Post-pellet fat application to improve pellet durability

Good day Dr. Manangi,
Since I am very interested in this matter, it is possible for you to share the results of your study and conclusions?
Thanks

Dear Dr. Manangi,

I am also interested in the results of your study. Would be great if you could share with me.
Thanks in advance.

Good day Dr. Manangi

I'm strugling the same problem with our customers, when adding several feed enzymes with different matrix values. We often run into problems with the amount of oil in commersial feeds based on Corn / Soya. I have to set a minimum on, 0,5% ~ 5 kg per ton. but it then cause problems with the calculated energi level in the diet esp. in Pre. starter and starter feeds. This is simply getting to high!

What is your experience with this?

Very nice topic, we got good information.
Thanks.

Dr. Manish Kumar Shah Here is a message from Dr. Manangi:
Dr. Shah,
Thanks for your questions. Basically, we are trying to deliver the fat that needs to be in there. When we measured the fat content, it was close to the expected value. This confirms that there shouldn’t be any change in energy or protein values. Again, it is very important to have the right equipment to make sure the amount of fat is delivered correctly. If there is any variation in the amount of fat delivered or coated, then it would affect the fat content and hence the ratio of energy and protein. For the second question- In fact, the pellet durability was much higher for fat coated pellets than the pellets where fat was added in the mixer. Therefore, durability is not an issue and it would improve as shown in the poster.

Megharaja Manangi

Dear Elizabeth Davis
Greetings for the Day
I am in agreement with the post pellet fat application.
I have a few points which you can address if possible

The impact on crumbs after post pellet application of fat on fines and particle size. Does it increase feed intake in the chicks at early stages?
What could be the ideal temperature of fat/ oil at time of fat applications?
How the equipment are cleaned after post pelleting: most of the time the spray nozzles get blocked after application?
Does the fat application require additional antioxidants to prevent oxidation changes and rancidity or feed in high temperature open houses say more than 110 F?
Warm Regards
Dr. Sanjay Dronawat
