Basic Definitions and Terminologies
BalancedDiet→Onewhichprovidesdifferentkindsofnutrientsincertainquantities
andproportionsofalltherequirednutrients
Optimizing→ Make the best use of a resource (or) Most effective use of a resource
Animal Production → Meat, milk and eggs
Animal Productivity → Birth rate, mortality rate, off-take rate, etc.

Underfeeding→Deficiencydisordersandillhealth(reducedimmunity)
Underfeeding→Reducedgrowth,reproductionandproduction
Fodders(greenanddry)→PlayamajorroleinRuminantration

Current Scenario in Balanced Feeding -India
Dairycows→Poorlyadopted(70%dairyfarmersarelandlessandmarginalfarmers)
SheepandGoat→Poorlyadopted
Swine→Poorlyadopted(Non-availabilityofcommercialfeedsinthemarket)
Poultry→Comparativelywelladopted(Integrationsystem)
FishandShrimp→Comparativelywelladopted
Problems Solutions

Why Balanced Ration?
Dairycows
Priortowhiterevolution
Low milk yield
Mainly for manure, plowing and bullock carting
Verygoodpastures,grazinglands→Nutritionalneedsaremet
Afterwhiterevolution→Dairyingbecameanindustry
Geneticimprovement(Crossbreeding)→↑milkyieldandfastergrowthrate
Mainlyformilkproduction
Lackofpasturesandgrazinglands
Transitionofproductionpractice→Free-rangegrazingtoconfinedhousing
Concentratefeedingisessentialtomeettherequirements
Poultry→Backyardtodeeplitterorcagesystem
Fastergrowthrateofbroilers→from9weeksitcameto6weeks
Layers→from100eggsto300eggs

Benefits of Balanced feeding –Dairy cows
Improvementinmilkproduction&quality(fatandSolids-not-fat(SNF))
Possiblereductionindailyfeedingcost→↑innetdailyincome
Improvementinreproductionefficiencyofanimals
Reductionincalvingintervalandasaresultincreaseinproductivelife
Improvementinthegrowthrateofcalves→earlymaturity&calving
Betterimmuneresponse,hencebetterresistanceagainstdiseases(↑IgG,IgMandIgA)
Reductioninmethaneemission(15–20percentperkgmilkproduced)
Reductioninnitrogenexcretion

Fodderandcropresidueutilization
Ricestraw→baling→avoidburning
Ricestraw→bulkyfeedsforruminants
Paddystraw/wheatstraw→ureatreatment
Green/dryfodder→chaffing→reducewastageandimprovesdigestibility
Chaffcutter(hand/poweroperated)
Hydroponicfodderproduction
Surplusgreenfodder→silagemaking

Total Mixed Ration (TMR)

Thumb Rule for Feeding Dairy Cattle
Water
3kgwaterforeverykgofdrymatterintake(winterandsummervariation)
1.5to1.8kgwaterforeverykgmilkproduced
DMI→2.5kgper100kgbodyweight
Greenfodder→3to5kgper100kgbodyweight
Dryfodder→1to2kgper100kgbodyweight
Concentrate
Formaintenance→1.5kgperdaypercow(forindigenouscrossbredcattle)
First2.5kgmilkproduced→Maintenancerationissufficient(1.5kgperdaypercow)
>2.5kgmilkproduced→everykgmilkproduced0.4kgadditionalconcentrate+M
Pregnancy→Lasttrimester(>monthofpregnancy)→(M+P+1to1.5kgper100kgbwt)

Summary
Inlivestockrearing,65-70%ofthetotalcostisattributedtofeeding
Minimizingtheexpensetowardsfeedingincreasestheprofit
Majorityofdiseases,reproductiveproblemsandlessmilkproductionoftheanimalsare
relatedwiththefaultynutritionoftheanimals
