Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.

Quality of Forage Cactus Silage with the Addition of Hay from Forages Adapted to the Semiarid Region

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
This study investigated the effects of including hays from different forages adapted to the semiarid region on the forage cactus (Opuntia fícus‐indica (L.) Mill) silage quality. A completely randomized design, with five treatments was used: pure forage cactus and forage cactus associated with 30% hay from gliricidia (Gliricidia sepium), pornunça ...

Livestock grazing boosts plant diversity in the Greater Serengeti–Mara Ecosystem

Ecological Applications, Volume 36, Issue 2, March 2026.
Abstract Intensifying land use is a global threat to biodiversity, and livestock grazing—occupying 26% of terrestrial land—is one of such threats. Designated protected areas are one of the key conservation strategies to halt biodiversity loss, but their effectiveness is debated, in part because of data shortage at relevant spatial scales (>1 ha).

BREED AND ENVIRONMENTAL EFFECTS ON BIRTH WEIGHT, WEANING WEIGHT AND CALVING INTERVAL OF ZEBU CATTLE IN SOUTHEASTERN MEXICO

Tropical and Subtropical Agroecosystems, 2017
Records of beef cows from a ranch in southern Mexico gave 1967 birth weights (BW), 1587 weaning weights adjusted to 210 days of age (AWW) and 2001 calving intervals (CI) for the comparison of the breed groups: Brahman (BR), Guzerat (GU), Nellore (NE) and

Economic Impact and Disease Insights: Understanding Organ Condemnation in Cattle Slaughtered at Bahir Dar Abattoir

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
From 334 cattle slaughtered in the Bahir Dar municipal abattoir, different lesions resulting in total or partial organ condemnation were found in organs of 12 (3.6%) cattle. Organs affected by different lesions or disease were liver 14.6% (49/334), lung 9.9% (33/334), heart 2.40% (8/334), kidney 3.6% (12/334) and tongue 0.9% (3/334).

Equine trypanosomiasis, a systematic review and meta‐analyses: Prevalence, morbidity and mortality

Equine Veterinary Journal, Volume 58, Issue 2, Page 291-319, March 2026.
Abstract Background Equine trypanosomiasis is a neglected protozoal disease. Objectives To perform a systematic search of literature to explore: (1) In equines what is the global geographical distribution and prevalence of trypanosomiasis? In low and middle‐income countries (LMICs) is trypanosomiasis more prevalent than in higher‐income countries (HICs)
