| Outline of Final Research Achievements |
The present study was conducted in preparation for developing technologies of farm animal feeding management by using new functional feedstuff. The diet is processed into escaping the degradation by ruminal microbes. The single evening feeding of the rumen-protected Tryptophan (amino acid of 5-HT and melatonin precursor), or the rumen-protected Tryptophan plus glucose to dairy calves suppressed cortisol secretion under condition of acute stress, and increased secretions of melatonin and growth hormone. In addition, the long-term evening feeding of the diet induced an enhancement of their daily gain.
