An experiment was conducted to investigate the effects of using different levels of Red Pepper powder (RP) and Marigold flower powder (MF) on egg production, egg yolk color andsome blood metabolites in laying hens. Ninety, 103-weeks old laying hens were divided into 5 treatments groups of 6 birds in each cage with 3 replicates in a completely randomized design. The birds were fed a corn-soybean...

Serum (n = 1,636) and egg yolk (n = 802) samples collected from hens on four commercial egg farms in Florida were tested for the presence of specific antibodies to Mycoplasma gallisepticum in a commercially available enzyme-linked immunosorbent assay. No significant differences were noted between serum and egg yolk samples with respect to distribution of positive, suspect, and negative test res...

this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...

Yolk steroids of maternal origin have been proposed to influence genetic sex determination in birds, based on sex differences in yolk steroid concentrations of peafowl eggs incubated for 10 days. More recent reports dispute this proposal, as yolk steroids in eggs incubated for 3 days do not show such sex differences. To date, research examining this phenomenon has only analysed incubated eggs, ...

When one heats the yolk, changes occur in the fragile elements that serve to support the vital life force within the egg. The egg yolk, in many ways, is not very different from your own cells. Once your temperature goes above 105 degrees you will start to suffer serious health problems. Similarly, heating the yolk above 105 degrees will also start to cause structural changes in many of the high...

in the egg shells when the eggs were studied in UV-light (Fig. 1). Control eggs did not fluoresce. The concentration of oxytetracycline in the egg shell, albumen, and yolk was measured by UV-absorption spectrofluorometry (Hayes and DuBuy, 1964). Oxytetracycline was deposited mainly in the shell (0.182 ± 0.028 iig./gm., mean ± SD), and albumen (0.190 ± 0.030 !*g./gm.) whereas the yolk contained ...

In this experiment, a total of 128 Hy-line W36 hens at 63 weeks of age were used. The hens were put at random into 4 treatment groups (4 replicates and 32 hens per treatment) and were fed four different diets: three diets with different levels of Spirulina (1.5, 2.0 and 2.5%) and one control group based on wheat and soybean meal. All birds were housed in commercial cages, had ad libitum access ...

When Bacillus anthracis is grown in egg yolk medium, a reaction occurs which is presumably due to lecithinase (Colmer, 1948; McGaughey and Chu, 1948; Chu, 1949). In liquid egg yolk medium the lecithinase reaction is characterized by the formation of an opalescent suspension and flocculation of particles which rise to the top of the medium as a curd. A test such as this is usually referred to as...

This study was conducted to investigate the cholesterol-lowering property of garlic (Allium Sativum) in whole blood of egg yolk induced hypercholesterolemia in rabbits. Forty rabbits of both sexes of 13.1 ± 28.4 weeks of age with average body weights of 1251.9 ± 512.2g were used for the experiment. The animals were divided into eight groups comprising control and seven experimental groups with ...
