An Overview on the Use of Near Infrared Spectroscopy (NIRS) on Farms for the Management of Dairy Cows

Dairy farming is increasingly affected by the digital revolution. To respond to current challenges—such as environmental, economic, and social sustainability—new technologies must be adopted, entering perspective of precision livestock farming. This made possible development countless sensors adopted in barn. The technology that affecting various aspects dairy cattle breeding certainly near infrared spectroscopy (NIRS) which versatile can used online/inline evaluate control critical points production process PAT (process analytical technology). In barn, NIRS currently obtain information on chemical-physical composition raw materials, total mixed ration (TMR), feces digestibility, chemical technological analysis milk. All this a short time eliminating waiting times for response costs, allowing an improvement management. Many studies affirm validity reliable predictive against multiple relevant parameters matrices such feed, TMR, feces, review highlights usefulness farm with particular attention portable instrumentation usable directly farm.
