Achha FCR kitna hota hai? Ross 308 aur Cobb 500 ke asli target

Day 35 par Ross 308 ka target FCR 1.399 hai aur Cobb 500 ka 1.441 — dono company ke apne chart se. Aap ke shed ka number in se ziada aata hai, aur iski wajah chart ki apni footnote mein likhi hui hai: yeh target marne wali murghiyon ka dana hisaab mein nahi lete.

Neeche dono charts ke asli numbers hain, aur woh hisaab jo aap ke shed par lagta hai.

FCR ka formula kya hai?

FCR = kul dana (kg) ÷ kul bike hue gosht (kg). Do hi number chahiye: poore flock ka kul dana, aur sale slips ka kul wazan. Dono ek hi flock, ek hi cycle ke.

Maslan 17,000 kg dana laga aur 10,450 kg gosht bika, to FCR 1.63 hai. FCR jitna kam, ek kilo gosht utna sasta para.

Sirf number nikalna ho to FCR calculator par bags aur wazan daal dein. Yeh article us number ka matlab batata hai — ke woh achha hai ya nahi, aur ziada kyun aa raha hai.

Company ke chart par achha FCR kitna hai?

Ross 308 ka as-hatched target day 35 par 1.399 FCR aur 2,296 g wazan hai. Cobb 500 ka usi din 1.441 aur 2,521 g. FCR har din barhta hai, is liye "achha FCR" hamesha bechne ke din ke saath bolna chahiye — warna number ka koi matlab nahi.

Dono as-hatched (mix male-female) numbers hain, seedha company ke charts se: Aviagen Ross 308/308 FF Broiler Performance Objectives 2022 aur Cobb500 Broiler Performance & Nutrition Supplement 2022.

Cobb ka FCR ziada dikhta hai — kya woh kamzor hai?

Nahi. Ek hi din par compare karna ghalat hai, kyunke usi din Cobb ka wazan bhi ziada hai. Ek hi wazan par dekhein to farq lagbhag khatam ho jata hai.

Ross 308 din 37 par 2,496 g ka hota hai, FCR 1.437. Cobb 500 din 35 par 2,521 g ka hota hai, FCR 1.441. Takreeban wohi wazan, takreeban wohi FCR — sirf do din ka farq.

Yani jab koi kahe "meri nasal ka FCR behtar hai", to pehla sawal yeh hona chahiye: kis wazan par?

Aap ka FCR chart se ziada kyun aata hai?

Chart ek zinda murghi ka hisaab hai. Aap ka hisaab poore shed ka hai. Ross ke chart ki footnote saaf kehti hai ke uska FCR mortality ko hisaab mein nahi leta, aur Cobb ke chart par bhi wohi likha hai. Jo murghi mar gayi, usne dana khaya lekin gosht nahi diya — woh dana aap ke bill mein hai, uska wazan aap ki slip mein nahi.

Misaal se dekhein. Farz karein 5,000 chooze rakhe, 5% mortality ke baad 4,750 bike, average 2.2 kg par:

• Kul bika wazan: 4,750 × 2.2 = 10,450 kg
• Kul dana: 340 bags × 50 kg = 17,000 kg
• FCR = 17,000 ÷ 10,450 = 1.63

Chart ke mutabiq day 35 tak ek murghi 3,211 g dana khati hai. 4,750 zinda murghiyon ka matlab hua 4,750 × 3.211 = 15,252 kg. Aap ne 17,000 kg dala. Farq: 1,748 kg.

Ab is farq ko kholte hain. Agar 250 murghiyan ausatan din 20 ke aas paas maren, to unhon ne takreeban 1,050 g fi murghi khaya hoga (chart ka day-20 number) — yani 250 × 1.05 = 262 kg.

Yeh 1,748 kg mein se sirf 262 kg hai.

Baqi ka takreeban 1,486 kg mortality ne nahi khaya. Woh dana zaya hua, ya garmi mein jala, ya dane ki quality kam thi, ya paani/temperature theek nahi tha.

Yeh is hisaab ki sab se kaam ki baat hai. Aam tor par log samajhte hain ke FCR mortality ne kharab kiya. Numbers dikhate hain ke mortality uska chhota hissa hoti hai — bara hissa zaya hone aur shed ke mahaul ka hota hai. Aur zaya hona qaabu mein aata hai.

Dana ginte waqt kaunsi ghalti hoti hai?

FCR ka aadha number dana hai, aur wohi aadha aksar ghalat gina jata hai. Chaar cheezein check karein:

• Bag ka wazan farz na karein. Ooper wali misaal mein 50 kg fi bag liya gaya — lekin har mill ka bag 50 ka nahi hota. Cycle mein ek bar bag tolein, aur wohi number istemal karein.
• Cycle ke aakhir mein bacha hua dana ghatayein. Jo bags shed mein pare hain, woh khaye nahi gaye. Unhein us cycle ke hisaab mein daalna FCR ko bewajah kharab karta hai.
• Doosre shed ka dana alag rakhein. Agar aap ne ek shed ke bags doosre mein bhej diye, to FCR dono ka ghalat aayega.
• Bill aur dana alag cheezein hain. FCR kilo par chalta hai, rupay par nahi. Udhaar par uthaya gaya dana bhi usi cycle ka hai jis mein khaya gaya, chahe paise baad mein diye.

Wazan kis par taqseem karein?

Kul bika hua wazan, kul dane par — FCR ke liye. Aur jab average wazan nikalna ho, to woh har us murghi par taqseem karein jo zinda rahi (rakhe hue chooze - mortality), na ke sale slip par likhi ginti par.

Wajah seedhi hai: aap har gaari ka wazan karte hain, lekin ginti aksar andaza hoti hai. Slip ki ginti par taqseem karne se aisa average nikal aata hai jo mumkin hi nahi — 6 ya 7 kg ki broiler.

Agar aap ka average wazan chart se bohot ooper aa raha hai, to masla wazan mein nahi, ginti mein hai.

Garmi mein FCR kyun barh jata hai?

Garmi mein murghi kam khati hai aur hanp kar energy jalati hai. Dono cheezein FCR ko ooper le jati hain. Aviagen ke Ross 308 chart ki management guidance kehti hai ke din 21 ke baad shed ka temperature 21°C se kam rakhna growth behtar kar sakta hai — aur wohi document yeh bhi likhta hai ke sakht mausam performance kam kar deta hai.

August ke Punjab mein 21°C rakhna aasan nahi. Lekin isi liye garmi ke flock ka FCR sardi ke flock se compare karna theek nahi hota. Har cycle ka apna number rakhein, aur mausam ke saath parhein.

FCR behtar karne ka pehla kadam kya hai?

Har flock ka alag hisaab rakhna. Saal ka average yeh nahi batata ke kaunsa cycle kharab gaya aur kyun — aur jo cheez alag se nazar na aaye, woh theek bhi nahi hoti.

Ek cycle par sirf teen cheezein poori tarah likhein: kul bags, kul mortality, aur har gaari ka wazan. In teen se FCR khud ban jata hai.

Rozana likhne ka faida koi jadoo nahi hai. Faida sirf yeh hai ke ghalti cycle ke darmiyan pakri jati hai. Jo baat flock bikne ke baad pata chale, woh us flock ko nahi bacha sakti.

Rozana log rakhna ho to PoultryFast yeh hisaab khud banata rehta hai. Aur FCR ke baad asal sawal munafa ka hota hai — uske liye munafa calculator dekhein.
