摘要

本研究旨在确定品种和季节对AI公牛精液质量的影响。使用的材料是2010年至2020年期间收集的85头豪华轿车和88头西门塔尔公牛的n= 78,648份射精记录。研究中评估的精液质量包括:射精量(Vol)、pH值、单个精子活力(ISM)、精子浓度(SC)和解冻后活力(PTM)。采用混合模型对数据进行分析，其中品种和季节为固定效应，动物为随机效应。Vol、ISM、SC和PTM受季节影响显著(p< 0.05)，而Vol、SC和PTM受季节和品种的交互作用影响。西门塔尔公牛的精液质量普遍优于利姆塞纳公牛。同样的结果在不同季节也存在显著差异。Simmental的Vol、ISM、SC和PTM分别为6.48±1.26、64.22±1.16、1108±0.46和42.19±0.38。湿润季节Vol和SC的增加对ISM的影响不成比例。

Seasonal effect on semen quality of Limousine and Simmental bulls

This study aimed to determine the effect of breed and season on the semen quality of AI bulls. The material used was n= 78,648 records of ejaculated semen from 85 Limousine and 88 Simmental bulls collected between period 2010 and 2020. Semen qualities evaluated in the study were: ejaculate vol-ume (Vol), pH, individual sperm motility (ISM), sperm concentration (SC), and post-thawing motility (PTM). The data was analyzed by using a MIXED model with breeds and seasons as fixed effects and animals as random effects. The seasons were significant (p<0,05) on Vol, ISM, SC, and PTM, then the interaction between season and breed was affected on Vol, SC, and PTM. Simmental bulls generally showed better semen qualities than Limousine bulls. Further, the same result showed significant differ-ences in each season. The Vol, ISM, SC, and PTM of Simmental were 6.48 ± 1.26, 64.22 ± 1.16, 1,108 ± 0.46, and 42.19 ± 0.38, respectively. The increase of Vol and SC in the humid season has not propor-tionally affected ISM.

期刊介绍： Journal of the Indonesian Tropical Animal Agriculture (JITAA) is a double blind peer-reviewed publication devoted to disseminate all information contributing to the understanding and development of animal agriculture in the tropics by publication of original research papers. The journal covers all aspect relating to Animal Agriculture, including: -Animal breeding and genetics -Animal feeding and nutrition -Animal reproduction -Animal biotechnology -Animal physiology -Animal production and technology -Animal products technology -Animal management and economics -Animal products processing and animal by-products -Animal microbiology -Livestock farming systems -Other related topics in relation to animal science. The topics of research are not only on Indonesian tropical animal agriculture, but also on other tropical regions of the world.
