Week ending 23-9-19 farm notes:
- 113 heifer calves were weighed on 19th September; they had an average weight of 64 kg.
- Growth rate for the week was 53 kg DM/ha/day and cover dropped slightly to 2169 kg DM/ha. Achieving target residuals has been challenging this week. We have pre-graze mowed 6.5 ha that had higher than desired residuals after the last grazing. 19 ha are ear-marked for silage to be cut on 10th October, weather permitting. 7 ha are due to be sprayed out for crop on 30th We have projected out our feed wedge for the next 4 weeks and are comfortable that this will deal to the surplus, if growth rates stay at or below 70 kg DM/ha (long-term peak growth rate for the farm).
- Area allocation is 160m2/cow/day which will reduce as we push the cows through the paddocks with 2900 kg DM/ha pre-grazing on our wedge over the next week in an attempt to get into 2700-2800 kg DM/ha pre-grazing covers again.
- 83 non-cycling cows have been identified, of which 70 meet the criteria to receive a CIDR. These cows have calved more than 42 days, are less than 8 years old and not on the cull list. This is double last year’s number, but the CIDR programme has been brought forward 7 days earlier. The plan is for these cows to have their first insemination in the first week of mating (prior to using the sexed semen). These girls will be mated to premier sires.
- Cows have been producing over 2.1 kg MS/cow/day for the last 5 weeks, predominantly on all grass. The feed analysis from samples taken last week shows an average DM% of 12.3 (range 12.1 -12.8) including annuals. The average ME of the samples was 12.3 (range 12.1 -12.7). Crude protein ranged from 25-30% DM.
- We also had our effluent sampled from the pond and this will be used to inform fertiliser applications in conjunction with our fertiliser rep.
- Feeding levels past week:
- Milkers: 19.5 kg DM grass
- We look forward to seeing you all tomorrow, Wednesday 25th September to discuss in more detail.
