[Assessment of marbling in the eggs of local beeds of chickens].
A test was worked out to evaluate the presence of marbling in hen eggs, modifying Koulikov's method. Its use with a total of 26,011 eggs of hens, belonging to local breeds, revealed the presence of weakest, weak, and moderate marbleness as most frequently occurring (32.72; 48.53; 15.57 per cent); strong, and very strong marbling occurred least frequently, and third ranked the lack of marbling 1.92; 0.76; 0.48 per cent, respectively. The incubation of eggs of the same breeds showed that strong and very strong marbling affected adversely the results of hatching. The test can be applied in the productional and diagnostic control on hatcheries.
