Cattle can tolerate a few worms, but heavy infections are detrimental, Craig says. Heavy worm burdens are more likely to occur with intensive management where many cattle are grazed in small areas. Meanwhile, intensive grazing on wet pastures is ideal for worm transmission. This is often the same time it takes worm eggs to hatch and become infective again.

High cattle density puts more worm eggs in a smaller area, and the animals are forced to eat everything, even grass next to manure piles. If a pasture is used through summer for rotational grazing, the worms gain the advantage. Lightweight stocker calves are susceptible to several parasites, including Cooperia intestinal nematodes. But, as they age, cattle will develop immunity to these worms.

Bert Stromberg, a professor in the Department of Veterinary and Biomedical Sciences at the University of Minnesota, says Cooperia can significantly impact young cattle. He points to a yearling study that found Cooperia impacted weight gain by 7. Another devastating worm, particularly in the South, is Haemonchus, which can cause death loss in lightweight stocker cattle by inducing anemia, he adds.

If range-raised calves are brought to wet pastures, they could develop a high level of worms. The work compared different protocols — deworming only the cow, deworming the cow and calf, or deworming calves only.

Weaning-age calves should also be dewormed as part of their backgrounding as stockers or replacement heifers, Craig advises. Stromberg says studies show benefits of deworming weaning-age calves at least two weeks before vaccinating, thus allowing them to mount a better vaccine response.This site is operated by a business or businesses owned by Informa PLC and all copyright resides with them.

Registered in England and Wales. Number Burt Rutherford Apr 01, In hot southern climates, that hypobiosis occurs in summer, with emergence in the fall. As the weather heats up and dries out, larval activity on the pasture subsides. However, few cattlemen want to gather cows in the heat of summer and work them again, which makes spring and fall deworming, when cattle are being worked anyway, a more palatable management option. However, even in arid climates, internal parasites can flourish. Typically, the desert Southwest will get summer monsoon rains beginning in late July.

That means, in three to four weeks, hibernating worms emerge and begin shedding eggs, making pastures infective by August and September. He also recommends that cattlemen use a product that controls external parasites, as well. Wenzel is a strong advocate of getting the biggest bang for every dollar spent on a deworming program.

It may cost a little more money in the short term. By the time cows reach maturity, their immune system has kicked in and is partially controlling the negative effects that worms have. Not so with calves. By then, the calves will have picked up enough of a worm load to make deworming worthwhile.

And the cows benefit, too. According to Michelle Arnold, University of Kentucky Extension veterinarian, there may be another aspect to strategic deworming in mid-summer that cattlemen may need to consider. Mature cows need deworming once a year. She emphasizes deworming young cattle because of the effect that a worm load can have on a young, growing animal, particularly replacement heifers. That is a tremendous demand as far as nutrients go. Arnold also stresses that deworming is just part of the management equation in controlling the worm load in your cattle.

Pasture management plays a big role, too. The macrocyclic lactones, which includes the avermectin class, have a residual effect; meanwhile, the white wormers kill the adult worms in the gut and hypobiotic larvae, but are only effective for one or two days. Rotating compounds is important not just in keeping a population of worms around that will stay susceptible to chemical dewormers. It also helps control other species of internal parasites. The macrocyclic lactones are highly effective against brown stomach worms, which are the number-one internal parasite of concern to cattlemen.

One of the things we have seen with continuous use of the avermectins is that we have selected for cattle that are loaded with Cooperia. But fecal egg counts can be diagnostic, at least in young cattle. But by all means, they say, put your money into deworming. New At Beefmagazine. When To Graze Spring Pasture. Strategic Deworming: Time It Right. Load More.Gestation length does vary by breed and by sex of the calf.

Gestation length ranges from to days. For most breeds, days would be common. Cows carrying bull calves tend to have a slightly longer gestation compared to cows carrying heifer calves. Cows that calve in a body condition of less than 4 scale 1 to 9 have a longer post-partum interval.

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. There needs to be some caution when feeding this forage to pregnant beef cows.

If the forage is high in nitrites, then it needs to be mixed with a forage that is much lower in nitrates or a forage that does not contain any nitrates. Using other forages, the nitrates can be dilute to safe levels and fed. The easiest way to dilute the forage that has the nitrates is to grind and mix with the other forages.

Keys to feeding a forage that contains nitrates: Dilute the forage that has nitrates to a safe level. Adapt cattle slowly to a forage that contains the high nitrates. Never allow cattle that are hungry access to forages that contain high nitrates. Pine needles consumed by cows during late pregnancy can cause abortion, or premature calving. Producers need to be aware that few options exist to decrease the risk of pine-needle-induced abortion other the physically isolating cows from exposure during late pregnancy.

Exposure to any source of pine needles, whether they are fresh, dry, weathered, on the ground, on standing trees, or on fallen trees during late pregnancy should be avoided. The culprit is isocupressic acid, a yellow, oily substance in pine needles.

Identification of the culprit is the first step in developing an antidote. As far as I am aware, the antidote is not yet available. Answer from Some BVDV MLV products state on the label that they can be safely administered to pregnant cattle if the cattle had also received the vaccine prior to breeding.

Although some cattle producers prefer to vaccinate during fall work for convenience; it makes the most sense from a BVDV control standpoint to vaccinate prior to breeding so that cattle have the best protection during early pregnancy.

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.

Performance improvement plan should i quit

First-calf heifers have a longer PPI compared to mature cows, about 10 days longer if she has no calving difficulty and is in good body condition.

If cows are exposed to bulls bull exposure after calving, then the PPI is usually shorter by may be as much as 10 days shorter. 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. I don't think many cows will come into heat estrus before 35 day post calving.

You can "jump start" estrous cycles with progestins and gonadotropins GnRHbut this will only happen in females that are close to begin cycling.!

Use of these programs has the potential to induce estrous cycles in cows that are close to cycling. So, nutrition is very important, have cows in at least body condition score 5 at calving and don't skimp on the groceries after calving.

Ionophores such as Rumensin or Bovetec have a positive impact on the reproductive axis, at least there are experiments using the heifer that demonstrate this, so consider using an ionophore in the ration after calving.

Expose cows to sterile bulls as soon after calving as possible. These considerations are all for not if the cows have not been managed properly from a nutritional perspective. 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. A review of these studies conducted over the last several decades along with new research indicates the association among BW, puberty and heifer pregnancy rate appears to be changing over time.If you own a pregnant cow, having a strong awareness of the parturition process and what to expect is extremely important.

Always closely supervise your cow during the calving process, from start to finish. When a cow is ready to go into labor, she might display some telltale visual and behavioral hints. Labor in cows often takes no more than eight hours. If you notice that your cow's vulva has increased in size, then there's a good chance her body is on the verge of calving.

This size increase is often referred to as "springing. Apart from the size change, her vulva might also emit a transparent substance. Threads of mucus might conspicuously dangle from it, too. One common sign of upcoming labor in cows is a lack of appetite, similarly to animals of many other species.

If your cow seems to have no interest in eating her meals, pay attention to her, because labor is probably right around the corner. Changes in behavior also often signify a cow that's ready to give birth.

She might seem a lot more antisocial than usual, for example. She might get away from the herd in an attempt to find a calm location. She also might behave in an uncharacteristic antsy and fidgety manner -- totally unable to be still for even a minute.

She might lie down repeatedly, only to stand up again within a minute. Stomach pain is often a big indication of nearing labor in cows. Your cow might express her pain through constantly booting herself straight in the belly. These symptoms are especially prevalent in heifers -- youthful female cows that have never calved before. Cows that are preparing to give birth often exhibit prominent udders that appear packed with milk.

This "bagging up" process often takes place weeks before cows are due to give birth. For some cows, however, it can happen within the span of one day prior to parturition. It isn't uncommon for older female cows to not display any clear indications of labor.

If a cow has given birth many times previously, you might not notice anything out of the ordinary. She might, however, seem especially vigilant. She also might situate her body in an atypical manner when lying down.

A handful of key body language hints often point to parturition in cows. If a cow stands with her back rounded and tail elevated, she might be ready. Her tail also might seem a lot more mobile than usual, perhaps constantly shifting positions. Pregnancy in cows typically lasts for between and days. Note that cows pregnant with female offspring usually have briefer gestational periods than those pregnant with male offspring, although the difference isn't too substantial.

However, by controlling the only location in the life cycle that can produce eggs adultswe can effectively reduce pasture contamination if weather conditions are right and positively impact subsequent cattle generations. The timing of when adults appear varies based on available moisture and environment.

Work closely with your veterinarian to determine the best time to administer. Why should producers be concerned about protecting their cattle from parasites? Parasites are found in all forage situations Internal parasites cause numerous problems: Suppress appetite and reduce feed intake Reduced nutritional intake through decreased ability to digest and absorb nutrients Inhibit immune system to cause cattle to respond poorly to vaccines and disease challenges Reduced nutrition intake impacts many aspects of animal performance including: Gain Feed efficiency Immune response Reproduction Why invest in a brand name parasite control product?

Consult your veterinarian for assistance in the diagnosis, treatment and control of parasitism. Ivermectin Pour-On for Cattle ivermectin topical solution delivers internal and external parasite control in one convenient low-volume application.

Ivermectin Pour-On for Cattle contains ivermectin, a unique chemical entity. Ivermectin is a member of the macrocyclic lactone class of endectocides which have a unique mode of action. Compounds of the class bind selectively and with high affinity to glutamate-gated chloride ion channels which occur in invertebrate nerve and muscle cells. This leads to an increase in the permeability of the cell membrane to chloride ions with hyperpolarization of the nerve or muscle cell, resulting in paralysis and death of the parasite.

Compounds of this class may also interact with other ligand-gated chloride channels, such as those gated by the neurotransmitter gamma-aminobutyric acid GABA.

The margin of safety for compounds of this class is attributable to the fact that mammals do not have glutamate-gated chloride channels, the macrocyclic lactones have a low affinity for other mammalian ligand-gated chloride channels and they do not readily cross the blood-brain barrier.

Ostertagia ostertagi including inhibited stage adults and L 4. Ivermectin Pour-On for Cattle has been proved to effectively control infections and to protect cattle from re-infection with: Oesophagostomum radiatum and Dictyocaulus viviparous for 28 days after treatment; Cooperia punctata and Trichostrongylus axei for 21 days after treatment; Ostertagia ostertagi, Haemonchus placei, Cooperia oncophora and Cooperia surnabada for 14 days after treatment; Damalinia bovis for 56 days after treatment.

Ivermectin Pour-On for Cattle controls horn flies Haematobia irritans for up to 28 days after dosing. For best results Ivermectin Pour-On for Cattle should be part of a parasite control program for both internal and external parasites based on the epidemiology of these parasites.

Consult your veterinarian or an entomologist for the most effective timing of applications. The dose rate is 1 mL for each 22 lb of body weight. The formulation should be applied along the topline in a narrow strip extending from the withers to the tailhead.

For the mL and 1 Liter containers, see the diagram below. When body weight requires a drug product volume that is between the measuring markings, use the next higher increment. Studies conducted in the U. Based on plasma levels, the topically applied formulation is expected to be at least as well tolerated by breeding animals as is the subcutaneous formulation which had no effect on breeding performance.

This product should not be applied to self or others because it may be irritating to human skin and eyes and absorbed through the skin. To minimize accidental skin contact, the user should wear a long-sleeved shirt and rubber gloves. If accidental skin contact occurs, wash immediately with soap and water. If accidental eye exposure occurs, flush eyes immediately with water and seek medical attention.Discussion in ' Goats ' started by waygr00vyDec 14, Log in or Sign up.

Welcome to the Homesteading Today Forum and Community! Dec 14, 1. Messages: OK, so i have been using ivermectin but it really doesn't seem to be working any more. I just bought some cydectin, the cattle pour on type, to worm the herd with, but I was reading through posts and some people questioned its safety on bred does? Most of my girls are bred, and I would really hate to cause problems, but I also need to worm them with something!

I have heard safeguard is basically innefective at least in my area. I also have valbazen but that is also not for pregnant does. Dec 14, 2. Messages: 9, I do use Cydectin on anything pregnant that needs wormed I just wormed my herd of dry does last month with Cydectin, they were all pregnant, their is 60 in the herd.

No problems. I have been doing it for years. Dec 14, 3. Messages: 1, I have also used the cattle pour on Cydectin, no problems.
