We propose a more direct indicator to look at and analyze reproductive problems on the farm.

The PigCHAMP Pro Europe database was used to analyze nurse sows, which wean almost twice the farm average.

Sows that try to recover after weaning no piglets have markedly lower performance and a significant chance of failing in lactation again.

We continue our comparison of production data between sow farms in Spain and the United States. This time we focus on replacement rate, pre-weaning mortality, and weaning weight.

A comparison of Spanish and U.S. main production numbers on sow farm

Each farm should analyze its historical data to quantify the effect of seasonality on its farrowing rate and prolificacy.

The incidence and distribution of small litters and factors affecting the number of piglets born alive on swine farms.

This second article analyzes data for the breedings done on weekday holidays in Spain in 2018, although the results can be extrapolated changing the dates for those holidays celebrated in each country.

This article compares the results of the inseminations done one week before the holiday, on the holiday, and one day after the holiday.

Does a high retention rate indicate high productivity?

Gilts have more returns to estrus... but why?

Which indicator best reflects performance - farrowing rate or non-productive days?

What is more important: the farm or genetics?

Is it worth to purchase hyperprolific sows for my farm?

It is not only related to NPDs, but it can also have a greater impact than we first thought.

One of the indices that is generating much interest is the one referred to the number of weaned piglets per sow lifetime (WSL). This index refers to the total number of piglets that a sow has weaned throughout its productive life.
