Lafuxing was produced in 1980 and has been certified by the Food and Agriculture Organization of the United Nations/World Health Organization. It is archived in the Royal Pharmaceutical Society and listed in the National Collection Office. Shandong Qingfeng and the United States ADM reached a strategic partnership. ARCHER DANELS MIDLAND COMPANY,ADM was established in 1902 and is known as one of the world's top 500 enterprises and a global agricultural giant. It serves more than 170 countries, 500 agricultural product fruit harvest bases, 270 raw material factories, 44 research and development centers, and ADM's animal health and nutrition department ranks first in the world in terms of scale.
Although the cow is a ruminant, but strictly speaking, the newborn calf is not a ruminant. Because at birth, calves rely on milk or other liquid feed from their mothers, and their rumen is still in the growth stage, so newly born calves do not ruminate. It is known that the rumen volume of calves will increase by 1300 in the first 8 weeks after birth.
Studies have shown that after weaning calves into the diet feeding mode, the rumen pH value will decline. The decrease of rumen pH value will lead to the decrease of feed intake of cattle, which will affect the growth rate. At the same time, the low rumen pH value may also reduce the intestinal osmotic pressure and increase the risk of disease in young animals. Therefore, the calf weaning technology is also need to be carefully studied.
Calves feeding too early or too late is detrimental to their growth and health. What is the best time to wean a calf and start feeding forage?
Practice has proved that it is most suitable for calves to start feeding forage at the age of 3 weeks.
Calves within 3 weeks of age, the forestomach (rumen, reticulum, flap stomach) are very small, do not have the ability to digest forage, there are no microorganisms and ciliates, can only rely on eating milk into the true stomach for absorption and utilization. Feeding forage at this time will increase the burden on the calf's forestomach and cause disease. If the forage is fed too late, the stomach and intestines cannot get exercise, the forestomach grows slowly, and the volume is too small, which will also affect the growth and health.
After 3 weeks of calves, the former stomach increases rapidly, and due to contact with a small amount of food and water, microorganisms enter the former stomach with the mouth, at this time, the calves begin to ruminate. At this time, fresh and tender grass, wild vegetables, high-quality dry grass, crushed concentrate, etc. are fed, and the feeding amount and the amount of roughage are increased with the growth of weeks, which can not only avoid causing diseases, but also accelerate the development of forestomach, promote the reproduction of microorganisms and ciliates in the rumen, gradually strengthen its function of digesting forage and feed, and feed a large amount of roughage for cattle in the future, grow up and gain more weight to lay a good foundation.
When are calves weaned?
1. There are two normal methods of weaning calves:
One is weaned at 110 days and weighs 170kg at the age of 6 months. The other is weaned at 60 days and weighs 160-165kg at the age of 6 months. In order to early weaned calves for strength fattening, give full play to its advantages, in order to achieve the desired goal in a relatively short period of time. At present, there is an early weaning method, weaning about 46 days. The method is as follows:
(1) 1-3 days after birth, eat enough colostrum and feed it three times a day;
(2) on the 4th to 7th days, milk 3 ㎏ is often fed 4 times a day;
(3)) On the 8th to 15th day, milk is regularly fed 3 to 4 ㎏ every day, and it is fed 4 times. Starting from the 10th day, high-quality digestible calf essence supplement and hay or calf TMR diet is supplemented, and a little less is added every day to keep freshness and train feeding;
(4) On the 16th to 28th days, milk is regularly fed 3 to 4 ㎏ every day, fed 3 times, and 0.5kg of daily ration is supplemented at the same time;
(5) On the 29th to 41st days, milk is regularly fed 2 to 3 ㎏ every day, fed twice, and 0.7kg of daily ration is supplemented at the same time;
(6) on the 42nd ~ 45th day, milk 2 ㎏ every day, feed once, and supplement 0.8kg of daily ration;
(7) On the 46th day, wean and supplement more than 1kg of diet;
2. Precautions during weaning:
① Calves cannot eat enough colostrum by themselves. They must be fed artificially. They must be fed early in sufficient quantity. If they exceed 12 hours, they will lose their effect.
② free feed clean, warm water, can not cut off the water.
③ The upper limit of feeding amount is taken in winter and the lower limit is taken in summer.
④ Weaning should be combined with time and feed intake. Weaning can be done after birth for more than 40 days and feeding 0.8kg for three consecutive days. Weaning and feeding cannot be carried out at the same time to avoid excessive stress.
effectively improve the survival rate
Prevention of diarrhea

Cattle and sheep are rumen animals, so cattle and sheep breeding should pay attention to the rumen health of cattle and sheep, intestinal health and so on. How to maintain the micro-ecological balance between the normal microorganisms in the rumen and the host, so that animals can make full use of feed, improve the body's resistance, and maintain the body's health? This is exactly the problem that our company has launched the "British Imported Lifestart Probiotics" dedicated to ruminants. Probiotic supplements are rich in beneficial microorganisms, provide highly absorbable energy to supplement colostrum and vitamins, can effectively prevent and treat intestinal diseases, can effectively adjust the balance of intestinal flora, and maintain normal intestinal microflora. Inhibit the reproduction of harmful intestinal bacteria, promote the growth of beneficial bacteria, and control the occurrence of intestinal diseases. There are many kinds of normal microorganisms in the rumen of cattle and sheep, mainly bacteria and ciliates, but in terms of the number of bacteria and the importance of metabolic activities, they are far more than ciliates. They play an important role in the nutritional metabolism of ruminants, affecting their digestion, absorption and metabolism, participating in the decomposition of feed and the synthesis of important organic compounds. Therefore, intestinal diseases and growth of ruminants are hindered, many are related to the imbalance of flora in the body. British imports of Fuxing Lifestart probiotics can be a good supplement in the rumen of cattle and sheep needed beneficial living bacteria, regulate intestinal health. Mainly summarize the following points:
Improving animal performance
Faster growth rate
Improve feed conversion rate
Improve gut health
Reduce morbidity
improve immunity
Reduce the number of salmonella
Antibiotic Growth Promoter Alternatives
Combined with antibiotics in some cases
1. Probiotics rapidly occupy the space for reproduction
2, increase feed intake, improve feed conversion rate, increase weight.
3, prevent diarrhea, improve the survival rate
4, activate their own immunity, improve immunity
