Dairy goats are highly susceptible to gestational ketosis. Ketosis is the result of an unbalance between energy supply and requirements. The hypothesis was that by increasing intake and glucose precursors (propionate), the indicators of ketosis will be reduced. Twenty four pregnant Murciano-Granadina goats carrying twins were used to study the effects of feeding a mixture of capsicum (that has been shown to stimulate intake) and eugenol plus cinnemaldehyde (that have been shown to promote propionate production in the rumen) on DM intake, milk production and composition, and blood profile. Goats were controlled from 2 weeks prior to 6 weeks after kidding. During the experiment, goats received a TMR diet (DM of a 60:40 forage:concentrate). Treatments were a control (CTR; no additive) and a mixture of capsicum eugenol and cinnamaldehyde (CEC, Pancosma, Switzerland). Intake and milk production were recorded daily, milk composition determined weekly, and blood samples taken days -10, -7, -3, -2, -1, 0, 1, 2, 3, 5, 7 and 15 around kidding to measure insulin, glucose, non-esterified fatty acids (NEFA), triglycerides and betahydroxy-butyrate (BOHB). Results were analyzed using the PROC MIXED procedure of SAS, differences declared at P < 0.05, and tendencies discussed at P < 0.10. No effects were found on feed intake or milk production, However, milk fat (6.48 vs. 5.84 g/Kg) and milk protein (3.86 vs. 3.69 g/kg) were higher in CEC compared with CTR. Plasma insulin concentration tended (P = 0.05) to be higher (0.49 vs. 0.40 micro g/l), AGNE tended (P = 0.09) to be lower (0.52 vs. 0.62 mmol/l) and BOHB was lower (0.44 vs. 0.53 mmol/l) in the CEC treatment compared with CTR, respectively. Results suggest that the effects of the combination of cinnamaldehyde, eugenol and capsicum on ruminal fermentation increased the supply of glucose and reduced body fat mobilization, reducing the risk of ketosis during the periparturient period.
