ANS 151 - Introduction to Animal Science Laboratory Swine Management In this laboratory, you will be exposed to several of the things that normally take place on a swine operation. These include: a) observing and assisting sows with farrowing (if any are farrowing); b) weighing baby piglets and collecting information on sows; and c) learning to identify common equipment and their uses. In addition, there is some supplemental information included as part of this laboratory handout that discusses various aspects of swine management. Based on this information you should: d) be able to identify the major anatomical parts of a pig; and f) be able to identify the following breeds of swine – Duroc, Hampshire, American Landrace, American Yorkshire, Meishan, Berkshire, Spot and Pietran (www.ansi.okstate.edu/breeds/). Overview of Daily Activities on Swine Operations Most swine operations operate on a weekly production system. This weans that all the major components of the production cycle – breeding, farrowing, weaning, movement from the nursery to finishing and marketing of finishing animals occur every week. Consequently, in addition to the daily responsibilities of feeding and observing animals, additional activities associated with breeding, farrowing, weaning, etc. must be performed on a daily or weekly basis. As a result, compared to the other animal units, there are usually more opportunities for students to observe and gain “hands-on” experience at the swine educational unit. Laboratory Exercises – Farrowing Management Prior to entry into the farrowing barn or rooms, sows are usually washed with a mild soap. This is an excellent way to reduce any possible disease transmission to the neonatal pigs. The farrowing house is the maternity ward of the swine operation. Consequently, strict hygiene, sanitation and cleanliness are maintained. In addition sows in most operations usually have to be moved from a gestation barn into a farrowing crate. When doing this it is important to handle the sow gently and let her move at her own pace. Undue stress late in pregnancy can stimulate the endocrine cascade that results in farrowing (parturition). You will have the opportunity to assist with moving sows from gestation to farrowing including washing them prior to their entry. Once a sow is in the farrowing barn, she will usually exhibit a fairly repeatable sequence
