Impact of different grazing systems for bovine cattle on the soil microbiological and chemical characteristics

Revista Brasileira de Zootecnia, 2011
The objective of this work was to study the effect of grazing systems: rotational, continuous and the absence of cattle, in pastures of Brachiaria brizantha on microbial activity (respiratory, potential nitrification, solubilizing, and enzymatic) and on ...

Single‐stage orthognathic correction of campylorrhinus lateralis in foals using transection and fixation: Surgical description and outcome of four horses

Equine Veterinary Journal, EarlyView.
Abstract Background Campylorrhinus lateralis (‘wry nose’) is a rare congenital maxillofacial deformity of foals resulting in compromise of the airway and severe class 4 malocclusion. Various surgical techniques to correct the deformity have been described, but contemporary data on single‐stage transection and fixation, including use of a rib graft, and

Evaluación de un sistema de manejo de Axonopus catarinensis en rotación basado en el remanente de forraje no pastado (Renopa)

Tropical Grasslands-Forrajes Tropicales, 2018
A new rotational-grazing management strategy called PUP-grazing (proportion of un-grazed pasture, which is the estimated percentage of pasture vegetation without signs of being consumed) was compared with the traditional rotational-grazing management ...

Effect of equine flysheets on fly avoidance behaviours, body temperature, stress level, and heart rate

Equine Veterinary Journal, EarlyView.
Abstract Background Flysheet use is common without any published scientific evidence to justify their use. Objectives To demonstrate the effectiveness of flysheets at reducing fly avoidance behaviours and measuring changes in body temperature, heart rate, and cortisol levels. Study Design Ten‐week alternating crossover design.

Material design strategies for flexible n‐type polymer semiconductors

FlexMat, EarlyView.
This Perspective surveys recent progress in flexible n‐type polymer semiconductors, emphasizing the interplay between molecular design and microstructure control. It outlines strategies including backbone and side‐chain engineering, multilevel microstructure optimization, to maintain charge‐transport pathways under mechanical deformation.

The nitrogen dilemma: Toward a novel fertilization management framework for reconciling productivity and diversity in grasslands

Grassland Research, EarlyView.
Nitrogen fertilization raises grassland productivity but steadily undermines plant diversity. Instead of applying the same rate everywhere every year, the PRISM framework is designed to rotate high‐ and low‐nitrogen paddocks across the farm over time. This spatiotemporal cycling aims to maintain farm‐scale productivity while creating periodic windows ...

Can Ammonium Nitrate Be a Strategic Tool by Replacing Urea as a Nitrogen Supplementation Source to Beef Cattle in Intensified Grazing Systems?

Fermentation
For cattle raised on tropical grass pastures, it is essential to explore strategies that circumvent climatic seasonality that affect forage availability and quality. We hypothesize that the intensification of grazing systems, with rotational and deferred
