Beef sire evaluation method was investigated under the field conditions with small scale farms. The 6,848 records on fattened steers of the Japanese Black Cattle were obtained from 1981 through 1987. The average head of steers in the subclass of market-year-farm was 5.2. Sires were evaluated using the best linear unbiased prediction (BLUP) method with maternal grandsires. The regression coefficient of the value realized in progeny on the expected value calculated using the BLUP nearly equaled one. It was demonstrated that the BLUP would be very effective, even using the field records collected from small scale farms.
