Shandong Qingfeng | Calf high survival rate, should follow the rules
Release time:
2021-06-28
Calves are born in time to eat enough colostrum. It is best to ensure that calves are taken for 6-12 hours after birth. The beneficial bacteria quickly occupy the space, sterilize with bacteria, inhibit bacteria, effectively regulate intestinal health, prevent calf diarrhea, and effectively improve the survival rate and the incidence of pneumonia.
How can the job of raising these reserve herds be done well? In fact, this job does not require a lot of money and expensive equipment. Whether you have 50 calves or 5000 calves, follow these basic rules:
Like humans, calves are babies, and they need a lot of "meticulous care and love." When treating calves, be sure to be light. No matter what kind of calf house they live in, ensure that their living environment is always dry and well ventilated, but avoid culprits. Make sure the feeding equipment is clean and sterile, because these babies have immune systems that are not perfect enough to resist disease. Try to arrange the time of stress events, such as ear marking, horn removal, marking, castration or vaccination, etc. Don't do these things near weaning, and be sure to handle these tasks humanely.
For any calf, colostrum is an important factor in their survival. Colostrum can provide very powerful antibodies, and only it can provide. At the same time, the time for calves to get colostrum help is very short, once the calves are born 12 hours, the intestinal receptors are unlikely to absorb a large amount of colostrum nutrients to fight the disease. The study recommends that calves should be fed 4.5 liters of colostrum within the first 6 hours of life, and if possible, at least half of the amount should be fed within the first hour. If the calf is not ready to drink a large amount of colostrum from the bottle, a colostrum feeder is required. When dealing with colostrum, we must pay attention to the details and ensure environmental hygiene. Do not leave warm colostrum unrefrigerated, either feed the calves immediately or refrigerate them immediately. You can use a colostrum meter to measure the level of immunoglobulin. When feeding calves colostrum for the first or two times, make sure that colostrum is not contaminated "green food". Raising cattle: Why can't you just eat fat and have poor fattening effect! Reducing the ratio of feed to meat is the key! Finally, if you are working to eradicate paratuberculosis in your herd, throw away the colostrum of cows that are paratuberculosis positive, or feed them with high-quality milk replacer.
1: Solve the problem of maternal reproduction (for example, long interbirth time, repeated mating infertility, frequent abortion)
2: extend the peak period of lactation; improve milk production.
3: Extend the life of the mother; (an 8,000-litre cow loses 60kg of minerals in its milk)
4: Improve the comprehensive health index of dairy cows and reduce the incidence of dairy cows (e. g. mastitis, hoof disease).
5: Cow pica disappears (gnawing wood, licking hair, licking urine, gnawing plastic) and the fur is smooth.
6: to promote food digestion, improve feed utilization, saving concentrate.
It depends on the location of the cattle farm, and in some places the climate may actually be suitable for calves for only a handful of months of the year. The ideal temperature for calves to grow outdoors is 20 degrees Celsius. If the temperature is too high, they will produce heat stress. Timely provision of fresh and sufficient clean drinking water and shade pergola is important to help calves relieve heat stress. For calves of 0 to 3 weeks old, cold stress will occur when the temperature is lower than 15.6 degrees Celsius; for calves of 3 weeks or more, cold stress will occur when the ambient temperature is lower than 5.6 degrees Celsius. In cold climates, calves will consume the fat accumulated in their bodies to maintain their body temperature as much as possible without additional nutrition. If the body consumes too much fat, calves are likely to get sick because their immune system is declining. Calves don't need a lot of extra fat, but if they consume too much fat in their bodies, they will starve to death very quickly, but just to try to stay warm. A very good lesson: when the temperature drops to minus 18 degrees Celsius, calves will need to be fed twice the amount of solid milk replacer or waste milk. Between minus 18 degrees Celsius and 16 degrees Celsius, the feeding amount of milk should be adjusted accordingly, and a nutritionist or veterinarian will assist you in determining the feeding amount. A large amount of thick, dry bedding can help calves snuggle comfortably together, maintain their body heat, or make small waistcoats for calves. In the summer, minimize the number of flies and keep the barn dry. If necessary, use pesticides.
Unfortunately, today there is no very clear guideline for the most appropriate rearing of calves. However, many experts agree that feeding 2.3 liters of 20% protein and 20% milk fat twice a day does not provide enough nutrition for the rapid growth of most calves. If you use milk replacer, you should consider feeding milk replacer with higher nutritional level (protein 28%, fat 20%), so as to be closer to the nutritional content of milk. Studies have shown that feeding more high-protein milk replacer allows calves to gain weight faster, grow taller, and avoid slow feeding, health decline and slow weight gain after weaning. Remember: these types of milk replacers are more expensive, but in fact, the cost per kilogram of weight gain for calves is lower. If you pasteurize waste milk, process monitoring is very important and is the primary consideration. In fact, incorrect pasteurization methods will increase the number of bacteria instead of decreasing. As a result, although there is a lot of investment in the pasteurization machine, there are problems with the health of calves. The nutritional level of pasteurized waste milk was detected regularly, and the milk nutrition balancing agent was added to ensure the stability and balance of nutritional intake of calves.
Just like the garden, your calf "vegetation" also needs to be fed and drank on time. Try to keep the feeding time consistent every day and ensure that each calf has a clean and dry feeder for feeding and drinking water. The starter is made up of a variety of different nutrients, including additives such as vitamin B and coccostosis. The choice of starter should be based on the calf's feed intake and the effect of weight gain. When the calf is about 3 days old, she starts to feed her some dry feed. Feed a little at the beginning and clean the remaining feed from the feeder every day so that the calves always enjoy fresh, clean feed. Water is also an essential nutrient, especially when feeding milk replacer with high protein content. In winter, the supply of drinking water can be tricky, but you should do your best to get calves to drink fresh and clean water at any time, starting from about 3 days of age.
Do you cut a larger mouth in the nipple of the bottle that feeds the calf? This may seem reasonable, but when you do, you actually put the calf at risk of bloating, ulcers and aspiration pneumonia. Raising cattle: why do you not grow fat by eating alone and the fattening effect is poor! Reducing the ratio of feed to meat is the key! Calves that drink milk too quickly are prone to aspiration pneumonia, as some of the fluid will choke into the lungs rather than into the digestive tract. If the use of milk bucket feeding, the same problem will arise. If you have calves with this problem, you can put a rubber duckling in the milk bucket to slow the calf down. It sounds funny, but it does work.
Calves are born in time to eat enough colostrum. It is best to ensure that calves take Laifuxing 6-12 hours after birth. The beneficial bacteria quickly occupy the space, sterilize with bacteria, inhibit bacteria, effectively regulate intestinal health, prevent calf diarrhea, and effectively improve the survival rate and the incidence of pneumonia.
You 've probably heard a lot of arguments about this, but industry experts are in favor of feeding milk or milk replacer to calves with diarrhea. When calves are sick, they need more nutrition, not less. If they suffer from cold stress and are already malnourished, "taking away" their milk can be a disaster. Consult with your veterinarian to develop a plan to use another method of treating calf diarrhea, which may include fluids, electrolytes, or antibiotics, but calves should still be fed milk replacer or milk as normal.
"Biosecurity" is no longer just a technical term for large pastures. Everyone can and should take measures to prevent the spread of diseases between animals, and you can certainly do it! Marking the colostrum of cows suffering from paratuberculosis, pasteurizing waste milk, and avoiding nose contact between calves-these three points are the biosafety management measures we have already mentioned. Other aspects include daily care for sick calves, wearing rubber gloves, washing hands frequently when working with calves, and thoroughly disinfecting equipment after each feeding. If you use a bucket to feed water or milk your calves, make sure each calf has an exclusive bucket. Even after weaning, try not to mix the month-old calves and month-old calves. If you buy calves from other cattle farms or sales outlets, be sure to keep the calves in isolation for 3 weeks.
There are many drugs on the market for the treatment of calf diseases, and some of them provide quite convincing evidence of their efficacy. Working with healthy calves is happier, not to mention less expensive and less time-consuming. Do your best, unswervingly insist on all the fine links of calf feeding in place, and prevent calves from suffering from diseases in the first time. Ensure that each calf is clearly authenticated and establish a system to record the growth of calves, which can help you track signs of disease, weight gain, body height and management in time. These records can also help you and your advisor make decisions, and hopefully reduce the number of sick calves to a minimum. Be sure to take the time to raise calves patiently, because they are the future of the cattle farm!
