This study was conducted to evaluate the effect of different levels of herbal methionine in low protein diet on performance, carcass characteristics, immune response and some blood parameters in broiler chickens. In this experiment 240 day-old Ross 308 mixed broiler chicks were randomly divided into 6 groups with 4 replicates and 10 birds each in a completely randomized design. Treatments inclu...
in this study, the effects of culban seed (vicia peregrine l.) on live body weight, feed intake, feed efficiency, egg production, egg quality characteristics, egg yolk fatty acid profiles and yolk cholesterol content in laying hens were investigated. the experiment consists of seven treatment groups with ten replications containing one laying hen in each and for 32 weeks old seventy laying hen ...
l- carnitine has been recognized as a new and important dietary supplementation, essential for human and animal nutrition. this study was conducted to evaluate the use of dietary l- carnitine supplementation and its effects on the growth (body final weight, daily growth rate (dgr), feed efficiency (fe), feed conversion ratio (fcr), daily feed intake (dfi), protein efficiency ratio (per), lipid...
diphtheria is a fatal disease caused by exotoxin of corynebacterium diphtheria . this toxin consists of two chains, catalytic chain (a) and binding (b) chain. by binding chain (b), the toxin binds to its receptor on numerous body cells such as myocardial, kidney and peripheral nerve cells. after entering, catalytic chain (a) inhibits protein synthesis and finally can cause cell dea...
An experiment was carried out to investigate the effects of different levels of energy (2700, 2900 and 3100 kcal/kg) and protein (13, 14.5 and 16 %) on laying performance of Fars native hens during the first phase of production. Two hundred and sixteen 25-week-old native pullets were put into fifty four groups of similar live weight (994 ± 169 gr) of four chickens, which were randomly allocated...

Animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. Nitrogen has been identified as the foremost source of nonpoint water pollution and the potential negative impacts of N have become an area of public concern. protein degradation from feed ingredients is an important factorinfluencing AA supply to the duodenum. Ruminal proteolysis...

background: production of tissue plasminogen activator protein (t-pa) in prokaryotes systems has many problems such as the lack of active protein production, multiple purification steps, and renaturation process which has been shown to be costly and time-consuming. methods: in this study, reteplase which is the nonglycosylated active domain of t-pa was used to transform top10 escherichia coli (...
Abstract Background and Objectives: Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease. Mucosal feeding of myelin basic protein binding to the cholera toxin B subunit can reduce the intensity of the immune response in MS patients. Expression system, the domain composition of the fusion protein, accessibility of two domains, codon adaptation index (CAI) and GC contents are v...
