Comparison of Growth Models in Norduz Female Kids
(indian veterinary Journal, 2007) Keskin, S.; Daskiran, I.
Growth is one of the important characteristics in livestock. Genetic and environmental factors have important effect on growth. Growth rate is not same in the life period of animals. Determinations of various growth parameters,such as body weight, body length and heart depth at different ages are quite important for selection-of animals at early phases of growth. Manipulation of selection due to these parameters helps to determine suitable management and feeding regimens and to decide optimal age at which animals can be used for production purposes (Bayram et al., 2004; Kor et al., 2006). Some authors (Lawrence and Fowler, 2002; Landgraft et al., 2002) informed that growth curve parameters can be also used as direct breeding criteria in improving some of the growths associated traits in addition to describing growth in animals. The aim of this study was to estimate the growth function of Norduz goats at early phases for regulation of the growth intensity, attaining adequate growth and development by feeding regimes and solving some herd management problems.
A Description of Growth Performances of Norduz Kids and Milk Yield of Norduz Goat
(National Centre for Agrarian Sciences, 2014) Bingol, M.; Daskiran, I.; Yilmaz, A.
In this research, growth performance of Norduz kids and milk yield of Norduz goats, a native gene resource in Turkey, were defined. The animals studied were brought from natural habitats to the animal research farm of Agricultural Faculty, Yuzuncu Yil University. Descriptive statistics for average birth, weaning, 30 th day, 60 th day, 90 th day, 120 th day, 150 th day and 180 th day weights of Norduz kids were found to be 2.98±0.07, 13.37± 0.44, 6.70±0.20, 10.88±0.34, 14.44±0.44, 17.92±0.48, 21.15±0.55, and 23.09±0.65 kg respectively. Least squares means of single kids and twin kids of Norduz were found to be 3.12±0.06 and 2.57±0.07 kg respectively. Least squares means of single male, single female, twin male and twin female kids of Norduz were found to be 3.23±0.08, 3.01±0.09, 2.81±0.09 and 2.33±0.10 kg respectively. Least squares means of lactation length and lactation milk yield were 226.4±7.23 day and 347.2 ± 40.06 kg respectively. Descriptive statistics of the growth of all kids revealed that in the time interval from birth to day 90 of age, birth to day 180 of age, birth to weaning (84 day) and weaning to day 180 of age daily weight gain were 0.193± 0.005, 0.145±0.004, 0.129±0.005 and 0.323± 0.043 kg, respectively. © 2014, National Centre for Agrarian Sciences.

Slaughter and Carcass Characteristics of Norduz Male Kids Raised in Either Intensive or Pasture Conditions
(2006) Daskiran, I.; Kor, A.; Bingol, M.
The aim of this study was to determine of the slaughter and carcass characteristics of Norduz male kids raised in either intensive or pasture conditions. Hot and chilled carcass dressing percentages in intensive and pasture groups were appeared to be 42.94±0.484% and 41.49±0.503%; 46.26±1.050% and 44.63±1.03%, respectively. In intensive and pasture groups, the omental fat and heart-lungs-liver proportions at slaughter weight of kids were determined as 1.18±0.209%, 0.29±0.065%; 4.75±0.107%, 4.08±0.134%, respectively. The kidney-knob and pelvic fat proportions at left half carcass weight were determined as 2.05±0.196% for kids raised in intensive conditions and 1.06±0.182% for kids raised in pasture conditions. In the rack joints, the lean portions of the intensive group and pasture group kids were 46.42±0.892% 50.50±1.990%, respectively. Total fat portions which contain subcutaneous fat and intermuscular fat were determined as 10.05±1.020% in intensive group and 4.16±0.477% in pasture group. In this study, it was concluded that; pasture group kids had similar slaughter and carcass characteristic values as intensively raised ones due to the special environmental condition and rich flora of the mentioned Norduz region of Van province. © Asian Network for Scientific Information, 2006.
Some Physical Characteristics of Coarse Fibre Obtained From Norduz Goat
(Medwell online, 2008) Daskiran, I.; Cedden, F.; Bingol, M.; Apkin, Y.
The aim of this study is to investigate some physical characteristics of coarse fibre in Norduz goat which is a local breed of Eastern Anatolia in Turkey. Fibres are sampled from shoulder, thigh and back of 48 female Norduz goat between 14 years-old. Fibre length and diameters do not vary significantly according to age and part of body. Fibres obtained from 3 years-old goats are thickest (74.4 +/- 6.20 mu m) while these from goats one year-old were found thinnest as 53.7 +/- 2.93 (p<0.05) mu m. Breaking strength value is found higher in 3 years-old goats when comparing with I year-old goats (18.7 +/- 0.38 vs 17.2 +/- 0.27) (p<0.05). Fibre diameter and length is negatively correlated (477) (p<0.05) in 3 years-old goats. The diameter and the breaking strength of fibres sampled from back are highly correlated (0.94) (p<0.01) in 4 years-old goats. In addition, elongation rate is positively correlated with breaking strength (0.88) and diameter (0.95) for fibres sampled from back of 4 years-old goats (p<0.01).
Usability of the Factor Analysis Scores in Multiple Linear Regression Analyses for the Prediction of Daily Milk Yield in Norduz Goats
(Tarbiat Modares Univ, 2017) Daskiran, I.; Keskin, S.; Bingol, M.
The aim of this study was to determine the relationship between daily milk yield and udder traits using multiple regression analyses in order to predict daily milk yield in Norduz goats. 10 udder traits including upper udder height, bottom udder height, udder depth, udder width, udder circumference, left teat length, right teat length, left teat circumference, right teat circumference and teat angle. The data was collected from 27 Norduz goats raised in pastoral conditions in the Norduz region of Van province South Eastern Turkey. Factor analysis was employed to simplify the complex relationships between udder traits. After the udder traits were exposed to factor analysis, four factors with Eigen values greater than 1 were selected as explanatory (independent) variables and used for multiple linear regression analysis. First factor was named teat factor, second and third factors were named udder factors while the fourth was udder bottom height. The 2nd and 3rd factors, which were significant, were then used to fit the regression model. The study found that two udder factors had significant statistical effect on daily milk yield and these factors together had accounted for 78.6 % of the variation in daily milk yield. The findings of this study showed that both multivariate and univariate approaches can be used to determine the relationship between milk yield and udder traits. In addition, these statistical approaches may also be useful to eliminate multicollinearity problems among large number of variables. In conclusion, the study proved that both univariate and multivariate methods can be applied successfully to predict daily milk yield using udder traits in goats.
