“…The normal concentration of daily FSH in Bos taurus cows was 4-6 ng/ml (Alvarez et al, 1998). Folicle Stimulating Hormone concentration of cows in the current experiment were 6.92± 6.17 ng/ml (T2) and 3.32± 3.61 ng/ml T3); that was higher than FSH concentration in cows at 8 hours (0.63 ± 0.08 ng/mL) before ovulation and 56 hours (0.34 ± 0.14 ng/mL) after ovulation (Tortorella et al, 2017).…”

This study aimed to solve the reproductive problems in crossbred cows suffering from ovarian hypofunction (HPO). Twenty-four cows were divided into four treatments with six replications, treatment A concentrate feed (control); treatment B: control + premix; treatment C control + two boluses, and treatment D control + four boluses. The experimental period was 42 days (two estrous cycles). The bolus formulation consisted of vitamin A, vitamin D, vitamin E, zinc, Moringa oleifera and alginate powder. Data analysis using oneway ANOVA with a Completely Randomized Design. The results showed that the lowest number of follicular palpations in cows suffered from HPO was 67% compared to 83% premix administration, while all cows given bolus were obtained follicular palpation or cured 100%. The results showed that the follicle diameters of the four treatments were not significant difference, but the results of rectal palpation were almost palpable, except treatment A on day 21 that could not be palpated on the left follicle and no corpus luteum was found, whereas in treatments B, C and D partially luteal phase were found. It was concluded that the best treatment of HPO in cows suffered from HPO was by providing two boluses, and was administered twice a week.
