Jurnal Veteriner is a scientific journal encompassing animal science aspects, published since 2000, and until now is consistently published four times a year in March, June, September, and December by Faculty of Veterinary Medicine, Udayana University, associated with Association of Veterinarian Indonesia. Jurnal Veteriner is a peer reviewed journal that has been accredited by Directorate General of Research and Development Strengthening, Ministry of Research, Technology and Higher Education of the Republic of Indonesia since 2002.

Jurnal Veteriner has been indexed and abstracted in  Clarivate Analytics products (formerly Thomson Reuters), DOAJ, CABI, EBSCO, Science and Technology Index (SINTA), Garba Rujukan Digital (GARUDA), Google Scholar, and other scientific databases.  Jurnal Veteriner also used Similarity Check to prevent any suspected plagiarism in the manuscripts.

Jurnal Veteriner receives manuscripts cover a broad range of research topics in tropical veterinary medicine and tropical animal sciences: anatomy, histology, pathology, virology, bacteriology, pharmacology, mycology, clinical sciences, genetics, reproduction, physiology, biochemistry, nutrition, animal products, biotechnology, behaviour, welfare, livestock farming system, socio-economic, wild life and policy.

Proses Spermatogenesis

Paparan Formalin Menghambat Proses Spermatogenesis pada Mencit

Formaldehyde is one of the exogenous free radicals. During formaldehyde exposure, there will be morefree radical or reactive oxygen compound formed through electron transport chain. Excessive reactiveoxygen compound triggers the process of lipid peroxide reaction in the membrane of spermatozoa cell. Theaims of this study were to find out that formaldehyde exposure caused abnormalities in the number of thenumber of spermatogonium type A, spermatogonium type Pachytene, 7th spermatid and 16th spermatid inspermatogenesis process.This study was experimentally and randomly pretested-posttested- with controlgroup design. The samples of this study were adult male mice strain Balb-C (age 2-3 months) with thefollowing criteria: body weight between 22-25 grams and healthy. Randomly, 48 mice were divided intothree groups, were control group, the first treatment group and the second treatment group. Prior to thetreatment, were taken a half from each group for the pre-test, by preparing microscopic preparation testicleand examination was performed to the total spermatogenic cells. The rests of the mice were used as posttestexamination after 35 days treatment. On the 36th day, all the rest mice were necropsied for microscopictesticle preparation. The result of this study showed that the formaldehyde exposure caused significantlydecrease in the number of spermatogenic cells (p<0,05), the average of type A spermatogonium cells atcontrol group, 1st treatment group and 2nd treatment group were 39,90±0,51; 20,42±0,72; 15,65±0,88respectively; spermatogonium type Pachytene were 48,47±1,28; 32,60±3,06; 23,14±3,16 respectively; 7thspermatid were 97,47±5,28; 39,98±4,28; 30,36±2,96 respectively and16th spermatid were 73,08±4,05;21,70±1,70; 16,38±1 respectively.It can be concluded that the formaldehyde exposure decreased the amountof spermatogenic cells. The result of this study is expected to be used as the baseline for further study inorder to measure formaldehyde content as a free radical in testicle
