Sep 04, 2017 · Newborn calves are sometimes too weak to suckle or nurse from a pail or bottle. The esophageal feeder is an excellent device for force-feeding colostrum to these calves or for feeding electrolytes to sick calves. This inexpensive piece of equipment can save the life of a sick or weak calf.Estimated Reading Time: 8 mins
calf hutches should be cleaned and moved to a new location to control the spread of potential diseases. Milk Feeding Options For the first two weeks of life, calves receive most of their nutrition from milk. From four days of age, calves can be fed either whole milk, waste milk, reconstituted milk replacer, or fermented or fresh colostrum (Table 3).

I am a fifth generation cattle producer on my family farm. Feeding Amount For many years, liquid feeding programs were designed to limit the amount of liquid feed and encourage early intake of dry feeds. Many pelleted starters contain lower levels of starch to minimize the risk of acidosis. The same problem with bacterial growth can occur after frozen colostrum is thawed. Colostrum affects both morbidity illness and mortality death. Volume is not the only factor determining the successful transfer of immunity from cow to calf. Click here to email an editor. Antibodies from colostrum protect calves until their own immune systems are fully functional. Pasteurization may provide an added benefit of higher serum total protein concentrations in calves. As the stomach develops more fully, the calf begins functioning as a mature ruminant. This amount is typically divided into two feedings of 6 pounds. Once the length of tube needed has been determined, it is time to begin inserting the tube. Storage and Handling Storage and handling influence colostrum quality. Bedding can, in some cases, supply this small amount of straw, so type and frequency of bedding may also influence the time at which calves need to be offered forage. You can feel or see the bulb end of the tube slip down the throat and into the esophagus. One pint of liquid milk or milk replacer weighs about 1 pound, so this would be 3 quarts at each feeding. The diet has long been known to affect this aspect of rumen development. The "clinical threshold dose" the level of exposure that results in disease is considerably lower for colostrum-deprived calves than for colostrum-fed calves Figure 6. In calves fed milk and grain papillae grow larger and the rumen walls thicken as calves get older. Effects of variation in nutrient intake were seen in these trials, even though the average or total nutrient intake was similar. Calves were weaned at 42 days. Energy Energy is used to support body functions and allow dietary protein to be used in building body tissue. It allows producers to wean calves from a very high energy intake without the risk of growth checks. High rates of milk or milk replacer feeding and high levels of fat in milk replacer depress starter intake. The rumen will be small relative to the abomasum if the calf receives a diet of only milk or milk replacer for 6 or more weeks. Open the calf's mouth by applying pressure to the corner of the mouth or by grabbing over the bridge of the nose and applying pressure to the upper palate or gums. The level of IgG necessary to provide adequate protection to the calf will vary depending on the pathogen load in colostrum and the environment, stress, housing, and feeding practices. It is important to remember that deciding to wean calves at a later age or bigger body weight does not remove the rumen development requirement. Did you make this project? It tells how much CMR or dry matter of whole milk the calf has absorbed until day A textured grain with coarsely processed corn, small grains, and pellets fortified with protein, minerals, and vitamins is recommended Table 9. Monitor the time and temperature of pasteurization and cleaning processes, and test bacteria levels before and after pasteurization periodically. With this in mind, farmers can adopt one of two different feeding strategies: The economy feeding curve or the metabolic feeding curve. Ease weaning stress by ensuring calves eat at least half a pound of grain per day for 4 weeks or a pound per day for 2 weeks and that they reach 2 pounds per day for 3 consecutive days before weaning. To use them successfully, grain buckets need to be emptied and refilled one or two times each day, especially during hot weather. By three weeks of age, there is a marked improvement in the calf's ability to digest carbohydrates, although the digestion of starch varies according to its origin and processing methods. It is ideal to keep enough frozen colostrum on hand to feed several calves. A wide range of growth can be achieved by selecting a feeding program that matches your goals for calf growth. The esophageal feeder is an excellent device for force-feeding colostrum to these calves or for feeding electrolytes to sick calves. Within two weeks of age, the calf can digest starch. When feeding is over, slowly remove the tube. Low enzyme activity and curd formation following first colostrum feeding allow the calf to digest and assimilate nutrients slowly, yet efficiently, preventing scours caused by undigested nutrients reaching the large intestine. It is important to not force the colostrum out of the container. If he fails to swallow, it may go into his windpipe instead. A scale that starts at zero and goes to approximately 35 provides a good range for testing colostrum. The objective of calf nutrition is to promote rumen development early in life. Hold the end of the tube with the plastic nub up to the calf just behind its front shoulder. However, feeding waste milk increases risks of pathogen exposure, antibiotic residues, and antibiotic resistance. However, calves should be introduced to the automatic feeder not later than in the third week, so the weaning process can slowly be introduced. The gap between passive immunity provided by colostrum and the calf's own immunity creates a period where the calf is at greater risk of illness Figure 4. In real world conditions, neither total nor average intake is controlled.
By Heather Smith Thomas — There are times you must get fluid into a newborn calf that needs colostrum or a sick calf that needs fluid and medications given orally. If a newborn calf is unable to nurse its mother or suck a bottle, the quickest and safest way to get colostrum into him is knowing how to tube feed a calf. A sick calf generally will not nurse a bottle, and the only way to give him adequate fluid is by tube. Years ago, before esophageal feeders were invented, the flexible nasogastric tube was the only way to get fluid into a calf. We also use a larger diameter nasogastric tube for administering fluid or mineral oil to adult cattle. For giving baby calves colostrum or electrolyte fluids, however, the esophageal feeder is extremely adequate and easy to use. Many ranchers today use this handy tool. When the calf is properly restrained and the probe carefully placed, it is a very effective and safe way to give fluid. Both the esophageal feeding probe and the nasogastric tube must be inserted carefully and properly, to decrease the risk of injuring or drowning the calf. A container for milk or fluid is attached to the other end. Some have a valve that keeps the fluid in the container from entering the tube until you release it. Others have a container bag that hangs down until you are ready to administer the fluid, and you raise it up when you want the fluid to go into the tube. The rounded bulb on the end of the probe protects the mouth and throat from being scraped or punctured and helps prevent backflow of fluids up the esophagus; acting as a plug. It also helps the tube bypass the larynx and small opening into the windpipe when you are inserting the tube into the throat. The windpipe is slightly below and alongside the opening into the esophagus. You must not get any fluid into the windpipe; if it gets down into the lungs it will drown the calf. If the calf is lying down, lift his head up to insert the tube. Gently put the tube into the side of his mouth. This is easier and easier on the calf than trying to force it into the front. Then aim it straight and slide it over the tongue to the back of the mouth and into the throat. The calf should swallow it as you move it back and forth and apply gentle pressure. Make sure the tube is not forced into the windpipe; the calf must be given a chance to swallow as it is pushed down. Stop pushing for an instant and place your fingers on the outside of the neck front of the throat , to determine where the tube is going. You can feel or see the bulb end of the tube slip down the throat and into the esophagus. For calves, a flexible plastic or nylon tube about 4 feet long is usually adequate. This type of tube is handy to administer fluids or liquid medications, and better than an esophageal feeder if you are treating a bloated animal; it goes clear into the rumen and can let gas come back out the tube before you pour in the mineral oil or other medications. It is also useful if a calf has been eating dirt and is plugged up. You can put a small amount of water directly into the stomach and then let it come back out the tube, bringing dirt with it. By alternately putting water in and draining it out, you can clean a lot of dirt out of a calf. You can make a nasogastric tube from any flexible tubing of the proper diameter. You can administer fluid by attaching a large funnel to your end of the tube after the smooth end has been put into the stomach via the nostril. Tuck his nose downward toward his chest before inserting the tube. If his head pointed up or stretched forward, the tube is more likely to go into the windpipe instead of the esophagus. If he clamps it shut, it will be difficult to insert the tube and may also bloody his nose. Push the tube quickly to the back of the throat and then go gently and slowly so the calf can swallow it. He must swallow it before it can enter the esophagus. If he fails to swallow, it may go into his windpipe instead. On rare occasion, it may even curve around and start back out through the other nostril. If this happens, gently pull it out and start over. Make sure the tube is swallowed and goes down the esophagus. Take it out and start over. If giving castor oil to a plugged or shut-down calf, shake up four to six ounces of oil with an equal amount of very warm water in a small jar and suck the mixture up into your syringe.

If a calf misses its second visit and only obtains one or two meals on the next feeding day, that means instead of the desired grams per day, it often only receives half the amount of CMR. This explains why older cows often produce colostrum with a greater number and variety of immunoglobulins than younger cows. Chymosin, also known as rennin, binds specifically with casein. The nitrogen in this excess protein ends up in manure, increasing the amount of nitrogen that must be removed from the farm. In most cases, differences in calf growth due to preweaning feeding rate disappear by the time calves reach 4 to 6 months of age. As with the economy curve, the metabolic feeding curve also integrates an early reduction of CMR concentration to prepare for the actual weaning of calves. Within 6 hours, the average ability of the gut walls to absorb immunoglobulins decreases by one-third. You must not get any fluid into the windpipe; if it gets down into the lungs it will drown the calf. Newborn calves need the first milk from their mother to prime their immune systems with antibodies and prepare them for the first few days of their life. Chill colostrum pre- and postpasteurization if it is not used immediately. In addition, when rumen microbes digest forages they produce acetate, which will not impact rumen development. Feeding Results E. Keep in mind that some bacteria may survive pasteurization; it is not sterilization. The objective of calf nutrition is to promote rumen development early in life. In addition, evaluate the long-term impact of higher rates of gain from an economic standpoint. If dry matter is not increased, the extra protein essentially is wasted because energy becomes the first limiting factor. You can put a small amount of water directly into the stomach and then let it come back out the tube, bringing dirt with it. Milk replacers in the United States are typically based on whey and whey protein concentrate. While these programs do not support maximal weight gains before weaning, they do promote rumen development and early weaning. Usually, the second milking contains 60 to 70 percent as many immunoglobulins as the first milking Table 2. The young calf also requires the fat-soluble vitamins A, D, and E, which are in short supply at birth, but which are present in colostrum. When the tube is over the back of the tongue, the calf starts chewing and swallowing. In early weaning systems calves need to begin eating some grain by 2 weeks of age to allow enough rumen development to occur before weaning at 5 or 6 weeks of age. The probe is a rigid or semiflexible tube made of plastic or stainless steel. Diets must provide enough energy to support growth and enough protein to be used for that growth. However, rough handling when using a tube feeder can injure calves. In a colostrum-fed calf, a low dose of a given pathogen results in subclinical disease no visible sickness and an immune response to the pathogen. However, antibodies in colostrum may help fight infectious organisms in the calf's digestive tract beyond 24 hours. Calf survival rates by level of serum IgG. Clean and sanitize the feeder, and then allow it to drain and dry. In contrast, it makes up only 8 percent of the stomach capacity in a mature cow. Both the type of grain and how it is processed affect starch fermentation rate. After weaning, starter consumption increases and good quality, high starch starters need to be supplemented with forage. Thank you for your submission! When using the metabolic feeding curve, the farmer can consider shortening the milk phase by two weeks, down to eight weeks of life. Effects of early colostrum feeding on intestinal E. However, the reticulum and rumen grow in size and in function; they become the most important parts of the stomach system. Whey is composed of water, minerals, lactose, and other proteins including immunoglobulins. Fortunately, there are a simple devices that can be used to quickly estimate colostrum IgG content. By 12 weeks of age, the reticulum and rumen will make up more than two-thirds of the total stomach capacity. This system allows the calf to receive a steady supply of nutrients over the first 24 to 48 hours of life, as long as it is fed casein-containing liquids. Typical composition of colostrum and transitional milk. Electrolyte supplements are often needed for calves with moderate to severe scours. What types of equipment do you perform maintenance on ahead of winter weather? In both experiments, calves fed a consistent diet grew faster and more efficiently than those fed an inconsistent diet. Before the mids, whole milk was the primary liquid feed for calves. However, because calves tend to eat big meals all at once, high amounts of starch in starter can cause acidosis if the starch ferments rapidly in the rumen. Electrolytes do not supply enough energy to be the sole source of nutrients. Research and on-farm experience have shown that this can result in restricted growth after weaning and produce calves that are similar in size to conventionally fed calves by 4 to 6 months of age. Cost per pound of gain may be helpful in comparing feeds that differ in composition or amount fed. You can administer fluid by attaching a large funnel to your end of the tube after the smooth end has been put into the stomach via the nostril. Comparison of rumen papillae development at 6 weeks in calves fed milk only A , milk and grain B , or milk and hay C. By Heather Smith Thomas — There are times you must get fluid into a newborn calf that needs colostrum or a sick calf that needs fluid and medications given orally. Calves may be started on a milk replacer when 2 to 4 days old, but the switch from whole milk to milk replacer should be gradual. Progressive Cattle magazine captures the essence of the cattle producer and ranching experience.
To successfully implement current scientific findings on metabolic programming in practice, and thus raise healthier calves with a better performance potential and higher milk yield, the more traditional dietary recommendations of feeding calves must be revised. Traditionally, feeding programs based on the principle of 3 litres per meal, with each meal including to grams milk replacer CMR per litre, were recommended. With these programs, calves receive approximately grams of CMR per day. Until , this was a common recommendation throughout the dairy sector, including automatic feeders. In addition to the low energy concentration, automatic feeders also pose another risk: calves starving due to missed milk feedings. Since the total amount of milk is distributed among four and six visits per day, each calf receives only to grams of CMR per visit. When teaching calves to use the feeder, there are always a few animals that need a few days to get used to the feeding method. They often miss one or more meals. If a calf misses its second visit and only obtains one or two meals on the next feeding day, that means instead of the desired grams per day, it often only receives half the amount of CMR. These calves do not even intake enough nutrients to cover their own energy requirement, which makes them susceptible to illness and disease. Thus, the supposed advantage of offering many small portions in the automatic feeder is also actually a risk factor in certain cases. Feeding parameters must be adjusted to the individual needs of the calf, using precise and individually adapted feeding curves. It tells how much CMR or dry matter of whole milk the calf has absorbed until day The higher this figure, the higher the future performance potential and milk yield of the calf. Under previously recommended restricted diets, calves typically gained grams per day during the preweaning phase. According to this new research however, for every grams of increased weight gain, calves, on average, produced an additional kilograms of milk in their first lactation. As a first step, every farmer should decide how intensively he or she wants to feed and raise their calves. Intensive ad libitum feeding during the first weeks is a good possibility but it may not be the right path for everyone. With this in mind, farmers can adopt one of two different feeding strategies: The economy feeding curve or the metabolic feeding curve. The standard curve of automatic feeders should allow a daily intake of 1, grams CMR in the first four weeks. This corresponds to recommendations for moderate rearing with average growth of about grams per day. This can be achieved by starting with an initial milk quantity of 6 to 7 litres per day. If this amount is used, producers should increase the CMR concentration to grams per litre in the start phase before reducing to grams prior to the actual weaning phase. After 35 days, calves should be weaned in small amounts of about millilitres per day until day 70 when they are fully off milk. With this feeding curve, each calf would consume a total of approximately 50 kilograms CMR. This feeding curve forgoes a gradually increasing feeding phase and instead feeds litres of milk per day during the start phase. In this case, the farmer accepts that calves may not retrieve and consume the entire amount at the beginning. The daily intake of CMR in the first start phase is 1, grams and higher. This enables calves to achieve a daily weight gain of 1, grams and more. With this high supply, calves convert additional CMR quantities into body mass at the ratio of 1 kilograms CMR : 1 kilograms bodyweight. The metabolic factor in the day start phase is approximately 38 kilograms CMR. In feeding curves recommended in the past, this quantity of milk powder was not even fed until the end of the rearing period, at 10 weeks. As with the economy curve, the metabolic feeding curve also integrates an early reduction of CMR concentration to prepare for the actual weaning of calves. This ensures that calves are prepared early on for the intake of concentrate feed. This process marks the start of the weaning phase. The amount of energy supplied is slowly reduced, which motivates calves to satisfy their hunger pangs by consuming dry feed. In addition, calves still continue to receive a good quantity of milk for a certain period of time, which can suppress the tendency towards mutual cross suckling. The metabolic feeding curve is ideal for weaning calves previously fed a higher plane of nutrition e. It allows producers to wean calves from a very high energy intake without the risk of growth checks. However, calves should be introduced to the automatic feeder not later than in the third week, so the weaning process can slowly be introduced. When using the metabolic feeding curve, the farmer can consider shortening the milk phase by two weeks, down to eight weeks of life. When weaning at eight weeks, the theoretical CMR consumption is approximately 56 kilograms; a week milk feeding phase would result in consumption of more than 70 kilograms, depending on the actual quantity of milk the calf intakes.
