what to feed calves after weaning

We use cookies to provide you with a better experience. WebIn addition, the risk of enteric disease after weaning is less than during the liquid feeding period, making early weaning beneficial in the management of enteric disease. Also, consult your veterinarian as to herd health strategies. Research has shown that nutrient digestibility post-weaning is reduced when calves drink larger amounts of milk and consume little dry feed prior to Making sure a heifer is fully prepared before weaning Store your calves grain in a place where you can prevent rodent problems. This affects the age of first freshening and lactation milk production. Calves should be acclimated to the pasture or facility that they will encounter during and after weaning. Research examining advantages and disadvantages of one-step vs. two-step weaning methods is sparse and results have been variable. The weaning process should happen gradually, over a few weeks. Calves can be maintained on the starter for 2 to 3 weeks postweaning and then transition to a grower diet offered with long forage. Concentrates should be offered two to three times daily as the calf grows and develops to ensure proper rumen development. This dramatically decreases animal performance and animal health. Temperatures over 85 F will increase breath rate, cause sweating and raise body temperature. Calves can die from being chilled even at temperatures above freezing. Thus, you should have a routine plan for washing and sanitizing utensils during calf chores. Optimal relative humidity for calf housing is around 65 to 75 percent. It marks the point where the calf is separated from its mother and must learn to rely on its own resources to survive. Insufficient growth rates result in either an older age at first calving, which increases the cost of heifer rearing, or smaller dams at first calving, which limits milk production and conception rates during the first lactation. Dont use a dairy chlorine sanitizer. When animals become stressed, they are more likely to get sick. Use of corn silage without restricting energy intake will result in greater fat accumulation but not optimal frame growth. After cattle have reached approximately 1.5% of body weight in feed intake (dry matter basis), increase the amount of feed offered every other day. Preparation is an important component of a successful, low-stress weaning program. The table below illustrates how you can achieve feeding calves 750 g per day. Two-step weaning methods require a bit more planning and management as compared with traditional weaning because calves will need to be handled at least twice and producers need to ensure they have adequate facilities to support the process. Properly managing newborn calves can reduce disease risk. After third week, the crude protein level can be reduced to 12.5% to 13%, since the cattle should be on full feed by then. Copyright 2023 Merck & Co., Inc., Rahway, NJ, USA and its affiliates. Heifer target growth curves are available by breed. The most likely scenarios are a cow has died, a cow isnt giving enough milk, or a twin has been rejected. Producers should strive to reduce the stress associated with weaning as much as possible to promote optimal They are also easy to clean. Conversely, excessive growth rates, especially those associated primarily with fattening, can adversely affect subsequent milk production and also increase the risk of metabolic problems at calving. Privacy Notice Not only is this ideal in terms of animal welfare, but good performance of calves after sale reflects positively on the cow-calf producer. In this feeding system, targeted mean daily gain for calves of large dairy breeds is between 400 and 600 g/day for the first 34 weeks of life. doi: 10.1892/0891-6640(2000)014<0569:ptocii>2.3.co;2. If fenceline weaning is the method of choice, ensure that the shared fenceline is adequate to keep calves and cows separated. If their illness was severe enough or long term, permanent damage or chronic pain may result in these animals becoming economic risks. All rights reserved. We have successfully started calves on Use a chlorinated alkaline detergent. Cold air carries and removes less moisture than warm air. Some folks used a commercial ration for the first two to three weeks after weaning and then switched to a complete mix thereafter because it was more economical. Everything the calf comes in contact with should be clean and dry, especially the bottles and buckets. However, it is very important that the calf can continue on a high growth pattern and not diminish those gains after weaning so that the resources used in high milk feeding are not wasted. The different dietary requirements of calves at different ages dictate that they be kept in separate pens based on their age and size. Mississippi State University Extension. The no-vaccine window. SMS Terms & Conditions Keep ventilation inlets and windows screened at all times to control flies. Walk-in grain rooms tend to be feeding spots for rodents. Provide clean water and grass-legume hay directly off the truck and allow cattle a rest period before processing them. Make modifications based on amountof manure and bedding. Abrupt changes in feed can disrupt rumen function, which can lead to digestive problems. One-step weaning, or traditional weaning, involves abrupt separation of cows from calves. Feeding Calves Shortly After Weaning: After weaning, changes in the grain mix and group housing should be made one at a time, and changes should be made gradually over a two-week period. Fenceline weaning is accomplished by separating calves from their dams by a single fence about a week before complete separation. Humidity can cause calves to become damp and sick. Milk, feed and water buckets are breeding grounds for pathogens, disease-causing organisms. Scrape the ground to a fresh level of dirt and remove all leftover organic material. This temperature promotes maximum Mating Capacity of Bulls; Bull to Cow Ratio, A few fines or clumps of feed in the bunk. 600 lb calf gets 6 lbs of grain per day. Managing heifer calves can help you make sure they: Theres no single best way to raise calves. When complete separation is desired, cows, not calves, should be moved to a different field/facility. One of our nutrition experts may be able to help. The legacy of this great resource continues as the Merck Veterinary Manual in the US and Canada and the MSD Vet Manual outside of North America. Feeding hay during the receiving period reduces the energy density of the diet. Hang them up. As a result growth rate declines. Groups of 6 to 12 are ok when calves reach about 4 months of age. Mix the milk replacer with warm water and try to keep the milk replacer temperature consistent between feedings (Parish, 2019). In general, the feeding of corn silage during this period should be limited to no more than one-half of the diet dry matter, preferably less. Fermentation products of Saccharomyces cerevisiae have been shown to positively influence ruminal microbiota and improve ruminal Consider water sources, cleanliness. During the preweaning period, make sure the calves diet (liquid feed, forage, and grain) are all high quality. Jim Salfer, Extension educator, and Neil Broadwater. It isimportant to have the correct size and shape of brushes to clean bottles and especially esophageal tubes. WebCalves usually prefer a dry grain mix at first, but will quickly adapt to high moisture feeds, including corn silage over a 1-2 week period. Make sure you offer water at least twice daily. The one-step, traditional weaning method is the simplest and least management intensive option. Rinse containers with lukewarm water before washing. Calves that have used feeding bunks and water troughs before weaning may go on feed faster after weaning. Shipment, intermingling with new animals, and introduction to new facilities are major stressors that can negatively impact calf performance. This concentrate feed is what allows rapid gains (not hay), but the cattle must be adjusted to the diet slowly. Bunk space is another essential factor that contributes to a calfs growth and development. Take apart pens and hutches and move to a clean area. About 40 days of age may be a practical minimum for early weaning in beef herds. Precision feeding entails limited intake to meet requirements. How do I submit an idea for an article? If the uneaten feed looks pretty similar to the original mix (no sorting), it can be re-mixed with new concentrate mix so that there is little feed wasted, but be sure that you consider the pounds of uneaten feed that you are re-feeding, and dont give them that plus the normal amount of new feed, or they will be fed too much. If you have calves with scours, use 1.5 cups to 5 gallons. Evaluate bunk space, management. In contrast, two-step weaning involves gradual separation of cows and calves either via a fenceline or the use of nose-flaps. Compared to the last survey on the 2014 calf crop, the use of fence-line weaning has increased by over 10%, and the number of producers using two-stage weaning has Use a rectal thermometer regularly to help detect early fever in sick calves. #5. Plus, it can pay off handsomely in terms of helping to get cattle to eat and restoring optimal rumen function, especially in calves that are timid at the bunk. Spam protection has stopped this request. If they do not eat the mix, weigh back the uneaten feed. Clark County, KY. Mar 20, 2021.

WebIn the dry-lot feeding after weaning, the steers were fed in bunks within a shed open to the south. As calves consume more concentrate, back off the amount of hay fed to 1.5 to 2.0 pounds per day. During the first two to three weeks, calves make a transition to a new plane of nutrition. Therefore, the level of feed intake should determine the percent protein fed. Research shows that these conditions allow bacteria to reproduce at least once an hour and often twice in the same time. Soybean meal may be the protein source of choice due to cost and availability, but using a source of higher rumen bypass protein such as distillers grain in combination with soybean meal is good. Institute of Agriculture and Natural Resources, University of Nebraska - Lincoln. Additionally, providing calves with long-stemmed forage can help increase saliva intake, which can help to buffer the rumen allowing the rumen microbes to function more efficiently. Place a plywood cover over the rear part of the pen to reduce drafts and to keep in the calfs heat. Another source of stress during weaning is the change in diet that calves experience. Also, consult your veterinarian as to herd health strategies. production). Hot water makes the milk proteins stick to the surfaces. Hutches should allow steady air flow without draft. WebTwo weeks after weaning, calves should eat about 2.5 percent of their body weight on a dry matter basis. Proper management can greatly reduce the illness and death rates of calves. Consider adding molasses, silage or other wet feeds to the diet to decrease the sorting of mineral and vitamin supplements. There are many types of bedding including: Of the bedding types, straw promotes the highest fly populations. Grain should be provided up to a dry-matter intake of 2.53 kg/day; thereafter, additional high-quality forage should be provided. 2. Following these steps and using the correct soaps and acid will emulsify the fats and break down the carbohydrates and proteins. More typical prebreeding heifer diets would contain at least 15% crude protein, and up to 18%. They also can get dirty and harbor pathogenic bacteria. WebStress at weaning affects a calfs immune system for at least two weeks after weaning. Dairy replacement growth rates ultimately affect the timing of puberty. Follow the 10% rule. Once the calves are on feed, I would expect little or no refused feed. Two major drawbacks to the use of nose-flap weaning are 1) the cost of the nose-flaps themselves; and 2) the amount of time it takes the calf to adapt to eating or grazing after the nose-flap is installed, which can have implications for growth. This can make calves more susceptible to disease, particularly pneumonia, and can reduce growth rates. WebAt the time of weaning, calves usually are consuming between 8 to 16 quarts/day of milk or reconstituted milk replacer, depending on how the feeder was programmed and the goals of the operation. von Keyserlingk, M. A. G., Rushen, J., de Passill, A. M., & Weary, D. M. (2009). Begin by separating the puppies from their mother for a few hours at a time. The doses of SB supplementation were based on the study of Slusarczyk et al. Combining these events with the added stress of weaning is a recipe for disaster and can increase risk for illness and major setbacks upon arrival to the feedyard or stocker. Never increase or decrease the amount of feed offered by more than 5-10%. WebFor the first two weeks, feed calves twice daily. Even if calves are sold after weaning, good post-weaning performance reflects well on the cow-calf producer and the industry as a whole. After weaning, calves must adjust to a new diet, which can consist of new feedstuffs to the calf. Provide 1.0 to 1.5 ft of bunk space per calf if possible. Many of the resources on bottle-calf management come from the dairy industry; however, beef producers can tailor dairy industry strategies to fit their own operation. High milk intakes before weaning can depress solid feed intakes after weaning if milk feeding is ended abruptly (Terr et al., 2007; Weary et al., 2008). Allow calves easy access to feed and water. If animals have no interest in coming to the bunk when they are fed, they are probably being overfed, or there is spoiled feed in their bunk.

Producers should strive to reduce the stress associated with weaning as much as possible to promote optimal performance post-weaning. All rights reserved. Proper ventilation moves air and provides fresh air to: Remove extra moisture in the winter and heat in the summer. Calves and cows are completely separated (no physical, visual, or auditory contact) on a specific date and managed accordingly thereafter. Decrease in the number of heifers for replacement, which limits culling ability or increases the need to buy replacements. When they are suddenly removed from this familiar environment, it can be a traumatic experience that leaves them feeling timid and anxious. Bottle-feeding a calf is a large time commitment for beef producers, and decreasing the length of bottle feeding may be beneficial. Weba Milk replacer fed twice, daily *First 3 to 4 days, feed colostrum Source: Table adapted from Kochewad, 2013. Colostrum can be obtained by milking the mother, using colostrum that has been previously acquired, or purchasing commercially available colostrum replacer (Walz, 2019). This change can be difficult for some calves, which can lead to reduced appetite, digestive issues and weight loss. Increased growth days results in higher heifer rearing costs prior to her first entry into the milking herd.
