The Barred rock – Dual purpose This is a tail bird with a deep long square body. The barring (black parallel stripes of plumage) is uniform throughout the body with a grayish under colour. 5. New Hampshire red This is a hardy bird and an excellent layer which produces tinted eggs. It has a single comb of medium size. The flesh, feet and legs are yellow in colour.

Compare your answers with those given at the end of this unit.
You now know the various chicken breeds available in Kenya and their characteristics. Next we shall discuss incubation practices.
Section 3.2: Incubation
Incubation is the process of keeping eggs under favourable temperatures in order to promote embryonic growth and the hatching of young chicks. Before we look at the process of incubation, let us look at the composition of a chicken egg.
Composition of a Chicken Egg
A chicken egg is made up of various parts as shown in figure 3.5 below:
 The shell
 The shell membrane
 Albumen
 Chalazae
 Yolk.

The Shell
This forms 12% of the egg and is largely made up of calcium carbonate which
makes it hard. It protects the interior parts of the egg and has pores that allow
gaseous exchange.
Shell Membranes
This is the inner lining of the shell. It has 2 membranes that separate at the broad
end of the egg to form an air space.
Albumen (egg white)
The albumen makes up 55% of the egg. It is a jelly-like, colourless fluid when
fresh.
It surrounds the yolk and serves as a food reserve for the developing chick.
Chalazae
These are 2 twisted cords which hold the yolk from both ends of the egg.
If the chalazae is broken the yolk shakes and is displaced from its normal position.
Yolk
The yolk makes up 33% of the egg. It is yellow in colour and spherical in shape. It
has a germ spot which develops into a chick. A fertilized germ spot is called a
plastoderm while an unfertilized one is called a plastodisa. The yolk contains
food reserves for the developing chick and is rich in vitamins, fats, minerals and
protein.
Qualities of Eggs for Incubation
Eggs for incubation should have the following qualities:
 They should be fertilized
 They should be of medium size i.e. about 55-60gms in weight
 Should have smooth shells
 Oval shaped
 Not cracked
 Clean to ensure that pores are open

 Should not have abnormalities such as blood spots, meat spots, double yolk
etc.
 Should not be more than 5 days old.
Egg Candling
Egg candling is a method used to check eggs for fertility and determine which ones
will hatch into chicks. It involves observing an egg through light rays, see figure 3.7
for the candling technique.
Figure 3.7: Candling technique
Candling Method
As you can see from Figure 3.7, candling is a simple method which you can do at
home using the following procedure:
 Cut a small round hole on top of a cardboard box. The hole should be just
big enough to sit the pointed end of the egg
 Place a torch inside the cardboard box just under the hole
 Place the egg on the hole and turn on the light
 You will be able to see if the egg is fertile. A fertile egg has blood veins and a
black spot inside the egg. Figure 3.8 shows you the results of candling.

  • Pig industry sustains livelihoods of many families in Kenya. Pig rearing has been one of wellestablishedindustry in Kenya following growing export markets and increasing number of health conscious consumers. Pig production if efficiently managed has great potentials for increasing protein supply in Kenya. Smallholder pig farms in Tharaka-Nithi County have been facing varying and dismal profits. The main objective of this study will be to establish which institutional arrangements and management factors affect the profit efficiency of small-holder pig farmers in Tharaka-Nithi County. A multi-stage purposive sampling technique will be adopted to collect cross sectional data of eighty (80) smallholder pig farmers in Maara Constituency by the use of semi-structured interview schedules. The work will employ Data Envelopment Analysis to come up with profit efficiency rankings among the farmers and stochastic frontier profit function will be used to analyze the factors that affect profit efficiency. The data will be processed using STATA and DEA Frontier packages. The findings could be useful to the stakeholders of the pig industry sub sector to formulate policies pertaining to pig enterprise inputs, marketing issues and financial products and also can establish benchmarks which can be used as a package for enhancing and stabilizing profit efficiencies of smallholder pig farmers which in turn could help improve the Kenya economy. An Overview of Livestock Sub-sector in Kenya Perspectives, Opportunities and Innovations for Market Access for Market Access for Pastoral Producers Recent statistics point that the livestock sub-sector in Kenya accounts for approximately 10% of the National Gross Domestic Product (GDP). This is 30% of the agricultural GDP. It employs about 50% of the national agricultural workforce and about 90% of the ASAL workforce. 95% of ASAL household income comes from this sub-sector. This is despite the fact that the sector receives only 1 % of the total annual budget allocation. The livestock resource base is estimated at 60 million units comprising of 29 million indigenous and exotic chicken, 10 million beef cattle, 3 million dairy and dairy crosses, 9 million goats, 7 million sheep, 0.8 mi camels, 0.52 mi donkeys and 0.3 million pigs. (Strategy for Revitalizing Agriculture (SRA) 2003) Kenya is broadly self-sufficient in most livestock products but is a net importer of red meat mostly inform of on-the-hoof animals trekked across the porous boundaries of neighbouring countries- Somalia, Ethiopia, Sudan, Uganda and Tanzania. Livestock supply in Kenya results from a complex set of interactions between Kenya and its neighbours and the traditional Middle East market and their respective livestock populations, demand and market prices. Kenya is part of a regional market where livestock flow according to markets and price differentials in a liberalized system throughout the region as a whole and where Nairobi represents a focus of demand for the region Supply of red-meat from domestic cattle, shoats and camels falls short of demand, and is almost permanently augmented by a traditional livestock trade drawn in from neighbouring countries, especially Somalia, Tanzania, Sudan and Ethiopia in varying quantities according to demand, which maintains a supply/demand [1.6MB]SIJAAMINI WEMA SEPETU ANACHOKIFAYA HAPO KWENYE HII VIDEO BOFYA UONE
