Feed for poultry may be given in the form of
Mash
Pellets
Crumbles
Complete Feed(A mix of individual feed ingredients , ground)
Mash (dry)Additional of water
Wet mash Pellets ( 3 to5mm)For chicks above 3 weeks of age
Crumbs or crumblesFor chicks up to 3 weeks of age
Mash feed is subjected to temperature and steam and forced to pass through a die made up of holes
Most common method practiced in our country
Mash is a form of a complete feed that is finely ground and mixed so that birds cannot easily separate out ingredients.
provides a well balanced diet.
Simple manufacturing procedure is needed for mash form of feed.
ground feed is not so palatable and does not retain their nutritive value so well as ungrounded feed
Mash
Advantages of pellets
Reduction in dustiness of feed
Higher nutrient density
Prevention of selective feeding
Higher palatability and increase in feed intake
Destruction of pathogenic micro organisms
Increased digestability of certain nutrients due to cooking effect
Improved growth and feed conversion
Uniformity in production
Maintaining feed intake in heat stress
Easy handling of feed
Suitability to mechanical conveyance and storage
Reduced in segregation of high density ingredients and micro nutrients
Reduced wastage of feed
Disadvantages cost of pellets is higher
Destruction of vitamins and certain feed additives
Susceptibility to mycotoxins if properly not dried
Increase water intake and wet litter problem
Increase cannibalismNo further mixing of any ingredient or additive.
crumblesCrushed pellets used to feed
younger birds and these are known as crumbles
Cafeteria systemChoice system of feeding buffet
type feedingChoice betweenEnergy sourcesProtein sources along with
vitamins and mineralsCalcium in granular form
Sex separate feedingAs per BIS latest standards,
broiler and layer males fed with low protein diet having 15 and 16% protein respectively,
High protein diet will effect sperm quality.
Female broiler and layer breeders—16 &17% CP
High levels of vit E (40mg/kg) for males
Ca—3.5% for female
The male and female feeds are offered separate feed hoppers in slat and deep litter system.
In cage system can be followed accurately
On floor, feed is provided for males in feeding placed at higher level to which the female feeders can not reach.
Males can not reach female feeders as the partitions of the feeders are smallar
Economizing Feed costFormulating least cost diets to
meet the nutrient requirements
- Specific soft ware programme
Inclusion of un conventional feed ingredients
- Less expensive
- Limitations in their inclusion levels
Home feed mixing
1.Procurement of feed ingredients in bulk
at economic rates.2.Quality evaluation in the laboratory
available with them3.Formulation of diets by experienced
nutritionist4.Processing and mixing in the efficient
equipment
5. Quality evaluation of finished product
6. Storage and transport of feed ingredients and feed in a scientific manner
( Small farmers are adviced to procure feed ingredients from reliable feed manfactures)
Reducing feed wastageFormulation of diets to meet the
nutrient requirementsProper feed processing
(grinding,mixing)Procuring quality feed eqipmentPlacing sufficient No. of feedersProper placement of feedersProper placement of feed in feedersDebeaking of chickenControl of rodents
Procuring quality feed equipmentChickens having habit of scratching and
billing of feed out of the feeder.
The feeders either tubular or linear. In both cases, the design must be to avoid feed wastage.
Proper size of feeders, adequate but not excessive slope from center to periphery of pan in tubular feeders.
sufficient and raised lip(450) of the room of feeders help in prevention of feed wastage from feeders.
Number of feeders
Sufficient number of feeders ensures
adequate feed intake
uniform growth
prevents possibly cannibalism
over crowding of chickens near feeder when feed is placed.
Placement of feeders
Chicken take feed properly when feeders are distributed uniformly in a house.
Feeders may be placed at a level height so that the height of lip of feeder is at the level of the back of the bird.
This prevents easy billing of feed out of feeder.
Placement of feed in feeders
Placement of more than one-third feed in feeder results in wastage.
Feeders may be filled, if necessary, more frequently.
At least once a week, feeders may be cleaned to remove caked up feed.
Debeaking of chicken
Debeaking prevents or reduces billing of feed from feeders.
Control of rodents (rats and mice)
Rats and mice are common in poultry houses. A pair of rats produces 3-6 litter. With in a year, about
15, 000 rats can be multiplied from a single pair.
Economical losses to poultry farmers due to rodents
i. Eat feed: 30g/day/ rat 2-3g/day/mouseii. Carrier of diseasesiii.Contaminate feed with feces (40
droppings/rat/day)
Control methods:Environment control(rat proof)
Chemical control ( use safe rodenticides regularly)
Trapping/ Hunting of rats
Clean premises
Clean poultry houses, feed godown and stores
Pet cat in the farm
Feed storage
Feed from point of manufacture until offered to birds has to be stored.
During storage, the following effects may occur.
Moisture pick up from environment
Nutrient destruction
Oxidation of nutrients
Insect infestation
Proper storage involves the following.
Store has to be constructed away from poultry houses and manure pits
Store has to be rat proof and damp proof
Prevent wild bird entry
Ventilation and light must be adequate
Use disinfectant tub at the entrance of store
Prevent people working in poultry houses from entering into the store house
Maintain feed store clean
Fumigate store with potassium permanganate and formalin.
Fumigate with insecticide
Spray cupper sulphate or any disinfectant on the empty floors inside the store.
Store bags of feed or feed ingredients on wooden or iron pallats instead on floor directly.
Duration of storage of feed Purchase and stock feed for 1-2 weeks during rainy season and 3-4 weeks during winter and summer seasons.
Fresh feed always better than old one.
Do not use fermented, damp/ wet feed under any condition.
Never use infected or caked feed.
