Supplementing
Summer Pastures Doesn't Cost...IT PAYS!
|
Did you know that the nutrient demand of a summer
lactating cow is 50% MORE than a dry pregnant cow in winter? |
Did you know that summer pastures DO NOT supply minimum levels of
phosphorus, trace minerals and vitamins? |
| Supplementing livestock rations with a Kay Dee Mineral year
’round will ensure maximum productivity. |
 |
| It’s common practice to supplement winter rations, but the nutrient
demand of a lactating cow is highest in the summer. (see Table 1) |
Most pasture grasses do not supply recommended daily amounts of
phosphorus, trace minerals and vitamins.
(see Table 2) |
- Early spring grasses are washy
- Dry conditions reduce nutritional value
- Years of grazing on unfertilized ground creates soils low in phosphorus
- Late season grasses are low in nutrition and less palatable
