Performance – current stock

The profitability of a farm is determined to a large extent by the amount of milk that the animals produce in their lifetime (lifetime production). The milk yield per day of life is referred to as life effectiveness (LE). On average, it should be at least 15 kg of milk per day of life. The LE is determined jointly by the lifetime output, the length of the rearing phase and the useful life.

By evaluating lifetime performance, the reasons for the often too low life effectiveness can be quantified:

• When, how many cows leave too early, and for what reasons.
• Influence of first calving age on performance and effectiveness.
• Development of lifetime performance and life since 1 calving
• Relationship between lifetime achievement and fertility

The evaluation of the lifetime performance is carried out in 2 variants for the leaved animals and for the current living animal population.

The benefit is always calculated at the last valid MRec. It can be indicated by lactation and by age. This makes it possible to evaluate the age composition and performance structure of the herd as well as reproduction (proportion of cows in the 1st lactation).
