Bhumika: FAT aur SNF kyun zaroori hain?
Agar aap doodh ka business karte hain, to aapne apne doodhwale bhaaiyon se zaroor suna hoga — "Bhai, aaj ka FAT kam hai, rate cut gaya." Ya "Is baar to SNF bahut achha hai, bonus milega." Ye do shabd — FAT aur SNF — aaj ke zamane mein doodh ka rate tay karte hain.
Pehle jahan doodhwale bhai sirf litre ke hisaab se paise lete the, ab co-operative dairies (Amul, Mother Dairy, Saras, Gokul) aur zyaadatar bade kharidaar FAT aur SNF dono dekhkar rate dete hain. Matlab yeh hai ki agar aap in dono cheezon ko nahi samajhte, to ho sakta hai aapko har din ₹2-5 per litre kam mil rahe hon — aur mahine ke aakhir mein yahi nuqsaan hazaaron rupaye ka ban jaata hai.
Is guide mein hum bilkul aasaan tarike se samjhenge:
- FAT kya hota hai?
- SNF kya hota hai?
- Dono ko kaise maapa jaata hai?
- Rate kaise nikalta hai?
- Gaay aur bhains ke doodh mein kya antar hai?
- Example ke saath poora hisaab
- Accha FAT/SNF kaise banaye rakhein
Chaliye shuru karte hain.
FAT kya hai? (What is Milk FAT?)
FAT ka matlab hai vasa (butterfat) — yaani doodh mein jo "cream" wala hissa hota hai, jisse makkhan, ghee aur khoya banate hain. Yeh doodh ka sabse kimti hissa hai. Jab aap doodh ko thodi der ke liye rakh dete hain, to upar jo peeli parat jam jaati hai — wahi FAT hai.
FAT ko percentage mein maapa jaata hai. Matlab agar koi kahe ki "doodh mein 4% FAT hai", to iska matlab hua ki 100 litre doodh mein lagbhag 4 litre vasa hai (wazn ke hisaab se).
FAT ki normal matra
Alag-alag jaanwar ke doodh mein FAT alag-alag hota hai:
| Pashu | Normal FAT % | Achha FAT % |
|---|---|---|
| Gaay (Cow) | 3.5% - 4.5% | 4.0% se upar |
| Bhains (Buffalo) | 6.0% - 8.0% | 6.8% se upar |
| Bakri (Goat) | 4.0% - 5.0% | 4.5% se upar |
Matlab saaf hai — bhains ka doodh FAT ke mamle mein gaay se lagbhag dedh se duguna richer hota hai. Isi wajah se mithai ki dukano aur halwaiyon ko bhains ka doodh zyaada pasand aata hai.
SNF kya hai? (What is SNF?)
SNF ka poora naam hai Solids-Not-Fat — yaani "vasa ko chhodkar baaki sab thosi padarth". Doodh mein paani aur FAT ke alaawa jo kuch bhi hota hai — protein, lactose (doodh ki shakkar), calcium, phosphorus, vitamins — yeh sab milkar SNF banate hain.
Aasaan bhasha mein kahein to:
Doodh = Paani + FAT + SNF
SNF bhi percentage mein maapa jaata hai. Aur yeh FAT jitna hi zaroori hai, kyunki jab bhi aap doodh se paneer, dahi ya khoya banate hain, to sirf FAT nahi — SNF bhi utna hi kaam aata hai.
SNF ki normal matra
| Pashu | Normal SNF % | Achha SNF % |
|---|---|---|
| Gaay | 8.0% - 8.7% | 8.5% se upar |
| Bhains | 8.8% - 9.5% | 9.0% se upar |
Dono ko kaise maapa jaata hai?
Doodh mein FAT aur SNF maapne ke kai tarike hain — purane zamane se lekar aaj ke electronic machines tak:
1. Lactometer — sabse sasta tarika
Lactometer ek chhota sa sheeshe ka yantra hota hai jo doodh ki density maapata hai. Iski keemat sirf ₹150-300 hoti hai. Isse aap turant paani milawat pakad sakte hain. Lekin akele lactometer se aap sateek FAT nahi nikaal sakte — yeh sirf SNF ka andaza deta hai.
2. Gerber Method — paramparagat pakka tarika
Isme 10 ml doodh ko 10 ml sulphuric acid aur 1 ml amyl alcohol ke saath butyrometer mein daalkar centrifuge mein ghumaya jaata hai. Yeh tarika aaj bhi BIS ka reference method hai. Har sample par ₹3-5 ka kharcha aata hai aur 15-20 minute lagte hain.
3. Lactoscan jaisi electronic milk analyser — aadhunik aur tez
Aajkal zyaadatar co-operatives Lactoscan ya isi tarah ki ultrasonic machine istemal karte hain. Ek sample ko machine mein daalte hi 60 seconds mein FAT %, SNF %, density, added water %, protein % — sab kuch screen par aa jaata hai. Machine ki keemat ₹60,000 se ₹2,00,000 tak hoti hai.
Agar aap 200+ customers wale doodhwale hain, to Lactoscan ka kharcha 6-12 mahino mein hi vasool ho jaata hai.
Rate kaise nikalta hai?
Zyaadatar co-operative dairies two-axis pricing karti hain — yaani FAT par ek rate aur SNF par ek rate. Aasaan tarika yeh hai ki kai dairies flat rate chart deti hain jisme seedha likha hota hai "6.0% FAT, 9.0% SNF = ₹52/litre". Yeh chart dekhkar aap turant rate samajh sakte hain.
Amul-jaisi flat rate chart (April 2026 ke lagbhag)
| FAT % | SNF % | Rate per litre |
|---|---|---|
| 6.0 | 9.0 | ₹52 |
| 6.5 | 9.0 | ₹56 |
| 7.0 | 9.0 | ₹60 |
| 7.0 | 9.2 | ₹62 |
| 7.5 | 9.2 | ₹65 |
Agar aapka FAT ya SNF base se kam hai, to cut rate lagta hai — yaani katauti. Aur agar zyaada hai, to bonus rate milta hai.
Example calculation — bhains ka doodh
Maan lijiye ek doodhwale bhai ne subah ke 20 litre bhains ka doodh Amul collection centre par diya. Lactoscan mein report aayi:
- FAT: 7.0%
- SNF: 9.2%
Upar chart se rate ₹62/litre.
Kul aay = 20 × 62 = ₹1,240.
Ab sochiye — agar doodh mein 0.5% FAT kam ho jaata (yaani 6.5%), to rate girkar ₹56 ho jaata. 20 litre par aay = ₹1,120 — yaani ₹120 kam. Poore mahine (30 din) ka hisaab lagayen to yeh ₹3,600 ka nuqsaan hai, sirf 0.5% FAT girne se.
Gaay aur Bhains ke doodh mein antar
| Baat | Gaay ka doodh | Bhains ka doodh |
|---|---|---|
| FAT | 3.5-4.5% | 6.0-8.0% |
| SNF | 8.0-8.7% | 8.8-9.5% |
| Total Solids | lagbhag 12.5% | lagbhag 16% |
| Rate per litre (retail) | ₹55-65 | ₹80-95 |
| Mithai/khoya ke liye | theek | sabse achha |
| Supaachya | halka | bhaari |
| Bachcho ke liye | pasandida | kam |
Yaad rakhein: bhains ka doodh FAT-SNF ke aadhar par aapko ₹20-30 per litre tak zyaada dila sakta hai, lekin iski feeding cost bhi zyaada aati hai. Gaay ka margin kam hai par steady hai.
Achha FAT/SNF kaise banaye rakhein?
Ab sawaal yeh hai — agar FAT aur SNF hi rate tay karte hain, to aap unhe kaise badha sakte hain? Yeh kaam jaanwar ke saath hi shuru hota hai:
- Achha chaara dein: hara chaara, khali, daana — jitna behtar feed, utna behtar FAT. Summer mein hara chaara kam ho jaaye to silage ya hydroponic fodder kaam aata hai.
- Doodh nikaalane se pehle than dhoyein: saaf-safai se bacterial count kam rehta hai, jisse SNF girta nahi.
- Paani kabhi mat milayen: yeh sirf beimani nahi — lactometer pakad leta hai. Paani milaane se SNF girta hai aur CLR (corrected lactometer reading) turant bata deta hai ki kitna paani mila hai.
- Milking ke beech gap sahi rakhein: subah-shaam ki milking ke beech 10-12 ghante ka gap rakhein. Agar gap kam ya zyaada hua to FAT gir sakta hai.
- Tanaav se bachaayein: garmi, shor, badlaav — jaanwar tanaav mein aaye to doodh aur FAT dono girte hain. Chhaon, pankha aur saaf baada zaroori hai.
- Regular health check-up: mastitis (thanaila) ya koi aur bimari SNF ko 0.5-1% tak gira sakti hai. Pashu doctor se mahine mein ek baar zaroor jaanch karayen.
Agla qadam: apna hisaab digital karein
FAT-SNF pricing sirf samajhna kaafi nahi hai — ise track karna bhi utna hi zaroori hai. Har customer ya har supplier ka FAT, SNF, litre aur rate alag-alag ho sakta hai. Purani khata-bahi mein yeh sab likhna aur har mahine hisaab lagaana — bahut mehnat ka kaam hai.

FAT aur SNF — ye do shabd doodh ke poore business ki neenv hain. Jo doodhwala inhe samajhta hai, woh apne doodh ki sahi keemat leta hai. Jo nahi samajhta, woh har mahine hazaaron rupaye ka nuqsaan kar baithta hai.
Yaad rakhein:
- FAT = makkhan/ghee wala hissa, 3.5-8% tak hota hai
- SNF = protein + lactose + minerals, 8-9.5% tak hota hai
- Dono milkar aapka rate tay karte hain
- Lactoscan machine sabse sateek tarika hai
- Achha chaara aur saaf-safai se FAT-SNF badhaaya ja sakta hai
Apne har customer aur supplier ka FAT-SNF track karna shuru karein — yahi aage badhne ka pehla qadam hai.
