My friends, long time no see. Recently, I have received private messages from several friends asking if I have "abandoned my account". I would like to report to you today that I have not abandoned my account.

I am just forced by life, and I have been working hard to move bricks recently. Although the outdoor temperature has reached 35℃, the sun is very dazzling, and the bricks are extremely hot, but if life needs to go on, bricks must be moved!

In addition, some friends asked me whether the new model or the old model of Wilderness Feast is more worth buying! The reason why he had such doubts was because he had been buying the old model of Wilderness, but he saw a review that praised the new model to the sky, so he was confused. So what is the difference between this new model and the old model? Who has better value for money?

Today we will compare and discuss the Wilderness Feast Grain-Free Roast Beef Style - 28lb (old style) and the Wilderness Feast Grain-free Beef Style - 25lb (new style).

NO.1

Material comparison

The raw material lists of the two dog foods are as follows:

The top five raw materials of the old Wilderness are buffalo meat, mutton meal, chicken meal, sweet potato, and peas. The raw material list is not given. Information on the proportion of raw materials is given, but according to the principle of sorting the quantity of raw materials, we can also infer that there are more animal raw materials. In addition, potato protein and pea protein are also added to the raw materials. It is suspected that vegetable protein can increase the crude protein content. However, the ranking of these two proteins is very low, and the amount added is not much. At the same time, we also found in the raw materials High-end ingredients such as blueberries and raspberries.

Everyone has their own opinions on meat powder and fresh meat. Personally, I prefer meat powder. You must know that the moisture content of fresh meat is 75%+, which is about 4kg. Only fresh meat can be used to make 1kg of meat powder!

So recently we will find that the ingredient list of some dog food will mark you with "chicken meal*", and then tell you at the end of the ingredient list that "*" represents the proportion of water after restoration!

The top five raw materials of the new Wilderness are beef (53.46%), lentils (43%), tomato pomace, sunflower oil, and natural spices. We did not find the proportion of raw materials on the external website, but the Wilderness overseas The flagship store gives detailed proportions of raw materials, even accurate to the percentile!

This ingredient list is too simple and crude, but what I want to ask is, are these lentils dry or fresh?

In a certain evaluation, the evaluator defaulted to lean beef (protein content: 20.2%) and lentils to be fresh lentils (protein content: 2.5%). After some calculations, 91% of the dog food was found. % of the protein source is beef! !

But is this really the case? The secret begins! !

Assuming that the beef is really lean beef and the lentils are really fresh lentils, then 100kg of raw materials can only get 21.6kg of dry matter and 23.12kg of dog food.

The moisture content of tomato pomace is about 8%, and the moisture content of oils and other additives is very low, so we assume that the moisture content of 3.54kg of other substances is 6.6%.

According to the actual measurement results of a certain evaluation, the moisture content of dog food is 6.6%, so 21.60kg of dry matter (raw materials) can be used to obtain 23.12kg of finished dog food!

21.6/(1-0.066)=23.12

The protein content in the raw materials is approximately: 53.468*20.2%+43*2.7%=11.96kg

Then The crude protein content of finished dog food should be: 11.96/23.12=51.73%

Of course there is definitely a gap between theoretical calculation and actual production, but the gap between 51.73% and 27.3% (measured by a certain evaluation) is Isn't that too exaggerated?

In addition, we can also calculate the starch content:

According to actual measurements, the starch content of this dog food is 26.9%, and according to the raw material information, it can be seen that the starch in dog food is almost All come from fresh lentils. The carbohydrate content of fresh lentils is 6.1%, so the starch content should be less than 2.623kg (43*0.061).

So the starch content of dog food should also be less than 11.35% (2.623/ 23.12)!

But the measured starch content is as high as 26.9%!

Through the above two simple calculations, we can infer that 100% of the lentils in the raw materials are not fresh lentils, but dry lentils with extremely high protein content (up to 25%)!

Do you think this is the end?

Is the beef used in dog food really lean beef?

The pattern is broken!

Actual measurements show that the fat content of the new grain is as high as 17.2%, so the fat content in 100kg of raw materials should be greater than 3.98kg (23.12*17.2%). However, based on calculations based on raw material information, the fat that the raw materials can bring is only 3.08kg, 0.9kg lower than the theoretical calculation! So the beef is definitely not lean beef, but ordinary beef that is fat and lean, and may even be scraps!

If you don’t believe it, let’s review it!

The main nutritional components of beef (fat and lean) and dried lentils (Zhangye, Gansu) (checked in the 2017 version of the Chinese Food Nutrition Facts Table) are as follows:

So 100kg of raw materials can yield 59.10kg of dry Substance, 63.28kg of finished dog food. The calculation process is the same as above. If you have any questions, you can leave a message.

The protein content in the raw materials is approximately:

53.46*0.181+43*0.253=20.56kg

The protein content in the finished product should be:

20.56/63.28=32.5%

It is closer to the actual measured value of 27.3%!

The starch content in the raw materials should be less than:

43*0.554=23.82kg

The starch content in the finished product should be less than:

23.82/ 63.28=37.64%,

The measured starch content is 26.9%, which is consistent with the theoretical calculation!

The fat content in the raw materials is approximately:

53.46*0.134+43*0.004+3.54/2=9.11kg

The fat content in the finished product should be:< /p>

9.11/63.28=14.4%

Compared with the above, it is closer to the actual measured value of 17.2%!

From this we can also infer that the actual beef raw materials may be worse than imagined, that is, there is more fat. Only in this way can more fat be brought in, and the fat content can be increased to 17.2%!

In terms of additives, there are no suspicious ingredients in the new and old models, and the difference between the two is not very big. However, the addition of yucca extract in the old model may be more beneficial to improving the odor of feces, and the old model also has additional Taurine is added, but since we don’t know the actual taurine content of both, it’s difficult to know the real purpose of the additional taurine.

At this point, the difference in raw materials between the new and old models is quite obvious. Compared with the old models, the new model’s raw material list is simply more spicy!

NO.2

Nutritional value Comparison

Yellow is the old model, while gray is the new model. Don’t ask, just choose yellow for adults!

NO.3

Monthly consumption

Taking flagship store prices as an example, the old model’s event price is 690/12.7kg, and the new model’s event price is 695 /11.34kg!

According to the official recommended feeding amount, the monthly consumption comparison of a 20-pound (about 9kg) dog is as follows:

The new model costs 55 yuan more than the old model!

Choose the old style without a doubt!

NO.4

A very boring summary

Wilderness Feast is not very popular in China, but it is recommended by DFA (www.dogfoodadvisor.com) A frequent visitor to the list, it appears in almost every issue of DFA’s recommendation list. The main reason is cost-effectiveness! The price of the old model on the external website (www.chewy.com) is $46.54, and the new model is $52.24, which is equivalent to approximately 327/28lb and 367/25lb respectively in RMB. It is not too cheap! But in China, the price has almost doubled!

However, the price posted above is the price of the flagship store. It’s 2020, are you still superstitious about flagship stores? Wouldn’t it be nice to send him straight from the bonded warehouse? The price of less than 20 yuan per pound is simply too beautiful!

The purchase link will not be disclosed here. If you are in need, reply "20200728" in the background to discover low-priced sources!

But here’s what I want to say, although through calculation we found that the new Wilderness is a bean-based food with beef as the supplement, but it is not without its merits. For some dogs with allergic tendencies For example, if you need to check for allergens, it may be one of the options.
