New trends in livestock feeding include using hydroponics to grow fodder, producing azolla as a protein-rich feed supplement, and creating total mixed ration feed blocks. Hydroponic fodder production provides fresh, green fodder year-round and more efficiently uses water. Azolla is a fast-growing aquatic fern rich in protein, vitamins and minerals that can be used to supplement livestock diets. Total mixed ration blocks provide a balanced feed by compacting forages, concentrates and molasses into a portable block form.

Fodder for sustainable Dairy Farms
Hydroponics is a subset of hydroculture and is a method of
growing plants using mineral nutrient solutions, in water,
without soil.
Terrestrial plants may be grown with their roots in the mineral
nutrient solution only or in an inert medium, such
as perlite, gravel, biochar, mineral wool, expanded clay pebbles or
coconut husk.

13. KEY FACTS
•The digestive system of ruminating mammals,
does not fit to grain-fed.
•Up to 25% of indigestion and lactic acidosis from
rapid fermentation of grain lead to dehydration,
heart failure, kidney failure, infertility and even
death
•Feeding with fresh green fodder allows their
digestive system to function to maximum
efficiency.
Hydroponic Fodder provides, year round, clean & fresh green fodder, increasing red blood cell
count to more oxygen in blood system, more & high quality protein, enzymes and vitamins at
highest digestibility.

18. Azolla- As Livestock Feed
• Azolla is a floating fern which resembles algae
• Normally azolla is grown in paddy fields or shallow water bodies
• Multiplies very rapidly
• Azolla an aquatic fern is regarded as “Live Nitrogen Manufacturing Factory”
because, it harbors nitrogen fixing Cyanobacteria.
• Azolla has been extensively used both as biofertilizer and green manuring for rice
cultivation in the South East Asian countries. More than 50 % nitrogen can be
supplemented when Azolla dual cropped with rice.

19. Azolla as fodder/ feed
• Rich in proteins, essential amino acids, vitamins (vitamin A,
vitamin B12 and Beta- Carotene), growth promoter
intermediaries and minerals like calcium, phosphorous, potassium,
ferrous, copper, magnesium
• Dry weight basis, it contains 25 - 35 percent protein, 10 - 15
percent minerals and 7 - 10 percent of amino acids, bio-active
substances and bio-polymers
• Livestock easily digest it, owing to its high protein and low lignin
content
• Azolla can be mixed with concentrates or can be given directly to
livestock
• Can also be fed to poultry, sheep, goats, pigs and rabbits.

20. Azolla Production
• The soil in the area is first cleared of weeds and leveled
• Bricks are lined horizontally in a rectangular fashion.
• A UV stabilized silpauline sheet of 2mX2m size is
uniformly spread over the bricks in such a way as to
cover the margin of the rectangle made by the bricks
• 10-15 kg of sieved soil is uniformly spread over the
silpauline pit
• Slurry made of 2 kg cow dung and 30 g of Super
Phosphate mixed in 10 liters of water, is poured onto
the sheet. More water is poured on to raise the water
level to about 10 cm

21. • About 0.5-1kg of pure mother azolla culture
seed material is spread uniformly over the
water, after mild stirring of soil and water in
the azolla bed. Fresh water should be sprinkled
over the azolla immediately after inoculation to
make the azolla plants upright
• In a week’s time, the azolla spreads all over the
bed and develops a thick mat like appearance.
• A mixture of 20 g of Super Phosphate and
about 1 kg of cow dung should be added once in
5 days in order to maintain rapid multiplication
of the azolla and to maintain the daily yield of
500 g

22. • A micronutrient mix containing magnesium, iron, copper, sulphur etc.,
can also be added at weekly intervals to enhance the mineral content of
azolla
• About 5 kg of bed soil should be replaced with fresh soil, once in 30
days, to avoid nitrogen build up and prevent micro-nutrient deficiency
• 25 to 30 percent of the water also needs to be replaced with fresh
water, once every 10 days, to prevent nitrogen build up in the bed
• The bed should be cleaned, the water and soil replaced and new azolla
inoculated once every six months
• A fresh bed has to be prepared and inoculated with pure culture of
azolla, when contaminated by pest and diseases

23. Harvesting
• Will grow rapidly and fill the pit within 10 - 15 days. From
then on, 500 - 600 g of azolla can be harvested daily.
• Can be done every day from the15th day onwards with the
help of a plastic sieve or tray with holes at the bottom
• The harvested azolla should be washed in fresh water to get
rid of the cow dung smell

24. Alternative Inputs
• Fresh biogas slurry may also be used
• Waste water from bathroom and cattle shed can also be
used to fill the pit. In areas where there is a problem of fresh
water availability, the water left after washing clothes (after
the second rinsing) can also be used.

25. Environmental factors for the growth
• Temperature 20°C - 28°C
• Light 50% full sunlight
• Relative Humidity 65 - 80%
• Water (standing in the tank) 5 - 12 cm
• pH 4-7.5

26. Points to be noted during cultivation of azolla
• Washing in a net will be useful as it will allow small plantlets
to get out, and they can be poured back in to the pond
• Care should be taken to retain the temperature below 25°C.
• Shade nets can be used to cut the light intensity.
• The azolla biomass should be removed daily to avoid over
crowding.

31. Earthworms - an animal feed alternative
• Earthworm meal is a protein dry extract which
reaches concentrations around 64-70 %.
• The modern earthworm feed shape was technically
elaborated so that amino acids compounding proteins
are isolated and independent. Amino acids are basically
provided as a compound with two functions –o from
Amin (-NH) and Acid (-COOII).
• Amino acids are immediately absorbed in the
gastrointestinal mechanism which increases the food
material and hence decreases absorption.
• All essential amino acids must be present in the due
rates and associated to mineral salts and vitamins, so
that the organism may use and synthesize protein
effectively.
• The earthworm meal is being incorporated to feed for
all kinds of animals and phases.
GUARANTEED LEVELS:

Fat ……………………………… 6,56 %
Fibres ………………………… 3,3 %
Carbohydrates ………… 17,60 %
Mineral Material ………… 7,59 %

32. Earthworm meal is recommended for:
• Fish, frog, and crustacean breeding
• Ornamental fish breeding
• Aviculture and sportive birds
• Chinchillas and ornamental birds
• Equitation, race, and domestic horses
• Cattle, swine, sheep, and goat studs
• Dairy cattle
• Pet food

33. Total mixed ration & Densified Complete
Feed Blocks (DCFBs)
• Total Mixed Ration (TMR), which involves
mechanical mixing of forages with concentrate
feedings without densification.
• Manufacture of Straw-based Densified Total Mixed
Ration Blocks (DTMRBs), also called Densified
Complete Feed Blocks (DCFBs) is an innovative
technology to supply balanced feeds to the dairy
and other livestock farmers in the tropics.
• This technology of making DTMRBs has now been
commercialized in India and the manufacturing
plants have been set up in different states under
Dairy Cooperatives and State level Livestock
Boards, with Government providing the incentive
by way of offering 50% subsidy for setting up of
such plants.

34. • The first step in the process of making DTMRBs is the grinding
and mixing of concentrate ingredients separately.
• This is followed by adding concentrate components to chopped
straw in desired proportions along with molasses in a mixer,
taking care that mixing is uniform and ingredients are not
separated due to gravity.
• Finally, the desired quantity of straw-concentrate mix is
transferred to a hydraulic press to convert the mix into a
block.
• Recently, a modified version of the technology has been
developed, and the densified total mixed ration is delivered as
pellets (DTMRPs).

40. Nutraceuticals
the words “nutrition” and “pharmaceutical”, is a food or food
product that provides health and medical benefits, including the
prevention and treatment of disease.

42. Solid-state fermentation (SSF)
• Solid-state fermentation (SSF) is defined
as the fermentation process in which
microorganisms grow on solid materials
without the presence of free liquid
• The SSF is alternative to submerged
fermentation for production of value
added products like antibiotics, single
cell protein, Poly unsaturated fatty
acids, enzymes, organic acids,
biopesticides, biofuel and aroma
production

43. Solid state fermentation
• Allow the growth of white rot fungi
(Basidomycetes) on crop residue
• Principle: This fungi releases Mn. Peroxidase,
laccase and lignin peroxidase.
• Karnal process:
• 1st stage: primary treatment with 4% urea +
40% water = ensiling for 40 days
• 2nd stage: this material mix with 1% super
phosphate + 0.1% CaO + raise the moisture up to
65-70% + 3% inoculation of Coprinus
filamentaris (alkali tolerant strain)

44. Use of plant secondary
products-Methane

effectiveness of a particular strategy
depends on
 the cost of the item,
 economic status of livestock keeper,
 toxicity to host animal or inhabiting
microbes,
 persistency etc.

• The process of digestion and metabolism referred to as enteric
fermentation causes 2–12% loss of dietary energy as methane (CH4) in
ruminants.
• Loss of energy as CH4 from diets/feeding systems varied from 6.48% to
12.56% in buffalo, 6.6% to 12.09% in goat and 6.16% to 12.62% in
sheep.

47. Saponins
• inhibitory action of saponins on protozoa - interspecies
hydrogen transfer to methanogens
• Yucca schidigera, Quillaja saponaria, Enterolobium cyclocarpum,
Sesbania sesban, Medicago sativa, Sapindus saponaria, Sapindus
rarak and Sapindus mukorossi
• saponin containing plants - suppressing or eliminating protozoa
• saponins are differentially toxic to rumen protozoa - presence
of
cholesterol in eukaryotic membranes but not in prokaryotic
Plant secondary compounds
(Hess et al. 2003, García- González et al.2008, Rejil et al. (2008)

48. Supplementation of tannins in feed
• Tannins are a complex group of
polyphenolic compounds.
• classified into two major groups: the
hydrolysable and the condensed
tannins.
• low to moderate concentrations
improve the digestive utilization of
feed mainly due to a reduction in
protein degradation in the rumen
and a subsequent increase in amino
acid flow to the small intestine.
• decreases emissions of CH4 from
sheep by reduction of methanogen
and protozoa populations.
(Berra et al. 2008, Bhatta et al. 2009)

49. Supplementation of probiotics in feed
• Probiotics are ‘live microorganisms which when administered in adequate amounts
confer a health benefit on the host’ (FAO).
Effect on micro biota composition &
metabolic effects
 Suppression of endogenous &
endogenous pathogens
 Reducing the risk of intestinal
diseases
 Inhibition of toxins originated from
blood
 Immune modulation
 Tolerance to different foods
 Enhanced innate immunity
 Increased nutrient absorption

50. Dicarboxylic acids (Iqbal et al. 2008, Sirohi et al. 2009)
• Increased propionate production (Bayaru et al. 2001)
 proliferation of cellulolytic bacteria (Asanuma et al. 1999)
• Eg: High malate content in fresh forages at early growth stage
especially lucerne (Martin 1998), encapsulated fumaric acid in the diet
of sheep Wallace et al. (2006)
Essential oils
• essential oil thymol derived from thymus and origanum plants
Evans and Martin(2000)
 garlic oil and diallyl disulphide Busquet et al. (2005)
 rosemary (Rosmarinus officinalis) - potential inhibitor of the protozoa
• inhibition is concentration dependent Rasmussem et al.(2005)

52. Animal manipulation
• Animal breeding could achieve a 10%–20% reduction in CH4
losses from dry matter (DM) during digestion(Waghorn et
al., 2006).
• However, breeding for reduced methanogenesis is unlikely to
be compatible with other competing breeding objectives.
• improved for feed conversion efficiency,
• reduce both CH4 and the ratio of CH4 per unit producer
• Reducing the number of unproductive animals on a farm can
potentially both improve profitability and reduce CH4.

53.  extended lactation in dairying - cows calve every 18 months
rather than annually, reduce herd energy demand by 10.4%
(Trapnell and Malcolm, 2006).
 With earlier finishing of beef cattle in feed lots, slaughter
weights are reached at a younger age, with reduced lifetime
emissions per animal and thus proportionately fewer animals
producing CH4 (Smith et al., 2007).
 increase the stocking rate, resulting in either no net change or
even a net increase in CH4 production.
 the addition of more grain to the diet will incur additional
N2O and transport emissions during the grain production
processes

 Improving forage quality
 lower fiber and higher soluble carbohydrates,
• changing fromC4 to C3 grasses, or grazing on less-mature
pastures (Ulyatt et al., 2002; Beauchemin et al., 2008),
 addition of grain to forage diet increases starch and reduces fiber
intake, reducing the rumen pH and favouring the production of
propionate rather than acetate in the rumen(McAllister and Newbold,
2008)

57. • Direct inhibition of methanogenesis by halogenated methane
analogues and related compounds has been widely
demonstrated invitro.
• Chloral hydrate – converted to chloroform ( prolonged use
causes liver damage and death) inhibited methane
production in vivo
• Trichloroacetamide, trichloroethyl adipate,
bromochloromethane combination of bromochloromethane
and a-cyclodextrin.
• 2-bromoethanesulfonic acid (BES), 9,10-anthraquinone.

58. Dietary supplementation
• Dietary oils
fats
Indirect: protozoal inhibition by
reduction of double bonds in
unsaturated fatty acids,
increase propionate production
Direct: causing toxicity
directly to methanogens by
changing their metabolic
activity and composition
(Machmuller et al.1998) (Machmüller et al. 2003)

59. Limitations
• reduces fiber digestion (McGinn et al. 2004)
• Reduced microbial protein(Dong et al. 1997)
• negative effect on milk fat concentration
• adverse effect on animals
• High cost (Zheng et al. 2005)

60. Ionophores
Reduced
methane
emissions
• increasing feed conversion efficiency
• selective reduction in acetate production
• inhibition of release of H2 from formate
• shift in fermentation pattern
• anti-protozoal effect
Eg: monensin and lasalocid
(Moss et al. 2000, Barman et al. 2001, Beauchemin et al. 2008)

61. • Dicarboxylic organic acids such as malate may alter rumen
fermentation in a manner similar to ionophores (Lopez et al)
• fumarate, a precursor of propionate depressed methane
production in vitro (Asanuma et al.).
• Malate, which is converted to propionate via fumarate, also
stimulated propionate production and inhibited
methanogenesis in vitro
Propionate enhancers

62. Reductive acetogenesis:
An alternative pathway for
hydrogen disposal
 addition of mucin or
amino acids
 by striving the inhibition
of rival methanogens
(Genthner et al.1981, Morvan et al. 1994, Fievez et al.2001, Cottle et al. 2011

63. • immunize animals against their own methanogens
• methanogen cell envelope having pseudomurein serves as the
interface between the organism and its rumen environment
• represents a key area for the identification of vaccine and
drug targets (Leahy et al. 2010)
• indirectly affects the activity of archea as they have a
commensal relationship with rumen protozoa
Immunization:

64. Limitations :
 Not effective
• Specific to particular archea (Wright et al. 2004, Clark et al. 2007)
 Immunization failure
 Passive immunization: using antibodies prepared from hen’s eggs
 Antibodies decreased methane production in vitro but the effect was
short-lived (Cook et al. 2008)
 If this proves successful, valuable tool for methane reductions as it
could be applied to a whole ruminant population

65. • In the rumen, bacterial viruses (bacteriophages or phages) are well
known having population density about >109 particles/ml fluid
and they attack a wide variety of bacterial hosts (Klieve and Swain
1993)
• Phage-like particles are known to infect Methanobrevibacter
smithii and Methanobacterium thermoautotrophicum (Nagle 1989)
• M. smithii strain PS is the host for a virus that has a morphology
identical to phages of the family Siphoviridae (Knox and Harris 1986)
• limitation : biocontrol agent is probably lack of universal
infectivity.
Phage therapy:

66. • Rumen ciliate protozoa are known to be endosymbiotically
associated with methanogens (Finlay et al.1994)
• protozoa-associated methanogens are accounted up to 37% of
total rumen methane emissions.
Defaunated animals produce less methane (Williams and Coleman 1992)
• shift of digestion from rumen to hind gut (Van Nevel and Demeyer
1996)
• the loss of methanogens associated with protozoa (Hegarty 1999)
• Defaunation methods are having various negatives either on the
rest of the rumen microbes or on the host itself (Williams and
Coleman 1997)
Defaunation:

67. Defaunation may depress fiber digestion, thus
complete elimination of protozoa (rather than
selective defaunation) is not recommended
• saponin containing plants - suppressing or
eliminating protozoa (Malik and Singhal 2008b)
saponins are differentially toxic to rumen protozoa -
presence of cholesterol in eukaryotic membranes but
not in prokaryotic (Kilta et al. 1996)

68. Disabling the protein binding:
 Methanogens associated with other ruminal organisms via
specific surface proteins
 Disabling these proteins or preventing their binding could
disrupt these interactions and upset their normal behaviour.
 Key genes and enzymes which may be potential targets
involved in the methanogensis pathway within the cell are the
possible vaccine targets Leahy et al. (2010).

79. Straws
Dry adult cattle can be maintained with
straw as a sole feed with small
quantities of protein supplements, but
extensive use is limited by factors like,
 High lignin & oxalic acid content
 Dustiness & reduced palatability
 Reduced calcium absorbability

80. Straw Treatment
• Alkali treatment:
1.25 % NaOH @ 1 Lt sol. /kg straw.
• Soaking straw in water:
Soaking 1 kg straw in 1 lit of water decrease dustiness.
• Impregnation of straw with urea - molasses:
Increase palatability.
• Ammonia treatment:
Treating straws with ammonia gas without adding water
increase nitrogen content.
