Abstract
A low cost kerosine fired incubator with heating from
below was developed.
Various methods of internal temperature control inside
the incubator were explored. Airtight sealed diaphramic
control was not possible due to the closeness of the
solubility index of the volatile liguids and locally available
adhesives.
The sensitivity of the bimetallic strip was low in the
temperature range of the incubator. (35°C - 39°C)
An electromechanical method of temperature control using
electromagnet was designed and applied to circumvent the
above problems.
The highest average daily dry bulb temperature value
inside the incubator was 38°C while the lowest value was 35°C
during the period of incubation.
The highest average daily dry bulb temperature inside the
room was 31°C while the lowest was 23°C.
The high relative humidity value obtained for the period
of incubation was 60% while the lowest value was 45%.
Relative humidity was negatively related to the incubator
temperature while the room temperature was positively related
to the incubator temperature.
Analysis shows that there was no statistically
significant linear relationship between the incubator
temperature and the room temperature at 5% level of
significance.
Also there was no statistically linear relationship
between the incubator humidity and the room temperature at 5%
level of significance. And there was no statistically
significant relationship between the incubator temperature,
the room humidity and the room temperature at 5% level of
significance.
The hatching result gave a hatchability of 86%, 63% and
57% for group I, II, and III respectively, for the third
experiment which show that the hatchability decreased with the
days of storage before incubation.
