The American Brahmousin Council allows animals that are not purebred to be recorded as percentage animals as long as they are at least one-quarter Limousin and one-quarter Brahman. To be recorded as a purebred Brahmousin, the animal must then be sired by a registered purebred or fullblood Limousin bull, registered Brahman bull, or a registered purebred Brahmousin bull. In Australia, Brahmousin are between one-quarter and three-quarters of the parent breeds with the objective of combining the muscle growth and meat quality of Limousins with the heat and parasite resistance, fast growth, and good mothering ability of the Brahman. Brahmousin is formally recognised as a cattle breed in Australia. Lim-Flex Unlike the Brahmousin, Lim-Flex does not have purebred breed status in any participating countries, which includes the US, Australia, New Zealand, and Canada. The need for the Lim-Flex hybrid arose in 2000 out of a perceived need by North American commercial cattle breeders for hybrid bulls that would assist in achieving end-product targets. Lim-Flex is a registered certification mark awarded to Limousin:Angus crossbred or hybrid cattle in the US with content between 25% and 75% Limousin pedigree blood, and between 25% and 75% of either Angus or Red Angus pedigree blood, with a maximum allowable 1/8th of unknown or other breed. Lim-Flex provide genetic options ranging from high content fullblood and purebred Limousin with high levels of muscle and efficiency, to blended options with higher marbling and maternal characteristics associated with Angus cattle, to meet the needs of crossbreeding programmes. The Lim-Flex certification mark has been adopted in Australia and New Zealand, where "commercial Lim-Flex must be 25 to 75 percent Limousin and 25 to 75 percent Angus or Red Angus", and in Canada, where they "must be 37.5 to 75 percent Limousin and 25 to 62.5 percent Angus or Red Angus, with a maximum allowance of another breed or unknown breed composition of 12.5 percent (1/8th)". Appearance Most Limousin cattle's coloration varies from light wheat to darker golden-red. Other coloration, mainly black, has been developed through cross-breeding and grading up from other breeds of cattle. In addition to altering natural coloration, other traits, such as polled (a genetic lack of horns), have been introduced through crossbreeding. Angus cattle have been the dominant source of black and polled genes now present in graded-up, high-content Limousins found throughout the world. Temperament Since the mid-1990s, Limousin breeders have worked extensively on improving disposition
