    The objective of this work was to evaluate the effects of the dietary inclusion of calcium anacardate on the performance, diarrhea incidence, blood parameters, intestinal morphometry, and pH of gastrointestinal contents in piglets from 21 to 42 days of age. Sixty weaned Topigs piglets, with initial weight of 6.049±0.311 kg, were distributed in the following treatments: diet with or without antibiotic growth promoter (zinc bacitracin) and diets supplemented with increasing levels of calcium anacardate (0.4, 0.8, and 1.2%), with six replicates and two animals per experimental unit. No differences in performance (21 to 42 days of age), blood parameters, and villus height:crypt depth ratio were found between piglets fed diets containing calcium anacardate or antibiotic growth promoter. The replacement of the antibiotic growth promoter zinc bacitracin by calcium anacardate results in similar performance in piglets from 21 to 42 days of age, without changes in blood parameters and in the villus height:crypt depth ratio. The dietary inclusion of calcium anacardate does not decrease diarrhea incidence compared with the antibiotic zinc bacitracin.O objetivo deste trabalho foi avaliar os efeitos da inclusão do anacardato de cálcio em rações para leitões, dos 21 aos 42 dias de idade, sobre desempenho, ocorrência de diarreia, parâmetros sanguíneos, morfometria intestinal e pH dos conteúdos gastrintestinais. Foram avaliados 60 leitões desmamados da linhagem comercial Topigs, com peso inicial de 6,049±0,311 kg, distribuídos entre os seguintes tratamentos: rações com ou sem antibiótico promotor de crescimento (bacitracina de zinco) e rações contendo doses crescentes de anacardato de cálcio (0,4, 0,8 e 1,2%), com seis repetições e dois animais por unidade experimental. Não foram observadas diferenças no desempenho (21 a 42 dias de idade), nos parâmetros sanguíneos e na relação altura de vilosidade/profundidade de cripta entre leitões que receberam ração contendo anacardato de cálcio ou antibiótico promotor de crescimento. A substituição de antibiótico promotor de crescimento bacitracina de zinco pelo anacardato de cálcio resulta em desempenho semelhante de leitões dos 21 aos 42 dias de idade, e não altera os parâmetros sanguíneos e a relação altura de vilosidade/profundidade de cripta. A inclusão de anacardato de cálcio na ração não diminui a ocorrência de diarreia em comparação ao antibiótico bacitracina de zinco
