2016
Bakheit S.A. | Faye B. | Ahmed A.I. | Musa Elshafei I.
Eighteen (18) lactating she-camels and two mature male for mating were used to determine the effect of Management System on camel calving interval, The camels were maintained under semi-intensive (N = 9) and Traditional management system (N = 9) in North Kordofan State, western Sudan. The experimental females in each group kept together with the bull during 18 months. Blood samples were collected from jugular vein since 4-months post-partum and continue 14 successive months at monthly interval. The serum samples were separated and stored at -20°C and were analysed for progesterone concentration using progesterone specific radio immuno assay (RIA) kits. The results indicated that under semi-intensive system 77.8% of females had been pregnant in 5th - 8th month post-partum and the calving interval varying between 17 to 20 months. Under traditional system and during the experimental period 44.5% of females were pregnant in the 11th – 16th month and the calving interval varying between 23 to 28 months. The ratios of pregnant vs non-pregnant during experimental period in semi-intensive and traditional were 88.9% vs 11.1% and 44.5% vs 55.5%, respectively. Beside the behavioural signs progesterone level consider a good indicator for pregnancy in camels. In pregnant females Progesterone concentration increased significantly during early months. The range of Progesterone concentration varied between 1.10 – 5.76 ng/ml and 0.67 – 2.53 ng/ml in semi-intensive and traditional system, respectively. Our results allow quantifying this impact. With a supplemented diet including 2 Kg of concentrates and 5 kg of roughages per day, the fertility rate will be improved of 67%. It would be possible to expect more than two fold young camels in a year by supplemented 5 kg of concentrates. We conclude that under semi-intensive management dietary supplement during post-partum and early lactation period improves reproductive parameters for instance shortened calving interval.

Mostrar más [+] Menos [-]Effect of Modified Atmosphere Packaging on the Refrigerated Storage of Mantı
2016
Sinan Uzunlu | Işıl Var
Mantı, the traditional Turkish food, was subjected to modified atmosphere packaging (MAP) compositions of MAP 1 (80% CO2 + 20% N2), MAP 2 (40% CO2 + 60% N2), MAP 3 (60% CO2 + 40% N2) and control (packaged under atmospheric composition) to extend its refrigerated storage at 4°C. The physical, chemical and sensorial qualities of each package were assessed by analysing headspace gas composition, pH, water activity, 2-thiobarbituric acid (TBA), dry matter, lipid content and a sensory analysis of both cooked and raw mantı samples. The compositions of MAP samples (MAP 1, MAP 2 and MAP 3) resulted in the maximum storage time of 126 days versus 20 days in normal atmospheric packaging (control). In conclusion, 60% CO2 or either 80% CO2 with N2, as a make-up gas, should be implemented in the mantı process.

Bukola Christianah Adebayo-tayo | Soore Daniel Ademuwagun | Solomon Omoniyi Alao
Non-dairy probiotic functional foods are receiving considerable interest recently owing to the inability to cause allergy in certain segments of the population. Studies on probiotication were carried out to determine the suitability of kunun-zaki as food matrix for production of probiotic beverage using single and mixed culture of Pediococcus acidilactici KU7, Pediococcus pentosaceus CREC5 and Lactobacillus rhamnosus GG. Probioticated and un-probioticated kunun-zaki samples were designated PKZ and UPKZ, respectively. There was a significant difference in the viable count during storage. Viable counts of the LAB strains decreased with increasing storage time with P. acidilactici KU7 having the highest viability at the beginning and end of storage (3.43 ± 0.06 and 0.93± 0.12 x108 cfu/ml). There was a decrease in pH of the PKZ samples within the 1st and 3rd week with corresponding increase in lactic acid production (71.16 ± 0.01 – 441.39 ± 0.01). Marked increase in pH and a decline in lactic acid were observed at the 4th week of storage in all samples. Total soluble solids content of the beverage was observed to decrease with increasing storage time ranging from 8.25 ± 0.01-4.97± 0.01. There was no significant difference in pH and total soluble solids of UPKZ and colour of the PKZ and UPKZ samples during storage. All the PKZ samples were able to inhibit the growth of selected pathogens with marked variability amongst the samples. The UPKZ sample also showed slight inhibitory activity. The samples showed a decline in proximate and mineral composition at the end of storage. Sensory evaluation showed the PKZ samples were preferred over the UPKZ samples. This study shows that probioticated kunun-zaki can serve as a suitable non-dairy alternative to dairy probiotic formulations and would be of health benefits to potential consumers.

2016
Serkan Yeşil | Kubilay Kurtuluş Baştaş
Charcoal rot is a soil and seed borne, economically important fungal disease on dry bean in Turkey. Twenty bean isolates of M. phaseolina collected from different locations in Turkey during 2008 and 2012 years were studied for genetic variability using random amplified polymorphic DNA (RAPD) assay, chlorate sensitivity on medium supplemented with 120mM of potassium, phenotype of colony, and pathogenicity. Isolates were identified as M. phaseolina based on morhological features and PCR assays using species-specific primers (MPKF1and MPKR1). Isolates of M. phaseolina were analysed for their aggressiveness on the susceptible bean cv. Akman 98, by soil inoculation method. Isolates exhibiting a dense chlorate phenotype were chlorate-resistant, while those possessing feathery and restricted chlorate phenotypes were chlorate-sensitive. More than half of the isolates (55%) were resistant to chlorate and produced dense phenotype, while 35% isolates showed feathery and two isolates (10%) showed restricted growth. DNA from 20 isolates was subjected to genetic diversity analysis by the RAPD method using 14 randomly chosen 10-base random primers, and low genetic diversity (33.3%) was observed among the tested isolates.

Uwemedimo Emmanuel Udo | Akaninyene Uwemedimo Udo
The leaves of Cnidoscolus aurifolia were analysed for their chemical, antinutrients, proximate and mineral element compositions using standard procedures. Phytochemical screening revealed the presence of alkaloids, saponins, flavonoids, terpenes and tannins while anthraquinones, glycosides and phlobatannins were absent. Proximate analysis indicated high protein content (59.45 ± 0.07%) with crude fibre and fat also present in appreciable quantities. Mineral elements determination showed the presence of calcium, iron, magnesium, potassium and zinc. Antinutrient analysis of the leaf extract of C. aurifolia indicated low levels of phytic acid and hydrocyanide well below the lethal doses. An unusually high oxalate level of 404.80 ± 0.11 mg/100 g (dry weight) was also obtained although still below toxic level. These results support the ethnomedicinal and nutritional uses of this plant and suggest that the consumption of leaves of C. aurifolia is not harmful nutritively.

Antioxidants are naturally occurring substances that combat oxidative damage in biological entities. An antioxidant achieves this by slowing or preventing the oxidation process that can damage cells in the body. It does this by getting oxidized itself in place of the cells. The aim of the present study was to evaluate the in vitro antioxidant and free radical scavenging activities of aqueous and 95% methanol leaf extracts of four herbs viz. Trigonella foenum-graecum L, Murraya koenigii, Coriandrum sativum and Centella asiatica which have frequent use in Indian cuisine. Both aqueous and 95% methanol leaf extracts have shown significant amount reducing power. Both aqueous and 95% methanol leaf extracts of Coriandrum sativum had significant DPPH radical scavenging activity with IC50 value of 0.21± 0.3 mg/L and 0.176 ± 0.008 mg/L respectively. The aqueous leaf extract of Trigonella foenum-graecum L showed low scavenging activity. Among all the leaf extracts, the aqueous leaf extract of Centella asiatica has exhibited significantly high NO radical scavenging activity (80%) with IC50 value of 0.11 ± 0.17 mg/L. The aqueous leaf extracts of the samples have showed significantly high superoxide radical scavenging activity. The activity was maximum for the aqueous leaf extract of Centella asiatica, IC50 value is 4.36 ± 0.41 mg/L. anti lipid peroxide activities were very high ( 90 %) for aqueous leaf extracts of Coriandrum sativum (IC50 = 0.064 ± 0.85 mg/L) and Centella asiatica (IC50 = 0.066 ± 0.9mg/L) at a concentration of 0.16 mg/L. The aqueous leaf extracts of the samples were found to contain large amounts of flavonoids and phenolic compounds and exhibited high antioxidant and free radical scavenging activities. These in vitro assays indicate that these plant extracts are significant source of natural antioxidants which might be helpful in preventing the progress of various oxidative stresses.
