Objective: determine the effects of red clover consumption on bloodprofile in dairy cows on the farm Tunguavita of the UPTC. Materials and Methods: 32 animalswith similar characteristics were selected, they were randomly divided into four treatments: T1: 8 cows with red clover supplement accordingto their requirements, T2: 8 cows with extra red clover supplement 25%, T3: 8 cows with extra red clover supplement 50% and T4: no supplement,for 60 days. Before supplementation, at 30- and 60-days post-supplementation, variables suchas estradiol (E2), progesterone (P4), luteinizinghormone (LH), triglycerides, triiodothyronine (T3), thyroxine (T4), insulin, stimulatinghormone were measured the thyroid (TSH),glucose and blood urea nitrogen (BUN).Results:among the groups supplemented with Red Clover, no statistical differences were observed;but in relation to the control group it is evident that the values of estradiol, LH, BUN, TSH and progesterone were lower than (P <0.05); On the other hand, the levels of T3 and T4 showed a similar behavior throughout the experimentand an increase in the values of insulin and triglycerides was observed Conclusions: the supplementation with red clover has a negative effect on the reproductive behavior of dairy cows, presenting lower values in the variables evaluatedesAcceso abiertoUnilasallista Corporación UniversitariaReproducción animalHormonasNutrición animalinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAcces
