A survey of relationships among rare breeds of swine
(University of Missouri--Columbia, 2014)

Rotational crossbreeding systems for pork producers (1993)
(University of Missouri--Columbia. Extension Division, 1993)
More than 90 percent of hogs marketed are of mixed breeding, an indication that crossbreeding is a well accepted management program. Yet crossbreeding alone does not guarantee efficient, profitable production. Choosing the system and breeds that fit...
Vitamin E and selenium in swine rations (1993)
(University of Missouri--Columbia. Extension Division, 1993)

Management and care of the herd boar (1995)

Purchasing a herd boar for commercial swine production (1995)
(University of Missouri--Columbia. Extension Division, 1995)

Vitamin requirements of swine (1990)
(University of Missouri--Columbia. Extension Division, 1990)
Vitamins are essential nutrients for swine. The trend toward complete confinement swine production, however, has focused more attention on the need to supplement practical rations with adequate dietary sources of vitamins. This Guide will help swine...
Forages for swine (1993)
(University of Missouri--Columbia. Extension Division, 1993)
Use of good pasture containing alfalfa, ladino clover, and grass can lower sow feed costs, help maintain high level reproductive capacity of boars, and in many cases increase litter size as compared to confinement raising of hogs.
Artificial insemination in swine : breeding the female (1997)
(University of Missouri--Columbia. Extension Division, 1997)

Infectious causes of infertility in sows (1993)
(University of Missouri--Columbia. Extension Division, 1993)
Any time a sow farrows prematurely, there is the fear that additional litters will be lost. An abortion rate of less than 2 percent is considered an acceptable level in most herds. Premature farrowing usually results from ...

Herd health programs for swine seedstock production (1993)
(University of Missouri--Columbia. Extension Division, 1993)
This guide outlines good health practices for a seedstock swine herd. Preventive practices are emphasized. Specifics vary from herd to herd and are too individualized to address in this guide. Specifics should be worked out with the herd...
Biosecurity for today's swine operation (2001)
(University of Missouri--Columbia. Extension Division, 2001)
Disease control is one of the most challenging areas for producers and veterinarians in swine production. Biosecurity is often perceived as keeping diseases out of a swine herd. However, excluding disease from a herd is nearly impossible because...
