Abstract

This study was conducted to investigate the effects of tryptophan (Trp) and rumen-protected tryptophan (RPTrp) supplementations in diet on lactation performance, plasma indexes and milk melatonin (MLT) content of dairy cows. Thirty healthy Holstein dairy cows at 3 to 5 years of age, 2 to 3 parities, (180±46) d of lactation days were selected and randomly divided into 3 groups, which were control group, trial groups Ⅰ and Ⅱ. Cows in control group was fed a total mixed ration (TMR), and trial groups Ⅰ and Ⅱ were supplemented with 100 g/(d·head) Trp and 220 g/(d·head) RPTrp[L-tryptophan content was over 45%] based on control group, respectively. The pre-trial lasted for 7 days, and the trial lasted for 60 days. The results showed as follows:1) Compared with control group, milk yield in trial groups Ⅰ and Ⅱ was increased by 11.78% (P<0.05) and 17.19% (P<0.01), respectively; lactose yield in trial groups Ⅰ and Ⅱ was significantly increased (P<0.01). 2) Compared with control group, plasma growth hormone (GH) content at 14:00 and 22:00 in trial groups Ⅰ and Ⅱ was significantly increased(P<0.01); at 14:00, plasma Trp content in trial group Ⅱ was significantly increased (P<0.01), but there was no significantly difference of plasma MLT content among groups (P>0.05); at 22:00, plasma Trp (P<0.01) and MLT contents (P<0.05) in trial group Ⅱ were significantly increased; in trial group Ⅰ, plasma Trp, 5-hydroxytryptamine (5-HT) and MLT contents were not significantly changed both at 14:00 and 22:00 (P>0.05). 3) Compared with control group, at 05:00, milk MLT content in trial group Ⅱ was significantly increased (P<0.01); at 18:00, there was no significant difference of milk MLT content among groups (P>0.05). 4) Compared with control group, plasma total antioxidant capacity (T-AOC) in trial group Ⅰ was significantly increased(P<0.05); plasma glutathione peroxidase (GSH-Px) activity in trial group Ⅱ was significantly increased(P<0.01); plasma superoxide dismutase (SOD) activity in trial groups Ⅰ and Ⅱ was significantly increased (P<0.01); plasma malondialdehyde (MDA) in trial group Ⅱ was significantly reduced (P<0.01). In conclusion, supplementation of Trp[100 g/(d·head)] and RPTrp[220 g/(d·head),] increases milk yield, plasma GH content and antioxidant capacity of Holstein dairy cows, and RPTrp shows better effect; supplement of RPTrp[220 g/(d·head)] elevated plasma Trp content and plasma MLT contents at night of dairy cows, and hence increase MLT content in milk at the night.
