Feeding trace mineralized salt plus recommended amounts of calcium and phosphorus Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust o…Phosphorus
How do you feed a pregnant cow?
When you’re feeding a pregnant cow, you’re feeding for two. While protein requirements for all pregnant cows increase in the later stages of gestation, they’re highest for young cows. This can be managed by separating the first- and second-calf heifers from the main herd, and supplementing the younger females with protein,...
What nutrients does a cow need in early gestation?
A cow’s nutrient requirements in early gestation aren’t much different from her maintenance requirements, but her needs increase as the fetus inside her grows. And if a cow is lactating, she needs a much higher level of protein and energy than during pregnancy.
Does pregnant cow nutrition affect calf health?
Decisions a cattle producer makes about pregnant cow nutrition now can have major impacts on calf health in the spring and cow fertility during the next breeding season.
What do you feed a newborn calf after birth?
The calf should be fed the cow’s colostrum (the milk produced 4-5 days after calving) within 30 minutes to two hours of birth. If the calf isn’t getting enough colostrum and later milk, pooled colostrum or milk from other cows can be used. Artificial colostrum can also be procured from markets.
What is the best feed for pregnant cows?
Hay. Hay, a staple of the cattle diet, is often fed to pregnant cows even if they have access to pasture. The average cow will eat between 20 and 30 pounds per day of good-quality hay such as alfalfa.
How much should I feed a pregnant cow?
During the last two trimesters of pregnancy, mature cows generally consume 2 to 2.5% of their body weight on a dry-matter basis. For a 1,200 lb cow, this equates to 24 to 30 lb of hay per day on a dry-matter basis, or approximately 27 to 33 lb per day on an as-fed basis.
How much protein do pregnant cows need?
Typical mature, late-gestation cows weighing about 1,400 pounds will need approximately 2.5 pounds of protein intake a day. Some 60 to 70 percent of the protein should break down in the rumen to supply sufficient nitrogen for rumen microbes.

Is salt good for pregnant cows?
The sodium supplement increased the birth weight of their calves but after 6 weeks there was no difference between treatments in calf weight. In addition to milk, calves in both treatments were offered a choice of concentrates with normal or high sodium concentrations (5·8 and 10·8 g/kg dry matter, respectively).
Is molasses good for pregnant cows?
M8U (molasses plus 8% urea) M8U is a common supplement for survival/drought feeding, spike feeding pregnant heifers and cows, and keeping growing steers and heifers growing slowly during the dry season.
Can ivermectin be used on pregnant cows?
Can You Use Ivermectin On Pregnant Cattle IVOMEC Super Injection for Cattle will not affect the fertility of cows and bulls and can be given to all ages of animals. IVERMECTIN Pour-On for Cattle is formulated for external use only in can you. Ivermectin is reported as safe drug in ruminants during pregnancy.
What to feed cows before calving?
Hay should be tested for protein, and cows and heifers should be supplemented accordingly. By-product feeds or straw may be cost-effective in some situations. Some by-product feeds - corn distillers solubles, feather meal, for instance - are high in protein and by-pass protein.
How do you take care of a pregnant cow?

What is the best grain to feed cattle?
Corn, oats, and barley are the primary grains fed to cattle. Oats, which has a lower energy value due to its high fiber content, is considered the "safest" grain in regards to potential digestive disturbances.
What is a good source of calcium for cows?
Most grasses are adequate in calcium. Legumes such as alfalfa, peanut, clover and soybean hay are good sources of calcium, but corn silage and sorghum silage are poor sources of calcium. In general, most concentrates are relatively poor calcium sources.
Why do cows need salt blocks?
Dairy cows need salt to create milk, and beef cows need salt to gain their proper weight. Calves with a salt deficiency have a much lower weaning weight than calves with access to salt. Like other animals, cows use salt to maintain their bones, muscles, and nervous systems.
Do cows eat more when pregnant?
Cows need more and better-quality feed as pregnancy progresses. Nutrient requirements in early gestation are not much different from maintenance requirements, but as the fetus grows larger, the cow's nutrient needs increase.
How much should you feed a nursing cow?
The recommendation is to feed about 1 lb of concentrate per 4 lb milk production with a maximum of 16 to 20 lb/cow/day. For late lactation cows, we suggest a 1:5 or 1:6 grain to milk ratio. The relative price of milk in relation to concentrates and body condition should indicate the amount of concentrate to feed.
What to feed cows before calving?
Hay should be tested for protein, and cows and heifers should be supplemented accordingly. By-product feeds or straw may be cost-effective in some situations. Some by-product feeds - corn distillers solubles, feather meal, for instance - are high in protein and by-pass protein.
How many pounds of cows is 20 cubes?
Cattle Breeder 20 Cubes Our top-of-the-line source of all-natural, high quality protein and energy with high levels of vitamins and minerals to help balance nearly adequate forage quality. Feed at 2 lbs per head per day. This product work especially well in winter for improved weight maintenance and breed back.
What temperature should cows be kept at?
Even with heavy winter coats, nutrient requirements for cows begin to increase when the temperature is below the “lower critical temperature” of about 18 F.
Why do cows need colostrum?
A separate study found that cows with inadequate body condition produced poorer-quality colostrum, compared with cows in good body condition. Poor body condition resulted in a reduced ability to transfer immunity through colostrum to calves of underfed cows. Newborn calves need adequate colostrum because it contains antibodies and other proteins that protect calves from disease until their own immune system is totally functional.
How much TDN should a cow need?
This means the same 1,300-pound cow that needed 12.5 pounds of TDN per day at a temperature of 18 F may need up to 14.8 pounds of TDN per day at a temperature of 0 F.
What do producers need to know about calving?
Producers need to review their anticipated calving dates, cow body condition scores and cows' diet. Decisions a cattle producer makes about pregnant cow nutrition now can have major impacts on calf health in the spring and cow fertility during the next breeding season.
Do cows get pregnant after calving?
Studies also show that the need for good nutrition during pregnancy carries over to fertility the following breeding season. Cows that are thin at calving have a greater chance of not becoming pregnant the following breeding season, compared with cows that calve in good body condition.
Does fewer nutrients during gestation cause lighter birthweights?
Although some producers argue that providing fewer nutrients during gestation will lead to lighter birthweights and, therefore, fewer calving difficulties, that isn’t always the result, according to Dahlen.
Do heifers need to be on a greater plane of nutrition than older cows?
Therefore, thin cows and heifers need to be on a greater plane of nutrition than older cows in good condition. Dahlen recommends producers consider sorting heifers and thin cows into their own group for feeding if possible. If not, producers should try to spread feed out over a larger area to reduce the incidence of thin cows being pushed away ...

What is the best way to feed a female reproductive tract?
Feeding trace mineralized salt plus recommended amounts of calcium and phosphorus is essential. Balanced and laxative rations should be fed to maintain the normal tone of the reproductive tract.
Why should pregnant cows be watched?
Pregnant Cattle should be watched carefully, particularly during the last stages of pregnancy to avoid abortion due to fights or other physical trauma.
How to keep a calf warm?
If cold, keep the calf warm by rubbing and drying the calf with a dry cloth or gunny bag. Tie the calf’s umbilical cord about 3-5 cm away from its body. Make an incision 1 cm below the ligature and apply tincture of iodine to avoid infection. Advertisement.
How long after calving should a cow have milk?
Advertisement. The calf should be fed the cow’s colostrum (the milk produced 4-5 days after calving) within 30 minutes to two hours of birth. If the calf isn’t getting enough colostrum and later milk, pooled colostrum or milk from other cows can be used. Artificial colostrum can also be procured from markets.
How long after calving can you feed an animal?
After calving, the animal must be encouraged to move to the manger for feeding, especially on the day of calving and the first two days after calving. Provide clean drinking water and protection from thermal stress. If playback doesn't begin shortly, try restarting your device.
How long should a cow be on milk replacer?
Calves should be fed whole milk/milk replacer at least up to 2 months.
Why should a milk animal have a proper and organized feeding regimen?
Milch animals should have a proper and organized feeding regimen to enable maximum lactation.
What do cows need to calve?
Ruminant researcher Dr. Tim McAllister at the Lethbridge Research Centre says protein requirements are fairly low in the fall for spring-calving cows, around eight per cent. “They can live on fairly poor forage at that time, and fall pastures are generally adequate until they get further along in pregnancy. Then it’s just a matter of supplementing with better-quality hay. The level of protein never has to be higher than about 12 per cent, which they would need right before calving. High-quality grass hay, or a grass/alfalfa mixed hay would be ideal for cows in late-stage gestation. Cows are very efficient in their utilization of nitrogen,” he says.
How much urea should cows eat?
For cows to use urea efficiently, three or four pounds of grain should be fed per head daily. “Cows need the soluble carbohydrates in order to use the urea,” says Yaremcio. “If you are using urea in a ration, no more than 25 per cent of the total protein should come from urea.
What is DDG in cows?
You need to know the form or structure of that protein supplement coming as dried distillers grain (DDG) plus solubles. “There are other protein sources such as hull products (pea hulls or oat hulls). They may not be as high in protein and may be higher in fibre, but will certainly add to the protein in the diet to meet cows’ requirements.
Why is it important to test cows for protein?
Meeting nutrient requirements, especially protein, is essential to maintain an efficient and productive herd. Feed testing is crucial. “When you get the results, you can use a ration-balancing program such as CowBytes (available from Alberta Agriculture and Forestry) to avoid unwanted problems and unnecessary costs. If a producer has questions regarding proper supplementation and balancing the diet for pregnant or lactating cows, talk with a feed mill nutritionist, government extension person or private consultant who can give advice on how to adjust the feeding program when using unusual or multiple feed sources.”
Do cows need different levels of nutrition?
Cows require different nutritional levels at different stages of gestation. Nutrient requirements in early gestation are not much different from maintenance requirements, but as the fetus grows larger the cow’s nutrient needs increase. And if a cow is lactating, she needs a much higher level of protein and energy than when she is pregnant.
Do ruminants need protein?
ADVERTISEMENT. They do need an adequate level of protein to “feed” the microbes in the rumen that break down forages into usable nutrients and get the energy benefit from dry feeds like mature grass or even straw.
Do cows need more protein?
And if a cow is lactating, she needs a much higher level of protein and energy than when she is pregnant. Protein requirements for pregnant cows increase during later stages of gestation, and are even higher for young cows. If you are keeping the young cows (the ones that will be first and second calvers) separate from the main herd, ...
Why is it important to provide protein to cattle?
BODY CONDITION. “It’s important to provide protein to enable cattle to get full feed intake (and therefore adequate energy) but we also need to monitor body condition,” says Drewnoski. “If body condition is not maintaining, you may need to increase the protein, to increase feed intake.
Why do cows lose weight when they are pregnant?
Pregnant cows need adequate protein so they can eat enough and have enough energy.
How much protein do cows need?
“Most mature cows in mid-gestation will need about 1.5 pounds of protein per day. In late gestation they probably require closer to 2 pounds per day. When lactating, their requirements are even higher and will vary depending on the level of milk production,” she says.
How much protein does a cow need to produce milk?
Cow size also makes a difference. “A 1300-pound cow in early lactation producing 10 pounds of milk requires a little over 2.25 pounds of protein and this would increase to almost 3 pounds if you add another 10 pounds of milk. She’d also need more energy.” The amount of milk produced makes a big difference; it takes a lot more protein and energy to feed a lactating dairy cow than to feed most beef cows, and some beef cows give more milk than others, and must be fed accordingly.
Does fetal programming affect cows?
Mary Drewnoski, beef systems specialist, University of Nebraska-Lincoln, says there’s also a fetal programming factor; the amount of protein a cow gets during gestation affects fetal development. “Research data suggests that for cows on dormant range pastures (mature grass) we’ll see negative effects on their progeny if they don’t receive adequate protein; it has long-term consequence on those calves,” she says.
Do cows give more milk than other cows?
The amount of milk produced makes a big difference; it takes a lot more protein and energy to feed a lactating dairy cow than to feed most beef cows, and some beef cows give more milk than others, and must be fed accordingly. “It’s challenging today to find beef cows with moderate milk EPD.
Do cows need nutrient levels?
Nutrient requirements in early gestation are similar to maintenance requirements, but as the fetus grows, the cow’s nutrient needs increase . A lactating cow needs a much higher level of protein and energy than when she’s pregnant. Mary Drewnoski, beef systems specialist, University of Nebraska-Lincoln, says there’s also a fetal programming factor;
How long does it take for a cow to postpartum?
So with all that in mind, the postpartum interval, if conditions are ideal, for beef cows is between 50 and 60 days for an average of 55 days. First-calvers will be at least 10 days longer.
How long is the postpartum period in cows?
Not an easy task to accomplish. Usually the length of the post-partum interval (PPI, time from calving to the first estrous cycle) is 45 to 55 days in beef cows. If cows are in good body condition at calving, then the PPI would be in the 45 to 50 day range and if in poor condition, the PPI would be longer.
Why are cows open?
Open cows are usually due to mis-management of the nutrition program. Minerals are important, but I rarely see large reductions in reproductive performance due to minerals alone, especially in Nebraska.
How long does it take for a cow to invet?
It has been documented in beef cows that uterine involution is not completed by 20 days post-calving, but the uterus is back to its non-pregnant size by 30 days post-calving. Another 10 or so days is needed to complete uterine involution and be prepared for another pregnancy.
What is a synchronization program for cows?
There are synchronization programs for cows that use CIDR (progesterone) and GnRH (Cystorelin, Factrel, Fertagyl, OvaCyst). Use of these programs has the potential to induce estrous cycles in cows that are close to cycling.
What is the body condition score for a first calf female?
Calf first-calf-females in a body condition score of 6 (on 1 to 9 scale). A lot of the diets that I see for these females after calving is often deficient in energy. Grass hay and alfalfa don't not have enough energy, so you will need to added some corn, distillers, gluten, silage, etc to the diet.
What is the ratio of bull to cow?
Bull to cow ratio. For young bulls, 1:12 to 1:15; older bulls 1:25 to 1:30. Did you have any breeding pastures that had only one bull for the entire breeding season? Maybe the bull was good early and got hurt or sick later in the breeding season. Did you run 2 yearling bulls in one breeding pasture? This is probably not the best management strategy.
What is the role of trace minerals in cows?
As I've stated in past columns (August, September, October 2000), trace minerals play a crucial role in the immune system, cow fertility, colostrum and other aspects of production . One important factor to remember in supplementing the pregnant cow before calving is that response time is a key factor.
What is the most important period in the life of a newborn calf?
Few things are as important as pre-calving nutrition. The last trimester of gestation, particularly the last 45-50 days, is the most critical period in the life of this year's newborn calf and also next year's calf. What is done for the fetus at this time impacts its survivability and long-term health and performance.
How long before calving should I supplement?
I advise my clients to begin supplementation or feeding a mineral 30-45 days before calving and continuing through breeding.
What is the importance of pre-calving BCS?
The importance of pre-calving body condition score (BCS) is noted among my clients in drought areas. For the majority of cows with an average BCS (5-6), pregnancy rates were average with a large number performing 3-5% above average despite poor spring and summer range conditions.
Does a heifer's diet make it smaller?
While the calf will likely be smaller at birth, it will also be weaker. And, the heifer will be smaller and less mature. Producers have told me that high-protein diets cause bigger calves.
Is hay good for cows?
Hay should be tested for protein, and cows and heifers should be supplemented accordingly. By-product feeds or straw may be cost-effective in some situations. Some by-product feeds - corn distillers solubles, feather meal, for instance - are high in protein and by-pass protein.
Do heifers recover from calving?
I attribute this to an easy winter and good BCS numbers. Thin cows at calving, especially first- and second-calf heifers, never recover the body condition necessary to cycle and breed in poor range conditions, research shows.
