Ovarian response of collared peccaries (Pecari tajacu), after hormonal stimulation with gonadotropin association (eCG/hCG), was accessed by both gene expression and follicular development. Thus, collared peccaries (n = 8) were treated with the dose used for sows (swine dose, SWD) or with dose adjusted for peccary's weight (allometric dose, ALD). The gene expression of receptors was evaluated for both gonadotropins (FSHR and LHCGR) and growth factors (proteins codified by TGFβR‐1, BMPR1‐A and BMPR2 genes) in antral follicles, cortex and corpora haemorrhagica (CH). Five days after gonadotropin injection, all females presented CH. The ovulation rate was similar (p > .05) between SWD (4.00 ± 1.17) and ALD (2.50 ± 0.43) group. The total number of follicles per animal and amounts of small (<3 mm), medium (3–5 mm) and large (>5 mm) follicles was similar among groups. However, SWD produced large follicles heavier than ALD group, as accessed by weight of follicular wall biopsies. Ovarian follicles expressed both gonadotropin and growth factor receptors at levels which are independent from gonadotropin dose. In conclusion, the two gonadotropin doses (SWD and ALD) can be used for ovarian stimulation of collared peccary. Additionally, FSH and growth factors (TGFβR‐1, BMPR1‐A and BMPR2) receptors are more expressed in the early follicle development, while LH receptor seems to be more important in the final of follicular growth.

接受促性腺激素刺激方案的领兽（Pecari tajacu Linnaeus，1758）中的卵巢基因表达

基因表达和卵泡发育都可以通过促性腺激素联合激素（eCG / hCG）刺激雄性领领卵巢（Pecari tajacu）的卵巢反应。因此， 用母猪使用的剂量（猪剂量，SWD）或根据猪体重调整的剂量（异体剂量，ALD）处理领兽（n = 8）。评估了促性腺激素（FSHR和LHCGR）和生长因子（由TGFβR-1，BMPR1-A和BMPR2编码的蛋白质）受体的基因表达。基因）在卵泡，皮质和子宫出血（CH）中。促性腺激素注射后五天，所有雌性均出现CH。排卵率相似（p SWD（4.00±1.17）和ALD（2.50±0.43）组之间>> .05）。各组中每个动物的卵泡总数以及小（<3 mm），中（3–5 mm）和大（> 5 mm）卵泡的数量相似。然而，通过滤泡壁活检的重量，SWD产生的卵泡比ALD组重。卵巢卵泡表达促性腺激素和生长因子受体的水平与促性腺激素的剂量无关。总之，两种促性腺激素剂量（SWD和ALD）可用于卵巢刺激领兽的胸腔。此外，FSH和生长因子（TGFβR-1，BMPR1-A和BMPR2）受体在卵泡发育早期表达更多，而LH受体似乎在卵泡生长的最终阶段更重要。
