All livestock sectors are seeking to reduce imports of raw protein materials. Insect meals belong to the category of concentrated protein sources, but their nutritional characteristics are poorly documented and attempts to incorporate them into swine feed have been the subject of few publications.

From their respective academic and on-farm perspectives, Josep Gasa and Josep Casanovas comment on a recent study about the effect of postweaning feed intake.

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

The evolution of multi-site pig production over the last 25 years has not held true to its original intent.

Where would you begin to develop new and valuable information about your farm’s profitability (or lack thereof) that you are not monitoring now? Certainly, one of the most important ones is to visualize your data in a new way.

From their respective academic and on-farm perspectives, Josep Gasa and Josep Casanovas comment on a recent study regarding the effect of heat stress on sows: Which weeks does it affect the farrowing rate the most? What about the weaning-to-first-service interval? Are there differences depending on parity?

To have good gilt performance, producers and vets must value those gilts and invest accordingly. Dr. Clayton Johnson from Carthage Veterinary Services shares some tips about gilt productive development.

When productivity decreases, but productive efficiency is maintained...

In order to follow the evolution of the pigs at weaning and fattening, having a growth curve is very practical.

In order to apply the most suitable feeding regime to newly weaned pigs it is important to balance the trade off between the detrimental effect on performance of feeding levels of protein that are too low to allow maximal growth and those which increase the risk of post weaning diarrhoea.

A challenge in animal production today is to raise livestock within new environmental rules and regulations. Although most states in the United States regulate swine waste application based on N concentration, more are changing to P-based regulations.

Joaquim Segalés, professor at the Universitat Autònoma de Barcelona and researcher at the Centre de Recerca en Sanitat Animal (CReSA) (research centre for animal health), was one of the first researchers to discover PMWS and PDNS in Spain. He will be in charge of this section where every month articles will be published on the latest themes, especially from a practical point of view. These themes will include etiology, patogenicity, epidemiology, diagnostic, treatment and prevention of porcine circovirus-associated diseases. A possible hypothesis will also be presented on the emergence of porcine circovirus on a worldwide level.
