Abstract

We evaluated the influence of the substitution of soybean meal (SM) by detoxified castor cake (DCC) on the function hepatic and renal of goats fed with diets containing DCC by alkaline solutions in confinement regime during different stages of biological development (growth, pregnancy and lactation). The treatments consisted of three diets, a formulated with corn and soybean meal (SM) and the others were formulated with detoxified castor cake by calcium hydroxide (Ca(OH)2 DCC) and another composed by detoxified castor by DCC of sodium hydroxide (NaOH). In relation to renal and hepatic parameters showed that there was interaction between the diets and biological stages on the levels of total proteins, direct bilirubin, albumin, alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase. In a general way, the goats fed with both castor cake, regardless of the stage evaluated had higher levels. The detoxified castor cake by alkaline solutions in replacement of soybean meal proved to be a viable alternative in the feeding of goats in the three-stage biological, because it does not affect the functionality of the liver and kidney function.
