CHANGES IN SOME PHYSICO-CHEMICAL CONTENT OF ANATOLIAN BUFFALO MILK ACCORDING TO THE SOME ENVIRONMENTAL FACTORS
(INT BUFFALO INFORMATION CTR, 2016) Sahin, A.; Yildirim, A.; Ulutas, Z.
The aim of this study was to determine the some physico-chemical content of raw milk from Anatolian water buffaloes raised under different village conditions in the Tokat province of Northern Turkey. The study materials included 1272 milk samples from 149 water buffaloes raised at 12 separate villages of the Erbaa, Turhal, and Pazar counties in the Tokat Province. Milk samples were collected during the morning milking between the months of February and May 2012 to 2014. The density, freezing point degree, dry matter, nonfat dry matter (or solid non fat), fat, protein, lactose, milk urea nitrogen and casein content of the milk samples were determined. The study results demonstrated that the mean dry matter, nonfat dry matter, fat, protein, lactose, casein content, density, milk urea nitrogen (MUN) and freezing point degree (FPD) of the raw milk samples were 16.99+/-0.108%, 10.88+/-0.036%, 5.98+/-0.107%, 4.85+/-0.043%, 5.17+/-0.021%, 3.61+/-0.036%, 1029+/-0.056, 21, 22 mg/dl and 0.55 degrees C, respectively. The study data were evaluated according to the water buffaloes' lactation stage, parity, and season by using the SPSS statistical program. It was concluded that the sampling time, parity, village conditions, stage of lactation and calving age had a significant effect (P<0.05) on the density, freezing point degree, dry matter, nonfat dry matter, fat, protein, lactose, and casein content of raw milk from the Anatolian water buffalo.

(Facta-Fundacio Arnco Ciencia Tecnologia Avicolas, 2017) Eleroglu, E.; Yildirim, A.; Duman, M.; Sekeroglu, A.
This study was conducted to compare edible giblets weight, tibial bone mineral density (BMD), and bone mineral content (BMC) of two slow-growing broiler genotypes (Hubbard S757; S757 and Hubbard Grey Barred JA; GB-JA) reared with outdoor access, and to determine the relationship between these variables. Day-old chicks (straight-run) of the genotypes S757 (n=120) and GB-JA (n=120) were housed for 98 days. Each genotype was assigned to six pens of 20 birds each. Birds were reared in indoor floor pens and moving shelters with outdoor access (during daylight hours). Absolute body (BW), heart (HW), spleen (SW), liver (LW), gizzard (GW), and abdominal fat pad (AFW) weights of the genotype S757 and male birds were statistically higher than that of the genotype GB-JA and female birds. Genotype statistically affected relative HW, whereas sex affected relative GW. Although BMD values were not influenced by genotype or sex, S757 birds and males presented statistically higher tibial BMC, lean, lean+ BMC, total mass values (g) and area (cm(2)) compared with GB-JA birds and females. BW, HW, SW, LW, GW and AFW were positively correlated with BMC obtained by DXA. In conclusion, the measured traits influenced by genetic strain and sex. The use of the Hubbard S757 genotype in organic production systems with outdoor access is recommend.

Effect of cage tier and age on performance, egg quality and stress parameters of laying hens
(SOUTH AFRICAN JOURNAL OF ANIMAL SCIENCES, 2014) Sekeroglu, A.; Duman, M.; Tahtali, Y.; Yildirim, A.; Eleroglu, H.
This study was conducted to investigate the effects of cage tier and age on performance characteristics of layer hybrids, egg quality and some stress parameters. Ninety laying hens (hybrid ATAK-S) of similar bodyweights were used in the experiment. They were housed in three-tier conventional battery cages (bottom, middle and top) with 600 cm(2)/per bird. The experiment was conducted on hens from the age of 18 weeks to 42 weeks. Layers at the age of 18 weeks were randomly allocated to conventional three-tier battery cages with five replicates of six hens per treatment in a completely randomized design. In the bottom, middle and top tiers, 5% age of yield was observed as 151, 146 and 156 days, respectively; 50% age of yield was 162.4, 158.6 and 161.8 days; 5% yield age bodyweight (BW) as 1597.8, 1460.5 and 1599.2 g; 50% yield age BW as 1708.7, 1666.4 and 1671.7 g, respectively. The effects of cage tiers on week 42 BW, feed conversion ratio (FCR), tonic immobility (TI), egg weight (EW), egg yield (EY), and most external and internal quality traits of the hens' eggs were found to be insignificant. Except for shape index (SI) and albumen pH, internal and external quality traits of eggs were significantly affected by age of the hens. In addition, there were significant effects of age on the FCR, EY, EW and oviposition time. The effects of cage tier on tonic immobility (TI) in week 42 and viability were found to be insignificant, but TI in week 30 was found to be significant. It can be concluded that cage tier did not have significant effects on egg yield, egg quality and indicators of stress parameters studied in the experiment. However, these parameters were affected by the age of the hens at the beginning of the laying period.
Effect of Eggshell Color on the Egg Characteristics and Hatchability of Guinea Fowl (Numida meleagris) Eggs
(FACTA-FUNDACIO ARNCO CIENCIA TECNOLOGIA AVICOLAS, 2016) Eleroglu, H.; Yildirim, A.; Duman, M.; Okur, N.
The objective of this study was to determine the effects of eggshell color of guinea fowl (Numida meleagris) eggs on eggshell quality and hatchery results. The highest mean grey value (MGV), integrated density (ID), lightness (L*) and Hue angle (H*) values were obtained in eggs with lighter eggshell color. The effects of color difference (Delta E*) value levels on egg characteristics were evaluated. Eggshell color presented different (p<0.01) MGV, ID, L*, redness (a*), yellowness (b*), H* and Chroma (C*) values. Eggs with lighter color presented thicker eggshells and lower egg weight loss on day 25 of incubation (p<0.05) compared with intermediate and darker eggs. Eggshell color did not have any significant effect on fertility and hatchability (p>0.05). In conclusion, under the conditions of the present study, eggshell color influenced eggshell thickness and weight loss, but not hatching parameters of guinea fowl eggs. Further studies on this subject should be carried out.
Effects of Korean ginseng (Panax ginseng C.A. Meyer) root extract on egg production performance and egg quality of laying hens
(SOUTH AFRICAN JOURNAL OF ANIMAL SCIENCES, 2013) Yildirim, A.; Sekeroglu, A.; Eleroglu, H.; Sen, M. I.; Duman, M.
This study was conducted to determine the effect of Korean ginseng (Panax ginseng C.A. Meyer) root extract (PGRE) on egg production and egg quality characteristics of hens at the beginning of their laying period (20 weeks old). Four groups of commercial hens (Atak-S; Turkish native hybrid) were fed with diets containing 0 mg, 50 mg, 100 mg and 150 mg PGRE/kg. Experimental results indicated that dietary PGRE had no effect on feed intake, feed efficiency, egg mass (EM) or egg production parameters. Over 12 weeks, hen-day egg production (HDP) of the groups was 73.5%, 74.8%, 69.2% and 79.0%, respectively. The effect of different levels of PGRE on egg weight, shape index (SI), specific gravity, shell thickness, Haugh Unit (HU), yolk index (YI) and albumen index (AI) was not statistically significant during the entire experiment. Egg yolk colour was conspicuously lower in the 100 mg and 150 mg PGRE/kg groups than in the control. The L*, a* and b*, hue (H) and chroma (C*) values for eggshell colour were not significantly different among the groups, except for the colour difference (Delta E*, (L-2+a(2)+b(2))(1/2)), where values in PGRE groups were higher than in the control group. The trolox equivalent antioxidant capacity (TEAC), ferric reducing antioxidant power (FRAP) and total phenolics concentration of PGRE were 598 +/- 1.841 mmol trolox/kg, 15.45 +/- 0.457 mmol TEAC/kg and 1.02 +/- 0.03 g gallic acid equivalents (GAE)/kg, respectively. Serum glucose, cholesterol and triglyceride concentration were similar in the PGRE supplemented groups and the control. In conclusion, the dietary supplementation with PGRE did not affect the productivity performance traits and egg quality of hens at the beginning of the laying period.
Microbiological quality of pastrami and associated surfaces at the point of sale in Kayseri, Turkey
(W B SAUNDERS CO LTD, 2017) Yildirim, Y.; Onmaz, N. Ertas; Gonulalan, Z.; Al, S.; Yildirim, A.; Karadal, F.; Pamuk, S.
Objective: The aim of this study is to trace the possible relations between the hygienic status of slicing utensils and the microbiological quality of pastrami. Study Design: A total of 75 pastrami retail markets were visited in Kayseri, Turkey, where the pastrami (a ready-to-eat meat product) is commonly produced and consumed. Sliced pastrami, the cutting board and knife surface swabs were collected from each pastrami retail point to trace possible sources of contamination. Methods: Samples were analysed for the presence of total viable counts (TVC), total coliforms, Escherichia coli, members of Enterobacteriaceae, Staphylococcus aureus and Listeria spp. In addition, pastrami samples were analysed for sulphite-reducing Clostridium spp. and Toxoplasma gondii. Results: When compared with the target values of related literatures, a total of 6 (8%) pastrami samples were found unsatisfactory as a result of TVC (5.3%), Enterobacteriaceae (5.3%), E. coli (2.6%), S. aureus (2.6%), Listeria spp. (2.6%) and Listeria monocytogenes (1.3%) contaminations. No T. gondii positivity was observed among the pastrami samples. None of the cutting board and knife surface swabs were found to harbour TVC level >10(3) cfu/cm(2), E. coli and L. monocytogenes. For the total coliforms, 7 (9.3%) and 5 (6.6%) of cutting board and knife surface swabs were found to exceed the target value (<2.5 cfu/cm(2)), respectively. No statistically significant correlation was detected between the organisms on pastrami and slicing utensils indicating that pastrami were not cross-contaminated by the contact surfaces. Conclusion: More emphasis needs to be placed for training of food handlers and to apply good hygienic practices at the point of pastrami sale. The conditions at retail points must be monitored and inspections should be tightened to protect public health. (C) 2017 The Royal Society for Public Health. Published by Elsevier Ltd.

Relation between egg shape index and egg quality characteristics
(EUGEN ULMER GMBH CO, 2016) Duman, M.; Sekeroglu, A.; Yildirim, A.; Eleroglu, H.; Camci, O.
The objective of this study was to investigate the impact of the egg shape index on egg quality characteristics. The eggs used in this study were laid by layers of the ATAK-S strain. The eggs were classified with respect to shape index (SI), namely sharp eggs (SI < 72), normal (standard) eggs (SI = 72-76) and round eggs (SI > 76). A total of 166 eggs were analysed to determine egg quality characteristics. Effects of egg shape on L*, a*, b*, specific gravity, albumen index and Haugh unit were statistically significant. However, the effects of egg shape index on egg weight,.E value, breaking strength, shell thickness, shell weight, surface area, yolk index, yolk colour, albumen pH and albumen and yolk blood spots were not significant. Statistically significant correlations between egg shape index and egg weight, L*, b*, specific gravity, egg surface area, albumen index and Haugh unit were determined. But, shape index did not correlate with a*, Delta E value, breaking strength, shell thickness, shell weight, yolk index, yolk colour and albumen pH. In conclusion, it is clear that the shape index has an effect on some egg quality characteristics. Therefore, shape index should be considered for use in future breeding programs.
