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

Abstract

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. During the growing period, hybrid young birds were receiving a hepatoprotective complex in the amount of 1.0 mL per 1 L of water for 7 days. The research took into account geese' safety indices, live weight, and absolute and average daily gain. The interbreeding results prove that the resulting hybrids' safety index is 2.38%-4.54% higher than the parent forms' safety index. The hybrids' live weight increased by 8.4% due to a higher increase in live weight by 16.5%-22.1% allowing us to conclude the positive effect of crossing and using a hepatoprotective complex when breeding geese. The research made it possible to improve geese' productive qualities through hybridization and the use of a hepatoprotective complex. This information can contribute to the genetic improvement of body size in current breeding programs.
