An overview histological of arteries, liver and intestine of male rabbits fed commercial cod liver oil supplementation

The long-term goal of this study is to improve the productivity of local rabbits. The specific target to be achieved is to improve the health of the rabbits through observing the histological features of arteries, liver and intestine of male rabbits after being given commercial feed supplemented with cod liver oil. To achieve these objectives, the method used is to create a feed formula that is rich in unsaturated fatty acids. It is expected that the provision of additional feed in the form of cod liver oil in commercial feed can improve the health of male rabbits. The experimental design used was a Completely Randomized Design (CRD) with four feed treatments, namely commercial feed without cod liver oil (P0) as a control, commercial feed supplemented with cod liver oil 3% (P1), commercial feed supplemented with cod liver oil 4.5% (P2), and commercial feed supplemented with cod liver oil 6% (P3). Each treatment consisted of five male rabbits as replications and the treatment was given from rabbits aged 3 months to 5 months. The parameters observed were arterial histology (intima tunica, media tunica, tunica adventisia), liver (central vein, sinusoid, hepatocytes), and intestine (mucusae, muscularis, serous) male rabbits. The data obtained were analyzed descriptively. After completing the research the research results will be published in scientific journals. The targeted scientific journals are Sinta 3 accredited journals (Journal of Biology or Udayana University's Symbiosis Journal). This is in line with the UNUD strategic plan, that the lead researcher is required to submit research outcomes related to the proposed research with the specified requirements.
