Water salinity and air temperature on quail production and organ characteristics

ABSTRACT The supply of salt water in the semiarid region is a recurrent practice, as there severe shortage for use animal consumption. Thus, most times offered to birds can contain salts above recommended amount. present study aimed evaluate production performance and morphometry organs Japanese quails they were supplied with drinking different concentrations sodium chloride, while being maintained comfort under thermal stress. received increasing electrical conductivity (1.5, 3.0, 4.5 6.0 dS m-1) kept climate chamber at thermoneutral air temperature (24 °C) stress (32 °C), distributed completely randomized design 2 × 4 factorial scheme. Water conductivities did not affect birds, except weight gizzard, which showed an linear effect increased. At temperature, was reduction feed intake, egg mass, conversion per dozen eggs, but no on weights heart, liver gizzard. phase consume up m-1, showing good without compromising organ morphometry.
