Preliminary Study: Egg Production Performance, Egg Quality and Blood Plasma Cholesterol Concentration in Laying Hens Fed Dietary Dried Fermented Ginger and/or Fermented Corncob Powder

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.

One hundred and twenty (100♀ + 20♂) 30-weeks-old dual-purpose breeding hens of Gimmizah strain were housed in individual cages in a semi-open house. Birds were distributed randomly into five treatments of 20♀ + 4♂. The 1st treatment was fed a control (unsupplemented) diet (17.5% CP and 11.4 MJ per kg diet) containing 0.10 mg Se/kg (low level). The 2nd, 3rd, 4th and 5th treatments were fed the control diet supplemented with 0.15 and 0.30 mg Se/kg from inorganic (sodium selenite) and organic (selenomethionine, as Se-yeast Selplex® Alltech, Nicholasville, USA) sources, respectively. The total concentration of Se in experimental diets was 0.25 (medium level) and 0.40 ppm (high level). Feed and water were provided ad libitum throughout the experimental period (30–50 weeks of age). Different Se levels of the organic and inorganic form and their interaction did not significantly (P > 0.05) affect egg production percentage, and most of egg quality traits. Egg weight and egg mass significantly (P < 0.002) increased and the feed conversion ratio (FCR) significantly (P < 0.04) improved due to Se supplementation compared with hens fed the control diet. Piped embryos and spleen percentage significantly (P < 0.05) decreased due to Se supplementation. In addition, the level of organic and inorganic Se and their interaction significantly (P < 0.0001) decreased the plasma cholesterol concentration. Tibia Ca and P percentages and yolk selenium concentration significantly (P < 0.03; P < 0.0001 and P < 0.0001, respectively) increased due to Se supplementation and the greatest increase was recorded by a group fed diet with the high level (0.40) of organic Se. The duodenal and intestinal mucosa of the ileum was negatively affected by the high level of inorganic Se while chickens fed the organic form showed less toxic effects in hepatic and splenic tissues than those receiving the inorganic form. In conclusion, the organic and inorganic Se supplementation at 0.15 and 0.30 mg/kg diet, which corresponded to a dietary level of 0.25 and 0.40 mg/kg diet, improved the productive and reproductive performance of Gimmizah breeding hens. A decrease in plasma total cholesterol and an improvement in the bone mineralization were observed. The level of 0.25 mg/kg diet of organic Se was adequate to enrich eggs, which may be recommended for practical application and which would improve the consumer health benefit.

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.

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.
