Influence of Dietary Zinc Supplementation on Serum Minerals (Zinc, Calcium, Phosphorus) and Liver Enzyme Level (ALP, ALT, GGT) in Layer Chicken
No full textThe Indian industry is presently focussed in production of eggs that have higher or enriched levels of certain nutrients. These eggs are capable of safeguarding the health of consumers. Designer eggs have high market demand because of the consumers’ willingness to purchase designer eggs due to its’ nutritional qualities additional to regular eggs. Considering these facts the current study was planned to produce zinc enriched eggs by supplementing laying hens’ diet with required levels of zinc. The present study was conducted at the Department of Veterinary Physiology, College of Veterinary and Animal Sciences, Mannuthy, for 12 weeks. A total of 28 week old thirty two laying hens, belonging to crossbred (White Leghorn N strain and Desi) housed in the animal house attached to the department were used in the experiment. The treatments of this study included a control diet (according to BIS, 2007) fed group and zinc-supplemented group. Each of the experimental treatments had four replicates with four birds with all standard managemental conditions. The functional liver status of birds was not altered due to zinc supplementation, since the present study neither caused any toxicity nor imparted any negative effect on the production performance. Highly significant effect was observed on serum concentration of zinc and calcium. However, the phosphorus levels of treated birds were not significantly different from the control group
Assessment of Okra Genotypes for Resistance against Shoot and Fruit Borer, Yellow Vein Mosaic Virus and Enation Leaf Curl Virus under Natural Field Conditions
No full textIndia is a key player in okra production with Andhra Pradesh leading state in cultivation. However, the crop faces significant challenges from Yellow Vein Mosaic Virus (YVMV) and enation leaf curl virus (ELCV) which severely impact yield and quality. The study conducted at the Vegetable Research Farm, Regional Horticultural Research Station, evaluated 37 okra genotypes for resistance against these biotic stresses. The genotypes, including 8 parents and 28 hybrids were assessed under three different environments in a Randomized Block Design. The results revealed that none of the genotypes were immune to shoot and fruit borer infestation, YVMV and ELCV. However, some hybrids demonstrated resistance or tolerance to these stresses with the top three hybrids displaying high levels of resistance against shoot and fruit borer infestation, moderate resistance against YVMV and high tolerance to ELCV. Nevertheless, none of the hybrids showed consistent immunity across all environments
Impact of Covid-19 on Farmers\u27 Behavior in Chikkaballapur District, Karnataka, India
No full textThis study explored how COVID-19 affected farmers in Chikkaballapur District, Karnataka, India. Using an ex-post-facto research design, data were collected from 50 randomly selected farmers through a pretested structured interview schedule. The goal was to understand their perceptions of the pandemic\u27s impact on farming, productivity, economy, markets, labour, and community well-being. Statistical methods like mean, standard deviation, coefficient of variation, correlation, and multiple regression analysis were used to analyse the relationships between various factors. The findings showed significant variability in farm size and income, indicating a wide range of differences among farmers. Notably, changes in economic factors were significantly related to farm size, while changes in production were significantly related to education. Health and sanitation were negatively correlated with changes in farm technology, suggesting that better infrastructure could influence the adoption of new technologies. Age and education significantly impacted changes in farm management, highlighting the importance of demographic factors in farming decisions. The study emphasized the complex effects of the pandemic on farming practices and highlighted the need for targeted interventions. Recommendations include financial support programs, improved market access, promotion of digital tools, and diversified cropping strategies to help farmers build resilience and sustainability. These measures aim to reduce the adverse effects of crises and improve the overall well-being of farming communities

During the third week of August, the 34th SMW recorded the first peak of 12.97 per cent leaf damage. After a slight decrease in leaf damage, a second peak was seen in the 38th SMW, in third week of September, with 14.89 per cent leaf damage. In the following weeks, there was a decrease in the leaf damage, reaching its lowest during the 44th SMW, which fell on the fifth week of October, with 0.78 per cent leaf damage. The correlation studies showed a significant positive correlation between larval population and minimum temperature, morning relative humidity, and morning and evening vapor pressure (r = 0.613*, 0.515*, 0.637* and 0.577*, respectively)
Strengthening Method of Waste Concrete Aggregate
No full textAfter the construction solid waste is broken, it is directly used as recycled aggregate, which often has the disadvantages of large porosity, high water absorption and low strength, resulting in low strength and poor durability of the recycled concrete prepared by it. Therefore, the effective use of recycled aggregate in concrete is limited. For this reason, researchers have carried out systematic research on the modification of recycled aggregate in order to realize the reuse of resources. The research shows that the strengthening methods of recycled aggregate can be divided into physical methods, chemical methods and microbial methods to make up for the defects of recycled aggregate. In this paper, the concrete content of recycled aggregate strengthening method is reviewed, which provides some theoretical support for the treatment of construction waste and its utilization as recycled aggregate
