Permasalahan utama dalam budidaya udang vaname adalah serangan penyakit yang menyebabkan pertumbuhan udang menjadi kurang optimal. Penelitian ini bertujuan untuk menganalisis pengaruh ekstrak daun petai cina (L. leucocephala) terhadap performa udang vaname (L. vannamei). Penelitian ini dilakukan selama 60 hari menggunakan udang vaname berukuran PL-20. Metode yang digunakan pada penelitian ini adalah metode eksperimental dengan Rancangan Acak Lengkap (RAL) yang terdiri atas 4 perlakuan dan 3 ulangan yaitu, P1: tanpa penambahan ekstrak daun petai cina (kontrol), P2: ekstrak daun petai cina 1% v/w , P3: ekstrak daun petai cina 2% v/w dan P4: ekstrak daun petai cina 3% v/w.. Hasil penelitian ini menunjukkan bahwa penambahan ekstrak daun petai cina dengan dosis yang berbeda pada pakan udang vaname memberikan pengaruh yang nyata terhadap pertumbuhan dan nilai FCR udang vaname, tetapi tidak mempengaruhi tingkat kelangsungan hidup (SR) udang vaname. Diduga bahwa ekstrak daun petai cina mengandung senyawa glycerin, erythritol dan inositol. Penambahan ekstrak daun petai cina sampai dengan dosis 2% v/w dapat memberikan peningkatan bobot mutlak 3,70 g, panjang mutlak 6,13 cm, laju pertumbuhan spesifik (SGR) 5,7 g/hari dan rasio konversi pakan (FCR) 0,9. Oleh karena itu ekstrak daun petai cina mempunyai potensi untuk dimanfaatkan sebagai feed additive non nutritif pada budidaya udang vaname..

In the present study, Bacillus velezensis (BV007, CGMCC No. 20039) was isolated from the gut of Litopenaeus vannamei, and the effects of BV007 on the growth performance, immune responses, and intestine microbiota of the shrimp were investigated. A total of 1,200 healthy shrimp (3.0 ± 0.3 cm, 0.32 ± 0.8 g) were randomly divided into four groups, and fed diets supplemented with different levels of BV007 (C: 0; BV1: 1 × 105 CFU/g; BV2: 1 × 107 CFU/g; and BV3: 1 × 109 CFU/g) for 8 weeks. The results showed a significantly increased final body length (FBL), length gain rate (LGR), final body weight (FBW), weight gain rate (WGR), plumpness index (PI), and specific growth rate (SGR) in shrimp fed with BV007 for 42 days compared with shrimp fed with control diet. The activity of α-amylase in hepatopancreas was also significantly increased in the BV007-administered groups. After 42 days of growth trial, the challenge test with Vibrio parahaemolyticus was conducted for 2 weeks. The enhanced immune responses were exhibited by shrimp fed with BV007 after V. parahaemolyticus challenge, particularly in respiratory bursts and superoxide dismutase, catalase, and alkaline phosphatase activities. Moreover, the administration of BV007 could considerably increase the abundance of potential probiotics (Bacillus) and reduced the abundances of potential pathogenic bacteria (Vibrio) in shrimp intestines. In conclusion, the dietary supplementation with B. velezensis BV007 could promote the growth performance, enhance the immune responses, and modulate the intestine microbiota of shrimp, and 107 CFU/g feed was recommended to be used as a feed additive to enhance the growth and health status of shrimp.

Abstract The objective of this study was to investigate the effects of Caulerpa racemosa (Agardh, 1873) polysaccharides (CRP) on non-specific immunity of the white shrimp, Litopenaeus vannamei (Boone, 1931). The extracted polysaccharide consists of galactose, glucose, and mannose. Total polyphenolic compound and total flavonoids content in CRP were determined. In vitro CRP treatment did not alter cell viability of haemocytes and significantly activated phenoloxidase (PO) activity, superoxide anion production capacity, phagocytic rate, and index in haemocytes. Immune parameters, such as total haemocyte count, PO activity, phagocytosis, and superoxide anion production, were significantly elevated in CRP-fed shrimp during the rearing period. Malondialdehyde levels in the hepatopancreas of CRP-fed shrimp were lower than in control shrimp from day 7 to day 28. These results show that CRP exhibits antioxidant activity and can activate immune responses of white shrimp in vitro and in vivo. Therefore, CRP can be considered a functional feed additive to improve white shrimp immunity.

An experimental study was carried out during seven weeks to preliminarily evaluate the effect of the dietary inclusion of powder from the tuber Lasianthaea podocephala, commonly known as the San Pedro daisy or pionilla, as a feed additive on the production parameters, food consumption, and nutritional condition of the white shrimp, Litopenaeus vannamei, intensively farmed under laboratory conditions. Hypothetically, the additive should improve these parameters as it does when used for humans. The powder was included at different levels (0 [Control], 0.2 [T1] and 1 g kg-1 [T2]) in a commercial shrimp feed. The tuber powder exhibited a free amino acid profile being arginine (8.59 mg g-1) and glutamine (3.36 mg g-1) the most abundant. Feed consumption was not influenced by any treatment; however, the survival and the overall production responses were higher in both treatments using the powder (T1 and T2) compared to the control. No significant differences were detected in muscle concentrations of lactate and glucose, although higher protein and lower cholesterol concentrations were observed in shrimp reared in the control. The lower cholesterol concentration of shrimp from the control could be associated to a poor nutritional status. In conclusion, addition of the powder of San Pedro daisy did not improve the feed consumption, but apparently had a positive effect on survival, production response and nutritional status of shrimp. These responses could be associated to an hypothetic effect of some plant components at a nutritional-molecular level, or to a possible antimicrobial effect; however, further specific studies are needed.
