İngiliz Atlarında Bazı Doğum ve Doğuma İlişkin Özellikler ile Tay Davranışları

Abstract Some parturition traits and foal behaviors of Thoroughbred horses This study has been performed to determine the behavioural characteristics of some births and some of the factors that affect them for Throughbred mares. The research has been carried out in Adana Yavuz Star Farm between the years 2021-2022 and several characteristics of a total of 63 head mares and their foals were followed. In the study, it has been determined that the average live weight (LW) was 499,27±3,68 kg, the time of birth was 14,63±1,28 min, colostrum percentage was 23.81±0.69 min, the expelling time for placental partner was 126,57±28,92 and the placental weight was 6,47±20 kg. It has been concluded that the incidence of deliveries increased between 18.00 and 24.00 (36,51%) and the effect of birth year and time (night, day) has an significant effect on the birth duration. The average birth weight of foals, the time to stand up and the time to the first suckling was 54,34, 1,01 kg, 87,19±7,92 and 114,24±11,96 min, respectively. It was concluded that the all of the factors that have been examined has a significant effect on the time of the first stand (P˂0,05; 0,05; 0,01, respectively). The result of the study indicates the effect of examined factors on the time of the first stand up and the time until the first suckling in the foals.This study has been performed to determine the behavioral characteristics of some births and some of the factors that affect them for Thoroughbred mares. The research has been carried out at Adana Yavuz Star Farm between the years 2021-2022 and several characteristics of a total of 63 head mares and their foals were followed. In the study, it has been determined that the average live weight (LW) was 499.27±3.68 kg, the time of birth was 14.63±1.28 min, colostrum density was 23.81±0.69 min, the expelling time for placental partner was 126.57±28.92 min, and the placental weight was 6.47±20 kg. It has been concluded that the incidence of deliveries increased between 18.00 and 24.00 (36.5%), and the effect of birth year and time (night, day) has a significant effect on the birth duration (P=0.004; P = 0.010). The average birth weight of foals, the time to stand up, and the time to the first suckling were 54.34±1.01 kg, 87.19±7.92, and 114.24±11.96 min, respectively. It was concluded that all examined factors have a significant effect on the time of the first stand (P=0.018; P=0.027; P=0.032; P=0.005; P=0.004). As a result, the time to first stand up and suck in foals is affected by gender and birth time; in addition, the high frequency of blood incompatibility, poor colostrum quality, and prolonged throwing out of the placenta have been determined.

Bu çalışma Safkan İngiliz kısraklarda bazı doğum ve taylarında davranış özellikleri ile bunlara etkisi olan bazı faktörlerin belirlenmesi amacı ile yapılmıştır. Araştırma, Adana Yavuz Star Harasında 2021-2022 yılları arasında yürütülmüş olup toplam 63 kısrağın ve bunların taylarının bazı özellikleri takip edilmiştir. Çalışmada kısraklarda ortalama canlı ağırlık (CA) 499.27±3.68 kg, doğum süresi 14.63±1.28 dk, kolostrum yoğunluğu %23.81±0.69, eş atma süresi 126.57±28.92 dk ve plasenta ağırlığının 6.47±0.20 kg olduğu belirlenmiştir. Doğumların görülme sıklığının 18.00 ve 24.00 saatleri arasında arttığı (%36.5) ve doğum yılı ile zamanının (Gece, Gündüz) doğum süresine etkisinin önemli (P=0.004; P=0.010) olduğu tespit edilmiştir. Taylarda doğum ağırlığı, ilk ayağa kalkmaya kadar geçen süre ve ilk emmeye kadar geçen sürelerin ortalamaları sırasıyla 54.34±1.01 kg, 87.19±7.92 ve 114.24±11.96 dk olmuştur. Doğum yılı, doğum ayı, kısrak yaşı, cinsiyet ve doğum zamanının ilk ayağa kalkma süresi üzerine etkisinin önemli (P=0.018; P=0.027; P=0.032; P=0.005; P=0.004) olduğu belirlenmiştir. Sonuç olarak, taylarda ilk ayağa kalkma ve ilk emmeye kadar geçen sürelerin tay cinsiyeti ve doğum zamanından etkilendiği; kan uyuşmazlığı, kolostrum kalitesi düşüklüğü ve eş atma süresinin uzaması problemlerinin görülme sıklığının yüksek olduğu belirlenmiştir.
