Book excerpt: Excerpt from Swine Breeding Research at the Regional Swine Breeding Laboratory For the purpose of discovering, developing, and testing procedures of breeding that will result in improvement of swine, the Regional Swine Breeding Laboratory was established in 1937 with headquarters at Ames, Iowa. Investigations are coordinated and carried on co operatively between the United States Department of Agriculture and the agricultural experiment stations of Illinois, Indiana, Iowa, Kan sas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio. Oklahoma, South Dakota, and Wisconsin. The experiments initiated relate mainly to systems of breeding. Inbred lines are being formed within pure breeds and from cross bred foundations. The 40 lines already formed range from about 10 to 70 percent in inbreeding. In general there has been a slight decrease in fertility, vitality, and rate of growth as inbreeding has advanced. In the better lines, how ever, the decline noted has not been enough to be serious. In some lines these traits have remained at the level shown by the foundation stock, and other traits - economy of gain, for example - have im proved. In genetically good stock the rate of inbreeding can be increased at least 5 to 10 times as fast as that being practiced by breeders of the pure breeds without serious loss of individual merit.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Results of Swine Breeding Research: At the Regional Swine Breeding Research Laboratory and the Cooperating State Experiment Stations of Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, Oklahoma, South Dakota, and Wisconsin Structural and physiologic abnormalities in the reproductive tract were found to be responsible for some of the irregular breeding, low fertility, or complete sterility which occurs in both inbred and non inbred sows. Age of gilts at time of breeding showed important effects on the number of eggs shed and the number of pigs farrowed per litter. Records on carcasses of the various inbred lines and line crosses have shown definite differences between lines in carcass characteristics. Hogs of some of the inbred lines consistently yield excellent carcasses, while some lines yield excessively fat carcasses. Carcasses from line crosses out of lines which differed definitely in carcass characteristics generally were intermediate between the parent lines with regard to individual items. Usually the combination of characters expressed in crosses produced carcasses which were superior in desirability to either of the parent lines. Yield of the five primal cuts appears to be the most satisfactory single measure of carcass desirability which has been used but it does not evaluate quality of cuts. Composition of carcasses was altered by subjecting hogs of similar breeding to dif ferent levels of feeding.
