Genetics and reproduction

Photo 1. Heat control during the acclimation period is one of the key farm management aspects. It allows inseminating the gilt on its second or third recorded heat. It also allows knowing which gilts are not cycling properly.

Preparing the gilts: production

We talk about weight and age at mating, stall adaptation, flushing, how to perform heat detection and insemination, the convenience or inconvenience of segregating the gilts

The importance of lighting in your farm

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.

Abstract

A comparative study of the effects of Escherichia coli and Clostridium perfringens upon boar semen preserved in liquid storage

The effects of infection by E. coli were dependent of both bacterial load and storage period, whereas the effects of C. perfringens were mainly dependent on the bacterial load.
