Abstract

"The ovine POU1F1 gene is localized on chromosome 1 and it contains five introns and six exons. In different mammalian species some mutations in different exons are associated with different production traits. The aim of our research was to study the POU1F1 gene nucleotide sequence to detect possible polymorphisms and their relationships with milk productive traits in Sarda breed sheep. The study had been conducted on 140 ewes, 4 or 5 years old coming from a farm located in Sardinia. All the animals were multiparous, lactating and in their third to fifth lactation. Individual milk yield had been recorded monthly and for each sample fat, protein, casein, lactose, and somatic cell count values were analysed. A jugular blood sample was collected from each ewe to perform genomic DNA extraction. PCR, SSCP and sequencing analysis were carried out to examine the six exons to highlight possible SNPs.
