Abstract

Thermal manipulation during incubation has been shown to improve post hatch performance in poultry. The aim of the present experiment was to evaluate thermal manipulation on semen quality of roosters during hot climatic conditions. Eggs obtained after artificial insemination from Dahlem Red layer...

Abstract

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...

Abstract

The study aimed to evaluate the reproductive traits in poultry breeder with different weight ranges of two semi-heavy lineages. The experimental method was completely randomized design in factorial arrangement (3×2) with two factors: reproductive methods (artificial insemination and natural mating) ...

Abstract

The goal of this study was to evaluate the occurrence of macrophages in rooster semen and to investigate their impact on the spermatozoa quality. Ross 308 breeder males (n=30) with no evidence of genital tract infections were used to determine the concentration of macrophages using fluorescently...

Abstract

Decreased semen quality and fertility rate is a common feature in broiler breeder roosters. This decrease is associated with dysfunction of Sertoli cells and defective spermatogenesis. Guanidinoacetic acid (GAA), as a precursor of creatine, plays an important role in the proper functioning of...

Abstract

This study was conducted to investigate the effect of D-Aspartic acid (D-Asp) on post-thawed sperm quality, fertility and hatchability outcomes in male broiler breeders. Twenty 55-week-old roosters were selected and equally split into four groups (n=5 rooster/group). Different daily D-Asp doses...

Abstract

Chrysin is a bioflavonoid compound found in passion flower, chamomile, propolis and honey at high levels. Post-thawed sperm quality and fertility of Chrysin-fed roosters were assessed in this study. Twenty 40-week-old male broiler breeders were randomly divided into four groups and fed basal diet...

Abstract

The objective of this study was to assess the effect of different diluent type and storage time on the quality of rooster insemination doses in terms of the spermatozoa motility and apoptosis (in vitro) and spermatozoa fertility potential (in vivo). The motility parameters were significantly (P<0.001) higher in the spermatozoa diluted in saline solution than those diluted in avian diluent at each storage time (0.5, 1 and 2 hours). The proportion of apoptotic spermatozoa was significantly (P<0.05) higher in the semen samples diluted in the avian diluent in comparison to the semen samples diluted in the saline solution after 1 hour of storage. The proportion of dead spermatozoa was significantly (P<0.05) higher in avian diluent in comparison to the semen samples diluted in the saline solution after 2 hours of storage. The fertility of spermatozoa diluted in the avian diluent significantly (P<0.01) decreased 1 hour after the ejaculate collection. In conclusion, saline solution maintained better quality of rooster spermatozoa in terms of their motility values and the proportion of apoptotic and dead cells (...

Abstract

To preserve chicken genetic materials like cryopreserved spermatozoa, various kinds of freezing agents like glycerol, dimethylsuloxide, dimethylformamide or dimethylacetamide have been used for rooster semen preparation. Recently, the usage of N-methylacetamide (MA) for Ogye rooster semen...

Abstract

DNA uptake in the post-acrosomal region of the spermatozoa takes place exclusively in immotile spermatozoa that are naturally unable to fertilize eggs. The present study aimed to assess whether passive transmission of non-viral vectors to the surrounding areas of chicken embryos could be an...
