Macalister Demonstration Farm

Macalister Demonstration Farm Update 451 (Week ending June 16, 2017)

What’s been going on at the MDF?

The MDF is winding down for the 2016/17 season, with 110 cows being dried off on the 16th June, and another 30 to be dried off on Monday 19th June. These 140 cows will leave the farm and go to agistment on the 21st of June. This will leave 110 cows remaining in the milking herd which will be dried off in mid July. Net margin after supplements is significantly higher than last fortnight, due to a lot of the lower producers being dried off resulting in an increase in average cow production per day of 0.44kgMS, combined with the removal of silage from the diet, hence a reduction in the cost of ‘supplementary feeding’.

As this report has been done in the middle of drying off a significant number of cows, some of the calculations are somewhat ‘moving targets’. The diet of the milkers has changed over the past week with the last of the silage being fed out. They are now on pasture and grain only.

In preparation for the upcoming season, the 68 in-calf heifers will be returning to the farm from agistment on the 25th of June. Following their return, they will be introduced to the dairy where they will be fed 1kg of grain per day to make their entrance into the milking herd and the dairy environment less stressful following calving, and to prepare them for the a diet of pasture and grain. The heifers are due to start calving from August 1st, and will also be fed hay between now and calving.
