The purpose of this study was to determine the genetic analysis of the Brown cattle herd of Van Agricultural Vocational High School. The heritability estimates were 0.359+0.059, 0.356±0.059, 0.254+0.059, 0.224±0.058, 0.071+0.104, 0.063±0.098 and 0.142+0.038 for lactation milk yield, 305 day milk yield, average daily milk yield, lactation period calving Interval, service period and gestation period respectively. The repeatability estimates were 0.892+0.236, 0.758+0.243, 0.767+0.222, 0.821 ±0.212, 0.143±0.039,0.306±0.058 and 0.462+0.174 for the same traits. By taking the weighed means for the years under the consideration, the phenotypic and environmental change per year was estimated as -16.95 kg and -29.90 kg respectively. The genetic change was calculated to be 12.95 kg per year according to the values given for the environmental and genetic trends. On the other hand, the genetic trend in milk yield of cows in the herds from 1969 to 89 was estimated as 15.15 kg/year. About 94.35 % of this gain came from the selection of dams of sires.
