Higher percent weight gain (2665 g), specific growth rate (2.76±0.5 % day-1), best feed conversion ratio (0.14), condition factor (4.1), viscerosomatic index (7.1), hepatosomatic index (1.4) were significantly (P< 0.05) higher of fish treated with the artificial diet as compared to those in control ponds. Lengt...
Influence of Nitrogen Fertilizer on Nitrate Contents of Plants: A Prospective Aspect of Nitrate Poisoning in Dairy Animals
Ghazunfar Rashid1, Muhammad Avais1, Syed Saleem Ahmad1, Muhammad Hassan Mushtaq2, Rais Ahmed3,*, Mahboob Ali1, Muhammad Naveed-ul-Haque4, Mehtab Ahmad5, Mumtaz Ali Khan1 and Naimat Ullah Khan6
...bnormally high levels of nitrite. In conclusion, nitrate contents were higher (>5000 ppm) in stem parts of common livestock fodder harvested in early morning and therefore, high level of nitrite found in blood of animals fed with the fodder containing high nitrate contents. This high level of nitrates in fodder crops constitutes a threat to the health and productivity of dairy animals.

... quality (total ammonia, nitrite, and nitrate concentration), heterotrophic bacteria, and vibrios during different P. monodon stages(nauplii, zoea, mysis stage, postlarvae). In ponds 1, 2, 3 and 4, the survival rates were significantly lower but the nitrite concentration and vibrio numbers (before mysis stage) were considerably higher than those in other ponds (P < 0.05), indicating that
The Status of Water Quality in Various Fish and Shrimp Farms of Sindh Province, Pakistan: Abundance of Planktonic Biomass in Relation to Physicochemical Properties of Pond Water

...ture, nitrate, salinity, nitrite, pH, total hardness, dissolved oxygen (DO), chlorophyll-a and phytoplankton-density during the period from March, 2015 to June, 2016. The chlorophyll-a concentration was determined by using the acetone extraction technique. Ponds water sample (50 liters) was filtered through plankton net of 20 µm pore size and preserved in 4% formaldehyde for the analysis of phytoplankton. Subsequently, the phytoplankton were counted unde...
Assessment of Water Quality Parameters for Aquaculture uses: The Case of Guder River, Main Tributaries of Blue Nile, Ethiopia

...kit was used to evaluate nitrite and ammonia levels. The result revealed a high level of alkalinity (66.3±39. 1mg. L-1) at downstream and lowest concentration (58±40mg.L-1) was found in the middle stream. The upper stream has a high CO2 concentration (14±3.6mg.L-1) while the middle stream has a low CO2 concentration (9.4±0.77mg.L-1). The maximum chloride content (28.7±2.6 mg. L-1) was found at downstream, whereas the lowest (...

... addition of 0.3% sodium nitrite (P2), 2.5% chitosan (P3), and 0.6% bacteriocin (P4). All samples were stored at freezing temperatures for 30 days. Data were analyzed statistically using analysis of variance, and differences between treatments were analyzed using DNMRT at the 5% level. The results showed that the application of various preservatives might impact the quality of fishballs during the first 30 days of frozen storage. Even though the chemical and s...
Utilization of Ultrasonic Waves to Reduce Nitrite Levels in Edible Bird Nest

Deny Juniwati1, Hadri Latif2*, Trioso Purnawarman2, Zhang Shuqi3

 

... (PRC). The provision of nitrite levels is less than 30 ppm for raw cleaned EBN, so the EBN is washed to reduce it. The industry generally washes EBN with reverse osmosis (RO) water, but this method does not significantly reduce nitrite levels. Therefore, an alternative method is needed. This study aimed to analyze the effect of washing using RO water combined with ultrasonic waves to reduce nitrite<...
Nitrite Level and Rehydration Capacity of Edible Bird’s Nest Heated at Commercial Sterilization Temperature

Satya Fahriani1, Hadri Latif2*, Herwin Pisestyani2, Zhang Shuqi3, Suyanto Chen3

...udy aimed to examine the nitrite level and rehydration capacity of EBN after undergoing a retort process. The samples were 24 raw uncleaned white EBN from 4 swiftlet farmhouses (SFHs) collected using purposive sampling. Two SFH from Sanggau District, West Kalimantan Province, Indonesia. Two SFH from Pekanbaru City, Riau, Indonesia. 12 pieces of samples were not heated, while the other 12 pieces were heated at retort temperature. The sample’s
Ethanol Extract of Gentiana straminea Maxim Displays Anti-Hypoxia Effects by Regulating Antioxidant Enzymes and Energy Metabolism

...ric hypoxia test, sodium nitrite poisoning test, isoproterenol poisoning test, and acute cerebral ischemic hypoxia test. Subsequently, the content of superoxide dismutase (SOD), malondialdehyde (MDA), and activity of total antioxidant capacity (T-AOC), catalase (CAT) in mice liver were measured; while SOD and MDA contents and activity of T-AOC, CAT, Na+-K+-ATPase, Ca2+-Mg2+-ATPase, pyruvate kinase (PK) and phosphofructokinase (PFK) in mice brain were evaluated...

... and 17. The supernatant nitrite/nitrate (NOx) concentration was assessed after the reduction of nitrates to nitrites using the Griess reaction. Results revealed three distinct periods during postnatal development. In the first period, between PND1 and PND4, NO expression in both sexes increased, reaching a peak at PND8. The second period (PND8 to PND10) showed a slight decrease in NO expression. In the last period (PND11 to...
