Topigs Norsvin has routinely used near-infrared spectroscopy (NIRS) technology in its pig breeding program for 18 years. In our experience, this method is very accurate and has generated considerable value for our clients due to sustainable breeding for high meat quality.
From the outset, we trained our own researchers in the use of NIRS technology, which meant we could develop our own methods, including calibrations, for both fat and meat quality traits.
Our studies show that it is possible to establish simple routine methods for measuring the quality of pig fat, as well as using preparation methods and instruments that are safe, user-friendly, environmentally friendly, and do not require chemical solvents. The results reveal that several parameters for meat and fat quality can be predicted with NIRS technology, and our work documents the use of NIRS-predicted values in the estimation of genetic parameters for breeding purposes.
The high heritability obtained clearly shows the power of NIRS and the high predictive capability of the calibrations developed.
For Topigs Norsvin, NIR technology has been every breeder’s dream, with fast and reliable measurements, low costs, and high prediction accuracy. Over the past 18 years, measurements have been made on the fat and meat of 50,000 animals. The data acquired have made it possible to breed for intramuscular fat, specific fatty acids, and iodine value as a measure of the fat’s technological quality.
