The effect of prostaglandin F2 alpha during various stages of the oestrous cycle of beef heifers.
The effects of prostaglandin F2\g=a\on peripheral plasma progesterone and oestrogen levels, incidence of oestrous cycle alteration, and fertility were examined in thirty beef heifers. The PGF2\g=a\was administered by insertion of an insemination pipette into the lumen of the uterus during three periods of the oestrous cycle: Days 3 to 5, Days 9 and 10, and Days 16 and 17. Oestrus occurred withi...
متن کاملHistomorphometrical study of the cervix during the oestrous cycle in adult Azarbaijan buffalo
In this study, genital tracts of 20 healthy non-pregnant buffaloes were collected from Urmia abattoir.These genital tracts were selected based on their ovaries conditions, half of them were in follicular phase and the other half were in luteal phase. The samples were taken from anterior, middle and posterior regions of the cervix and fixed in 10% buffer formalin. Then, histological sections of ...
متن کاملUrinary oestrogen levels in the sow during oestrous cycle and early pregnancy.
were characterized by a rise of the levels associated with oestrus to a well-defined peak followed by a sudden decrease, usually to the lowest levels observed. After conception, the levels of oestrone were not appreciably different from those during the oestrous cycle until at the end of the 3rd week at which time the excretion of oestrone increased. The week of maximal oestrone excretion in th...
متن کاملHormone concentrations in the caudal vena cava during the first ovarian follicular wave of the oestrous cycle in heifers.
Changes in pulsatile secretion of LH, FSH, oestradiol and progesterone were related to the growth phase, early plateau phase and regression phase of the first ovarian dominant follicle of the oestrous cycle in Bos indicus heifers. Relationships between these hormones during the three phases were also investigated. Accurate measurements of episodic ovarian steroid secretion were obtained by cath...
متن کاملDifferential gene expression in porcine oviduct during the oestrous cycle.
The oviduct undergoes changes under the influence of steroid hormones during the oestrous cycle. However, the molecular mechanisms underlying oviductal regulation are not fully understood. The aim of the present study was to identify the gene expression profile of the porcine oviduct in different stages of the cycle using microarray technology. A systematic study was performed on animals at fou...
