Beef slaughter the best time

The growth and development of beef cattle showed that the growth of livestock before the age of 1 was faster, and the growth rate gradually decreased after 1 year old, especially after 1.6 to 2.0 years old. Taking Charolais cows as an example, daily gains range from 1.18 to 1.50kg for newborns to 6 months of age, and 1.05 to 0.90kg for 7-12 months. Tests have shown that younger beef cattle require 1 kg less weight than older cattle. Therefore, from the perspective of total feed consumption, capital turnover, and equipment utilization, it is advantageous to keep young cattle younger than older cattle. At present, in the vast agricultural and pastoral areas of China, weaning cows are weaned from 4 to 6 months of age, grazing is the mainstay in summer and autumn, and feeding is appropriate. Winter and spring are used for feeding in plastic greenhouses. Generally in the late autumn and winter of the second year, the yak is suitable for slaughter when the yak is 1.5 years old after birth and weighs about 300kg. At this time, the cow has a faster weight gain, tender meat, less feed for fattening, and low feeding costs, and is suitable for promotion in a large number of agricultural and pastoral areas. At the same time, the slaughterhouse cattle are slaughtered after 3 to 4 months of strength and fattened when the 2.0-year-old body weight reaches 500 kg, which is beneficial to the cattle farmers and the consumers.

Dome Fixed Focus Camera

The Dome Fixed Focus Camera/ Dome Fixed Focus Camera Indoor/ Dome Fixed Focus Webcam/ Fixed Focus Dome Webcam Night Vision/ IR Fixed Focus dome camera/ Fixed Focus Dome Camera 360°belongs to both the Fixed Focus Camera and the Dome Camera. So what is the Dome Camera?

The Dome Camera, as the name implies, has the dome shape, and this dome shape is exactly the origin of this name "Dome camera". The Dome Camera is very suitable to be used in the office places and places with the high-grade decoration because of its small size and beautiful appearance. The Dome Camera is composed of a camera, an automatic iris manual zoom lens, a dome cover with the excellent sealing performance, and a precise camera mounting bracket; and its biggest feature is its exquisite design, beautiful appearance and easy installation.

With the security surveillance cameras applied extensively and deeply, in the pursuit of the convenient installation and debugging, and the full coordination with the the building environment(both beautiful and concealed), the Dome Camera is developed. Now the Dome Camera has been widely used in the TV surveillance projects.

Although the Dome Camera's composition has many similarities with the Bullet Camera, for example, both are fixed cameras, the Dome Camera has the delicate protective cover and mounting bracket, while the Bullet Camera needs to be equipped with a protective cover. The Dome Camera has a zoom lens with the small zoom range and the lens is not easy to replace; while the zoom range of the Bullet Camera depends on the selected lens, from several times to several times, and the lens replacement is very convenient. Dome cameras are mostly used in indoor small-scale monitoring occasions, such as the entrances and exits, passages, elevator cars, etc. of important parts; while the scope of Bullet Camera's application is very wide, according to the selection of different lenses, long-distance or wide-angle monitoring can be realized, and the application occasions are much wider than that of the Dome Camera.

With surveillance applications wider and wider; due to the convenience of installation and debugging, and the concealment of the surveillance, the dome camera has been widely applied to the indoor surveillance, such as the places with the ceiling and the rarely changing light. The Dome Camera technology also changes very quickly. For example, firstly, the camera shooting function of the Dome Camera is not different from the high-performance Bullet Camera, and the Dome Camera is miniaturized; Secondly, the lens of the Dome Camera is also automatic iris + manual zoom, and the zoom range gradually increases; Thirdly, the overall sealing performance of the Dome Camera is better, especially the lower dome, it is made thin and uniform, with better light transmittance and less light loss; Last but not the least, the mechanical design of the mounting bracket is more exquisite, which makes the adjustment of the camera position very convenient, and the three-dimensional adjustable universal joint bracket has appeared.

In conclusion, compared with the Bullet Camera, the Dome Fixed Focus Camera also has many advantages, and we should choose the suitable type according to our appliying occassions.
