The objective of this study was to compare zinc sources and levels of supplementation on laying hen performance. Bovan White Leghorn hens were fed one of six dietary treatments in a 2x3 factorial arrangement consisting of two zinc sources (Availa®Zn or zinc sulfate) and three levels (40, 80, or 120 ppm). Treatments were randomly assigned to 48 cages with five hens/cage. Blocks provided eight re...
A total of 480 pigs (PIC 327 × 1050; initially 107.4 lb) were used to determine the interactive effects of supplemental Cu, Zn, and Ractopamine HCl on finishing pig growth performance, carcass characteristics, and antimicrobial susceptibility of enteric bacteria. Dietary treatments were arranged in a 2 × 2 × 2 factorial with main effects of added copper sulfate (CuSO4; 0 vs. 125 ppm Cu), added ...
Levels of selected heavy metals (Pb, Co, Cu, Ni, Zn, Mn and Cd) in the heart and kidney tissues of parrot fish, collected from the Arabian Gulf, Eastern Province of Saudi Arabia, were determined by wetdigestion based atomic absorption method. The results showed that accumulation pattern of analyzed metals in the kidney tissues followed the order; Zn > Cu > Co > Pb > Ni > Mn > Cd. In the heart t...
In the present study, heavy metal pollution and accumulation was investigated in an important mangrove plant, Avicennia officinalis grown in the polluted sites of Kanjurmarg creek, Mumbai. This creek is a location of discharge of influent and waste of some domestic industries. The analysis was done in leaves and stem of the plant as well as in water and soil for the heavy metals like Zinc ( Zn)...
An experiment involving 25 experiment stations in the North Central and Southern regions (NCR-42 and S-288, respectively) was conducted to assess the degree of uniformity of diet mixing among stations and to assess the variability among station laboratories in chemical analysis of mixed diets. A fortified corn-soybean meal diet was mixed at each station using a common diet formula (except for v...
The aims of this study were to determine the feeding effect of diets containing different ratio of ω-3 and ω-6 fatty acids and organic Zn on egg production and quality of Magelang duck. A total of 90 ducks of 20 weeks old were randomly divided into 18 experimental units by assigning a completely randomized design with 6 treatments and 3 replications. There were 6 dietary treatments, namely 1) r...
A study was conducted to investigate Fe requirements of broiler breeders. One-hundred-fifty-six Cobb 500 broiler breeder hens were individually placed in electrostatically painted cages at 22 weeks. The study was composed of an adaptation phase, in which hens were fed corn-soy-wheat bran diets until 35 wks. An Fe deficient mash diet (24.6 ppm Fe) was provided from 35 to 46 wk in order to induce...
The substantial of mineral ingredients in honey may symbolize the existence of elements in the plants and soil of the vicinity wherein the honey was taken. The aim of this study was to detect the levels of 13 elements (Potassium (K), Sodium (Na), Calcium (Ca), Iron (Fe), Zinc (Zn), Cadmium (Cd), Copper (Cu), Manganese (Mn), Lead (Pb), Nickel (Ni), Chromium (Cr), Aluminum (Al), and Selenium (Se)...
The aim of the study was to determine whether using chemical and radiochemical analysis of lake sediments can highlight changes in the climate. Also it was studied whether human impact on the environment can be observed and to what extent such changes are in agreement with historical data. Samples of 16 cm thick sediment cores from the Smreczynski Staw Lake were collected and divided into 1 cm ...
