Feeding Hay and Silage in the Heat

Conserved forages can fill feed gaps in summer by transferring the high quality feed conserved in periods of surplus, to be used in times of deficit.

High quality silage or hay can be used to supply additional energy and protein to cows grazing lower-quality pastures. During hot and humid conditions, the intake of lactating cows falls significantly. Feeding high quality silage in a shaded area, in conjunction with a high quality pellet such as CopRice Summer Special in the dairy, will help to maintain dry matter intake and milk production. 

The Fibre (NDF) and Metabolisable Energy (ME) content of silage are important factors influencing milk production. The NDF (fibre) must be ‘effective’ in stimulating rumination and saliva production (buffering the rumen) to prevent a fall in rumen pH and potential risk of acidosis. NDF levels should be balanced as not to slow digestion too much and reduce intake further. ME levels need to be high enough to supply enough required to support good milk production.


CopRice pellets are specially formulated to compliment the available feed resources on your farm and can be used to assist the following:

• Boost the total feed intake

• Increase energy and protein content of the diet

• Rectify any specific nutrient deficiencies in forages

• Supply essential vitamins and minerals that may be lacking at this time

• Minimise potential losses in milk production


Hay and silage can be used to:

• Stimulate rumination and produce saliva

• Buffer acidity in the rumen 

• Reduce feed costs

• Fill the feed gap when pasture is limited
