In ruminants, choline is an essential nutrient vital for fat metabolism and liver health, especially during the transition period of lactation. It is necessary for the liver to produce very low-density lipoproteins (VLDL), which transport fats out of the liver, preventing their accumulation as triacylglycerols. Without adequate choline, the liver can accumulate excess fat, leading to fatty liver syndrome, and overproduce ketones, leading to ketosis, a costly metabolic disorder. Choline is particularly important during the transition period when cows experience negative energy balance and mobilization of body fats, making them susceptible to metabolic diseases. Adequate choline availability also improves the efficiency of lipid metabolism, which directly impacts milk yield and overall milk production in dairy cows. Supplementation can lead to a reduction in metabolic diseases like fatty liver and ketosis, improving the cow’s overall health and well-being.

Why is Choline Important in Dairy Cattle?

Fat mobilization and liver health

Choline is a methyl donor and part of phosphatidylcholine, required for very low-density lipoprotein (VLDL) assembly and export. This assists in mobilizing non-esterified fatty acids from exiting the liver as triglycerides, reducing the threat of fatty liver and clinical/subclinical ketosis in early lactation.

Transition Period Nutrition

Dairy cows experience stress during the transition period because of the negative energy balance. Consequently, the body fats are mobilized to provide sufficient energy to the body. The body fats must be converted into VLDL in the liver to be utilized as a source of energy by the various tissues of the body. Choline supplementation during this period maximizes VLDL packaging in the liver.

Composition and yield of milk:

Feeding a choline-rich diet to cows at parturition enhances milk yield and occasionally fat and energy-corrected milk, especially in cows facing extreme negative energy balance. Response size is inconsistent and dependent on parity, body condition, and feed.

Reproduction & overall metabolism:

Through its promotion of liver health and methylation potential, choline could assist overall metabolic resistance during the transition period, which can indirectly enhance reproductive performance and health.

Limitations of Using Choline Chloride:

Pure synthetic choline chloride is hygroscopic in nature, which leads to storage instability. It can be metabolized by gut microbes into trimethylamine (TMA), a potentially harmful compound. Phytogenic choline can replace synthetic choline chloride, which varies in how well it protects choline in the rumen and delivers it where needed.

Choline stability in plants:

In plants, choline is a component of complex, lipid-bound molecules, primarily phosphatidylcholine. Since it is not in a free form, a greater proportion of the choline in whole, unprocessed, plant-based solution can bypass the rumen and reach the small intestine, where it can be digested and absorbed.

Vincholine

Vincholine, predominantly in the form of phosphatidylcholine, offers a superior alternative. Besides being phytobiotic, it offers secondary metabolites with different liver health-enhancing properties. Vincholine has intrinsic bioactivities on liver physiology, metabolism, and ensures maximum bioavailability. Phosphatidylcholine bypasses several ATP-dependent conversion steps, reducing energy expenditure and ensuring more effective cellular utilization. By minimizing oxidative losses, avoiding toxic metabolite formation, and improving nutrient efficiency, Vincholine supplementation supports better liver health, reproductive performance, and milk production. It plays a crucial role in dairy cattle, particularly during the transition period (around calving) and lactation.

Benefits

• Increases milk yield
• Supports milk production and milk fat synthesis
• Supports fat metabolism
• Reduces the risk of fatty liver syndrome
• Reduces metabolic disorders

In recent years, the incidence of diarrhea in calves has been steadily increasing, becoming a major challenge for cattle farmers worldwide. Among the various causes, parasitic illnesses such as Cryptosporidiosis are less well-known. Cryptosporidiosis in calves is mainly caused by a protozoan parasite, Cryptosporidium parvum, which affects the gastrointestinal tract and leads to diarrhea in calves. Transmission occurs via the faecal-oral route, through the ingestion of cryptosporidium oocysts present in contaminated water or food, or by direct contact with infected animals. It makes farm hygiene a critical control point. The economic losses associated with cryptosporidiosis in calves include the cost of treatment and management, reduced feed conversion and production efficiency, and losses due to mortality. Thus, effective cryptosporidium management in livestock has become necessary. Calf disease prevention using good biosecurity measures, like sanitary practices and managing exposure risks, are important for preventing this infection.

Pathogenesis of Cryptosporidium spp.:

Key Strategies for Maintaining Strict Hygiene and Sanitation in Livestock:

Cleaning and Disinfection

·      Work under the assumption of the “all-in/all-out” principle in managing calves, so thorough cleaning and preferably drying for several weeks must occur between batches of calves.

·      Control pests such as rats, mice, and flies. Rodents and pets should not be allowed to enter areas where calf feed or milk are stored.

·      Maintain clean, dry housing with raised feed and water troughs to minimize contamination from the environment.

·      Use steam cleaning between batches of animals. Steam cleaning is recommended because oocysts are inactivated at temperatures above 60°C. Also, C. parvum oocysts can survive at -20°C, especially in the presence of a cryoprotectant.

Pasture Management

·      Give special attention to grazing lands because they help reduce the environmental parasite load.

·      Realize that the largest portion of the parasite life cycle occurs outside the animal.

·      Choose pasture techniques that reduce parasite levels and chemical dewormers.

·      Keep the grass in a vegetative stage so that it maintains height and good nutrition for calves, thereby accustoming them to the strength to fight infections.

Water and Feed Management

·      Provide clean and fresh water from an uncontaminated source.

·      Avoid stagnant water sources.

·      Sanitised or cleaned feed and water troughs should be used to minimise the possibility of contamination.

Since the disease has no highly efficient calf diarrhea drug treatment yet, hygienic and sanitary conditions undergo the major prophylaxis methods against cryptosporidiosis. Along with this, natural calf health solutions, such as plant extracts, can offer complementary preventive measures in improving animals’ gut health. Effective prevention supports the maintenance of a healthy gut microbiome, limiting the colonization and impact of potential pathogens and protozoa. This will contribute to the overall health and productivity of the herd.

CRYPTORID

Cryptorid is specially formulated for the management of calf diarrhea. It is a non-antibiotic, plant-based solution designed to prevent bacterial scours and disrupt the lifecycle of Cryptosporidium, which reduces the risk of cryptosporidiosis in calves. It contains a blend of plant extracts rich in phenolic compounds, including tannins, flavonoids, isoflavones, and phenolic acids, which work synergistically to enhance calf performance, support gut health, and effectively control diarrhea.

BENEFITS

1. Disrupts the lifecycle of Cryptosporidium
2. Reduces oocyst shedding
3. Boosts immunity in juveniles
4. Strengthens and protects the villous lining of the intestinal epithelium
5. Antioxidant and Anti-inflammatory properties to strengthen the defense system
