The purpose of this study was to compare the performance and egg quality parameters of two layer hybrids (Lohmann Brown and Atak-S) which were reared in free-range system. The experiment was carried out with a total of 300 laying hens. From 18 to 50 weeks of age Lohmann Brown (LB) and Atak-S (AS) were housed in two groups of 150 hens in a poultry house with a stocking density of 7 hens/m2. The 2 trial groups were formed from 10 repetitions each consisting of 15 hens. At the 20, 30, 40 and 50 weeks of ages, the production performance and egg quality parameters were evaluated. Mean daily feed intake and feed efficiency through the trial were 111.2 g vs 124.3 g, and 2.46 vs 2.58 respectively for LB and AS hybrids (P

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.

Organic Minerals

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.
