Sex determination in pigs

However, while sexed spermatozoa are commercially available for bovine, in other domestic species including the pig the technique is still at experimental level. The main objective of this thesis was to develop a protocol to efficiently apply flow cytometric sex-sorting procedure on boar spermatozoa. There is an individual variability among boars to withstand the sorting procedure by flow cytometry.

We have generated an improved assembly and gene annotation of the pig X Chromosome, and a first draft assembly of the pig Y Chromosome, by sequencing BAC and fosmid clones from Duroc animals and incorporating information from optical mapping and fiber-FISH. The X Chromosome carries annotated genes, of which are protein coding. Gene order closely matches that found in primates including humans and carnivores including cats and dogswhich is inferred to be ancestral.

This study describes the carcass and meat characteristics of native, Thai Kadon pigs. Female and male Kadon pigs were either housed individually or in groups and growth performance was measured. At the end of the feeding period, the pigs were killed and organ weights were determined.

Sex chromosomes are subject to evolutionary pressures distinct from the remainder of the genome, shaping their structure and sequence content. We are interested in the sex chromosomes of domestic pigs Sus scrofahow their structure and gene content compares and contrasts with other mammalian species, and the role of sex-linked genes in fertility. This requires an understanding of the XY-homologous sequence on these chromosomes.

Background Apr 14, 6 comments. When high-accuracy sex-sorted sperm becomes available to the global pig industry, the benefits realised by both commercial swine producers and genetics companies will be substantial. This is the view of Dr Jon Meadus, among many others.

Journal of Animal Science and Biotechnology. DecemberCite as. The aim of this study was to determine how maternal undernutrition during pregnancy and offspring birth-weight can affect the postnatal development of offspring under farm conditions, which may lead to consequences in its meat and carcass quality.

Multiplex polymerase chain reaction PCR assays were designed that incorporated primer pairs for the sex determining region on the Y chromosome, Sry, and one or two control sequences. A triplex and a duplex assay were created involving Sry and Dax, a single copy X chromosome gene which is involved in the female sex determination pathway. The third sequence in the triplex assay was a repetitive Y chromosome sequence, YR.

Among farm animals, pigs are known to show XX sex-reversal. In such cases the individuals are genetically female but exhibit a hermaphroditism, or a male phenotype. These losses result from sterility, urogenital infections and the carcasses being downgraded because of the risk of boar taint. It has been clearly demonstrated that the SRY gene is not involved in most cases of sex-reversal in pigs, and that autosomal recessive mutations remain to be discovered.
