Abortion in cattle is a significant issue in livestock production, with considerable economic and reproductive impacts. Various factors can trigger pregnancy loss, including infectious agents, nutritional deficiencies, inadequate management, and adverse environmental conditions (Peter, 2013). Among these, nutrition plays a fundamental role in preventing abortions and ensuring fetal viability. This article explores the main causes of abortion and how a balanced diet can help reduce this issue.

Main Causes of Abortion in Cattle

Abortions can be classified into infectious and non-infectious causes:

1. Infectious Causes

Infectious diseases are among the leading causes of abortions in cattle and are often associated with pathogens that affect the placenta and fetus (Grooms, 2006). Some of the most relevant agents include:

• Bovine Brucellosis (Brucella abortus): A zoonotic disease that causes abortions in the last third of pregnancy. It is mainly transmitted through contaminated reproductive secretions (Poester et al., 2013).
• Leptospirosis (Leptospira spp.): Causes abortions at any stage of pregnancy and spreads through water and soil contaminated with infected urine (Ellis, 2015).
• Neosporosis (Neospora caninum): A protozoan transmitted by dogs that infects cattle placentas, causing recurrent abortions, usually in the second trimester of pregnancy (Dubey et al., 2007).
• Bovine Viral Diarrhea (BVD) and Infectious Bovine Rhinotracheitis (IBR): Viruses that affect the placenta, leading to early embryonic loss, late-term abortions, or weak newborns (Grooms, 2006).

2. Non-Infectious Causes

• Nutritional deficiencies: Poor nutrition compromises embryo viability and pregnancy maintenance (Diskin & Morris, 2008).
• Heat stress: Prolonged exposure to high temperatures reduces progesterone levels, affecting embryo retention (Hansen, 2007).
• Toxins and abortifacient plants: Consuming contaminated forages with mycotoxins, such as Claviceps purpurea (ergotism), is linked to cattle abortions (Richard, 2007).

The Role of Nutrition in Abortion Prevention

Proper nutrition during pregnancy is crucial for fetal development, placental integrity, and abortion prevention. A well-balanced intake of energy, proteins, minerals, and vitamins is essential for a successful pregnancy.

1. Energy and Protein: A Necessary Balance

Energy deficiency reduces progesterone synthesis, a key hormone for pregnancy maintenance. Studies have shown that cows with an energy deficit in the first 30 days post-insemination have a higher risk of embryonic loss (Butler, 2000). Conversely, excessive energy intake can lead to fat accumulation in the liver, impairing liver function and hormone production (Drackley, 1999).

Regarding protein, inadequate levels can compromise the synthesis of placental growth factors, affecting fetal viability (Green et al., 2012).

2. Essential Minerals

Minerals play key roles in bovine reproduction:

• Calcium (Ca) and Phosphorus (P): Essential for fetal bone development and uterine muscle contractions during labor (Roche et al., 2013).
• Magnesium (Mg): Its deficiency can induce metabolic stress and increase abortion incidence (Suttle, 2010).
• Copper (Cu), Zinc (Zn), and Selenium (Se): Strengthen the immune system and protect against infection-induced abortions (Harrison et al., 1984).
• Iodine (I): Essential for fetal thyroid function, preventing weak births or abortions (Hostetler et al., 2003).

3. Vitamins: Fetal Viability Regulators

Vitamins play a crucial role in reproduction:

• Vitamin A: Contributes to embryonic and placental development (Pate, 2004).
• Vitamin E and Selenium: Reduce oxidative stress and protect against bacterial infection-related abortions (Weiss et al., 2002).
• Vitamin D: Essential for calcium metabolism, reducing the risk of dystocia and late-term abortions (Littledike & Goff, 1987).

4. Nutritional Management in Pregnant Cows

• Avoid sudden dietary changes, especially in the last third of pregnancy.
• Ensure access to high-quality forages, avoiding contaminants like mycotoxins and fungi.
• Use strategic supplementation during critical periods, such as forage shortages in winter or droughts.
• Guarantee access to clean, uncontaminated water, as dehydration can induce fetal stress.

Reproductive Management and Abortion Prevention

Besides nutrition, implementing appropriate reproductive strategies is essential for preventing abortions:

1. Bull selection and evaluation: Bulls with poor semen quality can increase early embryonic mortality rates (Kastelic, 2013).
2. Well-designed artificial insemination and synchronization protocols: Ensure efficient fertilization and reduce the risk of embryonic loss (Patterson et al., 2004).
3. Use of ultrasound for pregnancy monitoring: Allows early detection of non-viable embryos and facilitates reproductive decisions (Fricke, 2002).
4. Selection and management of embryo recipient cows: Proper nutritional and health status of the recipient improves pregnancy rates (Mapletoft et al., 2003).

Conclusion

Preventing abortions in cattle requires an integrated strategy that includes health management, reproductive planning, and, most importantly, proper nutrition. A balanced diet, combined with disease control and the implementation of good reproductive practices, is key to minimizing pregnancy loss and improving productive efficiency. Investing in adequate nutrition and continuous herd monitoring not only reduces abortion incidence but also enhances livestock profitability.

Freemartinism is a reproductive condition that occurs in female cattle born as twins to a male. It is a genetic and physiological anomaly that disrupts the normal development of the female’s reproductive organs, rendering her infertile in most cases. This phenomenon significantly impacts reproduction and herd management, making it essential to understand and identify.

How Does Freemartinism Occur?

During twin pregnancies, when one fetus is male, and the other is female, both share the same placenta. This results in a blood exchange between the two fetuses due to shared vascular connections. Consequently, male hormones (androgens) and cells from the male fetus reach the female fetus, altering the development of her reproductive system.

The exposure of the female to male hormones during critical stages of embryonic development causes partial or complete masculinization of her reproductive organs, leading to infertility. The male twin, on the other hand, is usually born without complications.

Characteristics of Freemartinism

Freemartin cattle typically exhibit the following characteristics:

• Underdeveloped reproductive organs: Ovaries may be small or absent, and the uterus is often incomplete.
• Infertility: Most freemartin females are unable to reproduce.
• Masculine traits: Some display physical characteristics or behaviors associated with males.

In many cases, freemartin heifers appear normal at first glance, but their condition becomes evident when they fail to show heat or cannot conceive.

Diagnosing Freemartinism

To confirm whether a twin female is a freemartin, the following techniques can be used:

1. Blood or DNA testing: Identifies the presence of male cells in the female.
2. Rectal palpation or ultrasound: To evaluate the development of reproductive organs.
3. Physical examination: Some freemartin females may have visible anomalies in their external reproductive anatomy.

Impact on Livestock Production

Freemartinism represents an economic loss for producers, as these females cannot be used for reproduction. Therefore, it is crucial to identify them early and repurpose them for other uses, such as fattening or sale.

Conclusion

Freemartinism is an intriguing yet challenging phenomenon in bovine reproduction. If you suspect freemartin females in your herd, early diagnosis is key to effective management.

Proper nutrition plays a fundamental role in maximizing the reproductive potential of cattle. Whether you manage beef or dairy herds, understanding the connection between diet and reproductive performance is crucial for improving pregnancy rates, herd health, and overall productivity.

Key Nutritional Factors Influencing Reproduction

1. Body Condition Score (BCS)

A cow’s body condition score (BCS) is a visual indicator of its energy reserves.

• Underweight cattle: Low BCS can lead to irregular estrous cycles and low fertility.
• Overweight cattle: Excessive body fat may interfere with hormonal balance, decreasing conception rates. Maintaining an ideal BCS (between 5 and 7 on a 9-point scale) supports optimal reproductive performance.

2. Energy and Protein Balance

• Energy: Adequate energy intake ensures cows cycle regularly and produce viable embryos. Energy deficiencies can delay the onset of estrus or cause early embryonic losses.
• Protein: High-quality protein is vital for follicular development and maintaining a healthy uterine environment. However, excess dietary protein may reduce conception rates due to altered uterine pH.

3. Micronutrients and Minerals

Micronutrients play a pivotal role in supporting hormonal function and reproductive health:

• Phosphorus and Calcium: Crucial for skeletal and metabolic functions, these minerals also influence ovulation and fertility.
• Selenium and Vitamin E: Reduce oxidative stress, improving conception rates and fetal health.
• Zinc: Essential for hormone production and maintaining uterine health.

4. Fats and Omega-3 Fatty Acids

Dietary fats, particularly omega-3 and omega-6 fatty acids, improve energy density in feed and positively influence reproductive performance by enhancing ovulation and early embryo survival.

---

Impact of Poor Nutrition on Reproduction

• Delayed puberty in heifers: Insufficient nutrients during development lead to late maturation.
• Anestrus: Nutritional stress can cause cows to stop cycling, reducing herd pregnancy rates.
• Low conception rates: Deficiencies or imbalances in key nutrients lower fertilization and embryo viability.

Embryo transfer in cattle has emerged as a revolutionary technique in animal reproduction, offering various economic advantages for livestock producers. This procedure, which involves the manipulation of embryos in vitro and their subsequent introduction into recipient females, has transformed the livestock industry by providing significant benefits in terms of efficiency and profitability. Embryo transfer in bovines has emerged as a revolutionary technique in reproduction animal, offering various economic advantages for livestock producers. This procedure, which involves the manipulation of embryos in vitro and their subsequent introduction into recipient females, has transformed the livestock industry by providing significant benefits in terms of efficiency and profitability.

Firstly, embryo transfer allows the superior genetics of elite bovines to be maximized. Producers can carefully select the best breeders, those with desirable genetic characteristics such as higher milk production, disease resistance and greater feed efficiency. By using this technology, it is possible to multiply the offspring of these elite animals, generating a herd with superior genetic characteristics. This not only improves the quality of the livestock, but also increases production and ultimately the farmer’s income.

Furthermore, embryo transfer speeds up the reproduction process. Instead of relying solely on natural reproduction, which is limited by the reproductive cycle of females and geographical limitations, this technique allows for a greater number of offspring in a shorter period of time. This means producers can increase the herd replacement rate and have more animals ready for production in less time, resulting in a more efficient and profitable production cycle.

Another key economic benefit lies in the possibility of exporting quality genetics. Embryo transfer allows livestock producers to share superior genetics with breeders around the world without having to ship live animals long distances. This not only reduces transportation costs and the risk of associated diseases, but also opens up new income opportunities through the sale of embryos and frozen semen internationally.

Additionally, embryo transfer offers precise control over the number of offspring of elite animals. While natural breeding can result in large litters with genetic variability, this technique allows for more selective and controlled breeding. Producers can plan and adjust their herd according to market demands, avoiding unwanted surpluses and maximizing resource efficiency.

Importantly, although the initial investment in technology and training can be significant, long-term costs can be substantially reduced with the continued implementation of embryo transfer. Genetic improvement and reproductive efficiency result in a more productive and resilient herd, which translates into higher income and a better competitive position in the livestock market.Economic advantages of embryo transfer in cattleEconomic advantages of embryo transfer in cattle

Vaginal prolapse in cattle is a condition that can occur during calving or in situations of physical stress. This phenomenon is characterized by the abnormal displacement of vaginal tissue outside the vulvar opening, and timely intervention is essential to ensure the health and well-being of the animals.

Causes of Vaginal Prolapse in Cattle:

Vaginal prolapse in cattle can have various causes, with calving being one of the most common. During the calving process, pressure on pelvic tissues can lead to the weakening of muscles supporting the reproductive organs. Additionally, the presence of dystocia, or difficulties in calving, can significantly increase the risk of prolapse.

Factors such as inadequate body condition, poor livestock management, or stress can contribute to pelvic floor weakness, exacerbating susceptibility to vaginal prolapse. It is crucial to understand the specific conditions surrounding each animal to effectively address this condition.

 

Symptoms and Diagnosis:

Symptoms of vaginal prolapse in cattle are evident and typically include the presence of visible vaginal tissue outside the vulva. Swelling and redness may also accompany this condition. Accurate diagnosis is achieved through a thorough clinical evaluation by a veterinarian, who will determine the severity of the prolapse and look for possible underlying causes.

 

Treatment:

Treatment of vaginal prolapse in cattle should be carried out by a veterinary professional. Firstly, a thorough cleaning of the prolapsed tissue is performed to prevent infections. Subsequently, lubrication is applied to facilitate the repositioning of the prolapse to its original position.

Repositioning the prolapse involves careful handling to avoid additional injuries. In some cases, sutures may be used to hold the tissue in place, and retention devices may be implemented to prevent recurrences. The use of medications, such as anti-inflammatories or antibiotics, may be recommended depending on the clinical situation.

 

Prevention:

Preventing vaginal prolapse in cattle involves implementing proper management practices. This includes maintaining optimal body condition in pregnant cows, providing safe calving facilities, and ensuring calm and stress-free handling. Additionally, close monitoring during calving can help identify and address any early signs of dystocia.

 

Nutritional Management:

Nutrition plays a crucial role in preventing vaginal prolapse. Ensuring a balanced diet, rich in essential nutrients, contributes to maintaining overall health and tissue strength. Consultation with a veterinary nutritionist can be beneficial in designing feeding plans that meet the specific needs of the livestock.

 

Potential Complications:

If not adequately addressed, vaginal prolapse in cattle can lead to serious complications. Continuous exposure of the tissue can result in infections, chronic inflammation, and, in extreme cases, necrosis. These complications can adversely affect the reproductive capacity of the cow and its overall well-being.

 

Importance of Veterinary Care:

Timely veterinary care is essential for the successful management of vaginal prolapse in cattle. Veterinary professionals have the necessary expertise to assess the severity of the prolapse, identify possible contributing factors, and apply appropriate treatment. Additionally, they provide guidance on preventive measures and management strategies to reduce the risk of recurrence.

In cattle, hernias are a common condition that can affect both calves and adult animals. There are several types of hernias in cattle, each with its distinctive characteristics. The most common types are described below:

1. Umbilical hernia: This is one of the most common hernias in calves. It occurs when the umbilical ring does not close properly after birth. As a result, a sac forms in the navel area that may contain fatty tissue or even part of the intestine. Umbilical hernias are usually visible near the belly button and can vary in size.

2. Inguinal hernia: These hernias are located in the animal’s groin and are more common in non-neutered males. They may contain a portion of the small intestine and, in more severe cases, the large intestine. Inguinal hernia is a condition that must be treated with surgery.

3. Scrotal hernia: Similar to the inguinal hernia, this hernia is located in the scrotum area and may contain intestine. It is often most obvious when the animal is standing.

4. Diaphragmatic hernia: Unlike previous hernias, this one affects the diaphragm, the muscle that separates the thorax from the abdomen. When the diaphragm weakens or ruptures, the abdominal organs can move into the thorax, which can be life-threatening for the animal. This is a serious condition that requires urgent veterinary attention.

5. Abdominal wall hernia: These hernias involve a tear or weakness in the abdominal wall, allowing internal organs to protrude. Abdominal wall hernias can be caused by traumatic injuries or congenital weaknesses in the abdominal muscles.

6. Pararectal hernia: They are less common and occur in the pelvic region. They may contain fatty tissue or even the animal’s rectum.

Treatment of hernias in cattle generally involves surgery to reposition and secure the herniated organs and repair the abdominal wall or diaphragm, as necessary. Prevention is essential, and farmers must be diligent in handling and caring for calves to reduce the risk of umbilical hernias. Additionally, early castration can prevent inguinal and scrotal hernias in males.
