The aim of this study was to determine the effects of in ovo injection of Saccharomyces cerevisiae (SC) to fertile Ross 308 broiler eggs or dietary supplementation on growth performance, internal organ development, gut histomorphology and cecum microbiota during 14 d of growing period. This study was designed as 2×2 factorial experimental design. Fertile 92 Ross 308 eggs were injected with SC solution 0.2ml at 18d of hatch and 90 eggs non-injected as control, afterward dietary SC supplementation was applied during the 14 d to broiler diet. In this study, 160 broiler chicks were used in four treatment groups at 10 replicate for each treatment group and 4 chicks for each replicates. Treatment groups were A) in ovo SC injection + dietary SC supplementation, B) in ovo SC injection + basal diet, C) no injection + dietary SC supplementation, D) no injection + basal diet as control. Live weight, feed consumption, feed conversion ratio and gut histomorphology, caecum microbiota, internal organ weight were recorded at 14 days of age. Live weight gain increased in C group than in the D group. Feed consumption, feed conversion ratio and internal organ weights were not affected by the treatments. Villi length and villi width increased in A group among the other treatment groups in jejunum, villi length increased in A and C groups among the other groups in ileum. Villi length/villi width ratio increased in A group than in the D group in ileum, was not different in jejunum. LAB counts in caecum were higher in A group than those of C and D groups, but was not different from B group. Enterobactericaea count was lower in A and B group than in the D group, was not different from C group. To conclude, results showed that dietary Saccharomyces cerevisiae supplementation increased broiler growth at 14 day by increasing villi development and improving gut health.

Agricultural technologies are seen as an important route out of poverty in most of the developing countries. However, the rates of adoption of these technologies have remained low in most of these countries. This study aim at shedding some light on an evaluation of climate mitigation agricultural adoption technologies, and its contribution to rural livelihood outcomes in Gurawa district using cross sectional data collected from randomly selected 180 sample households during the 2016 crop production season. Multivariate probit and Propensity score matching was used to identify impacts of adoption technologies, and to identify factors affecting smallholder farmers’ multiple technology adoption decisions. The results showed that the probability of adoption of agricultural technologies are influenced by several factors: family size, economical active members, education level, age of the household head, social status, soil fertility status, distance from extension office, land holding, distance to markets and distance to weather road. The impact evaluation results indicated that on average, the participation household in soil conservation has increased food security status and asset accumulation nearly by 38% and 15%, respectively, however it decreases the rate of poverty nearly by 51 percent. Use of improved seeds increased food security status and decreased poverty rate nearly by 38% and 44%, respectively. On the other hand, use of irrigation technology increased food security status and asset accumulation nearly by 23% and 31.8%, respectively, whereas it decreases the rate of poverty nearly by 29 percent. Similarly, adoption of row planting methods increased food security status and asset accumulation nearly by 28.7% and 15.5%, respectively, whereas it decreases the rate of poverty nearly by 51.5 percent. Therefore, policy makers should give due emphasis to the aforementioned variables to increase adoption technologies and improve the livelihood of the rural households.

2018
Mustafa Yıldırım
In semi-arid regions, unfavorable weather conditions are the most important limiting factors for seed germination. The imbibed or germinating seeds in soil can be dried by hot and dry weather. Thus, seeds can largely lose their germination abilities until the next water uptake (called as ‘alatav’ in Turkish). Before drying, the time of the first water uptake by a seed may be more effective on seed viability at the second water uptake for germination. Therefore, this experiment was conducted to identify the first water uptake rates (WU) of seeds of three bread wheat genotypes (Bezotaja, Kirac and 13-BVD-4) per hour during 50 hours and their germination rates (GR) at the second water uptake after drying the seeds for 3-week in laboratory conditions. The results presented here indicated that the WU and GR were significantly affected by genotypes, imbibition time (T) and their interaction (1% probability level). There was also a significant negative correlation between the WU and GR (r** = –0.9295) at all times studied. Furthermore, the germination ability of Kirac lasted longest (for 38th hour) when the WU reached to 160.24%, and it was followed by Bezostaya and 13-BVD-4 genotypes (63.34% at 37th hour and 152.58% 34th hour, respectively).

Sedef İlk
Phenolic compounds which have many bioactivities such as antioxidant, antimicrobial and also inhibition of quorum sensing-regulated violacein pigment production properties are one of the plant secondary metabolites. The objective of this study was to determine the antioxidant, antimicrobial activity and the inhibition of quorum sensing (QSI) activity by the phenolic extract obtained from strawberry fruits (Fragaria×ananassa cv. ‘Rubygem’). The phenolic content of extract was determined as 3089 μg GAE g fw-1. The antioxidant activity determined through the ABTS+ and FRAP method was 28.4 and 26.2 mmol TE L-1 respectively. The phenolic extract was able to inhibit all the evaluated bacteria by the disc diffusion assay in the range of 3.12–18.36 mm and could inhibit the quorum sensing phenomena in bacteria. The strawberry phenolic extract exhibited high antioxidant capacity, antimicrobial and anti-quorum sensing properties. To our knowledge, this is the first report on the quorum sensing inhibition activity of strawberry fruit extract. The discovery of non-toxic novel compounds within antibacterial and QSI activity could lead to the development of antimicrobial therapeutic agents that can be alternative and complementary treatments against antibiotic resistant bacterial pathogens

In this study, thermal inactivation of Salmonella Enteritidis inoculated to the cake dough and a whole raw chicken was investigated. The cake dough was inoculated with 6.15 log-cfu/g S. Enteritidis then, thermal treatment was applied at 160°C top-bottom fan cooking mode. The initial count of S. Enteritidis showed reductions 1.49 log-cfu/g, 2.06 log-cfu/g and 4.29 log-cfu/g in the samples from the cold point location from the geometric center of the cake at 5, 7 and 10 minutes of thermal treatment, respectively. Although S. Enteritidis is not detected at the end of 15 minutes of heat treatment, the center of the cake temperature has reached 85.69°C and the cake sample is uncooked and its sensory properties are not acceptable. The cake that is safe and favorable with the sensory properties to the consumers was obtained by heat treatment for 30 minutes. After the cold point of a whole raw chicken was inoculated with 7.29 log-cfu/g S. Enteritidis, thermal treatment was applied at 220°C top-bottom fan cooking mode. The temperature at the cold point of 35 and 45 minutes heat-treated chickens reached 59.33 and 74.08°C, respectively, and 1.93 log-cfu/g and 5.33 log-cfu /g S. Enteritidis reduction caused in the samples respectively. S. Enteritidis cells were not detected in the whole chicken heat treated at 220°C for 60 minutes. The cakes, heat treated at 160°C top-bottom fan cooking mode for 30 minutes, were stored at two different storage temperatures as 4°C and 25°C for 72 hours.

Cypermethrin is a large spectrum action insecticide, globally employed to control pests in agriculture and some human and domestic animals ectoparasites. This study aimed to evaluate its toxicity and reproduction impairment in male guinea pig. Forty adult male guinea pigs were divided into 4 groups and orally submitted to 0, 92, 137.5 and 275 mg/kg body weight/day for 90 days. The weight of the liver increased significantly, while that of kidneys decreased significantly in treated animals compared to controls. Serum concentrations of creatinine, urea, ALAT, ASAT, total cholesterol, prostatic acid phosphatase increased significantly, while the testicular total protein level decreased significantly in groups given the insecticide relatively to the control. The testes weight, libido, serum level of testosterone, mobility, sperm count and the percentage of spermatozoa with entire plasma membrane decreased significantly in animals exposed to cypermethrin with reference to controls. The percentages of abnormal spermatozoa increased significantly in animals submitted to 137.5 or 275 mg/kg body weight (bw) of cypermethrin compared to control ones. On the testis histological sections of pesticide-treated animals, immature germinal cells were observed in the lumen of seminiferous tubules. Cypermethrin was toxic in male guinea pig and damaged reproductive parameters.
