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.

The study presents first report of Agrobacterium mediated genetic transformation in Rice paddy herb (Linmophila aromatica). A. tumefaciens strain C58C1 harboring pBin19 Plasmid containing β-glucuronidase (GUS) and neomycin phosphotransferase II (nptII) gene, under the control of 35S promoter and NOS terminator was used. Shoot tip explants were inoculated for 30 min followed by co-cultivation for 72 h and selected on agar semi solidified MS medium containing 100 mg/l Kanamycin and 1.0 mg/l BA; whereas total number of 78 putative transgenic shoots were obtained. The shoots were rooted on MS medium containing 1.0 mg/l IBA and 100 mg/l Kanamycin where 43 plants survived and rooted. Expression of GUS gene in the putative transgenics was confirmed by histochemical GUS assay. Visible localised gus expression was noted in a few cells and callus tissues of 4 plantlets that were photographed using compound light microscope.

The present study was conducted to find out an in vitro efficient method for multiple shoot regeneration of two local chickpea varieties. The mature embryos were excised of two chickpea varieties i.e. Bittle-98 and Dasht-2000 (with cotyledon and without cotyledon) used as explants. The explants were cultured on Murashige and Skoog (MS) medium supplemented with three concentrations of (2, 3, 4 mg/l) 6-benzylaminopurine (BAP) using explant with and without cotyledon. Further, 0.5 mg/l α-naphthaleneacetic acid (NAA) along with varied concentrations of BAP (2, 3, 4 mg/ l) was also tested using explant with cotyledon. 3 mg/l BAP alone and 3 mg/l BAP with 0.5 mg/l NAA were found the most effective cytokinin in multiple shoot induction in both tested varieties. Bittle-98 and Dasht-2000 showed 82% and 76% elongation in shoots induction with 0.2 mg/l Indole-3-acetic acid (IAA). Root formation was recorded 80% and 60% in Bittle-98 and Dasht-2000 with 1.0 mg/l Indole-3-butyric acid (IBA). Whereas, recorded root formation was 40 and 20% in Bittle-98 and Dasht-2000 with 1.0 mg/l NAA. The best response for rooting observed in Bittle-98 as its roots were thick, long and strong. Plantlets of Bittle-98 were acclimatized in solid medium for 7-14 days. The successful invitro regeneration of Bittle-98 was observed, when excised embryo with cotyledon were used as explant, made it valuable for genetic transformation.

2016
Sherine Fathy Mansour | Dalia Elsaid Abozaid
This study examines the impact of New Integrated Management Package (IMP) adoption on income and poverty among fodder farming household in Sahl El-Tina. The IMP such as Rate, time, and methods of nitrogen fertilization and other fertilization, Leaching requirements for some crops, Intercropping system, Use of suitable crop genotype/variety, Use of modern irrigation systems or modified systems to save water, date, rate and method of planting. The study aims mainly to improve the lives of small farmers through the level of dissemination and application of cultivation techniques forage crops tolerant to salinity through develop and disseminate technologies packages of forage production. And reducing their probability of falling below the poverty line. Therefore suggest that intensification of the investment on IMP dissemination is a reasonable policy instrument to raise incomes and reduce poverty among fodder farming household. It used instrumental variables (IV)-based estimator to estimate the Local Average Treatment Effect (LATE) of adoption of IMP on income and poverty reduction, using cross-sectional data of 200 farmers from Shal El-Tina. The findings reveal a robust positive and significant impact of IMP adoption on farm household income and welfare measured by per capita expenditure and poverty reduction. Specifically, the empirical results suggest that adoption of IMP raises household per capita expenditure and income by an average of 529.27$ and 1371$ in Shal El-Tina per cropping season respectively, thereby reducing their probability of falling below the poverty line. Therefore suggest that intensification of the investment on IMP dissemination is a reasonable policy instrument to raise incomes and reduce poverty among fodder farming household, although complementary measures are also needed. The incidence of poverty was higher among non-IMP adopters (55.2%) than IMP adopters (49.5%). In addition, both the depth and severity of poverty were also higher (20.85% and 15.42%) among non-adopters than the adopters (18.48% and 9.88%). All three poverty measures indicate that poverty was more prevalent and severe among non-adopters compared to adopters.

Before serving the meals, the managements that operate in the production and distribution of table d’hôte meals, the data related to whether it's appropriate for the food hygiene regulation and the other legal requirements are so insufficient. So, an interview study was performed for the present conditions of the manufactures producing and serving meals and the good hygiene practices profile of their working personal in the plants with regard to Law No.5966 on Veterinary Services, Plant health, Food and Feed in the Samsun city. The survey was applied in catering enterprises and face to face interviews with a total of 258 people (employees and managers responsible for the kitchen area) and at the same time observing the operating conditions of 32 companies in 9 different counties. The questions of survey included gender, age, education level, professional experience of workers, real production capacities, the power of engine, number of employees in production, and findings related to good hygiene practice. It was observed that the design and layout of the production area in terms of good hygiene practices were not sufficient in some manufactures and only four manufactures had positive air pressure ventilation. It was stated that tools and equipment were required to take more precautions against the risk of corrosion. It was established that cleaning and disinfection process, personal hygiene rules and dissolving operations for frozen food were inadequate. It was determined that record forms were not sufficient to provide the traceability. Hazard and risk factors will be controlled by establishment of practical food safety management system in catering sector.

Toll-like receptors (TLRs) play an important role in non-specific immunity against different infectious agents such as bacterium or parasite. The aim of this work was to investigate the allele and genotype frequencies of three single-nucleotide polymorphisms (SNPs) in bovine TLR1 gene in native Turkish cattle breeds. DNA samples were extracted using the phenol chloroform protocol from 77 Zavot, 60 Turkish Grey, 51 East Anatolian Red, 69 Anatolian Black and 46 South Anatolian Red cattle. Target regions of the TLR1 gene were digested BsII and HpyI88III restriction enzymes. Results showed that the (A) allele frequency had higher in all native Turkish cattle breeds of the TLR1-G1409A locus. The (F) allele frequency was found to be higher compared to (E) allele in the TLR1-G1550A site. The frequencies of both (C) and (T) alleles were close to each other in the TLR1-C632T site. In conclusion genetic polymorphisms exist in Turkish native cattle populations in terms of known TLR1 variants.

The maize germplasm variation is valuable for breeders to develop elite hybrids with increased mineral contents in the maize grain to eliminate mineral malnutrition, which is referred as HIDEN HUNGER. Therefore, we aimed to determine mineral element diversity of maize landraces collected from different geographical regions of Turkey. There was huge diversity for all mineral traits and other quality traits. Turkish maize landraces showed high variation for Zn (17-41.34 mg kg-1), Fe (13.52-29.63 mg kg-1), Cu (0.77-3.34 mg kg-1), Mn (5.68-14.78 mg kg-1), Protein (6.6-11.6%), starch content (73.3-80.0%), oil content (3.15-4.7%) and thousand grain weight (177.0-374.9g). There were significant positive and negative associations among mineral elements and quality traits. The principal component analysis differentiated some maize landraces from the rest, and these diverse landraces could be used in the maize breeding program with biofortification purpose.
