摘要
Abstract
[ Objective ] Earlier identification of pregnant and non-pregnant animals post breeding can greatly improve reproductive efficiency and pregnancy rate and decrease the interval between .services. The experiment was conducted to develop a rapid and simple early pregnancy diagnostic method in sheep. [ Method ] The early pregnancy diagnosis was conducted with serum acid titration in 1 317 female sheep (Duolang sheep, Cele sheep and Karakul sheep) after 16 -30 d post artificial insemination. [ Result] After the serum acid titration, 1 128 pregnant ewes and 189 non-pregnant ewes were detected in the three sheep breeds. Compared with the actual pregnancy detection, the coincidence rate of pregnancy was 89.88％ ( 1 013/1 128); the coincidence rate of non-pregnancy was 96.83％ (183/189); and the total coincidence rate was 90.81％ (1 196/1 317). Chi-square test analysis showed that no significant difference (P ＜ 0.05 ) was found between the three sheep breeds or between any two breeds. [ Conclusion ] This serum acid titration is a simple, convenient and highly accurate method for early pregnancy diagnosis in sheep, which shows highly practical and popularizing value.关键词
