Introduction

The economic impact of neonatal disease in calves has been acknowledged for many years. Postmortem and bacteriological analyses of these calves reveal numerous reasons for this loss, with colibacillosis caused by Escherichia coli being the most prevalent. It is estimated that a mortality rate of 20 percent in calves can lead to a 60% reduction in the net profit of a business. Neonatal calves are vulnerable to various diseases; effective management can help prevent avoidable deaths. Diseases in calves significantly affect the financial viability of cattle operations because of the immediate costs associated with calf losses and treatment, as well as the long-term repercussions on their performance. &nbsp

Diarrhea (scour)   

Diarrhea is the primary health concern for young calves and milk-fed animals, resulting from changes in gut function and microbiota that increase the volume of manure and fluids expelled by calves.

It is typically the leading cause of illness and death in pre-weaned calves, responsible for as much as 50% of mortality in this group.

There are two categories: Nutritional and infectious.

Nutritional diarrhea often stems from stress due to lapses in management routines (such as insufficient colostrum intake).

Nutritional diarrhea frequently develops into infectious diarrhea, resulting from a high level of pathogens. Various infectious agents may lead to diarrhea in calves, and it is common for multiple agents to be involved, including bovine rotavirus group A, bovine coronavirus, Salmonella spp., Clostridium perfringens type C, Escherichia coli and Cryptosporidium parvum.

According to NAHMS (2007), 19% of calves experience a failure in the passive transfer of immunoglobulin, and 24% suffer from diarrhea within their first month. The most prevalent clinical manifestations of calf illnesses resulting from inadequate colostrum intake are septicemia and diarrhea. (Pavlata et al. 2004)

Signs of scour  

• Easy to identify, characterized by an increase in the frequency and volume of calf manure, with higher water content than usual.
• Faeces appearing bright yellow or white.
• Cows showing signs of depression and displaying a lack of interest in feeding.
• Cows exhibiting sunken eyes and/or an elevated body temperature.
• Skin that remains peaked or tented when lifted, which indicates dehydration.
• Loss of weight and general weakness.
• In extreme cases, calves may collapse, enter a comatose state, and die.

Research indicates notable alterations in the bacterial populations of the gut microbiota during episodes of diarrhea when compared to what is regarded as a “healthy” or “balanced” microbiota.

Assessment of hydration levels in calves experiencing diarrhea.

 Anticipating indications:  

• Dry snout, dense mucus emerging from the nostrils.
• Extremely solid feces.
• Rejection of milk.
• Inclination to recline.
• An elevated body temperature (above 39.5°C).

Nutritional Control of Dehydration

Replace lost fluids and electrolytes as soon as possible (2-4 liters of electrolyte solution each day, in addition to regular feeding).

Homemade electrolyte solution recipe (For 1 liter of warm water)

Glucose – 5 teaspoons Sodium bicarbonate – 1 teaspoon Table salt – 1 teaspoon (Note: 1 teaspoon is approximately 5 grams) * Use glucose instead of table sugar (sucrose).

Nutritional Treatment of Diarrhea

Isolation  

• Calves experiencing scours should be kept in a clean, dry, and warm pen away from others.

Rehydration therapy  

• It’s essential to provide adequate liquids and electrolytes to compensate for the losses.
• Offering frequent, smaller amounts of electrolytes or milk is more effective than giving   larger quantities less often.
• Healthy calves require four liters of fluid daily, while scouring calves need an additional four liters to make up for lost fluids.
• Electrolyte treatments for scours should have a Strong Ion Difference (SID) of 60mmol.

 Milk Feeding  

• Continuing to provide milk or a high-quality milk replacer supports intestinal healing.
• Allow calves to drink milk or milk replacer as long as they desire.

Due to the natural antimicrobial components of fresh milk (such as lactoferrin, lactoperoxidase, lysozyme, etc.) and its excellent digestibility, milk serves as an ideal nutritional aid for calves with diarrhea.

• Milk should never be mixed with electrolyte solutions, as this can interfere with proper milk clotting.
• Electrolytes should be administered at least 30 minutes prior to a milk feed.
• Milk or milk replacer should not be delivered via stomach tubing.
• Antibiotics should only be given through injection when the calf appears very ill or has an elevated temperature.

Other  

Supplementing with Prebiotics, Probiotics, and Synbiotics   

The use of prebiotics, probiotics, and synbiotics has been suggested as a strategy to address dysbiosis by reestablishing microbial diversity and modifying the disrupted intestinal microbiota in various digestive conditions, including diarrhea, irritable bowel syndrome, inflammatory bowel disease, and ulcerative colitis in calves. Prebiotics comprise non-digestible components that encourage the growth of beneficial microorganisms and help safeguard the gut against potentially harmful pathogens. In neonates, probiotics support the development of the digestive and immune systems by enhancing microbial diversity and increasing species richness.

Colostrum Supplementation    

Proper delivery of high-quality and adequate amounts of colostrum to newborn calves reduces the likelihood of diarrhea during the initial weeks of the calf’s life. The significance of effective colostrum management in achieving sufficient passive transfer is clear in preventing neonatal calf diarrhea (NCD).

Fecal Microbiota Transplantation (FMT)  

Fecal microbiota transplantation (FMT) involves the placement of fecal matter from a healthy donor into the intestines of the recipient to directly alter the gastrointestinal microbiota of the recipient.

Miscellaneous

• Zinc serves as a potent anti-diarrheal agent.
• Ascorbic acid supplementation.
• Administer probiotics that contain bacteria capable of producing lactic acid.
• Ensure sufficient colostrum is provided within the first hours post-birth.
• Offer appropriate housing or shelter to protect from environmental stressors.
• Design sheds thoughtfully to prevent overcrowding.
• Avoid mixing calves of different ages (e.g., newborns with calves older than 3-4 days) since younger calves are more vulnerable.
• Reduce stress through consistent management practices, such as disbudding and castration.
• Uphold strict hygiene standards by cleaning and disinfecting feeding tools and facilities.
• Prevent the accumulation of fecal matter around feed and water troughs.
• Elevate feeding and water troughs to a minimum height of 0.75m above the ground.
• Yeast from Saccharomyces cerevisiae (SCY).

Conclusion  

Effective nutrition management plays a critical role in the recovery and overall health of neonatal calves suffering from diarrhea. Providing proper hydration through electrolytes, coupled with high-quality milk or milk replacers, ensures essential nutrient replenishment and supports the immune system. Early intervention, along with appropriate feeding protocols, can help reduce the severity and duration of diarrhea, minimize the risk of dehydration, and promote a faster recovery. Ongoing monitoring and adapting nutritional strategies to individual calf needs are key to improving outcomes and ensuring long-term health. With a well-balanced approach, dairy farmers can significantly reduce the impact of neonatal diarrhea, ultimately leading to healthier, more productive calves.
