Low-cost chicken has a coup

Adjusting the feed formulation In actual production, the high egg production peak can last more than 4 months, and high-level feed nutrition should extend the maintenance time appropriately. After that, the use of high-protein feed should be reduced according to the decrease of egg production rate to avoid nutrient waste. When the flock is immunized, divided into groups, transferred to groups, and cut off, the vitamin content and protein level in the feed may be appropriately increased.

Less feed to the ground Tim feeding each time does not exceed 1/3 of the feed tank, try to let the chicken feed the feed tank and then feed, prevent the remaining feed mold deterioration.

The timely and correct deafness test showed that the chickens cut off were more than 6% cheaper than the continuously chopped chickens, and the experienced workers could be arranged to cut off the laying hens 7 to 9 days old.

Elimination of adverse individuals usually pay attention to the observation of chickens, found that diseased chickens, weak chickens, low-yielding chickens, discontinued chickens should be eliminated in time. This type of chicken generally accounts for 3% to 5% of the total number of chickens. Each additional year of breeding consumes 100 grams of chicken per bird. Some chicken farmers are often not able to eliminate the determination, resulting in a waste of feed. The breeder must have certain experience in raising chickens to eliminate the “fare-eating chickens” accurately: crowns, pale faces, hens with atrophic crowns and yellow legs should be singled out, and the phalanges of normal laying hens should be 3 or more fingers apart. With a space between the sternum of more than 3 fingers, when the peak of egg production was over, some chickens were found to have less than 1.5 fingers from the phalanx and less than 2 fingers in the transverse ridge. Overweight or overweight hens should be eliminated in time; the abdomen was enlarged and the abdominal cavity was stagnant. Or keep more liquid, hens inconvenient to walk away.
