We talked to Jonatan Sánchez-Osorio, Technical Director of Topigs Norsvin Spain, about the essential points in managing sows from this genetic line.

What are the selection objectives of the Topigs Norsvin dam lines? Jonatan Sánchez-Osorio, Technical Director of Topigs Norsvin Spain, explains them to us in this article.

A systematic review evaluating the effects of inducing farrowing on stillbirth rate, birth weight, preweaning mortality, weaning weight, farrowing duration, and colostrum and milk characteristics.

Íñigo González explains the biosecurity measures taken in Hypor genetic nucleus and multiplication farms.

Use a waist bag to always have the supplies you need for farrowing assistance at hand.

In this article, we focus on the key aspects of management to optimize performance from this genetic line of sows. We talked with Carlos Martins.

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

Our series of articles on different genetics companies continues. This time, we talk about Hypor with Manuel Revilla.

In this article, we focus on the key management aspects for the optimal performance of sows with these genetics. To do so, we talked to Pablo Magallón, Technical Service veterinarian with PIC South Europe.

Starting with PIC, we are beginning a new series of articles on different genetics companies. For the genetic programme of PIC, we interviewed Juan Manuel Herrero, PIC genetic service manager for Spain and Portugal.

Identifying the different stages of farrowing allows us to monitor the process and take measures to maximize the number of piglets born alive and their viability.

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

Understanding the farrowing process and recognizing the signs for the different stages of birth, help us to develop management plans to improve the likelihood for live born piglets.

Currently, only the sperm-rich fraction is used. This article analyzes the possible use of the other fractions.

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.

Here's how ultrasound can be used to visualize ovarian structures, assess the state of puberty, and diagnose ovarian pathologies.

If my farrowing rate is low but I don't have empty sows or abortions, I must consider the culled pregnant sows.

The most frequent problems are reproductive and locomotive. What should I do if the percent among sows serviced is greater than 2%?

What could be causing abortions that are not seasonal and that are not affecting a certain phase of gestation in particular?

User responses of the 333 survey on gestation length in sows reveal gestations are trending around 115.5 days.

To conclude this series of articles, swine reproduction and artificial insemination specialist Javier Gil explains the importance of proper post-service management in terms of when to move sows and how to feed them.

What could be causing the abortions happening at a particular point in the gestation?

We continue with the series of articles in which swine reproduction and artificial insemination specialist, Javier Gil, gives us key points about proper management to improve fertility and prolificacy. In this article we will detail important aspects about semen doses and their storage.
