Abstract: A bovine animal or offspring thereof or a bovine cell or gene comprising a modified chromosomal sequence in at least one allele of a gene encoding an Alpha-actinin-3 protein, wherein said modified chromosomal sequence partially or completely impairs the ability of said animal/cell/gene to encode said protein. The bovine retains all previous functionality, but is distinguished by a reduction in the number and cross-sectional area of Type II muscle fibers, and an increase in the proportion of Type I muscle fibers, resulting in improved feedlot efficiency, improved meat quality, and reduced emissions output.
