Abstract
The existence of statistically significant differences of water ingestion among and within poultry strains selected for high egg production as well as the existence of a positive statistical correlation between water ingestion and egg production were demonstrated by Favret et al. (1967).The following study had as its principal objective an analysis of the diurnal fluctuations of water ingestion in both sexes, and in the particular case of females to relate at a physiological level the time of oviposition and water metabolism. In this experiment 25 males and 35 females, both 10 months old, from a Single Comb White Leghorn line were utilized.The birds were individually caged at random. Each cage was equipped with individual food and water supply, the latter contained in a graduated glass container with a reduced liquid surface to minimize water evaporation. The experiment was carried out at Castelar, Argentina, during October (spring time) and …
