Introduction |
· The Upkeep And Proper Management Of Young Calves Are A Prerequisite To The Success Of Any Dairy Development Programme. An Optimum Level Of Nutrition In Early Life Favours Faster Growth And Earlier Onset Of Puberty. Calves Should Be Reared Carefully To Obtain Optimum Gain In Body Weight, So That They Attain About 70-75 Per Cent Of Mature Body Weight At Puberty. Poor Feeding Of Young Calves Leads To Higher Age At First Calving And Overall Loss Of Productivity In The Life Span. Therefore, Milk Producers Need To Recognize The Implications Of Poor Feeding Of Young Calves. |
Importance Of Colostrum Feeding To Newly Born Calves |
· Colostrum Is The First Secretion Produced By The Mammary Gland Of Cows/Buffaloes After Calving, A Rich Source Of Protein, Fat, Minerals And Antibodies.· The Calf Should Receive Colostrum Within 1-2 Hours Of Birth. The Gut Of The Newborn Calf Is Able To Absorb Maternally-Derived Immunoglobulins (Antibodies) Contained In Colostrum And Transport Them Into The Bloodstream. Antibodies Transferred From The Dam To The Calf In This Way Are Referred To As “Passive” Antibodies. The Ability Of The Calf To Absorb These Colostral Antibodies Is Maximum Within The First Hour Following Birth And Remains Fairly Good For Up To Six Hours. After This, There Is A Progressive Loss In The Calf’s Ability To Absorb Cloistral Antibodies. On An Average, The Calf Should Receive 3-4 Meals Of Colostrum Within The First 24 Hours Of Its Life. |
Importance Of Colostrum Feeding |
· Newly Born Calves Have Very Low Resistance To Disease Buffalo Calves Have An Even Lesser Resistance To Diseases As Transfer Of Antibodies From The Dam To Calf Through The Placenta Is Very Low. |
· Colostrum Is An Invaluable Gift Of Nature To Newly Born Cal Compared To Whole Milk It Contains 4-5 Times Protein, 10 Times Vitamin A And Plenty Of Minerals. |
