Improving the Quality of Rooster Sperm during Storage at 4 °C by adding Quercetin in form nano-Liposomes and NLC a Diluting Medium

Recent trends occurring in broiler primary breeding companies are described. The structure and operation of broiler primary breeder companies are described from pedigree elite populations, through great-grandparent and grandparent generations, down to the parent stock. The relatively low value of fertility and hatchability, compared with yield and feed efficiency as selection traits, is assesse...

A study was undertaken to test the effect of 2 commercially available probiotics on the production efficiency of broiler chickens hatched from the same breeder flock at 3 different ages (28, 43, and 57 wk). At each of the 3 breeder flock ages, 1,600 broiler chickens were hatched and randomly allocated to 1 of 4 treatments: 1) no probiotics (control), 2) probiotic 1 administered in the drinking ...

In size-structured groups, conflict over rank, resources or access to breeding opportunities is expected to be greatest among individuals that are similar in size. We tested this general prediction using the cooperatively breeding African cichlid, Neolamprologus pulcher. We predicted that, when size differences between group members were small, we would observe some or all of: increased aggress...

This research was carried out to investigate the effects of various levels of dietary organic selenium supplementation (0, 0.1,  0.2 and  0.3 mg/Kg) on reproductive traits of rooster. Semen was collected using abdominal massage and samples were mixed together. Sperm characteristics including percentage of motile, viable and abnormal sperms were assessed. This experiment was carried out based on...

Background: Frozen-thawed rooster semen is not reliable for use in artificial insemination in commercial stocks. Low density lipoprotein (LDL) has been assessed for effectiveness as a cryoprotectant in the extender to improve the quality of frozen-thawed rooster semen. Although LDL has been evaluated in a few studies in other species for semen cryopreservation, to date, no study has been conduc...

The Effect of Resveratrol Antioxidant in Nano Liposome and NLC Forms Rooster Semen Extender During Storage at 4˚C

The natural polyamines spermine and spermidine, and the diamine putrescine, were extracted from rooster testis cells separated by sedimentation at unit gravity, and from vas-deferens spermatozoa. The ratios spermine/DNA and spermidine/DNA were kept relatively constant throughout spermatogenesis, whereas the ratio putrescine/DNA rose in elongated spermatids. The cellular content of spermine, spe...

The event of Peter’s denials of Christ is a frequent subject of Sunday sermons. The prediction and outplaying of the denials, as recorded in the four Gospels, is a powerful reflection of a condition of our relationship with Christ—that our faith is more vulnerable than we care to admit.1 But a small thorny issue surrounds the Gospel accounts of this event, one that is a nagging distraction to s...

A sensitive, specific, and rapid immunochemical method for the measurement of the synthesis of lipoproteins in rooster liver is described. Incubation of liver slices with [aH]leucine resulted in the incorporation of radioactivity into protein material that could be precipitated from crude extracts by a monospecific antibody directed against the antigen common to plasma very low density and low ...
