Introduction :16 August 2009 3 Introduction India
Indian economy is fastest growing
India is the 12th largest economy of the world
GDP growth was 9.0% and 9.2% during 2005-2006 and 2006-2007
The share of agriculture in GDP is declining continuously From 24 to 18.5%
Second largest producer of fruit &vegetables (150 MT)
Slide 4:16 August 2009 4 India
Third largest producer of food grain
3rd largest country in fish production
Largest population of livestock (20%) and its contribution to Ag GDP is @ 24%
Largest producer of milk in the world (100 MT)
Milk alone contribute >18% of TO from agriculture Introduction

Slide 12:16 August 2009 Danisco Animal Nutrition Digestive system
Non Conventional Feed Resources :16 August 2009 Danisco Animal Nutrition Non Conventional Feed Resources Non competitive unconventional feedstuffs may bridge the gap between demand and supply of nutrients
Feeding at higher level and for longtime can cause adverse effect on animal performance
They can be converted into wholesome animal feeds after suitable processing
Besides annually cultivated, 86 different oil bearings perennial trees are present in India
Availability and their nutritional value of some non conventional feeds resources :16 August 2009 Danisco Animal Nutrition Availability and their nutritional value of some non conventional feeds resources
Potential of horticultural crop residues as animal feed :16 August 2009 Danisco Animal Nutrition Potential of horticultural crop residues as animal feed India is second largest producer of the vegetables and fruits
About 33% is wasted during harvesting, marketing and processing (Gangadhar et al., 1993)
Gap between demand and supply could be lessened
High moisture content is one major problem (Datt et al., 2008)
Utilize efficiently after processing
Proximate composition of some important horticultural crop residues :16 August 2009 Danisco Animal Nutrition Proximate composition of some important horticultural crop residues Vegetable crop residues Datt et al.(2008)

Mode of Action :16 August 2009 Danisco Animal Nutrition Mode of Action CHO C O CO Lignin Alkali Ester linkage Carbohydrates C OH + COOH Lignin
Non Protein Nitrogen (NPN) :16 August 2009 21 Non Protein Nitrogen (NPN) Nitrogen supplied to the animal in a non-protein state
Urea or Biuret
Requires microbial synthesis (Ruminants)
Crude Protein Equivalent
% Nitrogen from NPN times a factor of 6.25
Urea :16 August 2009 22 Urea Supplementation Treatment Feeding of NPN has
become a focal point and needs C Skeleton
for AA synthesis NH2 NH2 + H2O Urease O=C CO2 + 2NH3
Factors affecting urea utilization :16 August 2009 23 Factors affecting urea utilization Source of energy
Level and source of protein
N:S Ratio
Frequency of feeding
Level of urea in feed
Urea Toxicity (NH3 Toxicity) :16 August 2009 24 Urea Toxicity (NH3 Toxicity) Mechanism
Rumen [NH3]  Rumen pH 
As pH , shift from NH4+ to NH3
NH3 absorbed faster than NH4+
Liver capacity to convert NH3 to urea is exceeded
NH3 goes to blood
2 mg NH3/100 ml plasma is toxic
Urea Toxicity (NH3 Toxicity) :16 August 2009 25 Urea Toxicity (NH3 Toxicity) Signs of toxicity
Appear 20-30 min after urea ingestion
Excessive salivation
Rapid and labored breathing
Tremors
Incoordination
Inability to stand & tetany
Treatment :16 August 2009 26 Treatment Orally dose with 5% acetic acid
(~1 gal. for 1,000 lb cow)
Shift equilibrium from NH3 to NH4+
 rate of absorption
Vinegar drenching
Drench with cold water
 rumen temp. which  rate of urea hydrolysis
Dilutes NH3 concentration
Takes 6-12 gal.; not practical when several sick
Prevention :16 August 2009 27 Prevention Prevention
Mix feeds well
Don’t switch rapidly from natural protein to urea
Always have feed available
Don’t allow hungry animals access to highly palatable, high urea diet, feed, or supplement (including lick tanks)
Don’t use urea with low-energy feeds

Silage
Anaerobic fermented feed
possess all the quality of fodder
