Niacin alters the ruminal microbial composition of cattle under high-concentrate condition

Animal Nutrition, 2017
To understand the effects of niacin on the ruminal microbial ecology of cattle under high-concentrate diet condition, Illumina MiSeq sequencing technology was used. Three cattle with rumen cannula were used in a 3 × 3 Latin-square design trial.

Ruminal pH Dynamics and Milk Production Response to Concentrate Supplementation in Pasture-Based Dairy Cows [PDF]

Animals
The risk of subacute ruminal acidosis (SARA) in grazing dairy cows remains uncertain, particularly when concentrates are supplemented. This study evaluated the effects of concentrate supplementation on the evolution of diurnal ruminal pH and its ...

Association between Ruminal pH and Rumen Fatty Acids Concentrations of Holstein Cows during the First Half of Lactation

Ruminants, 2022
Ruminal pH in dairy cows follows a diurnal fluctuation; low values are indicative of subacute ruminal acidosis and are associated with alterations of rumen fatty acids concentrations.

Níveis de uréia na ração de novilhos de quatro grupos genéticos: parâmetros ruminais, uréia plasmática e excreções de uréia e creatinina Urea levels in diet for steers of four genetic groups: ruminal parameters, plasma urea, urea and creatinine excretions

Revista Brasileira de Zootecnia, 2008
Objetivou-se avaliar o efeito de quatro níveis de uréia na ração (0; 0,65; 1,3 e 1,95% na matéria seca - MS) sobre pH e amônia ruminais, concentração plasmática de uréia, excreção fracional de uréia e excreções de uréia e creatinina, bem como avaliar as ...

Características ruminais e eficiência de síntese microbiana em novilhos alimentados com cama de frango e suplemento à base de microbiota ruminal liofilizada Ruminal characteristics and microbial synthesis in steers fed broiler litter and supplement based on lyophilized ruminal microbiota

Revista Brasileira de Zootecnia, 1999
O experimento foi realizado para avaliar o efeito de dois níveis de cama de frango (15,0 e 30,0%), associada ou não a um suplemento à base de microbiota ruminal liofilizada de bovinos adultos (0 e 10 g/anim.dia), na alimentação de novilhos Holandês/Zebu.
