This study aimed to evaluate the development of suckling piglets using morphometric parameters. Different models were created to predict the probability to occur any of the three weight classes (light, medium, and heavy) based on the piglets weaning weight. The variables in this research were birth weight (PWB), lactation length (Lac), and morphometric parameters, body length (BL), heart girth (HG), body mass index (BMI), ponderal index (PI), surface-mass ratio (SM), and birth order (BO). An adjustment of the ordinal regression was proposed to predict the weight classifications. The model with a significant effect of the Lac variables was selected. The light and heavy piglets, regardless of their morphometry, have a high chance of staying in the same weight class at weaning. However, this does not occur in medium piglets with diverse morphometry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
