In-shed feeding systems
A recent market research survey showed that 28% of New Zealand dairy farmers in Canterbury and the North Island have an in-shed feeding system. The key benefits and limitations of in-shed feeding systems are shown in Table 9.
|Table 9: Benefits and limitations of in-shed feeding systems|
|High utilisation with energy dense feeds.||Milk returns can be variable depending on the payout and
the milksolids response.
|More accurate dispersion of minerals to every cow.||At times it can be hard to source some concentrate feeds.
(e.g. during a drought).
|With new meal feeding technology individual cows can be allocated feed depending on their milk production level.||Feeding concentrates in the shed can, depending on the
feed cause unsettled milking (flies, cows not wanting to
leave shed etc.).
|Minimal labour. It is relatively easy to adjust feeding rates and cows can normally be fed by simply pushing a button or pulling a cord.||Cows cannot be stood off pastures and it is impossible to feed large quantities of feed or forages through a meal feeding system. Feeding dry cows can be a hassle.|
Every cow has the opportunity to eat an equal amount of feed
|Intake is limited to a maximum of 4-5kg/DM.|
|Repairs and maintenance costs are typically very low.||Due to the price per unit of energy farmers need to achieve greater milk response rate per kgDM fed for concentrates when compared to forages.|
Cost of in-shed feeding systems
The approximate capital cost of a meal feeding system including a hammer mill for a 60-bale shed is $70,000. Costs are as follows:
|Table 10. Approximate cost of feeding supplements through a meal feeding system.|
|Interest ($80,000 @ 6%)||$4,800|
|Depreciation (assume 20 year life)||$4000|
|Repairs and maintenance||$700|
|Cost per kgDM (assuming 200tDM/year )||
