Mortality rate was found to have a negative<br />

Feed conversion efficiency had a positive and<br />

non-significant regression with education level<br />

of farmers and staff expertise but it was negative<br />

and non-significant with chicks quality. Average<br />

total production was found to have a positive<br />

significant regression on educational level of<br />

farmers and staff expertise but it was negative<br />

and non-significant with chicks quality (table 3).<br />

6. Technical specifications of broiler houses<br />

One of the objectives of this study is<br />

searching for the ideal specifications for the<br />

houses according to North & Bell 4 , to provide<br />

warmth for broilers during cold weather and to<br />

provide proper cooling in hot weather. It has<br />

been observed that most of fields were similar to<br />

the closed type, whose ventilation depends on<br />

the movement of the free open air only.<br />

<strong>The</strong> most important specifications for broiler<br />

houses have been researched in the studied<br />

sample like house orientation, width & height of<br />

the house and thermal insulation in the field.<br />

It is always advised that the house orientation<br />

should be east-west 5 , which reduces the effect of<br />

high summer temperature 6 . <strong>The</strong> results showed<br />

that (60 %) of the total number of the houses has<br />

been brought to the longitudinal axis east-west.<br />

It is known that the temperature may rise during<br />

the summer in some areas of study, thus it could<br />

be higher than (40ºc) during the day time, which<br />

is higher than the temperature required for<br />

optimal production in poultry, which is ranged<br />

between (18-22ºc), (Austic & Nesheim, 2005).<br />

<strong>The</strong> width of the house in semi-closed system<br />

should not be more than (12 m) (Ernst, 1995),<br />

and it is preferred that the width would be<br />

between (10-11 m). <strong>The</strong> study has shown that<br />

(70 %) of the total houses are built with the<br />

width of (10-12 m).<br />
