Lysine and methionine which are limiting amino acids of dairy cows are administered to dairy cows to decrease the BUN value that has an adverse effect on the conception rate and to increase the blood glucose required to improve the energy balance, that alanine and glutamine are administered to dairy cows to increase the blood glucose and to improve the liver function, and that the use of these amino acids is effective for keeping good conditions of dairy cows, allowing earlier arrival of initial estrus without any stress, improving the mating conception rate and decreasing the non-conception rate.

A method for supplementing the amino acid levels in ruminants is provided where rumen-protected amino acids, particularly lysine and/or methionine, are used to supplement ruminant feed.
