Abstract

Objective: The orange-red spectrum of the skin of electric yellow (Labidochromis caeruleus) is one of the idealistic and necessary schemas sought by aquarists and commercial producers. In this study, the effect of live foods meal on the skin coloration of juvenile electric yellow was examined. Methods: 270 fish with an average living body weight was 0.42 ± 0.11 g, and average total length was 3.3 ± 0.35 cm. Their sex was not taken into consideration. . The fish were fed twice in the morning and afternoon by 3-5 percent of the biomass for 8 weeks. The six different treatments (three replicates/treatment) used in the experiment were used. Skin color was measured in below the dorsal fin of all fish. Measurements were recorded at the end of the feeding trial using a Konica Minolta Chroma Meter CR400. Results: At the end of the trial, the carotenoid supplemented diets significantly increased the values of redness (a*), yellowness (b*), and chroma (C*), and decreased the values of lightness (L*) and hue (Hoab) on the tail, body, and head areas (p<0.05). luminosity (L*) and hue (H°ab) were less in fishes fed the diets with live foods and astaxanthin than in fishes fed the control diet with no pigment sources (p<0.05). yellowness (b*), and Chroma (C*) were greater in fish fed the culex and were less in fish fed the control diet(p<0.05). Results show that live foods used in this trial can be used as an alternative natural carotenoid source in electric yellow diets.

Abstract

Objective: The objective of this study was to investigate the pathological alterations of methionine for chicken embryo.In recent years, amino acids are used in veterinary medicine for many purposes. They injected into hatching eggs to increase chick body weight and performance at hatch, but the adverse effects of amino acids have always been a major concern. There is scant information available about the pathological alterations of amino acids in the chicken embryonated eggs. Methods: Fertile chicken eggs were divided into two equal treatment groups as follows: phosphate buffered saline-injected group and methionine-injected group whose individuals were injected with a methionine solution at a dosage of 10 mg per Kg egg-weight. Embryos were reincubated post-treatment and allowed to develop until day 18 after which; they were examined for macroscopic and microscopic lesions. Results: The germination of inoculated seed was significantly reduced, germ tubes of microconidia penetrated all parts of the thick, complex seed testa, and seed contents were destroyed. Pathogenicity tests indicated that F. solani caused lesions of black soft rot and complete deterioration within 5-7 days (100%). They also attacked Orobanche seeds, arresting their germination and causing maceration of non-germinated and germinated seeds after 5-7 days of incubation. This is the first investigation of the effects of F. solani on host plant interactions with broomrape in melon.

Abstract

Objective: Estimation of genetic parameters for Kleiber ratio (KR) and genetic trends for pre-weaning weights of Arabi sheep has not been previously conducted. Methods: Data and pedigree information were collected at the Khuzestan Ramin Agricultural and Natural Resources University, Animal Science Research Station, located in southwest Iran, from 2001 to 2008. (Co)variance components and corresponding genetic parameters were estimated using the restricted maximum likelihood procedure by excluding or including maternal genetic or maternal permanent environmental effects. Six animal models were fitted to optimise the model KR from birth to weaning, which is defined as the ratio of growth rate and metabolic rate and can be utilized as an indirect selection for feed conversion. Moreover, three-trait analyses were performed using the most appropriate models obtained in single-trait analyses on the basis of Akaike’s information criterion. Results: Direct heritability (h2d) estimate of 0.11 was obtained and maternal permanent environmental effects (pe2) contributed 10% of the total phenotypic variation for KR. Genetic trends for weight at birth and weaning were obtained by regression of average breeding values, on birth year. Direct genetic trends were positive and significant (p < 0.05) for weight at birth and weaning (6 and 24 g per year, respectively). Genetic correlations among traits ranged from -0.52 to 0.89 and phenotypic correlations from - 0.21 to 0. 0.71. Conclusions: Results showed the importance of inclusion of maternal permanent environmental effects in designing appropriate breeding programs to obtain accurate estimates of genetic parameters, and it is sounded that KR is a recommended option in selection program.

Abstract

Objective: Returning crop residue to the soil exerts favorable effects on physical and chemical properties of soil. In fact, the plant residues can affect soil conditions such as pH and important role in soil fertility and cycling of elements in the soil may have. In addition to the role of the organic matter from decomposition of crop residue in increasing the concentration of micronutrients in soil solution is very important. Present research was conducted with the objective of studying the effect of the kind of crop residues: sunflower (Helianthus annnus L. cv. Allstar), sudan grass (Sorghum bicolor L. cv. Speed Feed), trifolium (Trifolium pretense L.) and safflower (Carthamus tinctorius L. cv. Koseh-e-Isfahan), with control on chemical properties of soil and effect on bioavailable of copper. Methods: In this study complete randomized block field experiment, consisting of 3 replications and 5 treatments. After 3 weeks, increasing crop residues, soil samples collected and were used to measure some properties of soil and concentration of Cu in soil. Results: Results showed that crop residues significantly decreased soil pH and the largest increase was observed for Trifolium treatment. EC significantly increased by affected crop residues application. The crop residues significant increased the concentration of dissolved organic carbon (DOC). the largest effect was dependent for Trifolium treatment. The crop residues significant increased the concentration of DTPAextractable Cu. The highest effect was obtained for Trifolium treatment. Therefore, Trifolium residues application decreased the amount of soil pH and consequent increase of DOC which in turn elevated the concentration of DTPA- extractable Cu. Trifolium was the most effective in increasing the phytoavailability of Cu in soil.

Abstract

Molecular farming, or bio-pharming, has recently received much of attention for production of valuable recombinant proteins, with a few already being marketed. The use of whole plants for synthesis of pharmaceutical proteins offers various advantages in economy, scalability and safety over conventional production systems. GM plants are suitable for the inexpensive production of large amounts of functional, recombinant macromolecules, such as blood substitutes, vaccines, anti-cancer antibodies, plasma proteins, enzymes, cytokines and growth factors, and the expressed proteins, ranging from the smallest antigen-binding domains, to full-length, and even multi-meric proteins, are almost comparable to their mammalian counterparts. Delivery of a biopharmaceutical product by direct ingestion of the modified food crops removes the need for purification. Such biopharmaceuticals and edible vaccines can be stored and distributed as seeds, tubers, or fruits, making immunization programs in developing countries potentially cheaper and easier. It is anticipated that this technology has the potential to greatly benefit human health by making safe recombinant pharmaceuticals widely available. Here, we discuss facts, recent developments and perspectives of this field in detail.

Abstract

Objective: Potato is the fourth important food crop after wheat, rice and maize. Shrinkage of food materials has a negative consequence on the quality of the dehydrated product. The main objective pursued in this paper is to investigate the shrinkage amount of potato slices during drying process using vacuum-infrared method. Methods: In this work, the effect of the infrared radiation powers (100, 150 and 200 Watt) and absolute pressure levels (20, 80, 140, 760 mmHg) at different thickness (1, 2 and 3 mm) on bulk volumetric shrinkage were investigated. Results: Data analysis showed that shrinkage percentage decreased with decrease of sample thickness and increase of infrared power. It was found that either thickness or infrared power had any significant effects (P < 0.01) on shrinkage of potato slices in this drying system. The regression model is a three-variable linear that Coefficient of determination is 0.532 and implies that the model can explain 53.2 % of the volume ratio changes.
