UtilizaĆ§Ć£o da multimistura durante a lactaĆ§Ć£o e seus efeitos na produĆ§Ć£o e composiĆ§Ć£o do leite materno de ratas Use of multimixture during lactation and its effects on production and composition of rat milk
A multimistura, composta por farelos, pĆ³s de folhas verdes, pĆ³s de sementes e pĆ³ da casca de ovo, vem sendo amplamente recomendada para aumentar a produĆ§Ć£o de leite materno, porĆ©m sem bases cientĆficas que confirmem sua eficĆ”cia. Este estudo objetivou avaliar o desempenho lactacional de ratas alimentadas com dieta suplementada com 2% de multimistura (MM). Foram utilizados ratos fĆŖmeas da linhagem Wistar lactantes com idade entre 90 e 100 dias de vida, divididos nos seguintes grupos (n=12): a) Ć base da dieta habitual do Estado do Rio de Janeiro (HERJ); b) dieta HERJ suplementada com 2% de multimistura (HERJ+MM); c) Ć base de caseĆna, com 12% de proteĆnas (CAS1); d) Ć base de caseĆna, com 20% de proteĆnas (CAS2). Foram determinados os macronutrientes proteĆna, lactose e lipĆdios e a produĆ§Ć£o de leite. O grupo HERJ+MM apresentou a menor produĆ§Ć£o de leite (p<0,05) e o menor conteĆŗdo de lactose, quando comparado com os outros. Portanto, conclui-se que a performance lactacional das ratas cuja raĆ§Ć£o foi suplementada com 2% de multimistura apresentou-se diminuĆda.<br>The addition of multimixture, composed of bran, green leaves powder, seeds powder and eggshell powder, to the population's diet has been encouraged in Brazil, as a means to increase the production of breast milk, although without scientific bases that confirm its efficacy. The objective of this study was to evaluate the lactation performance of rats receiving ad libitum diet supplemented with 2% of multimixture (MM). Female Wistar-lactating rats of 90 to 100 days of age were divided into the following groups (n=12): a) fed the typical diet of the state of Rio de Janeiro, Brazil (HERJ); b) HERJ diet supplemented with 2% of multimixture (HERJ+MM); c) casein diet, with 12% of proteins (CAS1); d) casein diet, with 20% of proteins (CAS2). Lipid, lactose and protein concentrations and milk production were determined. The HERJ+MM group presented significantly lower milk production (p<0.05) and lower lactose content. In conclusion, there was a decrease in the lactation performance of rats which received diet supplemented with 2% of multimixture
