The objective of this study was to determine plasma concentrations of luteinizing hormone (LH), progesterone (P4) and estradiol-17beta (E2) in Mangalica gilts (M), a Hungarian native breed, and compare them with Landrace gilts (L) during the peri- and post-ovulatory periods. The estrous cycle of gilts was synchronised by Regumate feeding, and ovulation was induced with a gonadotropin-releasing hormone (GnRH) agonist. Blood sampling was carried out via indwelling jugular catheters three times a… Expand
Effects of a preovulatory administered depot gonadotrophin-releasing hormone agonist on reproductive hormone levels and pregnancy outcome in gilts.
TLDR
Treatment with a depot GnRHa for synchronisation of ovulation alters pulsatile LH secretion during early pregnancy in pigs, but this alteration seems not to exert an injurious influence on luteal function and, therefore, on embryo and early fetal development. Expand
Comparison of follicular and oocyte development and reproductive hormone secretion during the ovulatory period in Hungarian native breed, Mangalica, and Landrace gilts.
TLDR
Both diminished follicular development and protracted oocyte maturation may be involved in low fecundity in M, and the present findings may explain these reproductive phenomena. Expand
Comparison of luteinizing hormone, leptin and progesterone levels in the systemic circulation (Vena jugularis) and near the ovarian circulation (Vena cava caudalis) during the oestrous cycle in Mangalica and Landrace gilts.
TLDR
In both breeds, episodic P4 secretion was found in the jugular and caval veins, and both sampling site and breed had an influence on P 4 secretion, and consequently the altered LH secretion pattern in the Mangalica may contribute to the lower fecundity of this breed. Expand
Luteinizing hormone release after administration of the gonadotropin-releasing hormone agonist Fertilan (goserelin) for synchronization of ovulation in pigs.
TLDR
Barrows are an appropriate model for determining GnRH doses that can be effective in inducing a preovulatory-like LH surge in females and the generic GnRH agonist Fertilan, at doses of 10 to 20 microg, can stimulate an LH Surge in gilts, with subsequent ovulation. Expand
Superovulatory ovarian response in Mangalica gilts is not influenced by feeding level.
TLDR
The results indicate an influence of the feeding of altered energy on the number of recruitable preovulatory follicles in modern Landrace but not in native Mangalica breed, and the follicular steroid hormone milieu differs between Landrace and MangAlica gilts but not depending on feeding levels. Expand
Study of enteral versus parenteral application of the gonadotropin releasing hormone agonist Gonadorelin[6-D-Phe] (D-Phe6-LHRH) on LH secretion in Goettinger miniature pigs.
TLDR
Enteral application of D-Phe(6)-LHRH induced LH release in a physiological range from the pituitary of female minipigs, and neither an accumulative effect nor a cumulative LH response were found after repeated GnRH application, and in regard to consumer protection and gonadotropin secretion, D-HHRH residues can be excluded from having long-term effects. Expand
Organometric data of the reproductive tract in cycling and early pregnant Hungarian Mangalica pigs
TLDR
The concept that in Mangalica besides diminished ovarian and oocyte development, uterine conditions, especially growth restricted uterine development, may influence the initial process of early pregnancy and can be another reason of lower fecundity is supported. Expand
Reproductive hormonal profile and estrous cycles of gilts fed fermented and enzyme-supplemented cassava peels meal based diets
Fresh cassava peels were collected, fermented for four days and sundried for 3-5 days. It was ground and used to compound maize replaced grower and finisher diets. A group of 27 weaner giltsExpand
Physiological mechanisms of ovarian follicular growth in pigs--a review.
TLDR
There is a significant heterogeneity in the diameter of large follicles in oestrus, however, the number of follicles correlates with thenumber of corpora lutea after ovulation, and the use of ultrasonography may give a closer insight into these phenomena. Expand
Is the Function of the Porcine Sperm Reservoir Restricted to the Ovulatory Period?
TLDR
It can be assumed that the sperm reservoir is active during different phases of the estrus cycle, however, the mid-cycle oviduct environment considerably impairs sperm cell quality. Expand

Effect of human chorionic gonadotropin on preovulatory luteinizing hormone surge and ovarian hormone secretion in gilts.
TLDR
It is demonstrated that injections of ovulatory doses of hCG had three distinct effects on events concomitant with occurrence of estrus in gilts: decreased secretion of E2 immediately after hCG administration, failure to observe a preovulatory LH surge in some treated animals and earlier production of P4 by newly developed corpora lutea.

Comparisons of endocrinology and behavioural events during the periovulatory period in Meishan and large-white hybrid gilts.
TLDR
Differences between the breeds are indicated, particularly in terms of the age of attainment of puberty and the timing of the onset of behavioural oestrus relative to the oestradiol and LH surges. Expand
Plasma luteinizing hormone and progesterone in the adult female pig during the oestrous cycles, late pregnancy and lactation, and after ovariectomy and pentobarbitone treatment.
TLDR
The pattern of plasma LH and progesterone levels during the oestrous cycle, late pregnancy and lactation and after ovariectomy were characterized, and the effect of pentobarbitone treatment was tested. Expand
Endocrine profiles of sows during the oestrous cycle.
TLDR
High reproducibility of the hormone concentrations examined, which showed similar patterns and values in each of the cycles studied, suggests that these hormones have an important physiological role and may affect oestrous behaviour. Expand
Ovarian activity and hormonal patterns in gilts fed allyl trenbolone.
TLDR
Estrus was effectively synchronized in gilts given 15 mg of AT daily, whereas the feeding of 2.5 mg AT daily resulted in an increased incidence of anestrus, and the profile of reproductive hormones and the degree of ovarian activity was established. Expand
Response of the lactating and postweaning sow to gonadotropin releasing hormone (GnRH).
TLDR
LH response to GnRH in the sow seems to be higher during early lactation than at 2 days postweaning, while LH response to gonadotropin releasing hormone analog (LH-RH-A) during the lactation period and post Weaning were investigated. Expand

The timing of oestrus, the concentrations of oestradiol, LH and progesterone, and embryo survival on day 35 of pregnancy in 16 weaned multiparous sows were studied in relation to the moment ofExpand

TLDR
The reversibly blocked pituitary function induced by a potent GnRH antagonist may be a useful tool to study gonadotropin-dependent final follicular growth as well as ovulation in cyclic heifers and the novel non-isotopic ECLIA methods for the determination of FSH and LH provided practical alternatives to other immunoassay types.

Periovulatory endocrinology in high ovulating Meishan sows.
TLDR
It is shown for the first time that the higher ovulation rate in MS is associated with enhanced oestradiol and inhibin secretion with no significant difference in LH or FSH concentrations. Expand
