Breeding for Reduced Methane Emissions in Livestock Species

Livestock improvement has taken quite a rapid pace in past two or more decades. The era of rapid genetic progress started with the advent of biotechnological tools specially like artificial insemination, multiple ovulation embryo transfer, in vitro maturation and fertilization, coupled with breeding programs like progeny testing and open nucleus breeding schemes, these played an important role in increasing the selection intensity not only in males but in females and also in improvement in number of observation per individual.
