Default Esbilac® Manufacturing Change - Update

Esbilac® Manufacturing Change - Update
http://www.ewildagain.org/Nutrition/...te%20Alert.htm

Shirley Casey and Allan Casey, WildAgain Wildlife Rehabilitation, Inc.

Wildlife rehabilitators who feed Esbilac® to young squirrels in rehabilitation have noticed that the Esbilac® powder they have purchased since spring 2009 has a different texture and density than the product which they purchased in previous years. Many rehabilitators have said that they are using the new Esbilac® with the expected great results: healthy animals, good stool, and good growth rates. A few others, however, have reported gastrointestinal problems when feeding this ‘different-looking’ Esbilac® to infant and juvenile tree squirrels using proven protocols, particularly with younger, eyes-closed infants and juveniles.

Closer examination has shown that some of the GI upset has not been related to this new Esbilac® but a result of more typical causes (e.g., overfeeding in amount or frequency, coccidia, giardia, variance in mixing methods, product storage). Other cases, however, seem to have been influenced by the Esbilac® manufacturing change.

As much as we hoped to have a more complete article about the reasons, changes, and solutions by late August, it is taking longer to compile and analyze the information than expected. Knowing that rehabilitators want the information ASAP, here is some initial information. We will post more information at this website as it is available, and a longer article by October, 2009.

Same ingredients, different manufacturing

PetAg, Inc., the manufacturer of the Esbilac® milk replacer product, confirmed that Esbilac® ingredients and the nutritional composition are the same as they have been for years. PetAg did, however, change the manufacturing process for Esbilac® powder by returning to a single-step drying process in spring 2009.

Check the code on the package to determine if the Esbilac® you are using was manufactured prior to the processing change. If the package lot code is 3528E or higher, it was manufactured using the single spray drying process.

The single spray drying method involves less processing of ingredients when manufactured. This results in a product that, when reconstituted with water into a formula, provides a higher level of nutrients to the animal, since digestibility of the protein and fat increases by an estimated 1 to 3%.

This new Esbilac® weighs less and no longer is an ‘instant mix.’ PetAg recommends stirring for a full minute to mix it well. It needs to be mixed with very hot water. A poorly dissolved product could cause GI upset. Also, since the product seems to settle more in the can, turn the can over several times to ensure that it is not ‘compressed’ which can affect accuracy in measuring.

What formula ratio?

Many rehabilitators report that they are still using the standard 2 parts water and 1 part Esbilac® powder with great results. PetAg suggests that the rehabilitators who are observing GI upset use a bit more water than the Esbilac® container instructions of 2:1. Several rehabilitators who have mixed a formula of 2¼ parts water to 1 part Esbilac® reported that the problem resolved within a couple of days and they were then able to return to the 2:1 ratio. Some rehabilitators mixed it at 3:1 for several feedings when seeing problems, then reduced the water to 2½ for a few feedings, 2¼ for a couple, and worked back to 2:1. Strive for accurate measurements.

The squirrel’s age, health, and species may affect the animal’s ability to digest and utilize any formula of any strength. Experience will show what allows good digestion, overall health, and proper growth. As always, it is essential to monitor each animal closely for there could be individual differences in their digestion of any formula. Formula that is too dilute for too long could result in nutritional deficiencies that would affect health and growth rate.

These more dilute Esbilac® formula ratios, for those rehabilitators observing GI problems, are considered as early guidelines and are expected to change since this ratio is still being evaluated with young squirrels in terms of GI processes, overall health, and general growth and development.

Other PetAg product options

PetAg mentioned that many rehabilitators already use Zoologic® Milk Matrix 33/40 for their squirrels and report positive results. ZMM 33/40 contains the same ingredients and composition as Esbilac® except that the fat is from vegetable sources rather than the butterfat used in Esbilac®. PetAg also said that some squirrel rehabilitators report good results from using Goat Milk Esbilac® (GME).

Monitoring results

It is essential to recognize that it is still too early in the process to know the exact water:Esbilac® ratio adjustment to make in order to accommodate the change in PetAg’s change in manufacturing process, if at all. Additional adjustments in the ratio may be required for any changes based on species, age of animal, health of the animal, and so forth. Each rehabilitator should continue their normal practice of closely monitoring every animal’s health and development.

Continuing data collection

In the meantime, we will continue researching these issues and provide information on this website. We also will share our findings with PetAg. If you would like to offer observations on your experiences with Esbilac® that has been available since spring 2009 or ask questions, contact us at wlrehabproject@aol.com and include name, state, and phone number (we will not share this with others).

Another update from Chris at the squirrel store:

Esbilac Update!!

As many of you may know their have been some issues with Esbilac this summer. Initially it was thought that the Esbilac was too concentrated. It has actually been just the opposite. It has come to our attention that we need to actually bring the formula back into balance by adding an additional fat source.

Please keep in mind that this information is for squirrels only!
This source is listed below:

If you have Multi Milk on hand do this:
1 part powdered esbilac
1/2 part multi milk
2 part water

If you do not have Multi Milk please follow the following:
1 part powdered esbilac
1 part water
1/2 part good quality heavy cream

By using either cream or multi milk to add the additional fat you are also keeping the nutrition correct for squirrels. You should see a noticeable improvement within two days of following this information.

If you need to order Multi Milk you can find it here on our site. Please keep in mind that the Heavy Cream also works excellent.
To purchase Multi Milk click here.

If you are feeding Opossums the correct ration is:
1 Part Esbilac
1 1/2 Part Water
Whether or not the cream is needed should be discussed with the National Opossum Society.

If you are feeding skunks the following should be followed:
1 Part Esbilac
1 Part Multi Milk
2 1/2 Part Water

FYI! This esbilac information is coming from an extremely reliable source. This person specializes in squirrel rehab and if I did not trust this opinion than I would not be posting this informaion. I hope it helps anyone that is struggling with the esbilac situation. Chris

Hallo,

da mein Englisch nicht so gut ist, fällt es mir schwer das alles zu übersetzen.
Wenn ich es bisher richtig mitbekommen habe, wurde das Esbilac (Mit dem Westhighland-Terrier vorne drauf) nicht nur in der Zusammenseetzung geändert, sonden es gab auch Probleme mit e-coli und Klebsiella p Bakterien.

Viele Auffangstationen hier in Deutschland benutzen ja Esbilac. Bisher das alte Pulver (Golden Retriever Welpe vorne drauf)

Nun ist meine Frage:
Gab es eine Rückruf-Aktion?
Wie können wir erkennen, ob das Esbilac, welches wir hier geliefert bekommen in Ordnung ist. Nur anhand der Dose? Also... Altes Foto = alte Zusammensetzung = Pulver ok?

Würde ja gerne das Fox Valley füttern, aber das ist hier gar nicht erhältlich.

Ich mache mir echt Sorgen.... Es ist sowieso schon schwer dieses Esbilac zu bekommen...zumal es sschweineteuer ist...und nun auch noch dieses Dilemma!

LG
Suzie

Hallo Suzie,

also ich denke, es ist viel Wind um nichts hier, aber andre bestehen drauf, das Esbilac und auch sauer gewordenes KMR daran schuld ist, das sie soviele Tiere verloren haben dieses Jahr.

Ich persoenlich hab beide, altes und neues Esbilac, ausprobiert und hab keinen Unterschied in den Tieren fest gestellt. Mir fiel nur auf, das das Pulver selber etwas mehr malziger riecht.

Es gab keinen Rueckruf und der ganze Wind das soviel Metal in dem Pulver ist, ist auch falsch gewesen.

Im Moment koennen sie sich nicht mal einigen, obs jetzt konzentrierter als vorher ist oder nicht...also ich weiss nicht, ich selber hatte keine Probleme und habs normal wie immer mit Wasser gemischt.

Hello again,

dann verstehe ich aber nicht, dass PetAG einräumte, dass zumindest das KMR nicht in Ordnung ist. (Oder habe ich da was falsch übersetzt?)

"PetAg posted an announcement on its website that KMR®, their milk replacer for kittens, has had some problems develop. They tell customers to not use the product if it has a ‘bad odor.’ "

Ich fand halt beim googeln mehrere amerikanische Webseiten, wo vor Esbilac gewarnt wurde. Schade das ich die nicht abgespeichert habe..... dann hätte ich die Links hier reinstellen können.

Danke für Deine schnelle Antwort.

LG
Suzie

Thanks Bear! lol

Das mit KMR war das in den heissen Staaten wie Texas, California und Florida, das das Pulver beim versenden in ungeheizten Lastwaegen sauer wurde und das die das dann ersetzt haben, wenn man angerufen hat.

Huhu,

halte mich bitte nicht für penetrant *liebguck*

Aber in einem anderen Forum haben sie kurz in eine zip Datei von Pet AG gucken können (wenn ich das richtig übersetzt habe) und darauf hin haben sie folgendes festgestellt:

Zitat: "Wow! I can't tell you how excited I was to open that baby up. Quickly, I think we have one possibility as to why KMR kills:

half the fat and twice the protein of Esbilac/Multimilk

Not enough fat=starving babies. Too much protein=stress on organs.

Will definitely study this some more tomorrow."

Kannst du mir evtl. sagen, was es mit dem Esbilac für Puppys auf sich hat. Wurde einfach nur das Foto geändert, oder doch auch die Zusammensetzung?

LG
Suzie

Default Re: Esbilac® Manufacturing Change - Update

Ich hab ehrlich gesagt den Ueberblick verloren. Einer redet von Esbilac und meint KMR und umgekehrt. Die Zusammensetzungen wurden geaendert, ja, aber die sollten keine Auswirkung auf die Tiere haben.

Die eine Haelfte von Leuten regt sich auf, das zuviel Fett und Eiweiss drin ist, die andre Haelfte behauptet das Gegenteil und die Firma selber mit ihren Anwaelten, sagt nochmal was andres um ihren eigenen Hintern zu schuetzen.

Schick mir doch mal das zip von PetAG, ich guck mal was die so meinen. Wenns nicht zu lang ist, kann ich es ja uebersetzen.

Da findest du es.... Ich kann es nicht öffnen.

Mir geht es natürlich in erster Linie um das Esbilac. (Brauner Hund und weißer Hund vorne drauf. Ist da ein Unterschied...ja oder nein....
Hier in D kommt doch gar nichts an Info darüber an. Die wenigen Firmen, die das hier anbieten, interessiert das sowieso nicht. Ich wollte versuchen nur Dosen mit braunem Hund drauf zu kaufen.

Vielen Dank für deine Geduld!

LG
