A field study of reproductive performance and productivity of Pelibuey ewes in Southeastern Mexico
Tropical Animal Health and Production, 2013The objective was to evaluate the reproductive performance and productivity of Pelibuey ewes in two flocks in Southeastern Mexico. Animals grazed on irrigated star grass (Cynodon plectostachyus). In flock 1, lambs grazed with their mothers from 7 to 70 days of age (weaning age), whereas in flock 2, they were confined and offered chopped grass, a ...

Phenotype Characterization of Pelibuey Native Lambs Resistant to Haemonchus contortus
Annals of the New York Academy of Sciences, 2008Specific phenotypic traits of the blood‐feeder nematode Haemonchus contortus were characterized on Pelibuey native, cross‐breed sheep in a tropical region of Mexico with background of anthelmintic problems. Data were collected on 4‐month‐old lambs (n= 63) and analyzed weekly in three stages: stage 1 (S1, not infected (0–3 weeks)); S2, first infection ...

Determination of carcass traits in Pelibuey ewes using biometric measurements
Small Ruminant Research, 2017Abstract The objective of this study was to evaluate de relationship between biometric measurements (BM) and carcass traits of 28 Pelibuey ewes. The BM were obtained the day before the slaughter and included height at withers (HW), rib depth (RD), body diagonal length (BDL), body length (BL), pelvic girdle length (PGL), rump depth (RuD), rump height (
