This study was conducted to appraise the effects on egg quality and production performance of laying hens when drinking water was supplemented with calcium (Ca) and magnesium (Mg). A total of 384 (64-week-old) Hy-line Brown laying hens were assigned at random to four treatments, which consisted of CON: unsupplemented drinking water; T1: drinking water + 2 mg/L Ca + 250 mg/L Mg; T2: drinking water + 4 mg/L Ca + 510 mg/L Mg /10 L; and T3: drinking water + 5 mg/L Ca and 760 mg/L Mg. The experiment lasted six weeks. Water intake increased linearly in week 1 with the rising levels of Ca and Mg in the drinking water. Increasing the Ca and Mg levels improved eggshell strength (week 2 (P =0.01), week 5 (P =0.01), and week 6 (P = 0.03), and eggshell thickness (week 6) (P =0.02) and reduced the rate at which eggs were broken (week 4) (P =0.01). The supplemental Ca and Mg did not affect egg production, egg weight, Haugh unit, albumen height, eggshell colour, and yolk colour compared with CON. Nor did they influence the Haugh unit and albumen height after storing for 1, 5, 10 and 15 days. In conclusion, adding Ca and Mg to the drinking water increased the thickness and strength of the eggshells.

The purpose of this study was to determine the effect of Moringa leaf meal (Moringa oleifera) in feed on production performance and egg quality of laying hens. The materials used 120 laying hens of Isa Brown breed in 38 to 42 weeks age. The method used an experimental trial by Moringa oleifera addition in the basal feed. The experiment were devided into four groups i.e. without Moringa oleifera as control (P0), with Moringa oleifera 0.5% (P1), 1% (P2), 1.5% (P3) and 2% (P4). Variables observed were the appearance of egg production and quality. The data was analyzed by Completely Randomized one way design. The mean differences were calculated by the Duncan Multiple Range Test. The results showed that administration of Moringa leaf powder can increase the production and quality of eggs in laying hens. Addition of 2% Moringa leaf powder in the feed gives the best effect on the appearance and quality of production and egg. This research suggested the addition of 2% Moringa leaf powder was recommended in order to obtain the finest appearance and quality of production.

Feed shortage had become a major factor constraining the development of animal husbandry. Forage canola has been found to be a potential feed crop due to its high yield and good quality. Therefore, this study mixed different proportions of forage canola to the diet of laying hens and all eggs were collected for analysis. Laying hens were divided into four groups according to the feeding amount of canola: 0 kg, 3 kg, 6 kg, 9 kg, with 30 laying hens in each group. In the feeding trial, there was no negative effect on hen body weight, egg production, or overall egg quality. The results showed that Group B, C and D complete feed consumption is less than Group A. From the spectrum analysis, the trend of the Group A was different from that of the other three groups. After 35 days of rearing, the laying rate of the Group B and the Group C increased about 30% compared to 1 to 7 day. The weight of the Group B and Group C increased about 5% compared with the initial period, while the Group A increased 0.6% and the Group D increased by 3%. The eggshell strength of the Group B and Group C also increased significantly. The contents of phosphorus and potassium in the Group B and C were higher than those in the Group A and Group D. The effects of canola to poultry diets is therefore of practical interest. This study will provide us a potential forage substance in laying hens production performance. © 2021 Friends Science Publishers

Significant Difference

This study was conducted to know the production performance of laying hen by using different graded level of linseed. At 56 weeks of age, a total of 160 laying hens were raised up to 63 weeks of age. All hens were fed a basal corn soyabean meal diet. The experiment was allowed 4 dietary treatments (T0, no addition of whole linseed in the basal diet; T1,  addition of 5% whole linseed; T2, addition of 10% whole linseed and T3, addition of 15% whole linseed) with 5 replications and per replication contains eight hens. Egg production, feed intake, egg weight of each treatment was recorded. Egg samples were collected and analyzed for egg quality. The results showed that egg production and egg mass (kg) exhibited for all dietary treatment groups were unaffected (P>0.05) by feeding linseed to the laying hens. Feed Conversion Ratio (FCR) was found significant difference within the four dietary group (P<0.05). Egg quality aspects such as yolk weight, egg weight, HU and yolk index were not differed significantly (P>0.05) among treatments.  A trend for lower yolk weight was observed in birds fed 10% linseed, where as the highest yolk weight percentage was recorded in control diet. There was no statistical difference among the different diets for yolk index. The results of the present trial suggested that feeding linseed to the laying hens has no detrimental effects on egg production and egg quality.

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 present study was conducted to find the effect of different levels of organic minerals on egg production and egg quality of laying hens. A total of 45 laying hens were selected and divided into three groups with 3 replicates of 5 birds each. The control group was provided with commercial ration having inorganic minerals and the other two groups were supplemented with organic minerals at the rate of 7.5 (OM-50) and 15 mg/kg (OM-100). The experiment lasted for 5 weeks including 1 week of adaptation period. Overall feed intake was significantly higher (P<0.05) in the control. Significantly lower feed intake was recorded in group OM-100. Numerically lower (better) FCR was recorded in OM-100 at all recorded stages. Significantly (P<0.05) higher egg weight, egg shell weight and egg shell thickness was found in OM-100 compared to the control. Similarly, albumin height, Haugh unit and yolk weight were significantly (P<0.05) higher in M-100. It was concluded from the present results that organic minerals at the level of 50 and 100 mg/kg improved the performance and egg quality of laying hens. However, better results were found in OM-100.

Application of different medicinal mushrooms intended to enhance production performance and health status has created an importance demand in poultry production. One goal of using medicinal mushrooms is to get rid of antibiotics in poultry feed without affecting the optimum performance. Increasing concerns about this issue have led to more attention on antibiotic substitutes and a significant demand for them for organic egg production. Thus, supplementation with medicinal mushrooms is a new concept for research in layer production, however, there is still a great deal of confusion about inclusion levels and the mode of action of medicinal mushrooms on production performance and health status in laying hens. Taking this into account, this review outlines the experimental uses of medicinal fungi on the growth performance, laying performance, egg quality, and health status of layer birds based on previous findings to date. Finally, we highlight that supplementation with medicinal fungi can play a role on the immunity, health, and production performance in laying hens.

In this study, 160 73-week-old laying hens (HyLine W-36) were used to investigate the changes in production performance and egg quality parameters of aged laying hens after injection of different doses of growth hormone (GH) and a fixed dose of testosterone (Ts). The hens were weighed individually, placed in laying cages and then randomly assigned to four treatments with four replicates of 10 birds each, in a completely randomised design. The experiment was started at the 75th week and lasted until the 82nd week of age. The treatments were: 1: injection of 100 µL distilled water (control group), 2: injection of 500 µg Ts/kg liveweight + 50 µg GH/kg liveweight, 3: injection of 500 µg Ts/kg liveweight + 100 µg GH/kg liveweight and 4: injection of 500 µg Ts/kg liveweight + 150 µg GH/kg liveweight. In this study, ovulation rate (egg production percent), egg mass and feed intake were significantly higher in Treatment 3 than the control group (P < 0.05), and in Treatment 4, feed conversion ratio was significantly higher than for the other experimental groups (P < 0.05). In addition, the birds in Treatment 3 showed greater egg weight, albumen height, eggshell weight, eggshell density and eggshell weight per surface area than the control group (P < 0.05). In Treatment 3, egg length significantly increased compared with Treatments 1 and 4 (P < 0.05), and in Treatments 2 and 4, shell breaking strength was significantly lower than for the control group (P < 0.05). In conclusion, our results showed positive effects of GH and Ts administration on egg quality parameters and production performance in aged laying hens. Taken together, in the present study Treatment 3 was found more effective in improving egg quality and production performance of the old laying hens.
