The grass chicken market is skillful and the benefit is high.

Grass chicken (also known as local breeder chicken) has wide adaptability, strong foraging ability, tolerance to rough management, and easy to raise. Its skin is thin and bone is fine, the meat is delicious, delicate, fragrant and delicious, it is a natural green food, favored by the majority of consumers. Judging from the current market situation, the listing price of live chickens is generally more than twice that of broilers, and the price per kilogram of eggs is about 5 yuan higher than that of imported chickens. Therefore, grass pheasant has become a major breeding project actively developed by many farmers. However, in order to gain weight quickly and come out early, some farmers feed a single concentrate feed throughout the whole period, ignoring the grass pheasant's instinct to eat grass. as a result, the feed cost is increased and the profit is lower than that of chickens equipped with roughage. With the continuous rise of feed price, in order to reduce feed cost, the author has proved that adding a certain proportion of green roughage on the basis of full price feed made of various concentrate can significantly improve the daily feed intake and disease resistance of grass chickens. only the average profit is 1.5 billion yuan more than that of chickens without green roughage. The specific feeding measures are introduced as follows.

1 feeding of grass chicks

After the grass chick house, drinking water can be given in 1 to 2 hours. When drinking for the first time, 5% glucose can be added to the water to enhance the physique of the chicken, relieve stress and facilitate meconium excretion. The water temperature is generally close to the temperature (16-20 ℃). At the age of 1 ~ 3 days after coming out of the shell, the chicks were fed mainly with concentrate, sprinkled with corn flour or chopped rice on the cloth or trough to allow them to eat freely. After 4 days of age, green and fresh vegetables or forage grass can be added to the concentrate. The feeding method is to mix the concentrate into a full price feed and then add about 20% of the green feed, feeding less frequently to ensure that the chick has sufficient feed intake to meet its needs for various vitamins. At this time, often feeding green feed can make the chicks form a good conditioned reflex to the food, laying the foundation for finding grass food in the pasture after getting out of temperature. The suitable density of henhouse per square meter is: 40 at 10 days old, 40 at 20 days old, 30 at 30 days old and 15 at 60 days old. This can not only make full use of the space of the chicken house, but also will not restrict the activities of the chicks and cause the air pollution and excessive humidity in the house.

The control of temperature in the house is the most important during the rearing period. The specific requirements are 33-31 ℃ at the age of 1 week, 30-25 ℃ at the age of 2-3 weeks, and 25-20 ℃ later. If the temperature in the house can not be reached, it should be heated properly. The relative humidity in the house should be 55% and 65%. In the first week after coming out of the shell, the light was 20: 23 hours a day, and the light was reduced to 16: 13 hours a day at the beginning of the second week, and then the natural light time was gradually used. In general, the light bulb is 2m from the ground, 1.52W per square meter.

(2) feeding during the breeding period

The breeding period of grass pheasant refers to the age of 60-130 days. During the breeding period, male and female should be raised in separate columns, with 10 birds per square meter in the chicken house, so as to facilitate management and reduce feed consumption.

2.1Roosters in the breeding period generally have a body weight of 1~1.2kg at the age of 100-120 days, which can be put on the market. In order to make the chicks meet the commercial weight requirements on time, they are required to be fed with full-price formula feed. Feed formula: corn 60%, bean cake 20%, wheat bran 10%, shell powder 6.5%, fish meal 3%, multidimensional, trace element 0.3%, salt 0.2%. Farmers with suitable conditions can adopt grazing and feed and supplement full-price ingredients in the morning and evening during grazing. If there are no conditions for grazing chickens, the ratio of green roughage to full price feed in the diet is 1 ∶ 1. The feeding method is to first feed the chickens with a single full price feed, and then put the same amount of green roughage in the bucket to allow the chickens to eat freely. 15 days before leaving the column, the feeding amount of green roughage can be appropriately reduced, at the same time, the feeding amount and proportion of full price feed can be increased, and the amount of green roughage can be reduced to less than 10%, which is beneficial to shorten the fattening period and increase daily gain.

2.2 during the breeding period, the feeding of hens should be restricted, mainly to appropriately reduce the proportion of protein and energy in the diet. Feed formula: corn 52%, bean cake 10%, wheat bran 15%, rice bran 14.5%, shell meal 7%, fish meal 1%, multi-dimensional, trace elements, etc. 0.3%, salt 0.2%. The management should be carried out at the right time, and the hens can be transferred to the laying house at the age of 120 days. If the flock is transferred at the beginning of laying, it is easy to produce stress reaction and affect the laying rate of the flock. The turnaround should be carried out in the evening to keep the chickens quiet as far as possible.

3. Breeding of laying hens

Laying hen feed formula: corn 58%, bean cake 20%, wheat bran 10%, bone meal, shell meal 7.5%, fish meal 4%, multi-dimensional, trace element 0.3%, salt 0.2%. The feed formula should be timely adjusted according to the egg production of chickens to meet the nutritional needs of laying hens. Every afternoon, sand can be put into the feed for chickens to eat freely to enhance the digestive function of chickens. The temperature in the henhouse should be kept at 13-24 ℃, the light time should be 14-16 hours per day, the light intensity should be about 2.5 W per square meter, and the chicken coop should be kept quiet.

4 to strengthen disinfection and epidemic prevention, the henhouse should be fully cleaned before entering the chicks, and then fumigated with formalin plus potassium permanganate (per cubic meter of space, 20ml formalin plus 20ml plus potassium permanganate 12g) for 24 hours, and the environment and appliances should also be disinfected with quicklime or fire alkali. Subcutaneous injection of Marek's disease vaccine at 1 day old, intramuscular injection of small triple oil emulsion vaccine (infectious bursal disease, Newcastle disease, infectious bronchitis) at 10 ~ 12 days old, chlorophenylguanidine (50g / 100kg feed, mixed well), intramuscular injection of Ⅰ Newcastle disease vaccine at 70 days old, and Newcastle disease oil emulsion vaccine at 130 days old. Antibiotics are usually given every 15 days.
