    The estrogenic mycotoxins zearalenone and zearalenol interfere with conception and implantation, causing infertility, embryonic death, and reduced litter size, but rarely, if ever, abortion. Another class of mycotoxins, the fumonisins, causes acute pulmonary edema in swine; sows that recover from the acute disease often abort 2–3 days later. ABORTION DISEASES OF RANGE CATTLE E. J. Bicknell,1,2 C. Reggiardo,2 T. H. Noon,2 G. A. Bradley,2 F. Lozano– Alarcon,2 Diagnostic success rates of only 25–30% attained by diagnostic laboratories around the world verifies the fact that determin-ing the cause of abortion in cattle can be difficult. Abortion frequently results from.

Fitch; Agglutination Test in the Diagnosis of Infectious Abortion in Cattle (Bang's Disease), The Journal of Infectious Diseases, Volume Abortion in cattle occurs during all seasons, but because of the time of year most beef cows are bred, it is most frequent during the late winter and spring months. Actually, embryonic and fetal losses occur throughout the gestation period, but the term abortion usually is used only when the fetus is large enough to be found.

    Non-infectious abortion: causing abortion if cows ingest large amounts or fetal abnormalities with lesser amounts. (pomona) or 12 (hardjo) weeks earlier. Hardjo infection is associated with infertility (early embryonic death (EED)) and abortion (4 months to term), while pomona infection is associated with abortion during the last. early embryonic death and infertility,or IBR infection can result in late­term abortion (five to nine months of gestation).Cows aborting due to an IBR infection may experience temporary infertility from vaginitis after the inated herds are at the highest risk for IBR abortion problems.

Infectious infertility and abortion in cattle Farmnote 48/ By David Forshaw, Veterinary Pathologist, Animal Health Laboratories, Albany There are a number of infectious causes of abortion in cattle present in Western Australia however bovine brucellosis was eradicated from Western Australia in Campylobacteriosis and trichomoniasis.

Infertility has been linked to numerous factors in higher producing dairy cattle. Although infectious agents affect fertility, many non-infectious factors cause infertility in dairy cows. A later epidemiological study of 1, cows in 26 herds with abortion problems found a causal relationship between use of an early modified live IBR vaccine and abortion and infertility.

The authors reported that cows vaccinated as adults with modified live vaccine prior to breeding had a % abortion rate, pregnant cows in contact with. Infectious causes of reproductive failure in cattle are important in Australia and New Zealand, where strict biosecurity protocols are in place to prevent the introduction and spread of new diseases.

Neospora caninum ranks highly as an important cause of reproductive wastage along with fungal and bacterial infections.

Infectious bovine rhinotracheitis (IBR) is a major cause of viral abortion in the world, with abortion rates of 5%–60% in nonvaccinated herds. The virus is widespread, causes latent infections, and can recrudesce; therefore, any cow with a positive IBR titer is a possible carrier.

Rarely the Q fever organism will cause abortion in cows, sheep and goats. This disease is significant because it can cause serious illness in people. Cause a bacterial infection (Coxiella burnetii). There are also many non-infectious factors that contribute to infertility and reproductive loss.

Low calving rates may be due to infertility (failure of cows to conceive) or to early embryonic losses, abortion and stillbirth. This Agfact will focus on calf losses rather than the failure to become pregnant. Just what constitutes low calving.

This article examines problem areas related to anestrus, repeat breeding, pregnancy loss, and postpartum disorders. Mycoplasma bovigenitalium, Haemophilus somnus, ureaplasma, and the bovine herpes viruses, infectious bovine rhinotracheitis (IBR. Vibriosis is a venereal disease causing infertility and, occasionally, abortion.

It is caused by the bacterium Campylobacter fetus, which lives in the crevices of a bull’s prepuce (foreskin), but usually does not become established in the bull until it is about 4 years old or older.

This publication addresses several infectious causes of infertility and abortion in sows along with some preventive measures. Bacterial infections. Bacteria gain access to the uterus through the open cervix at farrowing, but usually are eliminated before they are able to establish an infection.

Sows will have a vaginal discharge for 1 to 3 days. Abortion in cattle By AbdEl-Sabour Trichomoniasis • The cause is Trichomonas fetus, (flagallated protozoan, very fragile and does not last long outside the reproductive tracts of cattle, killed rapidly by drying, excessive heat and antiseptic.

Infectious and Toxic Causes of Infertility in Cattle Leptospirosis There are several serovars of leptospirosis that can infect cattle, but the most important serovar in the United States in cattle is hardjo-bovis. This serovar is host-adapted to cattle, meaning some cattle remain infected and become carriers.

Abortion among dairy cows is one of the major causes of economic losses in the cattle industry. Abortions may be idiopathic or the result of metabolic or hormonal abnormalities, nutritional deficiencies, trauma, toxicities, or infectious agents.

There are multiple possible causes of both infertility and abortion in ewes, but making a definitive diagnosis is often difficult. Some diseases which are exotic to Australia can cause abortions. This webpage addresses why it is important to investigate causes of infertility and abortion, some common causes and the most effective approach to making a diagnosis.

Ureaplasm diversum and Mycoplasma bovigenitalium are generally thought to be relatively uncommon causes of abortions, although Ureaplasm can cause an outbreak of abortions if it is introduced into a ‘clean’ herd. These organisms have also been implicated as infectious causes of infertility.

However, it is often difficult to determine if one of these agents is the cause of an abortion .Infertility in the cow due to functional and management deficiencies The metritis complex in cattle Specific infectious diseases causing infertility and subfertility in cattle Veterinary control of herd fertility in intensively-managed dairy herds Veterinary control of .CONTAGIOUS ABORTION OF CATTLE1 Contagious abortion, abortion disease, or slinking of the calf, is a disease of the first importance wherever cattle raising is an important industry.

Its contagiousness was recognized by Europeans early in the eighteenth century, but the true nature of the disease remained a mystery until the development of the science of bacteriology made it possible for.
