SDF‐1 Attenuates Oocyte Quality Decline During Reproductive Aging Through Autophagy‐Enhanced Stress Granule Scavenging

Advanced Science, EarlyView.
SDF‐1 levels decline significantly with maternal aging. Exogenous supplementation restores meiotic spindle morphology, chromosomal alignment, and mitochondrial function while reducing oxidative stress in aged oocytes. Mechanistically, SDF‐1 enhances autophagic activity to clear accumulated stress granules, thereby rescuing fertilization competence and ...

Building a better ewe: lifetime productivity of Polypay sheep at the U.S. Sheep Experiment Station

Frontiers in Animal Science
Ewe longevity is a primary concern for sheep producers, since keeping productive ewes in the flock for as long as possible will help defray their development and carrying costs. Records from the U.S.

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Ex‐Ante Assessment of Farm Resilience to Institutional Shocks: A Modeling Approach

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Using the agent‐based model SWISSland, we simulate farm‐level responses and interactions under two institutional shocks: tariff reductions and direct payment reductions. Using a framework we developed, we assess resilience capacities, resilience attributes, and the provision of private and public goods, following the shock.

The Power of Unity: Collective Action and Smallholder Agricultural Performance in West Africa

Agribusiness, EarlyView.
ABSTRACT We analyze the impact of collective action through farmer‐based organizations (FBOs) on smallholders' farm performance and income inequality in Ghana, Benin, The Gambia, and Mali. We find that FBO membership increases cereal yield in Ghana and The Gambia, legume yield in Mali, ruminant numbers in Benin and The Gambia, and total farm income in ...

SIMPLIFIED ESTIMATION FORMULA OF THE MILK PRODUCTION IN SHEEP

Scientific Papers Animal Science and Biotechnologies, 2023
The paper proposes a simplified formula to estimate the milk production in sheep.  The formula is based on using the polynomial of Hermite interpolation of 0 degree. The result constitutes a control value for the milk production parameter.
