Week ending 16/9/19 farm notes:
- We now have all 405 cows calved with 13 days until mating starts!
- 113 replacement heifers are all now on OAD feeding, dehorned and the first mob of 41 calves weighing 60kg+ are enjoying their time outside. Calves are due for their second recorded weighing and their booster lepto and 5n1 injections on Friday.
- Pasture growth rates have for 2 weeks been above demand at 65 kg DM/ha/day this week increasing cover to 2212 kg DM/ha.
- Area allocation at approximately 158m2/cow/day on a 23 day rotation is ensuring the cows are being well feed allocating 19.5kgDM/c/day (which is approx. 4% of their liveweight). Pre-grazing covers ahead this week are around 2800-2900 kgDM/ha which indicates that target residuals will not be meet unless we start to manage surplus feed. Take a look at the feedwedge!
- Focus is shifting to cropping, pasture improvement and silage making. We have followed the cows this last week through 30ha which received plantain broadcast via the Mag spreader at 4kg seed/ha mixed with sand as a carrier. This is targeted for paddocks that have recently come out of crop or else are not due for cropping within 2 years.
- Spraying out the first 5 ha (from 12ha) for crop will occur at the end of the month due to be drilled on the 10th October for Turnips. We are trying to co-ordinate our silage to align with this to make it cost effective adding to our existing stack (of 100tDM remaining).
- Pre-mating heat detection and recording has started and 29% of cows were observed cycling in the first 7 days and another 21% in the second week. This information highlights any non-cycling cows that we can make decisions on in the next few weeks.
- Mating will commence on the 30th of September. We have 100 sexed semen straws to use from the 5th October on the top 80% of BW cows. All other cows mated prior to and during this period will be mated with Premier sires. From the start of mating the bottom 25% of BW cows will be mated to Wagyu along with all cows that cycle from week 5 to week 7. After this the remaining cows will be mated with short gestation diary semen.
- The Dosatron is delivering 100g MgCl/cow/day to all cows. The milking herds are getting 50-60g MgO/cow/day and 100g Limeflour/cow/day dusted onto the paddocks. This works out to be approximately 23g Mg/cow/day based on our estimated wastage and drinking volumes.
- Feeding levels past week:
- Dry cows: 8 kg DM grass
- Milkers: 19.5 kg DM grass
- We look forward to seeing you all next Wednesday 25th September to discuss in more detail.
