Comportamento ingestivo de novilhas leiteiras de três grupos raciais obtidos com dispositivos automáticos
<p>This
study aimed to evaluate the feeding
behavior of 24 heifers divided into three genetic groups (Holstein, ½ Gyr x ½ Holstein
and Gyr), housed in free stall barn fitted with electronic feed bins and water
troughs (INTERGADO<sup>®</sup>) during 30 days. The diet forage: concentrate
ratio was set to 82:18 (DM basis). No difference (p>0.05) was observed among
the treatments for metabolic body weight (BW<sup>0.75</sup>), DM intake related
to BW<sup>0.75</sup>, number of feed bins total visits without intake (FBTVWI),
number of visited feeders (VF), total time in feeder (TTF), water intake (WaI)
and WaI related to BW, BW<sup>0.75</sup> and DM, number of water trough total visits
(WTTV), number of water trough total visits with intake (WTTVI), number of
water troughs visited (WTV) and effective water intake time (EWIT). Difference
was observed (P≤0.05) among the treatments for BW, DMI, number of feed bins
total visits (FBTV), number of feed bins visits with intake (FBTVI), effective feed
intake time (EFIT) and dry matter intake rate (DMIR). The dry matter and water
intakes did not suffer influence from genetic groups when related to BW<sup>0.75</sup>.
The Gyr breed heifers presented higher numbers of feed bins total visits (FBTV)
and feed bins visits with intake (FBTVI) and lower dry matter intake rate (DMIR)
compared to the other groups. </p>

Electrophoretic profile of 16S rRNA gene sequence of rumen archaea from dairy cows fed sugarcane-based diets containing different concentrations of Tithonia diversifolia.
<p>The profiles were obtained after nested-PCR amplification of genomic DNA extracted from ruminal fluid. The UPGMA dendrogram was generated using BioNumerics 7.5.</p
