Livestock Herd Register (cattle, buffalo, goats, sheep, pigs)

About the Livestock Herd Register (cattle, buffalo, goats, sheep, pigs)

A register for a herd or flock that runs in your browser and keeps everything on your own device. Add each animal — cattle, buffalo, goats, sheep or pigs — with its tag, its official ear-tag number if it has one, breed, birth date, dam and sire, and where it came from. Record heats, inseminations (with the semen code) or natural services, pregnancy checks, births and drying off: the register shows when each animal should be checked, dried off and give birth, when a heat is expected, her interval between births and her days open.

Write each animal’s milk at each milking on one sheet; the register keeps each lactation, the 7-day average and the best day. A vaccination and deworming log follows schedule templates that name their source, with the products, batch numbers and doses written as you gave them, and reminders for your calendar. Income and expenses — for one animal, a group or the whole herd — give each animal’s account and the herd’s profit. In the free preview, history cards, QR ear-tag labels and herd reports show as marked page images; a Pro pass gives the clean documents.

Common uses

• A dairy farmer who wants every cow’s and buffalo’s calving, dry-off and pregnancy-check dates in one list, and a message to the AI technician when one is in heat.
• Keeping each animal’s vaccinations, deworming and treatments with batch numbers and withdrawal dates, for the veterinarian or a buyer who asks.
• Knowing which animals pay their way: milk at your own value, purchase and sale, their own costs and their share of the herd’s feed and labour.
• A goat, sheep or pig farm tracking kidding, lambing or farrowing dates, the young born and the animals sold.

How the breeding dates are worked out

• Expected birth = the last insemination or service + the gestation you set for the species, or the date the veterinarian gave at a positive pregnancy check. Dry off = the expected calving − the dry period, while she is in milk. Pregnancy check = the service + the days you set.
• A heat is expected one cycle after the last heat or service; after a service, the register watches for a return to heat one cycle later. A heat after the service, or a negative check, makes her open again.
• Interval between births = the days from one birth to the next; days open = the days from giving birth to the service she conceived from.
• The defaults are yours to change. Cattle and buffalo: heat every 21 days (18–24), the pregnancy check 60 days after insemination and about 60 days dry (NDDB, Handbook of Good Dairy Husbandry Practices); their gestation varies with the breed, so type it from your veterinarian or breed society. Goats: heat every 21 days on average and 145–155 days’ gestation, 150 on average (Merck Veterinary Manual). Sheep: heat every 16–17 days (Merck Veterinary Manual) and 142 to over 150 days’ gestation (TNAU Agritech Portal), of which 147 is used. Pigs: heat every 21 ± 1 days and 115–116 ± 1 days’ gestation (Merck Veterinary Manual).

Vaccination and deworming schedules

• Three templates come with their sources: the NDDB Dairy Knowledge Portal’s vaccination schedule for cattle and buffaloes (FMD, HS, BQ, brucellosis, theileriosis, anthrax), its deworming of calves, adults and cows after calving, and the TNAU Agritech Portal’s goat schedule. Choose the ones each species follows, mark the items not given on your farm, or copy one and edit it to your veterinarian’s schedule.
• The due dates follow each animal’s age, its last dose and its last birth. For an animal whose birth date is not known, an item given from an age onwards shows as due now, while one given only to young animals (brucellosis at 4–8 months, the deworming of calves and kids) waits until you type the birth date or record a dose. The due list puts every animal an item is due for on one line, so one entry records it for all of them; Reminders (.ics) puts what is coming into Google Calendar, Apple Calendar or Outlook.
• The log records what was given as you write it: the product and its batch number, how it was given, the dose as written on the label or by your veterinarian, and the milk and meat withdrawal dates you were told. The register never suggests a medicine or a dose.

Milk records

• The milk sheet lists the animals in milk — those that gave birth and are not dried off — for the day and milking you choose (morning, evening or a third milking). An animal under a milk withdrawal is marked on the sheet.
• Each animal’s lactation total, its average a day over the last 7 days and its best day follow, with the herd’s milk by day and month. A blank milk sheet can be printed for the shed, and yields can be brought in from a spreadsheet.

Each animal’s account and the herd’s profit

• Expenses and income are written for one animal, for a group (milking, dry, young stock, a shed) or for the whole herd. The whole herd’s expense is shared equally by the animals in the herd on its date, and a group’s by the animals of that group that were in the herd on its date (as the animals are grouped now: an animal moved to another group takes its share of the new group’s costs with it); animals bought and sold are counted from their own records.
• An animal’s account = its sale and its own income − its purchase and its own expenses − its share of the shared expenses + its milk at the value you set under Settings (if you set one).
• The herd’s account for a month, a year or everything shows its income and expenses by head and the profit. Every price is yours: the register has no market rates.

History cards, QR labels and ear-tag numbers

• An animal’s history card (A4, A5, US Letter or a phone picture) has its details, breeding record, young, milk, health record, what is due and its account, with a QR code. QR labels print on common label sheets (A4 with 21, 14 or 8 labels; US Letter with 14 or 10); their code holds plain text — the tag, ID, breed, birth date and your farm’s name and phone — that any phone camera reads. Headings can carry Hindi, Marathi, Gujarati, Punjabi, Telugu or Kannada beside the English.
• In India, ear tags carry a 12-digit number unique across the country that the Bharat Pashudhan application records (NDDB, Handbook of Good Dairy Husbandry Practices, on the Dairy Knowledge Portal). With the India setting the register checks that the number has 12 digits and is not on another animal; elsewhere, choose “Another ID” under Settings and name it.

Your data stays on this device

• Animals, breeding, milk, health and money records are kept in this browser on this device (IndexedDB). Nothing is uploaded, and you don’t need an account.
• Set a passcode under Data & backup to keep the register encrypted (AES-256) and locked when you step away.
• Clearing the browser’s site data deletes the register: make an encrypted backup regularly (the register reminds you) and restore it on another device to move the herd there. Your own data also comes out as CSV files.
• The message to the AI technician opens WhatsApp or your SMS app with the text filled in, one message at a time, for you to send from your own phone.

A privacy notice (India)

Under India’s Digital Personal Data Protection Act, 2023 a farm that keeps the names and phone numbers of the people it buys animals from, sells to, or who treat its animals is the Data Fiduciary for them, and section 5 asks for a notice when consent is requested. Rule 3 of the DPDP Rules, 2025 asks for an itemised description in clear and plain language. The template under Settings → Privacy notice is filled in with your farm and contact. It is a starting point, not legal advice: have a lawyer review it.

Limitations

• One device: the register does not sync between devices. Two tabs on the same device share it safely; to move to another device, restore an encrypted backup there.
• Yields, weights and events are typed in: it does not read milk meters, scales, RFID readers or the Bharat Pashudhan application.
• The gestation of cattle and buffalo is not filled in for you: it varies with the breed, so type your own under Settings.
• It records vaccinations, deworming and treatments as you write them and does not suggest or check any medicine, dose or withdrawal period.
• Screens are in English; documents can add headings in six Indian languages.

Privacy

Animals, breeding, milk, health and money records are kept in this browser on this device and never uploaded. Documents go only to the printer or file you choose, and messages to the AI technician are sent from your own phone.
