For each small cow, about 350kg-450kg of fresh milk is consumed in 60-90d, which accounts for about 10% of the total milk production in a lactation cycle.
Over the years, large enterprises such as Yili, Mengniu and Huaxi Hope have vigorously developed the dairy industry. Today's market demand is at a low level of saturation, which is also in line with the national conditions of China's primary stage of socialism.
That is to say, it is not that the milk produced by the cows is enough for people to drink, but because of the limitation of living standards, many people do not develop the habit of eating milk, or want to eat but can not eat for a long time.
Fresh milk is getting more expensive now, and colostrum is more expensive. The 400kg milk volume will greatly increase the cultivation cost of small cows. Many farmers choose to forcibly wean them after about 2 weeks of breastfeeding. What does the small cow after weaning eat?
It turns out that small cows can eat colostrum and regular milk in the first week of birth. In the second week, they enter the transition period of milk replacer. The ratio of milk replacer to milk in transition is gradually changed from 1:3 to 3:1. After the second week, the small cows can only eat the formula.
This technology has been popularized in developed dairy areas in foreign countries, and China has only started in the 1960s.
The role of the formula is equivalent to infant milk powder, containing protein, fat, lactose that is easily digested by young animals, and strengthens various vitamins, trace elements, amino acids and other active substances.
Once, protein levels and sources have profound effects on weaned dairy cows. Suitable protein levels can promote the growth and development of small cows, improve the digestion and utilization of nutrients by small cows, increase the digestibility of amino acids, and promote the calcium and phosphorus of animals. Digestion and absorption.
The current research results show that today's two major sources of protein: whole milk protein and substitute protein (soy protein extract, soy protein isolate, animal plasma protein, denatured wheat gluten, etc.), after optimization of the formula, for the growth of small cows The impact is almost indistinguishable.
Nowadays, the formula has become closer to the breast milk in terms of nutrients, immune components and taste. The small cows can effectively control diarrhea, enhance immunity, increase the adaptability and weight of small cows, promote growth and development, and cultivate high yield. The cow lays the foundation.
PTZ: In the security monitoring application, it is the abbreviation of Pan/Tilt/Zoom, representing the pan tilt omnidirectional (up and down, left and right) movement, lens zoom and zoom control.
Fuvision's autonomous automatic PTZ intelligent tracking enables the camera to automatically PTZ drive its own PTZ and zoom lens, and automatically controls the PTZ Camera to rotate the PTZ in all directions and zoom the lens. It also conducts visual oriented automatic tracking for the locked moving target to ensure that the tracking target continues to appear in the center of the lens with a close-up image, so that the guards can see the information more clearly, It can also be used for obtaining evidence afterwards. The automatic PTZ tracking module makes up for the narrow field of vision of fixed camera monitoring, which is an essential function of a perfect security monitoring system.
The intelligent vision PTZ automatic tracking and monitoring system has the target analysis function, and is equipped with a high-resolution camera, a large magnification optical zoom lens and a high speed PTZ, which can automatically capture suspicious targets quickly and accurately. By setting the preset position intelligent vision PTZ automatic tracking monitoring system, the preset position scanning, automatic cruise and other functions can be realized, and many special requirements of intelligent monitoring can also be realized. In addition, the intelligent vision PTZ automatic tracking and monitoring system also has the advantages of beautiful appearance and strong concealment, so it is very suitable for public security intelligent monitoring applications in airports, squares, rail transit, villas, government administrative units, military regions, museums and other types of places.
