Target milk production for the 15/16 season is 340,000kgMS, 470kgMS/cow or 1300kgMS/ha.
There was an average of 546 cows being milked twice a day into the vat for collection this week. They produced (as an average over the week, sold to the factory) 1.45 kgMS/cow/day.
There was an average of 60 cows being milked once a day into the vat for collection this week.
5 cows are being treated for mastitis and their milk is being discarded.
Month to date production for April is 3461 kgMS, this was down on the 14/15 season and down on our target of 4267 kgMS.
Month to date production for March was 30336 kgMS, this was down on the 14/15 season and down on our target of 35000 kgMS.
Daily production for the 15/16 season is 830 kgMS/day (606 cows in vat) compared to the 14/15 season at 1022 kgMS/day (694 cows in vat) and 1179 kgMS/day (731 cows in vat) in the 13/14 season.
Season to date production is 272903 kgMS, this is 6.6 % below the 15/16 season to date target of 292267 kgMS.
The Management team have been observing the upward trend in MU levels to above 40 since the onset of April. Observation would tell us the amount of clover and high quality pasture on farm down to grazing residual level (1550-1650KgDM/ha) is surperb quality - however our observation will be validated this week with several herbage samples taken in pre-grazing paddocks of cover 33-3500KgDM/ha too be analysed and reported back on in the next few weeks. This will provide us wiith key information around crude protein levels, DM%, fibre content and also what energy content is in the diet being offered. At this stage of late lactation we would be looking for a no less than 14% CP in the diet, minimum DM% of 15-17% and fibre contents above 35% NDF.
Trying to compare seasons with seasons is really irrevelevant as climatic conditions dictate crude protein levels in pastures, feed quality and clover content. Clover contributes to increased voluntary intake and also diet quality, in terms of ME and lower NDF content which allows for an increase in energy intake in the diet. Another factor in the variation or 'swings' in MU levels can be the difference in grazing new young pastures vs older well established pastures and the difference in their nutriotional profile. So for the management team at SDF they provide some insight into what could be happening nutritionally, but we certainly don't make our feed decesions based on it, rather preferring herbage analysis to give us a detailed nutritional profile of the pasture being fed to the cows.
