Sezai Alkan | Taki Karslı | İsmail Durmuş | Kemal Karabağ
The aim of this study was to investigated the effects of the egg shape index on egg quality characteristics in Guinea fowl. For this, the eggs were classified in terms of egg shape index, as ≤ 75, < 76 -77 > and ≥ 78. A total of 100 Guinea fowl eggs were evaluated to determine the egg quality traits ( egg weight, eggshell thickness, eggshell surface area, eggshell weight per unit surface area, eggshell ratio, albumen index, albumen ratio, yolk index, yolk ratio, yolk/albumen ratio, haugh unit and egg volume). In this study, eggshell thickness, eggshell weight per unit surface area, eggshell ratio, albumen index, albumen ratio, yolk index, yolk ratio, yolk/albumen ratio and haugh unit were not significantly affected by egg shape index groups. Whereas egg weight, eggshell surface area and egg volume were significantly affected by egg shape index groups. At the same time, there were found significant relationship between the egg shape index and egg quality traits. Egg shape index was found to be an important factor affecting the egg quality characteristics.

Salmonella is considered as a global problem ranking first among food borne diseases. All motile Salmonella of poultry origin are zoonotic and readily transmit to human via meat and eggs but reports on non - typhoidal Salmonella serovars circulating in layer chickens is very limited in South-East Asian countries including Bangladesh. Salmonella serovars isolated from apparently healthy chickens were characterized in the present study. Of 170 samples (cloacal swab 150 and feed 20) collected from commercial layer farms, motile Salmonella was isolated 4% (6/150) and 50% (10/20) respectively by cultural, biochemical, motility test and by detection of hisJ gene. About 5% (8/170) samples possessed serovar-specific gene fimA, suggesting that isolates were Salmonella enterica serovar Typhimurium. Antimicrobial susceptibility testing demonstrated that the isolated serovars were multidrug resistant. Therefore apparently healthy layer chickens harbour and transmit S. Typhimurium to the environment, although little is alarming since it has zoonotic significance and the isolates were resistant to commonly used first line of antibiotic in Salmonella infection.

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.

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.

Tugay Ayasan | Mikail Baylan
The increasing costs of conventional feedstuffs like corn, soybean meal and fish meal for poultry diets is pushing the need to find less expensive alternatives. Mulberry grows well in the tropics and subtropics, and is reported to have excellent nutritional value. Mulberry leaves are very rich in protein (15-35%), minerals (2.42-4.71% Ca, 0.23-0.97% P), 1130-2240 kcal/kg metabolic energy (ME). The amino acids composition of mulberry leaf meal indicates it is a good source of essential amino acids especially lysine (1.80%) and leucine (2.58%). In this paper, studies made on the mulberry leaf used in nutrition of poultries have been reviewed.

Mehmet Koç | Figen Kaymak-Ertekin
Spray drying is the most preferred drying method to produce powdered food in the food industry and it is also widely used to convert sugar-rich liquid foods to a powder form. During and/or after spray drying process of sugar-rich products, undesirable situation was appeared such as stickiness, high moisture affinity (hygroscopicity) and low solubility due to low molecular weight monosaccharides that found naturally in the structure. The basis of these problems was formed by low glass transition temperature of sugar-rich products. This review gives information about the difficulties in drying of sugar-rich products via spray dryer, actions need to be taken against these difficulties and drying of sugar-rich honey and fruit juices with spray drying method.

The aim of this research was to examine the larvicidal activity of essential oil (EO) extracted from nutmeg (Myristica fragrans Houtt) leaves and fruits by steam distillation, and to analyze its chemical compounds. The EO yield of nutmeg leaves and fruits collected from the same tree was 0.66% and 0.30%, respectively. Larvicidal tests with the EO were carried out against Aedes aegypti (L.) (Diptera: Culicidae). The concentrations of nutmeg EO used for the larvicidal assay were 50, 100, 150, 200, and 250 μg/mL. The results showed that fruit oil was more toxic than the leaf oil. LC50 values of leaf and fruit EOs were 133.8 and 110.1 µg/mL, respectively. The chromatogram of GC-MS showed that the chemical components in nutmeg leaf and fruit EOs were dominated by α-pinene, sabinene, β-pinene, delta-3-carene, limonene, β-phellandrene, α-terpinolene, linalool, safrole, croweacin, and myristicin.

Ilahy Riadh | Siddiqui Mohammed Wasim | Tlili Imen | Piro Gabriela | Lenucci Marcello Salvatore | Hdider Chafik
This study investigates the antioxidant components (total carotenoids, lycopene, β-carotene, total phenols, flavonoids, ascorbic acid and total vitamin C) as well as the hydrophilic and lipophilic antioxidant activities (HAA and LAA) of tomato genotypes consisting of one ordinary cultivar Rio Grande and the two high-lycopene breeding lines HLT-F71 and HLT-F72. The correlation of nutritional value to L∗, a∗, b∗ colour indexes and a∗/b∗ ratio was also investigated in whole and fresh cut tomato fruits. Except for β-carotene content, significant differences were found among cultivars for antioxidants. The berries of both HLT-lines recorded higher antioxidant contents, HAA and LAA (TEAC and FRAP assays) than Rio Grande. Under controlled conditions, HLT-F72 reached the highest levels of total carotenoids (165.5 mg β-ca Eq per kg fw), lycopene (150.1 mg per kg fw) and total phenolics (549.7 mg GAE per kg fw). However, HLT-F72 exhibited the highest levels of ascorbic acid (193.3 mg per kg fw), total vitamin C (271.6 mg per kg fw) and flavonoids (450.5 mg RE per kg fw). Line HLT-F71 showed the highest HAA (148.0 µM Trolox per 100 g fw and 4.2 mM FRAP per g fw) and LAA values (258.5 µM Trolox per 100 g fw and 3.2 mM FRAP per g fw respectively). Colour readings in red ripe fresh cut tomato berries particularly a∗, b∗ and the ratio a∗/b∗ could represent an indicator not only for lycopene but also for other phytochemicals and resulting antioxidant activities. HLT-Lines may serve as a starting point for the development of semi-determinate growth habit tomato cultivars with higher functional quality.
