Control measures include feeding molasses-treated chopped straw<sup>1</sup> as part of the ration during the dry period to maintain rumen size and microbial function. Dry matter intakes should be as high as possible during the dry period, and on the day of calving in particular. There must be 24 hr of easy access to the diet – one should not rely on feeding refusals from the milking herd ration to the dry cows. Any dietary changes must be introduced gradually. Most high-yielding cows are fed a total mixed ration which has the benefit of creating a more stable rumen environ - ment than that achieved with separate concentrate feeding. Cows should enter the dry period in BCS 3 (scale 1–5) and maintain that value until calving.

Cattle Medicine 1.jpg


A 5-year-old Holstein cow, which calved 1 month ago and was previously yielding 42 L/day, presents with a poor appetite and milk yield which has fallen steadily over the past 2 days to 22 L/day. The cow has been licking at objects such as walls and her own flanks for long periods of time. The rectal temperature is normal. The cow has a gaunt appearance with sunken sublumbar fossae consistent with a reduced appetite. The cow is constipated while other cows in the high-yielding group have soft faeces.
