Feeding technology

鹧鸪 omnivorous birds in the natural state of nature, good at flying, strong vitality and disease resistance, widely distributed in the world. In the early 30s, Americans introduced wild quail domesticated animals from India and are now raised as rare birds. The crickets currently raised in China are descendants of the Indian species imported from the United States. Under artificial rearing conditions, the average annual egg production was 100, the fertilization rate was over 90%, and the fertilized egg hatching rate and brood survival rate were all above 85%. The meat is thick, with fine bones and small internal organs. Muscle contains high protein and less fat. The meat is delicate and delicious, and it is a high-quality game tonic. In the event of a landslide in the heat of meat pigeon breeding, quail is expected to dominate the consumer market for rare birds. Now we introduce its breeding technology as follows.

First, the selection and rearing of nymphs The bred bred is the individual from the age of 13 weeks to 24 weeks before the laying of eggs and can breed immediately. There are significant differences in the breeding and management of this species at this stage. The following aspects must be achieved in order to ensure their value.

1?Selection: After the 13-week-old brooding work is completed, artificial seed selection is required. The selection criteria are: When standing, the body is required to be balanced. The shoulder is naturally inclined to the tail with a slope of 45 degrees. When walking, the pace is free, the action is flexible, and the weight is appropriate. The eyes are round and big, the width is short, the chest is wide, and the back and chest are Parallel; axillary hard and straight hair, moderate length, length 5-9 cm, toes complete and normal; feathers neat, with the characteristics of apes. After the seeds are selected, they are transferred to rearing facilities for rearing.

2. Breeding conditions during the rearing period: If you are reared for breeding, you must have a poultry house and a sports field so that you can eat and rest quietly, and you can fly and get natural sunlight. The stocking density was 15/m2; low-intensity light was applied for 14 hours per day and the brightness was 0.5 to 1 watt/m2.

3? Feed and feeding methods: Feed preparation should be reasonable, both to ensure its normal development and no fat. The feed formulation was: corn flour 42%, wheat flour 30%, soybean meal 17%, fish meal 5%, stone powder 4%, trace elements 1.5%, salt 0.2%, and additives 0.3%. In addition, 20 grams of multivitamins are added for every 100 kilograms of feed. The feeding amount is 30-35 grams per day, and the feeding is performed 3 times a day.

4. Feeding and management: Drinking water should be fresh and adequate, and the air in the house should be fresh. The catching shall be carried out after the lights are turned off at night. They shall be illuminated by flashlights and grasped one by one. Scratching during the day causes the entire flock to fly, causing severe stress and even death. The epidemic prevention program was: 1 week old chicken Newcastle disease II vaccine was intranasally administered, 10 weeks old intramuscular injection of Newcastle disease I strain vaccine, and 1 new chicken NDV vaccine was injected before laying eggs.

There is a conceptual overlap between plant extracts and herbal extracts. The raw materials of plant extracts in my country are mainly derived from Chinese herbal medicines, so domestic plant extracts can also be called Chinese medicine extracts to some extent.
