Odisha CHSE +2 VOC Dairy Farmer / Entrepreneur (AGD) cheat sheet

Dairy enterprise profit = milk sales + manure + calf/animal sales + value-added product sales − feed, labour, health, breeding, utilities, depreciation and interest.

Gross margin = gross income − variable costs; it excludes fixed costs such as land rent, permanent labour and depreciation, so use it to compare enterprises of similar scale.

Break-even daily milk yield per animal = daily fixed cost per animal ÷ (milk price per kg − variable cost per kg milk).

Lactation yield estimate = average daily yield × lactation length; the standard 305-day lactation is used for comparison, and peak yield usually occurs 6–8 weeks after calving.

Payback period = initial investment ÷ annual net cash inflow; compare with loan tenure and expected herd life before expansion.

Herd replacement rate = number of replacements entering the herd per year ÷ average herd size × 100; high rates raise rearing costs but accelerate genetic gain.

Value-addition margin = product selling price − raw milk equivalent cost − processing, packaging, energy and wastage costs.

A dairy entrepreneur's first feasibility check is daily saleable volume: perishable milk must have a confirmed outlet within the cooling window, not merely a production plan.

Dairy-type judging looks for a wedge shape, capacious barrel, prominent milk veins, well-attached udder, sound feet and legs, and docile temperament.

Cattle breeds: Gir, Sahiwal, Red Sindhi and Tharparkar are zebu dairy types; Murrah, Jaffarabadi, Mehsana, Surti and Nili-Ravi are buffalo dairy types.

Odisha has locally adapted cattle such as Binjharpuri, Khariar and Motu and Chilika buffalo; local breeds are hardy but usually lower yielding than crossbreds.

Age at first calving target: crossbred cattle 24–30 months, buffalo 30–36 months; later calving increases rearing cost per litre of lifetime milk.

Service period target 60–90 days and calving interval 12–13 months for cattle, 13–15 months for buffalo; longer intervals reduce lifetime yield.

Culling decision: chronic low yield, repeat breeding after three or more services, persistent mastitis, poor udder conformation or untreatable lameness.

Body condition score target around 3.0–3.5 on a 1–5 scale at calving; very thin or overfat cows have more metabolic and fertility problems.

Selection index = weighted sum of estimated breeding values; weights should reflect the economic value of milk, fat, fertility, health and longevity.

Breeding soundness examination of a bull checks libido, testicular size, semen quality, feet and legs, and freedom from transmissible disease before use.

Covered floor space: about 3.5–4.5 m² per adult cow and 5–6 m² per buffalo; open yard 8–10 m² per animal in loose housing.

Manger space: 0.75–1.0 m linear per adult animal; provide one shaded water point per 10–15 animals and clean it daily.

Floor slope 1:50 (about 2%) toward a drain; grooved concrete reduces slipping and urine pooling.

Ridge height 3–4 m and eaves 2.4–2.7 m improve ventilation; avoid drafts on calves and newborn animals.

Farm layout: milk room and milking parlour near the entrance, feed store dry and raised, isolation shed downwind, manure pit and dead-animal site away from water sources.

Calf pens: individual pens about 1.2 m × 2.4 m for young calves; clean dry bedding daily to reduce calf scours and respiratory disease.

Routine: fixed feeding and milking times, twice-daily milking, ad libitum clean water, daily manure removal, weekly footbath and regular hoof trimming.

Stocking density decision: reduce density when ventilation is poor, during hot weather, or when sick animals need separation; overcrowding raises mastitis and lameness.

Dry-off management: reduce feed, check for mastitis, and use dry cow therapy or teat sealant only under veterinary advice before stopping milking.

Dry matter intake: 2.5–3.0% of body weight daily; roughage 60–70% of DM and concentrate 30–40% for lactating cows, adjusted to yield and fat.

Water: 3–5 L per L milk plus maintenance; a lactating cow commonly drinks 60–80 L/day, more in heat.

Rule of thumb for milk synthesis: about 0.07 kg digestible crude protein and 0.35 kg TDN per kg of milk; buffalo milk needs slightly more energy per kg.

Mineral mixture 50–100 g/day and common salt 30–50 g/day for adult dairy animals; adjust to production and mineral content of fodder.

Urea treatment: 4 kg urea in 40–50 L water per 100 kg dry straw, seal 3–4 weeks, aerate before feeding; never feed urea to non-ruminants.

Silage: direct-cut forage at 65–70% moisture, chop 2–3 cm, compact and seal; hay should be dried to below 15% moisture for safe storage.

Legume fodder such as berseem and lucerne supplies protein; cereal fodder such as maize, sorghum and oat supplies energy; rotate legume and cereal crops.

Avoid sudden ration changes: transition over 7–10 days; introduce concentrates gradually to prevent rumen acidosis.

First-cut fodder: maize 60–70 days, sorghum 60–75 days, berseem first cut 50–60 days after sowing; harvest at the recommended stage for quality.

Estrus cycle: 18–24 days in cattle and buffalo, average 21 days; estrus duration about 12–18 h in cattle and 24–36 h in buffalo.

Ovulation in cattle occurs about 10–14 h after the end of standing estrus; AI 12 h after onset of standing heat or use the a.m./p.m. rule.

Gestation: cattle 280–285 days, buffalo 305–310 days; dry-off 60 days before expected calving for cattle and 60–75 days for buffalo.

Pregnancy diagnosis: palpation per rectum from about 35–45 days; ultrasound earlier; confirm before culling or re-insemination.

Sire selection uses predicted transmitting ability or progeny-test results; avoid mating close relatives and rotate bulls to limit inbreeding.

Heat detection signs: standing to be mounted, clear mucus, restlessness, swollen vulva, reduced feed intake; buffalo often show silent or weak heat.

Herd improvement: AI with proven sires, accurate heat detection, record calving dates, cull repeat breeders, and use sexed semen only where fertility management is strong.

Normal values: rectal temperature 38.0–39.0°C in cattle and 37.5–38.5°C in buffalo; respiration 15–30/min; pulse 60–80/min in cattle.

Colostrum: feed within 2 h of birth, about 10% of body weight in first 24 h; colostrum quality declines after 6 h and maternal antibodies are not absorbed later.

Mastitis control: fore-strip, pre-dip, dry, attach unit within 60–90 s, post-dip, keep bedding dry, and use CMT to screen quarters.

FMD control: vaccinate twice yearly in endemic areas, quarantine new animals, restrict visitors, and report vesicular lesions with salivation and fever.

Brucellosis control: calfhood vaccination of female calves and test-and-cull of reactors; avoid contact with placenta and fluids.

Biosecurity: 30-day quarantine for purchased animals, footbath at entrance, separate sick pen, control rodents and birds, and disinfect vehicles.

Notifiable diseases such as anthrax, FMD, HS and BQ require immediate reporting; do not open carcasses suspected of anthrax.

Zoonosis: pasteurize milk, wear gloves for calving and abortion, and dispose of placentas and contaminated bedding safely.

Milk composition standards: cow milk about 3.5–4.5% fat and 8.0–8.5% SNF; buffalo milk about 6–8% fat and 9% SNF; payment often uses fat and SNF.

Fresh milk: density 1.028–1.032, freezing point about −0.54°C, pH 6.6–6.8, titratable acidity 0.14–0.16% lactic acid.

Cool to ≤4°C within 2 h of milking; store at ≤4°C and transport in insulated tanks; never mix warm milk with cold milk.

Pasteurization: LTLT 63°C for 30 min; HTST 72°C for 15 s; UHT 135–150°C for 2–4 s, then aseptic packaging.

Mastitis milk and antibiotic-treated milk must be withheld from the bulk tank for the labelled withdrawal period; test before sale.

Value addition: paneer yield is roughly 16–20% of milk weight; curd, ghee, khoa and ice cream add margin but require hygiene and cold chain.

Adulteration checks: starch with iodine, detergent by lather or chloride test, added water by freezing point or density; record results against supplier or tank.

Break-even units = fixed costs ÷ (price per unit − variable cost per unit); in dairy, use litres of milk or kg of product as the unit.

Working capital = current assets − current liabilities; keep enough to cover feed, labour and veterinary costs until the next milk payment.

NPV = sum of discounted cash inflows − initial investment; accept projects with NPV > 0 and IRR above the cost of capital.

Benefit-cost ratio = discounted benefits ÷ discounted costs; a ratio above 1 indicates viability, but check sensitivity to milk price and feed cost.

Payback period = initial investment ÷ annual net cash inflow; compare with loan repayment schedule and asset life.

Market channel choice: cooperative or private dairy for volume and payment security; direct sale for higher price but more logistics and food-safety responsibility.

Milk pricing: compute per litre and per kg fat/SNF; a higher fat price does not always mean higher margin if feed and cooling costs rise.

Risk management: insure animals and assets, keep a fodder reserve, stagger calving, and maintain a contingency fund for disease outbreaks.

Daily milk record: animal ID, date, morning and evening yield, fat and SNF; total monthly yield is the sum of daily records, not an estimate.

Lactation record: calving date, 305-day yield, peak yield, days in milk, service dates and pregnancy status; use it for culling and breeding.

Cash book: record date, particulars, receipt, payment and balance; reconcile milk payments with milk sold at least monthly.

Depreciation = (cost of asset − salvage value) ÷ useful life; include it in enterprise cost even though it is not a cash payment.

Feed cost per litre = total feed cost in a period ÷ total milk produced in the same period; compare across months to detect ration or price problems.

KPI set: milk yield per cow per day, feed cost per litre, calving interval, replacement rate, calf mortality and somatic cell count.

ICT tools: RFID ear tags, milk analyzers, herd software, SMS/WhatsApp alerts and cloud backup improve traceability; protect animal and farmer data.

Inventory record: feed, medicines, semen, equipment and livestock; physical stock should match the register at each monthly closing.

Five freedoms: freedom from hunger and thirst, discomfort, pain injury or disease, fear and distress, and freedom to express normal behaviour.

PPE for dairy work: gloves for calving and mastitis treatment, boots, masks when handling dust or silage, and handwashing before and after milking.

Zoonoses: brucellosis, leptospirosis, tuberculosis, anthrax and rabies; pasteurize milk, dispose of placentas, and report suspected anthrax.

Manure and slurry: store on an impermeable base away from wells and streams, compost before field use, and never discharge into water bodies.

Dead animal disposal: bury deep away from water or use approved incineration/rendering; do not leave carcasses accessible to dogs or scavengers.

Milking parlour safety: non-slip floor, adequate lighting, guarded belts and pulleys, and electrical fittings protected from water.

Heat stress: provide shade, fans, sprinklers and cool drinking water when temperature-humidity index is high; avoid moving animals in peak heat.

Environmental responsibility: improve feed efficiency to reduce methane, use biogas from dung, plant trees, and avoid overgrazing.
