It is based on DIKTI accreditation standard and covers all aspects of agricultural researches including Animal Science and Fisheries, Agribusiness, Agricultural Technology, and Agriculture and Bioscience. Manuscripts with either basic, applied, and advance studies are accepted. Each of the manuscripts need to be completed with well design method and systematic review on previous works. This journal aims to provide academic insights for policy makers, as well as valuable references for further studies.

The quality of the semen used plays an important role as a factor in the success of artificial insemination (AI) programs. Climate change, including temperature variations, rainfall, and length of solar exposure, can affect the quality of fresh semen produced by bulls. Differences in environmental conditions can affect semen characteristics, such as spermatozoa concentration, motility, and morphology, which in turn have an impact on the field fertility rate. The aim of this study is to explore the differences in male fertility based on environmental conditions that change throughout the seasons. The research method used in this study is non-experimental, using secondary data on the quality of fresh semen and frozen semen production collected from the Regional AI Center, Bali Province. In addition, this study also used data from the big data of the National Animal Health Information System (iSIKHNAS) to calculate field fertility represented by conception rate. Climate data was obtained from the Indonesian Agency for Meteorological, Climatological and Geophysics (BMKG) Bali Province, the data collected was climate data in Tabanan Regency. The differences in the appearance of fresh semen quality, frozen semen production, and field fertility were analyzed using the Independent T-Test. In this study, there was no significant difference in fresh semen quality, frozen semen production, and field fertility (P&gt;0.05) in all parameters, but the average reproductive performance of bali bulls was higher in the rainy season than in the dry season.</p> </div> Dian Tria Fatmila, Yudi, Bambang Purwantara, Fuad Hasan, Wahyudi Himawan Sutanto Copyright (c) 2025 Indonesian Journal of Agricultural Research https://creativecommons.org/licenses/by-nc-sa/4.0 https://talenta.usu.ac.id/InJAR/article/view/20096 Thu, 10 Jul 2025 00:00:00 +0700 Examining small-scale cattle farmers’ willingness to participate in livestock auction markets in Bushbuckridge Local Municipality https://talenta.usu.ac.id/InJAR/article/view/15536 <p>This study explored the willingness of small-scale cattle farmers in Bushbuckridge Local Municipality, Mpumalanga Province, South Africa, to participate in livestock auction markets. Agriculture, a cornerstone of economies, heavily relies on livestock farming in South Africa. However, small-scale cattle farmers face challenges in market participation. The study investigated the factors influencing farmers' willingness, emphasizing socio-economic characteristics. Using descriptive statistics and logistic regression, the research unveils significant factors, providing insights for targeted interventions. The logistic regression model indicates a statistically significant relationship between education level, farm size, access to agricultural information, farming experience, and farmers' willingness to engage in auction markets. Notably, higher education levels and larger farm sizes positively correlate with willingness, while increased access to agricultural information and excessive farming experience exhibit negative correlations. The findings have crucial implications for policy interventions, suggesting the need for educational programs to enhance farmers' awareness of auction markets, initiatives to increase farm sizes, and improved dissemination of agricultural market information.</p> Zanele Nonhlanhla Nyembe, Jan Johannes Hlongwane, Rudzani Nengovhela Copyright (c) 2025 Indonesian Journal of Agricultural Research https://creativecommons.org/licenses/by-nc-sa/4.0 https://talenta.usu.ac.id/InJAR/article/view/15536 Thu, 10 Jul 2025 00:00:00 +0700
