Öğe Different estrous induction protocols during the transition period in lactating Turkish Saanen does following Al(De Gruyter Open Ltd, 2008) Dogan, I; Konyali, A.; Tolu, C.; Yurdabak, S.The objective of this study was to evaluate the duration of three progestagen treatments for estrous synchronization in lactating Turkish Saanen goats during the transitional period from anestrous. All does (n = 60) were divided into three equal groups and the estrous period of the does was synchronized using intravaginal sponges (20 mg FGA) for either 11 days (Group 1), 9 days (Group 2) or 6 days (Group 3). In addition, 24h before sponge removal (on the 10(th) day, 8(th) day and 5(th) day, respectively) each doe was injected with 0.075 mg cloprostenol (PGF(2 alpha)) and 500 IU eCG. Cervical artificial inseminations (Al) with frozen-thawed semen were performed at fixed intervals (36 and 48 h) following progestagen withdrawal. The total estrous response following the first withdrawal was 12 +/- 6 h within 66 h. Time to onset and duration of the induced estrous, and pregnancy rates were recorded to be 30.0%, 100%, 23.9 +/- 0.7 h, 29.4 +/- 1.3 h, and 28.3%, respectively. There were significant differences between Group 1 and the other groups, in terms of the onset of induced estrus (P<0.05) and estrous response for the first 12 +/- 6 h (P<0.05) and between Group 2 and Groups 1 and 3 in terms of the duration of induced estrous (P<0.05). Each of the three protocols was effective in inducting and synchronizing estrus in lactating Turkish Saanen goats.Öğe Factors affecting placental traits and relationships of placental traits with neonatal behaviour in goat(Elsevier Science Bv, 2007) Konyali, A.; Tolu, C.; Das, G.; Savas, T.The relationships between placental characteristics and litter weight, factors affecting these characteristics, and the relationship between these characteristics and neonatal behaviour of goat kids were investigated in this study. The study was carried out over three consecutive years and animal material consisted of total 152 Turkish Saanen goats and their 230 kids. The results of the study demonstrated that there were positive correlations between litter weight (LW), cotyledon number (CN), placental weight (PW) (r=0.64 and 0.76, P < 0.01), but there was negative correlation between LW and cotyledon density (CD) (r=-0.42, P < 0.01). CD was negatively correlated with PW (r=-0.61, P < 0.01). CN and PW were influenced by the parity of doe, birth type-sex combination, buck within years and year of the study. On the other hand, parity and birth type-sex combination had no effect on PE (P > 0.05), but buck within year affected placental efficiency (P < 0.01). CD was only influenced by the parity of doe (P < 0.01). Duration of birth (D) was not significantly related with CD, but if CD declined, it prolonged (r=-0.23, P > 0.05). There were strong relationships between CD and birth-to-standing (B-St), and CD and birth-to-suckling (B-Su) (r=-0.42 and -0.51, P=0.01 and P < 0.01). The results of the present study have shown similarities to the findings of the studies in sheep. Further studies are required to investigate the basis of the relationship between CD and neonatal behaviour. (c) 2006 Elsevier B.V.
