Abstract

Objective: This study aimed to determine the effects of biologically active substances and electrical stimulation of the uterus in cows on the effectiveness of estrus synchronization.

Materials and methods: Ninety (n = 90) Kazakh white-headed cows were synchronized with two injections of gonadotropin-releasing hormone on days 0 and 9 and prostaglandin F2α on day 7. The cows were divided into six groups and, during the protocol, treated with biologically active substances (Tetramag, Selevetum, antiseptic-stimulator Dorogov 2 fraction, groups 2, 3, and 4). Cows in groups 5 and 6 were treated with the same substances but additionally had electrical stimulation of the uterus, while cows in group 1 were left untreated and served as a control.

Results: The results have shown that on Day 0, no differences were observed in E2 concentrations between the groups. However, on the 10th day, a significant disparity was noted in the E2 level among cows in group 6 compared to groups 2, 3, 4, and the control group. Conversely, no significant differences were observed between groups 5 and 6. Likewise, the fertility rate in cows from group 6 was significantly higher compared to groups 2, 3, 4, and the control group, with no significant differences between groups 5 and 6.

Conclusion: It can be concluded that the utilization of electrical stimulation of the uterus and the inclusion of certain biological substances during the estrus synchronization protocol demonstrate a positive effect on the reproductive performance of beef cattle in Kazakhstan.

提高奶牛同步发情的效率。

研究目的本研究旨在确定生物活性物质和对母牛子宫的电刺激对同步发情效果的影响：在第 0 天和第 9 天注射两次促性腺激素释放激素，在第 7 天注射前列腺素 F2α，对 90 头哈萨克白头奶牛（n = 90）进行同步发情。奶牛被分为六组，并在方案期间接受生物活性物质治疗（Tetramag、Selevetum、抗菌刺激剂 Dorogov 2 fraction，第 2、3 和 4 组）。第 5 组和第 6 组的奶牛接受了相同物质的治疗，但另外对子宫进行了电刺激，而第 1 组的奶牛则未接受治疗，作为对照：结果表明，第 0 天，各组之间的 E2 浓度没有差异。但在第 10 天，第 6 组奶牛的 E2 水平与第 2 组、第 3 组、第 4 组和对照组相比有显著差异。相反，第 5 组和第 6 组之间没有发现明显差异。同样，与第 2、3、4 组和对照组相比，第 6 组奶牛的受胎率明显较高，而第 5 和第 6 组之间没有明显差异：可以得出结论，在发情同步方案中使用子宫电刺激和加入某些生物物质对哈萨克斯坦肉牛的繁殖性能有积极影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
