Abstract

Summary: This study was conducted to compare the effect of estrus detection using progesterone test kits and clinical examination on the conception rate, and to investigate whether the progesterone tests have positive effect on conception rate of cows in field conditions. A total of 136 cows were used in this study. The clinical findings of estrus in cows were examined by visual observation and rectal palpation. Cows were divided into three subgroups considering to the intensity of clinical results. Progesterone levels in serum samples were evaluated using progesterone test (Ovulation Test®) kits. Cows were also divided into three subgroups according to the progesteron levels, and then, all cows were artificially inseminated. The conception rates were determined by rectal palpation on 55-60th days following artificial insemination. In this study, the mean overall conception rate was recorded as 65.4%. It has been found that there is no difference (P>0.05) among conception rates of cows which were divided into subgroups by intensity of clinical findings. The conception rates were significantly (P<0.05) higher in cows with low concentrations of progesterone (<1 ng/ml) at insemination time than those of cows with intermediate concentrations of progesterone (1- 2.5 ng/ml) (78.5% vs. 23.8%). In addition, the conception didn't occur in cows with high concentrations of progesterone (>2.5 ng/ml). In conclusion, the use of practice progesterone tests can be useful for preventing errors in heat detection and for increasing conception rate in cows which not be detected in estrus by clinical examination.

Özet

Özet: Bu çalışma, klinik muayene ve progesteron test kitleri ile yapılan östrus teşhisinin gebelik oranları üzerine etkisini karşılaştırmak ve yapılan progesteron testlerinin saha şartlarında ineklerin gebelik oranları üzerine olumlu bir etkisinin olup olmadığını araştırmak amacıyla yapıldı. Bu araştırmada materyal olarak 136 inek kullanıldı. Gözlem ve rektal palpasyon yoluyla hayvanlardaki östrusa ait klinik bulgular incelendi. Klinik bulguların şiddetine göre inekler üç alt grupta değerlendirildi. Alınan serum örneklerinde progesteron test (Ovulation Test®) kitleri kullanılarak progesteron seviyeleri belirlendi. Progesteron düzeylerine göre de hayvanlar üç alt gruba ayrıldı. Daha sonra hayvanların hepsi suni tohumlama yöntemiyle tohumlandı. Tohumlamayı takip eden 55-60. günlerde rektal palpasyon yöntemiyle gebelikler teşhis edildi. Bu çalışmada, ortalama gebelik oranı %65.4 olarak kaydedildi. Klinik bulguların şiddetine göre gruplara ayrılan ineklerin gebelik oranları arasında herhangi bir farklılık (P>0.05) bulunmadı. Tohumlama anında progesteron düzeyi düşük olan ( 2.5 ng/ml) ineklerden gebelik elde edilemedi. Sonuç olarak, klinik muayene ile östrusta olduğu belirlenemeyen ineklerde, östrus teşhisindeki hataların önlemesi ve gebelik oranlarının artırılması amacıyla pratik progesteron testlerinin kullanılması faydalı olabilir.
