I. Deterioration of home environment The current restriction of broiler breeders is usually limited to quantitative feeding, which limits the intake of protein and energy by controlling the amount of feed. In this case, chickens that have been controlled by about half the chicken's feed intake are interested in drinking water. A large amount of drinking water and water from the neck feathers can easily cause dampness in the bedding. Therefore, we should do a good job of environmental control.
(1) Limit water to chickens except for high temperature Seasonal feeding day 1 hour before feeding 1 hour after feeding 1 hour after feeding No feeding 3 hours of water supply 1 hour each time; (2) Attention to draught The litter does not allow the feces to accumulate and ferment; (3) Strengthen the management and maintain the health of the flock to avoid diarrhea. Add some antibacterial and health-care drugs in the feed.
Second, triggering nutritional deficiencies for the restricted breeding breeder If you still add conventional ingredients such as vitamins, minerals, and other essential ingredients for growth and development of chickens, feeding due to insufficient intake will inevitably cause some essential substances to be consumed for a long time. Can cause a series of nutritional deficiencies.
The following points must be taken into account when preparing the feed for rearing breeder chickens:
(1) Select high-quality additives; (2) Increase the amount of additives such as vitamins can increase by 30% on a normal basis; (3) Ready-to-use feeds now; (4) Double the amount of vitamins and minerals when stressed.
Third, the use of drugs to reduce the effect of the general use of drugs is based on the normal intake of chickens and other factors derived from the limit of the feeding period if the normal drug concentration of the drug additives to the feed due to reduced intake of lead drugs Absorption decreases so that the treatment and prevention of drugs can not play a role in causing certain diseases. Therefore, the use of feed-shaking drugs should be increased by 30% on a regular basis or temporarily changed from feeding to free intake.
Fourth, rushing to eat caused the flock to die for swell and death. Feeding period The breeder tends to show a strong sense of hunger after a long period of time, especially if it is not fed. Feeding should be speedy. Feed the feed in a short period of time and try to supply enough water before feeding when the light is not visible. The water should not be far away from the trough. In this way, the occurrence of bloating can be avoided.
Problems in Restricted Feeding Stage of Breeder Chickens
Limiting rearing of broiler breeder chickens during the rearing period can prevent chickens from excessive fat deposition and maintain optimal body weight. However, the restriction of feeding will also cause some adverse effects on production and should be taken seriously and resolved.
