Influence of MC1R Gene Variants on Coat Color of Indicine Cattle Breeds [PDF]

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Indicine cattle display a broad range of coat colors, representing a relevant and breed‐defining trait required for registration in breeder association. Among the genes involved in pigmentation, MC1R stands out for modulating the synthesis of melanin‐related proteins and remains poorly explored in indicine cattle breeds. Therefore, we aimed to

Anticorps monoclonaux anti-IgGs de zébu. Réactivités comparatives

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1998
En utilisant des anticorps monoclonaux (Amclx) anti-IgGs de zébu, plusieurs sortes d'épitopes ont pu être identifiés : spécifiques du zébu, communs au zébu et au boeuf, au zébu et au mouton ou aux trois espèces.
