The artificially domesticated American pheasant is mature between 4 and 5 months of age. During the breeding season, in order to ensure the egg production rate, the passing rate of eggs and the fertilization rate, the following issues should be noted.
(I) Preparation for laying eggs
1. Level the venue. The ground of the sports ground is generally covered with 5 to 10 centimeters thick sand for group chicken sand bath.
2. Prevent disease. Thorough cleanliness and disinfection, and immunization of chickens against Newcastle disease in the spring, will lead to better selection of chickens.
3. Coops and sports grounds are scientifically equipped with breeding barriers to prevent cockerel courtship from fighting and serve as a habitat.
4. Nests are set around the house to reduce egg vibration and damage.
(B) timely gregarious breeding
The male-female ratio of the flock has a great relationship with the fertilization rate of the eggs. Practice has proved that the proportion of male and female hens is 1:6, and the fertilization rate of eggs is as high as 89%. In order to ensure that the male-female ratio is 1:6 during the breeding season, put the pheasant 1:4 to 5 at the beginning of the horticulture. During the breeding process, the roosters with the ability to fight and have no breeding ability are selected at any time, and the breeding roosters are no longer supplemented. In this way, the proportion of males and females remained at 1:6 throughout the breeding season. It can maintain the stability of the roosters and reduce the battle casualties caused by the adjustment.
(three) breeding environment
Pheasants are very sensitive to changes in the environment. Mutations in breeding areas, special sounds, and proximity to strangers are all unpleasant stimuli, which can cause frightening pheasants and fry groups. Therefore, it is necessary to do the following: First, it is not easy to change the breeder, the color of work clothes should be fixed, and the work procedures should be established. The second is to refuse to visit, which can prevent the disturbing of strangers and reduce the spread of the disease. The third is to catch chickens and set eggs to be light and steady, and to keep the flock relatively stable.
(D) Protection of "Prince Chicken"
1. After the male and female hens have joined together, a strong quarrel between the roosters will occur. After several days of fighting, the winner was the "prince chicken." Once the status of "Prince Chicken" has been determined, the flock will settle down, which will help increase the fertility rate of the eggs. Most of the "prince chickens" are good-looking, large-sized young male cocks. Do not take the "prince chicken" easily.
2. "Prince Chicken" often controls other cocks to participate in mating and affects the fertilization rate, which is a disadvantageous aspect. Set up barriers or partitions in the sheds and sports grounds, and hang up some branches, etc., and partition them into many areas to block the sight of the “Prince Chickenâ€, so that other cocks have the opportunity to participate in mating, increase the fertilization rate of the eggs, and reduce roosters’ deaths and injuries.
(V) Maintaining hygiene and reducing disease occurrence
1. Food troughs, sinks, and drinking fountains should be brushed once a day, disinfected twice a week, eliminated once a week, and the playing field leveled. Immediately after the rain, remove the stagnant water, keep it dry and ventilated, periodically kill insects and kill rodents, and properly dispose of dead chickens.
2. Observe the feathers, activities, spirit, appetite, and feces of the birds daily. Because these changes in appearance, are often reflected in the internal disease. According to the performance analysis of the cause, take timely preventive measures.
(6) The diet is full of nutrition and sufficient drinking water
1. Breeding and breeding of breeder chickens requires increased protein nutrition and attention to vitamin and mineral supplements. Appropriate vitamin C supplementation during the summer helps increase appetite and increase egg production. Hens require a large amount of calcium during the egg production period. If calcium deficiency is the case, the eggshell becomes thin and easily damaged. Therefore, calcium should be taken care of, but it should be suitable, otherwise too much calcium will affect the absorption of other nutrients, but also make The rough surface of the shell is not smooth and causes dystocia. With 2.9% of the feed, shell powder, or calcium powder can meet the needs.
2. Feeding time. The climate is cool in the morning and in the evening, chickens eat well, and the temperature is high at noon. The feed intake of chickens is generally reduced. It should be advanced in the morning and postponed in the evening. To feed less, use wet feeding method, you can also add some grass, vegetables and so on. In the summer, it is necessary to provide clean drinking water at any time.
(7) To avoid sunlight exposure in the dry season, take measures to reduce the temperature. The weather from mid-June to the end of July is hot, and direct sunlight will affect the cock's sexual activity, reduce the number of mating, and reduce the fertilization rate of the eggs. Therefore, if there isn't enough shade trees around the sports ground, you should cover the top of the stadium, spray water to cool down the sports field, and keep chickens free from heat, so as to maintain a high mating rate and fertility rate.
