Abstract

The enzyme monoamine oxidase-A (MAO-A) is a compound that can break down serotonin. So if the level of monoamine oxidase-A in the blood is high, the level of serotonin in the blood will be low. It is known that the enzyme monoamine oxidase-A affects dog aggression. How exactly is the picture of monoamine oxidase-A in the blood of pet dogs has not been widely revealed. The purpose of this study was to determine the levels of monoamine oxidase-A in Kintamani pet dogs. Kintamani dogs are a native Indonesian dog breed found in Kintamani Village, Bali Province, Indonesia. The study used forty dogs, 15 male dogs and 15 female dogs and 10 lactating dogs. The method used in this study was the observation and cross-sectional sampling method and monoamine oxidase-A levels were determined using the elisa technique. The results showed that the average levels of monoamine oxidase-A in male Kintamani dogs (ng/ml) were 3.54 ± 1.9, females 4.85 ± 1.7 and lactating dogs 3.15 ± 2.23. The conclusion that monoamine oxidase-A level depending sex and lactating. The levels of monoamine oxidase in male dogs are lower than in female and lactating dogs.

Abstract

Foot and mouth disease remains one of the most economically important infectious diseases in production animals. This disease can have many consequences, including reduced productivity, limited market access, and loss of livestock herds. Foot and Mouth Disease (FMD) vaccination is a crucial preventive measure to maintain livestock health, but its impact on the fertility performance of Bali cattle requires further investigation. This study aimed to analyze the association between FMD vaccination and the fertility performance of Bali cattle in Badung Regency. The study was conducted on 390 vaccinated Bali cattle, with fertility parameters observed including abortion, retained placenta, and repeat breeding rates. The results showed an abortion rate of 6.4% and a repeat breeding rate of 34.4%. Statistical analysis using the Test of Between-Subject Effects revealed a significance value of P<0.05, indicating a significant association between FMD vaccination and the fertility performance of Bali cattle. These findings provide important insights into reproductive management and highlight the need to consider vaccination aspects in cattle husbandry programs.
