Genetic evidence of subaortic stenosis in the Newfoundland dog.

Subaortic stenosis (SAS) is a cardiac disorder with a narrowing of the descending aorta below the left ventricular outflow tract of the heart. It occurs in several species and breeds. The Newfoundland is one of the dog breeds where it is more common and usually leads to death at early adulthood.

Optimum allocation of conservation funds and choice of conservation programs for a set of African cattle breeds.

Although funds for livestock conservation are limited there is little known about the optimal allocation of conservation funds. A new algorithm was used to allocate Mio US dollar 1, 2, 3, 5 or unlimited funds, discounted over 50 years, on 23 African cattle breeds conserved with four different possible conservation programs. Additionally, Mio US dollar 1 was preferably allocated to breeds with special traits.

Conservation programmes for African cattle: design, cost and benefits.

Information on costs and benefits of conservation programmes for cattle is scarce in the literature and mainly available for Europe. This study aims at simulating cost of and benefits from different kinds of conservation programmes designed for indigenous African cattle. The programmes include installation of a herdbook and activities to promote the breed (HB), in situ conservation with a sire rotation scheme (IS), cryoconservation of semen (CC) and CC combined with in situ conservation (IC).
