    CHANGES OF THYROID HORMONES IN DIFFERENT PHYSIOLOGICAL PERIODS IN WHITE GOATS
    (Pakistan Agricultural Scientists Forum, 2014) Polat, H.; Dellal, G.; Baritci, I.; Pehlivan, E.
    The levels of thyroid hormones are important indicator of metabolic activity. The knowledge of the metabolic activity in different physiological periods, animals readjusted dietary regimen. Therefore, in this study, changes of triiodotironine (T3) and thyroxine (T4) hormones in the blood serum of female (n=14) and male (n=9) white goats were studied for a duration of one year through different physiological periods [breeding (September-October), gestation (November to March), postpartum-sucking (April-May) and milking (June to August)]. Results show that the differences in T3 and T4 hormone levels between sexes are statistically unimportant in breeding, gestation, postpartum-sucking and milking periods, while the changes for each sex between the physiological periods are important (p<0.05). Also, it has been found out that the thyroid hormone levels in different physiological periods are under the influence of the environmental temperature changes.

    COMPARATIVE ANALYSIS OF VARIOUS FLEECE CHARACTERISTICS OF NORDUZ AND ZOM SHEEP
    (Pakistan Agricultural Scientists Forum, 2017) Tuncer, S. S.; Sireli, H. D.; Dellal, G.
    This research aimed to evaluate the fleece samples obtained from the shoulder, rump and flank areas of Norduz and Zom sheep. The study consisted of 25 Norduz sheep and 24 Zom sheep. The longest hauteur fleece in Norduz and Zom sheep was obtained from the rump area (40.30 +/- 2.96 and 30.11 +/- 1.50 mm) and the longest barbe fleece was obtained from the rump area (58.22 +/- 4.70 and 42.28 +/- 3.10 mm). Upon examination of the fiber diameter of the fleece of the Norduz and Zom sheep, the thickest fleece was found in the rump area (35.73 +/- 1.13 and 33.01 +/- 0.86 mu), with the fleece in the other areas finer and closer together. In both breeds (Norduz and Zom), the fleece obtained from the flank had the highest elasticity (32.17 +/- 0.83 and 31.44 +/- 1.01%), and the fleece obtained from the rump had the highest strength (33.91 +/- 2.03 and 24.33 +/- 2.03 cN/tex). In both the Norduz and Zom sheep, the highest fleece yields were obtained from the flanks: 63.58 +/- 1.52 and 62.96 +/- 2.27%. This study revealed no marked variation in the fleece yields and characteristics of the Norduz and Zom sheep, which are thought to be a variety of the White Karaman sheep.
