In this study, fertilization parameters of 102 head Norduz and 583 head Awassi with fresh and undiluted semen by artificial insemination were determined. Morning, evening and total estrus detection were respectively; In the Norduz, 47 ± 0.23 head (47.96 %) - 34 ± 0.16 head (34.69 %) and 81 ± 0.20 head (82.65 %), In the Awassi, 359 ± 0.97 head (61.58  %) - 197 ± 0.63 head (33.79 %) and 556 ± 0.8 head (95.37 %). Those who show no estrus in Norduz and Awassi were respectively; 17 ± 0.18 head and (17.35 %) - 27 ± 0.21 head (4.63 %). After 11.0 hours of estrus detection artificial insemination with fresh and undiluted semen of 0.3 ml / head dose into the cervical mouth (os cervical) were performed. Mean yield parameters, Norduz and Awassi in respectively; ate on lambing rate the length of pregnancy 157.6±3.38 - 153.1±1.81day, the single lambing 51±1.17 head (62.97 %) - 387±1.13 head (69.60 %), the twins lambing 12±1.06 head (14.82 %) - 103±1.22 head (18.53 %), and the total lambing head and rate on 63±1.12 head (77.79 %) - 490±1.18 head (88.13 %) rate were determined. In terms of fertilization parameters of artificial insemination with fresh and undiluted semen, Awassi yearling were significantly higher than Norduz ewe (P≤0.01). According to this, it can be said that Awassi yearlings can be used as effective breeding material in the breeding of domestic sheep breeds with their high adaptability, milk and progeny yield characteristics.

Taze ve Sulandırılmamış Sperma ile Yapay Tohumlanan Yerli Koyunların Döl Verim Özellikleri

Öz

Bu araştırmada, 102 baş Norduz ve 587 baş İvesi kullanılarak,
taze ve sulandırılmamış sperma ile yapay tohumlama döl verim parametreleri belirlenmiştir.
Sabah, akşam ve toplam kızgınlık tespitleri sırası ile; Norduz’larda 47 ± 0.23
baş (% 47.96) - 34 ± 0.16 baş (% 34.69) ve 81 ± 0.20 baş (% 82.65), İvesi’lerde
359 ± 0.97 baş (% 61.58) - 197 ± 0.63 baş (% 33.79) ve 556 ± 0.8 baş (% 95.37) belirlenmiştir.
Hiç kızgınlık göstermeyen, Norduz ve İvesi’ler sırası ile; 17 ± 0.18 baş (%
17.35) ve 27 ± 0.21 baş (% 4.63) belirlenmiştir. Kızgınlık tespitinden, 11.0
saat sonra, serviks ağzına (os cervical) 0.3 ml/baş doz taze ve sulandırılmamış
sperma ile yapay tohumlama yapılmıştır. Döl verim parametreleri ortalamaları, Norduz
ve İvesilerde sırası ile; gebelik süresi 157.6±3.38 - 153.1±1.81 gün,
tek doğum 51±1.17 baş (% 62.97) - 387±1.13 baş (% 69.60), ikiz doğum 12±1.06 baş (% 14.82) - 103±1.22 baş (%
18.53) ve genel kuzulama oranı 63±1.12 baş (% 77.79) - 490±1.18 baş (%
88.13) olarak belirlenmiştir. Taze ve sulandırılmamış sperma ile yapay tohumlama
döl verim parametreleri bakımından, İvesi toklular, Norduz koyunlarından, istatistiki
olarak önemli düzeyde yüksek bulunmuştur (P≤0.01). Buna göre, İvesi’lerin
yüksek adaptasyon, süt ve döl verim özellikleri ile, yerli koyun ırklarının
ıslahında, etkin damızlık materyali olarak kullanılabilecekleri söylenebilir.
