Journal Title: Наукові доповіді НУБіП України - Year 2017, Vol 6, Issue 6
Abstract
The purpose of this study was to monitor the egg productivity of the Shaoxing breed ducks from the age of 24 (beginning of egg laying) and 75 (end of egg laying) weeks. According to the results of a study of over 2385 eggs, a significant difference was found between the weight indicators (57.93 g and 70.81 g; p˂0.01), the shape index (73.71% and 75.35%, p˂0.01), the strength of the shell (4.92kg and 4.28kg; p˂0.01), the thickness of the shell of the egg (0.48mm and 0.45mm; p˂0.01) in ducks at the age of 24 and 75 weeks. It also shows changes in the weight and shape of the egg with the age of the bird. The necessity of further studying the genetic diversity of birds, which causes the separate variability of indices of individual ducks, is substantiated.
