4 steps for properly tube feeding colostrum in first 24 hours

4 steps for properly tube feeding colostrum in first 24 hours

Tube feeding a newborn calf can be tricky. Here are four tips to avoid trouble when administering colostrum through a tube and ensuring the long-term health and survival of the calf.

It seems like every calving season, there is always a calf or two that fails to get up and nurse. Perhaps the labor was stressful. Maybe the calf is slow to figure things out. Possibly the first-calf heifer is confused and kicks at the calf. Whatever the reason, it’s hard to avoid having to milk out and tube feed a few calves every year.

It’s critical to get colostrum in the calf within 24 hoursafter birth. This ensures the passive transfer of immunity before the closure of the intestine, which allows the calf to absorb good quality immunoglobulin, explains Michelle Arnold, DVM, University of Kentucky ruminant veterinarian, in a recent article for the Ohio State University Extension Beef Newsletter.

BEEF Roundtable: Considerations for a successful calving season

Arnold says there are four key factors that contribute to the goal of successful passive transfer of immunity and ultimately determine the health and survival of the newborn calf.

1. Quality

Arnold recommends, “Feed a high quality colostrum with a high immunoglobulin concentration (>50 g/L) or use of a good quality powdered colostrum replacer (not a supplement).”

2. Quantity

She also suggests, “Feed an adequate volume of colostrum (2 quarts to beef calves at birth followed by 2 more quarts in 4-6 hours).”

3. Quickly

She advises producers to, “Feed colostrum promptly after birth (within 1-2 hours and again by 6 hours maximum).”

4. Quietly

Finally, she warns, “Passing the tube too quickly may result in damage to the laryngeal area and passage into the trachea and lungs. Handling the calf correctly minimizes this risk.”

To achieve the appropriate quality and quantity as quickly and quietly as possible, she also gives advice on how to properly handle the calf, insert the tube, check placement of the tube, administer the colostrum, remove the tube, and clean the equipment, which you can read here.

Arnold concludes, “Learning to use an esophageal feeder may mean the difference in life or death to a newborn calf. Esophageal feeders can also be used to administer vital electrolytes to scouring calves if reluctant to nurse a bottle.”


Feeding Poor Quality Hay

Posted by Travis Meteer on http://web.extension.illinois.edu/oardc/eb275/entry_10699/

Remember what a miserable year it was trying to get dry hay put up? In west-central Illinois, the rainy weather made it near impossible. In the month of May, we recorded rainfall on 15 of 31 days. In June, rainfall was recorded on 19 of 30 days. Here at the Orr Research Center in Perry rainfall totaled 26.5 inches for the months of May, June, and July. That is 68% of the normal annual rainfall in just 3 months.

It doesn’t take a rocket scientist to conclude there are copious amounts of poor quality hay to be fed this winter. So what should you be aware of? What can you do to offset the lower nutritive value of this year’s hay?

First, a producer should take time to visually appraise the hay. Go ahead and smell it too. Is it moldy? Does it smell musty? Are the stems big and thick? Are weeds present? Are they woody? Are they spiny or thorny?

If the answer to any of these questions is yes, then hay intake will be lower. Nutritive value of the hay will likely be lower as well. If the mold infestation is severe, I would not risk feeding it to pregnant or lactating cows. I would consider not feeding it at all. If you must feed it, dilute it or roll it out to allow the cows to pick what they want. Offer them plenty of other feed choices while feeding high risk hay.

Another lurking problem is ergot. Nearly every pasture I was in this spring had some level of infestation. As a result, be looking for black seed heads that will resemble mouse droppings. If you see this, consider not feeding the hay or diluting it with other feedstuffs that are not contaminated.

It would be wise to approach this winter feeding period with a ration that has several components if possible. A diet of hay only has too many risks this year. Hay alone will likely not meet nutrient requirements either. I would consider feeding cornstalks, corn silage, grains, and co-products with your hay. Look at your local bids for feedstuffs. Formulate a least-cost ration with three or four ingredients. This should help mitigate risk of cows consuming too much of a contaminated feed.

I would recommend feeding DDGS or a co-product blend when greater than 7 pounds of corn is needed. Negative associative effects can occur when feeding corn grain greater than 0.5% of cow body weight.

Table 1 and 2 show the amount and cost of supplementing hay with differing energy content.

Table 1. Amount and cost of supplement to meet energy requirements for gestating 1400lb. cow

Corn Price = $3.80/bu.

DDGS Price = $130/ton

Low intake = 1.5% of cow BW instead of 2%

545.7$0.394.8$0.31

468.2$0.567.0$0.45
46, low intake11.9$0.819.6$0.74

Corn Price = $3.80/bu.

DDGS Price = $130/ton

Low intake = 1.5% of cow BW instead of 2%

Grinding poor quality forages can help increase intake. Be aware of the cost associated with grinding (normally around $10/bale). Also, grinding and mixing hay with other ingredients makes it more difficult for the cow to sort around dangerous components. Thus, it would not be wise to grind moldy or ergot-infested hay and incorporate at high levels of the diet.

Be mindful of the concerns of this year’s hay crop: lower nutritive value, potential mold or ergot contamination, and lower intakes. Understanding the quality of hay can help farmers save cost on supplement, ensure cow’s nutrient requirements are met, and avoid under-supplementing or over-supplementing that may cause poor BCS and subsequent reproduction.

 


5 factors affecting winter supplementation in beef cattle

5 factors affecting winter supplementation in beef cattle

As winter weather sets in, here are five factors to consider when supplementing the cow herd.

In South Dakota, we’ve been experiencing a mild December so far. With little snow cover, our cattle are still grazing on corn stalks, and aside from a few mild winter storms, we haven’t had to feed too much hay as of yet. Aside from keeping waterers chopped out, we’ve just had to worry about offering lick tubs as supplemental nutrition.

I realize that the weather can change on a dime, and as soon as a major blizzard hits or the typical South Dakota winter chill sets in, we will soon need to feed more hay and increase our supplementation of the cow herd, particularly as they enter late gestation.

When cattle get wet from snow and are exposed to colder temperatures and bitter winter winds, energy requirements increase in the beef herd. There are many factors that impact the type and amount of energy cattle may require, including these five critical factors:

1. Forage quantity

According to Steve Hammack and Ron Gill, Texas A&M University Extension beef cattle specialists, “The amount of available forage obviously affects the need for supplemental feed. If grazing or hay will be limited, take immediate action. Reduce the number of animals in order to lessen the need for supplemental feeding of the remaining cows. As forage supply declines, the opportunity for animals to selectively graze decreases, and so does diet quality. Then, supplementation may become necessary even if animal numbers are reduced.”

2. Forage quality“Poor quality forage has less than 6-7% crude protein (CP) and is low in digestibility, with less than 50% total digestible nutrients (TDN),” say Hammack and Gill. “These deficiencies limit the amount of such forage that an animal can eat. Because both consumption and nutrient content of poor quality forage are low, supplemental needs are high. The amount a cow can eat in a day ranges from as little as 1.5% of body weight for very low quality forage to near 3.0% for very high quality forage. The typical amount is 2.0-2.5%.”

3. Body condition

Hammack and Gill write, “The level of body condition (amount of fat) affects supplemental requirements. Low body condition markedly increases the need for supplemental nutrients, and meeting such needs often is cost prohibitive. Moderate body condition significantly reduces or eliminates the need for supplements. Fleshy cows generally need little if any supplement and the daily amount of forage required often can be reduced. If forage consumption is not reduced, higher production is possible or reserves of stored body energy can be maintained.”

4. Milking level

“Higher milking cows can consume somewhat more forage, but not enough to com- pletely satisfy extra needs,” say Hammack and Gill. “When forage quality is inadequate, higher milking cows need more supplement; from 50% to 100% more may be required for high versus low milk production in cows of the same body size.”

5. Age

“Young animals are still growing and require extra nutrients, but their body size is not as large as mature animals,” they write. “Because of their smaller body size, growing heifers cannot consume as much forage as mature cows. For these reasons, young females require higher quality diets than mature cows and often require more and different supplements.”

In an article for Texas AgriLife Extension, Hammack and Gill explain the various supplementation options and how to calculate how much is needed based off the above factors. Read the entire article here.

October’s timely tips

By Dr. Roy Burris, University of Kentucky Beef Extension

Spring-calving herds

• Schedule a pregnancy examination of cows if not done previously. Winter feeding costs can be minimized by eliminating open cows prior to winterfeeding.

• If you have already done a preweaning working, revaccinate (booster) calves as needed. Treat calves for internal and external parasites. If you vaccinate calves yourself, be sure to store, handle and administer vaccines properly.

• Wean calves before cows lose body condition.

• Obtain weaning weights of your calves and enter. Weaning is the time to do your first round of culling and selecting breeding stock. You can eliminate obviously inferior calves, especially those with wild or nervous dispositions. Consider the number of heifers that you will need to save for your cow herd. Bulls which are old, unsound, roguish, etc. can be culled now. It is not too early to begin thinking about replacements now.

• Use a good record keeping program. Keep good records and treat your cow-calf operation like a business.

• Evaluate the body condition of your cows and improve their condition prior to winter.

Fall-calving herds

• The calving season should be in full swing for fall calvers. Check cows frequently. Identify calves and commercial males should be castrated and implanted.

• It is time to get everything ready for the fall-breeding season, too. Line-up semen, supplies, etc. now and get your bulls ready to go (don’t forget their breeding soundness evaluation).

• Put fall-calving cows on accumulated pasture before the breeding season. This has generally been a good year for moisture. Be sure to save some grass in the breeding pastures.

• Obtain yearling measurements (weight, hip height, scrotal circumference, etc.) on replacement animals—especially for registered ones, check pelvic areas, too.

Stockers

• If you are purchasing weaned/stressed calves, have your receiving/feeding program in place. Feed a stress ration which contains at least 13% protein and is fairly energy dense.

• Manage to keep newly weaned and/or purchased calves healthy. Calves should be penned in a small lot with adequate feed, water and shade to reduce stress. Careful handling and comfortable, uncrowded conditions can decrease stress.

• When newly-weaned calves are purchased in the fall, sickness and death loss can be a big problem. Work with your veterinarian on a health and receiving program. Consider purchasing CPH-45 feeder calves which are preweaned, vaccinated, bunk-adjusted and treated for parasites.

• Watch calves closely for a few weeks after their arrival. Have a treatment program ready for any health problems. Early recognition of sick cattle improves their chance of recovery. Watch for drooped ears, hollow appearance, reluctance to rise, stiff gait, coughing and dull or sunken eyes. A good “receiving” program is essential to profitability.

General Reminders

• Remove fly-control eartags from all animals, dispose of according to instructions on package. Treat for grubs/lice.

• Avoid prussic acid poisoning which can happen when frosts rupture the plant cells in sorghums, sorghum-sudan hybrids, sudangrass and johnsongrass releasing prussic (hydrocyanic) acid. Fields can be grazed after the plants have dried up after a frost. New growth that occurs in stalk fields is potentially dangerous whether frosted or not.

• Take soil samples for soil analysis to determine pasture fertility needs. Apply phosphate, potash and lime accordingly.

• Test hay quality and make inventory of hay supplies and needs. Make adjustments now – buy feed before you run out in the winter.

• Do not harvest or graze alfalfa now in order for it to replenish root reserves.

5 questions to ask before grazing corn stalk residue

5 questions to ask before grazing corn stalk residue

Here are five questions to ask before turning the cows on stalks, including: 

1. What’s left in the field? 

After the corn crop has been harvested, it’s good to know what’s left for grazing. It’s estimated that approximately 50% of the weight of the total corn plant remains in the stalk, leaf, cob and husk components. According to a report from Iowa State University’s Extension Beef Center, “For each bushel of shelled corn produced per acre, 50 pounds of residue is also produced. For example, an acre yielding 120 bushels of shelled corn per acre will produce approximately 6,000 pounds of corn residue.”

2. How long will it last?

With good weather conditions, it’s reasonable to assume that 1 acre of corn residue will provide 60 days of grazing for a 1,000-pound animal, according to the report. In the article from Iowa State University, “Mature cows in the middle trimester of gestation that are in desirable body condition typically maintain their body weight and may gain up to 1 pound per head daily. As the grain component is consumed and availability of husks and leaves declines, protein supplementation may be needed to maintain body condition.”

3. When should I supplement?

Fall calving cows may need protein and energy supplementation, and because corn stalk residue is typically low in a number of minerals as well as vitamin A, a balanced mineral and vitamin mix should be offered free choice. According to the report, “To determine if supplementation is necessary, observe the manure. If little or no corn is visible, protein supplementation should be considered. Sources include alfalfa, corn gluten feed, distillers’ grains.

4. How can I extend the grazing time?

Cattlemen should consider strip grazing to make the corn stalks last longer and offer a more uniform quality of diet. Limiting the amount of stalks the herd can graze at once will force them to be more efficient and consume both the high and low-quality components of the residue. Strip grazing can also limit the damage on the field due to mud or icy conditions.

5. Should I be worried about nitrate toxicity?

According to the report, “Another issue can be nitrate toxicity—especially during drought conditions. The highest level of nitrate concentration in the corn plant is in the lowest part (18-24 inches) of the stalk. This area is typically the last to be grazed by cattle. Therefore, the potential for nitrate issues is unlikely. Soil compaction can also be a concern. Recent research from the Iowa State University Leopold Center for Sustainable Agriculture suggests that compaction is not an issue once the ground is frozen. Prior to freezing, there is potential for slight reduction in yield for no-till soybeans, although there was no difference in soybean yield in conventionally tillage systems.”
