Agriculture has an important demand for energy and emits significant quantities of greenhouse gases (GHG). To minimize the effects generated by livestock activities, from both the energetic and environmental perspectives, there exists the possibility of the use of biogas generated from beef cattle confinement. This productive system allows the reduction of methane emissions from enteric fermentation and from manure through the production of biogas. This has become an option for energy policy by contributing to the offer of energy and the reduction of the demand of agriculture for fossil fuels. With a renewable energy resource, the agricultural sector dependent on non-renewable resources, also reduces its dependence on exhaustible resources, so that a policy aimed at the use of biogas and partial energetic autonomy becomes strategic for the sector. The article analyses biogas production potential from waste throughout the entire beef production chain in more intensive systems (total or partial confinement of beef cattle). These solutions can contribute both to the offer of electric energy to the agricultural sector in the country, increasing its productivity, and to the reduction of greenhouse gases.","PeriodicalId":146210,"journal":{"name":"Bovine Science: Challenges and Advances [Working Title]","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126132197","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}

Nigeria’s cattle population is estimated to be around 18.4 million. The number is far insufficient to meet the country’s demand for meat, milk, and other cow products, let alone contribute to GDP. N’dama and Muturu are both Nigerian breeds that are resistant to trypanosomosis. They are humpless longhorn and humpless shorthorn types of beef cattle. The dairy and beef cow industries’ inadequate adoption of ART is partly to blame for Nigeria’s low cattle output. Sex determination, multiple-ovulation and embryo transfer (MOET), oestrus synchronization, artificial insemination (AI), in vitro fertilization (IVF), cloning, and genetic engineering are all examples of assisted reproductive technologies. It has been reported in humans, rodents and domestic animals, abnormal fetuses, newborns and adult offspring arise from ART. Improper matching of breeding animals mostly leads to overfat calves. This review centers on the applications and potentials of ART in the production of trypanotolerant N’dama and Muturu cattle breeds. Some unorthodox medicines which have proven effective in human reproduction can circumvent the shortfalls in the adoption of ART.","PeriodicalId":146210,"journal":{"name":"Bovine Science: Challenges and Advances [Working Title]","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116268573","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}
