This study was conducted to investigate the influence of dietary distillers dried grain (DDG) level on growth and body composition of juvenile olive flounder (Paralichthys olivaceus). Five diets (designated as DDG0, DDG7, DDG14, DDG21 and DDG28) were prepared to contain 0, 70, 140, 210 and 280 g kg^?1 DDG. Three replicate groups of fish averaging 11.6 ± 0.1 g were fed one of the diets for 8 weeks. Weight gain of fish fed diets containing 70–280 g kg^?1 DDG was not different to that of fish fed DDG0 diet (P > 0.05). Feed efficiency of fish fed DDG21 and DDG28 diets was lower than that of fish fed DDG0 diet (P < 0.05). The antioxidant enzyme and digestive enzyme activities were not affected by dietary DDG levels. The results of this experiment suggested that DDG is a valuable ingredient as a candidate to replace wheat flour in the diet and could be used up to 280 g kg^?1 for the growth of olive flounder. On the other hand, if lower feed efficiency of fish fed 210–280 g kg^?1 DDG is considered, up to 140 g kg^?1 DDG in diet is recommended for optimum feed utilization of fish.  相似文献

Evaluation of chitosan and alginate immobilized Methylobacterium oryzae CBMB20 on tomato plant growth     

Mak Chanratana  Gwang Hyun Han  Manoharan Melvin Joe  Aritra Roy Choudhury  Seshadri Sundaram  Md. Abdul Halim 《Archives of Agronomy and Soil Science》2018,64(11):1489-1502

Methylobacterium oryzae CBMB20, a promising plant growth promoting bacteria (PGPB) and a biocontrol agent, was immobilized in different formulations such as wet chitosan, dry chitosan, wet alginate and dry alginate and were tested for tomato plant growth promotion. Chitosan solution (1.5%) with pH 5.5–6.0 and 90 min contact time was found optimal for immobilization. The chitosan formulations showed better entrapment efficiency and good degradability resistance apart from slow release of cells under prolonged incubation. Survivability of bacteria (80%) was observed in wet chitosan formulation even after 90 days of storage at 4°C. The spermosphere survival of bacteria was high in both dry and wet chitosan formulations applied soils even after 21 days under greenhouse conditions. While the alginate formulation degraded fully, partial degradation of chitosan formulation was observed even after 30 days, indicating its ability to support the survival of M. oryzae CBMB20 in soil. Plants inoculated with wet chitosan formulation registered 1.3 fold increase in the shoot and root length and dry weight compared to other treatments. Hence, chitosan formulation supporting better plant growth compared to alginate will be a better carrier for taking bacteria to the plant rhizosphere and thereby promote plant growth.  相似文献

Effect of laboratory‐isolated Lactobacillus plantarum LGFCP4 from gastrointestinal tract of guinea fowl on growth performance,carcass traits,intestinal histomorphometry and gastrointestinal microflora population in broiler chicken          下载免费PDF全文

P. G. Vineetha  S. Tomar  V. K. Saxena  M. Kapgate  A. Suvarna  K. Adil 《Journal of animal physiology and animal nutrition》2017,101(5):e362-e370

The study aimed to investigate the effect of feed supplements, viz Lactobacillus plantarum LGFCP4 (laboratory isolate from GIT of Guinea fowl), Lactobacillus acidophilus (NCDC, Karnal) and in‐feed antibiotic bacitracin methylene disalicylate (BMD) on growth performance, FCR, carcass traits and immune organs weight, intestinal histomorphometry and gastrointestinal microflora population in broiler chickens. In a completely randomized design, CARIBRO‐Dhanraja broiler chicks (n = 160) were used with four treatment groups. During the entire experimental duration of 35 days, treatment groups were provided with different dietary treatments (T1 – basal diet (negative control), T2 – antibiotic growth promoter BMD 20 g/100 kg feed (positive control), T3 – 1 × 10⁸ cfu of L. acidophilus/gm‐fermented feed +MOS 1 g/kg feed and T4 – 1 × 10⁸ cfu of laboratory‐isolated L. plantarum LGFCP4/gm‐fermented feed+ MOS 1 g/kg feed. After 35 days of experimental period, no significant results have been observed in different growth performance traits among treatment groups. Cut‐up parts and edible organs' weight remained unaffected by dietary supplementation, whereas weight of immune organs were significantly higher (p < 0.05) in L. plantarum LGFCP4‐supplemented group. At the end of feeding trial, significantly (p < 0.05) lower E. coli count was observed in crop of T4 birds, while in ileum, T2 and T3 showed lower count. In caeca, T2 group showed lowest E. coli count. Salmonella count in crop and ileum was significantly (p < 0.05) low in T3 and T4, while in caeca, T2 group showed lowest count. In terms of histomorphometry, duodenal villous height (VH), crypt depth (CD) and VH:CD ratio were higher for T3 and T4 and lowest values were obtained for T2 group. The results of the study showed that L. plantarum LGFCP4 isolated from GIT of guinea fowl can effectively replace in‐feed antibiotic growth promoters in broiler diets by altering intestinal villi morphology and improving the gut health by reducing the pathogenic microbial load.  相似文献   

Species Composition,Diversity and Productivity of Homesteads in Southeastern Bangladesh     

Md. Abiar Rahman  Masakazu Tani  Kazuo Asahiro  S. M. Asik Ullah 《Small-Scale Forestry》2017,16(3):295-309

A homestead is an integrated production system where trees, crops, livestock and poultry are found in and around the household residence in Bangladesh. It is a potential production unit that provides various product, service and ecological functions. Almost all people in Bangladesh including landless households have homesteads in which they grow trees and crops even in a small piece of land. This study characterizes the species composition, diversity and productivity of the homestead production system in the Teknaf peninsula, southeastern Bangladesh. Survey data collection was from a total of 180 homesteads covering five household categories: large, medium, small, marginal and landless. Vegetable, fruit, timber, and livestock and poultry were common components in the homestead production system. Various types of plants were mainly concentrated in back yards, front yards, boundaries and corners of homesteads. The mean number of tree species per homestead was about 15. In total, 189 tree and shrub species were recorded, and were distinctly high and low in the large (363.7) and landless (55.7) household categories. Species composition, diversity and productivity of homesteads were found to be related to household categories. Richness and diversity of tree and shrub species increased with household size. Betel nut was the dominant tree species followed by mango, jackfruit and coconut. Annual income from homesteads also varied among the household categories, with a mean contribution of the homestead to annual income of about 25 %. A large portion of homestead income came from betel nut trees. There is scope to increase species diversity and income by designing homesteads with the engagement of women and other family members.  相似文献   

Variation of mineral nutrient contents of modern and heirloom cultivars of cabbage in different regimes of soil fertility     

Allen V. Barker  Touria E. Eaton  Md J. Meagy  Emad Jahanzad  Gretchen M. Bryson 《Journal of plant nutrition》2017,40(17):2432-2439

An improvement in the mineral nutrient contents of fruits and vegetables is needed to offset reported declines in concentrations of these elements in fruits and vegetables. The declines have been associated with the high productivity of modern cultivars and to depleted soil fertility. This research addressed differences in mineral nutrient concentrations between modern F1 hybrids and heirloom cultivars of cabbage (Brassica oleraceae var. capitata L.)and among fertilization practices with conventional chemical or organic fertilizers and compost. Crop production was greater with the chemical or organic fertilizers than with the compost. Mineral nutrient composition did not vary between modern or heirloom cultivars or among fertilization regimes but varied among cultivars, suggesting that cultivar selection could lead to production of nutrient-rich cabbage. Neither mass of heads nor days to maturation of crops affected nutrient composition.  相似文献   

Allelopathic potential and an allelopathic substance in mango leaves     

Masahiko Suzuki  Md Sirajul Islam Khan  Arihiro Iwasaki  Kiyotake Suenaga  Hisashi Kato-Noguchi 《Acta Agriculturae Scandinavica, Section B - Plant Soil Science》2017,67(1):37-42

The present study was aimed to determine the allelopathic potential of mango (Mangifera indica L.) leaves and to identify allelopathic substances in the leaves. The aqueous methanol extracts of mango leaves inhibited seedling growth of garden cress, radish, rapeseed, foxtail fescue and crabgrass, and the inhibitory effects increased with the increasing extract concentration, suggesting that mango leaves may contain allelopathic substances. The extract was then purified by several chromatographic runs through a bioassay-directed fractionation, and an growth inhibitory substance was isolated and identified by spectral data as methyl-3,4,5-trihydroxybenzoate (methyl gallate). Methyl gallate at the concentration of 10 mM inhibited 98.6% and 99.8% of root and shoot growth of garden cress relative to the control, respectively, and 94.4% and 49.3% of those of foxtail fescue, respectively. The concentrations of methyl gallate required for 50% growth inhibition (I₅₀) on garden cress roots and shoots were 3.9 and 3.3 mM, and those on foxtail fescue roots and shoots were 1.5 and 9.5 mM, respectively. It is the first report of an allelopathic substance in mango leaves and allelopathic activity of methyl gallate. Therefore, the mango leaves may have potential as a soil additive material for the weed management options.  相似文献   

Anaesthetic efficacy of MS‐222 and AQUI‐S® in advanced size fry of rohu,Labeo rohita, (Hamilton‐Buchanan)          下载免费PDF全文

Md. Akbal Husen  Subodh Sharma 《Aquaculture Research》2016,47(8):2496-2505

Anaesthetic agents are very useful for reducing the stress caused by handling, sorting, transportation, artificial reproduction, tagging, administration of vaccines and surgical procedures in fish. The efficacy of two anaesthetics: MS‐222 and AQUI‐S^® were tested on rohu, Labeo rohita advanced size fry. The lowest effective doses that produced induction in 3 min or less and recovery times 5 min or less and meet the most criteria of good anaesthetic characteristics were 125 mg L^?1 of MS‐222, and 30 mg L^?1 of AQUI‐S^® in rohu, Labeo rohita advanced size fry. Induction times were significantly decreased with increased in the concentrations of any of the two tested anaesthetic agents. The lowest doses suitable for transportation of rohu advanced size fry observed were: 10–15 mg L^?1 of MS‐222 and 2.5 mg L^?1 AQUI‐S^®. Both anaesthetics showed promising to be used as anaesthetics for handling and transportation in rohu (Labeo rohita) advanced fry.  相似文献
