Diagram you, the production cycle of a dairy products cow.

Following calving the cow ought to be back in leg after eighty five days, this really is to keep precisely 1 calf/ cow/ 12 months. This ratio will get the best yield out of your cow and keep a good earnings margin pertaining to the farmer.
The cow will generate differing produces of dairy throughout the year; the yield will follow what is called a lactation shape as viewed below in diagram 2 .

Due to the high amounts of milk that the cow is generating at this stage of lactation there may be a reduction in human body condition resulting from the cow being in negative energy balance (N. E. B). N. Elizabeth. B is usually where the cow is not really receiving enough energy to generate milk without losing weight as it is using its very own body supplies to meet the necessity. The cow will reach peak dry matter intake (D. Meters. I. ) after around 70 days, this creates a time separation between the optimum yield with the cow as well as the peak G. M. I actually of the cow, this will result in a N. Elizabeth. B and therefore there will be a bad liveweight transform. Therefore the lack of body symptom in early lactation is necessary to let the peak dairy production to be produced.
