Summary

Statistical analyses were carried out on the data obtained, under strictly controlled conditions in metabolism stalls, from 219 adult non-pregnant dry cows fed on seventyone different rations. The authors have calculated and studied the correlations between total water intake, faecal and urinary water losses, absorbed and available water, and the seventy-five other factors which were analysed in each of the seventy-one rations. Total water intake closely correlated with the dry-matter intake and also with the dry-matter content of the diet; forages with high moisture content enhance the total water intake which is also significantly correlated to the intake of nitrogen, fat and some mineral elements.

Total water intake closely correlated with the dry-matter intake and also with the dry-matter content of the diet; forages with high moisture content enhance the total water intake which is also significantly correlated to the intake of nitrogen, fat and some mineral elements.

Faecal water losses are strongly correlated with the dry-matter intake and on the faecal dry matter. Moisture content of the diet has no significant effect but increasing pentosans and crude-fibre intake enhance the losses.

Urinary water excretion is closely related to the amount of absorbed water and to the dry-matter content of the diet; a highly significant correlation also exists between urinary water and urinary nitrogen and potassium. The amount of water excreted in the urine may affect the utilization of digestible nitrogen and potassium.

Available water is increased logarithmically when total water intake rises arithmetically. Feeds with high moisture content thus enhance the amount of available water.
