Abstract The hormone melatonin (5-methoxy-N-acetyltryptamine) is synthesized primarily in
the pineal gland and retina, and in several peripheral tissues and organs. In the circulation …

Contents Maintenance of high levels of realized fertility (defined as the percentage of ewes
that lamb) and appropriate levels of fecundity are critical for efficient sheep production. The …

Melatonin is a multifunctional molecule that mediates several circadian and seasonal
reproductive processes. The exact role of melatonin in modulating reproduction, however, is …

Melatonin is a multifunctional molecule that mediates several circadian and seasonal
processes in animal reproduction. Melatonin and its metabolites are antioxidants and free …

We have developed a panel of 152 whole-genome radiation hybrids by fusing irradiated
diploid pig lymphocytes or fibroblasts with recipient hamster permanent cells. The number …

To determine whether a link exists between reproductive seasonality and the structure of the
gene for melatonin receptor Mel1a, the latter was studied in two groups of Mérinos d'Arles …

Melatonin (N-acetyl-5-methoxy-tryptamine), a principal product of the pineal gland, is
produced mainly during the dark phase of the circadian cycle. This hormone plays a crucial …

The aim was to study the polymorphisms of the melatonin receptor 1A gene (MTNR1A) and
its relationship with seasonal reproduction in the Sarda sheep breed. Four-thousand …

A white belt is a common coat color phenotype in pigs and is determined by a dominant
allele (Be). Here we present the result of a genome scan performed using a Hampshire …

The aim of the research was to describe the polymorphisms of the MTNR1A gene in three
Slovenian sheep breeds, and determine whether these polymorphisms affect reproductive …
