Effect of genetic changes in egg production, growth rate, semen yield and response to cold stress on early mortality of turkey poultsABSTRACT Mortality during the early growing period of turkeys was increased by genetic increases in egg production in a medium weight line (E) but genetic increases in both 16-week body weight and egg production in a large weight line did not influence poult mortality....
