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).

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 ...

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.

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

Sward Height in Grazing Management: Species Adaptation [PDF]

Under continental, northern conditions, yield potential of species such as perennial ryegrass (Loli11111 pere,me L.) and white clover (Trifolium repe,is L.) is considered to be inferior to that of taller, coarser species such as orchardgrass, bromegrass,

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

Structural characteristics of marandu palisadegrass swards subjected to continuous stocking and contrasting rhythms of growth Características estruturais de pastos de capim-marandu submetidos à lotação contínua e ritmos de crescimento contrastantes

Scientia Agricola, 2010
The concept of sward target has been used recently to characterise grazing management practices, but its efficiency to monitor and control sward structure questioned since it corresponds to a single sward structural feature, usually sward surface height.

Effect of sward height during lactation on heifer and calf performance

Proceedings of the New Zealand Grassland Association, 1998
The study compared the performance of Hereford x Friesian heifers and their calves managed on a Low (58±0.5 mm sward height) (L) or High (107±1.4 mm sward height) (H) pasture cover from calf birth up to weaning at about 90 days over spring 1997. Milk production was measured at days 29 and 65 of lactation using the weigh-nurse-weigh technique. At day 29

Effect of sward height on the fermentability coefficient and chemical composition of Guinea grass silage

, 2018
There is a high correlation between sward height and pasture sward structure. Therefore, in tropical grasslands, taking sward height into account has been a much better strategy in rotational stocking management than considering pre-defined days of ...

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 ...
