Abstract

One of the strategies to increase the cattle population in Indonesia is the IB (artificial insemination) method. The AI program's improvement of reproductive efficiency can use the estrus synchronization method. The purpose of this study was to see the effect of body weight and body condition score on the estrus synchronization response with the brand "lutelyse." This research was conducted in Senggreng Village, Sumberpucung District, Malang Regency, by conducting field experiment research methods. This study took a sample of 21 female broodstock synchronized with PGF2α as much as 2 ml, which was then carried out by observing estrus behavior for 24 hours after synchronization. Based on the study results, the percentage of oestrus in cows with BCS 4, which is 76.92%, is lower than cows with BCS 5, which is 100%. For the synchronization distance with the onset of estrus in BCS 4 cattle, namely 3802.92 ± 1007.80 (minutes) and BCS 5, namely 4081 ± 884.91 (minutes) with the results of the conception rate of BCS 4 cattle of 38.46% and BCS 5 of 50%. This study concludes that BCS 5 has a higher success rate than BCS 4.

牛生产性能对PGF2α单剂量同步发情反应的影响

在印度尼西亚，增加牛数量的策略之一是人工授精(IB)方法。人工智能程序对生殖效率的提高可以采用发情同步的方法。本研究的目的是观察体重和身体状况评分对“黄体素”品牌发情同步反应的影响。本研究采用田间试验研究方法，在玛琅县森伯普贡区升岭村进行。本研究选取了21只与PGF2α同步的雌亲鱼，并在同步后的24小时内观察其发情行为。从研究结果来看，BCS 4型奶牛的发情率为76.92%，低于BCS 5型奶牛的发情率100%。BCS 4牛与发情开始的同步距离为3802.92±1007.80 (min)， BCS 5牛为4081±884.91 (min)，结果BCS 4牛受孕率为38.46%，BCS 5为50%。本研究的结论是BCS 5的成功率高于BCS 4。
