An Update on the Performance of the Spring & Winter Milking Herds

Johnstown Castle farm manager Aidan Lawless joins Emma-Louise Coffey to discuss full lactation performance for the winter milk herd and current milk and grass production.

The winter milk herd have produced 620 kg MS approximately 20 kg ahead of 2017 and 2018 lactations. Aidan credits increased milk yield, rising milk solids and getting out to grass in early January as factors that have driven high milk output. 

40% of the winter herd are still milking and will be dried off this week, currently on a restricted diet with the view to depress milk yield. Aidan is extremely happy with fertility performance recording just 8% empty this year.  The spring herd are currently milking 23 litres or 1.8 kg MS, declining from peak of 32 litres.
 

Grass production was a challenge in July with a substantial soil moisture deficit and growth rates half of projected growth based on the Johnstown Castle average. Heavy rainfall in late July/early August has helped recovery to normal growth.
 

Finally, Aidan highlights the upcoming Winter Milk event at Johnstown Castle on the 4th September, covering a range of topics from feed management, genetics, fertility to soil fertility.
