Calf to Heifer: Rearing Young Stock as a Second Income

Every female calf born on your farm is either a future high-value animal or a future expense — and the difference is decided in the first two years, mostly by feeding and deworming that cost little. A well-reared heifer calves by about 24–30 months (cattle) and starts paying; a neglected one calves at four years or more, having eaten the difference. Whether you keep her or sell her, rearing done properly is one of the most reliable second incomes on a dairy farm.

The Economics in One Paragraph

A poorly grown heifer is not cheaper — she eats for extra unproductive years, which is the largest hidden cost on most smallholdings. A well-grown pregnant heifer, on the other hand, is one of the most saleable animals in any cattle market. Either way, the money is made or lost in daily growth, and daily growth is made in four stages.

Stage 1: The First Day (Colostrum)

Feed colostrum within the first hours of life — quantity, quality and speed decide immunity for months. This one habit prevents most calf scours and pneumonia. Full details in our colostrum management guide.

Stage 2: Milk Feeding to Weaning (0–3 Months)

• Feed milk at roughly one-tenth of body weight daily, split into two feeds, from clean utensils.
• Offer a palatable calf starter and soft green fodder from 2–3 weeks so the rumen develops — early solid feed is what allows safe weaning around 3 months.
• Watch dung daily; scours kill more calves than anything else — our guide on calf scours covers prevention and first response.

Stage 3: Growing Heifer (3–12 Months)

• Deworm on a schedule from the first weeks — wormy calves simply do not grow, whatever you feed. See why deworming matters.
• Feed good fodder plus about 1–1.5 kg of concentrate daily with a mineral mixture — skeleton and frame are built now.
• Where appetite and growth lag despite decent feeding, many farmers add an appetite and growth supplement such as Cattle Remedies Grazup during the growing phase.
• Vaccinate as your vet advises (FMD, HS/BQ, brucellosis for female calves at the recommended age).

Stage 4: Breeding Age

Breed on size, not birthdays: cattle heifers at roughly 250–300 kg (about 60% of adult weight) and buffalo heifers correspondingly — usually 18–24 months in well-grown crossbreds, later in buffaloes. Check body condition before service (our BCS guide shows how) and keep minerals daily — delayed puberty is very often a feeding and mineral problem, not bad luck.

FAQ

At what age should a heifer first calve?

Around 24–30 months for well-grown cattle heifers; buffaloes typically later. Every extra year of age at first calving is a year of feeding with no return — growth rate, not the calendar, is what brings the date closer.

Is it profitable to rear extra heifer calves for sale?

If you have fodder capacity, yes — pregnant, well-grown heifers of good parentage sell readily. The margin comes from cheap home-grown fodder, on-time deworming and steady growth; bought feed for a slow-growing animal eats the profit.

What about male calves?

Be honest about capacity: a male calf kept without purpose consumes fodder a growing heifer needs. Options vary by region — bullock demand, sale, or gaushala — but decide early instead of feeding by default.
