Monitoring of Environmental Parameters
Environmental parameters such as humidity and temperature outside and inside the husbandry were
monitored as these would affect the welfare of the birds.
Relative Humidity Variations
The relative humidity within and outside the integrated aquaculture in the morning, afternoon and
evening is as shown in the graphs in Fig.12, 13, and 14. The graphs indicated that the relative humidity
within the integrated aquaculture in most cases was higher than that of the outside. In the morning
there was a marked difference between the indoor and outdoor relative humidity. The relative humidity
outside varies from 77.7% to 96.8% while the relative humidity inside varies from 83.6% to 98.8%.
The increase in relative humidity resulted from evaporation of water from the pond surface. This is a
very high relative humidity and could influence the growth of disease causing micro-organisms, which
could adversely affect the well being of the birds. However, no incidence of disease was recorded
throughout the period of the experiment because of lower temperature and increased management
practices. Since a battery cage system was used for the birds, it was not possible for the birds to
contaminate the feed and the water.
