How to wake the hen hug

First, the reasons for the hen hug

Many local breeders and breeders based on this breed have a considerable degree of brood behavior, which is an instinct for the reproduction of birds. The hen's brood is controlled by the physiological endocrine. When the prolactin secreted by the anterior pituitary gland increases, the ovaries shrink and the brood phenomenon occurs. In addition, the hen's brood sex is also affected by environmental conditions. Generally, there are nests in the late spring or summer when the temperature of the environment rises gradually and the amount of eggs produced is too large. In the egg-laying nests, too much eggs can induce the hens' nests. In the free-range state, the nests of the hens in the cockerel group are more serious.

During the hug period, the hens stop laying eggs and generally last for 2O days. The long ones can reach 1-2 months, affecting the economic benefits.

Second, hold measures

(1) Change the external environment:

Keep the coop quiet, well ventilated, well lit and free of vignetting to ensure that light can be sufficiently injected into the nesting box; increase the number of eggs to be picked up to prevent the eggs from being stored in the nest for too long; check the nests in time If there are snag chickens to seize the isolation, take appropriate waking measures.

(B), physical hold method

1. Use a sterile scissors to cut a small spot on top of the tail of the tail and 3 cm from the tip of the tip of the tail gland to apply salt; also use a sterile needle to vertically punch the tip of the tip from the tail. Point 3 cm at the tip of the small protrusions until the acupuncture does not go in, and left and right twisted several times, needles during the day, the needle out in the evening, back into the flock, and effective for 2 days.

2. In front of the center of the two-pallete palm of the chicken, use a sterilized coarse sewing acupuncture to stimulate the stimulator to hold 6mm deep and 1-2 times a day.

3. Close the cages. Hold the broodicks in the cages with the troughs, sinks and bottom nets. Place them in a well-lit and well-ventilated place to ensure that the chickens can drink and eat normally. You can't squat inside, and you'll wake up after 5 days.

4. Wash the hens in cold water with cold water and rinse them repeatedly to make their feathers wet. Once a day, wash them for 5 days. Most broody hens will be able to wake up.

5. Tie up the hen's feet with a tie and hang it upside down and hang it beside the chicken cage. The waking process is longer and causes the hen to develop stress and achieve the objective of rousing.

6. The nose-inserted feather pulls out one chicken feather and is sized to pass through the septum. It punctures from one side to the other. The broody hen will lose her mind because of foreign matter in her nose. .

7. Hang up one leg of the hen's hen and half of the hen so that the chicken's legs are uneasy and startled. A red stripe on the tail of the chicken makes the chicken terrified and nervous.

(III) Food awake method

1, irrigated vinegar: to Baowo chicken in the morning when an empty stomach to irrigate vinegar 5-1O ml, once every 1 hour irrigation, even irrigation 3 times, 2-3 days to wake up.

2. Every chicken is fed with 25-35 dry beans every day. Each day, morning and evening, it is filled with 1 time for 2 days. (The bean expands after the bean enters the crop and causes the hen to feel uneasy. It automatically leaves the nest, and the rich nutrition can promote the chicken. Restore egg production as soon as possible.

3. Gave 3 tablespoons of white spirit to each swine chicken to promote drunkenness and wake up after drinking.

(d) Chemical drug law:

1. Feeding pain tablets: On the first night after the chicken began to w

One more tablet will be fed on the day. If it is just “squeak” and does not hold the nest on the third day, you can stop taking medicine.

If you are still in a brood on the third day, you can add one more serving. Generally, you can hold it for two to three days.

2. Feed Rami seal: Feed each chicken 1 slice of Rami (isoniazid) daily, every other day, usually

Use 2 times to wake up.

3. Oral aspirin: Let hens take oral aspirin 1 tablet at the beginning of the mouth, every day 2

Times, even for 3 days, you can wake up.

4. Injection of copper sulphate solution: 1 ml of 20% copper sulfate solution injected intramuscularly into each swine

Once a day, even for 4 to 5 days, to promote the secretion of hormones in the anterior pituitary, enhance ovarian activity

Move without holding a nest.

(five) Hormone injection

1. Testosterone Propionate Injection (containing 1O, 25, and 50 mg per milliliter) is a good woke-up drug. Chickens weighing 12.5 mg for 1 to 2 kg, 25 mg for 2 to 3 kg, and 1 to 2 days after intramuscular injection, the swaddling chickens can quickly leave the nest and can quickly recover their eggs. For hens that have had nests for several days, the use of other methods tends to be less effective, but it is also often effective after one or two injections of testosterone propionate. If the amount is insufficient, the effect is poor, and even after 1 to 2 days, the nest is re-introduced. At this time, supplemental dose can be added for the second injection. If the dose is too large, besides waking, the hens will show a male response, vocalization and behavior similar to that of a rooster, but disappear spontaneously within 2 to 4 days.

2. Injecting triple hormone: An oil-soluble injection made up of testosterone propionate, progesterone, and estradiol benzoate. Each swine chicken was injected intramuscularly with 0.5 to 1 ml. If the effect is not obvious, the second injection every 3 days, generally 2 to 3 weeks after waking, can restore egg production. It should be noted that improper application of this method can affect fertility and egg production.

Third, the comparison of waking methods

The physical hold method: simple and easy, but the effect is not ideal. Waking up for a long time, most of them have to go through 5 to 6 days. At the same time, they are labor-intensive and inhuman to chickens, and are prone to induce other diseases.

The chemical drug method also has the disadvantages of high labor intensity and inconvenient operation.

Hormone injection method is simple, effective, and effective, but the one-time investment is relatively large. It is suitable for farms with large-scale free-range breeding and a large number of swaddling chickens.
