The effect of age, interval collection and season on selected semen parameters and prediction of AI boars productivity

The possibility of planning the production level has a special importance for AI stations, and its inaccuracy should be minimized by eliminating the factors differentiating the quantity and quality of the ejaculate.

Genome-wide association study for sow lifetime productivity related traits in a Landrace purebred population

A genome-wide association study was performed to identify quantitative trait loci for SLP-related traits. A total of five genome-wide suggestive significant single nucleotide polymorphisms were identified.

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
