Exogenous proteolytic enzyme supplementation is required in certain disease conditions humans and animals due to compelling reasons on use of more plant protein ingredients profitability animal feed industry. However, limitations their utility diet are imposed by pH specificity, thermolabile nature, inhibition a variety factors the possibility intestinal damage. For enhancing efficacy safety exogenous trypsin, an efficient chitosan (0.04%) nanoencapsulation-based controlled delivery system...

The effect of dietary fish protein hydrolysate (FPH) at inclusion levels 0% (control), 5% (FPH5), 10% (FPH10) and 15% (FPH15) (w/w) on growth, digestive enzyme activity, immune response antioxidant status striped murrel, Channa striata (4.18 ± 0.04 g), was evaluated. FPH had significantly increased weight gain (WG), specific growth rate (SGR), efficiency ratio (PER) decreased feed conversion (FCR) compared with the control (p < 0.05). activities enzymes (amylase total protease) transaminases...

The present study investigates the diversity and abundance of plankton, alongside physicochemical parameters Azhagankulam Pond in Kurichikulam near Sankar Nagar, Tirunelveli district, India. Zooplankton feed on phytoplankton, helping to regulate algal populations preventing uncontrolled growth. They respond quickly environmental changes, making them valuable bioindicators water quality, including factors like pH, dissolved oxygen, nutrient levels. Their composition vary with organic...

Exogenous nucleotide supplementation during times of rapid growth and stress is preferred because de novo synthesis insufficient energetically a costly process. To overcome inefficient utilization dietary nucleotides due to intestinal cell repulsion dependency on pH, an efficient controlled delivery system based chitosan nanoparticles (NPs) was developed. The effects these (0.2% 0.4%) RNA-loaded NPs (Chitosan: RNA ratio 2:1), 0.4% bare RNA, 0.8% productive efficiency (growth rate, feed...

Wave fields, both measured and forecast during the very severe cyclone Phailin, are discussed in this communication. Waves having maximum height of 13.54 m were recorded at Gopalpur, landfall point cyclone. The observed significant wave heights matched well Gopalpur with correlation coefficient 0.98, RMS error 0.35 scatter index 14%. Forecasts also validated open ocean found to be reliable (scatter < 15%). study revealed presence Southern Ocean swells a peak period 20-22 sec hitting coast...

Background: Population aging is a worldwide phenomenon. In India, according to the 2001 Census, elderly population (60+ years) accounted for 77 million; however, has crossed 100 million mark Census 2011. Aging results in generalized deterioration of most vital organs and systems, thereby leading lesser effectiveness physiological functions an increase risk factors that leads various diseases. Objective: To assess morbidity pattern study health-seeking behavior rural geriatric Varanasi...
