<b>Induced hypothyroidism effect on superovulatory response and diet apparent digestibility in beef cows</b> - DOI: 10.4025/actascianimsci.v28i3.47
Abstract
The experiment aimed to establish the effect of hypothyroidism induced on the ovarian response to the exogenous follicle stimulating hormone, the normality of the cows estrous cycle, and apparent diet digestibility. 10 Nelore cows were used and treated with propylthiouracil (PTU). DM apparent digestibility, average numbers of corpus luteum, collected embryos, unfertilized structures, degenerated structures, morulas, collecting rate, fertilization rate, did not present significant variation (P>0.05). In the treated animals, de average T3, T4, and TSH values were 1.35 ±0.1, 20.95±1.37 and 7.95±0.36, respectively, and in the controls 1.91+0.1 for T3, 61.82+1.37 for T4 and 2.61+0.36 TSH, with significant difference (P<0.05). Based on the results, it is possible to conclude that hypothyroidism did not affect diet apparent digestibility, embryos production, steroidogenesis or ovarian activityDownloads
