18-Feb-2022miguel-angel-de-andres-alvaroHello, it´s Miguel Angel, one of the authors. I completelly agree with you, economical and reproductive efficiency don´t match exactly, although is an indicator (a farm with very high reproductive efficiency usually is economical efficient too). And we work to earn money, not to produce more... Unfortunatelly, to get economical data is much more difficult than to get productive data.

Weaning-to-service interval: not only non-productive days
It is not only related to NPDs, but it can also have a greater impact than we first thought.

Piglets weaned per sow lifetime, the hidden index
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.

01-Mar-2019ZOOTECHvery accurate write-up. Can't be clearer. Production figures can be deceitful sometimes. It is practically the output per housed gilt/sow which practically measures the farm output in piglets actually sold, Return on investment of each housed gilt/sow. There is more to this, like piglet birth weight, weight at 21 days, weight at 25 days, investment in piglet( time & money) till these ages, actual age @ 25 kg live weight of piglet.
