Twelve clinically healthy WAD bucks were randomly assigned into two groups, each receiving 0 mL (control), and 4 mL of PNLE, respectively, over a 21-day period. Blood and semen samples were collected at baseline and post-treatment to evaluate antioxidant markers including catalase, superoxide dismutase (SOD), malondialdehyde (MDA), total antioxidant capacity (TAC), lipid peroxidation (LP), and glutathione peroxidase (GPx). An antioxidant response was observed. In the control group (0 mL PNLE), significant negative correlations between baseline and post-treatment values—particularly B-Cat. vs. SOD (r= -0.973), B-Cat. vs. MDA (r= -0.990), and B-MDA vs. SOD (r= -0.999)—suggested impaired endogenous antioxidant regulation. Conversely, administration of 4 mL PNLE significantly enhanced antioxidant status, with strong positive correlations among key indices, notably catalase vs. GPx (r= 0.960**) and TAC vs. SOD (r= 0.999**), reflecting improved systemic antioxidant synergy. Semen antioxidant profiles also showed better enzymatic coordination and reduced lipid peroxidation, indicating the extract’s potential to alleviate reproductive oxidative stress. Overall, <em>Parquetina nigrescens</em> (<em>P. nigrescens</em>) demonstrated marked antioxidative efficacy, supporting both systemic and reproductive redox balance in WAD goats. <em>P. nigrescens</em> leaf extract enhances seminal antioxidant status in WAD goats, thereby promoting reproductive and systemic health. This study recommends its inclusion as a phytogenic additive in goat production, especially in breeding programs prone to oxidative stress.</p> Lois Chidinma Ndubuisi-Ogbonna, Adeyinka Oye Akintunde, Oluwafikunayo Fareed Noibi, Oluwaseyi Emmanuel Oso Copyright (c) 2025 Lois Chidinma Ndubuisi-Ogbonna, Adeyinka Oye Akintunde, Oluwafikunayo Fareed Noibi, Oluwaseyi Emmanuel Oso http://creativecommons.org/licenses/by-sa/4.0 https://e-journal.unair.ac.id/OVZ/article/view/73016 Sun, 27 Jul 2025 00:00:00 +0700 Factors associated with repeat breeding in Holstein Friesian cows at the Tani Wilis Village Cooperative Unit, Sendang District, Tulungagung Regency, Indonesia https://e-journal.unair.ac.id/OVZ/article/view/68733 <p>This study aimed to evaluate the association of factors such as nutrition, thermal humidity index (THI), age, and lactation period with the occurrence of repeat breeding of dairy cows. The sample consisted of Holstein Friesian cows aged 1-11 years, with lactation periods ranging from 1 to 7 months, currently in lactation, and experiencing repeat breeding (inseminated three or more times without conception, despite exhibiting normal estrous cycles and intervals). The results showed that feeding practices by farmers did not significantly differ (p &gt;0.05) in relation to the incidence of repeat breeding. THI values recorded in several barns also showed no significant differences (p &gt;0.05), with the cows experiencing light to moderate heat stress. Similarly, the frequency of artificial insemination and the estrous cycle intervals remained within the normal range. The highest incidence of repeat breeding was observed in cows aged 2.5 to 5.5 years, accounting for 78.13%, and during lactation periods of 1-3 months, accounting for 81.26%. It can be concluded that there were no significant differences in the provision of forage and leguminous feed between normal cows and those with repeat breeding, and the crude protein content of forage did not influence its occurrence. Additionally, there was no indirect relationship between THI and repeat breeding. However, the incidence of repeat breeding tended to increase in cows aged 3-4 years, and during the second and third lactation periods.</p> Dimas Kunto Satrio, M’ Izi Kumala Lazuardi Sultoni, Tasya Apritalia Putri, Soeharsono Soeharsono, Dadik Rahardjo, Djoko Legowo, Gandul Atik Yuliani, Iwan Sahrial Hamid, Mohammad Anam Al-Arif, Sunaryo Hadi Warsito, Pudji Srianto, Sri Pantja Madyawati, Tita Damayanti Lestari, Wurlina Wurlina Copyright (c) 2025 Dimas Kunto Satrio, M’ Izi Kumala Lazuardi Sultoni, Tasya Apritalia Putri, Soeharsono Soeharsono, Dadik Rahardjo, Djoko Legowo, Gandul Atik Yuliani, Iwan Sahrial Hamid, Mohammad Anam Al-Arif, Sunaryo Hadi Warsito, Pudji Srianto, Sri Pantja Madyawati, Tita Damayanti Lestari, Wurlina Wurlina http://creativecommons.org/licenses/by-sa/4.0 https://e-journal.unair.ac.id/OVZ/article/view/68733 Sun, 27 Jul 2025 00:00:00 +0700
