Chicken breeding technical knowledge

1. The positive role of reasonable feed control in chicken raising bai:

1. Reduce gastrointestinal burden. This is easy to understand. When you are hungry, the digestive tract, which is always running at a high load, can be briefly rested.

2. Promote digestive function. This aspect is also easy to understand, after starvation, the digestive function of the gastrointestinal tract is strengthened.

3. It is necessary to catch chickens during injections, eye drops and nasal injections or for immunization. Feed control for two to three hours can greatly reduce the stress of catching chickens. The mechanism of this aspect is that the main metabolism of the chicken body is digestion when it is full, so the blood volume in the digestive system is much higher than when it is fasting, while the blood supply of other systems is reduced, resulting in a decrease in anti-stress ability.

4. When food intake increases too fast after illness, proper feed control can protect the newly recovered gastrointestinal function from being damaged again. This situation can often be encountered in the actual breeding process, and the feed intake increases greatly after illness, and it does not increase after two days. .

5. Conducive to the discharge of stool. Stool refers to the feces accumulated in the intestine beyond the normal excretion time. Its color is generally dark green, black or brown, muddy and has a foul smell which is quite different from normal stool. Farmers know that chickens often excrete brown feces in the morning, commonly known as sugar chicken feces. Its essence is a kind of stool. This is the natural nature of chickens. Although broiler chickens have undergone years of breeding and improvement, this day cannot be changed. Sex. The longer the stool is in the body, the greater the damage to the body, and hunger is conducive to the excretion of stool.

6. Recently, scientists have discovered that when mitochondria in cells undergo oxidation, they not only produce ATP, an energy carrier necessary for cell metabolism, but also produce a certain percentage of peroxides, which can reduce the body's resistance. When starving, the ratio of ATP to peroxide produced by mitochondria increases, that is, peroxide decreases, and it can also produce enzymes that inhibit peroxide. The level of peroxides in the body decreases, and the body's immunity is enhanced.

2. How to control materials

1. The material control should be carried out randomly, and the daily material control time is not fixed. In the early years, I always believed that reasonable light control can play a role in material control. Now this understanding has changed. It is impossible to deny the effect of intermittent lighting. It is just that the chickens will quickly adapt completely after the intermittent lighting is implemented in the chicken house. There will be excessive hunger. So now I advocate irregular feeding control, the more irregular the better, so that the chickens will have more obvious hunger, and the health effects of hunger will be better.

2. The number of implementations of material control. Although feed control has many positive effects, it has a great promotion effect on health. If broiler chickens eat only 60% of the normal daily amount, the chicken flock will be very healthy, but the ultimate purpose of raising chickens is to make money, not to make money. The chicken is alive. Excessive control of feed will inevitably affect the growth and production performance of the flock. Therefore, it is not advisable to control the material too frequently, each time is one to two hours. In the broiler breeding process, how to control the light and how to proceed, the brooding starts from the third day, can be once every one to two days, once every two to three days in the middle stage, and once every three to four days after 30 days of age or not Control the material, but it is recommended to add material after all the material barrels are eaten up. Laying hens can delay the feeding time of a certain feeding time by one hour from time to time.

3. Material control should be done step by step. The first time to control the feed should be short and gradually increase. Allowing the chicken to have an adaptation process is the most fundamental way to avoid any stress.
