Abstract:

The use of chemical methods in the determination of protein content in feed raw
materials is time consuming and costly. The aim of this study to determine the amount of crude
protein and crude fiber in mixed feeds using methods feed microscopy and chemical methods.
Cattle feed, cattle milk feed, lamb raising feed, and meat chick feed have been used to study
mixed feeds. By determining the results to indicate that feeds microscopy method approximately
how much closer to chemical methods. The percentages of raw materials of crude protein and
crude fiber in mixed feeds were determined with stereo microscopy and compared with obtained
results of chemical methods. As a result there is no statistically difference in crude protein
between feed microscopy method and chemical method. Feed microscopy estimating method can
be used instead of chemical methods for crude protein analysis. Also, there is an important
difference (P < 0.01) between two methods for crude fiber analysis, so that it is determined that
feed microscopy method cannot be used instead of chemical method. As a result, feed microscopy
method can be suggested because crude protein content in raw materials of feed is more
economical and shorter than chemical method.
