Genetic Parameter Estimation for Pregnancy Loss and Their Association With Reproductive and Growth Traits in Brahman Cattle Under Extensive Tropical Conditions

open access: yesJournal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 365-374, March 2026.
ABSTRACT This study estimated genetic parameters for pregnancy loss (PL) in Brahman cattle and evaluated the genetic correlation of PL with growth and reproductive traits using both the pedigree relationship matrix (A) and pedigree plus genomic relationship matrix (H). Data were collected from two herds in Bolivia, focusing on three age groups: heifers,

Along the Silenced Footsteps of Latin American Pastoralists: From Mexico to Argentina, a Journey Through Pastoral Systems in Latin America

open access: yesThe Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 1, March 2026.
ABSTRACT Pastoralism worldwide faces a complex landscape of increased pressures and exclusion. Beyond ecological and economic challenges, pastoralists suffer eroding cultural identity, limited generational renewal, and political marginalization. Yet pastoral livelihoods are increasingly recognized as stewards of sustainable futures and amongst the best

Evolutionary History of the Adult β‐Globin Gene in Wild Sheep: First Sequences From the Argali (Ovis ammon) and the Urial (Ovis vignei)

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
This study addresses a key gap in the understanding of molecular adaptation by providing the first complete adult β‐globin gene sequences for two ecologically significant wild sheep species, the Argali (Ovis ammon) and the Urial (Ovis vignei). ABSTRACT The β‐globin gene cluster is a key model for studying molecular adaptation and gene family evolution ...

Body Development, Growth Performance, Ingestive Behavior, and Physiological Responses of Nelore and Crossbred Calves

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
The objective of this study was to evaluate body development, growth performance, ingestive behavior, and physiological responses of Nelore and crossbred calves during the cow‐calf phase. Thirty beef calves were divided into four groups according to their genotype: Nelore (NE; eight animals), Nelore × Senepol (NS; eight animals), Nelore × Montana (NM ...

Características de carcaça de bovinos zebu e cruzados holandês-zebu (F1) nas fases de recria e terminação Carcass characteristics in zebu and crossbred holstein-zebu (F1) steers in the growing and finishing phases

open access: yesRevista Brasileira de Zootecnia, 2004
Foram avaliadas as características de carcaça de bovinos Indubrasil e cruzados F1 Holandês-Gir e F1 Holandês-Guzerá, nas fases de recria e terminação. Foram determinados os rendimentos de carcaça e porcentagens dos cortes básicos, comprimento de carcaça, espessura de gordura subcutânea, área de olho de lombo, proporções de músculo, gordura e ossos.

The use of Diathermic Syncope® for stunning cattle

open access: yesEFSA Journal, Volume 24, Issue 2, February 2026.
Abstract The EFSA Panel on Animal Health and Welfare (AHAW) was asked to deliver a scientific opinion on the use of Diathermic Syncope® (DTS) for stunning cattle. A dossier was provided by the applicant as the basis for an assessment of the extent to which the method is able to provide a level of animal welfare at least equivalent to that ensured by ...
