SEDATION OF NILE TILAPIA WITH ESSENTIAL OILS: TEA TREE, CLOVE, EUCALYPTUS, AND MINT OILS

ABSTRACT Essential oils have been extensively used in many commercial applications, one of them being anesthetics. The effect of four essential oils (tea tree, clove, eucalyptus, and mint oils) on the sedation, recovery, and behavioral stress of Nile tilapia (Oreochromis niloticus) was evaluated. The sedative solutions, prepared with essential oils and anhydrous ethanol (1:4), were used for fish management procedures at a dose of 7.4 mL L-1 in a completely randomized block design with four treatments and seven replicates. The means were compared using Scott-Knott test (P < 0.05). Clove oil was found to be the most suitable oil for the immobilization of Nile tilapia; however, behavioral observations indicate that tea tree oil was the most efficient in reducing stress.

The present work aimed at determining the effects of the association between the periphyton-based system with the bioflocs-based system in the intensive culture of juvenile Nile tilapia (1.56 ± 0.07 g; 72 fish m-3), on variables of water quality, growth performance and effluent quality after 10 weeks. The experiment was arranged in a 2 x 2 factorial randomized block design with four treatments and five repetitions each. The factors tested were the following: ‘underwater structure’ (absence and presence) and ‘adjustment of the C: N ratio of water’ (no and yes). The final fish body weight, specific growth rate and yield were higher (p < 0.05) in the C: N-adjusted tanks. The presence of submerged structures in the tanks had no significant influence on those same variables. It was concluded that the periphyton-based system is not indicated for intensive farming of Nile tilapia, in which there is a high allowance of artificial feed to fish.

Penyakit layu yang disebabkan oleh cendawan Fusarium oxysporum f. sp. cubense (Foc) merupakan salah satu penyakit penting pada tanaman pisang. Teknik pengendalian yang efektif dan berwawasan lingkungan perlu terus diupayakan, di antaranya melalui penggunaan pestisida nabati. Penelitian ini bertujuan mengetahui pengaruh pemberian daun beberapa tumbuhan penghasil minyak atsiri terhadap jumlah propagul awal Foc dalam tanah dan pengendalian penyakit layu Fusarium pisang pada skala rumah kasa. Penelitian dilakukan di Laboratorium Penyakit dan Rumah Kasa Balai Penelitian Tanaman Buah Tropika Solok mulai bulan Februari sampai dengan Juni 2009. Rancangan yang digunakan dalam percobaan ialah acak kelompok dengan lima perlakuan dan empat ulangan, masing-masing ulangan terdiri atas lima tanaman. Perlakuan tersebut adalah empat jenis daun tumbuhan penghasil minyak atsiri yaitu : (A) daun nilam, (B) serai, (C) daun kayu manis, (D) daun cengkeh, dan (E) tanpa perlakuan (kontrol). Tanaman uji adalah bibit pisang Ambon Hijau hasil perbanyakan kultur jaringan umur 2 bulan setelah aklimatisasi. Hasil penelitian menunjukkan bahwa pemberian daun tumbuhan penghasil minyak atsiri mampu menekan jumlah propagul awal Foc di dalam media tanam. Persentase penurunan propagul Foc awal dalam media yang berumur 5 minggu setelah pemberian tumbuhan penghasil minyak atsiri berkisar antara 50,1-70,6%. Semua perlakuan, kecuali daun nilam, juga mampu memperlambat munculnya gejala atau masa inkubasi penyakit. Masa inkubasi penyakit paling lama terjadi pada perlakuan pemberian daun cengkeh, diikuti dengan perlakuan pemberian daun kayu manis dan daun serai dengan perpanjangan masa inkubasi masing-masing sampai 22 dan 15 hari dibandingkan dengan kontrol. Pemberian daun tumbuhan mengandung minyak atsiri belum berakibat pada penurunan persentase dan intensitas serangan penyakit, sehingga perlakuan pemberian tumbuhan penghasil minyak atsiri perlu dikombinasikan dengan metode pengendalian lain agar lebih efektif dalam menekan penyakit layu Fusarium.<br /><br /><br /><br />Fusarium wilt caused by Fusarium oxysporum f. sp. cubense (Foc) is the most important disease on banana. Effective and environmental friendly techniques in controlling the disease need to be effort continually, among of them are with application of biopesticide to suppres Foc. The objectives of the research were to know the effect of some plant producing essential oils on initial number of propagule of Foc in soil and disease development of Fusarium wilt of banana. The research was conducted at Indonesian Tropical Fruits Research Institute Solok from February to June 2009. A randomized block design with five treatments and four replications was used, whereas each treatment consisted of five plants. Four types of plant producing essential oils as treatments, namely (A) crude of patchouly leaves, (B) crude of lemon grass, (C) crude of cassia leaves, (D) crude of clove leaves, and (E) water as control treatment were used. Ambon Hijau cultivar derived from tissue culture propagation of 2 months after acclimatization was used as experiemental material. The result showed that application of leaves of plant producing essential oils decreased initial number of Foc propagules in the banana cultivation media. Percentage of reducing the number of initial propagule of Foc in medium after infestation of plant producing essential oils ranged between 50.1-70.6%. All application of plant producing essential oils, except crude of patchouly leaves, was effective to reduce the incidence of wilting or incubation period of the disease. The longest disease incubation period was determined on treatment with clove leaves, followed by cassia and lemon grass leaf with extending incubation period up to 22 and 15 days respectively compared to control. Application of the plant producing essential oils was not successfully applied in suppressing the percentage of wilt and disease intensity on banana under screenhouse condition. Therefore combination treatments with other techniques in conjunction to improve the effectivity of the plants in controlling Fusarium wilt disease are suggested.

Abstract Eighty-eight feedlot finishing Nellore bulls (358 ± 38.5 kg BW) were used in a randomized block design (initial BW) with a 2×2 factorial arrangement to test the effects of two feed additives (MON - Sodium Monensin, 26 mg/kg DM vs. Crina®RumistarTM - combination of blend of essential oils - 90 mg/kg DM + exogenous α-amylase - 560 mg/ kg DM; DSM Produtos Nutricionais Brasil S.A.) and two roughage sources (CS - corn silage vs. SB - sugarcane bagasse) on fecal starch. Animals were adapted to the high grain diets, starting with 20% of physically effective NDF of each roughage source, and gradually decreased to 10% after 20-d. Final diets contained 19.5% CS or 12% SB, corn grain (70.7 and 78.2% for CS and SB diets, respectively), 5.5% soybean meal, 4% mineral and vitamin mixture and 0.3% urea, on DM basis. Feed intake was daily recorded individually during 104 days using individual pens or Calan-gate system. To determine fecal starch concentration, feces from each animal were sampled on days 0, 58 and 85-d of the feeding period. Data were analyzed using the Mixed procedure of SAS considering roughage source, feed additives and interaction as fixed and block as random effects. No interaction between feed additives and roughage sources was observed. Animals fed CS had 20% higher DMI (P < 0.0001) than those fed SB, but roughage sources not affected (P = 0.15) fecal starch concentration. Diets containing different additives did not affect DMI (P = 0.17); however, animals fed Crina®RumistarTM had 21% lower fecal starch concentration (15.9 vs. 21.1 %DM; P = 0.01) than animals fed MON, respectively. Therefore, supplementation with Crina®RumistarTM is an effective substitute of monensin in finishing cattle fed high concentration diets regardless of roughage source, improving the use of starch by the animals and reducing its excretion, reflecting on a lower environmental impact.

Abstract Our objective was to evaluate the effects of associating feed additives on feedlot performance of Nellore bulls. One hundred and sixtieth Nellore bulls (iBW, 380± 5.8 kg; age, 18 mo) were allocated in 20 pens (n = 8/pen), in a completely randomized block design, according to the treatments: 1) MON+VM - Sodium Monensin (MON, 25 mg/kg DM, Elanco Animal Health, Indianapolis, IN), + Virginiamycin (VM, 30 mg/kg DM, Phibro Animal Health Corporation, Guarulhos, São Paulo), and 2) CRD - Crina® RumistarTM + HyD® - a blend of essential oils, 90 mg/kg DM + exogenous α-amylase, 560 mg/kg DM + 25-hydroxy-vitamin-D3 at 1 mg/animal/d (DSM Nutritional Products, Basel, Switzerland). The initial BW was utilized as a criterion for block formation. Pens were considered experimental units (10 pens per treatment). Animals were adapted to the diets during 14 days with gradually increasing concentrate level from 70% to 86% of diet DM, and fed for 90 days. Weight assessments were performed at day 0 and 90 after 14h fasting. Data were analyzed using PROC MIXED of SAS and means were separated using the PDIFF statement, adopting P < 0.05. Feeding CRD increased the DMI (12.13 kg vs. 10.52 kg, P < 0.01), ADG (1.86 vs. 1.63 kg/d, P < 0.01) and final BW (542 vs. 521 kg, P < 0.01) compared to animals fed MON+VM. In addition, feeding CRD increased final HCW in 15 kg (311 vs. 296 kg; P < 0.01), carcass ADG in 0,16 kg/d (1.31 vs. 1.15 kg/d; P < 0.01) and dressing percentage in 0.48 percent points (57.34 vs. 56.86%; P < 0.01) compared to MON+VM. The G:F (0.155, P = 0.53) and biological efficiency (137.9 kg DM/15 kg carcass, P = 0.87) were similar among treatments. Therefore, the inclusion of Crina® RumistarTM +HyD® can be used as a tool to increase carcass gain of feedlot finishing cattle.

The objective of this study was to evaluate the productive performance, organosomatic indices and liver-intestinal histomorphometric parameters of Nile tilapia (Oreochromis niloticus) juveniles, fed diets containing probiotics (yeast - Saccharomyces cerevisiae) and reared at different densities of storage. In this experiment, 450 juveniles of tilapia (2.9 ± 0.23 g) were distributed in 18 experimental units arranged in RAS and arranged in a randomized block design in a 2x3 factorial scheme. These animals were fed two diets, the first without yeast and the second containing 0.1% yeast inclusion and distributed in three stocking densities of 15, 25 and 35 fish / m3 (500, 833 and 1166 fish / m3). There was an improvement in the oxygenation of the medium with the use of yeast, as well as in the lowest stocking densities evaluated (15 and 25 fish / m³). However, lower specific growth rates and higher viscerosomatic index were observed in animals supplemented with 0.1% yeast. For the average area of hepatocytes, there was an interaction between the evaluated factors (use of probiotic x storage density), where the best values were found in the lowest storage densities (15 and 25 fish / m³), regardless of use or not of the probiotic. It is recommended to use a stocking density of 15 to 25 fish / m³ and a supplementation of 0.1% with yeast as a probiotic, in order to improve liver health and oxygenation of the water used to grow Nile tilapia juveniles cultivated in RAS.

Performance Results

The objective of this study was to evaluate the performance of Nile tilapia and the lettuce, watercress, and arugula vegetables in a gravel-bed aquaponic system using the aerated fish tank-to-vegetable growing bed volume ratios of 1:1 and 1:2. Each experimental unit consisted of an aquaponic module composed of two containers: one to allocate the vegetables (500-L tank with gravel, measuring 2 m2) and another to stock fish at the ratios of 1:1 (500-L vegetable:500-L fish tank) and 1:2 (500-L vegetable tank:1000-Lfish tank). The experiment was laid out in a randomized-block design with two treatments (500-L fish tank × 1000-L fish tank) and three blocks (periods). The performance of the Nile tilapia and of the vegetables did not differ significantly in response to the increasing fish tank volume, with the fish and the vegetables exhibiting good performance results in both volume ratios. In conclusion, in aquaponics, the fish tank-to-vegetable tank volume ratios of 1:1 and 1:2 are equally effective for the production of Nile tilapia and the lettuce, watercress and arugula vegetables.

Li, Y. L., Li, C., Beauchemin, K. A. and Yang, W. Z. 2013. Effects of a commercial blend of essential oils and monensin in a high-grain diet containing wheat distillers’ grains on in vitro fermentation. Can. J. Anim. Sci. 93: 387–398. Our objective was to evaluate in vitro effects of a commercial blend of essential oils (BEO) versus monensin (MON) on fermentation of a high-grain diet containing wheat distillers’ dried grains with solubles (DDGS). Two experiments were conducted. The first experiment was designed as a short-term batch culture to determine the optimum dose of BEO (0, 45, 90 or 180 mg kg−1DM) on fermentation variables. The second experiment was a completely randomized block design with a 2×2 factorial arrangement of treatments using the rumen simulation technique. A high-grain dietary substrate containing wheat DDGS was supplemented with 0 or 28 mg MON kg−1DM combined with 0 and 90 mg BEO kg−1DM. Monensin did not affect the total volatile fatty acid (VFA) concentration or the molar proportions of individual VFA, but reduced CH4production (mL L−1gas; P=0.01) and disappearance of DM (P=0.04). Supplementation of BEO did not affect VFA concentration, but decreased (P=0.01) the molar proportion of acetate and reduced (P=0.02) the acetate to propionate concentration ratio and CH4production (mL g−1digested organic matter). The BEO increased (P=0.01) disappearance of neutral detergent fiber without affecting disappearance of other nutrients. These results indicate that supplementation of high-grain dietary substrate containing wheat DDGS with BEO improved fermentation pattern by increasing propionate concentration, reducing CH4production, and increasing fiber digestibility. This commercial BEO could be a potential substitute for MON for beef cattle fed high-grain diets containing DDGS.

Adequate Management

The management of micronutrients in oil palm trees in the Brazilian Amazon is still underdeveloped; thus, information on plant demands and their interactions with other nutrients is required to create adequate management procedures. The objective this work was to evaluate the effects of phosphate, potassium, and magnesium fertilization on micronutrient concentrations in leaves of oil palm trees. The experiment was carried out in the Brazilian Amazon in a randomized block design in a 4 x 2 x 3 x 2 factorial scheme, using four phosphorus levels, two phosphorus sources (natural phosphate and triple superphosphate), three potassium levels and two magnesium levels. Phosphate fertilization increased the concentrations of boron, chlorine, and iron in leaves, while copper and manganese concentrations in leaves decreased with increased doses of phosphorus. Among the phosphorus sources, triple superphosphate provided higher chlorine concentrations in leaves. Potassium fertilization increased only chlorine concentrations in leaves, while magnesium supply did not alter micronutrient concentrations in leaves. Thus, phosphorus and potassium fertilizers are essential to provide adequate micronutrient concentrations in leaves of oil palm trees.
