1.3 The business of poultry farming
There are many small farmers that are making money out of raising meat birds (broilers) in developing countries. They buy day-old chicks from chick breeders who may be far away and usually sell them live after 7-8 weeks. They also buy their feed in from the nearest feed mill. This may be a long way away and this will mean that feed is expensive. They will need to sell their broilers at a high price.
Because of long distances, and because of unreliable transport, sometimes some chicks arrive sick or dead. If there are enough producers, they can form a co-operative and may be able to establish a small poultry hatchery (see section 14). This will help to make chicken meat production sustainable. A depot can be set up to purchase and store large amounts of feed to sell to the poultry keepers at a cheaper price. Egg producers may also benefit from such an arrangement.
Producing eggs is more difficult than broilers. The day-old chicks are very expensive and you have to wait more than 18 weeks before the hen will lay an egg. They are not easy to rear as they must be grown slowly and according to a plan. They also need to have good housing and nest boxes so there is a higher initial capital cost than growing meat birds. There is usually a shortage of eggs in villages and they may have to be transported long distances to customers so there is often great opportunity to farm commercial hens starting with a few and then expanding. The customer can purchase a few eggs at a time so the financial outlay is less than buying a broiler chicken.

There may be opportunity for commercial egg production by starting in a small way. We will talk about this later
When you finish this course, we plan to be able to help you with your chicks, their feed supply and the trainers will be able to give you advice. You will see during the course that there are different ways to keep laying hens and broiler chickens

1.4 Background information
You will need to look at all aspects of commercial poultry production before you decide to become a poultry farmer
This means that you will have to seek out information in a survey
On the basis of this information you will make a business plan. This will tell you how much money you can expect to make (or lose) each year
A good business plan will allow you to go to the bank to borrow money to get your commercial poultry farm started
You will not start with a feasibility study now but towards the end of the course when you will know more about poultry and what farming poultry entails. But you should look at this from time to time throughout the course at the questions that need to be answered so that you can gather the necessary information.

2. POULTRY BREEDS
There are many different breeds of chickens. We will only mention here those that have commercial potential (meat and/or eggs).
Dual Purpose. These are used to produce both meat and eggs such as Rhode Island Reds or Plymouth Rock.
Today, for large – scale commercial production they do not produce enough eggs
nor do they grow fast enough for meat production
they eat too much feed
they are not very efficient in converting feed to eggs and meat
Dual purpose breeds may have a role to play where it is not possible to get better breeds or conditions are not ideal or feed is not of the best quality
Special Breeds. These have been selected for egg production
the White Leghorn was very popular for many years
it has a small body (1.5 kg) and lays many white eggs
the Black Australorp is another popular breed
it is very docile (quiet) and lays a tinted (light brown) egg
it is medium-heavy body weight (2.2 kg) and therefore eats quite a lot of feed
it is good for free-range (out doors) conditions as it is not flighty
7. HEALTH AND DISEASE PREVENTION
Chickens are fragile and can get sick very easily especially when young
There are two major sources of disease.
Diet if not correctly formulated can result in the bird getting a metabolic disease due to a nutrient deficiency (vitamins or minerals) in the diet
Other diseases are caused by minute organisms called bacteria and viruses. It is often necessary to treat the chicks as soon as they hatch with a vaccine which allows them to resist the disease if it occurs. This is normally done at the hatchery. Newcastle disease is present in many countries and chickens need to be vaccinated more than once (see section 7.1)
24
Remember that “prevention is better than cure!”
Many diseases can be prevented by keeping your poultry house very clean
Overcrowding of birds can cause disease
Do not allow other poultry on to your farm (e.g. neighbour’s scavenging chickens)
Do not allow other poultry farmers to enter your shed
Place a foot bath with a disinfectant in it or limestone outside the door of your poultry house
Have a special pair of boots/shoes that you will use only when you are working in your poultry house
Leave sufficient time between batches of birds to clean the house and get rid of diseases that need to have a bird (host) to survive
Remove old litter, dirty bags and contaminated rubbish and dump them far away but in a responsible place that will not contaminate the environment
Discard damp, old feed. It can grow mould which can produce toxins. They can kill or make your chickens sick
All in-all out systems in which all birds are the same age help to reduce disease out breaks
25
External parasites such as mites, lice and fleas can make your poultry feel uncomfortable. This will affect their growth rate and egg production
Insecticides are used to treat the infected birds. A dust bath will also help to reduce these external parasites
Internal parasites such as different worms and minute protozoa causing coccidiosis can be prevented by medication
This is done routinely by adding a coccidiostat to the mixed feed for broilers
Remove immediately sick birds and bury dead birds.
Never eat or sell sick birds; they will make your family and others ill
7.1 Newcastle disease
There are two diseases that are particularly dangerous in many low-income countries. Newcastle disease (ND) is endemic (always there) in many countries and becomes active particularly at the start of the wet season. It can wipe out entire village flocks although a few individual birds often do survive. There are now ND vaccines that will withstand the heat for a short period (thermostable) of time. Vaccination is most effective by eye drop and birds should be vaccinated a month before expected outbreaks by a trained person. There is also a need to treat the birds at intervals through out their life. This is a specialised area and the poultry keeper will need help from experts but it is well worth the effort and the vaccine is not expensive.
26
7.2 Avian influenza
The H5N1 strain of highly pathogenic avian influenza (bird ’flu) is particularly dangerous not only because it can infect different poultry species and wild birds but it can also kill humans. Village poultry are especially at risk because they are outside and may be in contact with wild birds and other poultry species (ducks, geese). The disease spreads rapidly through the poultry flock.
The virus can be spread by eating infected birds and can kill the consumer particularly if she/he is young. Household poultry keepers should keep themselves informed about the situation in relation to bird ‘flu as it often appears at particular times in the year.
EXERCISE
We will now discuss the two specialised areas of commercial (intensive) poultry production: broiler (meat) production first and then egg production.

8. COMMERCIAL BROILER MEAT PRODUCTION
Chicken meat is very popular throughout the world. It is seen as a healthy meat low in fat and rich in protein (lean meat). It is a meal for a family so you don’t need a refrigerator
To prepare for the chicks’ arrival it is best that you have a time plan or schedule
the house will be thoroughly cleaned and disinfected
shavings or litter on the floor
the brooder surrounds in place
the brooder heater checked and adjusted (if there is one)
feeders and drinkers in place. Chicks usually look for water first.
a supply of a small amount of starter feed is scattered on paper on the floor of the brooder so that the chicks can start to eat
28
For the first 7-10 days the chicks will be brooded (see section 5.) Broiler chickens can grow very fast but only when well looked after and given good feed
After 3 weeks of age when the house temperature is less than 28–30 oC they grow best. In the tropics, the temperature is normally above 30 oC in the day time so they will grow a bit slower than usual
Some chickens will die in the first week particularly those that are small and weak. You must remove and bury them immediately
You can expect to lose at least 4 - 5 chicks out of 100 in the first 3 weeks. Another 2 may die later. Mortality can be much higher especially if management and housing conditions are poor. Some broilers, as they get older, may become lame and are unable to walk and get to the feeders. This is partly a breeding problem but may be reduced by slowing growth in the second week for about a week by limiting feed intake.
29
Ideally, chicks should be given a bought formulated diet. A commercial starter diet should be purchased and fed for at least the first 10 days because they need to get off to a good start
They will have eaten only about 250 g of feed during this time. This will cost you less than 25 ¢/bird
A grower diet will then be introduced by mixing what remains of the starter diet with the same amount of the grower diet. This will mean that they can adjust easily to the new feed
When the mixture is finished, chicks will be on the grower feed only
Check chicks several times a day to see that they are comfortable and have feed and water
Check your chickens frequently. They do not like it too warm.
It will be helpful if you have weighing scales so that you can weigh feed given to the chickens and get the live weight of a sample of 10 birds every 2 weeks caught with a simple leg catcher.
