Abstract

The low quality of vannamei shrimp seeds during larval rearing causes vannamei shrimp seeds to be more susceptible to disease, thus affecting production success. This situation can be overcome by increasing the immune response of vanamei larvae through the administration of vitamin C. This study aims to evaluate the effectiveness of Artemia salina bio encapsulation with vitamin C to increase immunity against vibriosis disease of vannamei shrimp larvae. The treatment tried was the addition of vitamin C through A. salina bio encapsulation with four different doses, 20, 30, 40, and 50 ppm as well as control (without vitamin C), each with three replicates using a Completely Randomized Design (CRD). Vaname shrimp seeds were reared from Mysis-PL11 stadia in 50-liter capacity crates, 40-liter volume of media water with a density of 40 fish/liter, then checked Total hemocyte count (THC), Differential hemocyte count (DHC) before and after the challenge test was carried out by using Vibrio harveyii bacteria. The results showed that the effectiveness of the immunostimulant vitamin C through A. salina bio encapsulation to prevent vibriosis had a significant effect on the immune system of Mysis-PL11 stadia vannamei shrimp larvae with the highest THC value of 41 x 104 cells/mm, DHC (66.67% hyaline, 27 .67% semi-granular, 67.67% granular) in the treatment with the addition of 50 ppm vitamin C.

Abstract

Kefir is a fermented milk product made by inoculating milk with kefir grains, a combination of bacteria and yeast. These microorganisms will play a role in the fermentation of lactic acid and alcohol, which can provide a therapeutic effect. The presence of probiotics in feed can increase enzymatic and digestive activity. As a natural probiotic, Kefir contains various strains of bacteria and yeast that can be used as a substitute for antibiotics that are limited in their use nowadays. The effectiveness of kefir as a probiotic was studied on the production, feed efficiency, and relative weight of the digestive tract in broiler chickens. This study used DOC broiler strain MB 202 with as many as 200 unsexing using a completely random design with four treatments and five replicates for five weeks. Treatment consisted of T0 = basal ration (control), T1 = basal ration + 1.5% probiotic kefir, T2 = basal ration + 3% probiotic kefir, T3 = basal ration+ 4.5% probiotic kefir. The kefir used comes from goat's milk which was given as much as 10% grain kefir fermented for 48 hours. The ANOVA resulted from a real difference (P<0.05) in performance for each treatment compared to the control. At the same time, the intestinal weight parameters of the digestive tract did not show a real difference (P>0.05). The addition of 4.5% probiotic kefir showed the best results on four performance parameters, including consumption, weight gain, and feed conversion ratio, which is also supported by the highest carcass yield compared to other treatments.
