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?

Is this possible that after top up of oil in finished feed that could adjust the energy and protein ratio? Another one is the texture of pellets strength?

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.
Regards,
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

Dr Sanjay Dronawat Thanks for your interest. Below are responses from Dr. Manangi. Message me with your email address if you'd like me to send you the abstract and poster associated with this research.

1. Impact on crumbles: Based on our work, the post-pellet fat application helps to reduce the percentage of crumbles since it improves pellet durability as mentioned in the poster.
2. Does it increase feed intake?: We haven’t fed these pellets to chicks and can’t answer that question directly. However, I would say it should not increase intake as long as the right percentage of fat is delivered.
3. Fat temperature at the time of application: Maintain the minimum temperature (if needed) just enough to maintain the fat in flowing condition. That could go be about 65F (about 18C) depending on type of fat used to maintain its flowability.
4. Cleaning equipment after fat application: Suggest to discuss with equipment manufacturer on this question. They might be able to help with answering clogging issue.There are various technologies available for this purpose and those issues should be taken care.
5. Use of antioxidants to fat: In general, it is good to stabilize the fat to prevent it from becoming oxidized. Also, may want to consider adding antioxidants to feed as a preventative measure depending on economic feasibility and regulatory limits, if any.
