12.01.2022 IMPORTANT read for anyone interested in Adaptation in cattle Directional Selection and Local Adaptation in Beef Cattle New DNA research findings from Dr Jared Decker... "My group has posted a new preprint on bioRxiv. You can check it out here: https://doi.org/10.1101/2020.03.11.988121 Warning, it is written for a technical audience, not in cowboy terms. So- what are the take-home messages for farmers and ranchers? We can identify the DNA variants responding to your selection decisions. You tend to select cattle that have better immune systems. Hormone production in the ovaries is under selection in Red Angus. Makes sense based on the breed's focus on fertility. Muscle development is under selection in Gelbvieh. We can identify the DNA variants that lead to cattle adapted to their environment Blood vessel tightening or loosening is under environmental selection. The brain and neuron signaling is an important part of environmental adaptation. We are losing local adaptation in beef cattle. Regarding the last point, we can fix the loss of local adaptation through the use of ecoregion-specific EPDs and EPDs to environmental traits like hair shedding."

08.01.2022 Good news for lotfeeding but how to integrate to grazing systems a challenge

07.01.2022 A close look at the DNA of African breeds reveals the evolution of adaptation genes that underpin successful cattle farming in the harsh environments of Africa. Australia has gained African genes through the introduction of the Africander ( Belmont Red), and the Tuli and the Boran that mainly were used in composite breeding and not as purebreds. Given their adaptation and their fertility and meat quality and the fact they are outcrosses to the Brahman (Indicus)-and Brahman d...erived breeds there is a strong argument for a greater use of these genes in the North. The Senepol breed is said to have derived from an African breed the N'Dama, but genomics suggest that the African content has diminished over time through selection throwing more towards the Red Poll and Creole (Criollo) the adapted taurus breed that reached the Americas with the Spanish conquistadores and is still important in the Caribbean and South America. .

07.01.2022 Gene editing news from Argentina. I think I’m correct that in Australia we cannot introduce new genes into an animal by gene editing but we can knock out a gene. Will we be left behind with these technologies?...Continue reading

06.01.2022 Interesting read (15mins) on the breed composition and breeding habits of US beef production. The concentration of British breeds continues and minor breeds are losing market share. Interesting results on producers’ actions and attitudes and some alerts for breed associations. Shame we don’t have an equivalent survey here...

04.01.2022 Crossbreeding in Brazil’s tropics. Angus semen with Nellore cows. Meat quality improved, age of turnoff reduced.Brazil imports millions of Angus semen straws each year with numbers rising each year. Brazil is the global leader in artificial breeding in their beef herd.
