Abstract
This study was conducted to assess the effect of two types of ropes that farmers use for handling of their cows as agricultural practices, on the levels of blood serum cortisol as an indicator of stress and its effect on milk yield in dairy cattle. The study was conducted on 20 Holstein-Friesian crossbred cows of age 21 to 30 months. The animals were divided into two groups of 10 each. In the first group (P1) a local nose rope (telusuk) and in the second group (P2) halter rope were used for handling the animals. Blood cortisol values in the two groups showed significant differences (p<0.05). The milk yield in P2 was greater than P1 (p<0.05). Usage of telusuk rope can increase blood cortisol serum levels and reduce milk yield in dairy cattle.
