Main herd: 401 M.A. cows, milked twice a day
Small herd: 51 lower BCS cows + 17 lames, milked once a day
75 culls have left the farm and another 40 are going this Friday.
We will be doing our final herd pregnancy test on 17 May to check for any late slips. This will prevent us from wintering cows that won't be in milk next season.
Dry-off date will be 27 May. Any cows that have exceeded the SCC threshold on herd test results plus any treatment cows during lactation will receive Dry Cow antibiotics plus teat seal. Cows that haven't exceeded the SCC threshold will receive teat seal only. This will be done with help from our vets to ensure a very high standard of hygiene. Cows will be trucked to winter grazing on the same day. Cows will be monitored very closely for the first few days for any signs of mastitis.
Latest BCS figures: average 4.4, as at 29 March 2021. Final assessment will be done on 10 May to set up groups for wintering according to condition. We will have 3 mobs: Lights that need to gain 1 Body Condition Score, Mids that need to gain half a BCS, and Fats that will be fed maintenance rates over winter.
3.6mm rainfall this week. No irrigation on farm this week.
Average soil temperature dropped significantly this fortnight from 12.8°C to 9.6°C. We have had a full week of very heavy frosts.
Growth rates have dropped from the unusually high 56 kgDM/ha/day 2 weeks ago, to 37 kgDM/ha/day.
Average pasture cover: 2,317 KgDM/ha, which is still about 100kg above target. Aiming for closing cover of 1900 on 1 June, so will need to see this come down over the next weeks. Can achieve this by feeding less balage. Average balage this week has been 6.6 KgDM/cow/dayz, so this can be pulled back as needed.
Pre-grazing cover demand for pasture-only diet (calculated based on cow numbers after all culls have gone next week, i.e. 425 cows): 3,162 KgDM/ha/day entry cover needed, for 17 KgDM/cow/day on minimum 33 day round (4.84 ha/day).
We have now finished applying N fertiliser for the season.
Below is our autumn spring tracker that we will monitor over the next 6 months. The plan is to finish the season with an Average Pasture Cover of 1900Kg DM/ha. This is anticipating similar winter growth as in recent years (and acknowledges the amount of the farm in more winter active - hybrid perennial ryegrasses). The target APC at the end of July remains at 2600kgDM/ha and requires an average growth rate over the winter of 11.5kgDM/ha/day during June and July.
