to combat clinical and subclinical milk fever

Normal cow blood calcium levels are essential for optimal fresh cow health, milk production, reproduction and overall productive life.

A deficit of blood calcium at calving causes milk fever. Extremely low levels of blood calcium result in clinical milk fever which requires treatment and can be financially significant.

However, even low levels of blood calcium can cause subclinical milk fever which is even more

costly because it affects a much higher percentage of fresh cows.


X-Zelit offers a unique approach that is both effective and easy to use:

1. Feed X-Zelit at 500g/head/day for 14 days before calving via purchased lead feed, own mix or top dress (remove negative DCAD products or calcium supplements).

2. X-Zelit reduces dietary calcium and naturally activates the Parathyroid Hormone (PTH) system to mobilise skeletal calcium reserves and maintain healthy blood calcium levels after calving.

3. Feed a balanced diet including your home grown pasture, hay and silage plus the standard dose of 50g/head/day of magnesium oxide.

4. Expect better calving, milking, overall cow health and welfare.

DO NOT feed to lactating animals.

DO NOT feed in conjunction with negative DCAD or high calcium additives.

For every cow with clinical milk 

fever (cost $400) there can be

up  to 8 cows with subclinical

milk fever (cost $1000).
