There are many reasons why growers should consider improving their herds. Increasing efficiencies can decrease your enterprise's outlays; improving breeding programs can increase your profits; and producing a product that is more desirable to consumers creates more demand for it.
Performance testing - program variations
The effect of reduced-effort variations to on-farm performance testing on genetic improvement in a pig herd
Replacing breeding stock
Information about replacing breeding stock to maximise your profits. There are three alternatives - buy in all stock, buy in boars (animals or AI), or select all from existing on-farm stock.
Using genetics to improve your herd
Using genetics can improve pig herd performance and is valuable for developing desirable traits such as growth rates and carcass fatness
Heterosis in pigs
Types of heterosis, and a guide to calculating and expected values from crosses
Inseminating sows (AI)
The technique for artificially inseminating sows on-farm using fresh or chilled semen is presented.
Selecting breeding stock from pigs on-farm based on growth rate and backfat thickness
Collecting semen from boars
Boar semen collection is commonly done in closed herds where, for health reasons, it is unwise to put introduced boars with the herd.
