Resumo: Over the last decades, the emphasis on the health of dairy cows has changed from an individual to a herd level. In this scenario, the role played by the recording system and its interpretation by veterinarians has gained primordial importance. The records of productive and reproductive performance and of sanitary status from a southern Brazilian dairy cattle herd have been presented and discussed. The period of study was 2000-2009. Mean values per lactation period were 349D 8436M 290F 275P 201SCS (D: days in lactation, M: kg of milk yield, F: kg of fat, P: kg of protein and SCS: somatic cell score in 1000 cells/ml of milk). Major indexes of reproductive efficiency included age at first calving (31 months), services per conception (2.1), intercalving interval (428 days), calving to conception interval (146 days), mean annual rates of parturitions (76.2%), fetal losses (9.8-19.0%), and stillbirths (3.6%), apart of voluntary waiting period (94 days). Main information on sanitary status of the herd was associated with the mean prevalence of common disorders of dairy cattle such as anaplasmosis (29.8%), mastitis (27.8%), digital diseases (26.3%), ovarian cysts (21.3%), placental retention (19.7%), postpartum uterine infections (10.6%), and calf diarrhea (23.7%) and pneumonia (16.8%), among others. In addition, culling reasons (low reproductive performance [56.3%] and udder/mastitis problems [33.6%]), causes of cattle deaths (anaplasmosis [16.4%] and leukosis [11.4]), and the impact of cattle diseases such as tuberculosis, leukosis, and neosporosis on the herd have also been presented and succinctly discussed. Numbers between brackets represent rates accumulated in the 10-year period.

Os registros de eficiência produtiva e reprodutiva, bem como os de ordem sanitária observados em um rebanho bovino leiteiro no Sul do Brasil foram apresentados e discutidos. O período estudado foi 2000-2009. Os dados de produção leiteira média incluíram, por período de lactação de 349 dias, 8436 kg de leite, 290 kg de gordura e 275 kg de proteína, com média de contagem de células somáticas de 201000 células/ml de leite. Idade ao primeiro parto (31 meses), serviços por concepção (2,1), intervalo entre partos (428 dias), intervalo parto-concepção (146 dias), taxas médias anuais de parição (76,2%), perdas fetais (9,8-19%) e natimortos (3,6%), além de período de espera voluntária (94 dias) foram alguns dos índices de desempenho reprodutivo registrados. Informações sanitárias do rebanho incluíram prevalência média de doenças comuns em bovinos leiteiros tais como anaplasmose (29,8%), mastites (27,8%), doenças digitais (26,3%), cistos ovarianos (21,3%), retenção de placenta (19,7%), infecções uterinas (10,6%), diarreia (23,7%) e pneumonia (16,8%) em terneiras, entre outras. Além disso, razões de descartes (baixo desempenho reprodutivo [56,3%], alterações de úbere [33,6%], etc.), causas de morte (anaplasmose [16,4%], leucose [11.4], etc.) e o impacto de doenças de bovinos como tuberculose, leucose e neosporose sobre o rebanho foram também apresentados e sucintamente discutidos.
