Period – 01 (Challenge period)Period of early lactationRapid increase in milk yieldAmount of concentrate should be increased gradually till cow consumes
800-1000 gm conc./100kg BW
Concentrate allowance 500 gm/day for first two weeks
Slide11Periods of nutrition requirement
Period – 02Period of mid and late lactationMilk yield remains staticFeeding of balanced ration as per milk yield
Provision of good quality fodder/silage
Slide12Periods of nutrition requirement
Period – 03 (Dry period)Period of advance pregnancyWithdrawn/halting of milk removalRemodeling of mammary tissue and preparatory phase for subsequent lactationPeriod divided in two phasesFar-off and Close up periods
Slide13Far-off period
From beginning of dry period to 03 weeks before calvingMaintaining optimum dietary fiber contentLimiting energy intakeAvoiding an overfeeding of crude proteinMeeting mineral and vitamin requirements.
Slide14Close up period
Period starts 03 weeks before calvingTransfer animal to separate housingFeed intake reduces drastically before 07-10 days prepartum Less volume of feed but high frequency of feedingProvide energy dense feed having RUDP
60-76 cm feed bunk space to avoid aggressiveness
Provision of adequate bedding material
eg
. Paddy/sand layer etc

Slide16Calving Management
Before parturitionIsolate animal from rest of the herdProvide ample bedding materialEveryday provide Vitamin D supplementationDO NOT
supplement
calcium
DO NOT milk animal
During parturition
Primary clinical examination – Rectal\temperature/activity/inspection of vulva
Maintain hygiene around animal
Slide17Management just after parturition
If animal is recumbent – Massage of hind quarter
Observe expulsion of placenta
Discourage/avoid
placentophagy
Cleaning of body specially hind quarter with moderate-warm water and added KMNO
4
Provide Luke warm drinking water
Carefully observe animal behavior – if sluggish/mostly recumbent/dull –
Provide calcium supplementation
Slide18Overall health management
VaccinationPre-calving vaccination with Calf scours(Rota, corona viruses, E.coli, Clostridium perfringens
C, D)
Before breeding – FMD, IBR-IPVV, BVD,
Leptospirosis
,
Vibriosis
Deworming
– pre-partum with pregnancy safe anthelmintics, post partum – benzimidazole gp
