Furthermore, we assessed seminal plasma cortisol and testosterone concentrations in poor-quality and good-quality ejaculates. To evaluate bull performance, we categorized the bulls into two groups based on ejaculate discard rates: consistent (n = 9) and inconsistent semen quality bulls (n = 6). The breeding bulls' hair cortisol and testosterone levels were evaluated at two-month intervals for one year. We analyzed the semen from both groups for motility and kinematic parameters using a computer-assisted semen analyzer and acrosome integrity, mitochondrial membrane potential, and superoxide production through flow cytometry. The bulls that exhibited consistent semen quality had higher (P < 0.05) hair testosterone concentrations than those with inconsistent quality; however, there was no difference (P > 0.05) in hair cortisol levels between the two groups. Additionally, the ejaculates from bulls with inconsistent semen quality met minimum standards, showing no differences (P > 0.05) in sperm motility. However, mitochondrial membrane potential and superoxide production were compromised at the subcellular level. Acrosome integrity was also lower (P < 0.05) in bulls with inconsistent semen quality than those with consistent quality. In poor-quality ejaculates, regardless of the bull group, cortisol and testosterone concentrations were higher (P < 0.05) than in good-quality ejaculates intended for cryopreservation. Additionally, hair testosterone concentration increased with age in male calves, while hair cortisol levels were higher during July-August and lower from March to April.

Terpene and terpenoid rich extracts were isolated using a normal phase silica gel packed column and active fraction determined using repellence and knockdown effect. Ethyl acetate was used to extract the terpenes and terpenoids from dried Cissus quadrangularis stems. The chemical composition of the active fraction was evaluated using GC-MS. The formulated tick grease was evaluated under both laboratory and field studies. Out of the six column isolated fractions only 2, eluted with hexane: ethyl acetate ratio: 8:2 (100 mL), and 7:3 (100 mL), showed significant acaricidal activity with a percentage knockdown effect of 100 and 75% respectively. The GC-MS analysis of the combine two fractions showed that, they consisted of various monoterpenes and sesquiterpenes. Copaene (14.56%), α-ocimene (42.23%), murolene (16.98%) and caryophyllene oxide (11.89%) were found to be the major occurring compounds in the fraction.

The CF group showed lower (P < 0.05) respiratory rate on days 8, 10, 11, and 14. ADV and CF groups showed lower (P < 0.05) body weight loss during lactation. A tendency for decreased (P = 0.063) loss of back fat thickness in the CF group. ADV group shows higher (P < 0.05) weaned piglet weight and survivability. CF group showed lower hair cortisol concentration (P < 0.05) with higher (P < 0.05) piglet survivability. ADV and CF groups showed lower (P < 0.05) serum TNF-α level, also increased (P < 0.05) superoxide dismutase and malondialdehyde levels. In milk, the level of Fe, Mn, and Se increased (P < 0.05) in the ADV group. Also, feces excreted higher (P < 0.05) Zn, Fe, Mn, and Se. In conclusion, while both ADV and CF had beneficial effects, ADV posed a risk of increased mineral excretion. Given stricter regulations on dietary trace minerals, CF could be an effective strategy to enhance the performance of sows and piglets under HS.</p>","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 3","pages":"166"},"PeriodicalIF":1.7,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143811944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
