Impacts of climate parameters on physiological characteristics of Karayaka sheep

Bu çalışma soğuk kış koşullarında iklim parametreleri ile Karayaka koç ve koyunlarının adaptasyon parametreleri değişimlerinin incelenmesi, birbirlerine olan etkilerinin belirlenmesi ve fizyolojik tepkilerinin ortaya konması amacıyla yapılmıştır. Erkek ve dişi bireylerde ortalama vücut sıcaklığı sırasıyla sabah 39.51°C, 39.31°C; akşam 39.64°C, 39.50°C; nabız sayısı sabah 88.86 adet/dak, 83.04 adet/dak; akşam 91.68 adet/dak, 86.96 adet/dak, solunum sayısı sabah 39.71 adet/dak, 43.06 adet/dak; akşam 41.36 adet/dak, 44.35 adet/dak olarak belirlenmiştir. Vücut sıcaklığı, nabız sayısı ve solunum sayısı ortalaması üzerine cinsiyet ve ölçüm zamanının etkisi önemli (P0.05). Bağıl nem ve fizyolojik parametreler arasında negatif bir korelasyon tespit edilmiş, rüzgar hızı ile fizyolojik parametreler arasında belirlenen korelasyonlar istatistiki olarak önemsiz bulunmuştur (P>0.05).

İklim parametrelerinin Karayaka koyunlarının fizyolojik özellikleri üzerine etkisi

Objectives of this research were to investigate the variations in adaptation parameters of Karayaka rams and ewes to cold winter conditions, to determine mutual interactions among them and to put forward their physiological responses against climate parameters. Average body temperatures of rams and ewes were respectively determined as 39.51°C and 39.31°C in the morning, 39.64°C and 39.50°C in the evening; pulse rates were determined as 88.86 and 83.04 pulse/min in the morning, 91.68 and 86.96 pulse/min in the evening; respiration rates were determined as 39.71 and 43.06 times/min in the morning, 41.36 and 44.35 times/min in the evening. Effects of sex and measuring time on body temperature, pulse and respiration rates were found to be significant (P<0.01), interaction between sex and measuring time was found to be insignificant (P>0.05). A negative correlation was observed between relative humidity and physiological parameters. Correlations between air velocities and physiological parameters were found to be insignificant (P>0.05).
