Abstract

This experiment was conducted to determine the effects of cysteamine (CS) on microbial protein production, milk performance and nitrogen excretion. Forty Holstein lactating cows with similar age, body weight, milk yield and lactation stage [(135±15) d] were divided into 4 groups. The supplemental level of CS in control group, test groups 1, 2 and 3 was 0, 15, 20 and 25 g/(d·head), respectively. The pretest lasted for 14 days, and the test lasted for 56 days. The results showed as follows: 1) ruminal microbial protein production in test groups was significantly increased by 27.27%, 66.56% and 55.42% compared with that in control group (P<0.05 or P<0.01). 2) The cows in test groups 1, 2 and 3 had 18.97%, 19.58% and 11.25% greater daily yields of milk than those cows in the control group (P<0.05). 3) CS could significantly increase milk fat percentage and milk protein percentage (P<0.05 or P<0.01), but significantly reduced milk somatic cell count (P<0.05), especially the test group 2. 4) Compared with control group, total nitrogen excretion in test groups was significantly reduced (P<0.01), and was reduced by 16.24%, 22.66% and 9.92% in test groups 1, 2 and 3, respectively. Based on the data of ruminal microbial protein production, milk yield, milk composition content and nitrogen excretion indices, it can be concluded that the suitable supplemental level of CS is 20 g/(d·head)in dairy cows under the condition in the present study.

Key words： cysteamine; microbial protein production; milk performance; nitrogen excretion
