The apparent nutrient digestibility was higher in CS diets than in the CON diet. The CS diets showed significantly lower urinary N excretion rate with their higher N retention rate compared with CON, indicating improved N utilization efficiency in CS diets. Compared with CON, CS2 increased milk yield by 36%, and CS diets increased milk protein and fat content.

The study found that the mean CWT significantly increased from 76.1 to 77.1 kg (p < 0.05), with 77% of farms increasing their CWT. Statistical analysis revealed that farms that had increased their CWT by more than 2 kg saw a significantly higher increase in margin over feed cost per market pig compared with farms that had decreased their CWT (p < 0.05). This increased profit was primarily driven by higher sales revenue per market pig owing to the increased CWT, while feed cost per pig was statistically similar across all change groups. In conclusion, the CTSP revision successfully encouraged most farms to increase CWT, providing a clear economic advantage in terms of margin over feed cost.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"97 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12817232/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146002835","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}

We explored the relationship between vulvar BFV and follicular hormone dynamics in cows. Eleven Japanese Black cows underwent superovulation treatment, after which vulvar BFV, serum estradiol (E2) and progesterone levels, and follicle number were measured. All measurements were repeated in the luteal phase (7 days before estrus), 1 and 2 days before estrus, and 2 and 7 days after estrus. The vulvar BFV was significantly elevated 1 day before estrus compared with that during the luteal phase. Furthermore, the vulvar BFV dynamics mirrored the follicle number and serum E2 level, both of which were significantly elevated 1 day before estrus compared with those during the luteal phase. In addition, positive correlations were observed between vulvar BFV and follicle number, between serum E2 level and follicle number, and between vulvar BFV and E2 level. Thus, vulvar BFV measurements could serve as a practical and non-invasive strategy for predicting follicle number and may provide a valuable tool for farmers.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"97 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145904689","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}
