We previously developed a rapid analytical method for measuring blood retinol concentration that eliminates the process of blood cell separation. However, achieving a strong correlation with actual retinol levels proved challenging due to the requirements of vigorous agitation of blood and n-hexane using a vortex mixer. Consequently, in this study, we developed a modified method that does not require intense agitation by adding phosphate-buffered saline (PBS) to the blood and n-hexane mixture. The addition of PBS facilitated the dispersion of whole blood in n-hexane, although the augmented interface between the two enhanced extraction efficiency. Furthermore, we conducted field tests using blood samples collected from 98 fattening cattle from six different farms, each using distinct feeding methods and rearing environments, to reflect the diverse feeding practices in Japanese Black beef production. Their retinol concentrations were analyzed using the developed method and compared with values obtained by HPLC. A correlation coefficient of 0.94–0.96 was obtained, indicating that blood retinol levels can be reliably measured even among farms with different feeding methods.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"96 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/asj.70069","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144220128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mean pH24h was 5.60, and the dark-cutting percentage was 13.20%. The effect of management type on the presence of dark cutting was significant (p = 0.047). The mean pH24h value was higher in cattle from the nontethered management group (G-I, 5.642) than in cattle from the tethered group (G-II, 5.579). The presence of dark cutting was 2.519 times higher in the G-I cattle than in the cattle in Group IV (tethered during unloading and at the lairage and nontethered at the slaughter corridor). The effects of season, sex, season × sex, season × management type, sex × management type, age, trackload density, and carcass weight on pH24h were significant. In conclusion, the tethered management type may contribute to reducing the presence of dark cutting in slaughterhouses that were established without considering animal behaviors and ease of cattle handling.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"96 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/asj.70073","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144206385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the impact of elevated postpartum somatic cell scores (SCS) in primiparous cows on herd productivity, aiming to inform milk quality improvement measures in Hokkaido. Production data from 163 herds in Eastern Hokkaido were analyzed, with milk yield per cow, herd SCC, and mortality used as dependent variables and primiparous cow SCS as the independent variable. Results revealed a significant positive association between primiparous cow SCS and both herd SCC and mortality, whereas a significant negative association was observed with milk yield per cow. These findings suggest that high SCS in primiparous cows may reflect suboptimal animal welfare practices, such as poor udder hygiene and inadequate peripartum management. Enhancing welfare practices, such as udder hygiene, and providing a supportive calving environment could improve SCS in primiparous cows, increase milk productivity, and reduce mortality.

This panting causes respiratory hypocapnia, which increases the renal excretion of buffer molecules including sodium, potassium, and bicarbonate. In response, renal acid excretion decreases to preserve acidity. Besides hypocapnia, lactation and HTa could further deplete buffer molecules, enhancing acid preservation. This current study restored buffer molecules using high dietary cation and anion difference (DCAD) regimen and hypothesized that renal acid excretion during acute acid load would be increased in dairy goats fed high DCAD under HTa. To investigate this, 12 early-lactating dairy goats were randomly assigned to two groups: control and DCAD, which were fed control and high-DCAD diets, respectively, for 8 weeks. Acute acid loading during HTa was induced by high-dose ascorbic acid (AA) supplementation. During Weeks 4 and 8, the vehicle and AA were supplemented on the last two consecutive days of each week. The results showed that the renal acid excretion in DCAD group was higher than control group during high-dose AA supplementation. Together with high renal buffer excretion by DCAD, an increased renal acid excretion may be partially mediated by an increase in buffer reserve.\u0000 </div>","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"96 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930515","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}
