Question 1

How many times can a cow get pregnant?

Accepted Answer

There is no fixed lifetime limit. Productive life depends on fertility, health, conformation, and culling policy. Many commercial dairy cows complete multiple lactations when managed well.

Question 2

How long is gestation in dairy cows?

Accepted Answer

Gestation averages about 280 days (roughly nine months). Breed, calf sex, and individual variation can shift timing by several days, so expected calving dates are planning windows rather than exact appointments.

Question 3

Can I sell milk while a cow is on antibiotics?

Accepted Answer

Not from that animal during the milk withdrawal period stated on the product label (or a longer period set by your veterinarian for extra-label use). Divert treated cows’ milk until withholding ends. Never rely on taste or appearance to judge residue safety.

Question 4

What is colostrum and why does timing matter?

Accepted Answer

Colostrum is the first milk after calving, rich in antibodies and nutrients. Calves should receive adequate colostrum as soon as practical after birth — commonly within the first few hours — according to your veterinary calf protocol.

Question 5

When should dairy calves be weaned?

Accepted Answer

Weaning age depends on health, starter intake, and farm protocol — often somewhere around 6–12 weeks in many systems, but your veterinarian and nutrition plan should set the target. Abrupt weaning of unhealthy calves increases setbacks.

Question 6

How often should dairy cows be milked?

Accepted Answer

Most commercial dairies milk two or three times per day. Three sessions are common where yields are high or market timing requires midday milk. Consistent intervals matter as much as the number of milkings.

Question 7

What is the dry period and how long should it be?

Accepted Answer

The dry period is the rest between lactations before the next calving. Many farms target about 45–60 days dry, adjusted for yield level, udder health, and veterinary advice. Too short or poorly managed dry periods can hurt the next lactation.

Question 8

What are open days?

Accepted Answer

Open days generally measure how long a cow remains non-pregnant after calving. Longer open days mean more feed cost without a pregnancy progressing toward the next lactation, so they are a key reproduction KPI.

Question 9

What is a voluntary waiting period (VWP)?

Accepted Answer

VWP is the planned delay after calving before you intentionally breed again — often about 45–60 days. It gives the uterus and metabolism time to recover before services begin.

Question 10

How long is a typical cow heat cycle?

Accepted Answer

The bovine estrous cycle usually lasts about 18–24 days, averaging near 21 days. Standing heat itself is much shorter, which is why scheduled heat detection matters.

Question 11

What is peak lactation?

Accepted Answer

Peak lactation is the period of highest daily milk yield after calving, often roughly 4–10 weeks into lactation depending on breed, parity, and nutrition. Failure to rise toward peak is an early warning for fresh-cow problems.

Question 12

Should I record milk by session or only as a daily total?

Accepted Answer

Prefer session recording (morning, afternoon, evening). Daily-only totals hide which milking failed and make cow rankings unfair when a session was missed. Session logs also reveal parlor and staffing issues.

Question 13

What body condition score should a cow have at calving?

Accepted Answer

Many dairy programs on a 1–5 scale aim near the middle (often about 3.0–3.5). Exact targets should be set with your nutritionist or veterinarian for your herd type and scale system.

Question 14

How does DairyLogs help dairy farm management?

Accepted Answer

DairyLogs connects operational records — milk sessions, breeding protocols, calving, health (including withhold and medicine stock), feed plans and today’s due feedings, inventory, finance (paid now or later), team payroll, and related workflows — so teams can act on dated animal history instead of notebook memory.

Question 15

How much does DairyLogs cost?

Accepted Answer

DairyLogs is free for herds of up to 10 animals. Paid plans are billed in US dollars: Starter $10/month ($100/year), Pro $15/month ($150/year), and Business $25/month ($250/year). Yearly billing includes two months free versus paying monthly for a year. Paid plans are activated after you message us on WhatsApp — there is no self-serve card checkout. Larger operations can request a custom quote.
