Expression of miRNAs in Bull Spermatozoa Correlates with Fertility Rates.
Bull spermatozoa are rich in active miRNAs, and it has been shown that specific spermborne miRNAs can be linked to fertility. Thus, expression profiling of spermatozoa could be helpful for understanding male fertility and the ability of spermatozoa to initiate and sustain zygotic, embryonic and foetal development. Herein we hypothesized that bulls with moderate to high fertility can be identifi...
متن کاملO-12: Studies on Sequestration of PDC-109 Protein on Cryodamage and In Vitro Fertility of Crossbred Bull Spermatozoa
Background: Plasma membrane of the spermatozoa interacts with and is altered by abundant seminal PDC-109 present in their immediate milieu in vivo with damaging effect in a time- and concentration- dependent manner. Therefore we hypothesized that sequestration of detrimental protein from ejaculates would be beneficial for cryopreservation of sperm cells. To this aim we evaluated the effect of s...
متن کاملReproductive Characteristics of the Brahman and Brahman Based Bull
GENERAL REPRODUCTIVE TRAITS The Brahman is a Bos indicus breed which was developed in the Gulf Coast states of the United States (Phillips, 1963; Yturria, 1973). The adaptive traits which specifically suit the Brahman and Brahman based breeds for production in temperate, subtropical or tropical areas include: tolerance of internal and external parasites; tolerance of high solar energy, ambient ...
متن کاملAnti-oxidative Effects of Ethanol Extract of Origanum vulgare on Kinetics, Microscopic and Oxidative Parameters of Cryopreserved Holstein Bull Spermatozoa
Origanum vulgare contains high levels of phenolic compounds such as gallic acid and polyphenols such as rosmarinic acid and quercetin. The purpose of this study was to investigate the effects of Origanum vulgare extract, as a natural antioxidant, on freezing-thawing semen quality in Holstein bulls. Three Holstein bulls (5-6 years old, mean live weight 800 kg) were used for semen collection twic...
متن کاملGenetic parameters for growth and carcass traits of Brahman steers.
Spring-born purebred Brahman bull calves (n = 467) with known pedigrees, sired by 68 bulls in 17 private herds in Louisiana, were purchased at weaning from 1996 through 2000 to study variation in growth, carcass, and tenderness traits. After purchase, calves were processed for stocker grazing on ryegrass, fed in a south Texas feedlot, and processed in a commercial facility. Carcass data were re...
