Dietary Bordão‐De‐Velho (Samanea tubulosa) Fruit Improves Grazing Beef Cattle Performance

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
Integrated grass‐tree systems have been proposed to address socio‐ecological challenges in tropical cattle production. Bordão‐de‐velho (Samanea tubulosa), a legume tree native to the Amazon, is commonly found in degraded pastures and valued by farmers for its soil, forage, and livestock benefits.

Initial growth of Megathyrsus maximus cv. Massai grass biostimulated with Burkholderia pyrrocinia at different sowing depths

Acta Scientiarum: Animal Sciences
Sowing depth affects both germination and emergence of seeds. Thus, inoculation with Burkholderia pyrrocinia, a biostimulant, may have positive effects on grass establishment. The aim was to evaluate the effects of inoculation with B.

TOLERÂNCIA DE CULTIVARES DE Megathyrsus maximus AO ESTRESSE HÍDRICO

Nativa
O Brasil é um país com grande diversidade edafoclimática, de modo que a pecuária pode estar localizada em regiões sujeitas ao déficit hídrico e alagamento. Diante disso, é importante conhecer a resposta dos cultivares forrageiros a estas condições de estresse hídrico. Sendo assim, objetivou-se com esse trabalho identificar qual a tolerância ao estresse
