A total of 200-day-old Cobb 500 broiler chicks were divided randomly into 5 experimental groups. Whereas groups T1, T2, T3, and T4 were offered basal feed supplemented with 2% Neem Leaf Powder (NLP), 2% Moringa Leaf Powder (MLP), 2% Jute Leaf Powder (JLP), and antibiotics, respectively. In this research, the total feed consumption of birds was significantly (P < 0.05) lower in the T1 and T2 group than in the T3 and T4 group. Final live weight was significantly (P < 0.05) higher in 2% MLP treated group T2 followed by T1, T3, and T0 group. Significantly (P < 0.05) better feed conversion ratio (FCR) was found in the T2 group compared to T0, T3, and T4 groups. There found no significant (P > 0.05) effect of treatments on the survivability percentage of birds. All the treatment groups showed an insignificant (P > 0.05) effect on dressing percentage and organs (liver, heart, and gizzard) weight of broiler chicken. Weight of immune organs (spleen and bursa) and blood parameters (concentration of hemoglobin, glucose, and cholesterol) were not influenced (P > 0.05) by dietary addition. Birds fed the lower amount of feed, higher body weight, and improved FCR were found in the 2% MLP treated group. In overall aspects, the effectiveness of 2% MLP addition was better than 2% NLP and 2% JLP as an antibiotic alternative.\u0000\u0000\u0000\u0000","PeriodicalId":11865,"journal":{"name":"European Journal of Agriculture and Food Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140689330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also performed a microbiological evaluation of the umeboshi. Additionally, using a questionnaire, we surveyed consumer preferences for umeboshi pickled using different additives. Salt-pickled umeboshi had a high pH and low citric acid content, resulting in a mild flavor, whereas umeboshi pickled in brine had a high malic acid content. After soaking in various salts, the acidity of pickled plums increased. Moreover, umeboshi pickled in Ca-supplemented brine exhibited high L-and a-values.

A nozzle cap containing two electrodes (spacing at 9 mm apart) was used to superpose charges to spray droplets under applied voltages of 2–12 kV in an electric field (E) of 8.9 × 105 V/m. From a tee-jet flat fan (TP11004VS) nozzle tip fitted into the electrode cap and positioned at 60 cm high above targeted Brassica campestris leave surfaces, the spray droplets were directed onto the leaves at a liquid flow pressure of 4 bar and travelling speed of 2 m/s. The measurements were done using Keithsley picoammeter to quantify spray chargeability (CMR), droplet sizes by lesser particle size analyzer (LPSA) and deposition on leaf surfaces by high-speed camera. In effect, droplet sizes of EC, L-77 and EC + L-77 decreased with an increasing applied voltage. The CMR of L-77 was lower than EC and highest for EC + L-77 composite solution. Based on Image analysis of droplets density per leaf area, maximum exposure of adaxial leaf surfaces intercepted many charged spray droplets than abaxial surfaces. As regressed, the quantity of charged spray deposition from EC + L-77 formulation was highest at both adaxial (approx. 27.44 Qd/cm2) and abaxial (approx. 5.57 Qd/cm2) hydrophobic leaf surfaces than EC of 26.12: 3.19 Qd/cm2 and L-77 of 24.80: 2.53 Qd/cm2, respectively. Also, contact angle, Theta E, of charged spray droplets was smaller than Theta C on adaxial than abaxial leave surfaces, a phenomenon attributed to high chemo-electrical properties of formulations that aided the direct flight, coiling and deposition of droplets in order of EC > EC + L-77 > L-77. Generally, there was no observable droplet rebound; hence, surfactant-pesticide composite spraying is considered suitable for electrostatic application in plant protection technology. Therefore, for effective application, charged droplets from glyphosate EC in silwet L-77 solution should be recommended, as it provides optimum droplet sizes, chargeability, contact angle and deposition on hydrophobic leave surfaces.\u0000\u0000\u0000\u0000","PeriodicalId":11865,"journal":{"name":"European Journal of Agriculture and Food Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140453240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A century ago, in 1924, the Austrian New Age philosopher Dr. Rudolf Steiner called for an agriculture differentiated from the prevailing direction of agriculture and one reliant on natural biological processes rather than synthetic chemicals. The European Union (EU) has set the goal to be of 25% organic by 2030. Organic agriculture presently accounts for 9.6% of EU agriculture (cf. the world figure is 1.6%). For the past two decades, the tally of EU organic agriculture hectares has grown at 6.7% pa to reach 15,639,063 ha (cf. the world total of 76,403,777 ha). At this historic rate of growth (of 6.7% pa), organics will account for 17.5% by 2030 (c. 28.2 m ha), which is well short of the goal. To reach 25% by 2030, the growth rate needs to be ramped up to 10.7% pa growth (and reach a total of 40.6 m ha). About half (n = 15) of the 31 countries committed to the 25% goal, comprising the EU, EEA, and EFTA, have more than 10% organic agriculture. That offers a good foundation on which to build to the goal. The other half (n = 16) each have less than 10% organic agriculture; they offer opportunities for substantial uptake of organics. The EU has a ‘Farm to Fork’ strategy (F2F) with an ‘Action Plan’ comprising three ‘Axes’ and 54 ‘Actions’ to achieve the 25% organic goal by 2030; however, milestones and waypoints are lacking. The EU goal is bold, but not as bold as the 100% organic goals of Sikkim, which has achieved its 100% goal, and Bhutan, which has not and is stalled at 1% organic.\u0000\u0000\u0000\u0000","PeriodicalId":11865,"journal":{"name":"European Journal of Agriculture and Food Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140457796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nine iso-caloric and iso-nitrogenous diets were formulated mainly from wheat/sorghum/soybean meal. Three levels of CSM none (0%), low (5%, 10%, and 15%) or high (6%, 12%, and 18%) in the starter, grower, and finisher diets, respectively, were included. The diets were supplemented with three levels of a composite xylanase and beta-glucanase product at 0, 100 or 150 mg/kg diet. Each of the nine dietary treatments was randomly assigned to 6 replicates, with 10 birds per replicate. Feed intake (FI) and weight gain (WG) were recorded on day 10, 24 and 35, and feed conversion ratio (FCR) was obtained from the data, while enzyme activities and nutrient digestibility were measured on samples collected on day 10 and 24, and day 24 only, respectively. Feed intake up to day 35 decreased (P < 0.05) significantly with increasing enzyme supplementation. On the CSM-containing diets, enzyme supplementation at 100 or 150 mg/kg improved WG up to day 24, with the heaviest birds (1514 g/b) observed in the low CSM with 100 mg/kg enzyme group. Enzyme supplementation improved (P < 0.01) FCR all through the growth phases and also improved (P < 0.05) ileal crude protein and starch digestibility. High levels of CSM decreased the digestibility of starch, but this was improved (P < 0.05) by enzyme supplementation, showing an interaction between CSM and microbial enzyme on starch digestibility. The digestibility of arginine, glutamic acid and threonine improved with increased CSM inclusion, and that of methionine improved with increased enzyme supplementation. There was an interaction effect (P < 0.01) between CSM and enzyme on magnesium digestibility. Cottonseed meal inclusion improved the digestibility of copper and potassium and reduced the digestibility of phosphorus, while that of calcium and manganese was increased (P < 0.01) with enzyme supplementation.
