Ten genetically superior cows were selected under optimum nutritional and sanitary conditions, which were randomized into two study groups (n=5). Data analysis was performed with the T-Student test for paired or related samples in the SAS statistical program. Group 1 received 200mg of FSH in 8 doses (Folltropin-V); group 2 was treated with 140mg of FSH in 4 doses + 400 U.I of eCG single dose (Folltropin-V + Folligon). The variables to be measured were: number of corpus luteum; number of apt embryos to be washable; number of apt embryos to be transferred and embryo quality. No statistically significant difference was found among any of the variables under study (P˃0.05). However, cost-benefit analysis showed that treatment 1 was more cost-effective than treatment 2. Ratio 1: 11.58 versus 1: 7.69 USD respectively. |
