Egg-laying capacity of parent flock geese at different stocking densities.

This article presents the results of studies aimed at establishing the optimal stocking density of purebred and hybrid geese of the parent flock, taking into account the indicators of their live weight and egg production. When conducting research, the stocking density of geese was established depending on the breed and shape. Different stocking densities of geese in groups were achieved due to their different numbers in groups: Kuban 1.

Productive qualities of geese when crossing breeds and using hepatoprotective complex.

The study was on a one-way cross between Wanxi male and Lindov female geese, and tested the effects of a hepatoprotective compound on growth and other traits in the parental and one-way cross involving male and female progeny. The hybrids obtained from crossing had high viability and productivity; their level was also positively affected by giving a hepatoprotective complex. Female parents were the Lindov breed's geese, and male parents were 120 geese of the Chinese Wanxi breed.

Effect of hydroponic green herbage on the productive qualities of parent flock geese.
