Problems needing attention in chicken diet collocation
There are many kinds of chicken feed, what kind of feed is the main feed? How to match scientifically and reasonably with low price?
1. First of all, we must know what nutrients the chickens need. Due to the different requirements of all kinds of chickens, such as light laying hens, heavy laying hens or broiler chickens, chicks, big chickens or breeder chickens, the nutrition required by all kinds of chickens is not exactly the same in quantity and quality.
Query the corresponding data of species and size to determine the required nutrients.
2. It is necessary to know which type of locally produced feed is more, and the price is cheap and the source is abundant.
3. The matching diet can not only meet the requirements of chicken, but also meet the needs of chicken growth and development and egg laying, with good palatability and low cost.
4. When calculating diets, we must master the nutrition theory and practical methods of chickens, not only to calculate the cheapest feed, but also to calculate perfect diets.
5. The evaluation standard of dietary matching of chickens mainly depends on the feed reward. If the feed reward is high and the feeding date is short, the cost will be reduced.
6. The feed is better in the form of detritus. If it is too crushed, the feed intake of chickens will be reduced. The weight gain of low-energy pellet feed is faster, and the amount of pellet feed used by young hens should be limited to avoid overfertilizing before laying eggs. Adult hens had better use mixed powder so as not to eat too much and cause excessive fertilizer. But in summer, small
Caged hens can be used properly to increase food intake.
7. Different breeds and strains of chickens adopt different formulations, which cannot be stereotyped. During beak breaking, herding, transportation and disease of chickens, they should be fed the so-called fortified feed with good quality, vitamins and antibiotics to prevent the occurrence of diseases.
8. When determining the protein content in feed, we should consider not only the energy level in the diet, but also the balance of various nutrients. Such as protein and amino acid balance, crude fat and crude fiber content in diet, vitamin needs, mineral supplements, trace element antibiotics are generally added.
When the form of the agent is added to the feed, the matching diet can be considered perfect.
9. Moldy feed can not be fed to chickens, and its feed is easy to cause aflatoxin poisoning. Anti-mildew agent should be added to the feed properly.
10. there should be many varieties of feed combination, but there should be a certain proportion of the main types, and they should be well known when they are combined.
Cereal seeds account for 40%, 60%, 2 ~ 3 kinds of energy; bran, 10%, 30%, 1 ~ 2 kinds, providing energy and B vitamins; oil cakes, 10% 20% 1 ~ 2 kinds, providing protein; 2%, 8%, 2 ~ 3 kinds of minerals, used to supplement calcium and phosphorus; hay powder 3%, 5%. Animal feed 3% 15% 1-2 kinds to supplement protein and essential methionine, cystine, lysine; additive 0.05%-0.25%, adding vitamins and antimicrobial, anti-coccidial and deworming drugs in proportion; salt accounts for 0.3% and 0.5% of the diet.

Piglets have imperfect digestive function, hypoplasia of enzyme system, lack of innate immunity, poor digestion and disease resistance, easy to infection and affect growth and development. Generally speaking, the newborn piglets have strong resistance, rapid growth and development, and this characteristic has a strong heredity. Therefore, the litter selection must be carried out when the sows are selected, and the piglets with good development, many nipples and neat arrangement and good shape must be selected from the litter for breeding. In addition, in the same breed, large sows are better during pregnancy.
