title: The evaluation of suitable waterers for broiler chicks reared under hot summer conditions.
abstract: In four groups of 150 broiler chicks each the suitability of different waterers (ordinary pans I, clay II, continuous folowing III, automatic trough waterers IV) was tested between 0 and 8 weeks at daily maximum temperatures not below 40 degrees C, and their effect was compared on the growth and the feed requirements. The eight-week weights were 1105 g (I), 1114 G (II), 1194 g (III), and 1160 g (IV). They were significantly higher in groups III and IV, which is attributed to the lower (2--3 degrees C) water temperatures. The feed efficiency was between 2.01 and 2.07 kg/per kg liveweight.
