Murrah Buffalo Breeding Guide: From Heat Detection to Calving

Murrah Buffalo Breeding Guide

Breeding efficiency is the primary driver of profitability in a dairy farm. A buffalo that calves every 13-14 months is profitable; one that calves every 18-20 months is a loss-maker, regardless of how much milk she gives.

Murrah buffaloes are known for being seasonal breeders and often exhibit silent heat, making breeding management more challenging than in cows.

1. Understanding the Estrous Cycle

• Puberty: Murrah heifers typically reach puberty (first heat) at 24-30 months of age, or when they reach a body weight of 300-350 kg.
• Cycle Length: The estrous cycle repeats every 21 days (average range 18-24 days).
• Heat Duration: The heat period lasts for 12-24 hours.

2. Solving the "Silent Heat" Problem

The biggest challenge with buffaloes is that they do not always "bellow" or mount other animals like cows do. This is called Silent Heat, and missing it means losing 21 days of production.

Signs of Heat in Buffaloes:

• Use of Teaser Bull: The most effective method. A vasectomized bull introduced to the herd morning and evening will identify cows in heat.
• Frequent Micturition: The animal urinates frequently in small amounts.
• Vulvar Swelling: Slight swelling and reddening of the vulva (less pronounced than cows).
• Mucous Discharge: Clear, transparent, stringy mucous (robbing) hanging from the vulva (often seen early morning).
• Restlessness: Stops eating, looks agitated, or keeps tail raised.
• Drop in Milk: A sudden, unexplained drop in milk yield in a lactating animal.

3. Artificial Insemination (AI) Protocol

Timing is everything.

• The AM-PM Rule:
  • Heat observed in Morning -> Inseminate in Evening (same day).
  • Heat observed in Evening -> Inseminate in Morning (next day).
• Semen Selection: Use high-quality frozen semen from certified bulls (NDDB/State Boards) with a high dam yield record (progeny tested bulls preferred).

4. Pregnancy Diagnosis

Do not wait for the animal to not come back in heat.

• Get a rectal palpation done by a qualified vet by Day 60-90 post-insemination.
• Early confirmation helps you plan feeding and management; early negative detection allows you to treat for infertility immediately.

5. Care of the Pregnant Animal

Divided into trimesters. The last 3 months are crucial.

The Dry Period (Last 60 Days)

You MUST stop milking the animal 60 days before expected calving.

• Why? To allow mammary gland tissue to regenerate and the calf to grow (fetus gains 60% of weight in the last 2 months).
• Feeding: Increase concentrate feed. "Steaming up" (feeding extra grain) in the last 2 weeks helps prepare for lactation.
• Calcium: Restrict calcium slightly in the dry period to prime the body's calcium mobilization mechanism (preventing milk fever later).

6. Calving Management

• Signs: Udder engorgement, relaxation of pelvic ligaments, restlessness.
• Process: Normal delivery takes 30-60 minutes after the water bag appears.
• Separation: Move to a clean, straw-bedded calving pen 1 week prior.
• Assistance: Only assist if no progress is made after 1 hour of straining. Pull legs gently downwards (towards hocks) only when the animal strains.

7. Tackling Infertility (Anestrus)

If your buffalo isn't cycling:

• Deworming: Heavy worm load causes anemia and anestrus.
• Mineral Deficiency: Supplement with chelated minerals (Copper, Cobalt, Phosphorus).
• Hormonal Treatment: Consult a vet for hormonal protocols (like Ovsynch) only if nutrition is optimal.

Proper breeding management turns a "dairy farm" into a "dairy business".
