چکیده

In this study, 73 non-pregnant and clinically healthy and lactating holstein cows without any clinical signs, and with a mean parity of 3.2 ± 1.4, days in milk at the beginning of study 110 ± 20 days, body condition scour (bcs) of about 3.2 ± 0.3, and milk production rate of 48± 10 kg were selected and randomly placed in two treatment and control groups. in the treatment group (n=36), arginine (155 μmol / kg body weight) was injected once every 8 hours a day for 6 days, and in the control group (n=37) saline solution (0.11 ml/kg body weight, once every 8 hours a day) was injected for 6 days. the results showed that there was no difference between the treatment and the controle group in terms of milk production (38.5 and 36 kg, p=0.3), fat (3.7 and 3.8%, p=0.8) and protein (3.1 and 3.1%, p=0.5) levels. it was concluded from this study that the use of arginine after the peak of milk production could not increase the fat, protein, and production levels of milk.

Abstract
