Beef cow barn type

1, beef cattle house

The beef cattle house is a double-row cowshed. The length of the barn can be determined according to the number of cattle or location conditions. It is fence-style, with a walkway in the middle, feeding troughs and drinking fountains on both sides of the walkway, and cattle standing on their heads to feed. The barn can be one floor or two floors. The upper layer is stacked with forage grass, and the straw hole is set. The forage grass can be directly put into the feeding trough. This type of cow house has good insulation and cold resistance, and it is more suitable to feed fattening cattle in northern areas. Cows are required to make cattle beds, and calves must be equipped with stalls.

2, cowshed

This is a warm-hearted area in the south, a fenced-in cowshed built with fences and cowsheds. The internal structure is the same or similar to the cowshed. However, the cost is low and economical.

3, beef shed

This kind of cattle shed has a simple structure, so it has low cost and good ventilation. There is an open-air playground on the side of the cowshed and beef cattle sheds are suitable for the southern regions where winter is not too cold. The area of ​​the cattle shed should enable all cattle to stand and lie on a rainy day. One side of the shed is equipped with a feeding trough and a dieter. The other side is equipped with straw frame.

4, winter warm shed cowshed

This is a form in which the plastic film insulation is used in conjunction with the cowshed in northern areas. Plastic film covers 2/3 of the cowshed area. The plastic film used was a white transparent plastic film with no water droplets and the thickness was 0.02-0.05 mm. The slope of the plastic film canopy is between 40° and 60°. According to the actual situation, the terrain, area, etc. determine the slope. Covering time from November to March of the next year, according to local climate conditions in due course.

The plastic film in the greenhouse must be stretched and stretched, and it should not be ventilated. In the cold weather in the north, it must be covered with straw to ensure its insulation. During the day, air intakes and exhausts located on the south wall are used to ventilate air for 1 to 2 times to remove moisture and toxic gases from the booth. The density of rearing cows in a greenhouse shed is appropriate for every 4 square meters.

5, rural warehouses cowshed

Unused warehouses or other unused houses in rural areas can be used as cowhouses for beef cattle breeding. However, because this type of house was not constructed according to the requirements of the cowshed, it cannot be simply used as a barn and must be modified. According to the requirements of the local winter cold, summer ventilation and summer heat, first renovate and install doors and windows. Then make the ground non-slip, impervious cement or triple land surface. Build facilities such as feedlots and passageways so that feeding and management measures can be carried out normally.

6, solar cowshed

This is based on a double-slope barn on the roof in the north and is closed with a double plastic film on the sunny side slope. At the same time, the exterior wall of the sun was painted black, and then a diagonal wood frame was used and closed with a double plastic film. This formed a triangular solar energy receiving room outside the sunny wall, through which symmetrical vent holes were opened at equal distances on the wall. The cowshed communicates so that the triangle receives hot air heated by solar energy and flows into the cowshed continuously through the upper air vents to provide insulation.

Single Packed Mottled Waxy Corn

Waxy corn comes in a variety of colours. Some people wonder if waxy corn is a genetically modified product. In fact, it is not. Waxy corn originated in China. It is caused by a genetic mutation. Artificial selection gradually led to the emergence of a type of tannin.

Waxy corn, also known as waxy corn, is sticky corn. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dented corn. Its chemical and physical characteristics are controlled by a recessive gene (wx), which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.

Coloured glutinous corn is generally white, yellow, red, purple and black, with white, yellow and purple corn being the basic colours. Purple and white hybrids naturally become purple if the purple gene "beats" the white gene and vice versa, so if the two tie we see white and purple corn. Purple can turn into red and black corn, or as we often say, "red is purple and black is purple". Of these colourful corn, the most common yellow waxy corn is the most nutritious as it is rich in carotenoids...

Currently, the only genetically modified foods sold on the Chinese market are soybean oil and papaya. Waxy maize is a hybrid variety and is not associated with genetic modification. Therefore, it can be concluded that glutinous maize is a hybrid variety and has nothing to do with genetic modification.

Genetic modification is a type of "genetic engineering" in modern science and technology, which makes use of modern molecular biology techniques. Hybridisation is the mating of individuals of different genotypes to produce offspring that are different from the original "pure" breed. In a sense, it belongs to the natural exchange of genes that can occur in nature.
