Abstract:
... The number of teats is a morphological trait of high economic relevance for the pig industry. Here, to dissect the genomic architecture of this trait in the Italian Duroc pig population, we present the results of genome-wide association studies in this Italian heavy pig breed. A total of 1,162 pigs, for which the number of teats was recorded, was genotyped with two high-throughput single nucleotid ...

Abstract:
... The agouti signaling protein (ASIP) gene has a crucial role in pigmentation by encoding a protein that binds the melanocortin 1 receptor and stimulates the synthesis of pheomelanin rather than eumelanin. Several studies have suggested that an increased copy number of the ASIP gene might explain the white pigmentation of certain goat breeds, as previously demonstrated in sheep. In the current work, ...

Abstract:
... Hernia is a condition in which internal organs, most commonly the intestines, protrude through an opening in the layers of muscle and connective tissue. There are two major types of hernia—umbilical and inguinal. This pathology is a serious problem in pig production, leading to economic loss through the cost of surgical intervention, increased mortality rate, and reduced carcass value. The frequen ...

It leads to development of an abnormal reproductive tract in the female fetus, including the presence of testes or ovotestes. In pig production, such conditions can affect both reproductive performance and meat quality, through undesired boar taint. A common appro ...
