Farm manager Peter Hancox said the farm was tracking well this season and was on target to produce around 500 kg/ms per cow for the season, with 556 cows milking at peak, and the irrigator had been turned on for only 35 days so far, compared with 60 days at the same time last year.
He said the farm's management had opted to go through mating without using bulls, with mixed success.
''It was quite a challenge with the yearling heifers, which were in Ashburton, so going down each day wasn't an option.
''There was a lot of rain before Christmas so it was quite a challenge and the days we went down it was raining, so it didn't go well.''
After four rounds of intensive artificial insemination there was a ''28 per cent empty rate'' among the heifers.
He said they began artificially inseminating the main herd a week earlier than usual, producing a six-week in-calf rate of 71 per cent, a significant improvement on the 63 per cent it achieved three years ago.
After 10 weeks there was still a 16 per cent empty rate, which was ''not too bad considering the results we have been hearing from other farmers, but we would have liked to get it better than that''.
