Simulação dos efeitos de fatores dietéticos sobre a população de protozoários ruminais. RESUMO - Objetivou-se desenvolver modelos estatísticos que possam estimar as variações da população de protozoários ruminais mediante alterações na dieta, por meio de utilização dos parâmetros: teores... ...

Protozoários ciliados (Protista, Ciliophora) do rúmen de vacas Holândes x Zebu em lactação alimentadas com dietas à base de cana de açúcar, suplementadas com níveis crescentes da mistura uréia: sulfato de amônio. O experimento teve como objetivo avaliar o efeito de níveis crescentes da mistura uréia:sulfato de amônio 9:1 (0; 0,5; e 1,0% na matéria natural) em dietas à base de cana-de-açúcar (50%, base matéria... ...

Suplementação com óleo de girassol em dietas à base de cana-de-açúcar e seus efeitos sobre as populações de protozoários ciliados no rúmen de vacas lactantes. Repository: BDPA Publication year: 2011
The structure of microbial populations in Nelore GIT reveals inter-dependency of methanogens in feces and rumen. The success of different species of ruminants in the colonization of a diverse range of environments is due to their ability to digest and absorb nutrients from cellulose, a complex polysaccharide fou... ...

Effect of pre-weaning diet on the ruminal archaeal, bacterial, and fungal communities of dairy calves. At birth, calves display an underdeveloped rumen that eventually matures into a fully functional rumen as a result of solid food intake and microbial activity. However, little is known regarding the g... ... Repository: BDPA Publication year: 2017
Taxonomic and predicted functional signatures reveal linkages between the rumen microbiota and feed efficiency in dairy cattle raised in tropical areas. Ruminants digest plant biomass more efficiently than monogastric animals due to their symbiotic relationship with a complex microbiota residing in the rumen environment. What remains unclear is the re... ... Repository: BDPA Publication year: 2022
In vitro activity of different antimicrobials on amino acid deamination in ruminal fluid from dairy cows fed corn silage or corn silage/concentrate diets. For many decades, antimicrobials have been used in livestock diets as growth-promoting agents (Berchielli, 2011). Monensin, an ionophore antibiotic frequently fed to cattle herds, has shown activity a... ... Repository: BDPA Publication year: 2015
Isolamento e análise do perfil xilanolítico de fungos de solo do mangue da Sapiranga. Repository: BDPA Publication year: 2009
Ruminant hologenome characterization of microorganism populations in ruminants digestive tract and their impact on the host s functional genome, performance, product quality and environmental impact. The Hologenome is an evolutionary concept where both the host and its associated microorganisms (microbiota) form a cohesive biological entity known as holobiont, whose interaction a!ects the developm... ...
