BACKGROUND: Increase in aquatic production is dependent on raw materials, quality of diet, feed manufacture technology and optimum feed formulation. OBJECTIVES: The aim of this study was investigation and quality control feed of FFT, GFT1 and GFT2 of rainbow trout in farm and fish feed factory producers in Chaharmahal and Bakhtiari province. METHODS: In this study samples of FFT, GFT1 and GFT2 of diets were randomly taken from farm and fish feed factory producers in Chaharmahal and Bakhtiari province. Samples were analyzed for moisture, crud protein (CP), ether extract (EE), ash, phosphorous, TVN, Total count and coliform count. RESULTS: The results showed, diet CP was differs significantly (p<0.05) from many of the feeds. In addition nutrients of CP, phosphorous and EE of diets were differed slightly from rainbow trout requirement and in some cases were lower than instance requirement. The index of TVN that shows free nitrogen, was higher than standard in all samples. Total count and coliform count were different  between some of the other feed factories. CONCLUSIONS: Better management in fish feed factories  must be applied to balance the nutrient requirements  of the rainbow trout diet in different stages of growth, by using fresh, suitable and special feed materials.

Investigation of the structure of equine articular cartilage link protein (LP) from individuals ranging in age from 1 to 15 years identified 3 distinct isoforms having molecular weights of 46,000, 43,000, and 41,000. The relative amounts of each of the 3 isoforms altered with age. The largest form did not change with age; however, amounts of the Mr 43,000 and 41,000 forms increased with increasing age. The results suggested that an accumulation, in the extracellular matrix of cartilage, of these 2 smaller products may have arisen from proteolytic cleavage. The complete amino acid sequence of the protein core was determined from complementary DNA products prepared by polymerase chain reaction amplification of cartilage LP mRNA. The sequence had 96% similarity with human LP and with that of other species for which the primary structure has been determined. This high degree of sequence conservation and the isoform data indicate that extracellular processing of LP occurs by similar mechanisms in various species. At the transcription level, equine chondrocytes were found to express LP as 2 abundant mRNA of 5.0 and 3.0 kb, and a smaller mRNA of 1.5 kb. Processing of the LP mRNA in horses, thus, appears to be similar to that found in other species investigated, and although multiple transcripts are present, the coding region remains unaltered and only 1 protein product is made.

This study sought to determine if sheep suffer neurological symptoms when fed Acacia angustissima leaves, and whether an equivalent amount of 70% acetone extract would have the same effect. In addition, the study tried to determine if treatment of leaves with 70% acetone would destroy the activity of A. angustissima toxins, and whether extraction with 70% aqueous acetone extract would separate two components of a toxic system. Twenty-five Menz lambs were randomly assigned to one of five treatments (1) A angustissima leaves as half the diet, 2) dried extract (70% aqueous acetone) of the same quantity of leaves, 3) a corresponding amount of residues, 4) a recombination of the dried extract and dried residue, or (5) a control diet containing no A angustissima leaves or extract fractions. All animals fed the leaves and the recombined fractions died or were euthanized when they were observed to be dying of severe neurological derangement. None of the other animals showed any neurological signs of impairement. The results of this study indicate that healthy, well-fed sheep can be poisoned by A angustissima, that the toxins are not destroyed by acetone or oven drying, and that severe neurological intoxication requires two components, which can be separated by acetone extraction.

The aim of this study was to evaluate the effect of time of ensiling on chemical composition and in situ degradability of starch of hydrated ground corn (HGC) with medium grain vitreousness. Corn grains harvested at 83% of dry matter (DM) and vitreosity content of 67% ± 3, were dried to 87% DM. Grains were milled into a device with 2 mm sieve, reconstituted to reach 67% DM, and ensiled (density of 880 Kg/m³) for up to 330 days. One HGC sample was collected monthly for in situ determination of composition, fermentation end products and for corn starch degradability. Ensiling time did not affect the DM and crude protein (CP) content of the HGC. However, starch concentration was reduced by 2.4 percentage points at 330 days compared to 3 days of ensiling. Increased concentrations of NH3-N (8.5 times), lactic acid (3.45 times), acetic acid (4.1 times), propionic acid (1.7 times), butyric acid (2.8 times) and alcohol (2.4 times) were observed during the ensiling period. The rapidly degradable fraction (fraction A) and the rate of degradation of the slowly degradable fraction (fraction C) of HGC starch were increased 3.51 and 2.21 times, respectively, during the ensiling period. Conversely, the slowly degradable fraction (fraction B) of the HGC starch was decreased 1.93 times during the ensiling period. The effective degradability of the starch of HGC increased for passage rates by 0.02/h (79.9% vs. 94.5%); 0.05/h (65.9% vs 90.01%) and 0.08/h (56.98 vs. 86.52%) when it was evaluated at 3 vs 330 days of ensiling, respectively. In conclusion, ensiling time affected the chemical composition and increases rumen starch degradability of HGC with medium vitreousness of the grain endosperm.

In this study, the selection of samples from different levels of pastry chains and local markets as well aimed to assess the influence of price and brand name; which may be considered at the moment of cake selection, on the nutritional quality and safety of the final served product.The moisture, ash, protein, fat, fiber, and available carbohydrate contents of 30 cake samples produced locally in Egypt from different brands pastry shops divided into international, national, and local brands were determined. Results explored that the highest average moisture content was recorded for the international brand (45.7 %), followed by the local brand (42.8 %), while for the national brand, it was 40.9%. The international brand samples' results were the highest in protein% (4.8) and the lowest in Ash% (3.5), while the national brand samples were the highest in average fat% (19.5) and the local brand samples were the highest in average carbohydrates% (36.1). Average protein content appeared to be very close in percent throw groups with 4.8, 4.5, and 4 in international, national, and local brands, respectively. Also, the total energy in a piece of cake was calculated by analyzing total fat, protein, and carbohydrate contents. The highest average caloric content was found in national brand samples (317.9 Kcal), 53.1% of this energy content was accredited to fat content. Different studies were subjected to the side effect of pastries on human health all over the world but these studies were slightly deficient in Egypt, our study aimed to determine the nutritional quality of cake samples by finding out the type of fatty acids used in processing through analyzing the fatty acid profile (SFA, MUFA, PUFA & Trans FA), in addition, Lipid Nutritional Quality Indices (LNQI) were evaluated from the composition data of fatty acids.  Data presented in this study showed bad effect of Cream based cakes consumption in Egypt especially from the local brand shops due to its high saturated fatty acid content with the highest incidence of TFA (4.5%) and high caloric value from carbohydrates content (52.8%) especially on high risk people with chronic disorders and eldery. Also it was noticed that the high price of international brand product is in equivelant with its chemical composition and good quality as it is more healthier than other brands.

We analyzed the conentes of 12 types of minerals such as calcium in muscle from various species. Thereafter we ovserved changes of the concetrations according to age, part and sex in major domestic animals. The concentraions of calcium, iron, sodium, potassium, magnesium and zinc were high respectively whilst the content of cobalt, chromium, copper, manganese, molybdenum and nickel were low respectively in the muscle. The concentration of calcium was high in duck and dog but low in pig and horse. Also high level of sodium content was detected in dog and the content of potassium, iron showed high level in horse compared with the content in other animals. In 6 types of microminerals as cobalt, the level of muscle wer no more than 1 ppm showing very low content in all animal, but 2.99+_0.85ppm of copper in duck was an exceptional case. According to the age some species showed small range of variation centering on macrominerals and there was no remarkable change in microminerals. Distribution of minerals was different according to the part and the variation was very diverse compared with other factors such as age and sex. Additionally, the content of mnerals in muscle was higher in female than in male chicken and duck. In conclusion, the difference of the content of minerals according to the species was mainly focused on macrominerals.

Cerebrospinal fluid and serum were obtained from 17 adult, healthy llamas (9 males, 1 castrated male, and 7 females). Osmolality; activities of lactate dehydrogenase and creatine kinase; and concentrations of glucose, sodium, chloride, potassium, total protein, and albumin were determined in serum and CSF. Total and differential cell counts were determined in CSF, and electrophoresis of CSF proteins was performed. Total nucleated cell count was low, 0 to 3/microliter, which is lower than that reported for other domestic species and is similar to values in healthy people. Differential leukocyte percentages were disparate depending on the degree of blood contamination. Blood contamination influenced the percentage of neutrophils and eosinophils in CSF. Samples with few erythrocytes had differential leukocyte distribution similar to that of other species: mostly lymphocytes, fewer monocytoid cells, and scant neutrophils. Older llamas had a few eosinophils in the CSF. Total protein, albumin, and gamma-globulin concentrations in llamas were similar to values in cattle and were higher than values in most domestic species. Glucose concentration in CSF was approximately 40% of the value in serum (nonruminant animals and people typically have CSF glucose concentration that is approximately 60 to 80% of the serum glucose concentration). Sodium and Cl concentrations in CSF were higher than those in serum, whereas K concentration was lower in CSF, compared with serum. Activities of creatine kinase and lactate dehydrogenase in CSF were markedly lower than those in serum, and the ranges of values in this group of healthy llamas were narrow.

Paired CSF and serum samples were obtained from 109 rhesus macaques aged 1 to 18 years. The CSF and serum IgG and albumin concentrations were determined, using radial immunodiffusion; CSF total protein and glucose were determined, using colorimetric methods; and Na, K, and Cl concentrations were determined, using ion-specific electrodes. The CSF protein values were lower than those reported for nonhuman primates, and this finding was confirmed by results of agar gel electrophoresis. Animal age and sex had no significant effects on CSF composition, but serum IgG concentration increased with age. Concentrations of total protein, albumin, and IgG were greater, and concentrations of glucose and potassium were lower in CSF obtained from the lumbar rather than the cisternal site. Composition of CSF was not significantly altered by contamination with blood at values up to 10,000 RBC/microliter. The CSF albumin quotient, IgG quotient, and IgG index were determined and differed markedly from values reported for human beings, indicating that the properties and specificity of the blood-brain barrier may be species-specific.
