, which are noted for their ability to farrow and raise large litters, are the fifth most recorded breed of swine in the United States. The American descended from the Danish that originated in 1895. At that time the large white was brought from England and crossed with the native swine.

In , maternal heritabilities were estimated to be 0·11 for total number born , 0·06 for proportion alive at birth, and 0·08 for proportion survived from birth until 3 weeks.

The Danish are bred for pork production. Production and quality testing have become a regular part of the Danish swine improvement program. Primarily because of this breed, Denmark became the worlds chief bacon-exporting country and for many years refused to export purebred breeding stock to protect this position.

RSA to assess the status of and contribution of to the livelihood and fighting poverty in uThukela District. The study was motivated by the fact that no studies have been done to date to try and understand production in rural uThukela District. Furthermore, farmers were constantly raising concerns about issues such as

Background Understanding the genetic mechanisms that underlie meat quality traits is essential to improve pork quality. To date, most quantitative trait loci (QTL) analyses have been performed on F2 crosses between outbred strains and have led to the identification of numerous QTL. However, because linkage disequilibrium is high in such crosses, QTL mapping precision is unsatisfactory and …

An on- study was undertaken, firstly, to compare the Duroc and Hampshire as terminal sires in a three-way cross including the and Large White breeds and, secondly, to evaluate the latter cross against a two-way backcross involving the White breeds.
