Pancytopenia in Dogs – Mechanics to Differentiate Sepsis with Non-sepsis
Pancytopenia manifests as a reduction in circulating myeloid, erythroid, and megakaryocytic cell lines, with causes ranging from infectious, neoplastic, and immune-mediated diseases to sepsis and various drugs. This study endeavors to pinpoint the etiological agents of pancytopenia and establish parameters for distinguishing sepsis from non-sepsis cases. Clinical signs indicative of bleeding tendency and sepsis were identified, and animals exhibiting pancytopenia upon hematological analysis underwent further evaluation, including hemato-biochemical analysis, bone marrow cytology, PCR analysis, and flow cytometry, to ascertain the underlying causes. Discriminant function analysis was performed on 12 parameters obtained from 37 pancytopenic dogs and 20 healthy dogs, with the objective of distinguishing between sepsis and non-sepsis cases. Mean fluorescence intensity levels against platelets were recorded at 24.6% and against RBCs at 26.1%, confirming the presence of immune-mediated thrombocytopenia and anemia. Over a span of 2 years, the incidence of pancytopenia was higher in young animals. In our study, the identified etiologies among pancytopenic dogs were predominantly hemoprotozoan infections, accounting for 62% (41 dogs), followed by immune-mediated diseases at 24% (16 dogs). Significantly, five parameters - erythrocyte count, leukocyte count, platelet count, temperature, and heart rate were identified as significantly discriminatory between dogs with sepsis and those without sepsis. The higher incidence of pancytopenia in young animals can be attributed to infectious and secondary immune-mediated diseases. Among the different hemato-biochemical, physical parameters leukocyte count followed by RBC count was found to be the suitable parameters to differentiate sepsis and cases without sepsis in pancytopenic cases. This was also confirmed by the area under the curve of more than 80% and 78%, respectively, in the receiver operating curve, and 100% of originally grouped cases were correctly classified at a 99% confidence interval.
Optimizing Weed Control in Onion Cultivation for higher yield and returns: Techniques and Effectiveness
Weeds pose a major problem for the raising of crops and compete with the crop for around 26 essential resources, among them moisture, nutrients, space, and light are significant. They cause a substantial percent of decrease in both the yield and quality of the produce. In addition, weeds serve as alternative hosts for different insects and pathogens, which are the basis of causing pests and diseases respectively. Onions are densely planted because they have a shallow root system. It requires more labour with skill and patience to remove the weeds without disturbing the root system. Negligence is directly proportional to crop economics. Currently, the availability of labour is meagre. In such situations, following of more than one method of weed control like chemical, cultural, biological, or other methods which are directly enhances the yield and quality of the produce by following cost-effective methods are need of the present conditions. To achieve this using integrated weed management strategies can enhance crop yields through the suppression of weeds. This paper aims to identify the appropriate herbicides and their application rates for effective weed management, under different methods of planting and soil conditions and explains the other suitable and cost-effective weed management methods.
Unlocking Mustard Yield with Sulphur, Hydrogel and Bio-boosters for higher Profits from Soil to Oil
A field experiment carried out in rabi 2020 at Agronomic Farm, SGT University Gurugram. It estimates the sulphur impact, fungicides, and harmful azotobacter on the mustard production and its impact on yield and yield components. A mustard variety Recommended for Commercial Cultivation (RH-725) is used in the experiment. The experiment was laid out in randomized block design with 9 treatments replicated thrice:T1 {Control (No fertilizer)}, T2 {100% RDF}, T3 {100% RDF+ 40 kg/ha S @ first and third irrigation + Azotobacter seed treatment (84 ml/litre/ 20 kg seed)}, T4{100% 100% RDF + Hydrogel 5 kg/ha+40 kg/ha S @ second and third irrigation + Humic acid (5 ml/l) first, second and third irrigation}, T5 {75% RDF + Humic acid (5 ml/l) @ first, second and third irrigation + 40 kg/ha S @ second and third irrigation}, T6 {75% RDF + Sea weed extract (granule) 25 kg/ha @ first and second irrigation + Sea weed extract spray 5ml/l @ first, second and third irrigation}, T7 {75% RDF + Humic fulvic potassium acid 5 ml/ l @ first, second and third irrigation}, T8 {75% RDF+ Hydrogel @ sowing time 5 kg/ha}, T9 { 75% RDF + 40 kg/ha S @ first and third irrigation + Azotobacter seed treatment The highest plant height (185 centimeters), dry matter accumulation (34.90 grams per plant), siliquae per plant (113.33), test weight (4.66 grams), seed yield (2240 kg/ha), stover yield (7518.33 kg/ha) were observed in T3 which is (100% RDF+ 40 kg/ha S @ first and third irrigation + Azotobacter seed treatment (84ml/litre/20 kg seed)). According to the analysis of economics, T3 yielded higher net return (89, 236 Rs. ha-1) which was the most profitable treatment. According to the study, the use of 100% RDF and application of 40 kg/ha S at first and third irrigation and Azotobacter seed treatment (84 ml/litre/20 kg seed) T3 improved growth parameters, yield and yield attributes and economic return of mustard.
Enhancing quality parameters of sesame and potato through organic and inorganic nutrient management practices in sesame -potato cropping sequence
The current study was conducted at the ICAR - CPRI-RS, Gwalior (M.P.) during the kharif and rabi seasons 2020-21 and 2021-22 on the quality parameters of sesame and potato crops in sesame – potato sequence as influenced by organic nutrient management. The experiment was designed having seven treatments in the Randomized Block Design (RBD) with four replications. The organic treatment comprised of crop residue @ 25 t ha-1 with bio-fertilizer (Azotobacter and PSB), FYM @25 t ha-1, vermicompost @7.5 t ha-1, neem cake @ 5 t ha-1 in different treatments including control, 100% RDF and INM (RDF+FYM). The result revealed that among all the organic manures, RDF and integrated treatments, oil content was non-significant but effect on protein content, protein and oil yields were found significant during both the years. Treatment T7 (100% RDF + FYM @ 25 tha-1) showed best results in quality parameters i.e., oil yield (454 and 427 kg ha-1), protein content (19.1 and 18.8%) and protein yield(180 and 163 kg ha-1)as compare to other treatments in sesame crop during 2020-21 and 2021-22. Application of 100% RDF NPK (inorganic practices) gave higher oil content (48.5 and 49.4%) during 2020-21 and 2021-22. Application of 100% RDF + FYM @ 25 t ha-1recorded higher starch content (14.17 and 14.01%), starch yield (1199.4 and 1257.4 kg ha-1) and protein yield (670.1 and 726.6 kg ha-1) but crop residue @ 25 t ha-1 + bio-fertilizer (Azotobacter + PSB, @ 1 l ha-1each respectively) procured the highest protein content (8.32 and 8.26%) in potato during both the years and other quality parameters i.e., tuber dry matter content, water % and true density % which were observed non-significant during both the years in potato crop.
Assessment of Major Sources of Greenhouse Gas Emissions in Livestock Farming Systems Using Life Cycle Assessment Methodology
The present study employs the Life Cycle Assessment (LCA) methodology to evaluate the environmental impacts associated with greenhouse gas (GHG) emissions and emission intensity (Ei) from milk production, considering a system boundary extending from “cradle to farm gate.” The research was undertaken to estimate the percentage contribution of various farm activities namely enteric fermentation, fertilizer application, electricity and diesel use, and dung management to the total global warming potential (GWP) across crossbred cattle farms in eight districts of Haryana. The farms were categorized into three production levels: low, medium, and high. Results identified enteric fermentation as the principal hotspot of GHG emissions, followed by emissions arising from fertilizer use and electricity consumption. No significant differences were observed in enteric emissions among the three production groups. However, statistically significant variations were found in the emission percentages attributable to fertilizer, electricity, diesel, and dung management. The findings underscore the need for targeted mitigation strategies to enhance the environmental sustainability of milk production systems in the region.
