That means we can expect (Sayaguesa x Watussi) x (Sayaguesa x Chianina) individuals for next year. I am extremely looking forward to this combination. It might be the most promising combination of the project as it has the potential to unite all needed traits in the right quantity. It will have many Sayaguesa genes, and with Chianina size and Watussi horn size genes this cross product would look almost ideal. That requires luck of course, it could also be that the small horns of Chianina and small body size of Watussi get passed on, most individuals might have a phenotype somewhere in between. That's why I hope that Alvarez will stay with the cows for more than one year. I think that producing at least two good individuals of this combination that can be bred to each other would be a major step forward for the project.

Hi! I have been doing a lot of research on de-extinction and stumbled upon your blog. I just wanted to say that it offers information and insight on the subject not available anywhere else on the internet, the amount of hands-on information and interesting opinions is just amazing, thank you for your work. I'm sorry if it has been asked before, but I was just wondering what is your background, are you a biologist? Also, how do you get so much of your information, are you affiliated with any of the back-breeding programs?
ReplyDeleteIt will be interesting to see what direction the horns will grow in. At the moment they look promising.
ReplyDeleteThe Sanga cattle should be looked at more closely. It may be ascertained that the African cattle in general have a strong admixture of Bos Taurus Africanus of different races. Northern African herdsmen deliberately crossed in wild Auerochsen of different races in the Sahara over a long time. Thus they successfully introduced certain resistances and adaptations into their domestic cattle of near eastern origin. This influence is substantial and accounts for the great genetic variation and distinctness of African cattle both from the European and the Indian breeds. The Sanga cattle are thus not only defined by their Zebu admixture, but by African Auerochsen. this explains some features, like their distinct long horns, lyra shaped in some, as depicted in ancient Egyptian murals or preserved in White Fulani and even Afrikaner cattle.
ReplyDeleteThis complex field has been well researcher here:

Bruford, Pablo Orozco‐ter Wengel, “Domestication of cattle: Two or three events?”, in: Evolutionary Applications – Special edition, 28th June, 2018 published by John Wiley & Sons Ltd. https://doi.org/10.1111/eva.12674

The inter-relation between cultural history and the development of cattle in northern Africa is well researched here:

The inclusion of Sanga cattle like the Watussi is certainly justified not only for pragmatic reasons, such as attaining larger horns, but also for reasons of descent, as they have preserved African Auerochsen heritage.
