Standardized evaluation of sperm quality is essential for research, commercial-scale cryopreservation, and induced spawning. However, standardized methods for evaluation of sperm bundles (spermatozeugmata or spermatophores) have not been established. The purpose of the present study was to use Redtail Splitfin (Xenotoca eiseni) as a model for fresh...

The aim of this study was to examine the cell apoptosis, gene expression and activity of caspases 2, 3, 8 and 9, and the mRNA expression of selected egg-specific proteins in the chicken oviduct during pause in egg laying induced by tamoxifen (TMX) treatment. The experiment was carried out on Hy-Line Brown laying hens. The control birds were treated...

In prepubertal males, FSH facilitates Sertoli cell proliferation and testis maturation. The study aimed to determine the effect of an exogenous FSH treatment on hormone secretion and testis development in Angus bulls. Bulls (n = 22) weaned at 53 ± 3.8 days of age were randomized into two treatment groups based on age and pedigree. Beginning at Day ...

The use of genomic testing in the cattle industries has renewed an interest in hastening bull puberty. In prepubertal males, FSH facilitates Sertoli cell proliferation and testis maturation. The aim of this study was to determine the effect of prepubertal administration of a timed-release FSH (delivered in a hyaluronan solution) on hormone secretio...

l-carnitine is an antioxidant and β-oxidation stimulator substance commonly used to improve metabolic performance of oocytes and embryos in in vitro systems. However, few studies have evaluated its beneficial effects in embryos produced in vivo. This study aimed to evaluate the effect of l-carnitine supplementation into vitrification or warming sol...

Dairy cow undergoes tremendous physiological challenges during the transition period leading to negative energy balance (NEBAL), impaired immunity and oxidative stress that ultimately compromises the postpartum fertility. Accordingly, we investigated the effects of antioxidant supplementation and increased energy allowance on transition stress and ...

Adiponectin is an adipokine secreted primarily by adipocytes and is involved in the control of male and female reproductive functions. Circulating levels of adiponectin are inversely correlated with body fat mass, and its biological effects are predominantly mediated through two receptors, AdipoR1 and AdipoR2. The aim of the present study was to ve...

The mammalian epididymis provides an appropriate environment for sperm maturation. During the epididymal transit, spermatozoa undergo biochemical and morphological changes that lead to the acquisition of the fertilizing capacity. In this study we analysed the fucosylation status of membrane glycoproteins in the spermatozoa obtained from different r...

The aim of this study was to report prevalences and causes of dystocias in dairy and beef cattle, in primiparous and multiparous cows, as well as the mortality rate of calves and cows, obtained after 11 years of records across various farms in Italy. On a total of 14,575 records from dairy Italian Friesian cows, beef Romagnola and Marchigiana cows,...

The search for non-invasive signs of oocyte meiotic competence is very important for the development of in vitro follicle culture (IVFC) systems. The aims of the present study were: (1) to investigate the effect of in vitro maturation (IVM) of in vivo grown goat COCs, in group or individually, on oocyte chromatin configuration (Experiment 1), and (...
