Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

Animal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.

Característica produtiva e estrutural de pastos mistos de aveia e azevém manejados em quatro alturas sob lotação contínua Structural and productive characteristic of oat and ryegrass mixed pastures managed in four intensities with variable stocking rate

Revista Brasileira de Zootecnia, 2010
Monitoraram-se variáveis relacionadas à produção e à estrutura de pastos de aveia-preta (Avena strigosa, Schreb) e azevém (Lolium multiflorum, Lam) manejados em quatro alturas (10, 20, 30 e 40 cm), em pastejo contínuo com lotação variável (put and take).

Intake and behaviour responses by sheep to changes in sward characteristics under rotational grazing

, 1994
A 10-week grazing experiment was conducted on a perennial ryegrass sward with lactating ewes and their twin lambs. Three paddocks were rotationally grazed with rest periods of from 4 to 56 weeks.

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species

Animal Research and One Health, EarlyView.
A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome

Using sward height to manage pastures

, 2018
Abstract - Pastures need to be managed with a proper herbage availability and keeping a proper residual mass when animals are removed from the area. This herbage has direct relation with the grass height and this residual mass is important due to the photosynthetically active leaves and their capacity in intercept the solar radiation, influencing the ...

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Sward Height on the Performance of Cow-Calf Units and Yearling Steers Grazing Cool Season Pasture [PDF]

Performance and grazing time of cow-calf units and yearling steers were determined over four years on naturalized cool season pastures maintained at a sward height of 4-6, 6-8, 8-10, or 10-12 cm.

Características estruturais e produção de leite em pastos de capim-mombaça (Panicum maximum Jacq.) submetidos a diferentes alturas de pastejo Structure and milk production in Mombaça Grass (Panicum maximum Jacq.) swards submitted to different grazing heights

Ciência Rural, 2007
A estrutura do pasto pode ser vista como uma determinante da dinâmica de crescimento, da competição nas comunidades vegetais e também do comportamento ingestivo dos animais em pastejo. Dessa forma, este experimento foi conduzido com o objetivo de avaliar

Effect of Cyclic Heat Exposure on the Growth Performance and Metabolism of Broilers Fed Palm Kernel Meal

Animal Research and One Health, EarlyView.
The aim of our study is to evaluate the interaction between HS and the incorporation of PKM in broiler chicken diets, as well as its effect on growth performance and metabolism. Based on the results obtained, PKM supplementation failed to mitigate the adverse effects of heat stress in broiler chickens. ABSTRACT The aim of this study was to evaluate the
