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.

How does a sow's feed intake in the days prior to farrowing influence piglet birth and weaning weights?

Deviations from the sow's normal consumption pattern during the lactation phase have important production implications.

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.

There are casualties in the farrowing unit due to poor colostrum intake but, how many are there really? Are they just being classified as non-viable piglets?

The key lies in gilt management ...

Returns increase in a PRRS-positive farm in the middle of a census increase plus a change of management in the batch farrowing system, from 3 weeks to 1.

One of the main tools to encourage the installation of extra lighting in the mating area is the data analysis, and more specifically the weaning-to-service interval.

The article explains how to manage nurse sows in 3-week batch farrowing systems with a practical example.
