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

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

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 :

Procedure of dip treatment : 

16 August 2009 19 Procedure of dip treatment --------- --------- - ------- 1.5% NaOH - - - - - Soaking-2 ½-1 h Solution-1 ----------- ----------- Dripping-3 ½-2 h ------------- ------------- 0.6 kg NaOH 30 l H2O Replenishment/10 kg straw Straw Straw Straw Straw Ripening 3-6 days Feeding

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

Conservation of feed and fodders : 

16 August 2009 40 Conservation of feed and fodders Fodders can be conserve as Silage and Hay Silage Anaerobic fermented feed possess all the quality of fodder High moisture feed Suitable crops are Maize, Jowar, Grasses etc. Harvesting of crops at flowering stage moisture content Should not be <60-65%
