Hungry for Knowledge: Octopamine Signaling Regulates Hunger‐Enhanced Olfactory Learning

open access: yesAdvanced Science, EarlyView.
Researchers demonstrate that hunger state facilitates both aversive and appetitive olfactory learning. Two distinct octopamine signaling pathways are involved in aversive or appetitive memory formation in the hunger state. And, hunger state also facilitates the formation of both types of memories via an evolutionarily conserved norepinephrine (the ...

Assessment of the genetic diversity of cattle by marker genes of dairy productivity

open access: yesВетеринария и кормление
Absrtact. The paper presents an assessment of the genetic diversity of cattle by the genes of dairy productivity: kappa-casein (CSN3), beta-casein (CSN2), beta-casein A1A2 (CSN2 A1A2) and genes involved in the regulation of milk production: fatty acid ...

Common vetch (Vicia sativa) multi-podded mutants for enhanced commercial seed production

open access: yesТруды по прикладной ботанике, генетике и селекции, 2019
In comparison to other annual forage legumes, such as pea (Pisum sativum L.), advances in breeding vetches (Vicia spp.) are rather modest. One of the main obstacles in increasing the cultivation area under vetches is uncertain seed production, mostly due

Modern and Ancient Genomes Reveal Neolithic Paternal Expansions of Millet and Rice Farmers and Demic Diffusion from China into Mainland Southeast Asia

open access: yesAdvanced Science, EarlyView.
This study clarifies the genetic patterns of paternal lineages across East Asia and Mainland Southeast Asia. Han populations are relatively homogeneous, whereas southern ethnolinguistic minorities display regional structures. Shared Y‐chromosome lineages indicate Neolithic expansions and extensive north‐south gene flow, supporting demic diffusion ...

Ecological stability of broad bean (Vicia faba L.) in organic farming conditions

open access: yesВавиловский журнал генетики и селекции, 2020
The main direction in the breeding of legumes is the development of high-productive cultivars with stable yields. In order to assess the ecological stability of 17 broad bean accessions (Fb 1896, Fb 1903, Fb 1929, Fb 2481, Fb 2486, Fb 3270, BGE 002106 ...

Taro leaf and stylo forage as protein sources for pigs in Laos [PDF]

open access: yes, 2012
Existing forage plants may have applications as alternative protein resources for pigs in smallholder farming systems. This thesis examined the effect of harvesting/defoliation interval on the yield and chemical composition of taro leaves and stylo ...

Dollars for Drops: Abatement Cost of Water for Irrigation in the Colorado River Basin

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The Colorado River is a lifeline for more than 40 million people in the western United States. However, with climate change diminishing snowpacks in the Rocky Mountains and increasing demands from agriculture and urban areas, the river's flow has become insufficient to meet all the competing needs.

Using Winter Rye as Forage in Corn Silage Systems [PDF]

open access: yes, 2017
Producing sufficient high quality forage throughout the year is becoming difficult given current economic and environmental pressures. Farmers are looking for strategies to improve yield and quality of their own forage to reduce the financial burden of ...

Forage Options for Tanzania Southern Highlands: Preliminary Assessment [PDF]

open access: yes, 2020
In adequate quality and quantity, forages curtail animal production in sub-Saharan Africa. As such, the potential of livestock agriculture to contribute to household nutrition and incomes is usually compromised, against an increasing consumption of ...

2023–2027 CAP First Pillar Reform and Livestock Sector: Production and Economic Impacts on Italian Specialized Dairy Cattle Farms

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The present study uses an agroeconomic supply model to assess the impacts of 2023–2027 CAP on Italian specialized dairy cattle farms. The model considers the voluntary choice of Eco‐Scheme 1, specifically addressed to livestock farms, through the implementation of binary variables.
