Body Weight and Some Morphological Characteristics of Kangal Dogs
(Medwell online, 2007) Daskiran, Irfan
In this study, some descriptive morphological characteristics of Kangal shepherd dogs were assessed. Body weight and some body measurements were investigated in 38 Kangal shepherd dogs at different ages. In female and male dogs, the average live weight was 34.2 and 43.4 kg; height at wither was 65.2 and 71.7 cm; ramp height was 64.5 and 72.1 cm; body length was 66.2 and 7 1.1 cm; body circumference was 78. 8 and 86.1 cm; leg length was 39.4 and 41.9 cm; face length was 10. 8 and 11.2 cm; head length was 23.8 and 24.8 cm; face width was 13.1 and 14.8 cm, respectively. It is true that the large scaled field studies should be carried out to determine the all breed characteristics of Kangal shepherd dogs.

(Springer, 2010) Daskiran, Irfan; Bingol, Mehmet; Karaca, Serhat; Yilmaz, Ayhan; Cetin, Ayse Ozge; Kor, Askin
The study was conducted to determine the effect of feeding systems on fattening performance, slaughter, and carcass characteristics of male Norduz kids. In the study, 20 male Norduz kids weaned at 2.5 months of age were divided into two groups after weaning. The first group was reared under semi-intensive conditions (SI) on a mixture of pasture and concentrate, and the second group was reared under extensive conditions (E) on pasture only. SI group had higher final weight (35.30 kg versus 32.81 kg), daily weight gain (153.10 g versus 132.14 g), and warm carcass yield (44.84% versus 46.55%) compared to the E group although there were no significant differences. Body organs, carcass parts, prime cuts, and chemical composition of the chop area did not also differ in two groups significantly. As a conclusion, this study showed that semi-intensive feeding systems improved kid fattening performance and carcass characteristics.
Factor Analysis Scores in a Multiple Linear Regression Model. for the Prediction of Carcass Weight in Akkeci Kids
(Garuda Scientific Publications, 2007) Keskin, Siddik; Daskiran, Irfan; Kor, Askin
In this study, the relationships between carcass weight and 10 body measurements (Slaughter weight, withers height, body length, chest depth, chest width, chest circumference, leg circumference, leg width, leg length and rump width) were examined through factor and multiple linear regression analyses. It was observed that three factors e.g. Form, Circumference and Wideness had significant effects on carcass weight and these factors together accounted for 83.9% of variation in carcass weight.
Factors Affecting Lactation Milk Yield and Lactation Curve of Norduz Sheep in Farmer Condition
(Kafkas Univ, veteriner Fakultesi dergisi, 2012) Koncagul, Seyrani; Daskiran, Irfan; Bingol, Mehmet
In this research, mathematical models describing lactation curve of Norduz sheep breed were compared, and lactation parameters were estimated by selected model describing the lactation curve better than others. Then, factors affecting the lactation parameters and lactation milk yield were investigated. In the analysis, a total of 2.366 test-day records belonging to 189 completed lactations were used. It was observed that the lactation curve showed a decrease after lambing followed by an increase towards to the middle of the lactation, and then a decrease afterwards, like a sinusoidal shape. The forth degree Legendre polynomial model (LEG4), comparing to other models used, showed the best performance in describing the lactation curve of Norduz sheep raised in farmer condition. Total lactation milk yield, corrected to 180-day lactation lenght, was 130.9 +/- 3.24 kg. It was found that parity, lambing age and lambing month have a significant effect on lactation milk yield (LSV), and lambing month and parity also have a significant effect on lactation trajectory.

(Elsevier Science Bv, 2018) Daskiran, Irfan; Savas, Turker; Koyuncu, Mehmet; Koluman, Nazan; Keskin, Mahmut; Esenbuga, Nurinisa; Bingol, Mehmet
Goats play an important socio-economic role in many marginal rural areas of the world. Indigenous goat breeds have taken an important role in the livelihood strategies of impoverished farmers, especially those in harsh, remote areas. Those roles include their use as security and diversification of assets, social and cultural functions. They are also valued for their productive performance, adaptation and disease resistance. Turkey is one of the leading countries in the world for goat population and production. Hair, Kilis, Angora and Shami are the main goat breeds of the country. Hair goats are raised in many parts of the country but are concentrated particularly in the mountainous regions country, while the Angora breed is concentrated mainly in Central Anatolia. Kilis and Shami goats are known for their higher milk yield and litter size and are mainly focused in the south-east region of Turkey. Apart from these four breeds, the minor breeds such as Honamli are located in the Bolkar Mountains in the Mediterranean region (specifically Antalya, Isparta and Konya) and the Norduz breed in Van province. A limited number of dairy goats such as Mainz, Saanen and their crossbreds are located in the Aegean and Marmara regions of Turkey. The population of goats in Turkey is about 11 million head. Hair goats make up approximately 10 million of the total number and the rest make up the balance. There are many reasons for goat production in Turkey, including the country's geography and ecological condition, as well as the socio-economic situation of the rural communities. Goats have been raised in the Anatolian Plateau for many centuries providing dairy, meat, hide and hair to the inhabitants. It is the main source of animal protein for the rural masses in the mountainous regions of the country and less so for the urban population. Goats provide approximately 3% of the total red meat, 2.5% of the total milk and 18.5% of the total hide production for Turkey. They are also the only source of mohair and animal hair production in the country. Although their number and economic significance has decreased over the years, goat breeding still plays and important socio-economic role for the people living in remote areas of Turkey. Investments in intensive goat enterprises have increased significantly in the last few decades in Turkey although marketing margins across the value chain between producers, middlemen, processors, and consumers unjustifiably irregular.
Growth Characteristics of Indigenous Norduz Female and Male Lambs
(Ankara Univ, Fac Agr, 2010) Daskiran, Irfan; Koncagul, Seyrani; Bingol, Mehmet
The objectives of the present study were to compare the growth curve models for their ability to describe the growth of Turkish Norduz sheep, and to estimate the growth curve parameters by the selected growth model. The data were collected from 93 male lambs and 86 female lambs from birth to 198 day of age. Five different nonlinear models, Brody, Gompertz, Logistic, Bertalanffy and Negative exponential, were compared using coefficient of determination (R-2), asymptotic mature weight (BWA), residual standard deviation (RSD) and coefficient of correlation (r) between the observed and estimated growth curves. The Logistic growth model was observed to be appropriate for explaining the growth of Norduz female and male lambs. Male lambs grew faster and attained larger mature weight than female lambs showing that sex is the main factor affecting the growth of Norduz lambs. Type of birth had no effect on the growth of the lambs.
Inhibin Immunization in Norduz Sheep
(Archiv Fur Tierzucht, 2012) Bingol, Mehmet; Daskiran, Irfan; Cedden, Fatin; Demir, A. Ozge; Yilmaz, Ayhan
The objective of this study was to investigate the possibility of increasing ovulation rate in Norduz sheep by immunization against inhibin-based peptide immunogens. A total of 18 primiparious Norduz ewes were used for this experiment. Eight ewes have received two times inhibin a-subunit 1-32 porcine vaccine with 3 weeks interval. The rest was kept as control. Antibody binding test by standard ELISA method did not provide reliable information. However, ultrasonographic inspection showed that significantly high number of follicle with 5 mm and larger diameter (P<0.01) has developed in immunized ewes. Moreover, 3 of immunized ewes have lambed twin. However, twin birth was not observed in control group.
