Abstract

Two experiments were conducted to evaluate the new rooster semen freezing extender which is containing a low level of glycerol and soybean lecithin as an alternative protective agent in the extender. The aim of the first experiment was to evaluate a new extender for freeze-thawing rooster semen...

Abstract

A hypothesis was tested that long-term administration of thyroxine (T4) in broiler breeder hens would affect fertility, sperm penetration rate, and the duration of fertility. Relative abundance of oviductal TGF-β4 and HSP70 mRNA was determined to ascertain whether T4 treatment affected these genes, ...

Abstract

With avian sperm cryopreservation protocols, the most widely used cryoprotectants (CPAs) are the glycerol (GLY; in gradual freezing: in-straw freezing method), and the dimethylacetamide (DMA; in pellets by plunging into liquid nitrogen: in-pellet rapid freezing method). Use of both methods results...

Abstract

The objective of this study was to investigate factors related to hatching ability of Betong chicken. The 30-week-old Betong chicken was divided into 2 groups each of 10 dam and 4 sires with the same age was pooled semen. The sperm number using in artificial insemination were diluted 100 million...

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...

Abstract

The aim of this study was to determine the role of fatty acids for sperm survival in the sperm storage tubules (SSTs) of the hen oviduct. The mucosa tissues of uterovaginal junction (UVJ) of White Leghorn laying hens with or without artificial insemination using semen from Barred Plymouth Rock...

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

When hens are inseminated by different types of roosters, natural elimination of the influence of insemination by a previous rooster may require some time, reducing the breeding activity of the hens. Two separate experiments were conducted to determine the effects of sperm competition between 2...

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

Avian sperm are stored in the sperm storage tubules (SSTs) of the hen oviduct for a prolonged period. However, the precise mechanisms by which sperm are kept alive in the SSTs are still not fully understood. The aim of this study was to determine whether exosomes are secreted by SST cells and play...
