32 Abstract Antibiotic growth promoters have been extensively used in the poultry feed to improve weight gain, feed efficiency, lessen the number of harmful bacteria, enhance immunity etc. However, they have role in development of the resistance in the pathogenic bacteria and impose negative impact on the consumers due to residues. Medicinal plants are the best replacement option of ABGP. Garli...
A study was conducted to evaluate the effects of energy and protein levels of maternal diets on growth, some blood parameters, health, and performance of baby goat kids at first month of life. On 95 d after successful mating, 28 synchronized singleton pregnant Sistani goats were randomly allocated to four treatments including 1) low protein and low energy (LPLE), 2) high protein and low energy ...
Starvation periods of fish in during the developmental stages on growth indices and blood factors can be affected. The effects of compensatory growth on growth indices and physiological responses (glucose, total protein and cholesterol), study for 8 week investigated in Juveniles of common carp (Cyprinus carpio). The fish were divided in 4 experimental groups with initial weight (13/88±0/88 gr)...
studies have demonstrated that plant extracts possess various biological characteristics, including immunomodulatory activity. heracleum persicum desf. (apiaceae), a medicinal plant native to iran, was studied for its immunomodulatory activity. immunomodulatory activity of different doses of an aqueous extract of h. persicum, was evaluated in female swiss albino mice. mice were treated with thr...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
Native poultry is a valuable genetic source with high resistance against diseases providing an important subject for breeding programs. The non-linear mathematical modeling of the growth pattern may partly explain the relationship between requirements and body weight to precise feeding that plays a vital role in the animal enterprises. A study was conducted to compare five non-linear models inc...
The study calculates the fork-length to round weight (L-W) relationship and condition index (K) of fattened bluefin tuna for 6-7 months in a tuna farm in western Greece and compares these morphometric parameters with those of wild bluefin tuna using the set of measurements obtained in the context of the EU-funded research projects REPRO-DOTT & SELF-DOTT. The L-W relationship and K values found ...
the application of nanotechnology in drug delivery and a variety of supplements is very impressive. in this regard, the use of this knowledge can be effective in the performance of medicinal plants in aquaculture. in the present study aloe vera was extracted and its nanoparticles were produced. three levels of aloe vera nanoparticles in siberian sturgeon (acipenser baerii) were evaluated for th...
