“…The paler yolk at inclusions of 100 mg and 150 mg PGRE/kg suggests that xanthophylls interacted with ginsenosides of PGRE. Pale yolks can results from any factor that inhibits liver function, subsequent lipid metabolism and deposition of pigment in the yolk (Chukwuka et al, 2011).…”

This study was conducted to determine the effect of Korean ginseng (Panax ginseng C.A. Meyer) root extract (PGRE) on egg production and egg quality characteristics of hens at the beginning of their laying period (20 weeks old). Four groups of commercial hens (Atak-S; Turkish native hybrid) were fed with diets containing 0 mg, 50 mg, 100 mg and 150 mg PGRE/kg. Experimental results indicated that dietary PGRE had no effect on feed intake, feed efficiency, egg mass (EM) or egg production parameters. Over 12 weeks, hen-day egg production (HDP) of the groups was 73.5%, 74.8%, 69.2% and 79.0%, respectively. The effect of different levels of PGRE on egg weight, shape index (SI), specific gravity, shell thickness, Haugh Unit (HU), yolk index (YI) and albumen index (AI) was not statistically significant during the entire experiment. Egg yolk colour was conspicuously lower in the 100 mg and 150 mg PGRE/kg groups than in the control. The L*, a* and b*, hue (H) and chroma (C*) values for eggshell colour were not significantly different among the groups, except for the colour difference (∆E*, (L 2 +a 2 +b 2 ) ½ ), where values in PGRE groups were higher than in the control group. The trolox equivalent antioxidant capacity (TEAC), ferric reducing antioxidant power (FRAP) and total phenolics concentration of PGRE were 598 ± 1.841 mmol trolox/kg, 15.45 ± 0.457 mmol TEAC/kg and 1.02 ± 0.03 g gallic acid equivalents (GAE)/kg, respectively. Serum glucose, cholesterol and triglyceride concentration were similar in the PGRE supplemented groups and the control. In conclusion, the dietary supplementation with PGRE did not affect the productivity performance traits and egg quality of hens at the beginning of the laying period.

“…Shell strength can be affected by a wide range of factors including egg size, age of bird, stress to a flock of laying hens, elevated environmental temperature, nutrition and water quality, etc. (Chukwuka, et al, 2011). The harsh tropical climate and severe disease outbreaks, poor biosecurity, sub-minimal vaccination and treatment protocols, poor management practices, poor chick quality, feed-associated causes, and unintended accidents often aggravate mortality and negatively affect egg production (Shittu, 2014).…”

“…In Ukraine are produced near 100000 tones of substandard egg mass annually [5,6], that is often missed because of significant cost of its processing [7,8]. There is a possibility to use substandard chicken eggs without shell as a source of animal protein in composition of mixed fodders for poultry, namely for production of extruded feed additive (EFA).…”

On the base of practical studies were established the rational parameters of technological processes of production of extruded feed additive. There was determined an expedience of mixture of substandard chicken egg mass and the crushed corn seed in two stages in frame (during 18 s) and blade (during 120…180 s) mixers. There were determined the optimal regimes of mixture extruding: pressure in working zone of extruder 2…3 mPa, consumed force of electric motor 4,0…4,5 kW, temperature on outcome of extruder 110…120 ºС, duration of process 60…120 s, diameter of matrix port 10 mm. There were given the results of study of parameters of quality and nutritive value of extruded feed additive. It was established, that in the process of extruding the quality parameters of food additive are improved at the expense of dextrinization and gelatinization of starch, decrease of bacterial and fungal pollution, disinfection of product. There was proved a possibility to solve problem of utilization of defective eggs at feeding poultry.
