Late lac­ta­tion milk fever

Farm World News - - Farm World 2016 -

Late lac­ta­tion milk fever can of­ten be due to cows milk­ing harder to­wards the end of lac­ta­tion and the pos­si­bil­ity of not hav­ing enough cal­cium left in her re­serves.

Cows need cal­cium for bone and teeth for­ma­tion, trans­mis­sion of nerve im­pulses, mus­cle ex­citabil­ity, car­diac reg­u­la­tion, blood clot­ting and the ac­ti­va­tion and sta­bil­i­sa­tion of en­zymes.

Ba­si­cally, it is a very im­por­tant min­eral to the cow and makes up nearly two per­cent of her body weight.

Most farm­ers would have seen milk fever most com­monly in the herd im­me­di­ately af­ter calv­ing.

Milk fever oc­curs due to the in­abil­ity to di­gest and utilise di­etary cal­cium, or mo­bilise bone cal­cium quickly enough to sat­isfy de­mands for milk pro­duc­tion. The fre­quency of late lac­ta­tion milk fever in­creases with: cold, wet weather con­di­tions higher pro­duc­ing cows as the age of the cow in­creases so does the risk higher body con­di­tion score cows jer­seys seem to be more sus­cep­ti­ble. It is most im­por­tant for the late lac­ta­tion milk fever cows to be fed a lead feed ra­tion like CopRice lead feed prior to their next calv­ing.

The an­ionic salts help the cow ab­sorb cal­cium from her diet and at the same time mo­bilise more cal­cium from her bones.

Cows with late lac­ta­tion milk fever will be at a greater risk of de­vel­op­ing milk fever around calv­ing.
