Abstract | This experiment aimed to evaluate nutrient
intake, total and partial digestibility of dry matter
(DM), organic matter (OM), crude protein (CP),
neutral (NDF) and acid (ADF) detergent fiber and
ruminal parameters, ammonia concentration and
volatile fatty acids, in beef cattle fed palisade
grass (Brachiaria brizantha cv. marandu) at two
regrowth ages, 30 and 60 days, at two times of
year (January and February). The intake of DM,
OM and CP was influenced by forage age of
regrowth with high values for 30 days; this was
influenced by time of year, being observed in
February the higher intake by animals. DM
digestibility average was 60.7 and 59.4% for 30
and 60 days of forage regrowth, respectively,
however, was observed effect of interaction
between regrowth and time of year, the same
comportment was observed for OM, averages
were 63.9 and 63% for respective ages of
regrowth. CP digestibility was higher for 30 days,
70.8%, than for 60 days of regrowth, 57%. The
NDF and ADF digestibilities were influenced by the
interaction between regrowth and time of year;
their average for 60 days of regrowth in January
were respectively 54.8 and 48.5%, being the
lower values and, in February, the higher values:
64.9 and 60.4%. The ruminal average digestibility
was 79.5, 86.2, 99.4 and 96.7% of the total
degradable for DM, OM, NDF and ADF, respectively.
Effects of regrowth and time of year there were
not recorded. Two hours after the morning meal
was observed the ammonia ruminal concentration
peak. The acetate:propionate: butirate ruminal ratio
observed was 74:18:8(%).
O consumo e digestibilidades total e parcial da
matéria seca (MS), matéria orgânica (MO), proteí-
na bruta (PB), fibras em detergente neutro (FDN)
e ácido (FDA) e os parâmetros ruminais nitrogênio
amoniacal e ácidos graxos de cadeia curta foram
avaliados em bovinos de corte alimentados com
Brachiaria brizantha cv. marandu aos 30 e 60 dias
de rebrota em duas épocas do ano (janeiro e
fevereiro). Os consumos de MS, MO e PB foram
influenciados pela idade de rebrota da forrageira
apresentando maiores valores aos 30 dias e
também influenciados pela época do ano, sendo
em fevereiro seu maior consumo pelos animais. A
digestibilidade da MS foi em média 60,7 e 59,4%
aos 30 e 60 dias de rebrota da forrageira, respec-
tivamente, porém, demonstrou efeito de interação
entre a idade de rebrota e a época do ano, mesmo
comportamento observado para MO, com médias
de 63,9 e 63% para as respectivas idades de
rebrota. A digestibilidade da PB foi maior aos 30
dias de rebrota, média de 70,8%, que aos 60 dias,
média de 57%. As digestibilidades da FDN e da
FDA com efeito significativo para a interação entre
a idade de rebrota e a época do ano, apresentaram
aos 60 dias de rebrota na época de janeiro as
menores médias, 54,8 e 48,5%, respectivamente
e em fevereiro as maiores médias, 64,9 e 60,4%.
A digestibilidade ruminal apresentou médias de
79,5, 86,2, 99,4 e 96,7% do total digerível para MS,
MO, FDN e FDA, respectivamente, não sendo
observados efeitos da idade de rebrota nem da
época do ano. Após 2 horas da alimentação foi
observado o pico de concentração de nitrogênio
amoniacal no rúmen. A média da relação
acetato:propionato:butirato observada foi
74:18:8(%). |
