This study was carried out to determine the effects of excess dietary Lysine (Lys) and Methionine (Met) on some blood parameters, cholesterol and fat content of carcass and the performance of broiler chicks. In a completely randomized design three hundred male Ross 308 broilers were allotted to five group, each of which included four replicates (15 birds per replicate). The groups received the same basal diet supplemented with Lys and Met (as TSAA) in 0, 10, 20, 30 or 40% more than NRC recommendation. The collected data were analyzed by SPSS software and Duncan's test was used to compare the means on a value of p<0.05. The results indicated that the two highest levels of Lys and Met treatments (30 and 40%> NRC recommendation) led to significant increase in carcass efficiency, breast muscle yield, heart and liver weight and also plasma cholesterol (p<0.05) whereas Feed Conversion Ratio (FCR), crude fat contents of breast and thigh muscles and plasma triglyceride were the least in these two treatment groups (p<0.05). Addition Lys and Met 40% more than NRC tend to significant decrease in body weight gain but there was no significant effect of treatment on cholesterol content of the breast and thigh muscle and also thigh and leg yield. The finding of this experiment showed that increasing Lys and Met to diets of today's broiler in excess of NRC recommendations can improve FCR, abdominal fat deposition, breast meat yield, fat content of the breast and thigh muscles and carcass efficiency and also results reported here support the hypothesis that it is possible to produce poultry meat with different fat content by supplementation excess Lys and Met to diet. © Medwell Journals, 2011.

The transition to the international methodology of cost accounting and statistics has exclude "non production sector" concept, which has been continously applied in the service sector in the practice of Islamic Republic of Iran. During recent years, the service sector has continued to be one of the most developing sectors of the world economy. In most developing countries, as a consequence of restrictions on activities, the private sector is not built on firm grounds and therefore, does not function effectively. On the other hand, the public sector holds a major portion of the economic activities and takes a big part in produceing goods and providing services at a singlerate price: mostly determined by the legal and supervisory authorities. As a result of this practice, in our country, there have been continously raising difference between the final cost of the production and price of goods (service). There are factors affecting to that, among them lack of a suitable system for calculating the final cost and lack of information transparency related to the quality of products are of importance. The research is an applied study in the field of industrial (cost) accounting. It focuses on evaluating the effectiveness of the cost accounting systems and its development in companies with 51% or more state shareholding. As information source, the library study and service of the statistical center of Iran has been used, along with the accounting records of the organizations under study and the state budget data. For collecting empirical data, a set of questionnaire with 30 questions has been used. Different public organizations have been chosen, out of which 100 different professionals were participated in the survey. The questionnaire results then were analyzed to reach a conclusion and make recommendations. In addition, there is also a description of limitations to the study. Source

In this study changes in fatty acids profile during frozen storage at -18°C of Cobia (Rachycentron canadum), caught from the Persian Gulf (Bandar Abbas) were studied. Changes in saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), EPA+DHA/C16, n-3 PUFA/n-6 PUFA (n-3/n-6) and polyunsaturated fatty acids /saturated fatty acids (PUFA/SFA) were investigated during a six- month storage at -18°C. Eighteen fatty acids were found in Cobia, with higher percentage of saturated fatty acids (46.07%), monounsaturated fatty acids (33.72%) and polyunsaturated fatty acids (15.44%). The MUFAs and PUFAs reduced from 33.72 to 26.26% and 15.44 to 10.78%, respectively. Palmitic acid (C16:0, 27.42% of total fatty acids) and stearic acid (C18:0, 12.62%) were the dominant saturated fatty acids. The major unsaturated fatty acids were determined as docosahexaenoic acid (C22:6n3, 5.76%), oleic acid (C18:1n9, 25.76%) and linoleic acid (C18:2n6, 4.38%). As a result of the frozen storage (up to 6 months), marked content decreases were found in fatty acid groups such as monounsaturated, polyunsaturated and n-3 polyunsaturated, as well as in the n-3/n-6 ratio and it means that the nutritional value of Cobia has decreased.
