Systematic environmental influences and variances due to direct and maternal effects and trends for yearling weight in cattle
Pedigree yearling records from 1021 local Tuli calves born at Matopos Research Station were analyzed for non genetic factors, genetic parameers and trends on the yearling weight. It was found that sre year of brth, sex of calf age of dam had sgnfcant effect (p Keywords: Non genetic, Direct, Maternal trends, Yearling weight, Growth traits, Tuli cattle
