Health traits in current dairy cattle breeding: A review

The review focuses on breeding practices aimed at improving resistance to diseases and health disorders that are associated with better efficiency, welfare longevity of cows. It is commonly known like mastitis, foot claw disorders, metabolic reproductive issues seriously violate dairy cows’ well-being. cause prevailing fertility deterioration has been the intensive selection merely based higher milk production starting after Second World War. Therefore since last decades 20th-century genetic programs have increasingly focused increasing traits using several omics techniques, including genomics. first steps for maintaining goal disease were introduction data collection national levels followed by an elaboration gene evaluation systems. was proved exhibit additive variability exploitable in breeding. For greater indicator used, which strongly genetically correlated traits, heritability, above all, usually easily measurable low cost. Genome-wide association studies identified polymorphisms liability could also be used speeding up efforts. Keywords: cow; clinical mastitis; disease;
