Market situation and points for attention of Black-bone Chicken
Black-bone chicken is one of the precious chicken breeds in China. Named for its black skin and black bones, it is famous at home and abroad for its high nourishing, medicinal and ornamental value. Its breeds are Taihe black-bone chicken, Chinese black chicken and so on. The feeding and management of black-bone chicken is basically similar to that of other chicken breeds.
I. the market situation of black-bone fowl
In recent years, with the improvement of people's awareness of health care, the market demand of black-bone chicken has increased greatly. At present, black-bone chickens are in short supply in most rural markets of our country, and the prices are rising. Therefore, if farmers seize this powerful opportunity to raise black-bone chickens in small or large quantities, it is believed that higher economic benefits will be obtained. However, in raising black-bone chickens, we must pay attention to the following points:
II. Matters needing attention in raising
1. Pay attention to the feeding density
Black-bone chickens grow more slowly than other chicken breeds, so it is necessary to ensure appropriate density requirements. The specific density requirements are:
The average weight of 30-day-old is 180 grams. The feeding density during the rearing period was as follows: 60 chicks per square meter at the age of 10 days, 40 at the age of 20 days, 30 at the age of 20-40 days, 18 at the age of 40-60 days, and 12 birds per square meter thereafter.
2. Pay attention to feeding and management
The breeding of black-bone chicken is different because of its different raising purpose. Therefore, in its feeding and management, according to its different feeding purpose requirements, pay attention to the following feeding management requirements:
1. Body condition requirements of breeder chickens: during the breeding period, if the black-bone chicken is used as a backup breeder, in addition to ensuring comprehensive nutrition, pay attention to prevent overfertilizing, so as not to affect the production performance of the laying period.
2. body condition requirements of commercial chickens: during the breeding period, black-bone chickens, such as commercial medicinal or meat black chickens, should not be restricted and fattened with high-energy and high-protein feed. Usually at the age of 100-150 days, the body weight can reach 0.75-1.2 kg, which can be sold by pharmaceutical factories and foreign trade, or listed as general broilers.
3. Prevent hybridization: strengthen the back-up breeding of black-bone chickens to prevent hybridization with other chicken breeds, resulting in mixed breeds, so as to ensure the purity of black-bone chickens and the economic benefits of raising them.

Matters needing attention for pigs to feed bean cakes
Bean cake is a high-quality feed for pigs, with fragrant flavor, pigs like to eat very much, but lack of vitamin D, carotene and calcium. Should supplement some carrots and bone meal, stone powder and other mineral feed. The amount of bean cake should not be too much, generally accounting for about 15% of the diet is more appropriate, more than 20% will often cause pig diarrhea. Therefore, the science of feeding pigs with bean cake, feeding the right amount, will play the role of high-quality fine feed, otherwise it will have the opposite effect.

Duck arthritis syndrome
1) The main symptoms. The joint swelling of sick ducks was mainly seen in hock joints, followed by knee joints, hip joints and toe joints. Swelling of joints, purplish red, hot sensation on palpation, local softness at the beginning of the disease, then gradually hardening, severe limp or inability to walk, reduced feed intake, gradual emaciation and increased mortality. 2. Preventive measures. The disease is associated with a variety of bacterial infections, such as Staphylococcus, Salmonella, Riemerella anatipestifer and so on. We should insist on "all-in" in feeding system
