Timaru 29 April: Pasture covers have started to increase on Hayden’s South Canterbury dairy farm, with the most recent average reaching 2280 kg DM/ha, and that’s a welcome change after a long and challenging dry spell.
Daily production from 750 cows on OAD milking is 1.2 kg MS/cow, with a diet of 10-11 kg DM/day pasture, 3 kg cereal silage and about 2 kg PK. The grazing round has tightened up to 48 days as growth rates have improved.
Hayden’s aiming to milk through to late May with dry-off targets of 1950 kg DM/ha covers and 4.5 cow BCS.
At this stage winter feed crops continue to look pretty good, with dryland fodder beet having grown surprisingly well.
Hayden has upgraded his irrigation system this season which will allow better use of available water which is expected to significantly improve pasture growth during summer months
Lack of water during this past season has seen farm working expenses go from a budget of $3.50/kg MS before interest to $4.50-$4.60.
Overall total costs are actually down, because Hayden has spent less on nitrogen and power for irrigation, but this has been outweighed by the drop in MS production after irrigation was cut by half in December then turned off completely in late February.
