Abstract

The aim of this study was to evaluate the reproductive parameters of dairy cows treated with reproductive hormones using the single ovulation synchronization (ovsynch) and double ovulation synchronization (double ovsynch) methods. This study used 33 article journals with parameters estrus percentage, ovulation percentage, corpus luteum formation percentage, pregnancy rate, conception rate and progesterone level. The article journals used of latest 35 years from 1990 to 2025. The methods used is meta-analysis. R Studio 4.4.2. were used for tools of statistical analysis. The results showed that the double ovsynch method is significantly effective (P<0.05) compared with ovsynch for estrus percentage, ovulation percentage and conception rate. Meanwhile, regarding the corpus luteum formation percentage, pregnancy rate and progesterone level showed that the double ovsynch method have no significant differences (P>0.05) compared with ovsynch. The conclusion of this research is the double ovsynch method was optimum than ovsynch method.
