Fat digestibility and bile acids

TJ Wang my direct mail is marchenkov150@gmail.com

The digestibility of fats &oils depend on many factors 1.the age of the bird 2.healthy microvilli in upper intestine.3.the chain length of the fatty A.4.the number of double bonds of fatty A.5.the form of fat either triglycerides or free fatty A.6.the ratio of unsaturated to saturated fatty A.

Hi Fatai : You mentioned tow reasons for high mortality in your layer flock one CRD and the other high body weight(too much fat) we can talk about each one separatly . 1- CRD - the disease is not so fatal as you told about your flock ,the disease agent mycoplasma may be transfer from breeder flock to day old chick or flock be contaminated in rearing or production period ,CRD in layer flock mostly affects rate of production and no high mortality . if your flock is CRD positive you must treat it by antibiotic to reduce its affect on production and mortality .CRD isnot the cause of too much fat of flock . 2- The other problem you mention is accumulation of too much fat . too much fat in abdomen is because of imbalance feed when the energy is higher than the need of layer , it finally causes a syndrome called "FATY LIVER HEMORRAGIC SYNDROME" that induces high mortality in layer flock especially in hot season like summer . you must prevent it by prepare balance feed in energy and amino acid and mineral also you most weigh you hens randomly every week to mange its variation in increase or decrease of weight , good oil and fat in feed is necessary to prevent FLHS .

George Entz Thanks a lot, very good!

Thanks for the great fat digestibility overview. Dear Dr. Marchenkov, would be possible to modulate a microbiota profile toward a better fat digestability?

could i get your prespective on how much is the max amount of canola oil you would add to a layer pullet prestarter diet 0-10 days, with and without added bile

Thank you for your quick response I will send the recipe to your e-mail. Regards

Yes Am interested in this topic because last year my laying birds had problems they were just dying in large quantities every day. Then I called a vet doctor to check reason why they are dying. After carried the check he discovered they had too much Fat and CRD. Then he describes some drug for it at long run I loose them all. Later on we heard that there was an outstanding break of a diseases called Avian influencer. Which we were told that no drug can cure it around the world now. Please I would like to know what we do to reduce fat and CRD in laying birds to allow them lay very well and equally stop their dead. Thanks

Thank you Dr for the educative lecture
