Abstract

Lactic acid bacteria are facultative anaerobic bacteria that can live in the digestive tract of animals and humans. Lactic acid bacteria have been used as a culture of fermentation, food preservatives, and food probiotics because it has antimicrobial activity and food spoilage. Antimicrobial compounds produced by lactic acid bacteria include the production of lactic acid and pH reduction, the production of acetic acid, diacetyl, hydrogen peroxide, carbon dioxide, and bacteriocin. The purpose of this literature study was to find out the metabolite compounds produced in the fermentation process of lactic acid bacteria and analyze the use of metabolite compounds produced from lactic acid bacteria. This literature study was obtained from searching and collecting some various sources using the Mendeley and Google Scholar applications. 67 libraries were obtained and after being analyzed and evaluated, there were some fermented lactic acid metabolite bacteria obtained including lactic acid, acetic acid, and propionic acid, hydrogen peroxide, carbon dioxide, diacetyl, and bacteriocin. Whereas the use of metabolite compounds produced from lactic acid bacteria can be used as metabolic compounds that are antimicrobial, immunomodulatory, and in optimizing nutrient absorption.

Abstract

Green junglefowl (Gallus varius) is one of the endemic fowl in Indonesia. Testes are reproductive organs that play an important role in spermatogenesis. This study aims to describe the anatomical morphology and histology of the green junglefowl testes. The sample is 3 pairs of testes collected from 3 adult male green junglefowl from Alor Island with body weight range about 600 grams to 800 grams and age range about 1 to 2 years. The sample were observed macroscopically including the location, shape, color, consistency, weight, length and width. Furthermore, the sample were fixed with 10% formalin solution and continued with the process of making preparations and staining with hematoxylin-eosin (HE). The results showed that the testes of the green junglefowl were located in the abdominal cavity which was seen by the mesorchium. The testes are adjacent to several organs such as kidney, liver, spleen and proventriculus. The testes are asymmetrical, that is the left testicle is longer than the right testicle, while the width of the testicle is between 1.1 mm to 3.4 mm. The testicular weight is <1 gram. The testes are light yellow in color, have a smooth surface and are soft in consistency. Histologically, the testes of jungle fowl are composed of seminiferous tubules and interstitial tissue, and surrounded by a testicular capsule consisting of layers of tunica serous, tunica albuginea and tunica vasculosa. Sertoli cells and spermatogenic cells consisting of spermatogonia, primary spermatocytes, secondary spermatocytes and spermatids are scattered in the seminiferous tubules. The interstitial testes contain several components such as connective tissue, Leydig cells and blood vessels.

Abstract

This study is aimed at recognizing the effect that the addition of juice from watermelon (Citrulus lanatus) as antioxidants against motility and semen viability of pigs. The source of cement used in research came from the landrace boar. The semen of the pig was collected using the method of massage with the help of dummy sow. Cement is macroscopic and microscopic. The natural dilution material used is lontar. The treatment of the juice of 100 µL/10 mL, 200 µL/10 mL, 300 µL/10 mL, 400 µL/10 mL, 500 µL/10 mL. Liquid semen evaluations are performed every two hours after storage and sperm motility and viability evaluations of spermatozoa. The addition of watermelon juice (Citrulus lanatus) P3 treatment group at a dose of 300 µL/10mL has the best possible result in sustaining the motility of spermatozoa.
