Canopy structure and foraging behavior associated with phenological stages of winter forage

Journal of Applied Animal Research, 2019
Data from eight experiments were jointly analysed to characterize the ingestive behavior, displacement patterns, use of feeding stations and the dynamics of meals of beef heifers in different phenological stages of winter forages.

Efeito de níveis de suplementação sobre o comportamento ingestivo de bezerras em pastagem de aveia (Avena strigosa Schreb.) e azevém (Lolium multiflorum Lam.) Ingestive behavior of beef heifers grazing oat (Avena strigosa Schreb) and ryegrass (Lolium multiflorum Lam) pasture under supplementation levels

Revista Brasileira de Zootecnia, 2005
Foi avaliado o comportamento ingestivo de bezerras de corte submetidas a diferentes níveis de suplementação energética. Os níveis testados foram (0; 0,5; 1,0; 1,5% do peso vivo), em pastagem de aveia preta (Avena strigosa Schreb.) e azevém (Lolium ...

Ground‐State Charge‐Transfer Doping in Donor–Acceptor Semiconducting Polymers

Advanced Functional Materials, EarlyView.
This work demonstrates controlled ground‐state charge‐transfer complex formation (GS‐CTC) and doping in a series of diketopyrrolopyrrole‐based donor–acceptor semiconducting polymers paired with a π‐conjugated penta‐t‐butylpentacyanopentabenzo[25]annulene “cyanostar” macrocycle. Complementary experimental techniques show how subtle molecular, electronic,

Operational strategies for optimizing grazing when using automatic milking systems in organic dairy production [PDF]

, 2013
Successful grazing when using AMS is possible without having to devote a great deal of time to organize and fetch cows every day. However, a careful strategy and good infrastructure, and observation of cow behaviour and pasture are necessary, and the ...

Structure‐Guided Balancing of Ambipolar Transport Enables Symmetric Switching in Heterojunction Bilayer Organic Transistor Inverters

Advanced Functional Materials, EarlyView.
Balancing the spatially separated p‐ and n‐type transport pathways in heterojunction‐bilayer OTFTs enables symmetric inverter switching (VM ≈ 0.5VDD), whereas discrete integration of unipolar OTFTs gives polarity‐dependent and resistive responses. ABSTRACT High inverter performance in ambipolar organic electronics requires balanced channel strengths ...

Nutrient Intake of Cattle on Rotational and Continuous Grazing Treatments [PDF]

Journal of Range Management, 1991
Many benefits have been obtained from rotational grazing, including management flexibility and livestock distribution, but long-term positive effects on plant and animal production have been inconsistent. The purpose of this cast study was to investigate nutrient intake of animals in 2 production scale grazing, treatments.

Urine patch distribution under dairy grazing at three stocking rates in Ireland [PDF]

, 2011
peer-reviewedNitrate pollution of water is a serious global environmental issue. Grassland agriculture is a major source of diffuse nitrate pollution, with much of this nitrate originating from the urine patches of grazing animals.

Biomass flow and defoliation pattern in alexandergrass fertilized with nitrogen

Bioscience Journal, 2017
The determination of biomass flows can assist on improving pasture fertilization techniques, contributing to identify the best management methods and, in relation the use of fertilizers. Nitrogen deficiency in pastures can reduce forage production.
