Freezing of boar spermatozoa: fertilizing capacity with concentrated semen and a new thawing procedure.
Production of transgenic rabbits, sheep and pigs by microinjection
Direct microinjection has been used to introduce foreign DNA into a number of terminally differentiated cell types as well as embryos of several species including sea urchin1, Candida elegans2,… Expand
Effects of stem cell factor and granulocyte macrophage-colony stimulating factor on survival of porcine type A spermatogonia cultured in KSOM.
Spermatogenesis is initiated with the divisions of the type A spermatogonial stem cells; however, the regulation of this stem cell population remains unknown. In order to obtain a better… Expand

Genetically enhanced cows resist intramammary Staphylococcus aureus infection
Mastitis, the most consequential disease in dairy cattle, costs the US dairy industry billions of dollars annually. To test the feasibility of protecting animals through genetic engineering,… Expand
Perspectives for artificial insemination and genomics to improve global swine populations.
Civilizations throughout the world continue to depend on pig meat as an important food source. Approximately 40% of the red meat consumed annually worldwide (94 million metric tons) is pig meat. Pig… Expand

Dual-energy x-ray absorptiometry (DXA) was used as a noninvasive method to measure the composition of pig carcasses. A total of 181 half-carcasses (10 to 51 kg, from pigs slaughtered at approximately… Expand
Genetic engineering of livestock.
Genetic engineering of livestock is expected to have a major effect on the agricultural industry. However, accurate assessment of the consequences of transgene expression is impossible without… Expand
