Imagine if half the feed you bought blew off the back of the truck before it even got to your farm.
That's the equivalent of what can happen without good on-farm wastage practices during delivery and storage, mixing of diets and feed-out.
The cost of feed wastage is assessed as:
1. DM amount bought that is offered to cows but not eaten.
2. Losses in feed quality such as reduced energy and protein value, contamination with moulds.
- Feed losses are most significant during feed-out.
- Much more feed is wasted (up to 30%) when it is fed out on bare ground in the paddock or along a roadway than when fed out using a feed-out facility.
- Make realistic allowances for feed wastage when developing your feed budget.
- Even in a purpose-built feed-out facility it is difficult to totally eliminate feed wastage (because cows tend to toss feed over their backs while eating) - headlocks can minimise this.
