The study concluded that single samples should not be relied upon to provide an accurate description of the feed, and substantial changes in diet formulation should not be done on results from a single sample. Duplicate samples taken on a single day reduced day-to-day variability, but the costs of sending multiple samples to a lab for analysis on a daily basis would not justify the added expense.
Precision for Every TMR Mixer Load
The dg precisionFEEDING system NIR Analyzer can be mounted in a payloader bucket to measure feed as it is moved from a concrete bunker or plastic storage bag. Each bucket is measured for dry matter content. Load weights are instantly adjusted to ensure the prescribed ration is constructed.
This NIR technology can be incorporated into a full feeding management system to aid dairy producers and their nutritionists. In addition to the NIR Analyzer unit, other pieces of the complete system includes a fully computerized feeding system that reads DM and nutrient values of forages, and automatically adjusts rations on the fly at the TMR; professional feed management software; and a remote control, high-tech weighing controller that wirelessly receives data from the NIR Analyzer.
With an on-farm NIR feed analysis unit, it is more feasible and cost effective to do multiple feed samples in a given day. The nutritional variances that occur in certain feeds over a short period of time can be identified and corrected immediately.
The end result is greater feeding-to-feeding ration consistency, fewer refusals and better management of weather events. Consistency results in improved overall cow health, and more milk and milk components. Some nutritionists have seen an additional 1 to 3 lbs. of milk per cow per day. Due to these benefits, payback for a portable NIR analyzer in larger dairy operations can be as short as 3 to 6 months.
