Small, delicious, low-class pigeons

The small, delicious, low-lying quail is a beautiful ornamental bird and a rare species with high economic value. Because of its unique qualities, CCTV has repeatedly covered and promoted the breeding of quails. **Nutritional and Medicinal Value:** According to the person in charge of Hulei Zhaobao Ecological Farm (Zip Code: 364116) in Yongding County, Fujian Province, quail meat is tender, flavorful, and highly nutritious. According to research by the School of Public Health at West China University of Medical Sciences, quail meat contains 30.1% protein, which is about 25% higher than that of pigeons and twice as much as ordinary chicken. Its fat content is only 4.2%, and it is rich in 18 essential amino acids, along with high levels of zinc, barium, and other trace elements. These nutrients help strengthen the kidneys, improve physical strength, and are beneficial for people of all ages. In ancient times, Li Shizhen, a renowned medical scholar from the Ming Dynasty, mentioned in *Compendium of Materia Medica* that quail can "nourish the five internal organs, benefit the heart, and enhance vitality." It was even called the "top nine chickens," highlighting its health benefits. Traditionally, it has been used to treat children with poor appetite, weight loss, and stunted growth. For nursing mothers, consuming quail can also support the healthy development of infants. **Economic Value:** The growth cycle of quails is short, with them reaching marketable size in about 70 days, weighing up to 0.8 pounds. Each quail consumes about 2 kg of feed, costing around 4-5 yuan. The current market price is about 15 yuan per bird. Adult quails can be raised for 180 days and lay 85-120 eggs per year—about 8-10 times more than pigeons. This makes their breeding cost much lower than that of pigeons. Under good conditions, one person can raise 100 groups (1 male and 4 females each), producing an annual output of around 5,000-6,000 birds, with an annual value of up to 60,000 yuan and a profit of 3,000-4,000 yuan. Quails have strong disease resistance and a very low mortality rate, making them a low-risk investment. Their profit is 5-6 times higher than that of chickens, ducks, pigs, and rabbits. Due to their small size and low price, they are affordable for every family and have become a popular dish in many households. Today, they are the most sold rare wild game in big cities across southern China. **Breeding Advantages:** Compared to pigeons, quails require fewer resources. While 5 hens need 5 cocks, only 1 male is needed for 5 females. This reduces breeding costs to just 1/4 of those for pigeons. A pair of pigeons produces 4-5 offspring per year, while a single female quail can produce 50-60 young annually. Breeding quails is not only cheaper but also more profitable, with profits 6-8 times higher than those of pigeons. **Feeding and Raising Conditions:** Quails are omnivorous, eating plant seeds like millet, wheat, and corn, as well as vegetables. They can be raised in both urban and rural areas, including vacant lots and warehouses. With 25-30 quails per square meter, raising them is simple and similar to raising chickens. They are more resistant than poultry and easy to manage, making them a great option for farmers looking for a quick and profitable project. **Market Prospects:** Due to their unique flavor and taste, quails have long been considered a delicacy, often served in the People's Hall to entertain foreign guests. According to surveys by relevant state agencies, annual consumption in hotels and households in Guangdong, Shanghai, and Beijing ranges from 1 to 150 million, but the supply is only 80 million. At a current price of 18-23 yuan per bird, there is still a shortage in the market. Because of their affordability, quails have a large consumer base, and demand is growing rapidly. Broilers and meat pigeons are gradually being replaced by quails, and their popularity continues to rise.

Roughness Profilometer

Roughness Profile Measuring Instruments all-in-one machine is an all-in-one machine for measuring profile shape and surface roughness, which has the powerful function of analyzing and measuring profile shape and surface roughness. Realize accurate measurement of dimensions, shape and roughness. It is mainly used to measure the parameters of the surface micro-geometry and macro-geometry of mechanical parts such as straightness, inclination, angle treatment, roundness treatment, double-groove treatment, double-arc treatment, etc.

Performance characteristics
1. High accuracy, high stability and high repeatability: meet the measurement accuracy requirements of the measured part.
1) Select high-precision grating measurement system and high-precision inductance measurement system, with high measurement accuracy;
2) Independently researched and developed high-precision grinding guide rail system, which has good wear resistance of guide rail materials and ensures stable and reliable operation of the system;
3) High-performance linear motor drive system ensures high measurement stability and good repeatability.
2. Intelligent management and detection software system:
The operation interface of the instrument is friendly, the operator can easily master the operation of the instrument, and the use is very simple.
1) The company has accumulated many years of practical measurement software design experience to provide customers with simple, practical and fast operation experience;
2) The company has invested many years of human resources in the development of instrument software, with special software copyright;
3) With powerful functions, it can automatically process data, print reports in various formats, and automatically display, print, save and query measurement records;
The data can be archived or printed in a centralized manner, which does not take up the verification operation time;
4) The measurement range is wide, which can meet almost all types of workpiece profile measurement, including special measurement functions of special workpiece screw, bearing, thread and other profiles;
5) The measured section can be selected automatically and manually for evaluation, and software functions can be customized according to customer requirements;
6) Powerful CNC automatic measurement and automatic labeling analysis function;
For large quantities of the same type of workpiece, it can carry out CNC measurement, automatically analyze and process the data, and carry out SPC statistics on the data, and can carry out statistical analysis in various ways to give quality control guidance;
7) It can automatically record and save all verification results by using computer large-capacity database storage.
3. It can also measure surface roughness and contour shape
With the same main body, you can only switch different modules to measure the profile shape and microroughness of the product.
