The role of melatonin in modulating mammalian reproduction is particular interest; however, its effects on ovarian follicles and their oocytes still remain to be characterized. This study determined the influence treatment follicular growth patterns vitro oocyte developmental competence. In a first experiment, supplementation dynamics were evaluated using daily transrectal ultrasonographies for 21 days, 7 multiparous Sarda goats receiving subcutaneous implant 18 mg 5 control untreated does....

The present study aimed to determine the influence of a glucogenic supply on oocyte developmental competence. Oestrous cycles were synchronised in 22 Sarda ewes by insertion (Day 0) one intravaginal progestagen-impregnated sponge that was removed after 6 days. After removal, randomly allocated into two experimental groups (treated and control ewes) and, from Day 7 11, treated received oral administration mixture, whereas animals water. Follicular development stimulated FSH Days 8 10. Glucose...

Summary This study investigated whether a 22‐day period of undernutrition (half maintenance) could affect maternal endocrine responses and liver gene expression during early pregnancy (day 7). Thirty‐five ewes were fed 1.5 ( n = 15) or 0.5 20) their maintenance requirements slaughtered on day 7 the oestrus cycle (oestrus 0). Insulin, IGF, leptin non‐esterified fatty acids (NEFA) determined days −14, 0 7. Transcripts IGF family adipokines receptors in by real‐time RT‐PCR. Underfed animals...

The current study investigated hormonal and ovarian changes during physiological reproductive aging in Sarda ewes. In a first experiment, follicular corpus luteum dynamics were compared an induced oestrus cycle aged (12–14 years) young adult ewes (4–5 years). Oestrus characteristics did not differ between the two experimental groups. However, function phase showed significant alterations ewes, as determined by lack of dominance effect lower mean values circulating oestradiol (E 2 ) inhibin...

The aim of the present study was to assess whether strategic supplementation bypass LO can enhance reproductive indexes—fertility, lambing rate, and prolificacy—in dairy Sarda ewes at end lactation. To leads adsorptions PUFAs their subsequent utilization by body tissues, milk composition fatty acid content were analyzed. Forty-eight assigned following groups: control group (CT; N = 24), fed with a diet without LO; treatment (LO; supplemented (10.8 g/ewe/day). Both diets had similar crude...

Contents The objective of this study was to assess the efficacy two reduced doses vs a high/luteolytic dose cloprostenol on luteolytic activity and synchronization oestrus in cyclic goats. Experiment 1, included 24 goats randomly allocated three groups: control group (group H) received single high (87.5 μg; 1.0 ml; i.m.) M L groups, which half (43.75 0.5 ml) third (26.25 0.3 highest dose, respectively. 2, assigned same experimental groups. Each treated using injections administered 10 days...

The use of progestagen for 14 days in protocols estrus synchronization has been reported to affect conception rate sheep. We evaluated the effects treatment on growth pattern and follicular function preovulatory follicles (PF) their implication subordinated (SF). Adult female sheep were randomly assigned following groups: 1) FGA (n = 7), which received an intravaginal device fluorogestone acetate sponges (Chronogest®, Intervet International, Boxmeer, Netherlands) days, or 2) PGF 3 i.m....
