Abstract

Artificial insemination is used in almost 95% of turkey reproductive flocks and is becoming more important in chickens, particularly broiler breeders, as well as in assisted reproduction of wild birds kept in breeding centers. Diluted semen is recommended for artificial insemination. Pooled semen...

Abstract

The techniques of artificial insemination (Al) have been developed on the basis of the studies on the species-related features of reproduction. The efficiency of Al in poultry depends on dose of sperm; sperm quality; motility and inseminating activity of spermatozoa; preservation of the spermatozoa ...

Abstract

The purpose of this study was to evaluate the effects of dietary n-3:n-6 fatty acid (FA) ratios and vitamin E (vitE) on the semen quality, FA composition, hormonal responses, and reproductive performance of aged roosters. Thirty-six Ross broiler breeder roosters were assigned to a 3×2 factorial...

Abstract

The ability to produce viable progeny is a complex trait, involving both male and female components. In poultry, mating ratios are usually 1 male to 6 to 12 females. Consequently, the impact of male reproductive failure is much greater than that for a female. In this study, the genetic...

Abstract

Over the past decades, scientists endeavored to comprehend oxidative stress in poultry spermatozoa and its relationship with fertilizing ability, lipid peroxidation (LPO), free-radical scavenging systems, and antioxidant therapy. Although considerable progress has been made, further improvement is...

Abstract

This study was designed to evaluate orally administrated Letrozole (Lz) on reproductive performance, plasma testosterone and estradiol concentrations and relative abundance of mRNA of GnRH, FSH and LH in roosters. Ross 308 roosters (n=32) that were 40-weeks of age were individually housed and...

Abstract

In poultry breeding the selection of males for reproduction is of great importance, and they should be routinely monitored in order to regularly evaluate their reproductive capacity. Introducing additional methods to the evaluation may be an important aspect in diagnostics of the semen of male...

Abstract

Biweekly determinations were made of semen volume, semen concentration and sperm motility for each of 47 individually caged Peel's Cornish male fowls from 39 to 63 wk of age. Young birds of 3 strains (1 White Rock and 2 dwarf) and force-moulted birds of 3 strains (2 White Rock and 1 dwarf) were...
