متن کاملCytologic and histologic characteristics of endometritis in postpartum dairy cows
Endometritis is a prevalent uterine infection in postpartum dairy cows that causes some alterations in the endometrium. So, the aim of this study was to determine the comparative cellular and histological characteristics of uterus, especially neutrophils index and cell morphological alterations, in healthy and endometritic Holstein cows. Thirty non-pregnant cows were used. Based on uterine disc...
متن کاملFollicle growth, corpus luteum function and their effects on embryo development in postpartum dairy cows.
Absent or irregular ovarian cycles in lactating dairy cows are caused by failure to ovulate the dominant follicle at the appropriate time. The follicle then either regresses or develops into a cyst. This process can be triggered by a variety of metabolic and disease factors that act at the hypothalamus and pituitary gland to inhibit pulsatile LH secretion and the LH surge, and at the ovary to r...
متن کاملNorgestomet and gonadotropin-releasing hormone enhance corpus luteum function and fertility of postpartum suckled beef cows.
In Exp. 1,101 suckled beef cows were administered two injections of prostaglandin F2 alpha (PGF2 alpha) 11 d apart. Cows in Group 1 received no additional treatment. Cows in Groups 2 and 3 received 250 micrograms of GnRH plus 47-h calf removal. Cows in Group 3 also received a norgestomet ear implant that was inserted 4 d after the first PGF2 alpha injection and left in situ for 8 d. The second ...
متن کاملEndometrial expression of selected transcripts in postpartum of primiparous Holstein cows with clinical and subclinical endometritis.
Postpartum endometritis compromises milk production and fertility in high-producing dairy cows. Infection of the endometrium induces an inflammatory response with secretion of cytokines that lead to polymorphonuclear cells (PMN) influx and bacterial clearance. Considering that only a portion of cows with endometritis is eligible for clinical diagnosis, there is an increasing effort for developi...
