wrong sex, they usually get destroyed when they cannot be of any economic value. this could prevent the purpose of animals that are destined to be quite quickly destroyed and i think that is a good thing. in the repository were focusing on chickens and eggs. just how significant this be commercially into the future? if it works, if it works in other animals and even more importantly if it is proven to be safe because before this is used we need to go through several generations of animals to make sure it does not have any ill effects on the chink is or the calves, the piglets that get on, if it works, i think it could have significant effects and the industries in making it more efficient towards derek, beef, pork and for chickens and eggs as well as perhaps sheep and goats. eggs as well as perhaps sheep and goats-
with the omicron strain but they do seem to make its effects far less serious. scientists in britain have used gene editing technology to create female only and male only litters of mice. they say their technique could eventually be applied to chickens to ensure that only egg producing females are hatched. our science correspondent pallab ghosh reports. half of these chicks are useless to the farming industry because they re male and don t lay eggs so they have to be killed. that problem could be solved thanks to a breakthrough that enables scientists to reprogramme animals to produce only females. some 6 to 7 billion male layer chicks are killed every year shortly after birth at a point when they have a nervous system and are capable of suffering. we would like to be able to move to a system where those same eggs are laid but instead never hatch. scientists at the francis crick institute in london have found
