This study was designed to evaluate the seasonal expression of seminal plasma proteins from two bovine breeds adapted to a subtropical climate and their associations with post-thawing sperm and environmental characteristics. Semen samples were obtained three times in summer and three times in winter from four Crioulo Lageano and four Angus bulls. S...

BackgroundEarly maternal separation may have long-lasting physiological effects on different organ systems. Although long-lasting effects of early maternal separation are mostly studied in connection with the development and function of the central nervous system hypothalamic–pituitary–adrenal axis, animal health, behaviour and productivity, there ...

This study aimed to improve the quality of cryopreserved beef bull (Piedmontese) semen by incorporation of relaxin in diluted semen before cryopreservation procedures. Semen samples were collected from 4 proven fertile bulls, using artificial vagina, once per week for 8 consecutive weeks and pooled together then diluted with Bullxcell® extender, an...

In the dairy breeding industry, prediction of bull fertility in artificial insemination (AI) is important for efficient and economically sustainable production. However, it is challenging to identify bulls with superior fertility applying conventional in vitro sperm assays. In the present study, sperm functionality was investigated to identify a mu...

BackgroundMature sperm carry thousands of RNAs, including mRNAs, lncRNAs, tRNAs, rRNAs and sncRNAs, though their functional significance is still a matter of debate. Growing evidence suggests that sperm RNAs, especially sncRNAs, are selectively retained during spermiogenesis or specifically transferred during epididymis maturation, and are thus del...

BackgroundBovine besnoitiosis, caused by the apicomplexan parasite Besnoitia besnoiti, is a chronic and debilitating cattle disease that notably impairs fertility. Acutely infected bulls may develop respiratory signs and orchitis, and sterility has been reported in chronic infections. However, the pathogenesis of acute disease and its impact on rep...

Kisspeptin (KP) is a hypothalamic neuropeptide that stimulates the secretion of gonadotropin releasing hormone. To determine the acute and chronic effects of KP on serum concentrations of luteinizing hormone (LH) and follicle stimulating hormone (FSH), prepubertal bull calves [12 ± 1 (SD) weeks of age; 96.5 ± 14.5 kg BW] were administered one of fo...

Introduction Traumatic injury to upper alveolus may result in apical displacement of the affected tooth/teeth into the underlying alveolar bone. The tooth while being driven into the socket under the upwardly directed impact force usually causes a crushing fracture of the alveolar socket bone. The tooth may also be displaced through the labial plat...

Cell adhesion molecule1 (CADM1) is a member of the immunoglobulin superfamily (IGSF) that has been found in mammalian testis and plays a substantial role in cell-to-cell interaction via either hemophilic (between spermatogenic cells) or heterophilic (between spermatogenic and somatic Sertoli cells) binding. The present study investigated the immuno...

Un grupo de vaquillas (n=22) y vacas (n=19) Brahman descartadas se engordaron a pasto (165 días) con toros tipo cebú (n=20) para comparar sus rasgos en canal, rendimiento carnicero y rasgos de palatabilidad. Toros superaron significativamente a hembras en peso y rendimiento en canal, conformacion, acabado y ojo del lomo. Vaquillas clasificaron mejo...
