ABSTRACTADDITION TURMERIC GINGER, RHIZOME AND WHITE RHIZOME OF COMMERCIAL RATION TO EGGS’ QUALITY OF QUAILS.This study aims to determine the quality of quail eggs after added 2% turmeric (Curcuma domestica Val.), ginger (Curcuma xanthorrhiza Roxb.), and ginger and white (Curcuma zedoaria Rosc.) in the commercial ration. Animals used are of the type Coturnix-coturnix japonica quail females aged 6 weeks a total of 120 birds. Research using completely randomized design (CRD) with 4 treatments and 5 replications, and each replication consisted of 6 tail quail. Treatment is given as follows: R0 = control diet; R1= ration with 2% turmeric (Curcuma domestica Val.), R2 = 2% ration with ginger (Curcuma xanthorrhiza Roxb.), R3 = 2% ration with ginger and white (Curcuma zedoaria Rosc.). results of the study showed that the addition of 2% turmeric (Curcuma domestica Val.), ginger (Curcuma xanthorrhiza Roxb.), ginger and white (Curcuma zedoaria Rosc.) and not significantly different effect on egg weight, yolk color and egg shell thickness. And based on the results of this study concluded that the addition of 2% turmeric, ginger, ginger and white and can not increase egg weight, yolkcolor and egg shell thickness when added to a commercial ration.Keyword : Ration, Turmeric, Ginger, Ginger and White, Quail Eggs.

The relationships between 22-42 week production measurements (egg number, egg weight, feed conversion efficiency, carcass fat, shell thickness and body weight) and a number of physiological measures (metabolic rate, water turnover, thyroxine secretion rate and plasma thyroxine concentration) were examined in purebred and strain-cross White Leghorn hens. Feed intakes were restricted to 80, 90 or 100 g 24h-1 and comparisons made with birds allowed free access to feed (average 127 g 24h-1). Restricted feeding significantly depressed all production measures except egg weight and shell thickness, and also reduced metabolic rate but elevated the plasma thyroxine concentration. Strain-cross hens laid more and heavier eggs, and showed a better feed conversion efficiency than purebreds in association with reduced metabolic rates, thyroxine secretion rates and plasma thyroxine concentrations. Water turnover was the only physiological measure to be consistently related to production measurements, and in the case of egg number, egg weight and shell thickness, different relationships were demonstrated in restricted compared with fully fed birds.

Phosphorus Levels

The effects of diet type (wheat- or maize-based) and concentration of available phosphorus (AP; about 4, 3 and 2 g/kg) on the parameters of hen performance and egg quality as well as shell calcium (Ca) and phosphorus (P) contents were examined. Two experiments were carried out in which 240 and 120, respectively, older ISA Brown hens were housed in enriched cages. The interaction of diet type and AP concentration was ascertained for all evaluated characteristics except the amount of Ca and P deposited in shells in the first experiment. In the second experiment, the interaction of diet type and AP concentration was found for feed intake, egg weight, shell thickness and weight as well as the albumen quality parameters. Furthermore, Ca deposition in shells increased (P < 0.001) with the wheat diet. Hens fed a maize-based diet (P < 0.001) laid heavier eggs. The highest level of AP (4.1 g/kg) in the wheat-based diet significantly (P < 0.001) decreased albumen height, albumen index and Haugh units (HU). These trends were the same in both experiments. The results indicate that 0.27% AP in wheat-based diet and 0.30% AP in maize-based diet are adequate for hens with the intake 115 g of feed with 3.5% of Ca without a negative impact on performance or egg quality.

The paper discusses the relations between some physical indicators of market eggs of laying hens housed in conventional and enriched cage batteries. The measured results were evaluated by the multiple regression dependence method. They show that in the case of both the conventional as well as the enriched cages a statistically significant dependence exists between the eggshell deflection (dependent variable) and thickness, or the force needed for the eggshell destruction (independent variable). The respective P values are given in brackets (0.002 &lt; 0.05; 0.03 &lt; 0.05; 1.16 &times; 10<sup>&ndash;10 </sup>&lt; 0.05; 8.31 &times; 10<sup>&ndash;4 </sup>&lt; 0.05); in the case of the conventional cage and enriched cage also a statistically significant dependence existed (3.81 &times; 10<sup>&ndash;91 </sup>&lt; 0.05; 3.86 &times; 10<sup>&ndash;81</sup>; 1.27 &times; 10<sup>&ndash;97 </sup>&lt; 0.05; 3.46 &times; 10<sup>&ndash;57 </sup>&lt; 0.05) between the shell weight (dependent variable) and shell thickness, or egg weight (independent variable); in the conventional cage, statistical dependence also occurred between the eggshell weight and egg shape index, (1.07 &times; 10<sup>&ndash;6 </sup>&lt; 0.05), in the enriched cage this was on the verge of statistical significance (0.062 &gt; 0.05); if in the conventional cage the eggshell thickness was increased by 1 mm, the shell deflection decreased by 0.08 mm,and if the force necessary for the eggshell destruction was increased by 1 N, the shell deflection decreased by 0.0003 mm; if in the conventional cage the shell thickness was increased by 1 mm, the shell weight increasee by 15.509 g and if the egg weight was increased by 1 g, the shell weight increased by 0.061 g. Our work brings further knowledge concerning the monitored characteristics and their mutual relations.

The comparison of physical quality properties of table eggs of commercial hybrid Tetra SL and two native indigenous breeds of hens, Banat Naked Neck and Svrljig hen, was performed in conditions of alternative production in the pasture system in portable cages without the floor. The experiment was conducted during the vegetation period, at the age of hens of 53-57 weeks. In order to produce good quality eggs, the diet was designed with a complete mixture based on maize and soybean. In addition, constant availability of pastures was ensured. Egg sampling was performed in the morning and the initial egg quality was examined based on egg weight, shape index, egg white, egg yolk and shell quality parameters. Layer hens of the commercial hybrid Tetra SL had significantly higher egg weight and better internal egg quality (p<0.01) compared to hens of Banat Naked Neck and Svrljig hens, except for the colour of the yolk, which was more intense in the same feeding and breeding conditions and the age of laying hens, in eggs of native breeds (p<0.01). Native breeds in relation to the commercial hybrid had lighter shell colour (p<0.01). Deformation and egg shell thickness differed (p<0.01) between all three genotypes. The determined rank of layer hen genotypes for shell thickness was: Tetra SL, Banat Naked Neck, Svrljig hen. However, the breaking force was without statistically confirmed difference between hen genotypes.

Two 280-day trials, each involving 468, 22-week-old caged commercial egg-strain pullets were conducted to Compare millet and sorghum grain as the main source of energy in laying diets. Diets containing 59.2 and 0, 41.0 and 24.0, 31.2 and 36.3 and 0 and 72.5% of sorghum grain and pearl millet, respectively, were studied in both trials The diets containing millet supported egg production, egg weight, feed conversion and egg shell thickness equivalent to those of the all-sorghum diet. Except in Trial 1, feed consumption of the pullets fed the millet-containing   diets was not significantly lower than that of the pullets fed the all-sorghum diet. Haugh unit values tended to decrease as the level of millet was decreased. Feeding millet at a level as high as 72.5% Of the diet may have adverse effects on egg specific gravity and haugh units
