Popis: There is an emerging trend towards appreciating welfare of farm animals in Sri Lanka. A survey was conducted covering 182 farms in Mid-Country, Sri Lanka to identify management-related risk factors that may affect welfare of dairy calves. A total of 217 calves were monitored where majority were Jersey (54.4%) and Friesian (43.9%) crosses. The management-related risk factors identified include, not practicing naval disinfection for new-borns (100%), not using calving pens (100%), absence of calf pen (96.2%), dam-fed colostrum (99.5%), high mortality (28.0%), high prevalence of hock wounds (83.4%) and diseases (80.2%). Concrete/cement was the prominent flooring category (90.1%) which causes unfriendly footing as indicated by hoof damageable (45.6%), slippery (75.8%), and unclean (40.7%) floor conditions. The hoof damageable floors considerably increased hoof temperature (P65 years). Welfare of male calves was satisfied with appropriate weaning age (3.8+1.4 months), concentrate supplement (0.55+0.25 kg), attending to health problems (96.5%) and selling after six months of age (89.6%). However, both female and male calves were under weight for their corresponding age. The findings emphasized that increasing the awareness on appropriate calf management practices is needed for achieving better results in raising calves into well-grown cattle.
