Starch

The development of rumen papilla in the dry period is essential to maximise the rumen surface area. Volatile Fatty Acids (VFA)are created by microbial digestion of fibre. The papilla are required to transfer the Volatile Fatty Acids into the cow's blood stream where they will be used as a major energy source and for milk production.

Papilla are also the major site for bicarbonate transfer into the rumen, playing a major role in rumen pH control.

The major driver for papillary development is dietary starch.

Starch in the dry cow transition period will drive papillary development, ensuring energy transfer into milk and control of acidosis.
