CARCASS QUALITY OF LANDRACE X DESI PIGS UNDER SPLIT WEANING AND DIFFERENT FEEDING REGEMIES
An experiment conducted to the asses the carcass quality of Landrace X Desi pigs under split weaning and different feeding regime was carried out at Indian Veterinary Research Institute, Izatnagar, Barielly, Utter Pradesh. Eighteen pregnant gilts (62.5% Landrace and 37.5% Desi) were randomly divided into two groups (C and T, respectively) having 9 gilts each. After birth of piglets in control group were allowed to suckle their dams until 56 days of age and kept as control and weaned thereafter. In other half (T), heavier piglets (> 1.2 kg body at birth) were weaned at 28 days and remaining comparatively lighter piglets were weaned at 42 days after birth. Weaned piglets again distributed 3 subgroups with 15 piglets in each group and these piglets were fed with 100% Concentrate ration, 50 Concentrate and 50% Kitchen waste and 100% kitchen waste. The split weaned heavier half piglets (T2) and lighter half (T3) were again distributed 3 subgroups and fed with same as control groups. All the selected animals were housed on similar concrete floored pens provided with separate feeder and water facility with a run area behind. After 12 weeks, 4 males were selected and reared upto 60 ± 5 Kg from each subgroup for studying the carcass traits. Treatments had no significant effect on live weight, carcass weight, carcass length, Bach fat thickness. But significant (P<0.01) effect was observed on dressing percentage and loin eye area. Dressing percentage was highest in T2 (70.56±0.64) compared to T1(67.24±0.74). Loin eye area (sq.cm) was significantly higher in T1 (39.67±1.2). Diet had highly significant (P<0.01) effect on live weight, fasting weight, head, carcass weight, back fat thickness, belly, loin and ham but dressing percentage, carcass length and picnic had significant (P<0.05). Hence, based on the study it is advisable to feed pigs with concentrate and kitchen waste diet to get maximum economic value due to good carcass quality.
Mapping the Global Research Trends of Renewable Energy -Biogas from Animal Dung: A Bibliometric Critical Research Analysis
Biogas provides renewable, eco-friendly energy alternative to fossil fuels, supports sustainable waste management and addresses the global energy challenges. The bibliometric analysis explores the global research trends in biogas/biofuel from 2000 to 2024, indexed in the Scopus database. The documents obtained were 744 from 334 sources, with an annual growth rate of 16.91 per cent. India, Indonesia, and Nigeria are leading countries in research output, reflecting significant contributions in this research area. The analysis also reveals robust regional and international collaboration networks, particularly in Southeast Asia, Africa, and South Asia, facilitating knowledge sharing and innovation. The most frequent words/terms like biogas (267 occurrences) and anaerobic digestion (171 occurrences), co-digestion (73), reflecting the biogas production processes. Terms like "biofuel", "waste management" and “emission” have seen a surge in the recent years, indicating an increased focus on the broader implications of biogas and waste-to-energy systems. This study has provided valuable insights for researchers, policymakers, and industry stakeholders aiming to develop sustainable waste management and energy production strategies.
From Field to Fact: Analyzing the Communication and Information Ecosystem of Rapeseed-Mustard Farmers
The communication behavior of farmers significantly influences their adoption of agricultural innovations and sustainable practices. This study explores the communication channels and behavioral dynamics of rapeseed-mustard growers in Dhemaji district, Assam, where productivity disparities persist despite the crop's economic significance. A purposive sampling method selected 120 respondents across three blocks, utilizing a pretested interview schedule for data collection. Findings reveal that informal and local community sources, such as progressive farmers (60% regular use) and input dealers (54.17% regular use), are the most preferred channels due to their accessibility, trustworthiness, and practical advice. Government and institutional sources, including extension officers (40% regular use), are valued for their credibility but face challenges like limited reach and awareness. Extension programs such as Kisan Melas (38.34% regular use) and field demonstrations (37.5% regular use) attract moderate participation, emphasizing their role in hands-on learning. Mass media sources like television (41.68% regular use) and social media platforms (46.68% regular use) provide accessible and timely information but are hindered by digital literacy barriers, particularly for emerging channels like mobile apps (21.67% regular use) and the internet (26.67% regular use). The study underscores the need to enhance farmer-extension linkages, improve awareness of digital tools, and customize mass media content to ensure relevance. These insights can inform farmer-centric agricultural policies and communication strategies.
Arecanut based cropping system –A way forward towards improvement of soil quality and profitability of the farming community
Soil quality play a key role in ecosystem functions for sustained crop productivity and promotion of plant health. In recent years, pronounced decline in soil health has been observed globally, resulting from non-adoption of appropriate agricultural practices and land-use approaches. Long-term sustainability of perennial crops like arecanut is threatened by soil degradation resulting from intensive land use practices in small and marginal holdings. Effective utilization of natural resources is encouraged by temporal and spatial arrangement of crops of different height, canopy patterns and root architecture in arecanut based cropping system (ABCS) become effective in improving productivity and also bringing gradual improvement in the soil properties by continuous addition of biomass into soil. Cropping system approach also helps to meet the diversified need of the farmers, increased profitability per unit area and mitigating the risk of mono-cropping. In this context, crop diversification in arecanut plantation with compatible subsidiary crops under six models were evaluated and results indicated significant improved of soil organic carbon (0.60% to 0.86 %), soil reaction (5.43-5.68) status over mono-cropping in the top layer of soil, along with a positive impact on the availability of essential macronutrients. ABCS involving crop combination of arecanut with black pepper, bay leaf, pineapple and colocasia contributed to higher chali equivalent yield (3,761 kg ha-1) from the subsidiary crops. ABCS not only providing additional income from different component crops, but also increased the chali yield even up to 50 % more than arecanut mono-cropping with highest net return per rupee of investment (4.21).
Marine-derived antioxidant fortification of chicken nuggets using Sargassum tenerrimum seaweed
The study envisages assessment of antioxidant activities and fat deteriorative parameters in Sargassum tenerrimum incorporated functional chicken nuggets. Significant reduction of cholesterol content by 32.60% proves its potential to develop low fat meat products. The enhanced antioxidant activities such a DPPH radical scavenging activity, ABST decolourization assay and Ferric acid reducing ability, and the lipid deteriorative parameters such as TBARS, FFA and PV of S. tenerrimum incorporated millet based (7% kodo millet + 3% refined wheat flour) chicken nuggets proves the synergistic impact of S. tenerrimum seaweed in kodo millet based chicken nuggets over the refined wheat flour incorporated nuggets. The results reveal that the S. tenerrimum is a candidate source of functional ingredient in chicken meat nuggets.
