In vitro performance of Zebu (Bos indicus) and Taurus (Bos taurus) donor cow embryos [PDF]

open access: yesRevista Brasileira de Saúde e Produção Animal, 2020
ABSTRACT In this study, the in vitro production of bovine embryos from zebu and taurine donors was compared. Cumulus-oocyte complexes (COCs) were obtained from 167 Bos taurus and 161 Bos indicus donors by ovum pick-up. COCs were classified based on their morphological quality, matured in incubators for 22 to 24 h in maturation medium, and then ...

The Polled Locus Maps to BTA1 in a Bos indicus x Bos taurus Cross [PDF]

open access: yesJournal of Heredity, 1996
Two hundred and nine reciprocal backcross and F2 progeny produced by embryo transfer from Angus (Bos taurus) and Brahman (Bos indicus) parents and their 60 parents and grandparents were utilized to localize the locus (POLL) responsible for the polled phenotype in a genetic map of bovine chromosome 1.

Prey restoration facilitates early tiger recolonization in a human‐dominated protected area of Thailand

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Rewilding is an important ecological restoration practice for sustaining ecosystem function. Reintroduction of large‐ and medium‐sized prey can facilitate recolonization by predators such as tigers (Panthera tigris) in fragmented habitats.
