| The objective of this study was to evaluate the Brachiaria brizantha cv. Marandu canopy structure maintained at different grazing heights under a continuous stocking rate and with a dietary supplementation strategy for the animals during the rainy season. This study also intended to observe the relationships of these variables with the grazing behaviors of the heifers. The effects of three canopy heights (15, 25 and 35 cm) were evaluated in association with three types of supplements: one mineral and two protein/energy supplements, the first with a high rumen degradable protein and energy and the others with a low ratio. Both the protein/energy supplements were provided at 0.3% of body weight/day. The experimental design was completely randomized, with two... |

| ABSTRACT The objective of this study was to determine effects of the addition of calcium salts of fatty acids (CSFA) to the concentrate on the intake and digestibility of dry matter and nutrients and the grazing behavior of lactating Saanen goats. Five multiparous goats in their third lactation and four primiparous goats were used. The animals were distributed into two Latin square designs, which, for the multiparous goats was 5 × 5, with five treatments (0%, 1.5%, 3.0%, 4.5%, and 6.0% CSFA); and for the primiparous goats was 4 × 4, with four treatments (0%, 1.5%, 3.0%, and 4.5% CSFA). The addition of CSFA to the concentrate of lactating Saanen goats did not influence the time spent grazing, ruminating, or lying for multiparous goats. However, for... |

| ABSTRACT: Adaptative traits (rectal temperature-RT, respiratory rate-RR) and grazing behavior (Grazing, Ruminating and Rest time, and Sun or Shade time) of Bonsmara-Hereford crossbred-BH, n = 15, and purebred Hereford-HH, n = 18, yearling heifers, in a grazing system of Uruguay. Environment characterization was made using THIadjusted by radiation and wind speed (no, mild, and severe heat weaves), and the comprehensive climatic index-CCI (no, middle, moderate and severe stress). Adaptative traits were measured twice a day, weekly, in two consecutive days in summer and winter at 08h00 and 16h00. Grazing behavior was observed from 07h00 to 21h00 each 600 s twice in summer. The records were analyzed using a mixed model. Significant effect of genotype was... |

Inv. Agr. 41(2):249-254. A pilot study was undertaken to determine the pattern of feeding preferences and grazing behavior of the Chilota breed of sheep in the Chiloé Archipelago. First, eight Chilota and eight Suffolk Down ewes were faced with different numbers of plant species (offered only for 10 min), after fasting and after grazing a calafatal, a secondary succession dominated by shrubs. The experiment was repeated four times within a period of 22 d and included a 1-month pre-experimental period. Second, six Chilota and six Suffolk Down ewes, randomly selected... |
