| Morphological traits of the whole udder (circumference, width, height, and length), teats (angle, length and width), udder cistern (teat opening and cistern height), and milk yield were measured over one lactation in a total of 18 ewes (nine Chilota and nine Suffolk Down sheep) belonging to the same experimental flock (Centro Experimental INIA Butalcura, Chiloé, Chile). Analysis of variance showed significant effects for breed, sheep within breed, and stage of lactation. Chilota ewes evidenced greater udder circumference (433 mm), udder length (86 mm), teat opening (96º), and milk yield (947 mL d-1) than Suffolk Down ewes (410 mm, 77 mm, 93º, and 559 mL d-1, respectively). Udder circumference, udder width, udder length, cistern height and teat size... |

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... |
