Treat H7N9 and Chicken Farming Rationally

Over the past two weeks there have been a number of people infected with the lesser-known H7N9 virus in China. H7N9 is a serotype of the species influenza virus A (avian influenza virus or bird flu virus). H7 normally circulates among avian populations with some variants known to occasionally infect humans. Now patients infected with H7N9 are increasing. The exact infection source has not been detected but H7N9 has caused great damage to poultry industry especially chicken farming.

H7N9 Affects Chicken Farming

The H7N9 flu is detected in some poultry samples but the varieties of birds are wide and poultry is just a few varieties of the birds so it is not scientific to simply think the source of H7N9 flu is poultry. The direct influence is that people don’t eat chicken and kill chickens. This is unfair for farmers especially the poultry practitioners and causes unnecessary damage to chicken industry ant the whole industry chain.

Now for the chicken farming the breeders should take measures to prevent H7N9 flu. Improving chicken’s immune system is an important preventive measure. Feed is the material foundation and the main source of energy and nutrition for chicken growth and reproduction. Only the good feeds can increase the chicken’s immune system to prevent diseases. Feed pellets is ideal for raising chicken. It is produced by adopting scientific formula, mixing a variety of raw materials evenly according to a certain proportion and a series of processing. It has balanced nutrition for chicken farming. And during the pelletizing process liquid nutrition can be added to improve disease resistance. The good environment can reduce the chances that chicken are infected with H7N9 flu. The chicken feed pellets which have cylinder shape and do not produce dust are good to the living environment.

What should be Noticed When Choose Aquafeed Raw Materials?

1.You can consider amino acid as one of the raw materials first.

2. Combining with local resource, confirm the raw materials varieties within 10.

3. When select protein material, you can take lysine and methionine unit prices as purchasing standard, but not the unit price of protein.

4. Don't use soybean meal or sesame meal with burnt appearance and smell, for lots of lysine is destroyed.

5. Fish meal is the main raw material of animal protein. You must analyze its amino acid before using.

6. Avoid using meat meal in hot seasons. The fat is easy to be oxidized and cause liver disease.

7. Silkworm chrysalises are easy to be oxidized for its high oil content. Test their freshness before purchase.

8. Blood meal is suitable for extrusion and spray drying technology for its low digestibility.

9. Wheat is better than wheat middling, for it can avoid adulteration and ensure the freshness.

10. Use zeolite powder, not stone powder.

11. Choose bean oil, rapeseed oil, edible lard or chicken oil for freshwater fish feed formula. Don't choose fish oil.

12. Feather meal processed by good hydrolysis process can be added into the formula, but not exceed 3%.

13. If choose outsourcing premix, check carefully.

14. Amino acid composition coconut cake and grape cake is not so good, you'd better not use.

15. Using microcapsule amino acid is a trend in aquafeed processing. It's the key of the production effect that whether the amino acid can tolerate high temperature tempering.

16. Don't purchase or add table salt.

17. The blood-cell protein must be all-broken, or it has no value.

18. Notice the aflatoxin and other hygiene indexes when purchase peanut meal.

Raw Materials for Aquafeeds

Common basic raw materials to the manufacture of most aquafeeds are similar to those employed in the manufacture of other types of animal feeds. However, it should be noticed that aquafeeds should avoid the use of high levels of plant or vegetable fibers and carbohydrates which are poorly digested and transformed by fishes. Raw materials for aquafeeds include cereals (maize, wheat, barley, rice, oat etc.), cereal by-products (wheat flour, corn bran, wheat bran etc.), meat meal, fish meal, shrimp meal, squid meal, blood meal, poultry by-product meal, (full fat) soybean meal, other vegetable protein meals, fats and oils, vitamin and mineral premix, salt, stabilizers and binders etc.

extruded aquafeed and raw materials

The major components of aquafeeds are protein (plant protein, animal protein and single cell protein), starch (sinking aquafeed consists more than 10% and floating aquafeed consists more than 20%), crude fat, raw fiber, crude ash and micronutrients.
