Atmospheric ammonia is a common problem in poultry industry. High concentrations of aerial ammonia cause great harm to broilers' health and production. For the consideration of human health, the limit exposure concentration of ammonia in houses is set at 25 ppm. Previous reports have shown that 25 ppm is still detrimental to livestock, especially the gastrointestinal tract and respiratory tract...

Nowadays, heavy metal pollution has become a serious environmental problem on global scale. The heavy metals are non-biodegradable in nature, which can easily accumulate in the organisms of lower trophic level, and enter to the human body system through food chain. From this backdrop, the present experiment highlighted the effect of three heavy metals (Cr, Pb, and Mn) in different concentration...

AIM A study was undertaken to investigate the effect of organic zinc (zinc nicotinate, Zn-nic) supplementation (6, 9, and 12 ppm) compared to inorganic zinc (12 ppm) on growth performance, hematology, serum biochemical constituents oxidative stress, and immunity in weaned female Sprague-Dawley rats. MATERIAL AND METHODS A 48 weaned rats (285.20±1.95 g) were randomly distributed to 4 dietary t...

Field experiment was carried out on silt clay loam soils at Regional Agricultural Research station, Chintapalle, Visakhapatnam, Andhra Pradesh during 2018-2020 to study the yield of response rainfed groundnut with different levels Nano particulate zinc oxide application along NPK Fertilizers. The consisting eight treatments, three replications RDF design. Results nano pod showed that (24.36 Q/h...

To explore the relationship between dietary zinc and the natural history of Moloney sarcoma virus (MSV) oncogenesis, BALB/c mice were fed diets which contained four levels of zinc: 100 ppm zinc (designated control); 9 ppm zinc (desig nated marginal deficiency); 5 ppm zinc (designated moderate deficiency); and 2.5 ppm zinc (designated severe deficiency). Moreover, because zinc deficiency is asso...

AIM The main objectives of this study were for comparing the effect of batteries and deep litter rearing systems of domesticated Japanese quail, Coturnix coturnix japonica, on the concentration levels of cadmium, copper, lead, and zinc from the quail meat and offal in Ismailia, Egypt. MATERIALS AND METHODS A total of 40 quail meat and their offal samples were randomly collected from two main ...

BACKGROUND In the present study, blood serum level of metals were determined in malarial patients and compared with those in the normal subjects without complication using Atomic Absorption Spectrometer. METHODS For the determination of these metals twelve intravenous blood samples each from referred malarial patients and a group of normal subjects were collected and immediately centrifuged t...

BACKGROUND Within the framework to control mosquitoes, ovicidal, larvicidal and pupicidal activity of Annona senegalensis leaf extract and its 4 fractions against Anopheles gambiae and Culex quinquefasciatus were evaluated in the laboratory conditions. METHODS Ovicidal test was performed by submitting at least 100 eggs of mosquitoes to 125, 250, 500, 1000 and 2000 ppm concentrations, while la...

Acute and Subchronic Inhalation Toxicity of Chloroform in Rats and Mice: Tatsuya KASAI, et al. Japan Bioassay Research Center—In order to better characterize acute and subchronic toxicities of chloroform and to provide its basic toxicity data for risk assessment of humans exposed to chloroform in work and living environments, mice and rats of both sexes were exposed by inhalation to chloroform ...

Larvicidal activity of acetone and petroleum ether extracts of four plants Murraya koenigii, Coriandrum sativum, Ferula asafoetida, Trigonella foenum graceum and synthetic larvicides Fenthion and Temephos used alone and in combination was carried out against A. aegypti larvae under laboratory conditions. Optimum values were found out by using different concentrations of each plant (ranged 25 pp...
