1. Variety selection
To select high-quality yellow or jute feather broiler breeders that are recognized in the market, moderately individual, generally 180 days old, quail chickens weighing 2.4-2.9 kilograms, skin yellow, feet should be short, such as Guangxi Yulin yellow chicken, Xiayan Chicken, Guangdong Xinyi Huaixiang Chicken, etc. These varieties have unique flavors and are welcomed by the masses. They have large sales volume, high prices and good returns.
2. Castration age and feeding management before and after cutting
Castration period should be appropriate, castration too early, some males will remain after castration, which is what the masses called "half chicken"; later because of [illegal words are shielded] major surgery, but also easy to cause bleeding and death. The author thinks that no matter what breed, as long as more than 30% of chickens are crowned, barking, and stepped on the hen, they must castrate. During this time, it is imperative to do a good job of daily feeding and management to ensure the health of the flock. If a disease occurs, it will miss the castration period and cause loss.
A few days before the castration, the necessary immunizations should be completed at one time and the insects should be dewormed; the barns and playgrounds should be prepared and cleaned and disinfected. For each group of 300 chickens, the required area is calculated at 10 per square meter. The stadium should be wide and non-polluting, and there should be grassland and barren land and fruit trees as sports grounds to facilitate management. In order to prevent chickens from bleeding during castration surgery, vitamin K 35 mg per kilogram of body weight was added 3 days earlier in the feed to strengthen coagulation and increase resistance.
More than 10 days after castration feeding green feed, preferably artificial grass, such as ryegrass, and reduce the level of protein in the diet by 2%, can effectively prevent the "half chicken" generation. The pheasant has a long feeding time, usually 165 to 185 days before the slaughter, to save feed costs as much as possible during the breeding process. Pheasant weight gain has a strong compensation ability, as long as there is enough nutrition in the later period, regardless of the previous feeding conditions, they all reach the standard weight. If there are forest farmers and mountain farmers, the amount of livestock is small, and feeds for agricultural and sideline products such as rice bran, bran, rice, cassava, and corn can be used to feed the chickens in the field. Professional intensive breeding keeps the rations as low as possible. The general energy is 10.96 MJ/kg and the protein is 13%. However, vitamins should not be reduced.
The daily management must be meticulous, beware of thieves, especially the prevention of colds and respiratory diseases. Diseases not only affect growth, but also because chickens are affected by the medication and reduce the meat quality, so pay special attention.
After pheasant castration, chickens will be moulted gradually. When they reach the age of 135-145 days, they should pay attention to the growth of feathers. During this period, it is necessary to increase the protein percentage and energy level, and also to add high-quality fish meal, supplement zinc and manganese, and accelerate feather growth. In particular, the tail feathers and back feathers must grow well.
3. Simple method of cutting
One is enamel roasting chicken. First secure the rooster, remove the feathers around the glandular burr hole, use a pair of scissors to cut out the protruding portion of the glandular ester, and then use a lighted incense or red-hot round wire to apply heat stimulation to the glandular crypts. The stimulation method is Rhythmic intermittent stimulation, that is, stimulate it, immediately leave, then stimulate, and then leave, so repeated implementation, until the abdominal fat does not bleeding, the emergence of coke until.
The other is feeding traditional Chinese medicine castration. The Chinese medicine Schisandra and white pepper were given to the roosters. About 500 grams of weight of the roosters fed 1 Schisandra, white pepper, 12 grams each; adult roosters each serving Schisandra, white pepper, 18 grams each time, once a day, and even served 2 days.
After cocking by these two methods, generally, the cockscombs began to shrink about 7 days later, the feathers turned pale yellow, the males disappeared, and the roars stopped, and no fighting was found. It is recommended to use a small number of roosters for trials when castration. If it is effective and there are no side effects, perform a large number of operations.
4. Cutting operation precautions
The castration surgery was chosen in sunny weather. The operation is usually performed at 7-11 am. Feeding enough water after 23 o'clock in the evening before the operation, catching the chickens to be trapped on a cage, discharge them in a dark and shady place, and try to keep quiet so that the chickens are not frightened. Surgical movements are skilled, fast and accurate. After each chicken is fed a mixture of vitamin K, vitamin C, and Yunnanbaiyao (which can act as an analgesic, coagulation, and increase the resistance, to promote the early healing of the wound), and then placed in the prepared chicken house. The inside is covered with a layer of straw. Before and after castration can not mix groups and reduce fighting. Chickens have the property of red pigmentation. Chickens with bloody wounds must be stocked separately, or they are strangled. After 1 week, the chickens were released from the playground. After the chickens have been released, clean the grass and lay a clean, thick river sand. Do not use concrete floors in the homes. The weight of the chickens will cause scars on the soles of the feet. Pheasant market participants call it "bad feet."

Beautiful scenery and pleasant climate Ma Hao, the co-founder of the cooperative, has more than ten years of stupid chicken breeding experience. In 2009, he transformed into a breeding and promotion of pheasants and succeeded in filling the gaps in Shandong market pheasants, selling more than 150 days. Rooster chickens, all kinds of chickens, chickens and chickens are quickly chopped chicken trainees.
Since my field started technical teaching, people from all provinces who came to my field to study technology have succeeded in breeding pheasants and the market has responded well. The large number of pheasants raised by farmers in our field have also been slaughtered to the market one after another. We will develop the pheasant industry together with everyone in every place. We will respect the business philosophy of our partners and create a green product brand that consumers trust.
