Holstayn Sığırlarda Kızgınlık Tespitinde Tükürük Kurutma Testlerinin Kullanılması

Sunulan çalışmada uygulanması kolay ve maliyeti düşük olan tükürük kurutma (kristalizasyon) testleri sonucu oluşan ağaçlanma veya eğrelti otu görünümünün yaygınlığının holstayn ırkı sığırlarda östrusta ve diöstrusta değişip değişmediği dolaysıyla östrus döneminin taininde bu yöntemin kullanılıp kullanılamayacağı araştırıldı. Bu amaçla östrusta olduğu belirlenen (n:14) ve diöstrusta olduğu bilinen (n:11) holstayn sığırlardan alınan numuneler incelendi. Sonuçlar “yok”, “yüzlek” ve “belirgin” olarak 3 gruba ayrıldı. Östrustaki sığırların %71.4’ünde diöstrustaki sığıların % 18.2’ sinde ağaçlanma veya eğrelti otu görünümünün belirgin olduğu ve aradaki farkın anlamlı olduğu belirlenmiştir. Östrustaki sığırların % 14.3 ‘ ünde diöstrustaki sığırların % 63.6’sında ağaçlanma veya eğrelti otu görünümünün yüzlek olduğu ve aradaki farkın anlamlı olduğu belirlenmiştir. Östrustaki sığırların % 14.3’ünde diöstrustaki sığırların % 18.2’sinde ağaçlanma veya eğrelti otu görünümünün bulunmadığı ve gruplar arasındaki farkın önemsiz olduğu belirlenmiştir. Sonuç olarak tükürük kurutma testi sonuçlarına göre holstayn ırkı sığırlarda östrus döneminin diöstrus döneminden ayırt edilebileceği kanısına varılmıştır.

The Use of Saliva Drying Tests for Detection of Oestrus in Holstayn Cattle

In the present study, it was investigated whether this method can be used in the estrus period, as the prevalence of woody or fern appearance, which is the result of easy-to-apply and low-cost saliva drying (crystallization) tests, changes in estrus and diestrus in holstein cattle. For this purpose, samples taken from holstay cattle, which were determined to be in estrus (n:14) and known to be in diestrus (n:11), were examined. The results were divided into 3 groups as "absent", "outlier" and "significant". It was determined that 71.4% of the cattle in estrus and 18.2% of the cattle in diestrus had a woody or fern appearance and the difference was significant. It was determined that 14.3% of the cattle in estrus and 63.6% of the cattle in diestrus had an outcrop or fern appearance and the difference was significant. It was determined that 14.3% of cattle in estrus and 18.2% of cattle in diestrus did not have woody or fern appearance, and the difference between the groups was insignificant.. As a result, according to the results of the saliva drying test, it was concluded that the estrus period in holstein cattle can be distinguished from the diestrus period.
