THE USE OF CITRONELLA OIL FEED ADDITIVES OF A FORTIFYING FEED MIXTURE FOR PHYSIOLOGICAL DESCRIPTION OF BEEF CATTLE BLOOD

The citronella oil feed additive is able to increase the immunity of ruminants and poultry. Because citronella essential oil contains bioactive compounds which are able to kill bacteria, help absorb protein as a material for producing immunoglobulins, immune substances for livestock. This study aims to determine the effect of giving premix supplements with essential oils added as a concentrate feed mixture on the physiological picture of beef cattle's blood. The material used was 14 Simental cattle, with an age range of 1-1.5 years. The feed consists of 60% elephant grass forage and 40% concentrate consisting of (pollard, rice bran, corn tumps), by adding 2% premix as a feed mixture. Feeding was given for one month and the conditions were compared before and after giving the citronella oil additive. The method used was treatment by measuring the condition of the cows before and after giving them. Variables observed included levels of physiological blood indicators (leukocytes, platelets, erythrocytes and hemoglobin) of beef cattle. Data analysis uses quantitative descriptive analysis methods. The results of the study showed 1. The red blood cell level before being given the treatment feed was 4.81 x 106 and the average value after being given the treatment feed was 4.68 x 106 uL. The level was 15.10 g/dL. Platelet levels before being given the treatment feed were around 953.36 x 103 and after giving the treatment feed had a higher value, namely 1463.86 x 103.uL.
