The objective of this research was to determine the ingestive behavior, volatile fatty acids,and blood biochemical and hormonal variables of goats consuming a diet with 15% glycerin. Feed efficiency (FE) and rumination (ER) of dry matter intake (DMI) and neutral detergent fiber (NDFI) of dairy goats supplemented with glycerin(0 and 15%)were not influenced by treatments (p >0.05). The specific activities of defecation,urination and drinking had a significant effect (p <0.05) in relation to the treatmentswithglycerin in the diet of dairy goats. The occasional activities (defecation, urinating and drinking water) decreased with the additionof 15% of glycerin in the goats'diet. Lactic acid had a significant effect (p <0.001) with the additionof 15% glycerin. Diets for dairy goats with 15% glycerin did not change the consumption of dry material, neutral detergent fiber,nor did they change the ingestive behavior of these animals. The levels of globulin, protein, albumin/globulin, glucose, cholesterol, urea, triglycerides, cortisol, and T4 variables were significantly influenced (p <0.05) by the additionof glycerin in the diet.(AU)
