Effective new-born calf management is crucial for ensuring the health, survival, and long-term productivity of calves. Proper care, colostrum feeding, and hygiene practices significantly improve calf development. Below are the key steps for optimal new-born calf care.
Immediate Care After Birth
Clear Airways: Remove mucus from the calf's mouth and nose to ensure proper breathing.
Dry and Warm the Calf: Use a clean cloth or straw to dry the calf, preventing hypothermia.
Umbilical Cord Care: If needed, cut the umbilical cord and disinfect it with iodine or another antiseptic to reduce infection risk. Rapid drying of the umbilical cord is essential.
Colostrum Feeding: The Key to Immunity
Colostrum feeding is critical in the first hours of life to provide essential antibodies and nutrients.
A new-born calf should consume 2-4 litres of high-quality colostrum within the first 6 hours to build immunity. Continued colostrum feeding is necessary during the first 24 hours, as antibody absorption declines rapidly afterward.
Colostrum quality assessment is essential:
Brix Refractometer: A Brix value above 22% indicates high-quality colostrum.
Colostrometer: Measures colostrum density, with good-quality colostrum containing >50 mg/mL IgG and poor quality <20 mg/mL IgG.
New-born Calf Feeding: Milk Feeding Guidelines
After colostrum feeding, proper new-born calf feeding is essential for growth and development.
Daily Milk Intake: Feed 5-7 litres of fresh milk or milk replacer per day, split into 2-3 meals.
Milk Quality and Temperature: Ensure milk is clean, free from bacteria, and at an optimal feeding temperature of 38°C.
Pasteurization: If possible, pasteurize fresh milk to eliminate harmful pathogens.
Housing and Environmental Management
Providing a clean and comfortable environment is a vital part of new-born calf management.
Individual Pens: Keep calves in clean, disinfected individual pens at a temperature of 15-20°C.
Bedding: Use clean, dry straw, replacing it regularly. In cold weather (<12°C), consider calf jackets for warmth.
Temperature Control: In extreme cold, use heated rooms or heat lamps to help calves maintain body temperature.
Ventilation: Prevent drafts while maintaining good air circulation to reduce disease risk.
Disease Prevention and Hygiene
Monitor for Diarrhoea: Treat cases immediately with electrolytes and veterinary-approved supplements. Consult a veterinarian before administering antibiotics.
Isolation of Sick Calves: To prevent disease outbreaks, immediately separate sick calves into a dedicated isolation area.
Vaccination and Deworming: Work with a veterinarian to establish a preventive health program.
Transition to Solid Feed
To promote rumen development, introduce solid feed early in new-born calf feeding.
Start from the 2nd Week: Offer high-quality dry hay, feed concentrate, and fresh water.
Encourage Consumption: Provide small, fresh amounts of solid feed to stimulate intake.
Hygiene: Keep milk, water, and feed containers clean to prevent disease transmission.
Weaning: The Final Step in New-born Calf Management
Weaning is a gradual process that should be carefully managed.
Typically, calves are weaned at 2-3 months when they consume 1.5-2 kg of solid feed daily and have doubled their birth weight.
Gradual Reduction: Reduce milk intake step by step to ensure a smooth transition to solid feed.
Conclusion
Proper new-born calf management, including colostrum feeding, milk feeding, and disease prevention, ensures healthy growth, reduces mortality, and supports long-term productivity. Implementing these best practices lays a strong foundation for future breeding and fattening success.
