Effect of different levels of synbiotic on productivity and egg quality, blood parameters and hatchability in broiler breeder hens

The present study deals with the effect of different levels of synbiotic on egg production and quality, blood parameters, hatchability and yolk cholesterol in broiler breeder hens. The aim of this study was to determine the best level of symbiotic in the diet of broiler breeder hens. The study was conducted based on a completely randomized design with 4 treatment groups, 2 replicates and 10 controls in each experimental unit. The experimental rations were containing 0 [control S0], 0.05 [S0.05], 0.1 [S0.1] and 0.2% [S0.2] synbiotic. Egg quality and weight were measured daily. Blood parameters, laying rate and hatchability were measured weekly. Yolk cholesterol, ovarian weight and number of ovarian large follicles were evaluated at the end of the experiment. The data were analyzed using GLM procedure. The results showed that yolk index in group S0.1 was significantly lower [p<0.05] than groups S0.05 and S0.2, but was not statistically different from the control [p>0.05]. Also, synbiotic had no significant effect on other egg quality traits, egg weight and hatchability [p>0.05]. Addingy synbiotic supplement to diet reduced significantly the laying rate, ovarian weight and number of ovarian large follicles in the group S0.2 compared with the other groups [p<0.05]. Synbiotic significantly increased plasma glucose concentration [p<0.05], but plasma triglyceride, HDL and yolk cholesterol concentrations were not influenced by dietary symbiotic [p>0.05]. Furthermore, plasma cholesterol concentration [last week] in groups S0.1 and S0.2 were significantly lower than control group [p<0.05]. The results showed that it would be proper to use 0.1% symbiotic in the diet of broiler breeder hens

cross-sectional study of the prevalence of coronary artery disease traditional risk factors in Yazd urban population, Yazd healthy heart project

Coronary artery disease [CAD] risk factors are increasing in developing countries. Previous studies have shown a high prevalence of CAD risk factors in Iran but Geographical prevalence is not uniform. The present study was performed to determine the prevalence of CAD risk factors among Yazd urban population. This cross- sectional study performed in 2004, comprised a total 2000 Yazd citizens [1000 males], and the corresponding data were recorded in questionnaires carrying 500 items. About 85% of Yazd citizens had at least one and 61.1% had at least two coronary artery risk factors. The following data in brackets refer to the males and females respectively. The present study showed obesity in 16.38% of Yazd citizens [9.2 and 24.2%]. The prevalence of hypercholesterolemia 12.1% [10.6 and 13.8%], dyslipidemia 58.5% [59% and 57.6%], high blood pressure 25.6% [27.5% and 23.5%], diabetes mellitus 11% [10.48% and 11.5%], impaired glucose tolerance test 8.5% [7.9% and 9.1%] and cigarette smoking 13.12% [24.45% and 0.5%]. Also 43.3% of men and 62.05% of women had excess weight. The prevalence of hypercholesterolemia, dyslipidemia, diabetes mellitus [DM], hypertention [HTN], and abdominal obesity increased significantly with age [P< 0.005]. The prevalence of obesity, abdominal obesity, hypercholesterolemia and DM were significantly higher in women. Yazd did not carry the highest levels of risk factors in Iran, but the present study showed excess weight, dyslipidemia and HTN were the most prevalent risk factors found in this region. Thus it is recommended to consider the preventive and therapeutic measures as the major health priorities in this area

Prevalence of traditional coronary artery disease risk factors in Yazd urban population: Yazd healthy heart project

Coronary artery disease [CAD] risk factors are increasing in developing countries. Previous studies have shown a high prevalence of CAD risk factors in Iran but geographical prevalence is not uniform. We performed this study to determine the prevalence of these risk factors in Yazd province, central Iran. In this cross-sectional study, a total of 2000 participants, 1000 men and 1000 women among Yazd citizens, were surveyed and data was recorded in a 500- item questionnaire. About 85% of Yazd citizens had at least one and 61.1% had at least two coronary artery disease risk factors. The present study showed that 16.38% of Yazd citizens were obese [9.2% in men and 24.2% in women], and 43.3% of men an d62.05% of women had excess weight. Prevalence of hypercholesterolemia was 12.1% [10.6 in men and 13.8% in women, respectively], dyslipidemia 58.5% [59% and 57.6%, respectively], high blood pressure [HTN] 25.6% [27.5% and 23.5%, respectively], diabetes mellitus [DM] 11% [10.48% and 11.5%, respectively], impaired glucose tolerance 8.5% [7.9 and 9.1%, respectively] and cigarette smoking 13.12% [24.45% and 0.55, respectively]. The prevalence of hypercholesterolemia, dyslipidemia, DM, HTN, and abdominal obesity increased significantly with age [p<0.005]. The prevalence of obesity, abdominal obesity, hypercholesterolemia and DM was significantly higher in women. Excess weight, dyslipidemia and HTN were the most prevalent risk factors in Yazd. Although Yazd did not have the highest levels of risk factors in Iran, but the findings showed that Yazd is one of the "at risk" cities with regard to prevalence of risk factors. Preventive and therapeutic programs should thus be considered as a major health priority in Yazd

[Effect of terbutaline on performance and some blood biochemical parameters of broiler chicks]

To study the effects of different levels of beta-adrenergic agonists on performance and some blood biochemical parameters of male and female broiler chicks. Factorial study [5treatment x 2 sexes] as completely randomized design. Three hundred Cobb male and female broiler chicks. Twenty one day old chickens were fed with 0, 5, 10, 15 and 20 mg terbutaline/kg of diet for 3 weeks. After then, performance[Feed intake, body weight gain and feed conversion ratio], weight of whole body and carcass of chicks and the concentration of serum glucose [GLC], cholesterol [TC], triglycerides [TG], creatine kinase [CK], glutamic oxaloacetic transferase [GOT] and blood urea nitrogen [BUN] of chicks were determined at the end of experiment. Analysis of Variance of the data and Duncan's multiple range tests. While different levels of terbutaline had not any effect on the body weight gain of chicks, feed conversion ratio of the roosters reduced in response to 5 and 10 mg terbutaline /kg the highest weight of the whole body and carracas of male and female chiks were seen with mg terbutaline kg of diet. Increased dietary level of terbutaline made increase in the concentration of GLC. The highest concentration of blood TC and TG were seen by 10 mg terbutaline. Different levels of terbutaline had not any effect on the concentration of CK, GOT and BUN. Results showed that 5 mg terbutaline /kg in grower diet made increase in whole body and carcass weight of male and female broiler chicks. Furthermore, it improved the feed conversion ratio in roosters
