Additive genetic, non-additive genetic and permanent environmental effects for female reproductive performance in seasonal calving dairy females

Irish Journal of Agricultural and Food Research, 2016
Excellent reproductive performance (i.e. 365-day calving interval) is paramount to herd profit in seasonal-calving dairy systems. Reproductive targets are currently not being achieved in Irish dairy herds.

Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

Limnology and Oceanography: Methods, Volume 24, Issue 7, July 2026.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

Large, rugged and remote: The challenge of wolf–livestock coexistence on federal lands in the American West

People and Nature, Volume 8, Issue 7, Page 2065-2077, July 2026.
Abstract The expansion of grey wolves (Canis lupus) across the western United States, including on public lands used for extensive livestock grazing, requires tools and techniques for reducing wolf–livestock conflict and supporting coexistence. We examined approaches used on forested lands managed by the U.S.

A review of high nature value farming systems in Europe: Biodiversity, ecosystem services, drivers, innovations and future prospects

People and Nature, Volume 8, Issue 7, Page 2049-2064, July 2026.
Abstract Farming systems of high natural and cultural value represent approximately 30% of farmlands in the European Union and are associated with a high species and habitat diversity and/or the presence of species of European conservation concern. This study aims to synthesize the existing knowledge on the assessment of biodiversity and ecosystem ...

Pastoralist views and positions on coexistence with large carnivores. An overview from conflict areas across Europe

People and Nature, Volume 8, Issue 7, Page 2200-2211, July 2026.
Abstract While large carnivore expansion is a conservation success, it increasingly challenges pastoralism. Beyond economic value, pastoralism provides critical biodiversity and sociocultural benefits, recognized by the UN and the EU's ‘High Nature Value farming’ designation.

Status of On‐Farm Artificial Insemination Services and Effectiveness of Oestrus Synchronization in Dairy Cattle Under Small‐Scale Dairy Farming System

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Cross‐sectional survey and retrospective data on the oestrus synchronization were collected and analysed. The predominant mating system practiced by dairy farmers was AI (55.6%), and 73.5% of farmers apply controlled mating. The highest response rate and pregnancy rate were 89.5% and 45.2%, respectively, whereas a birth rate of 9.6%–18.5% was obtained.

Prevalence and Risk Factors of Q Fever in Smallholder Dairy Farms in Kenya

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Serological and molecular screening revealed widespread exposure to Coxiella burnetii in dairy cattle, linked to reproductive and herd management risk factors. Strengthened surveillance and herd‐level biosecurity are critical to reducing Q fever transmission. ABSTRACT Background Q fever is a neglected zoonotic disease of global concern.

Non-genetic Factors Affecting Gestation Lenght and Postpartum Intervals in Gudali Zebu Cattle of the Adamawa Highlands of Cameroon [PDF]

Tropicultura, 2007
The effects of non-genetic factors (sex of calf, calf birth weight, age of cow, season of calving) affecting gestation length (GL) and open days period (OP) in the Ngaoundere Gudali cattle of the Adamawa (Cameroon) was investigated. Mean GL was 293.4 ± 0.
