	abstract = {The rate at which the Na:K ratio of parotid saliva changes with changes in Na intake has been determined in lactating dairy cows. The salivary Na:K ratio of cows with an already marginal Na status fell immediately the animals were transferred to a Na deficient diet. Similarly the Na:K ratio of Na deficient cows incr3eased within days of Na supplementation reaching maximum levels after 2 weeks. The mean Na:K ratio for fully sodium replete cows was about 24 to 28:1, but there was considerable variation in the values for individual animals.},
