Item The effect of various carbohydrate sources on half-life, biological traits and microbial flora of the bee digestive system(Bursa Uludağ Üniversitesi, 2019-03-07) Karimi, Hamid Reza; Abadi, Saeed; Shahryar, Habib Aghdam; Teli, Abdulahad Shaddel; Nobar, Ramin SalamatdoustThe research was conducted in a completely randomized design in 12 treatments and 6 replicates in an incubator on Apis Mellifera Meda, which started from the first half of May 2018 and was carried out until the end of July at the Isfahan Agricultural Research Center. The treatments included white sugar, brown sugar, honey as control and corn liquid fructose, corn starch, wheat starch and potato starch in sweet dough, which was tested in proportion of 15% and 30%. The measured traits consisted of feed intake, half-life, carcass protein and lactobacillus and Coliform content of honey bees’ digestive systems. The results indicated that the treatments showed a significant difference in all traits (p <0.05) and the highest feed intake was related to honey treatment (42.50 g) and the lowest amount of sweet dough containing 30% wheat starch (21.50g), the lowest 50% mortality rate was related to sweet dough (40 days) and the highest mortality rate was related to sweet dough containing 30% corn starch (10 days) .According to the results, sweet dough treatments containing 15% starch in total showed better results than sweet dough treatments containing 30% starch.Item Effects of exposure to 50 hz electromagnetic fields during ıncubation on some of serum biochemical measures in newly-hatched chicks(Uludağ Üniversitesi, 2012) Lotfi, Alireza; Shahryar, Habib Aghdam; Rad, Mohammad NarimaniThe aim of present study was to determine the effect of intermitted exposure to 50 Hz, 0.5 mT electromagnetic fields (EMF) during different periods of incubation on serum biochemical parameters (glucose, total cholesterol, triglyceride, uric acid and iron concentration) in newly-hatched chicks. Experimental groups were: group 1 (control), with normal incubation process and without any exposing to EMF; group 2 included eggs exposed to 50Hz, 0.5 mT EMF, 2 h daily for 0-7 day of incubation; group 3 included eggs exposed for 2 h daily from day-8 to -14 of incubation; group 4; included eggs exposed from day-15 to -21 of incubation, and group 5 included eggs exposed from day-1 to -21 of incubation (whole incubation period). Incubation condition with exception to EMF exposing, was similar for all groups. At EMF exposure time, eggs were transferred to EMF emitter set and after exposure time, eggs were transferred to their rows (setter). Blood samples obtained from newly hatched chicks were analyzed. exposure to EMF: 50 Hz, 0.5 mT during embryonic life didn’t has considerable effect on total cholesterol, triglyceride, uric acid and Fe of newly hatched chicks. In present study, the only measure with significant changes was glucose concentration that had difference between group4 or 5 (exposed at 3rd or whole incubation period) and control group (P<0.05). It was concluded that exposure to EMF: 50 Hz, 0.5 mT during incubation with exception to glucose declining at late embryonic life (exposure at 3rd week), didn’t has any significant effect on plasma total cholesterol, triglyceride, iron or uric acid in hatched chicks.Item Evaluation of nutritional effects of different levels of enzymatic fructose and sugar syrup on the half life and bacterial flora of the bee digestive system(Bursa Uludağ Üniversitesi, 2020-05-27) Dehkordi, Majid Sadreriahi; Abadi, Hamid Reza Karimi Saeed; Shahraki, Amir Davar Foroozandeh; Esfahani, Mohammad Behjatian; Jazi, Masoud Boroumand; Teli, Abdulahad Shaddel; Shahryar, Habib AghdamThe research was carried out in a completely randomized design with 6 treatments and 6 replications in the bee incubator (Apis Mellifera Meda) from the second half of May 2019 till the end of July 2018 in Isfahan Agricultural and Natural Resources Research Center. In order to evaluate the nutritional effects of different levels of enzymatic fructose (0, 10, 20, 30, 40 and 50%) and sugar (50, 40, 30, 20, 10 and 0%) on the longevity and bacterial flora of the bee digestive system, mean comparison between experimental treatments showed that the lowest longevity and half-life between experimental levels was related to treatment with 50% fructose (P <0.05). The longevity of control treatment and treatments with 10% fructose were significant at 38.8 and 32.2 days, respectively, and the lowest feed intake was also observed at 50% fructose (P <0.05). Maximum and minimum Lactobacillus bacteria population in the bee digestive system inside cage were 10% fructose with 8.30(log CFU/g) and 50% fructose, respectively. The bacterial population of coliforms in the digestive system of bees inside the cage was the lowest with 10% fructose and the highest with 50% fructose (P <0.05).Item Possibilities of inclusion of saccharomyces cerevisiae as replacement for fish meal or poultry meat by-product in broiler chicken diet(Uludağ Üniversitesi, 2012) Shahryar, Habib Aghdam; Ahmadzadeh, Alireza; Lotfi, AlirezaThe aim of this experimental work was to evaluation of efficiency of dietary inclusion of SCY as replacement for fish meal or poultry meat by – product in broiler diet. A completely randomized design with five treatments, each with three replication of twelve chicks each was conducted from 7-49 day of age to investigate the effects of Saccharomyces cerevisiae yeast (SCY) as replacement with fish meal or poultry by – product protein on broiler performance. Treatments include: 1 control group 2 and 3: yeast in replace with 40 and 60 percent of fish meal protein 4and 5: yeast in replace with 40 and 60 percent of poultry by-product protein. Inclusion of SCY as fish meal replacement in two levels (treatment 2 or 3) didn’t have any negative effect on feed intake, weight gain or feed conversion ratio. Also dietary inclusion of SCY as replacement of poultry meat by-product (40% of poultry meat by-product proportion in diet) didn’t have any negative effect on performance. Only inclusion of 60% SCY as replacement for poultry meat by product had significant negative effect on performance includes feed intake, weight gain and feed conversion ratio (P<0.05).The results of this study indicated the use of SCY with 60 percent replacement of fish meal protein and poultry by-product protein can improve meat quality and broilers performance.Item Seasonal incidence of some economic bee diseases (Varroosis, Nosemosis and American Foulbrood) in honey bee colonies of Northwestern Iran(Uludağ Üniversitesi, 2011) Lotfi, Alireza; Shahryar, Habib AghdamThe aim of this review is to inform about the status of three economic bee diseases (Varroosis, Nosemosis and American foulbrood) in an important honey producing region, eastern Azerbaijan province (Northwestern Iran). These reports are based on colonies analysed for possible occurrence of these diseases. The major bee disease in the region is varroosis. Lowest rate of varroosis spread was in spring (7.72%) and it increases in the following seasons respectively and the highest rate was occurred in March (44%). Because of cold and semi-arid climate in northwestern Iran (such as eastern Azerbaijan province), Nosema apis has lower prevalence, but it can be hazardous at spring with about 59% incidence rate. About American foulbrood (AFB) 5.8% total infection rate was observed, AFB infection was started in May with highest incidence rate (17.3% of apiaries) and finished in July with 1%. With attention to these findings and reports of local veterinary organization, varroosis as the major bee disease in this region via impairing of bee population and stability in the colony, make susceptible conditions for secondary infection with Nosema apis at next spring.
