Immunocastration, using products like Improvac®, offers an alternative to surgical castration, enabling the physiological advantages of rearing entire male pigs while addressing issues such as boar taint and animal welfare. This review analyzes the effects of immunocastration on the performance and carbon footprint of fattening pigs compared to entire males, gilts, and surgically castrated males. Data from 39 trials reported in research articles were used to extract information on average daily gain (ADG), feed conversion ratio (FCR), and mortality. The means of these parameters were used to calculate the carbon footprint. Results showed that immunocastrated males had a higher mean ADG and a lower mean FCR compared to gilts and surgically castrated males, resulting in 7.1% and 6.8% lower carbon footprints, respectively. However, entire males had a slightly lower carbon footprint than immunocastrated males due to a more favorable FCR, although differences were not statistically significant. The findings underscore the ecological advantage of immunocastration over surgical castration, driven by improved feed efficiency and growth rates. From a sustainability perspective, boar fattening offers the lowest environmental impact, but practical challenges like boar taint and behavioral issues remain. If boar fattening is not feasible, immunocastration emerges as the preferable alternative to surgical castration, aligning with ecological and animal welfare goals. This review highlights the potential of immunocastration to balance productivity and sustainability in fattening pigs while addressing consumer and regulatory concerns.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"21 ","pages":"Article 100232"},"PeriodicalIF":12.4,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143878868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that all key environmental resources are covered regarding their role for urban planetary health, with climate, food, biota, land, and water identified as the most critical elements for enhancing planetary health. Moreover, the analysed literature shows that despite the many challenges, urban areas offer a multitude of opportunities for societal, political, and economic interventions that can benefit environmental and human health. Maximizing synergies and minimizing trade-offs requires addressing both challenges and opportunities. This often involves making multiple changes at both the urban societal and governance levels.

Specifically, LULC and ecosystem service data were applied to assess carbon storage and habitat quality from 1990 to 2020. LULC projections from 2030 to 2060, incorporating habitat quality constraints, were generated to assess carbon storage and its economic value.

Projections indicate continued growth under the current trend, with 125.19 Tg of carbon sequestration valued at 11.29 billion Chinese Yuan by 2060.
