天然狗糧的兩大害處

I would like to discuss with you here in the dog food contains Menadione and Ethoxyquin harm, and I hope you can choose a dog for their own dog food.

But please remember that the world is not one of the best dog food, but some are more suitable for your dog's.

Menadione and Ethoxyquin natural dog food can be said in two hidden killers, they will accumulate in a little bit of a dog, the calendar month, the aftermath of the scourge difficult to estimate.

Menadione vitamin K3, no in-depth study of a friend, he said there is to see in the dog food recipe marked "" a source of vitamin K activity "or" vitamin K supplement "." What would not worry about it, who knows this Menadione Vitamin K3 is a cheap and harmful synthetic substances, for it is not correct because Menadione any Vitamin.

And Ethoxyquin This preservative is to kill a dog in the invisible, we also difficult to eleven traceable, see below.

Food containing menadione (Vitarmin K3) the risk
First of all, do not misunderstand, Vitamin K is not bad, Vitamin K is used to enrich the blood, usually anemic dogs, veterinary injections will inject Vitamin K.

Vitamin K1 is a natural compound (general source from Phylloquinone, plants, vegetables such as: broccoli, wave dishes)
The Vitamin K2 (Menaquinone, by a combination of bacteria and is reabsorbed by the body to digest a harmless substance)
But Menadione Vitamin K3 is a cheap and harmful synthetic substances, for it is not correct because Menadione any Vitamin.

Food containing menadione (Vitarmin K3) had previously studied the risk of two days and nights, I found a lot of natural dog food brands advertised, there menadione sodium bisulfate, menadione sodium bisulfite or menadione dimethylpyrimidinol bisulfite (Vitamin K3) of these substances, careful ah, right dog great harm.
These substances in the dog food package usually marked by the following text:

menadione sodium bisulfate
menadione sodium bisulfite
menadione dimethylpyrimidinol bisulfite
"A source of vitamin K activity"
"Vitamin K supplement"

To facilitate the drafting, we (including Mordanna original) or have it referred to: "Menadione" or "Vitamin K3" or "vitamin K3" or "VK3".

Why menadione This is bad?

Cause cytotoxicity in the cells of liver
Enzymes from white blood cells cause to reflect cytotoxic consequences of the formation of the foundation
Severely weakened immune system
Possible mutagenic effect
Damage to natural vitamin K cycle
No effect on coumarin derivatives, often due to the presence of mold contamination in commercial food (toxic when ingested)
Cause hemolytic anemia and hyperbilirubinemia, with large doses of only connection
The level of interference calcium (Ca2 +) of the body, is an important factor in the dissolution of fibrin
Directly containing toxic in large doses (vomiting, proteinuria), unlike natural vitamin K
Strengthen the organization and has been detected in eggs, meat and milk of animals in the supplemented with menadione derivatives
Lead to extremely sensitive skin and mucous membranes, common reason dogs scratching
Cause allergic reactions and eczema
Menadione (eg menadione sodium bisulfate, menadione sodium bisulfite or menadione dimethylpyrimidinol bisulfite)

About ago Menadione edible things to consider:

Study was not specifically approved by the long-term use, such as in pet food in

Pat banned in many European countries Menadione for human foods, based on it's side effects, including severe can lead to permanent damage and death

Food and Drug Administration banned the comprehensive vitamin K, because of its high toxicity

Vitamin K1 and K2 metabolism through the lymphatic system, the use of pancreatic enzymes and bile acids and regulated by the liver. Vitamin K3 is directly absorbed by the body and bypass the natural way 踁 animal body and metabolic systems.

Excerpts pet nutritionist Su Jingjing MSc, RD one paragraph:

We can be sure Vitmain K3 and its compounds do have some toxicity. Although the majority of non-ruminants should take more than 1,000 times before they need Vitamin K3 poisoning (according to the author of the information collected, but generally the use of Vitamin K3 voluntarily list the contents of dog food usually contains 5-10 times Dogs needed Vitamin K weight), but research indicates that dogs and cats do not have any long-term consumption of such weighty if Vitamin K3 how much health damage (because so far, the most similar findings indicate if a dog continuously 4-33 day taking 25-50mg / Kg body weight of Vitamin K3 will appear symptoms of anemia. Other relevant studies have eaten Vitamin K3 use chicken or mouse).

如何選擇狗糧？ 首要看成份!

Dog meat ingredients is very important.
With fresh meat as the main ingredients of dog food is better,
You can watch on the ingredients table columns:

The first one - meat (meat) names indicate, such as chicken, turkey, beef, etc.
Second place - meat meal (meal), such as chicken meal, turkey meal, etc.
Again one - MBM (meat and bone meal),
Then the next one is the by-product, such as chicken by product,
Even animal by-product (ie, animal by-products)
High quality dog ​​food should contain
(1) high-quality source of meat protein, but it must be labeled as what kind of meat, such as the only animal meat labeled as (ANIMAL MEAT / MEAL) or poultry (POULTRYMEAT / MEAL) did not indicate as to what kind of animal the meat can not be accepted (for example , marked as chicken party is the right choice).
(2) the first two rows of ingredients should contain one kind of whole meat source.
(3) untreated whole grains, vegetables and other food material, because untreated foods contain more and better quality nutrition and enzymes (meaning processing means processing).
Quality dog ​​food should contain a minimum amount (MINIMUM) of:
(1) food residue (FOOD FRAGMENTS), such as Saccharomyces meters (BREWER'S RICE), wheat bran (WHEAT BRAN), etc., these grains residue (can also be said cereal products) because of its low cost, inexpensive, many cat / dog food manufacturers will be in dry food contains at least one in order to reduce costs, be careful to buy, do not want to choose this kind of cereal by-products contain a variety.
(2) meat products. If all of the meat by-products as the main source of protein dog food words are not of high quality protein.
Quality dog ​​food must not contain:
(1) fat or protein sources collectively, such as animal fats. These do not indicate what kind of animal fats for (should be marked as chicken fat, beef tallow, etc.).
(2) artificial preservatives (BHA, BHT, ETHOXYQUIN).
(3) artificial coloring.
(4) sweetened hormone (SWEETENERS). As syrup (CORN SYRUP), sucrose (SUCROSE) and the like, to increase the quality of the poor taste of food.
(5) Propylene glycol (PROPYLENE GLYCOL), a toxic substance added to food to keep food on the "wet" feeling.
In the course of the test food, pay attention to:
1) changes in appetite: little change in a month in food-process will not change much;
2) changes in stool: After two weeks in stable stool softness, volume and odor should become normal, long grain some resilience weak dogs and adaptation period (high protein) initial defecation situation will not ideal, Then not too early to determine the suitability of dog food until a month after the conclusion over time, of course, require some aid to promote digestion of food and drugs during;
3) gum conditions: eye discharge should normally occur if the gum under the premise that health should consider whether overfeeding, food and natural food such as beef recipes these relatively high calorie food, the need to reduce Feeding Amount and with the heat of the drug until normal;
4) tone situation: no fishy taste, in the early food-if this is the case with the heat and need drugs to aid digestion improved, but after January without drugs should be normal;
5) fur condition: the skin is not a sudden outbreak of a large area of ​​skin disease or dry hair should maintain a certain luster, not suddenly dim;
6) Body Status: under the premise of healthy weight loss can not be significant, if the amount of body fat will have to reduce feeding.

According to observe these points, choose the best characterization of grain to do some long-term feeding choice.
Note! ! Long time no more than six months. Otherwise, the number of dogs in a variety of digestive enzymes in the stomach will be kept at a certain kind of dog food on the adaptation of the level, it simply is the stomach has been dependent on a single dog food, then food will be very difficult if the transfer, adaptation period will be very long, and In the usual feeding process will unexplained diarrhea, which dogs digestion and absorption of a comprehensive nutrition is detrimental.
