In these scenarios, cattle vaccination could be an important strategy to control bTB.\u0000 \u0000 In this review, we describe the diversified vaccine development against bTB and identify gaps in current knowledge. We discuss progress made in live attenuated (including BCG), inactivated and subunit vaccines tested in preclinical models and field trials. We also provide an overview of existing knowledge in the correlates and biomarkers of protection after vaccination against bTB, as well as the most recent advances in the understanding of the protective immune response against tuberculosis.\u0000 The similarities between the mechanisms of the immune protection elicited by humans and cattle against TB and bTB, respectively, make any advance in human TB and bTB vaccines mutually beneficial. In accordance with the One Health concept, this mutual benefit is expected to progress in the future.","PeriodicalId":399225,"journal":{"name":"CABI Reviews","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134559328","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}

In their migrations, they dispersed asexually propagated food plants that were first domesticated in Melanesia and exposed them to further selection in diverse insular environments. Later, staple food crops were introduced from South America. In our search for research on genetic resources characterization and breeding conducted between 1950 and 2022, we retrieved 338 references on 13 crop species. All studies were examined, and a review is presented here. Relatively few were on genetic improvement (92 references) compared to those on morphological diversity (246 references). The paradox is that the Pacific is considered a region exposed to the climatic crisis, perhaps more vulnerable than any other region in the world. This paradox is surprising when we consider that most people in the Pacific are growing staple food crops, for household use and/or for local markets, and occasionally for export. In some countries, it involves more than 75% of the population with a considerable contribution to gross domestic product (GDP). Plant breeding has not been considered a priority to mitigate against forthcoming changes in climate, which is likely to be detrimental to crops with a narrow genetic base. We suggest several possible reasons and that conventional plant breeding should be given high priority based on new approaches that include geographical distribution of allelic diversity.","PeriodicalId":399225,"journal":{"name":"CABI Reviews","volume":"33 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123533762","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}

{"title":"The path to climate neutrality for California dairies","authors":"C. McCabe, H. M. mashad, F. Mitloehner","doi":"10.1079/cabireviews.2023.0015","DOIUrl":"https://doi.org/10.1079/cabireviews.2023.0015","url":null,"abstract":"\u0000 \u0000 In recent years, dairy farms have come under scrutiny with pressure to curb their environmental impacts. Since 1950, the California dairy industry has made strides in reducing greenhouse gas (GHG) emissions per kilogram of milk produced. However, total GHG emissions have remained near constant over the past 15 years. Most on-farm dairy production emissions are in the form of methane (CH\u0000 4\u0000 ) emissions produced via enteric fermentation, where CH\u0000 4\u0000 is produced as a byproduct of feed digestion, and manure management. Methane is a powerful but short-lived GHG. Historically, GWP100 has been utilized to describe a GHG emission’s warming impact over a 100-year time span. To better characterize the impact of CH\u0000 4\u0000 on atmospheric warming, a relatively new accounting system named global warming potential star (GWP*) has been proposed to consider the production and degradation of this short-living GHG. Characterizing greenhouse gases by how they warm our atmosphere instead of the number of emissions produced is a better metric for the true impact of the emissions on atmospheric warming.\u0000 \u0000 \u0000 The goal of this research is to use GWP* to analyze the impact of potential GHG emissions scenarios from California dairy and the impact of those scenarios on atmospheric warming. Utilizing GWP* can help discern when an industry or sector has achieved climate neutrality or no annual warming contributions from industry. This paper also investigates the necessary amount of CH\u0000 4\u0000 reduction needed and the time point at which the dairy sector can achieve climate neutrality. The scenarios are business-as-usual (BAU), 40% reduction in manure CH\u0000 4\u0000 emissions (40 MAN) by applying anaerobic digestion and its alternative technologies, and 40 MAN along with a 10.6% reduction in enteric fermentation CH\u0000 4\u0000 emissions via 1/3 of California’s cows fed the feed additive 3-nitrooxypropanol (40 MAN+EF). Under GWP100 in 2030, carbon dioxide equivalents (CO\u0000 2\u0000 e) for the 40 MAN and the 40 MAN + EF scenarios were reduced by 18 and 22%, respectively compared to the BAU. For all three scenarios, the relative warming impact of the industry decreased over time due to constant herd sizes and total annual emissions. By aggressively decreasing CH\u0000 4\u0000 emissions under the 40 MAN and 40 MAN+EF scenarios, there is the possibility for the California dairy industry to reach climate neutrality by the year 2027. These scenarios have more CH\u0000 4\u0000 naturally removed in the atmosphere than is emitted, thus lowering atmospheric contributions from the industry. These scenarios could be adopted by dairies in other states and countries to help the global dairy industry to achieve climate goals through persistent CH\u0000 4\u0000 mitigation.\u0000","PeriodicalId":399225,"journal":{"name":"CABI Reviews","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122580909","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}

The Farm Bill was last reauthorized by the Agricultural Improvement Act of 2018, but the years since that time have featured four programs that made direct payments to farmers but were not authorized by Congress in the Farm Bill, commonly referred to as ad hoc assistance. In addition, the 117th Congress (2021–2022) enacted the Inflation Reduction Act which invested an additional US$18 billion into farm conservation programs over multiple years.

These rules stipulate that at the time of neck cutting and exsanguination, animals must be alive. As a result, many practicing Muslims do not accept pre-slaughter stunning because they believe it can result in the death of animals before bleeding. Those who accept stunning insist that it must be none-lethal, electrical head-only stunning is the only method that has been scientifically validated to be fully reversible (non-lethal). Due to its full reversibility, electrical head-only stunning is widely used and accepted for the halal slaughter of small ruminants (i.e., sheep and goats), however, it is not widely approved for the slaughter of cattle. This is due to the size of cattle and the bone structure of their heads, electrical head-only stunning in cattle induces a relatively short duration of unconsciousness which presents a risk of cattle recovering during the period they are bled out. Animals will experience the pain of the neck cut if they recover from consciousness during bleeding (due to the short duration of unconsciousness). Due to this animal welfare concern, most cattle are stunned with a penetrative captive bolt, this is, however, not fully reversible, hence many Muslims do not recognise it as a halal-compliant method of stunning.\u0000 Opponents of halal stunning hold a belief that all forms of stunning are inconsistent with the rules of halal meat production, while proponents interpret the rules to mean that stunning is permissible for halal slaughter on condition that animals remain alive prior to neck cutting and bleeding. This paper considers the main methods of stunning used for cattle and discusses the lack of acceptability of some methods of stunning and how this hinders the growth of the halal beef market. The paper further discusses ongoing research into developing animal welfare-friendly and halal compatible beef stunning methods.","PeriodicalId":399225,"journal":{"name":"CABI Reviews","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129987196","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}
