Constructing a simulated udder for neonatal piglets as an alternative to nurse sows

ABSTRACT An incubator with a simulated udder was constructed using information on piglet-sensory stimuli preferences. Neonatal piglets were randomly assigned to water in troughs (n = 38), milk-replacer (n = 36) or bovine-colostrum in simulated udder (n = 39). Weight was measured at 0, 0.5, 1, 2, 4, 6 and 8 hours, and rectal temperature at 0, 0.5, 1, 2 and 8 hours. An interaction between time and treatment affected weight change (P < 0.001), where all piglets lost weight during the first hour., Piglets with access to water continued loosing weight (82.1 ± 32.8 g over 8 h), milk-replacer-piglets gained 88.6 ± 53.2 g and bovine-colostrum-piglets gained 55.7 ± 66.5 g over 8 h. Overall, piglets with access to the simulated udder gained weight during their first eight hours postpartum. An interaction between temperature at first handling and time (P < 0.001) as well as an interaction between time and treatment (P < 0.001) affected temperature. Further development of the method could reduce the need for nurse sows.

期刊介绍： Acta Agriculturæ Scandinavica, Section A – Animal Science publishes results of original research in animal science and their applications related to the following topics: -Animal breeding and genetics -Molecular genetics -Animal physiology and reproduction -Nutrition and feeding -Animal behaviour and welfare -General animal husbandry and systems of production, including economic and technical aspects -Hygiene and quality of animal products In addition to original articles, covering basic as well as applied subjects, the journal features review articles and short communications. Acta Agriculturæ Scandinavica, Section A – Animal Science forms part of a trilogy of titles published on behalf of the Nordic Association of Agricultural Scientists (NJF). The series also includes Section B - Soil & Plant Science and the recently launched Section C - Food Economics . Acta Agriculturae Scandinavica A, B and C are available to purchase as a combined subscription. This provides access to all three journals in the series, and is available to institutional subscribers only. For full pricing information, please view the Taylor & Francis Journals Price List here.
