Local chickens, also known as "grass chickens" or "stupid chickens," are free-range broilers raised in mountainous forests and orchards. These chickens are highly valued for their tender meat, rich nutritional content, and the fact that they are raised without pollution. Their eggs and meat are considered green food, which has made them increasingly popular in recent years, leading to a steady rise in prices.
1. **Site Selection**: The chosen area should be far from residential zones, industrial areas, and busy roads to ensure a quiet and clean environment. It must have access to clean water sources such as unpolluted streams or ponds, and the air quality should be fresh and uncontaminated.
2. **Shed Construction**: In southern regions, it's best to build simple chicken coops on flat, sheltered land using materials like bamboo, canvas, or linoleum. The coops should face north-south for optimal ventilation. Plastic sheds can also be used to provide shade and protection during hot days. In northern loess plateau areas, natural caves can be adapted into shelters, with elevated chicken frames built for nighttime rest.
3. **Stocking Scale**: A reasonable stocking density is about 2,000 chickens per forest area. Large-scale operations can be difficult to manage, while small-scale setups may not be economically efficient. It’s best to stock chickens from late spring to mid-autumn, as cold weather in winter reduces their activity and appetite, making it unsuitable for raising.
4. **Rearing Methods**: Choose disease-resistant, strong breeds for rearing. For the first 34 days, they should be raised indoors with proper insulation. After that, they are gradually introduced to the outdoor environment. Initially, the chickens may not know how to go up the mountain, so training is essential. Two people usually work together—one whistles and feeds them, while the other uses branches to guide them uphill. This process is repeated daily at noon. In the evening, the same method is used to teach them to return home. After about 10 days of training, the chickens develop a conditioned response to the whistle and become more independent.
5. **Important Notes**: During the first few days after moving to the mountain, you can add a small amount of vitamin C or a multivitamin supplement to their feed or drinking water. For the first three months, no antibiotics or deworming medications are needed, as the chickens are raised in a natural, healthy environment.
This traditional method of raising local chickens not only ensures high-quality products but also promotes sustainable farming practices that are environmentally friendly and beneficial to both farmers and consumers.
Manual Video Measuring Machine
Manual vision measuring machine is a precision measurement instrument that uses manual driving for 3 axes, and the measurement software is manual point taking.
This instrument uses a zoom objective to magnify the measured object, and the image is input into a computer through a CCD industrial camera device. The enlarged image of the measured object is transmitted to the measurement software for non-contact and efficient geometric measurement of various complex workpieces.
Suitable for non-contact measurement of stamped parts, plastic parts, thin film shaped, easily deformed, easily damaged, and small-sized workpieces, such as workpiece measurement in industries such as rubber, plastic, small hardware, clocks, and light industry.Video Device
.
The vision measuring machine consists of three parts: an image acquisition device, a data acquisition device, and a two-dimensional measurement software. The zoom objective lens and high-resolution color camera form an image acquisition device, and the data acquisition device is composed of a grating ruler and a data processor. The image and data are measured using 2D measurement software to achieve point, line, arc, and distance measurements.
