of this study was to evaluate the influence of the dietary addition of sodium humate (HAS) on performance and immune response of laying hens during peak lay, over an eight-week period. Laying hens, aged 24 weeks old, were randomly allotted to four dietary treatments: a basal control diet or the basal diet supplemented with 0.1, 0.3 or 0.5% HAS. Each treatment had six replicates with 15 layers per replicate. Egg production, egg quality, serum antioxidant parameters and immunity indexes were measured. HAS had no significant effect on egg production or egg and shell quality, but all supplemental levels significantly improved Haugh unit values and egg yolk colour. Supplementation with all levels of HAS significantly increased serum immunoglobuline (Ig) level compared to the hens fed the control diet. Feeding either 0.1 or 0.5% HAS significantly increased serum IgM levels. The results indicated that dietary supplementation with HAS can enhance egg albumin quality and improve immunity in laying hens.

This study aimed to investigate the supplemental effects of fermented pine (Pinus densiflora) needle extract (FPNE) in laying hen diets on productive performance, egg quality, and serum lipid metabolites. A total of 108 40-week-old Hy-line brown laying hens were randomly assigned to one of the three dietary treatment groups: (1) basal diet + 0 mL FPNE/kg diet (CON), (2) basal diet + 2.5 mL FPNE/kg diet (T1), or (3) basal diet + 5 mL FPNE/kg diet (T2) for 6 weeks. Each group consisted of four replicates of nine hens each. Feed and water provided ad libitum. Results showed that dietary supplementation of FPNE increased egg production percentage (linear, p < 0.01 and quadratic, p < 0.05), egg mass (linear, p < 0.05), and feed intake (linear, p < 0.05) during the entire experimental period. In addition, dietary inclusion of FPNE significantly increased the eggshell color (linear, p < 0.01), egg yolk color (quadratic, p < 0.01), and eggshell breaking strength (linear, p < 0.05 and quadratic, p < 0.05) while the Haugh unit decreased (quadratic, p < 0.05). However, serum lipid profile did not differ among the dietary treatments (p > 0.05). Notably, antioxidant activity of egg yolk was improved by significantly decreasing the malondialdehyde content in egg yolks after 6 weeks of storage (linear, p < 0.001 and quadratic, p < 0.05). In summary, dietary inclusion of FPNE could improve laying performance and the antioxidant capacity of eggs.

The purpose of this study was to examine the effect of dietary horsetail (Equisetum arvense) and spirulina (Spirulina platensis) supplementation on performance, egg quality, serum biochemical and antioxidant status of laying hens. A total of 648, 63-week-old Hy-Line W-36 layers were divided into nine groups with eight replicates per group (nine birds per replicate). A feeding trial was conducted under completely randomized design with factorial arrangement 3 × 3 consisting of three different dietary levels of horsetail supplementations (0, 0.25, and 0.50%, respectively) in combination with three levels of spirulina (0, 1, and 2%, respectively). Results showed that feed intake, egg production, egg weight and mass, and feed conversion ratio were not significantly affected by the dietary treatments. Eggshell thickness, strength, and yolk color were significantly improved in diets supplemented with 0.5% horsetail and 2% spirulina and their interactions. Egg yolk cholesterol was not significantly different among groups; however, a significant reduction was found when fed 2% spirulina. Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) concentration decreased by supplementing 2% spirulina in diet; also, spirulina increased total superoxide dismutase (TSOD) and total antioxidant capacity (TAC) in laying hens. Overall, the findings indicated that the combination of horsetail and spirulina could have potential for improving the egg’s physical parameters, whereas spirulina was more effective in improving blood traits and oxidative status.

Dietary Treatments

The practical usage of untraditional feedstuffs such as sunflower meal (SFM) in laying hens nutrition in developing countries has received considerable attention. SFM is a by-product of the sunflower oil industry and has been progressively added to bird’s diets. Sunflower meal (SFM) is gaining great interest as a feed ingredient due to its eminent crude protein content, low anti-nutritional compounds, and low price. The current experiment was aimed to assess the production efficiency, egg quality, yolk fatty acids composition, and nutrient digestibility of laying hens fed SFM. A total of 162 Bovans Brown laying hens aged 60 weeks old were randomly allocated using a completely randomized design into three experimental groups of nine replicates each (n = six/replicate) for eight weeks. The dietary treatments involved a control (basal diet) and two levels of SFM, 50 and 100 g/kg feed. The dietary treatments did not influence live weight gain, feed intake, and egg mass. On one hand, the laying rate was increased; on the other hand, the feed conversion ratio and broken eggs rate of laying hens were decreased (p < 0.05) by the dietary inclusion of SFM. Dietary treatments had no effect on the egg’s quality characteristics except the yolk color and yolk height were larger (p = 0.01) for laying hens fed SFM compared with those fed the control. Dietary inclusion of SFM decreased (p < 0.05) the content of cholesterol in the egg yolk. Still, it increased the yolk contents of vitamin E, calcium, linoleic acid, linolenic acid, and oleic acid (p < 0.05). Furthermore, the dietary inclusion of SFM increased crude protein and calcium digestibility, but decreased the ether extract digestibility. In conclusion, our results suggested that the dietary inclusion of SFM, up to 100 g/kg at a late phase of laying, could improve the production performance, some of the egg quality traits, and nutrient digestibility while decreasing egg yolk cholesterol.

The objective of the experiment was to evaluate effects of dietary supplementation of β-mannanase (Hemicell®) on productive performance, egg quality, and fecal moisture content in laying hens from 20 to 35 weeks of age. A total of 375 Isa Brown’s hens (1615.6 ± 76.4 g/bird) were randomly assigned to 5 treatments in a completely randomized design. The 5 dietary treatments included (1) basal diet with a level of 2800 kcal ME and no β-mannanase supplementation (HE, Control), (2) HE + 32 units of β-mannanase/g of feed, (3) HE + 64 units of β-mannanase/g of feed, (4) basal diet with a level of 2700 kcal ME (LE) + 32 units of β-mannanase/g of feed, and (5) LE + 64 units of β-mannanase/g of feed. Each treatment was replicated with 25 cages of 3 hens each. All diets were in meal form and contained no antibiotics. The addition of β-mannanase to HE diets did not affect the egg production of birds as compared with the control (P > 0.05). The birds fed LE diets with β-mannanase had the same egg production as those fed the control and β-mannanase-supplemented HE diets (P > 0.05). Differences in egg weight, egg quality, survival rate, and fecal moisture content were not significant among the treatments (P > 0.05). Briefly, addition of β-mannanase (32 units/g of feed) to LE diets would be beneficial for layers during the early laying period as it resulted in the same performance and egg quality as the HE diets without β-mannanase supplementation.
