Morphological characterization of the Pelibuey sheep of Yucatan, Mexico
Three databases or stratums: I. The Secretariat of Agriculture, Cattle, Rural Development, Fishing and Feeding, II. Specialized Local Cattle association of sheep farmers of Mérida and, III. Local Cattle Union of Tízimin was used to characterize morphometrically the Pelibuey sheep breed of the state of Yucatan, Mexico. The sample size and producer were determined within stratum. A total of 369 animals within breed standards, males and females, and over a year of age were selected and classified by stratum and coat color: coffee, white, and pinto. Five phaneroptical and 11 morphostructural characteristics in addition to the body weight were registered by animals. All animals presented coffee eyes, tongue without pigmentation dominates for the coffee (20%) and white (24%) coat colors, whereas for the pinto dominates the pigmented tongue (66%). Black hooves dominate in the coffee coat color individuals (57%), faulty colored hooves in the white (68%), and marbled hooves in the pinto (75%). Wooly (30%) and wattled (2%) individuals were common among coat colors. Differences among stratums of live weight, head length, length of the neck, length of hip, and the longitudinal diameter in males; and neck length, wither height, length of the hip, the width of the hip, and thorax perimeter in the females were not significant (P>0.05). Whereas, hip-width in males and head width in females differed significantly among coat colors (P<0.05). The highest correlations for males (0.92) and females (0.87) were for hip height and wither height. Differences found among stratums are associated with differences in the production system. The minimum variation among coat colors indicates that animals come from a common trunk.
