##article.abstract##

The efficiency of industrial poultry farming within the optimization of poultry
technology, depends on the level of genetic potential of the flock. Selection
features of Shaoxing ducks make this kind optimal for its breeding in the People's
Republic of China. The study aims to evaluate the morphometric characteristics of
Shaoxing duck eggs, which are bred on the breeding farm of Zhejiang Generation
Biological Science and Technology Co., Ltd in Zhuji, Zhejiang Province, China.
The weight, length, width of the eggs and the index of the egg shape have been
determined. An individual method of counting the number of eggs laid by ducks of
the Shaoxing breed for 4 adjacent months has been implemented. The average
weight of the egg is 67.45 ± 0.22 g with limit values lim max = 89 g lim min = 45
g. The average value of egg length is 6.02 ± 0.01 cm, width – 4.45 ± 0.01 cm. The
duck egg shape index is 74.01 ± 0.12. Thereby systematic individual studies of
morphometric parameters of eggs will increase the effect of selection by expanding
the indicators of lifelong assessment of the uterine population of ducks. Selection
of queens for the breeding core of the breed according to the indicators of
manufacturability of morphometric parameters of eggs will increase the incubation
yield of ducklings and, accordingly, will be one of the effective mechanisms to
ensure economic profitability of breeding Shaoxing ducks.
