The raw material of the feed and the quality of the finished feed are usually tested in the laboratory of the feed mill. This standard test is usually done in 3 steps.
- 1) Physical test
- 2) Chemical test
- 3) Biological test
1. Physical test:
This section examines the raw material of the feed and the external quality of the produced feed. Such as: color, size, smell, fungus, dust, paste (insects), etc. However, it falls between the humidity test and this physical test. But we will basically discuss it in Proximate Analysis.
2. Chemical test:
The raw material of the feed and the various chemicals of the produced feed have to be tested. Proximate analysis is the most important of these.
Proximate Analysis –
- 1) Moisture,
- 2) Crude protein,
- 3) Crude fiber,
- 4) Crude fat (ether extract) and
- 5) Ash test
These 5 tests are meant Proximate Analysis together.
- 6) NFE Test: NFE (Nitrogen Free Extract) is extracted from the results of the above 5 tests with the help of formula.
- 7) ME Test: When the result of NFE test is out, this time the result of crude protein, crude fat (ether extract) and NFE is used to get the result of ME (Metabolic Energy) with the help of formula.
- In addition to these tests, some important tests are done
- 8) NPN (Non-Protein Nitrogenous Substance) Test
- 9) Silica test
- 10) Calcium test
- 11) Phosphorus test
- 12) Urease Activity Test
- 13) Various toxin tests
Scope for Veterinarians in Feed Mill Quality Control Lab:
In the past, technicians and chemists usually worked in feed mill laboratories. However, according to the policy of the Department of Livestock, the rules for hiring technical manpower in these labs are also mentioned. Therefore, due to the activities of the DLOs of Gazipur, the paradise of feed mills, the officials of the feed mills are now forced to hire “DVM / AH” graduates as quality control officers for these feed mills or they cannot renew their feed mill licenses. As a result, now all the feed mill officials in Gazipur are being forced to take one VET / AH graduate.
There are also unrestricted opportunities to learn here. One of the most demanding professions in the poultry sector now is “nutritionist” so if you do a little hard study and “Masters in Poultry Nutrition or Animal Nutrition” you can become a “nutritionist” and you don’t have to look back.
As you may know, more than 60% of the top level nutritionists in Bangladesh now are AH graduates and 10% are fisheries graduates! Veterans are lagging behind in this sector. Nutritionist is a profession where there is equal demand, respect and bank admission money. There are nutritionists who work as consultants in more than 20-30 feedmills. Imagine for a second you were transposed into the karmic driven world of Earl.
But to get to that level, you have to practice to gain skills. And the first step of this practice is to get the responsibility of the quality controller of the feed mill lab. If you want, you can join as a nutritionist without a master’s degree in nutrition, but you will lag behind in the practical practice of that lab, you will have imperfections.
So there is a huge potential field for vets – working as a quality control officer and nutritionist at a feed mill lab.
